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…

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

Abrahms Lab, Papers /

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

Papers /

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…

A spatial capture–recapture model for group-living species

Papers /

Authors: Robert L. Emmet, Ben C. Augustine, Briana Abrahms, Lindsey N. Rich, Beth GardnerJournal: EcologyDOI: https://doi.org/10.1002/ecy.3576 From the abstract: “Spatial capture–recapture (SCR) has been used to model both individual and group density in group-living species, but modeling either individual-level or group-level detection results in different biases due to common characteristics of group-living species, such as highly cohesive movement or variation in group size […]
