▪ Abstract Aquatic insects and other benthic invertebrates are the most widely used
organisms in freshwater biomonitoring of human impact. Because of the high monetary …

Current rates of climate change are unprecedented, and biological responses to these
changes have also been rapid at the levels of ecosystems, communities, and species. Most …

Aim Global‐scale studies are required to identify broad‐scale patterns in the distributions of
species, to evaluate the processes that determine diversity and to determine how similar or …

Aim We examined the relative contributions of spatial gradients and local environmental
conditions to macroinvertebrate assemblages of boreal headwater streams at three …

We examined the utility of using genera and families as surrogates of species-level
assemblage patterns. We assessed cross-taxonomic level congruence, as well as …

Summary 1 Multiscale determinants of diversity and the relationship between regional
(RSR) and local richness (LSR) have recently attracted increased attention, yet such studies …

The examination of correlates of diatom community structure has long been centred on local
environmental factors instead of broad-scale biogeographical factors largely because …

An important goal for community ecology is the characterization and prediction of changes in
community patterns along environmental gradients. We aimed to identify the major …

We developed a new Multimetric Index for stream assessment, which is mainly focussed on
the impact of hydromorphological degradation on the macroinvertebrate fauna. The index …

Aim Understanding variation in biodiversity typically requires consideration of factors
operating at different spatial scales. Recently, ecologists and biogeographers have …
