Zonula adherens junctions separate a smooth peripheral surface, the equivalent of the basolateral surface in other epithelial cells, from the central surface (cong apical surface). The latter consists of the microvillar rhabdomere and the juxtarhabdomeric domain, a nonmicrovillar area between the rhabdomere and the zonulae adherens. The distribution of Na/K-ATPase over these domains was examined by immunocytochemical, developmental, and genetic approaches. Immunofluorescence and immunogold labeling of adult compound eyes reveal that the distribution of Na/ K-ATPase is concentrated at the peripheral surface in the photoreceptors R1-R6, but extends over the juxtarhabdomeric domain to the rhabdomere in the photoreceptors R7/R8. Developmental analysis demonstrates further that Na/K-ATPase is localized over the entire plasma membrane in all photoreceptors in early pupal eyes. Redistribution of Na/K-ATPase in R1- R6 occurs at about 78\% of pupal life, coinciding with the onset of Rh1-rhodopsin expression on the central surface of these cells. Despite the essential role of Rh1 in structural development and intracellular trafficking, Rh1 mutations do not affect the distribution of Na/K-ATPase. These results suggest that Na/K-ATPase and rhodopsin are involved in distinct intracellular localization mechanisms, which are maintained independent of each other.}, language = {en} } @article{WoelflTittelZippeletal.2000, author = {W{\"o}lfl, S. and Tittel, J{\"o}rg and Zippel, Barbara and Kringel, R.}, title = {Occurrence of an algal mass development in an acidic (pH 2.5), iron and aluminium-rich coal mining pond}, year = {2000}, language = {en} } @article{WiesnerSalmikangasAuerbachetal.2000, author = {Wiesner, Sebastian and Salmikangas, Paula and Auerbach, Daniel and Himmel, Mirko and Kempa, Stefan and Hayes, Kathrin and Pacholsky, Dirk and Taivainen, Anu and Schr{\"o}der, Rolf and Carpen, Olli and F{\"u}rst, Dieter Oswald}, title = {Indications for a novel muscular dystrophy pathway : gamma-filamin, the muscle-specific filamin isoform, intgeracts with myotilin}, year = {2000}, language = {en} } @article{WiegandJeltsch2000, author = {Wiegand, T. and Jeltsch, Florian}, title = {Long-term dynamics in arid and semi-arid ecosystems : synthesis of a workshop}, year = {2000}, language = {en} } @article{WiegandWardThulkeetal.2000, author = {Wiegand, K. and Ward, D. and Thulke, Hans-Hermann and Jeltsch, Florian}, title = {From snap-shot information to long-term population dynamics of Acacias by a simulation model}, year = {2000}, language = {en} } @article{WiegandSchmidtJeltschetal.2000, author = {Wiegand, K. and Schmidt, H. and Jeltsch, Florian and Ward, D.}, title = {Linking a spatially-explicit model of acacias to GIS and remotely-sensed data}, year = {2000}, language = {en} } @article{WiegandJeltschWard2000, author = {Wiegand, K. and Jeltsch, Florian and Ward, D.}, title = {Do spatial effects play a role in the spatial distribution of desert dwelling Acacias?}, year = {2000}, language = {en} } @article{WeithoffLorkeWalz2000, author = {Weithoff, Guntram and Lorke, Andreas and Walz, Norbert}, title = {Effects of water-column mixing on bacteria, phytoplankton, and rotifers under different levels of herbivory in a shallow eutrophic lake}, year = {2000}, abstract = {Water column mixing is known to have a decisive impact on plankton communities. The underlying mechanisms depend on the size and depth of the water body, the nutrient status, and the plankton community structure and they are well understood for shallow polymictic and deep stratified lakes. Two consecutive mixing events of similar intensity under different levels of herbivory were performed in enclosures in a shallow, but periodically stratified, eutrophic lake, in order to investigate the effects of water column mixing on bacteria abundance, phytoplankton abundance and diversity, and rotifer abundance and fecundity. When herbivory by filter-feeding zooplankton was low, water column mixing provoking a substantial nutrient input into the euphotic zone, led to an intense net increase of bacteria and phytoplankton biomass. Phytoplankton diversity was lower in the mixed enclosures than in the undisturbed ones owing to the larger contribution of a few fast-growing species. After the second mixing event at high biomass of filter-feeding crustaceans, the increase of phytoplankton biomass was lower than after the first mixing, and diversity remained unchanged as the enhanced growth of small fast-growing was prevented by zooplankton grazing. Bacteria abundance did not increase after the second mixing, when cladoceran biomass was high. Rotifer fecundity indicated a transmission of the phytoplankton response to the next trophic level. Our results suggest that water column mixing in shallow eutrophic lakes with periodic stratification has a strong effect on the plankton community by enhanced nutrient availability rather than resuspension or reduced light availability. This fuels the basis of the classic and microbial food chain via enhanced phytoplankton and bacteria growth, but the effects on biomass may be dampened by high levels of herbivory.}, language = {en} } @article{WeberJeltsch2000, author = {Weber, Gisela and Jeltsch, Florian}, title = {Long-term impacts of livestock herbivory on herbaceous and woody vegetation in semiarid savannas}, year = {2000}, language = {en} } @article{WarsinkeBenkertScheller2000, author = {Warsinke, Axel and Benkert, Alexander and Scheller, Frieder W.}, title = {Electrochemical immunoassays}, year = {2000}, language = {en} } @phdthesis{Wanner2000, author = {Wanner, Susanne C.}, title = {Transport, retention, and turnover of particulate organic matter (POM) in the lowland River Spree (Germany)}, pages = {101 S.}, year = {2000}, language = {en} } @article{WalzUkhanovZimmermann2000, author = {Walz, Bernd and Ukhanov, Kyrill and Zimmermann, Bernhard}, title = {Actions of neomycin on electrical light responses : Ca2+ release and intracellular Ca2+ changes in photoreceptors of the honeybee drone}, issn = {0340-7594}, year = {2000}, language = {en} } @article{WalzUkhanov2000, author = {Walz, Bernd and Ukhanov, Kyrill}, title = {Light-dependent repetitive Ca2+ spikes induced by extracellular application of neumycin in honeybee drone photoreceptors}, issn = {0340-7594}, year = {2000}, language = {en} } @article{Vater2000, author = {Vater, Marianne}, title = {Auditory brainstem processing in bats}, isbn = {3-527-27587- 8}, year = {2000}, language = {en} } @article{Vater2000, author = {Vater, Marianne}, title = {Cochlear specializations in bats}, isbn = {3-527-27587-8}, year = {2000}, language = {en} } @article{Vater2000, author = {Vater, Marianne}, title = {Cochlear specializations in bats}, isbn = {3-527-27587-8}, year = {2000}, language = {en} } @article{Vater2000, author = {Vater, Marianne}, title = {Evolutionary plasticity and ontogeny of the bat cochlea.}, isbn = {0-521-62632-3}, year = {2000}, language = {en} } @article{VanDerVenBartschGauteletal.2000, author = {VanDerVen, Peter F.

