Vrba was right: Historical climate fragmentation, and not current climate, explains mammal biogeography

Global Change Biology, Volume 30, Issue 5, May 2024.
This study explores how past climate changes have influenced species distribution. We found that regions with more historical climate variation have more specialist species, while generalist species decrease. This effect is stronger than the link between current climate and species richness.

Meta‐analysis suggests that, for marine mammals, the risk of parasitism by anisakids changed between 1978 and 2015

Ecosphere, Volume 15, Issue 3, March 2024.
Abstract As gastrointestinal parasites affect the health of marine mammal species, they are a potentially consequential stressor. Although they are infrequently identified as a cause of mortality, gastrointestinal parasites could drive cryptic declines in individual fitness—including declines in nutritional status—by acting synergistically with other ...

Extinction risk of the world's freshwater mammals

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract The continued loss of freshwater habitats poses a significant threat to global biodiversity. We reviewed the extinction risk of 166 freshwater aquatic and semiaquatic mammals—a group rarely documented as a collective. We used the International Union for the Conservation of Nature Red List of Threatened Species categories as of December 2021 to

Study of the behavior of Amazonian manatee (Trichechus inunguis) in captivity (Puerto Nariño – Amazonas, Colombia)

Acta Biológica Colombiana, 2000
The behavior of the amazon manatee, which is classified as “vulnerable”, has been poorlystudied. This research constitutes the first ethological study of one Trichechus inunguis.
