Metacommunity ecology addresses the situation where sets of local communities are
connected by the dispersal of a number of potentially interacting species. Aquatic systems …

Most bioassessment programs rest on the assumption that species have different niches,
and that abiotic environmental conditions and changes therein determine community …

Relationships between traits of organisms and the structure of their metacommunities have
so far mainly been explored with meta‐analyses. We compared metacommunities of a wide …

The factors driving β-diversity (variation in community composition) yield insights into the
maintenance of biodiversity on the planet. Here we tested whether the mechanisms that …

The present review with focus on the last decade (2000–2010) aims to (i) collecting the
major hypotheses explaining freshwater biodiversity patterns,(ii) identifying the main …

The aim of this paper is to review literature on species diversity patterns of freshwater
organisms and underlying mechanisms at large spatial scales. 2. Some freshwater taxa (eg …

Aim To examine species and trait composition in stream diatoms along environmental,
climatic and spatial gradients and to ascertain if the use of different levels of biological …

Community ecologists and conservation biologists often work with data that are too sparse
for achieving reliable inference with species‐specific approaches. Here we explore the idea …

The estimation of the relative roles of environment, space, and their interactions in
structuring community composition is one of the central topics of community ecology. I …

Ecologists have long investigated why communities are composed of a few common species
and many rare species. Most studies relate rarity to either niche differentiation among …
