Written by Dr. Kasim Rafiq In June 2024, postdoctoral researcher Dr. Kasim Rafiq and PhD candidate Leigh West from Dr. Briana Abrahms‘ lab returned to Wild Dog Camp in the Okavango Delta and were joined by Briana’s new PhD student Marie-Pier Poulin. The team successfully deployed six new tracking collars on African wild dogs, including in two brand new packs, […]

Congratulations to Leigh West, Dr. Abrahms’s graduate student, who just recently published her first paper as lead author. Her research article, “Droughts reshape apex predator space use and intraguild overlap,” was published in the Journal of Animal Ecology on October 4th, and also serves as the second chapter of her dissertation. This is an exciting milestone for Leigh as she

In July 2024, Dr. Dee Boersma and Dr. Caroline Cappello traveled to the Galápagos Islands for a penguin expedition unlike any they’d experienced before. Since 2010, CES has collaborated with Galápagos National Park and conservationist Godfrey Merlen to visit penguin breeding areas and conduct research. After Godfrey’s passing in 2023, CES—with heavy hearts but optimism for the future—sought a new

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.
