Welcome Marie-Pier and Meredith!

The Abrahms Lab is growing! This fall we will have two new grad students join us in the Center: Meredith HonigPenguin Camp Meredith is interested in how species interactions shape ecological communities and wildlife population dynamics, especially in the implications of global climate change on these processes. She received a BS in Wildlife and Conservation Biology from the University of California, Davis in 2020. Meredith’s previous research experiences have encompassed a wide variety of topics including shark social behavior, hummingbird disease ecology, and large carnivore conservation and management. Before coming to the University of Washington, she also conducted research on […]

Testing Technology with the Woodland Park Zoo

Since 2015, we have deployed automatic weighbridges to track the foraging success of Magellanic penguins at one of their largest breeding colonies – Punta Tombo, Argentina. These weighbridges weigh penguins noninvasively as they leave the nesting area to forage and when they return to feed their chicks. This helps us track whether these penguins are finding enough food for themselves and their chicks. With new fishing effort data made available with satellite technology, we are excited to start working on how fishing and ocean conditions affect penguin foraging.  After all of these years in the harsh Patagonian environment (high winds,

Updates from the Field: Tombo Jan-Feb 2024

We continued our Punta Tombo field season this winter with graduate student Erik Johansson, former undergrad lab member Chloe Rabinowitz, and program coordinator Kalyna Durbak staying on site from January 12 through February 21. Our goal for this trip was to attach GTA* and GPS tags on adult penguins who were actively feeding chicks in order to log their foraging trips. Since the tags did not actively transmit data, they had to be retrieved after about two weeks of use. The tags were deployed 41 times throughout the field work trip; 31 GTA deployments and 10 GPS deployments. Center researchers

A fearful scourge to the penguin colonies: Southern giant petrel (Macronectes giganteus) predation on living Magellanic penguins (Spheniscus magellanicus) may be more common than assumed

Authors: Dr. Ginger Rebstock and Dr. P Dee BoersmaJournal: Marine Ecology Press SeriesDOI: https://doi.org/10.3354/meps14476 Excerpt from abstract: Southern giant petrels (Macronectes giganteus) are important consumers that range across the oceans throughout the southern hemisphere […] Here we describe a predation attempt by a trio of southern giant petrels on a molting adult Magellanic penguin (Spheniscus magellanicus) at the large colony at Punta Tombo, Argentina […] We suggest that living penguins—both fledglings and adults—may constitute a more seasonally significant proportion of the giant petrel diet than previously assumed, and their capture may represent a specialized predation technique.

Hunting mode and habitat selection mediate the success of human hunters

Authors: Kaitlyn M. Gaynor, Alex McInturff, Briana L. Abrahms, Alison M. Smith & Justin S. BrasharesJournal: Movement EcologyDOI: https://doi.org/10.1186/s40462-024-00471-z Abstract Excerpt: “Our study indicates that hunters can successfully employ a diversity of harvest strategies, and that hunting success is mediated by the interacting effects of hunting mode and landscape features. Such results highlight the breadth of human hunting modes, even within a single hunting technique, and lend insight into the varied ways that humans exert predation pressure on wildlife.” Photo credit by FieldsportsChannel.tv – https://www.flickr.com/photos/fieldsportschannel/39148108202/, CC BY 2.0, https://commons.wikimedia.org/w/index.php?curid=82827895

Abrahms Lab featured in AppleTV’s “EarthSounds”

If you ever wondered how we use acoustic collars to gain insights into the daily lives of African wild dogs, watch the new nature documentary series EarthSounds on AppleTV! Dr. Briana Abrahms and postdoc Dr. Kasim Rafiq were scientific consultants on the show, while Dr. Rafiq’s and grad student Leigh West‘s research was featured in the episode “Listening to Our Planet” from minutes 16:31-23:20. Watch as Dr. Rafiq identifies wild dogs, deploys a collar, and listens to wild dog chatter in an effort to understand how climate change impacts endangered African carnivores.

Dr. Dee Boersma awarded Godman Salvin Prize

Dr. Dee Boersma received the British Ornithological Union’s Godman Salvin Prize on February 23, 2024, during the Pacific Seabird Group’s annual conference banquet. The Godman Salvin Prize is awarded by BOU Council to honor an individual’s distinguished ornithological work. Recent Godman Salvin Prize recipients include Professor Cao Lei (2023), Professor Nick Davies (2022) and Professor Theunis Piersma (2020). The Committee commended Dee’s excellence in scientific research, practical conservation, scientific monitoring, and dissemination of science for public awareness, noting in particular her devotion to documenting the myriad aspects of what makes penguin’s lives what they are. Congratulations Dee! Read the full,
