The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Aim Our aim was to examine gracile capuchin (Cebus) and robust capuchin monkey
(Sapajus) diversification, with a focus on recent Sapajus expansion within Amazonia. We …

The database of the IUCN SSC Primate Specialist Group currently (December 2023)
registers 218 species and subspecies of Neotropical primates in 24 genera and five families …

Aim Parapatric distributional patterns can arise from abiotic or biotic factors, or from
dispersal barriers. Climate change can potentially affect parapatry by changing species' …

Capuchin monkeys are currently represented by four species of Cebus and eight of Sapajus.
This group is taxonomically complex and several questions still need to be clarified. In the …

The high biological diversity of tropical forests has been attributed to various biogeographic
mechanisms promoting diversification. Among these, the riverine barrier hypothesis …

Differential phenotypic characteristics for taxonomic diagnosis purposes are well determined
in the genus Saimiri (squirrel monkey). However, data on its reproductive characteristics are …

Of the 19 currently recognized species of Sylvilagus Gray, 1867, 15 inhabit North America,
and only 5 are recognized in South America: S. brasiliensis Linnaeus, 1758 (throughout …

Background Past climatological events and contemporary geophysical barriers shape the
distribution, population genetic structure, and evolutionary history of many organisms. The …
