World African Wild Dog Day

Abrahms Lab, News /

Happy World African Wild Dog Day! While most people know the Center for Ecosystem Sentinels for our work on penguins, we also research African Wild Dogs. In fact, Dr. Kasim Rafiq and graduate students Leigh West and Marie-Pier Poulin are just returning from Botswana right now! As usual, they worked alongside our collaborators from Botswana Predator Conservation over the summer.

Increasing environmental variability inhibits evolutionary rescue in a long-lived vertebrate

Papers /

Authors: T. J. Clark-Wolf, P. Dee Boersma, Floriane Plard, Ginger A. Rebstock, and Briana AbrahmsJournal: PNASDOI: https://doi.org/10.1073/pnas.2406314121 “Using a multidecadal dataset on Magellanic penguins, we show that despite strong selection on body size, some environmental conditions favored larger bodies, and others favored smaller bodies, thus preventing consistent evolution in one direction or the other […] Such findings highlight that fluctuating

PENGUINS: Natural History and Conservation

Boersma Lab /

Published over 10 years ago, Penguins: Natural History and Conservation is still considered the publication about penguins. UW PressBookshop.comAmazon.com Penguins, among the most delightful creatures in the world, are also among the most vulnerable. The fragile status of most penguin populations today mirrors the troubled condition of the southern oceans, as well as larger marine conservation problems: climate change, pollution,

Authors: Stephanie Dodson, William K. Oestreich, Matthew S. Savoca, Elliott L. Hazen, Steven J. Bograd, John P. Ryan, Jerome Fiechter & Briana AbrahmsJournal: Scientific ReportsDOI: https://doi.org/10.1038/s41598-024-65827-2 “Social information is predicted to enhance the quality of animals’ migratory decisions in dynamic ecosystems, but the relative benefits of social information in the long-range movements of marine megafauna are unknown. In particular, whether

Spatial match-mismatch between predators and prey under climate change

Papers /

Authors: Gemma Carroll, Briana Abrahms, Stephanie Brodie & Megan A. Cimino Journal: Nature Ecology and Evolution DOI: https://doi.org/10.1038/s41559-024-02454-0 “Climate change is driving a rapid redistribution of life on Earth. Variability in the rates, magnitudes and directions of species’ shifts can alter spatial overlap between predators and prey, with the potential to decouple trophic interactions. Although phenological mismatches between predator requirements

World Ocean Day 2024

News /

Don’t know how to celebrate World Ocean Day this year? We have a few ideas: This year’s World Ocean Day theme this year is “One Ocean. One Climate. One Future.” One of Dee’s BIOL 305 students, Giovanna Esquivel, created this powerful PSA reminding us how our actions impact our world. Whether you’ve never been to the ocean or you go
