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...
Measuring trends in extinction risk: a review of two decades of development and...
Butchart, Stuart H. M.; Akçakaya, H. Resit; Berryman, Alex J.; Brooks, Thomas M.; Burfield, Ian J.; Chanson, Janice; Dias, Maria P.; Donaldson, John S.The Red List Index (RLI) is an indicator of the average extinction risk of groups of species and reflects trends in this through time. It is calculated from the number of species in each category on the IUCN Red List of Threatened Species, with trends influenced by the number moving between categories when reassessed owing to genuine improvement or deterioration in status. The global RLI is aggregated across mu...
Establishing bio-logging data collections as dynamic archives of animal life on...
Davidson, Sarah C.; Cagnacci, Francesca; Newman, Peggy; Dettki, Holger; Urbano, Ferdinando; Desmet, Peter; Bajona, Lenore; Bryant, EdmundRapid growth in bio-logging—the use of animal-borne electronic tags to document the movements, behaviour, physiology and environments of wildlife—offers opportunities to mitigate biodiversity threats and expand digital natural history archives. Here we present a vision to achieve such benefits by accounting for the heterogeneity inherent to bio-logging data and the concerns of those who collect and use them. Fi...
Site‐level connectivity identified from multiple sources of movement data to in...
Beal, Martin; Nightingale, Josh; Belo, João R.; Batey, Chris; Belting, Heinrich; Bocher, Pierrick; Burgess, Malcolm; Craft, Taylor B.; Crockford, NicolaMigratory birds depend on a suite of sites across their annual cycles, making them vulnerable to a wide variety of anthropogenic pressures. Current area-based conservation measures have been found inadequate to safeguard migratory birds, in part due to a lack of consideration for the connectivity between sites mediated by the movements of individuals. To address this issue, we develop a network analysis integra...
Fixed-plot monitoring as a tool to assess population trends of underground nest...
Catry, Paulo; Dias, Maria P.; Menezes, Dília; Oliveira, Paulo; Lopes, Daniel; Alho, Maria; Campioni, Letizia; Catry, Teresa; Gatt, Marie ClaireMedium to small petrels that mostly nest in burrows or crevices represent a large fraction of the world’s seabirds, yet their population trends are largely unknown. This lack of knowledge, which has implications for conservation planning, results mostly from methodological difficulties and from the approaches that have been used for their monitoring. Here, we present the surveying scheme created to monitor Cory...
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...
Quantifying annual spatial consistency in chick-rearing seabirds to inform impo...
Beal, Martin; Catry, Paulo Xavier; Phillips, Richard A.; Oppel, Steffen; Arnould, John P. Y.; Bogdanova, Maria I.; Bolton, Mark; Carneiro, Ana P. B.Animal tracking has afforded insights into patterns of space use in numerous species and thereby informed areabased conservation planning. A crucial consideration when estimating spatial distributions from tracking data is whether the sample of tracked animals is representative of the wider population. However, it may also be important to track animals in multiple years to capture changes in distribution in res...

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...
Co‐developing guidance for conservation: An example for seabirds in the North‐E...
Häkkinen, Henry; Taylor, Nigel G.; Pettorelli, Nathalie; Sutherland, William J.; Aldará, Jón; Anker‐Nilssen, Tycho; Aulert, ChristopheConservation guidance—an authoritative source of information and recommendations explicitly supporting decision-making and action regarding nature conservation—represents an important tool to communicate evidence-based advice to conservation actors. Given the rapidly increasing pressure that climate change poses to biodiversity, producing accessible, well-informed guidance on how to best manage the impacts and ...
