As many of you are aware, science is in a state of turmoil in the United States. Recent efforts to drastically reduce government workforces and research funding for science will lead to many adverse consequences for Earth’s remaining natural ecosystems.

Tracing the genetics of pigment loss in maternity colonies of Townsend's Big-Eared bats, Corynorhinus townsendii

The anomaly was not linked to inbreeding or low genetic diversity, but patterns suggest some heritability in the trait.

Phenotype response for the invasive Petaurus notatus in Tasmania.

Petaurus notatus, introduced to Tasmania in the 1830s, has been linked to bird predation. Using geometric morphometrics, we found Tasmanian gliders have larger skulls with features linked to carnivory.