There is now a broad consensus that the balance between negative and positive interactions should shift along environmental gradients, with competition prevailing under environmentally benign conditions and positive interactions dominating under harsh conditions. A commonly cited example of the importance of facilitation in harsh environments is the preference of desert annual plants for the areas under the canopy of shrubs. The recognition of apparently positive effects of desert shrubs on annuals, however, has been mostly based on density measurements, while fitness parameters of the understory plants have been ignored. Also, the temporal consistency of such effects has not been previously tested. Based on conceptual ideas about the balance between interference and facilitation, we predicted that positive effects of the shrubs on the understory should dominate in dry years, while in favorable years, negative effects would be stronger. We tested our hypothesis by measuring the direction and magnitude of the shrub effect on demographic responses of four desert annual plant species during four consecutive seasons of differing rainfall. The results contradicted our initial hypothesis. Depending on the species, the effect of the shrubs shifted from either negative to neutral or from neutral to positive with increasing annual rainfall. However, this trend was stronger for the effect of shrubs on plant reproductive success than on their densities. Our data highlight the importance of measuring fitness parameters in studies of plant-plant interactions. We suggest that the negative effects of shrubs on plant fitness were due to rainfall interception, while positive effects were related to increased nutrient availability beneath shrubs. However, the mechanisms by which the shrubs and annuals interact can only be resolved using an experimental approach. Our results contradict previous hypotheses about the relative importance of positive and negative interactions along environmental gradients.

