T1  - Sobre los orígenes y la evaluación de los Germanos en la literatura alemana de los siglos XVI
JF  - Revista de historiografía : rivista semestral
N2  - Los conceptos que tenían los habitantes del Sacro Imperio Romano sobre la nación germana respecto a su filiación étnica y sus orígenes cambian a partir del inicio de la historia moderna. A través del análisis de los ejemplos más relevantes el presente estudio traza las líneas maestras de este proceso de apropiación e interpretción del pasado que empieza con la recepción de la Germania de Tácito por los escritores humanistas y se prolonga a lo largo de los siglos XVII, XVIII y XIX.
N2  - The concepts which inhabitants of the Holy Roman Empire had of the German Nation regarding their ethnic affiliation and origins changed at the beginning of the Modern Age. Through the analysis of the most significant examples, this paper provides an outline of the development of the appropriation process and interpretation of the past that begins with the humanist writers’ reactions to the discovery of Tacitus’ work, Germania, and continues over the course the eighteenth and nineteenth centuries and the widespread belief that contemporary Germans and the Germani of classical authors are essentially identical.

T1  - In vitro degradation of wheat gluten fractions by Fusarium graminearum proteases
T2  - Postprints der Universität Potsdam : Mathematisch Naturwissenschaftliche Reihe
N2  - Fusarium spp. infection of cereal grain is a common problem, which leads to a dramatic loss of grain quality. The aim of the present study was to investigate the effect of Fusarium infection on the wheat storage protein gluten and its fractions, the gliadins and glutenins, in an in vitro model system. Gluten proteins were digested by F. graminearum proteases for 2, 4, 8 and 24 h, separated by Osborne fractionation and characterised by chromatographic (RP-HPLC) and electrophoretic analysis (SDS-Page). Gluten digestion by F. graminearum proteases showed in comparison with gliadins a preference for the glutenins whereas the HMW subfraction was at most affected. In comparison with a untreated control, the HMW subfraction was degraded of about 97% after 4 h incubation with Fusarium proteases. Separate digestion of gliadin and glutenin underlined the preference for HMW-GS. Analogue to the observed change in the gluten composition, the yield of the proteins extracted changed. A higher amount of glutenin fragments was found in the gliadin extraction solution after digestion and could mask a gliadin destruction at the same time. This observation can contribute to explain the frequently reported reduced glutenin amount parallel to an increase in gliadin quantity after Fusarium infection in grains.

T1  - Predator-induced changes of female mating preferences
BT  - innate and experiential effects
T2  - Postprints der Universität Potsdam : Mathematisch-Naturwissenschaftliche Reihe
N2  - Background

In many species males face a higher predation risk than females because males display elaborate traits that evolved under sexual selection, which may attract not only females but also predators. Females are, therefore, predicted to avoid such conspicuous males under predation risk. The present study was designed to investigate predator-induced changes of female mating preferences in Atlantic mollies (Poecilia mexicana). Males of this species show a pronounced polymorphism in body size and coloration, and females prefer large, colorful males in the absence of predators.
Results

In dichotomous choice tests predator-naïve (lab-reared) females altered their initial preference for larger males in the presence of the cichlid Cichlasoma salvini, a natural predator of P. mexicana, and preferred small males instead. This effect was considerably weaker when females were confronted visually with the non-piscivorous cichlid Vieja bifasciata or the introduced non-piscivorous Nile tilapia (Oreochromis niloticus). In contrast, predator experienced (wild-caught) females did not respond to the same extent to the presence of a predator, most likely due to a learned ability to evaluate their predators' motivation to prey.
Conclusions

Our study highlights that (a) predatory fish can have a profound influence on the expression of mating preferences of their prey (thus potentially affecting the strength of sexual selection), and females may alter their mate choice behavior strategically to reduce their own exposure to predators. (b) Prey species can evolve visual predator recognition mechanisms and alter their mate choice only when a natural predator is present. (c) Finally, experiential effects can play an important role, and prey species may learn to evaluate the motivational state of their predators.

T1  - Induced defences in marine and freshwater phytoplankton
BT  - a review
T2  - Postprints der Universität Potsdam : Mathematisch Naturwissenschaftliche Reihe
N2  - Many organisms have developed defences to avoid predation by species at higher trophic levels. The capability of primary producers to defend themselves against herbivores affects their own survival, can modulate the strength of trophic cascades and changes rates of competitive exclusion in aquatic communities. Algal species are highly flexible in their morphology, growth form, biochemical composition and production of toxic and deterrent compounds. Several of these variable traits in phytoplankton have been interpreted as defence mechanisms against grazing. Zooplankton feed with differing success on various phytoplankton species, depending primarily on size, shape, cell wall structure and the production of toxins and deterrents. Chemical cues associated with (i) mechanical damage, (ii) herbivore presence and (iii) grazing are the main factors triggering induced defences in both marine and freshwater phytoplankton, but most studies have failed to disentangle the exact mechanism(s) governing defence induction in any particular species. Induced defences in phytoplankton include changes in morphology (e.g. the formation of spines, colonies and thicker cell walls), biochemistry (such as production of toxins, repellents) and in life history characteristics (formation of cysts, reduced recruitment rate). Our categorization of inducible defences in terms of the responsible induction mechanism provides guidance for future work, as hardly any of the available studies on marine or freshwater plankton have performed all the treatments that are required to pinpoint the actual cue(s) for induction. We discuss the ecology of inducible defences in marine and freshwater phytoplankton with a special focus on the mechanisms of induction, the types of defences, their costs and benefits, and their consequences at the community level.

