Migratory Connectivity and Non‐Breeding Habitat Segregation Across Biogeographi...
Morera‐Pujol, Virginia; Catry, Paulo; Magalhães, Maria; Péron, Clara; Reyes‐González, José Manuel; Granadeiro, José Pedro; Militão, TeresaIn highly mobile species, Migratory Connectivity (MC) has relevant consequences in population dynamics, genetic mixing, conservation and management. Additionally, in colonially breeding species, the maintenance of the breeding geographical structure during the non‐breeding period, that is, a strong MC, can promote isolation and population divergence, which ultimately can affect the process of lineage sorting. I...
The BirdLife Seabird Tracking Database: 20 years of collaboration for marine co...
Carneiro, Ana P.B.; Dias, Maria P.; Clark, Bethany L.; Pearmain, Elizabeth J.; Handley, Jonathan; Hodgson, Amy R.; Croxall, John P.The BirdLife Seabird Tracking Database (STDB) was established in 2004 to collate tracking data to address the incidental mortality of seabirds in fisheries and to contribute to identification of sites at sea relevant to establishment of Marine Protected Areas. After 20 years, the STDB has grown to hold ca. 39 million locations for 168 species from >450 breeding sites. The STDB has become a powerful tool to supp...
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...

Methods to detect spatial biases in tracking studies caused by differential rep...
Morera‐Pujol, Virginia; Catry, Paulo Xavier; Magalhães, Maria; Péron, Clara; Reyes‐González, José Manuel; Granadeiro, José Pedro; Militão, TeresaAim: Over the last decades, the study of movement through tracking data has grown exceeding the expectations of movement ecologists. This has posed new challenges, specifically when using individual tracking data to infer higher-level distributions (e.g. population and species). Sources of variability such as individual site fidelity (ISF), environmental stochasticity over time, and space-use variability across...

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 ofmigratory marine species, including pelagic seabirds, is challenging because theirmovements 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. T...

A framework for mapping the distribution of seabirds by integrating tracking, d...
Carneiro, Ana Paula B.; Pearmain, Elizabeth J.; Oppel, Steffen; Clay, Thomas A.; Phillips, Richard A.; Bonnet‐Lebrun, Anne‐Sophie; Wanless, Ross M.1. The identification of geographic areas where the densities of animals are highest across their annual cycles is a crucial step in conservation planning. In marine environments, however, it can be particularly difficult to map the distribution of species, and the methods used are usually biased towards adults, neglecting the distribution of other life-history stages even though they can represent a substantia...
