Papers /

Authors: Stephanie Dodson, William K. Oestreich, Matthew S. Savoca, Elliott L. Hazen, Steven J. Bograd, John P. Ryan, Jerome Fiechter & Briana AbrahmsJournal: Scientific ReportsDOI: https://doi.org/10.1038/s41598-024-65827-2 “Social information is predicted to enhance the quality of animals’ migratory decisions in dynamic ecosystems, but the relative benefits of social information in the long-range movements of marine megafauna are unknown. In particular, whether […]

Spatial match-mismatch between predators and prey under climate change

Papers /

Authors: Gemma Carroll, Briana Abrahms, Stephanie Brodie & Megan A. Cimino Journal: Nature Ecology and Evolution DOI: https://doi.org/10.1038/s41559-024-02454-0 “Climate change is driving a rapid redistribution of life on Earth. Variability in the rates, magnitudes and directions of species’ shifts can alter spatial overlap between predators and prey, with the potential to decouple trophic interactions. Although phenological mismatches between predator requirements

The capacity of sentinel species to detect changes in environmental conditions and ecosystem structure

Papers /

Authors: T. J. Clark-Wolf, Katie A. Holt, Erik Johansson, Anna C. Nisi, Kasim Rafiq, Leigh West, P. Dee Boersma, Elliott L. Hazen, Sue E. Moore, Briana AbrahmsJournal: Journal of Applied EcologyDOI: https://doi.org/10.1111/1365-2664.14669 “A major obstacle to preventing and reversing biodiversity loss in the Anthropocene lies in the scarcity of tools and data for monitoring the health and trajectory of ecosystems. Sentinel species can provide insight into unobserved ecosystem change,

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

Hunting mode and habitat selection mediate the success of human hunters

Abrahms Lab, Papers /

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

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

Papers /

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

Changing course: Relocating commercial tanker lanes significantly reduces threat of chronic oiling for a top marine predator

Papers /

Metadata Authors: Eric L. Wagner, Esteban Frere, P. Dee BoersmaJournal: Marine Pollution BulletinDOI: 10.1016/j.marpolbul.2023.11 Summary Summary written by Sofia Denkovski Argentinian oil and effects on seabirds Surveys from 1982-1990 suggested more than 40,000 penguins died per year in Chubut and Santa Cruz from chronic oiling. This was hypothesized to be due to the colonies’ proximity to oil centers and shipping