T1  - Insights into the high-energy gamma-Ray emission of markarian 501 fromextensive multifrequency observations in the fermi era
JF  - The astrophysical journal : an international review of spectroscopy and astronomical physics
N2  - We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average Large Area Telescope (LAT) gamma-ray spectrum of Mrk 501 can be well described by a single power-law function with a photon index of 1.78 +/- 0.03. While we observe relatively mild flux variations with the Fermi-LAT (within less than a factor of two), we detect remarkable spectral variability where the hardest observed spectral index within the LAT energy range is 1.52 +/- 0.14, and the softest one is 2.51 +/- 0.20. These unexpected spectral changes do not correlate with the measured flux variations above 0.3 GeV. In this paper, we also present the first results from the 4.5 month long multifrequency campaign (2009 March 15-August 1) on Mrk 501, which included the Very Long Baseline Array (VLBA), Swift, RXTE, MAGIC, and VERITAS, the F-GAMMA, GASP-WEBT, and other collaborations and instruments which provided excellent temporal and energy coverage of the source throughout the entire campaign. The extensive radio to TeV data set from this campaign provides us with the most detailed spectral energy distribution yet collected for this source during its relatively low activity. The average spectral energy distribution of Mrk 501 is well described by the standard one-zone synchrotron self-Compton (SSC) model. In the framework of this model, we find that the dominant emission region is characterized by a size less than or similar to 0.1 pc (comparable within a factor of few to the size of the partially resolved VLBA core at 15-43 GHz), and that the total jet power (similar or equal to 10(44) erg s(-1)) constitutes only a small fraction (similar to 10(-3)) of the Eddington luminosity. The energy distribution of the freshly accelerated radiating electrons required to fit the time-averaged data has a broken power-law form in the energy range 0.3 GeV-10 TeV, with spectral indices 2.2 and 2.7 below and above the break energy of 20 GeV. We argue that such a form is consistent with a scenario in which the bulk of the energy dissipation within the dominant emission zone of Mrk 501 is due to relativistic, proton-mediated shocks. We find that the ultrarelativistic electrons and mildly relativistic protons within the blazar zone, if comparable in number, are in approximate energy equipartition, with their energy dominating the jet magnetic field energy by about two orders of magnitude.

T1  - Properties of soils from the Swedish long-term fertility experiments  VI. Mapping soil electrical conductivity with different geophysical methods
JF  - Acta agriculturae Scandinavica : Section B, Soil and plant science
N2  - Swedish long-term soil fertility experiments were used to investigate the effect of texture and fertilization regime on soil electrical conductivity. In one geophysical approach, fields were mapped to characterize the horizontal variability in apparent electrical conductivity down to 1.5 m soil depth using an electromagnetic induction meter (EM38 device). The data obtained were geo-referenced by dGPS. The other approach consisted of measuring the vertical variability in electrical conductivity along transects using a multi-electrode apparatus for electrical resistivity tomography (GeoTom RES/IP device) down to 2 m depth. Geophysical field work was complemented by soil analyses. The results showed that despite 40 years of different fertilization regimes, treatments had no significant effects on the apparent electrical conductivity. Instead, the comparison of sites revealed high and low conductivity soils, with gradual differences explained by soil texture. A significant, linear relationship found between apparent electrical conductivity and soil clay content explained 80% of the variability measured. In terms of soil depth, both low and high electrical conductivity values were measured. Abrupt changes in electrical conductivity within a field revealed the presence of 'deviating areas'. Higher values corresponded well with layers with a high clay content, while local inclusions of coarse-textured materials caused a high variability in conductivity in some fields. The geophysical methods tested provided useful information on the variability in soil texture at the experimental sites. The use of spatial EC variability as a co-variable in statistical analysis could be a complementary tool in the evaluation of experimental results.

T1  - Die Grenzen der Toleranz : rechtsextremes Milieu und demokratische Gesellschaft in Brandenburg ; Bilanz und Perspektiven
N2  - Die Beiträge des vorliegenden Sammelbandes gehen auf die wissenschaftliche Fachtagung „Grenzen der Toleranz. Rechtsextremes Milieu und demokratische Gesellschaft in Brandenburg - Bilanz und Perspektiven" zurück, die im Mai 2009 in Potsdam stattfand. Auf der Tagung hielten verschiedene Wissenschaftler Vorträge, die ihrerseits durch Praktiker/innen mittels „Kommentaren aus der Praxis“ gespiegelt wurden. Die meisten Vorträge der Tagung finden sich in diesem Band nun in überarbeiteter, in der Regel erweiterter und aktualisierter Form wieder. In einem Fall wurde ein Text aufgenommen, der aus einem längeren „Kommentar aus der Praxis“ entstanden ist. Die Beiträge kreisen um das Problem des Rechtsextremismus, seinen Erscheinungsformen und Praktiken in Brandenburg und darüber hinaus, und beleuchten die staatlichen und zivilgesellschaftlichen Gegenmaßnahmen und –strategien. Dabei wird deutlich: Brandenburg hat zwar noch ein Rechtsextremismusproblem - aber auch vielfältige Strategien und Erfahrungen in der erfolgreichen Auseinandersetzung mit diesem Phänomen.
N2  - This volume combines contributions to a conference Grenzen der Toleranz. Rechtsextremes Milieu und demokratische Gesellschaft in Brandenburg – Bilanz und Perspektiven („The Limits of Tolerance. Far Right Milieus and Democratic Society in Brandenburg – Results and Perspectives“) held in Potsdam in May 2009. At this conference, several scholars held lectures and were commented by practitioners. The contributions to the book discuss different aspects of the far right movements and its praxis in Brandenburg and beyond, and they introduce and analyze the reactions and counter-activities of the state as well as the civil society. Thus, it becomes obvious: Right wing extremism is still a challenge for democratic society in Brandenburg, but this society has also developed multiple and effective strategies to react.

T1  - Fluid Migration above a Subducted Slab-Constraints on Amount, Pathways and Major Element Mobility from Partially Overprinted Eclogite-facies Rocks (Sesia Zone, Western Alps)
JF  - Journal of petrology
N2  - The Western Alpine Sesia-Lanzo Zone (SLZ) is a sliver of eclogite-facies continental crust exhumed from mantle depths in the hanging wall of a subducted oceanic slab. Eclogite-facies felsic and basic rocks sampled across the internal SLZ show different degrees of retrograde metamorphic overprint associated with fluid influx. The weakly deformed samples preserve relict eclogite-facies mineral assemblages that show partial fluid-induced compositional re-equilibration along grain boundaries, brittle fractures and other fluid pathways. Multiple fluid influx stages are indicated by replacement of primary omphacite by phengite, albitic plagioclase and epidote as well as partial re-equilibration and/or overgrowths in phengite and sodic amphibole, producing characteristic step-like compositional zoning patterns. The observed textures, together with the map-scale distribution of the samples, suggest open-system, pervasive and reactive fluid flux across large rock volumes above the subducted slab. Thermodynamic modelling indicates a minimum amount of fluid of 0 center dot 1-0 center dot 5 wt % interacting with the wall-rocks. Phase relations and reaction textures indicate mobility of K, Ca, Fe and Mg, whereas Al is relatively immobile in these medium-temperature-high-pressure fluids. Furthermore, the thermodynamic models show that recycling of previously fractionated material, such as in the cores of garnet porphyroblasts, largely controls the compositional re-equilibration of the exhumed rock body.

