📢New paper 📢

MS student Clara Dawson's 1st chapter is out!

Does increased habitat connectivity always increase wildlife-vehicle collision rates?

No!

We found nonlinear effects of connectivity on wildlife-vehicle collisions

Happy to share the first paper from my primary postdoc project @plos.org, "Wild Florida Mottled Ducks demonstrate strong heterogeneity in their humoral innate immune response." The amazing team of undergraduates from Yale and UCF absolutely made this happen. journals.plos.org/plosone/arti...
Wild Florida mottled ducks demonstrate strong heterogeneity in their humoral innate immune response
The Florida Mottled Duck (Anas fulvigula fulvigula) is a unique subspecies of waterfowl whose range is limited to peninsular Florida, USA. As an endemic subspecies, Florida Mottled Ducks face numerous...

Nature research paper: Bat genomes illuminate adaptations to viral tolerance and disease resistance

Bat genomes illuminate adaptations to viral tolerance and disease resistance - Nature
A systematic analysis of 115 mammalian genomes, including 10 new bat genomes, reveals prevalent positive selection in immune genes in bats and shows key adaptations in the antiviral gene ISG15 that aid disease resistance in bats, including to coronaviruses.
