Recent technological and conceptual advances have improved our ability to assess the causes and consequences of individual movement, and led to the emergence of the new field of 'movement ecology'. Here, we outline how movement ecology can contribute to the broad field of biodiversity research, i.e. the study of processes and patterns of life among and across different scales, from genes to ecosystems, and we propose a conceptual framework linking these hitherto largely separated fields of research. Our framework builds on the concept of movement ecology for individuals, and demonstrates its importance for linking individual organismal movement with biodiversity. First, organismal movements can provide 'mobile links' between habitats or ecosystems, thereby connecting resources, genes, and processes among otherwise separate locations. Understanding these mobile links and their impact on biodiversity will be facilitated by movement ecology, because mobile links can be created by different modes of movement (i.e., foraging, dispersal, migration) that relate to different spatiotemporal scales and have differential effects on biodiversity. Second, organismal movements can also mediate coexistence in communities, through 'equalizing' and 'stabilizing' mechanisms. This novel integrated framework provides a conceptual starting point for a better understanding of biodiversity dynamics in light of individual movement and space-use behavior across spatiotemporal scales. By illustrating this framework with examples, we argue that the integration of movement ecology and biodiversity research will also enhance our ability to conserve diversity at the genetic, species, and ecosystem levels.}, language = {en} } @misc{HelfertWarschburger2013, author = {Helfert, Susanne and Warschburger, Petra}, title = {The face of appearance-related social pressure}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-401155}, pages = {11}, year = {2013}, abstract = {Background Appearance-related social pressure plays an important role in the development of a negative body image and self-esteem as well as severe mental disorders during adolescence (e.g. eating disorders, depression). Identifying who is particularly affected by social pressure can improve targeted prevention and intervention, but findings have either been lacking or controversial. Thus the aim of this study is to provide a detailed picture of gender, weight, and age-related variations in the perception of appearance-related social pressure by peers and parents. Methods 1112 German students between grades 7 and 9 (mean age: M = 13.38, SD = .81) filled in the Appearance-Related Social Pressure Questionnaire (German: FASD), which considers different sources (peers, parents) as well as various kinds of social pressure (e.g. teasing, modeling, encouragement). Results Girls were more affected by peer pressure, while gender differences in parental pressure seemed negligible. Main effects of grade-level suggested a particular increase in indirect peer pressure (e.g. appearance-related school and class norms) from early to middle adolescence. Boys and girls with higher BMI were particularly affected by peer teasing and exclusion as well as by parental encouragement to control weight and shape. Conclusion The results suggest that preventive efforts targeting body concerns and disordered eating should bring up the topic of appearance pressure in a school-based context and should strengthen those adolescents who are particularly at risk - in our study, girls and adolescents with higher weight status. Early adolescence and school transition appear to be crucial periods for these efforts. Moreover, the comprehensive assessment of appearance-related social pressure appears to be a fruitful way to further explore social risk-factors in the development of a negative body image.}, language = {en} } @misc{WolffBrand2013, author = {Wolff, Wanja and Brand, Ralf}, title = {Subjective stressors in school and their relation to neuroenhancement}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-401131}, pages = {6}, year = {2013}, abstract = {Background: The use of psychoactive substances to neuroenhance cognitive performance is prevalent. Neuroenhancement (NE) in everyday life and doping in sport might rest on similar attitudinal representations, and both behaviors can be theoretically modeled by comparable means-to-end relations (substance-performance). A behavioral (not substance-based) definition of NE is proposed, with assumed functionality as its core component. It is empirically tested whether different NE variants (lifestyle drug, prescription drug, and illicit substance) can be regressed to school stressors. Findings: Participants were 519 students (25.8 +/- 8.4 years old, 73.1\% female). Logistic regressions indicate that a modified doping attitude scale can predict all three NE variants. Multiple NE substance abuse was frequent. Overwhelming demands in school were associated with lifestyle and prescription drug NE. Conclusions: Researchers should be sensitive for probable structural similarities between enhancement in everyday life and sport and systematically explore where findings from one domain can be adapted for the other. Policy makers should be aware that students might misperceive NE as an acceptable means of coping with stress in school, and help to form societal sensitivity for the topic of NE among our younger ones in general.