T1  - Fluid migration above a subducted slab - Thermodynamic and trace element modelling of fluid-rock interaction in partially overprinted eclogite-facies rocks (Sesia Zone, Western Alps)
JF  - Earth & planetary science letters
N2  - The amount and composition of subduction zone fluids and the effect of fluid-rock interaction at a slab-mantle interface have been constrained by thermodynamic and trace element modelling of partially overprinted blueschist-facies rocks from the Sesia Zone (Western Alps). Deformation-induced differences in fluid flux led to a partial preservation of pristine mineral cores in weakly deformed samples that were used to quantify Li, B, Stand Pb distribution during mineral growth, -breakdown and modification induced by fluid-rock interaction. Our results show that Li and 13 budgets are fluid-controlled, thus acting as tracers for fluid-rock interaction processes, whereas Stand Pb budgets are mainly controlled by the fluid-induced formation of epidote. Our calculations show that fluid-rock interaction caused significant Li and B depletion in the affected rocks due to leaching effects, which in turn can lead to a drastic enrichment of these elements in the percolating fluid. Depending on available fluid-mineral trace element distribution coefficients modelled fluid rock ratios were up to 0.06 in weakly deformed samples and at least 0.5 to 4 in shear zone mylonites. These amounts lead to time integrated fluid fluxes of up to 1.4-10(2) m(3) m(-2) in the weakly deformed rocks and 1-8-10(3) m(3) m(-2) in the mylonites. Combined thermodynamic and trace element models can be used to quantify metamorphic fluid fluxes and the associated element transfer in complex, reacting rock systems and help to better understand commonly observed fluid-induced trace element trends in rocks and minerals from different geodynamic environments.

T1  - The time of eclogite formation in the ultrahigh pressure rocks of the Sulu terrane Constraints from Lu-Hf garnet geochronology
JF  - Lithos : an international journal of mineralogy, petrology, and geochemistry
N2  - Eclogites from the main borehole of the Chinese Continental Scientific Drilling project yield highly precise Lu-Hf garnet-clinopyroxene ages of 216.9 +/- 1.2 Ma (four samples) and 220.5 +/- 2.7 Ma (one sample). The spatial distribution of the rare earth elements in garnet is consistent with the preservation of primary growth zoning, unmodified by diffusion, which supports the interpretation that the Lu-Hf ages date the time of formation of garnet, the major rock forming mineral in the eclogites. The preservation of primary REE-zoning, despite peak metamorphic temperatures around 800-850 degrees C. indicates that the Lu-Hf chronometer is perfectly suitable to date garnet-forming reactions in high grade rocks. The range of Lu-Hf ages for eclogites in the Dabie-Sulu UHP terrane point to episodic rather than continuous growth of garnets and thus punctuated metamorphism during the collision of the North China Block and the Yangtze Block. The U-Pb ages and Hf-isotope systematics of zircon grains from one eclogite sample imply a protracted geologic history of the eclogite precursors that started around 2 Ga and culminated in the UHP metamorphism around 220 Ma.

T1  - Diamond and coesite discovered in Saxony-type granulite solution to the Variscan garnet peridotite enigma
JF  - Geology
N2  - The pressures required for diamond and coesite formation far exceed conditions reached by even the deepest present-day orogenic crustal roots. Therefore the occurrence of metamorphosed continental crust containing these minerals requires processes other than crustal thickening to have operated in the past. Here we report the first in situ finding of diamond and coesite, characterized by micro-Raman spectroscopy, in high-pressure granulites otherwise indistinguishable from granulites found associated with garnet peridotite throughout the European Variscides. Our discovery confirms the provenance of Europe's first reliable diamond, the "Bohemian diamond," found in A.D. 1870, and also represents the first robust evidence for ultrahigh-pressure conditions in a major Variscan crustal rock type. A process of deep continental subduction is required to explain the metamorphic pressures and the granulite-garnet peridotite association, and thus tectonometamorphic models for these rocks involving a deep orogenic crustal root need to be significantly modified.

T1  - Full mitochondrial genome sequences of two endemic Philippine hornbill species (Aves: Bucerotidae) provide evidence for pervasive mitochondrial DNA recombination
JF  - BMC genomics
N2  - Background: Although nowaday it is broadly accepted that mitochondrial DNA (mtDNA) may undergo recombination, the frequency of such recombination remains controversial. Its estimation is not straightforward, as recombination under homoplasmy (i.e., among identical mt genomes) is likely to be overlooked. In species with tandem duplications of large mtDNA fragments the detection of recombination can be facilitated, as it can lead to gene conversion among duplicates. Although the mechanisms for concerted evolution in mtDNA are not fully understood yet, recombination rates have been estimated from "one per speciation event" down to 850 years or even "during every replication cycle".
 Results: Here we present the first complete mt genome of the avian family Bucerotidae, i.e., that of two Philippine hornbills, Aceros waldeni and Penelopides panini. The mt genomes are characterized by a tandemly duplicated region encompassing part of cytochrome b, 3 tRNAs, NADH6, and the control region. The duplicated fragments are identical to each other except for a short section in domain I and for the length of repeat motifs in domain III of the control region. Due to the heteroplasmy with regard to the number of these repeat motifs, there is some size variation in both genomes; with around 21,657 bp (A. waldeni) and 22,737 bp (P. panini), they significantly exceed the hitherto longest known avian mt genomes, that of the albatrosses. We discovered concerted evolution between the duplicated fragments within individuals. The existence of differences between individuals in coding genes as well as in the control region, which are maintained between duplicates, indicates that recombination apparently occurs frequently, i. e., in every generation.
 Conclusions: The homogenised duplicates are interspersed by a short fragment which shows no sign of recombination. We hypothesize that this region corresponds to the so-called Replication Fork Barrier (RFB), which has been described from the chicken mitochondrial genome. As this RFB is supposed to halt replication, it offers a potential mechanistic explanation for frequent recombination in mitochondrial genomes.

