Ecological opportunities and physical challenges of fast-water habitats have dramatically
shaped the evolution of freshwater fish lineages from a broad diversity of clades globally …

Summary 1 Interspecific niche differences have long been identified as a major explanation
for the occurrence of species‐rich communities. However, much fieldwork studying variation …

Deforestation is a primary driver of biodiversity change through habitat loss and
fragmentation. Stream biodiversity may not respond to deforestation in a simple linear …

Ecomorphological patterns of the fish assemblage from the upper Paraná River floodplain,
Brazil, were described and evaluated according to trophic (guilds), spatial (habitats) and …

Deforestation can modify stream habitat and the functional structure of fish assemblages.
The aims of this study were (a) to identify whether deforestation has a similar effect on local …

The subfamily Loricariinae belongs to the Neotropical mailed catfish family Loricariidae.
Members of Loricariinae are recognized by their long and flattened caudal peduncle and …
