Climate presses and pulses mediate the decline of a migratory predator

Authors: T. J. Clark-Wolf, P. Dee Boersma, Ginger A. Rebstock, and Briana AbrahmsJournal: Proceedings of the National Academy of SciencesDOI: 10.1073/pnas.2209821120 Long-term climate changes and extreme climate events differentially impact animal populations, yet whether and why these processes may act synergistically or antagonistically remains unknown…

Should I stay or should I go: factors influencing mate retention and divorce in a colonial seabird

Authors: Eric L. Wagner, Caroline D. Cappello, P. Dee BoersmaJournal: Animal BehaviourDOI: 10.1016/j.anbehav.2022.08.002 Divorce among serially monogamous birds can lead to increased reproductive success if an individual obtains a higher-quality mate or nest site, or it can lead to lower reproductive success due to lack of pair experience or reduced breeding opportunities…

Long-term, climate-driven phenological shift in a tropical large carnivore

Authors: Briana Abrahms, Kasim Rafiq, Neil R. Jordan, and J. W. McNuttJournal: Proceedings of the National Academy of SciencesDOI:10.1073/pnas.2121667119 Understanding the degree to which animals are shifting their phenology to track optimal conditions as the climate changes is essential to predicting ecological responses to global change…

Site fidelity increases reproductive success by increasing foraging efficiency in a marine predator

Authors: Ginger A Rebstock, Briana Abrams, P. Dee BoersmaJournal: Behavioral EcologyDOI: 10.1093/beheco/arac052 Seabirds must find food efficiently in the dynamic ocean environment to succeed at raising chicks. In theory, site familiarity, gained by prior experience in a place, should increase foraging efficiency when prey is predictable, and translate into increased reproductive success, though this is difficult to test empirically…

Acoustic signature reveals blue whales tune life-history transitions to oceanographic conditions

Authors: William K. Oestreich, Briana Abrahms, Megan F. McKenna, Jeremy A. Goldbogen, Larry B. Crowder, John P. RyanJournal: British Ecological SocietyDOI: 10.1111/1365-2435.14013 Matching the timing of life-history transitions with ecosystem phenology is critical for the survival of many species, especially those undertaking long-distance migrations…

Unprecedented heat mortality of Magellanic Penguins

Authors: Katie Holt and Dee BoersmaJournal: Ornithological ApplicationsDOI: https://doi.org/10.1093/ornithapp/duab052 Abstract excerpt: Extreme weather events are becoming more frequent and severe, leading to an increase in direct, adverse thermoregulatory impacts on wildlife. Here, we document an unprecedented, single-day, heat-related mortality event of Magellanic Penguins (Spheniscus magellanicus) at Punta Tombo, Chubut Province, Argentina, one of the largest breeding colonies for this species.