T1  - Patterns of local and regional genetic structuring in the meadow grasshopper, Chorthippus parallelus (Orthoptera: Acrididae), in Central Germany revealed using microsatellite markers
JF  - Biological journal of the Linnean Society : a journal of evolution
N2  - The meadow grasshopper, Chorthippus parallelus (Zetterstedt), is common and widespread in Central Europe, with a low dispersal range per generation. A population study in Central Germany (Frankenwald and Thuringer Schiefergebirge) showed strong interpopulation differences in abundance and individual fitness. We examined genetic variability using microsatellite markers within and between 22 populations in a short-to long-distance sampling (19 populations, Frankenwald, Schiefergebirge, as well as a southern transect), and in the Erzgebirge region (three populations), with the latter aiming to check for effects as a result of historical forest cover. Of the 671 C. parallelus captured, none was macropterous (functionally winged). All populations showed a high level of expected and observed heterozygosity (mean 0.80-0.90 and 0.60-0.75, respectively), whereas there was evidence of inbreeding (F(IS) values all positive). Allelic richness for all locus-population combinations was high (mean 9.3-11.2), whereas alleles per locus ranged from 15-62. At a local level, genic and genotypic differences were significant. Pairwise F(ST) values were in the range 0.00-0.04, indicating little interpopulation genetic differentiation. Similarly, the calculated gene flow was very high, based on the respective F(ST) (19.5) and using private alleles (7.7). A Neighbour-joining tree using Nei's D(A) and principal coordinate analysis separated two populations that were collected in the Erzgebirge region. Populations from this region may have escaped the effects of the historical forest cover. The visualization of the spatial arrangement of genotypes revealed one geographical barrier to gene flow in the short-distance sampling.

T1  - Environmental variability in Lake Naivasha, Kenya, over the last two centuries
JF  - Journal of paleolimnolog
N2  - Lake Naivasha, Kenya, is one of a number of freshwater lakes in the East African Rift System. Since the beginning of the twentieth century, it has experienced greater anthropogenic influence as a result of increasingly intensive farming of coffee, tea, flowers, and other horticultural crops within its catchment. The water-level history of Lake Naivasha over the past 200 years was derived from a combination of instrumental records and sediment data. In this study, we analysed diatoms in a lake sediment core to infer past lacustrine conductivity and total phosphorus concentrations. We also measured total nitrogen and carbon concentrations in the sediments. Core chronology was established by (210)Pb dating and covered a similar to 186-year history of natural (climatic) and human-induced environmental changes. Three stratigraphic zones in the core were identified using diatom assemblages. There was a change from littoral/epiphytic diatoms such as Gomphonema gracile and Cymbella muelleri, which occurred during a prolonged dry period from ca. 1820 to 1896 AD, through a transition period, to the present planktonic Aulacoseira sp. that favors nutrient-rich waters. This marked change in the diatom assemblage was caused by climate change, and later a strong anthropogenic overprint on the lake system. Increases in sediment accumulation rates since 1928, from 0.01 to 0.08 g cm(-2) year(-1) correlate with an increase in diatom-inferred total phosphorus concentrations since the beginning of the twentieth century. The increase in phosphorus accumulation suggests increasing eutrophication of freshwater Lake Naivasha. This study identified two major periods in the lake's history: (1) the period from 1820 to 1950 AD, during which the lake was affected mainly by natural climate variations, and (2) the period since 1950, during which the effects of anthropogenic activity overprinted those of natural climate variation.

T1  - A Gene Duplication/Loss Event in the Ribulose-1,5-Bisphosphate-Carboxylase/Oxygenase (Rubisco) Small Subunit Gene Family among Accessions of Arabidopsis thaliana
JF  - Molecular biology and evolution
N2  - Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase; EC 4.1.1.39), the most abundant protein in nature, catalyzes the assimilation of CO(2) (worldwide about 10(11) t each year) by carboxylation of ribulose-1,5-bisphosphate. It is a hexadecamer consisting of eight large and eight small subunits. Although the Rubisco large subunit (rbcL) is encoded by a single gene on the multicopy chloroplast genome, the Rubisco small subunits (rbcS) are encoded by a family of nuclear genes. In Arabidopsis thaliana, the rbcS gene family comprises four members, that is, rbcS-1a, rbcS-1b, rbcS-2b, and rbcS-3b. We sequenced all Rubisco genes in 26 worldwide distributed A. thaliana accessions. In three of these accessions, we detected a gene duplication/loss event, where rbcS-1b was lost and substituted by a duplicate of rbcS-2b (called rbcS-2b*). By screening 74 additional accessions using a specific polymerase chain reaction assay, we detected five additional accessions with this duplication/loss event. In summary, we found the gene duplication/loss in 8 of 100 A. thaliana accessions, namely, Bch, Bu, Bur, Cvi, Fei, Lm, Sha, and Sorbo. We sequenced an about 1-kb promoter region for all Rubisco genes as well. This analysis revealed that the gene duplication/loss event was associated with promoter alterations (two insertions of 450 and 850 bp, one deletion of 730 bp) in rbcS-2b and a promoter deletion (2.3 kb) in rbcS-2b* in all eight affected accessions. The substitution of rbcS-1b by a duplicate of rbcS-2b (i.e., rbcS-2b*) might be caused by gene conversion. All four Rubisco genes evolve under purifying selection, as expected for central genes of the highly conserved photosystem of green plants. We inferred a single positive selected site, a tyrosine to aspartic acid substitution at position 72 in rbcS-1b. Exactly the same substitution compromises carboxylase activity in the cyanobacterium Anacystis nidulans. In A. thaliana, this substitution is associated with an inferred recombination. Functional implications of the substitution remain to be evaluated.

