The “Mexclapique” Girardinichthys viviparus, is a goodeid endemic to the Valley of Mexico basin. This species is endangered following habitat alterations due to urbanization and p…

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…

We provide new records of Neogale frenata and Potos flavus, two carnivores with elusive behaviors that are challenging to observe in their natural habitats. Through direct records…
