Tree cavities used as sleeping sites are a limited resource for arboreal mammals. The shared use of arboreal cavities as sleeping sites between Neotropical mammals is rarely obser…

In Mexico opossums are difficult to find, and much of their natural history, ecology, and behavior are unknown. Through photographic and visual records, we obtained data on the pr…

Herbivores obtain nutrients mostly from the vegetation they consume, but may obtain additional minerals during periods of nutritional stress by consuming bones (osteophagia), a be…

The diversity of the oryzomyine rat Mindomys (Cricetidae, Sigmodontinae, Oryzomyini), is doubled here with the description of a new species from the remote Cordillera de Kutukú (E…

Monitoring climate changes and habitat degradation in threatened species without negative impact to the populations can pose a considerable challenge. A rare chance to test the mo…

We report the first country record of Rhacophorus verrucopus Huang, 1983 from Myanmar, based on one specimen collected from Htamanthi Wildlife Sanctuary, Sagaing Division. Morphol…

Glinus is a small genus of Molluginaceae with 8–10 species mostly distributed in the tropics of the World. Its composition and evolutionary relationships were poorly studied. A ne…

Plectostoma is a micro land snail restricted to limestone outcrops in Southeast Asia. Plectostoma was previously classified as a subgenus of Opisthostoma because of the deviation …

We use a combination of cytochrome b sequence data and karyological evidence to confirm the presence of Mus indutus and Mus minutoides in Botswana. Our data include sampling from …

A new genus is proposed for the strikingly patterned African vespertilionid “Glauconycteris” superba Hayman, 1939 on the basis of cranial and external morphological comparisons. A…

Continuous improvements in the resolution of three-dimensional imaging have led to an increased application of these techniques in conventional taxonomic research in recent years.…