T1  - Alien eggs in duck nests brood parasitism or a help from Grandma?
JF  - Molecular ecology
N2  - Intraspecific brood parasitism (IBP) is a remarkable phenomenon by which parasitic females can increase their reproductive output by laying eggs in conspecific females' nests in addition to incubating eggs in their own nest. Kin selection could explain the tolerance, or even the selective advantage, of IBP, but different models of IBP based on game theory yield contradicting predictions. Our analyses of seven polymorphic autosomal microsatellites in two eider duck colonies indicate that relatedness between host and parasitizing females is significantly higher than the background relatedness within the colony. This result is unlikely to be a by-product of relatives nesting in close vicinity, as nest distance and genetic identity are not correlated. For eider females that had been ring-marked during the decades prior to our study, our analyses indicate that (i) the average age of parasitized females is higher than the age of nonparasitized females, (ii) the percentage of nests with alien eggs increases with the age of nesting females, (iii) the level of IBP increases with the host females' age, and (iv) the number of own eggs in the nest of parasitized females significantly decreases with age. IBP may allow those older females unable to produce as many eggs as they can incubate to gain indirect fitness without impairing their direct fitness: genetically related females specialize in their energy allocation, with young females producing more eggs than they can incubate and entrusting these to their older relatives. Intraspecific brood parasitism in ducks may constitute cooperation among generations of closely related females.

T1  - Molecular profiling of diatom assemblages in tropical lake sediments using taxon-specific PCR and Denaturing High-Performance Liquid Chromatography (PCR-DHPLC)
JF  - Molecular ecology resources
N2  - Here we present a protocol to genetically detect diatoms in sediments of the Kenyan tropical Lake Naivasha, based on taxon-specific PCR amplification of short fragments (approximately 100 bp) of the small subunit ribosomal (SSU) gene and subsequent separation of species-specific PCR products by PCR-based denaturing high-performance liquid chromatography (DHPLC). An evaluation of amplicons differing in primer specificity to diatoms and length of the fragments amplified demonstrated that the number of different diatom sequence types detected after cloning of the PCR products critically depended on the specificity of the primers to diatoms and the length of the amplified fragments whereby shorter fragments yielded more species of diatoms. The DHPLC was able to discriminate between very short amplicons based on the sequence difference, even if the fragments were of identical length and if the amplicons differed only in a small number of nucleotides. Generally, the method identified the dominant sequence types from mixed amplifications. A comparison with microscopic analysis of the sediment samples revealed that the sequence types identified in the molecular assessment corresponded well with the most dominant species. In summary, the PCR-based DHPLC protocol offers a fast, reliable and cost-efficient possibility to study DNA from sediments and other environmental samples with unknown organismic content, even for very short DNA fragments.

Zoological Studies 50(2): 220-229. In this study we assessed levels of genetic divergence and variability in 208 individuals of the supralittoral sandhopper Macarorchestia remyi, a species strictly associated with rotted wood stranded on sand beaches, by analyzing sequence polymorphisms in a fragment of the mitochondrial DNA (mtDNA) gene coding cytochrome oxidase subunit I (COI). The geographical distribution and ecology of the species are poorly known. The study includes 1 Tyrrhenian and 2 Adriatic populations sampled along the Italian peninsula plus a single individual found on Corfu Is. (Greece). The Tyrrhenian population was sampled monthly for 1 yr. Genetic data revealed a deep phylogeographic break between the Tyrrhenian and Adriatic populations with no shared haplotypes. The single individual collected on Corfu Is. carried the most common haplotype found in the Tyrrhenian population. A mismatch analysis could not reject the hypothesis of a sudden demographic expansion in almost all but 2 monthly samples. When compared to previous genetic data centered on a variety of Mediterranean talitrids, our results place M. remyi among those species with profound intraspecific divergence (sandhoppers) and dissimilar from beachfleas, which generally display little population genetic structuring.

T1  - Genetically distinct population of Bengal tiger (Panthera tigris tigris) in Terai Arc Landscape (TAL) of India
JF  - Mammalian biology = Zeitschrift für Säugetierkunde
N2  - We analyzed mtDNA polymorphisms (a total of 741 bp from a part of conserved control region, ND5, ND2, Cyt b and 12S) in 91 scats and 12 tissue samples of Bengal tiger (Panthera tigris tigris) populations across Terai Arc Landscape (TAL) located at the foothills of Himalayas in North Western India, Buxa Tiger Reserve (BTR), and North East India. In TAL and BTR, we found a specific haplotype at high frequency, which was absent elsewhere, indicating a genetically distinct population in these regions. Within the TAL region, there is some evidence for genetic isolation of the tiger populations west of river Ganges, i.e., in the western part of Rajaji National Park (RNP). Although the river itself might not constitute a significant barrier for tigers, recent human-induced changes in habitat and degradation of the Motichur-Chilla Corridor connecting the two sides of the tiger habitat of RNP might effectively prevent genetic exchange. A cohesive population is observed for the rest of the TAL. Even the more eastern BTR belongs genetically to this unit, despite the present lack of a migration corridor between BTR and TAL. In spite of a close geographic proximity, Chitwan (Nepal) constitutes a tiger population genetically different from TAL. Moreover, it is observed that the North East India tiger populations are genetically different from TAL and BTR, as well as from the other Bengal tiger populations in India.

T1  - Sexual and natural selection on morphological traits in a marine amphipod, Pontogammarus maeoticus (Sowinsky, 1894)
JF  - Marine biology research
N2  - Sexual selection often leads to sexual dimorphism, where secondary sexual traits are more expressed in the male sex. This may be due, for example, to increased fighting or mate-guarding abilities of males expressing those traits. We investigated sexually dimorphic traits in four populations of a marine amphipod, Pontogammarus maeoticus (Gammaridea: Pontogammaridae), the most abundant amphipod species in the sublittoral zone along the southern shoreline of the Caspian Sea. Male amphipods are typically larger in body size than females, and have relatively larger posterior gnathopods and antennae. However, it remains to be studied for most other body appendages whether or not, and to what extent, they are sexually dimorphic. Using Analysis of Covariance (ANCOVA), we compared the relationships between body size and trait expression for 35 metric characters between males and females, and among the four populations examined by performing three different Discriminant Function Analyses (DFA). We detected several thus far undescribed sexual dimorphic traits such as the seventh peraeopods or the epimeral plates. We also found that the size of the propodus of the first and second gnathopods increases with increasing body size, and this allometric increase was stronger in males than in females. Finally, we found that the degree of sexual dimorphism in the expression of the width of the third epimeral plate varies across sites, suggesting that differences in ecology might affect the strength of sexual selection in different populations.