In deserts, local-scale differences in environmental productivity may be caused by the presence of shrubs, which represent a favorable habitat for annual populations within a nutrient-poor matrix.

Such negative indirect effects have so far been ignored in studies about plant-plant interactions. We tested our hypothesis by measuring seedling survival and fecundity of four abundant annual plant species with and without neighbors in open areas and under shrub canopies in a sandy desert area. Our findings did not indicate indirect negative effects of shrubs on their understory annuals. Sensitivity to the presence of neighbors varied between species and surprisingly, the species with the smallest seeds was the only one which was not negatively affected by the presence of neighbors. In contrast to our hypothesis, there was no difference between the habitat types shrubs and openings in absolute and relative competition intensity.

Temperature-sensitive folding (tsf) mutations decrease folding yields at high temperature, but hardly affect thermal stability of the native trimeric structure when assembled at low temperature. Global suppressor (su) mutations mitigate this phenotype. Virtually all of these mutations are located in the central domain of tailspike, a large parallel beta-helix. We modified tailspike by rational single amino acid replacements at three sites in order to investigate the influence of mutations of two types: (1) mutations expected to cause a tsf phenotype by increasing the side-chain volume of a core residue, and (2) mutations in a similar structural context as two of the four known su mutations, which have been suggested to stabilize folding intermediates and the native structure by the release of backbone strain, an effect well known for residues that are primarily evolved for function and not for stability or folding of the protein. Analysis of folding yields, refolding kinetics and thermal denaturation kinetics in vitro show that the tsf phenotype can indeed be produced rationally by increasing the volume of side chains in the beta-helix core. The high-resolution crystal structure of mutant T326F proves that structural rearrangements only take place in the remarkably plastic lumen of the beta-helix, leaving the arrangement of the hydrogen-bonded backbone and thus the surface of the protein unaffected. This supports the notion that changes in the stability of an intermediate, in which the beta-helix domain is largely formed, are the essential mechanism by which tsf mutations affect tailspike folding. A rational design of su mutants, on the other hand, appears to be more difficult. The exchange of two residues in the active site expected to lead to a drastic release of steric strain neither enhanced the folding properties nor the stability of tailspike. Apparently, side-chain interactions in these cases overcompensate for backbone strain, illustrating the extreme optimization of the tailspike protein for conformational stability. The result exemplifies the view arising from the statistical analysis of the distribution of backbone dihedral angles in known three-dimensional protein structures that the adoption of straight phi/psi angles other than the most favorable ones is often caused by side-chain interactions.}, language = {en} } @article{SchroederVanDerVenWarloetal.2000, author = {Schr{\"o}der, Rolf and VanDerVen, Peter F.

