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

Explaining the mechanisms underlying patterns of species diversity and composition in
riverine networks is challenging. Historically, community ecologists have conceived of …

Lotic environments contain a disproportionate amount of biodiversity given their relatively
small proportion of the worldwide landscape. We conducted a systematic literature search of …

American eel Anguilla rostrata abundances have undergone significant declines over the
last 50 years, and migration barriers have been recognized as a contributing cause. We …

Stream classifications are important for understanding stream ecosystem diversity while also
serving as tools for aquatic conservation and management. With current rates of land and …

Mining impacts on stream systems have historically been studied over small spatial scales,
yet investigations over large areas may be useful for characterizing mining as a regional …

Understanding how assemblages are structured in space and the factors promoting their
distributions is one of the main goals in Ecology, however, studies regarding the distribution …

Urbanization substantially changes the physicochemical and biological characteristics of
streams. The trajectory of negative effect is broadly similar around the world, but the nature …

Aquatic ecosystems face a variety of anthropogenic pressures, urging the development of
efficient biological indicators. In addition to local environmental conditions, the community …

Spatial variation in extinction and colonization is expected to influence community
composition over time. In stream fish communities, local species richness (alpha diversity) …
