Increasing ambient temperatures trigger shifts in activity patterns and temporal partitioning in a large carnivore guild

Authors: Kasim Rafiq, Neil R. Jordan, Krystyna Golabek, John W. McNutt, Alan Wilsonand, Briana AbrahmsJournal: Proceedings of the Royal Society: Biological SciencesDOI: https://doi.org/10.1098/rspb.2023.1938 Shifts in species’ interactions are implicated as an important proximate cause underpinning climate-change-related extinction. However, there is little empirical evidence on the pathways through which climate conditions, such as ambient temperature, impact community dynamics… Photo credit: Krystyna Jordan

Field updates: Argentina, September 2023

Written by Dr. Dee Boersma The ongoing pinniped (seals and walruses) die-off on Peninsula Valdés is catastrophic. Our contacts in Argentina–two local veterinarians (Marci Uhart and Ralph Vanstreels), and Claudia Campagna of WCS–tell us that hundreds and potentially thousands of sea lions and elephant seals have died. Avian flu (more widely known as bird flu) has devastated seabird populations throughout the world, but this is the first time it has reached Chile and Argentina. Over a million chickens were killed just in Peru to try and stop its spread. A few sea lions and one elephant seal tested positive for

Field updates: Botswana, summer 2023

Written by Leigh West African wild dogs are very social animals, living in groups called packs. Wild dog packs have a dominant male and female, and it is this dominant pair that breeds each year to produce litters of pups. Packs of wild dogs are very cooperative, hunting and raising their young together. Two of the wild dogs that the Abrahms Lab collared this summer, Fossey and Cloud, belong to newly formed packs with a very interesting backstory. The dominant male of Marula pack, Sepupa, was killed last summer. This led the pack’s dominant female to leave her home range,

Using the power of models to protect whales from possible ship-strikes

Written by Dr. Anna Nisi We have been building cutting-edge models of species distributions for four great whale species – blue, fin, sperm, and humpback whales. One key threat to the great whales is collisions with shipping vessels, and identifying places where ship-strike risk is high is essential for informing mitigation actions like vessel slow-downs. Our next step is to overlay whale distributions with maps of global shipping traffic, to prioritize these areas for conservation action and help protect these vulnerable species. The results of our work will inform expanding vessel slow-down programs to encompass larger areas and reduce whale
