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 albatrosses and large petrels. Populations from every country made extensive use of the high seas, indicating the stake each country has in the management of biodiversity in international waters. We quantified the links among national populations of these threatened seabirds and the regional fisheries management organizations (RFMOs) which regulate fishing in the high seas. This work makes explicit the relative responsibilities that each country and RFMO has for the management of shared biodiversity, providing invaluable information for the conservation and management of migratory species in the marine realm.
- Multispecies tracking reveals a major seabird hotspot in the North AtlanticPublication .

R.; Thompson, Paul; Thórarinsson, Thorkell L.; Bemmelen, Rob S.A.; Wanless, Sarah; Zino, Francis; Dias, Maria P.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 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. This revealed a major hotspot associated with a discrete area of the subpolar frontal zone, used annually by 2.9–5 million seabirds from ≥56 colonies in the Atlantic: the first time this magnitude of seabird concentrations has been documented in the high seas. The hotspot is temporally stable and amenable to site-based conservation and is under consideration as a marine protected area by the OSPAR Commission. Protection could help mitigate current and future threats facing species in the area. Overall, our approach provides an exemplar data-driven pathway for future conservation efforts on the high seas.
- Spatial scales of marine conservation management for breeding seabirdsPublication .

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 provide guidance on whether conservation management approaches should be tailored for taxonomic groups with different movement characteristics. Seabird tracking data were synthesised from 5419 adult breeding individuals of 52 species in ten families that were collected in the Atlantic Ocean basin between 1998 and 2017. Two key aspects of spatial distribution were quantified, namely how far seabirds ranged from their colony, and to what extent individuals from the same colony used the same areas at sea. There was evidence for substantial differences in patterns of space-use among the ten studied seabird families, indicating that several alternative conservation management approaches are needed. Several species exhibited large foraging ranges and little aggregation at sea, indicating that area-based conservation solutions would have to be extremely large to adequately protect such species. The results highlight that short-ranging and aggregating species such as cormorants, auks, some penguins, and gulls would benefit from conservation approaches at relatively small spatial scales during their breeding season. However, improved regulation of fisheries, bycatch, pollution and other threats over large spatial scales will be needed for wide-ranging and dispersed species such as albatrosses, petrels, storm petrels and frigatebirds.
- Tracking data and the conservation of the high seas: Opportunities and challengesPublication . Davies, Tammy; Campos, Bruna; Hazin, Carolina; Dunn, Daniel; Gjerde, Kristina M.; Johnson, David E.; Dias, Maria P.1. Biologging technology is rapidly advancing—scientists are obtaining data on movement and behaviour for a range of species, more accurately than ever before. With this information, it is possible to understand more about important areas and their connections across the open ocean including the high seas, beyond national jurisdictions. But an absence of a global governance framework has so far hindered a coordinated approach to conservation action on the high seas. 2. We showcase a candidate high seas MPA in the Northeast Atlantic identified primarily from seabird tracking data and being taken forward under a regional process: the North Atlantic Current and Evlanov Seamount (NACES) MPA, under the OSPAR Commission. It provides a unique case study to learn about the intricacies of implementation when applying tracking information for conservation. From this, we identify the facilitating conditions and challenges faced from identification to designation and highlight actionable opportunities for future area-based management of the high seas that will be made possible under a new agreement. 3. Policy implications. The North Atlantic Current and Evlanov Seamount (NACES) MPA demonstrates the power of translating tracking data into usable geospatial knowledge to inform conservation and policy and provides an exemplar for a data-driven approach to high seas conservation that can become a reality under the forthcoming governance framework (under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (known as the BBNJ Agreement)). This new agreement presents a unique conservation opportunity both for the application of tracking data to conservation outcomes and for the protection of migratory species.
