Global assessment of marine plastic exposure risk for oceanic birds
Clark, Bethany L.; Carneiro, Ana P. B.; Pearmain, Elizabeth J.; Rouyer, Marie-Morgane; Clay, Thomas A.; Cowger, Win; Phillips, Richard A; Manica, AndreaPlastic pollution is distributed patchily around the world's oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and m...

Global political responsibility for the conservation of albatrosses and large p...
Beal, Martin; Dias, Maria P.; Phillips, Richard A.; Oppel, Steffen; Hazin, Carolina; Pearmain, Elizabeth J.; Adams, Josh; Anderson, David J.Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of national jurisdictions and high seas areas for 39 species of albatross...
Multispecies tracking reveals a major seabird hotspot in the North Atlantic
Davies, Tammy E.; Carneiro, Ana P.B.; Tarzia, Marguerite; Wakefield, Ewan; Hennicke, Janos C.; Frederiksen, Morten; Hansen, Erpur Snær; Campos, BrunaThe conservation of migratory marine species, including pelagic seabirds, is challenging because their movements span vast distances frequently beyond national jurisdictions. Here, we aim to identify important aggregations of seabirds in the North Atlantic to inform ongoing regional conservation efforts. Using tracking, phenology, and population data, we mapped the abundance and diversity of 21 seabird species....
Seabird migration strategies: Flight budgets, diel activity patterns, and lunar...
Bonnet-Lebrun, Anne-Sophie; Dias, Maria P.; Phillips, Richard; Granadeiro, José P.; Brooke, M. de L.; Chastel, Olivier; Clay, Thomas A.; Fayet, AnnetteEvery year, billions of birds undertake extensive migrations between breeding and nonbreeding areas, facing challenges that require behavioural adjustments, particularly to flight timing and duration. Such adjustments in daily activity patterns and the influence of extrinsic factors (e.g., environmental conditions, moonlight) have received much more research attention in terrestrial than marine migrants. Taking...

Important At-Sea areas of colonial breeding marine predators on the Southern Pa...
Baylis, Matthew; Tierney, Megan; Orben, Rachael; Evans, Victoria Warwick; Wakefield, Ewan; Grecian, William James; Trathan, Phil; Reisinger, Ryan R.The Patagonian Shelf Large Marine Ecosystem supports high levels of biodiversity and endemism and is one of the most productive marine ecosystems in the world. Despite the important role marine predators play in structuring the ecosystems, areas of high diversity where multiple predators congregate remains poorly known on the Patagonian Shelf. Here, we used biotelemetry and biologging tags to track the movement...
Effect of breeding performance on the distribution and activity budgets of a pr...
Ponchon, Aurore; Cornulier, Thomas; Hedd, April; Granadeiro, José Pedro; Catry, PauloPelagic seabirds breeding at high latitudes generally split their annual cycle between reproduction, migration, and wintering. During the breeding season, they are constrained in their foraging range due to reproduction while during winter months, and they often undertake long-distance migrations. Black-browed albatrosses (Thalassarche melanophris) nesting in the Falkland archipelago remain within 700 km from t...
Global phenological insensitivity to shifting ocean temperatures among seabirds
Keogan, Katharine; Daunt, Francis; Wanless, Sarah; Phillips, Richard A.; Walling, Craig A.; Agnew, Philippa; Ainley, David G.; Anker-Nilssen, TychoReproductive timing in many taxa plays a key role in determining breeding productivity1, and is often sensitive to climatic conditions2. Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey3. This is of particular concern for highertrophic- level organisms, whose ...
Spatial scales of marine conservation management for breeding seabirds
Oppel, Steffen; Bolton, Mark; Carneiro, Ana Paula B.; Dias, Maria P.; Green, Jonathan A.; Masello, Juan F.; Phillips, Richard A.; Owen, EllieKnowing the spatial scales at which effective management can be implemented is fundamental for conservation planning. This is especially important for mobile species, which can be exposed to threats across large areas, but the space use requirements of different species can vary to an extent that might render some management approaches inefficient. Here the space use patterns of seabirds were examined to provid...