T1  - LNA-clamp-PCR zum sensitiven Nachweis von Punktmutationen im Rahmen der Entwicklung eines Darmkrebsfrüherkennungstests
T1  - LNA-clamp-PCR as a method for sensitive detection of point mutations as part of the development of an assay for the early diagnosis of colon cancer
N2  - Darmkrebs ist die zweithäufigste malignombedingte Todesursache in den westlichen Industrieländern. Durch eine frühzeitige Diagnose besteht jedoch eine hohe Chance auf Heilung. Der Goldstandard zur Darmkrebsfrüherkennung ist gegenwärtig die Koloskopie. Eine Darmspiegelung ist jedoch invasiv und mit Unannehmlichkeiten für den Patienten verbunden. Die Akzeptanz in der Bevölkerung ist daher gering. Ziel des BMBF- Projektes „Entwicklung eines nichtinvasiven Nachweissystems zur Früherkennung von humanem Darmkrebs“, in dessen Rahmen diese Arbeit entstand, ist die Bereitstellung eines nichtinvasiven Nachweisverfahrens zur Darmkrebsfrüherkennung. Der Nachweis soll über die Detektion von aus neoplastischen Zellen stammender DNA in Stuhl erfolgen. Die Entartung dieser Zellen beruht auf Veränderungen im Erbgut, welches unter anderem Mutationen sind. Im ersten Teil des BMBF-Projektes wurde ein Set von Mutationen zusammengestellt, welches eine hohe Sensitivität für Vorstufen von Darmkrebs aufweist. Ziel dieser Arbeit war es, eine Nachweismethode für die zuvor identifizierten Punktmutationen zu entwickeln. Das Nachweisverfahren musste dabei unempfindlich gegen einen hohen Hintergrund nichtmutierter DNA sein, da im Stuhl geringe Mengen DNA aus neoplastischen Zellen bei einem hohen Hintergrund von DNA aus gesunden Zellen vorliegen. Hierzu wurden Plasmidmodellsysteme für die aus dem Marker-Set stammenden Genfragmente BRAF und dessen Mutante V600E, CTNNB1 und T41I, T41A, S45P und K-ras G12C hergestellt. Mit Hilfe dieser Plasmidmodellsysteme wurde dann das Nachweissystem entwickelt. Der entscheidende Schritt für die Detektion von Punktmutationen bei hohem Wildtypüberschuss ist eine vorhergehende Anreicherung. In der vorliegenden Arbeit wurde dazu die Methode der LNA-clamp-PCR (locked nucleic acid) etabliert. Die Bewertung der erzielten Anreicherung erfolgte über das relative Detektionslimit. Zur Bestimmung des Detektionslimits wurde die Schmelzkurvenanalyse von Hybridisierungssonden eingesetzt; diese wurde im Rahmen dieser Arbeit für die drei oben genannten Genfragmente und ihre Mutanten entwickelt. Die LNA-clamp-PCR wird in Anwesenheit eines LNA-Blockers durchgeführt. Das Nukleotidanalogon LNA weist im Vergleich zu DNA eine erhöhte Affinität zu komplementären DNA-Strängen auf. Gleichzeitig kommt es bei Anwesenheit einer Basenfehlpaarung zu einer größeren Destabilisierung der Bindung. Als Blocker werden kurze LNA-DNA-Hybridoligonukleotide eingesetzt, die den mutierten Sequenzbereich überspannen und selbst der Wildtypsequenz entsprechen. Durch Bindung an die Wildtypsequenz wird deren Amplifikation während der PCR verhindert (clamp = arretieren, festklemmen). Der Blocker selbst wird dabei nicht verlängert. Der Blocker bindet unter optimalen Bedingungen jedoch nicht an die mutierte Sequenz. Die Mutante wird daher ungehindert amplifiziert und somit gegenüber dem Wildtyp-Fragment angereichert. Die Position des Blockers kann im Bindungsbereich eines der Primer sein und hier dessen Hybridisierung an dem Wildtyp-Fragment verhindern oder zwischen den beiden Primern liegen und so die Synthese durch die Polymerase inhibieren. Die Anwendbarkeit beider Systeme wurde in dieser Arbeit gezeigt. Die LNA-clamp-PCR mit Primerblocker wurde für BRAF etabliert. Es wurde ein Detektionslimit von mindestens 1:100 erzielt. Die LNA-clamp-PCR mit Amplifikationsblocker wurde erfolgreich für BRAF, K-ras und CTNNB1: T41I, T41A mit einem Detektionslimit von 1:1000 bis 1:10 000 entwickelt. In Stuhlproben liegt DNA aus neoplastischen Zellen nach Literaturangaben zu einem Anteil von 1% bis 0,1% vor. Die LNA-clamp-PCR weist also mit Amplifikationsblockern ein ausreichend hohes Detektionslimit für die Analyse von Stuhlproben auf. Durch die erfolgreiche Etablierung der Methode auf drei verschiedenen Genfragmenten und vier unterschiedlichen Punktmutationen konnte deren universelle Einsetzbarkeit gezeigt werden. Für die Ausweitung der LNA-clamp-PCR auf die übrigen Mutationen des Marker-Sets wurden Richtlinien ausgearbeitet und die Blockereffizienz als Kennzahl eingeführt. Die LNA-clamp-PCR ist ein schnelles, kostengünstiges Verfahren, welches einen geringen Arbeitsaufwand erfordert und wenig fehleranfällig ist. Sie ist somit ein geeignetes Anreicherungsverfahren für Punktmutationen in einem diagnostischen System zur Darmkrebsfrüherkennung. Darüber hinaus kann die LNA-clamp-PCR auch in anderen Bereichen, in denen die Detektion von Punktmutationen in einem hohen Wildtyphintergrund erforderlich ist, eingesetzt werden.
N2  - Colon cancer is the second leading cause of cancer related deaths in the western world. However if diagnosed early there is a great chance curing the disease. Coloscopy is the gold standard for early detection of colorectal cancer today. Its greatest disadvantage is the fact that it is an invasive technique and provides some discomfort for the patients. Therefore, the compliance to undergo such a procedure is extremely low. This work was generated in the context of the BMBF-project „Development of a non-invasive assay for the early detection of preneoplastic and neoplastic lesions in the human colon“. The aim of the work described here is the development of a non-invasive assay for the early detection of colon cancer. The assay should detect DNA from neoplastic cells in feces samples. The transformation of these cells is based on alterations in the genome predominantly mutations. In the first part of the BMBF-project a mutation panel with high sensitivity for preneoplastic lesions of colon cancer was determined. The aim of this work was to develop a detection method for the point mutations of the determined mutation panel. The rare mutant DNA needs to be detected in the presence of a great amount of wild-type DNA shed from healthy tissue. The assay system needs to be insensitive to this high background of healthy DNA. Therefore a model system of plasmid DNA containing gene fragments of BRAF and its mutation V600E, CTNNB1 and T41I, T41A, S45P and K-ras G12C obtained from the marker panel was established. Using these plasmid system the detection method was developed. The most critical parameter for the detection of rare point mutations is an enrichment of these rare DNA molecules. In this work LNA-clamp-PCR (locked nucleic acid) technology was used to enrich the mutant DNA.. For the estimation of the achieved enrichment the relative detection limit was used. The detection limit was determined by melting curve analysis of hybridization probes. These assays were established in the present work for the three above mentioned gene fragments. LNA-clamp-PCR is performed in the presence of an LNA blocker. LNA is a synthetic DNA analog. LNA nucleotide analog bind to complementary DNA strands with higher affinity. In addition a single mismatch in the LNA-DNA duplex causes a much greater destabilization compared to a DNA-DNA duplex. Short LNA-DNA-hybrids were used as clamp, which cover the mutated region and represent the wild-type sequence. Within an appropriate temperature range, LNA can specifically bind to wild type template and can inhibit its amplification. The clamp itself will not be elongated. Under optimal conditions the LNA clamp will not interfere with the amplification of the mismatched template. Therefore the mutated gene fragment will be enriched in comparison to the wild-type. The position of the LNA clamp can either be at the primer binding site inhibiting primer hybridization on the wild-type fragment or the LNA clamp is positioned between the two primer binding sites inhibiting chain elongation of the perfectly matched template. In the present work both systems were applied. For the gene fragment BRAF the LNA was used at the primer binding site. The achieved detection limit was at least 1:100. The LNA-clamp-PCR with LNA inhibiting the chain elongation were developed successfully for BRAF, K-ras and CTNNB1: T41I, T41A achieving a detection limit of 1:1000 to 1:10 000. According to the literature 1% to 0.1% of the DNA in feces derives from neoplastic cells. Therefore the detection limit achieved by LNA-clamp-PCR with LNA inhibiting chain elongation would be sufficient for analyzing feces samples. LNA-clamp-PCR protocols were established for three different gene fragments and four diverse point mutations indicating that the technology can generally be used for high sensitive detection of DNA mutations. For the development of LNA-clamp-PCR protocols for the other mutations of the marker panel development guidelines were established. Clamp efficiency was identified as a quantitative parameter for protocol optimization. The LNA-clamp-PCR is a robust, fast and cost-saving technique which needs low labor input. Therefore the method is adequate for enriching point mutated gene fragments in a diagnostic assay for the detection of early colon cancer stages. In addition LNA-clamp-PCR can be applied in other fields where rare sequence variations need to be detected in the presence of high wild-type DNA background.

