1. Cyanobacteria of the Wadden Sea: seasonality and sediment influence on community composition

Author:

Subject:
Lyngbya; community structure; ecosystems; environmental factors; high-throughput nucleotide sequencing; littoral zone; niches; ribosomal RNA; sediments; spring; summer; temporal variation; Germany; North Sea
Abstract:
... Tidal flats are extremely dynamic habitats in several environmental parameters, which enforces severe selection on their microbial inhabitants. Despite good knowledge of the species present, little is known about the temporal dynamics of their communities. Aim of the study was the investigation of cyanobacterial populations in intertidal flats of the German Wadden Sea and their seasonal- and sedim ...

Asellus aquaticus; Chara; Chironomidae; Dikerogammarus villosus; Dreissena polymorpha; Ephemeroptera; Potamopyrgus antipodarum; community structure; habitat preferences; invasive species; macroinvertebrates; multidimensional scaling; snails; species diversity; temporal variation; Germany; Lake Constance
Abstract:
... The composition of benthic macroinvertebrate communities is influenced by a variety of factors, including the introduction of invasive species. However, only few analyses of factors influencing benthic community structure exist, especially those including invasive species. Our aim was to examine the importance of biotic factors on spatial and temporal variations in the benthic community within one ...

Subject:
Planktothrix rubescens; climate change; community structure; ecosystems; lakes; models; phytoplankton; Germany
Abstract:
... A number of modelling results suggested thermocline shifts as a consequence of global climate change in stratifying lakes. Abundance and composition of the phytoplankton assemblage is strongly affected by the stratification patterns, and therefore, change in the thermocline position might have a substantial effect on this community or even on the whole lake ecosystem. In this study, thermocline de ...

Subject:
alpha-Proteobacteria; climate change; community structure; drought; enzyme activity; extracellular enzymes; microbial communities; organic matter; prokaryotic cells; sediments; streams; temperate zones; Germany
Abstract:
... Intermittent flow of headwaters occurs with increasing frequency in temperate regions over last decades. Here, we assessed the effects of rewetting process on benthic prokaryotic communities from the Breitenbach (Hesse, Germany) for 10 days following experimental drought of different duration and intensity, by measuring the abundance of selected prokaryotic groups and potential extracellular enzym ...

5. Relevance of abiotic criteria used in German lake typology for macroinvertebrate fauna

Subject:
calcium; climate; community structure; ecoregions; fauna; geology; lakes; macroinvertebrates; multivariate analysis; seasonal variation; species diversity; watersheds; Germany
Abstract:
... For lake characterisation, top-down typologies are mostly used throughout Europe, including type criteria such as climate, lake area, catchment geology and conductivity. In Germany, a lake typology was applied comprising ecoregion, calcium concentration, Schindler’s ratio, stratification type and residence time. However, the relevance of these criteria for the macroinvertebrate fauna has not been ...

Abstract:
... (1) A study of the metazoan community occurring in water-filled tree-holes in southern Germany has been performed to determine the relationships among the key species of arthropods found within the community and a range of structural, physical and chemical factors, using multivariate techniques. (2) Four animal species were sufficiently common to allow identification of the preferred environments ...
