Abstract Plastic 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 crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, highly threatened, cover vast distances during foraging migration. However, spatial overlap between petrels plastics poorly understood. Here we combine...
Abstract The 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 seabirds in the North Atlantic inform ongoing regional efforts. Using tracking, phenology, and population data, mapped abundance diversity 21 seabird species. This revealed a major hotspot associated with discrete area subpolar frontal zone, used annually by 2.9–5...

Sexual segregation in foraging occurs many animal species, resulting the partitioning of resources and reduction competition between males females, yet patterns drivers such are still poorly understood. We studied movements (GPS-tracking), habitat use (habitat modelling) trophic ecology (stable isotope analysis) female male Cory's shearwaters Calonectris borealis during mid chick-rearing period six consecutive breeding seasons (2010-2015). found a clear sexual years greater environmental...
This study examines blood mercury (Hg) concentrations in Calonectris sp. shearwaters from three colonies along the Atlantic and Mediterranean coasts of Iberian Peninsula (southwestern Europe), investigating their relationship with foraging ecology through GPS tracking stable isotopes (δ15N δ13C) data during breeding season. Hg levels exhibited a spatial gradient, increasing Ocean (1.8 ± 0.4 μg g-1 dw) towards Sea, Columbretes Islands (NW Mediterranean) showing highest (6.5 2.1 dw)....
Knowledge about sexual segregation and gender-specific, or indeed individual specialization, in marine organisms has improved considerably the past decade. In this context, we tested "Intersexual Competition Hypothesis" for penguins by investigating feeding ecology of Gentoo during their austral winter non-breeding season. We considered unusual environmental conditions (i.e. year 2009 had observations high sea surface air temperatures) comparison with long term average at Bird Island, South...
Niche segregation between similar species will result from an avoidance of competition but also environmental variability, including nowadays anthropogenic activities. Gulls are among the seabirds with greater behavioural plasticity, being highly opportunistic and feeding on a wide range prey, mostly origin. Here, we analysed blood feather stable isotopes combined pellet analysis to investigate niche partitioning Audouin's gull Larus audouinii yellow‐legged michahellis breeding in sympatry...
Abstract Fisheries produce large quantities of discards, an important resource for scavenging seabirds. However, a policy reform banning which is soon to be implemented within the EU, will impose food shortage upon scavengers, and it still largely unknown how scavengers behave. We studied diet (hard remains), trophic (stable isotope analysis), foraging (individual tracking) ecology two gull species breeding in sympatry: Audouin’s Larus audouinii (AG) yellow-legged michahellis (YLG), South...

Chemical pollution is a major threat to marine ecosystems, and top predators such as most shark species are extremely vulnerable being exposed accumulating contaminants metals persistent organic pollutants (POPs). This work aimed study the degree, composition, sources of contamination in blue (Prionace glauca) inhabiting Northeast Atlantic, well potential risk faced by human consumers. A total 60 sharks were sampled situ aboard fishing vessels, concentrations set POPs analysed various...
Individuals within populations can use different resources, leading to ecological segregation and niche variation. This could have direct impacts on the migratory strategy or breeding success, thus affecting overall population community dynamics and, ultimately, survival. In this study, we assessed inter-annual individual foraging ecology of an endemic highly threatened seabird species, Desertas petrel Pterodroma deserta, during non-breeding phases. We combined 54 annual tracks (26...
