We present the first comprehensive taxonomic revision and review the biology of the
olingos, the endemic Neotropical procyonid genus Bassaricyon, based on most specimens …

Studies on Neotropical phylogeography have largely focused on lowland organisms.
Because lowland and highland biotas have different histories and are likely affected by …

Morphologically cryptic species act as a wild card when it comes to biodiversity assessments
and conservation, with the capacity to dramatically alter our understanding of the biological …

We studied the phylogeny, biogeography, and diversification of suboscine passerines in the
genus Scytalopus (Rhinocryptidae), a widespread, species-rich, and taxonomically …

Overall morphological similarity and intrapopulation variation of morphological features
make species identification in cryptic species complexes challenging. In such cases …