}, language = {en} } @misc{SchwarteBrustSteupetal.2013, author = {Schwarte, Sandra and Brust, Henrike and Steup, Martin and Tiedemann, Ralph}, title = {Intraspecific sequence variation and differential expression in starch synthase genes of Arabidopsis thaliana}, series = {BMC Research Notes}, journal = {BMC Research Notes}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-401128}, pages = {14}, year = {2013}, abstract = {Background Natural accessions of Arabidopsis thaliana are a well-known system to measure levels of intraspecific genetic variation. Leaf starch content correlates negatively with biomass. Starch is synthesized by the coordinated action of many (iso)enzymes. Quantitatively dominant is the repetitive transfer of glucosyl residues to the non-reducing ends of α-glucans as mediated by starch synthases. In the genome of A. thaliana, there are five classes of starch synthases, designated as soluble starch synthases (SSI, SSII, SSIII, and SSIV) and granule-bound synthase (GBSS). Each class is represented by a single gene. The five genes are homologous in functional domains due to their common origin, but have evolved individual features as well. Here, we analyze the extent of genetic variation in these fundamental protein classes as well as possible functional implications on transcript and protein levels. Findings Intraspecific sequence variation of the five starch synthases was determined by sequencing the entire loci including promoter regions from 30 worldwide distributed accessions of A. thaliana. In all genes, a considerable number of nucleotide polymorphisms was observed, both in non-coding and coding regions, and several amino acid substitutions were identified in functional domains. Furthermore, promoters possess numerous polymorphisms in potentially regulatory cis-acting regions. By realtime experiments performed with selected accessions, we demonstrate that DNA sequence divergence correlates with significant differences in transcript levels. Conclusions Except for AtSSII, all starch synthase classes clustered into two or three groups of haplotypes, respectively. Significant difference in transcript levels among haplotype clusters in AtSSIV provides evidence for cis-regulation. By contrast, no such correlation was found for AtSSI, AtSSII, AtSSIII, and AtGBSS, suggesting trans-regulation. The expression data presented here point to a regulation by common trans-regulatory transcription factors which ensures a coordinated action of the products of these four genes during starch granule biosynthesis. The apparent cis-regulation of AtSSIV might be related to its role in the initiation of de novo biosynthesis of granules.}, language = {en} } @misc{PavesiTiedemannDeMatthaeisetal.2013, author = {Pavesi, Laura and Tiedemann, Ralph and De Matthaeis, Elvira and Ketmaier, Valerio}, title = {Genetic connectivity between land and sea}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-401110}, pages = {19}, year = {2013}, abstract = {Introduction: We examined patterns of genetic divergence in 26 Mediterranean populations of the semi-terrestrial beachflea Orchestia montagui using mitochondrial (cytochrome oxidase subunit I), microsatellite (eight loci) and allozymic data. The species typically forms large populations within heaps of dead seagrass leaves stranded on beaches at the waterfront. We adopted a hierarchical geographic sampling to unravel population structure in a species living at the sea-land transition and, hence, likely subjected to dramatically contrasting forces. Results: Mitochondrial DNA showed historical phylogeographic breaks among Adriatic, Ionian and the remaining basins (Tyrrhenian, Western and Eastern Mediterranean Sea) likely caused by the geological and climatic changes of the Pleistocene. Microsatellites (and to a lesser extent allozymes) detected a further subdivision between and within the Western Mediterranean and the Tyrrhenian Sea due to present-day processes. A pattern of isolation by distance was not detected in any of the analyzed data set. Conclusions: We conclude that the population structure of O. montagui is the result of the interplay of two contrasting forces that act on the species population genetic structure. On one hand, the species semi-terrestrial life style would tend to determine the onset of local differences. On the other hand, these differences are partially counter-balanced by passive movements of migrants via rafting on heaps of dead seagrass leaves across sites by sea surface currents. Approximate Bayesian Computations support dispersal at sea as prevalent over terrestrial regionalism.