It is typically at the species level where the responses of organisms to natural environmental
gradients are the most clearly visible. However, due to the fact that many organismal groups …

Environmental filtering and spatial structuring are important ecological processes for the
generation and maintenance of biodiversity. However, the relative importance of these …

I examined patterns in stream macroinvertebrate assemblage structure and assemblage–
environment relationships at four taxonomic levels (ie species, genus, family, and order) and …

Studies of biodiversity and ecosystem function need to consider the identification level that
accurately describes the functional diversity of communities, in terms of their biological traits …

Many studies have shown traditional species diversity indices to perform poorly in
discriminating anthropogenic influences on biodiversity. By contrast, in marine systems …

Large-scale diversity patterns in relationship to environmental factors at multiple spatial
scales have been well-studied for many taxonomic groups; however, freshwater ecosystems …

Streams are naturally hierarchical systems, and their biota are affected by factors effective at
regional to local scales. However, there have been only a few attempts to quantify variation …

Metacommunity ecology emphasizes that community structure and diversity are not only
determined by local environmental conditions through environmental filtering, but also by …

1. The structure of lotic macroinvertebrate communities may be strongly influenced by land‐
use practices within catchments. However, the relative magnitude of influence on the …

Although our knowledge of the spatial distribution of stream organisms has been increasing
rapidly in the last decades, there is still little consensus about trait-based variability of …
