Integrative morphometric and molecular analyses reveal possible genetic contamination of silver catfish populations of the genus Rhamdia in Neotropical River basins

open access: yesJournal of Fish Biology, EarlyView.
Abstract Rhamdia quelen, Rhamdia branneri and Rhamdia voulezi are morphologically similar species that, until recently, were considered synonymous. Although R. quelen has wide distribution in the Neotropical region, R. branneri and R. voulezi are sympatric and endemic species of the Iguaçu River basin.

Investigating the behavioral responses of nektonic and benthic tadpoles elicited by the presence of a predatory nektonic fish

open access: yesJournal of Zoology, EarlyView.
Different defensive strategies are used by tadpoles to avoid or escape from predators, and it is possible that differences in the microhabitat of prey and predators influence the defensive strategies used by tadpoles. Therefore, we experimentally tested whether the presence of a nektonic fish predator (Oreochromis niloticus) reduces the time of ...

Use of synanthropic roosts by bats in Europe and North America

open access: yesMammal Review, EarlyView.
Although bats often use buildings for roosting, the true proportion of their populations roosting in buildings is not known. Based on review of radio‐tracking studies, we found that 2× more species and 17× times higher proportion of populations use SRs in Europe than in North America, respectively.