It involves the combination of autotrophy and heterotrophy in varying degrees. Many phytoflagellate species ingest bacteria as a means of obtaining nutrients for photosynthesis or for supplementing their carbon budget under light limitation. Ciliates either sequester the plastids of their algal prey or harbour endosymbiotic algae. In the saline lakes of the Vestfold Hills and in Lakes Hoare and Fryxell in the McMurdo Dry Valleys the dominant phytoflagellates ingest bacteria, and there is evidence to suggest that during the winter months they lack chlorophyll and may become entirely heterotrophic. In Lake Fryxell phagotrophic pyhtoflagellates (cryptophytes) made a significant impact on bacterial production, removing up to 13\% of the bacterial biomass day-1. These cryptophytes suffered predation from Plagiocampa (a ciliate), which appears to harbour them for a significant period before digesting them. We suspect that this may be equivalent to an intermediate stage in the evolution of mixotrophy. A significant number of the planktonic ciliates in Antarctic lakes were mixotrophic. The final evolutionary end point is the situation seen in Mesodinium rubrum, which now relies entirely on its cryptophycean endosymbiont and no longer ingests food. Mesodinium is the dominant ciliate in many of the saline lakes of the Vestfold Hills, which are of marine origin. It can reach abundances in excess of 60,000l-1 in Ace Lake, This ciliate is a ubiquitous member of the marine plankton worldwide and has successfully adapted to the lacustrine environment in Antarctica. The evidence suggests that among the survival strategies seen in Antarctic lake plankton, mixotrophy plays and important role among a number of the dominant protozoan species.}, language = {en} } @article{LaybournParryBellRoberts2000, author = {Laybourn-Parry, J. and Bell, Elanor M. and Roberts, E.

The response of the nanoflagellates to temperature differed between lakes in eastern and western Antarctica. In Ace Lake the available bacterial food resources had little impact on growth rate, while temperature imposed an impact, whereas in Lake Hoare increased bacterial food resources elicited an increase in growth rate. However, the incorporation of published data from across Antarctica showed that temperature had the greater effect, but that growth is probably controlled by a suite of factors not solely related to bacterial food resources and temperature. Dinoflagellates had relatively high specific growth rates (0.0057-0.384 h(-1)), which were comparable to Antarctic lake ciliates and to dinoflagellates from warmer, lower latitude locations. Temperature did not appear to impose any significant impact on growth rates. Mixotrophic cryptophytes in Lake Hoare had lower specific growth rates than HNAN (0.0029-0.0059 h(-1) and 0.0056-0.0127 h(-1), respectively). They showed a marked seasonal variation in growth rate, which was probably related to photosynthetically active radiation under the ice at different depths in the water column. Ciliates' growth rates showed no relationship between food supply and mean cell volume, but did show a response to temperature. Specific growth rates ranged between 0.0033 and 0.150 h(-1) for heterotrophic ciliates, 0.0143 h(-1) for a mixotrophic Plagiocampa species and 0.0075 h(-1) for the entirely autotrophic ciliate, Mesodinium rubrum.

The growth rates of an Chlamydomonas- isolate from acidic mining lakes were assessed by measuring cell densities under pure autotrophic and heterotrophic conditions (with glucose as organic C-source) and showed values of 0.74 and 0.40, respectively.}, language = {en} } @phdthesis{BenkertSchellerSchoessleretal.2000, author = {Benkert, Alexander and Scheller, Frieder W. and Sch{\"o}ssler, W. and Micheel, Burkhard and Warsinke, Axel}, title = {Size exclusion redox-labeled immunoassay (SERI) : a new format for homogeneous amperometric creatinine determination}, year = {2000}, language = {en} } @article{BeckerGetzin2000, author = {Becker, Thorsten and Getzin, Stephan}, title = {The fairy circles of Kaokoland (North-West-Namibia) : origin, distribution, and characteristics}, year = {2000}, language = {en} } @article{BaumannArltRoemmlingetal.2000, author = {Baumann, Otto and Arlt, Kathleen and R{\"o}mmling, Katja and Goller, Helmut and Walz, Bernd}, title = {Characterization of an extremely motile cellular network in the rotifer Asplanchna spp. : structure, kinetics, and cytoskeleton}, year = {2000}, language = {en} } @article{BaumannArltRoemmlingetal.2000, author = {Baumann, Otto and Arlt, Kathleen and R{\"o}mmling, Katja and Goller, Helmut and Walz, Bernd}, title = {Characterization of an extremely motile cellular network in the rotifer Asplanchna : Structure, kinetics and the cytoskeleton}, year = {2000}, language = {en} } @article{Baumann2000, author = {Baumann, Otto}, title = {Distribution of ryanodine receptor Ca2+ channels in insect photoreceptor cells}, year = {2000}, language = {en} }
