The upper rio Paraná basin drains the most developed and environmentally degraded
region in South America: the Brazilian southeast. While it is one of the most well-known …

High‐throughput sequencing approaches have enabled characterizations of the community
composition of numerous gut microbial communities, which in turn has enhanced interest in …

Habitat degradation leads to biodiversity loss and concomitant changes in ecosystem
processes. Tropical river floodplains are highly threatened by land cover changes and …

In response to temporal changes in the quality and availability of food resources, consumers

Abstract The Neotropical catfish family Loricariidae is the fifth most species-rich vertebrate
family on Earth, with over 800 valid species. The Hypostominae is its most species-rich …

Land-cover change often shifts the distribution of biomass in animal communities. However,
the effects of land-cover changes on functional diversity remain poorly understood for many …

A key factor for estimates of assimilation of resources and trophic position based on stable
isotope data is the trophic discrimination factor (TDF). TDFs are assumed based on literature …

Aim Little is known about factors affecting the elevational and longitudinal zonation of
tropical Andean stream communities. We investigated epilithon, macroinvertebrate and fish …