T1  - Ökonomische, soziale und räumliche Folgen der saisonalen Arbeitsmigration im Herkunftsgebiet : am Beispiel der Region Konin (Polen)
T1  - Economic, social and spatial consequences of seasonal migration in the place of origin – case study : Konin (Poland)
N2  - Die vorliegende Arbeit basiert auf Forschungen in den Jahren 2007-2009. Sie betrachtet die saisonale Arbeitsmigration aus der polnischen Region Konin, wo die Arbeitsmigration aus ökonomischen Gründen, wie auch in ähnlich strukturierten Gebieten Polens, eine lange Tradition hat, die bis ins 19. Jahrhundert zurückgeht. Sie wird die saisonale Migration ins Ausland mit den ökonomischen, sozialen und räumlichen Auswirkungen aus der Perspektive des Einzelnen und seiner unmittelbaren Umgebung, aber auch der Gesellschaft und Herkunftsgebiet der Migranten betrachtet.
N2  - Mobility for economic reasons is treated in science primarily from the perspective of permanent resettlement. However, other varieties of migration are more and more often studied. This paper deals with the seasonal migration for economic reasons, which is an important area of migration undertaken for economic reasons. Seasonal migration, which leads to crossing the country borders, in the literature is called the Transnational Migration. Unlike international migration, which is usually connected with a permanent settling in the target area, the concept of Transnational migration describes the situation, in which migrants return to their place of origin and do not give it up as their main residence, but every time they travel to another country to get employed. As a research area of this work, the Konin region was chosen, because - in comparison with other regions in Poland - the phenomenon of a very high level of seasonal migration was observed there. Seasonal labor migration is a long tradition that goes back to 19. century here and in other Polish regions with similar structure. From the results of conducted in 2007−2009 research, some general facts can be drawn. Due to the seasonal work abroad, a seasonal migrant can increase their and their family’s standard of living. If the cost of living in the place of seasonal work is higher than in the place of origin, the profit of such visits is obviously higher if the family of a seasonal worker remains in the place of origin. This leads to the geographic division bet389 ween the place of working and place of permanent residence. Higher wages can be determined at the level of benefits to both personal and societal level. On the other hand, both forprofit workers and society in dealing with this phenomenon, costs cannot be ignored. This paper considers the pros and cons of seasonal paid work, both from the perspective of individuals and their surroundings, and the consequences for society and region of origin of the employee. This paper is considering economic, social and spatial consequences, each time at the macro and micro levels. The study was based primarily on interviews with several respondents and experts in the subject of Polish and German migrations for profit.