}, language = {en} } @article{Scheffler2013, author = {Scheffler, Christiane}, title = {Biological age}, series = {Auxology : Studying Human Growth and Development}, journal = {Auxology : Studying Human Growth and Development}, editor = {Hermanussen, Michael}, publisher = {Schweizerbart Science Publishers}, address = {Stuttgart}, isbn = {978-3-510-65278-5}, pages = {44 -- 47}, year = {2013}, language = {en} } @article{BalderjahnPeyerPaulssen2013, author = {Balderjahn, Ingo and Peyer, Mathias and Paulssen, Marcel}, title = {Consciousness for fair consumption : conceptualization, scale development and empirical validation}, series = {International Journal of Consumer Studies}, volume = {37}, journal = {International Journal of Consumer Studies}, number = {5}, publisher = {Wiley-Blackwell}, address = {Oxford}, issn = {1470-6431}, doi = {10.1111/ijcs.12030}, pages = {546 -- 555}, year = {2013}, abstract = {Sustainable consumption means that consumers act in an environmentally and socially responsible manner. Compared with the vast amount of studies concerning environmentally conscious consumer behaviour, relatively little is known about socially conscious consumption. The present paper focuses on fair consumption as an important aspect of social consumption. In our study, consciousness for fair consumption (CFC) is defined as a latent disposition of consumers to prefer products that are produced and traded in compliance with fair labour and business practices. A scale to measure CFC was conceptualized and tested in three independent empirical studies. Two studies were conducted at European universities (2010 and 2012) and used 352 and 362 undergraduate business students respectively. The third study, conducted in 2011, used 141 employees at a European university. The results confirmed the reliability and validity of the new CFC scale across samples. While being moderately related to other aspects of sustainable consumption such as ecological concern and moral reasoning, CFC was significantly distinct from those concepts. Most importantly, it was established that the CFC, as measured by the new CFC scale, is a strong determinant of consumption of fair trade products that has been neglected in existing research.}, language = {en} } @article{BalderjahnBuerkeKirchgeorgetal.2013, author = {Balderjahn, Ingo and Buerke, Anja and Kirchgeorg, Manfred and Peyer, Mathias and Seegebarth, Barbara and Wiedmann, Klaus-Peter}, title = {Consciousness for sustainable consumption : scale development and new insights in the economic dimension of consumers' sustainability}, series = {AMS review : official publication of the Academy of Marketing Scienc}, volume = {3}, journal = {AMS review : official publication of the Academy of Marketing Scienc}, number = {4}, publisher = {Springer}, address = {New York}, issn = {1869-814X}, doi = {10.1007/s13162-013-0057-6}, pages = {181 -- 192}, year = {2013}, abstract = {The "triple bottom line" concept (planet, people, and profit) represents an important guideline for the sustainable, hence future-oriented, development of societies and for the behaviors of all societal members.

HK620TSP binds hexasaccharide fragments with low affinity, but single amino acid exchanges generated a set of high-affinity mutants with submicromolar dissociation constants. Isothermal titration calorimetry showed that only small amounts of heat were released upon complex formation via a large number of direct and solvent-mediated hydrogen bonds between carbohydrate and protein. At room temperature, association was both enthalpy- and entropy-driven emphasizing major solvent rearrangements upon complex formation. Crystal structure analysis showed identical protein and sugar conformers in the TSP complexes regardless of their hexasaccharide affinity. Only in one case, a TSP mutant bound a different hexasaccharide conformer. The extended sugar binding site could be dissected in two regions: first, a hydrophobic pocket at the reducing end with minor affinity contributions. Access to this site could be blocked by a single aspartate to asparagine exchange without major loss in hexasaccharide affinity. Second, a region where the specific exchange of glutamate for glutamine created a site for an additional water molecule. Side-chain rearrangements upon sugar binding led to desolvation and additional hydrogen bonding which define this region of the binding site as the high-affinity scaffold.}, language = {en} } @misc{ArnisonBibbBierbaumetal.2013, author = {Arnison, Paul G. and Bibb, Mervyn J. and Bierbaum, Gabriele and Bowers, Albert A. and Bugni, Tim S. and Bulaj, Grzegorz and Camarero, Julio A. and Campopiano, Dominic J. and Challis, Gregory L. and Clardy, Jon and Cotter, Paul D. and Craik, David J. and Dawson, Michael and Dittmann-Th{\"u}nemann, Elke and Donadio, Stefano and Dorrestein, Pieter C. and Entian, Karl-Dieter and Fischbach, Michael A. and Garavelli, John S. and Goeransson, Ulf and Gruber, Christian W. and Haft, Daniel H. and Hemscheidt, Thomas K. and Hertweck, Christian and Hill, Colin and Horswill, Alexander R. and Jaspars, Marcel and Kelly, Wendy L. and Klinman, Judith P. and Kuipers, Oscar P. and Link, A.

In contrast, for higher concentrations and/or higher target temperatures, i.e. deep temperature jumps, intermicellar bridges dominate the growth. Eventually, in all cases, the clusters coagulate which results in macroscopic phase separation.
