We provide a general compilation of the diversity and geographical distribution of
Amazonian fishes, updated to the end of 2018. Our database includes documented …

Landscape dynamics are widely thought to govern the tempo and mode of continental

Electroreception, the capacity to detect external underwater electric fields with specialised
receptors, is a phylogenetically widespread sensory modality in fishes and amphibians. In …

ABSTRACT Biogeography of Amazonian fishes (2,500 species in vastly disjunct lineages) is
complex and has so far been approached only partially. Here, we tackle the problem on the …

A cladistic biogeographical analysis was undertaken to identify the main events in the biotic
diversification of the terrestrial N eotropical biota. For the 36 animal and plant taxa analysed …

We herein analyse the history of the description of the freshwater fish fauna from three
drainages in one of the most densely collected areas of Brazil, and possibly of South …

Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and
endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under …