T1  - Entscheidung in Potsdam : ein dokumentarischer Bericht über den Einsatz der Atombombe
N2  - Im Potsdamer Stadtteil Babelsberg gab der Präsident der USA, Harry S. Truman, am 24. Juli 1945 den folgenschweren Befehl, die ersten Atombomben über Japan abzuwerfen. Bis zu diesem Tag war die Nutzung der Kernenergie eine von Forschern lediglich erdachte Möglichkeit. Mit Trumans Befehl wurde sie zur schrecklichen Wirklichkeit. Es begann eine neue Ära der Menschheit – das Atomzeitalter.

T1  - Sprachen in mobilisierten Kulturen : Aspekte der Migrationslinguistik
N2  - Thematische Schwerpunkte des Sammelbandes bilden die Inhalte und die Ziele in der Erforschung und Analyse von Migrationsprozessen und die daraus resultierenden Situationen von Sprachkontakt und Kulturtransfer in Europa und Übersee. Neben der thematischen Einführung in die Migrationslinguistik widmet sich der Band den migrationsbedingten Formen des Sprachkontaktes und der Sprachverwendung in Nordamerika sowie verschiedenen Sprachdynamiken in Europa. Auch der sprachliche Integrationsdruck zwischen Asien und Lateinamerika wird in diesem Band thematisiert. Neben Beiträgen von bekannten Migrationslinguisten wie Georges Lüdi (Universität Basel) und Hermann Haller (City University, New York) finden sich theoretische und deskriptive Ansätze zu Sprachkontakt, Sprachwandel und Sprachverfall infolge von Migration aus der Perspektive verschiedener Einzelphilologien. Mit Beiträgen von Lena Busse, Elizabeth Couper-Kuhlen, Hermann Haller, Friederike Kern, Georges Lüdi, Isolde Pfaff, Elton Prifti, Claudia Schlaak, Margret Selting, Thomas Stehl, Lars Steinicke und Maria Wilke.
N2  - The collected volume Sprachen in mobilisierten Kulturen: Aspekte der Migrationslinguistik comprises various articles that deal with the investigation and analysis of migrational processes and situations of language contact and cultural transfer that result from these processes in Europe and overseas. The volume gives a thematic introduction to the notion of linguistic migration and discusses various forms of language contact and language use in Northern America; it also addresses various forms of language dynamics in Europe. The pressure of linguistic integration between Asia and Latin America is also touched on in the collection. In addition to contributions by well-known migrational linguists, among them Georges Lüdi (University of Basel) and Hermann Haller (City University, New York), the volume also includes theoretical and descriptive treatments of language contact, language change and language loss as the result of migration from the perspective of various single philologies. Contributions are by Lena Busse, Elizabeth Couper-Kuhlen, Hermann Haller, Friederike Kern, Georges Lüdi, Isolde Pfaff, Elton Prifti, Claudia Schlaak, Margret Selting, Thomas Stehl, Lars Steinicke and Maria Wilke.

T1  - Harmonisierung von Lehren und Lernen mit der ‚doc.post‘ (document of commitment)
T1  - On adjusting teaching and learning with ‚doc.post‘ (‘document of commitment’)
JF  - Brandenburgische Beiträge zur Hochschuldidaktik
N2  - Internationale Forschungsbefunde zu ‚Teaching in Higher Education’ konstatieren immer wieder eine Nicht-Übereinstimmung zwischen intentional angelegten Lehrinhalten und Lernzielen und tatsächlich hervorgebrachten Fähigkeiten. Sie legen eine formative Evaluation von akademischen Lehr-Lern-Angeboten nahe, um bereits im Verlauf einer Lehrveranstaltung auf etwaige Lernschwierigkeiten und –barrieren reagieren zu können. Das an deutschen Hochschulen gängige Repertoire sozial-wissenschaftlicher Evaluationsinstrumente fokussiert jedoch zumeist auf summative quantitative Verfahren, die weder den verschiedenen Formaten akademischer Lehre noch dem komplexen Interaktionsgeschehen in Lehr-Lern-Kontexten gerecht zu werden scheinen, indem sie auf die Abfrage studentischer Zufriedenheitsniveaus abstellen. Anliegen dieses Beitrages ist es daher, ein von der Verfasserin entwickeltes multifunktionales und metakognitiv angelegtes Lehr-Lern-Forschungsinstrument, die ‚doc.post’ vorzustellen, das sich insbesondere zur Ausbildung generischer Kompetenzen in verschiedenen universitären erziehungs- und kulturwissenschaftlichen Studiengängen bewährt hat. Die ‚doc.post’ eignet sich gleichermaßen als Evaluations- und Prüfungsinstrument sowie für weitergehende Forschungsaktivitäten, die Qualität der eigenen Lehre betreffend.
N2  - Research in Higher Education has shown that teaching and learning is actually not the same. Although we always have well-designed plans in teaching courses, students often do not acquire the needed and desired learning outcomes. Teaching does not automatically lead to a desired learning outcome. Searching for a solution of the described gap between teaching and learning I worked out a method called ‘doc.post,’ that serves both teaching and learning. It impacts teaching observation and evaluation and reveals students’ learning processes and insights at once. This paper is the first result of my ruminations on how to harmonize teaching and learning and consists of six parts. Before introducing the currently developed method ‘doc.post’, I have given a more general comment on academic teaching and the creation of ‘doc.post’ as a result of my own teaching and learning processes at universities. This is followed by few a words on the theoretical and analytical frame that ‘doc.post’ has been built on. I then explore how to use and when to apply the ‘doc.post’ in academic teaching and learning. Finally I summarize the extent of resources ‘doc.post’ requires and in which case it is worth using. If readers are interested in further details, there is additional information on practicing ‘doc.post’ aligned to empirical data at the very end of this paper.
