Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Immersion patterns alone can predict vessel following by albatrosses

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 1831-1843, August 2025.
We demonstrate that seabird immersion patterns alone can detect high‐risk seabird‐vessel interactions, even in the absence of locational data for both seabirds and vessels. Our approach could allow for more comprehensive seabird bycatch risk assessments that quantify previously hidden seabird‐vessel interactions, such as those involving migratory life ...

Conservation‐focused mapping of avian migratory routes using a pan‐European automated telemetry network

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Accelerated biodiversity loss has destabilized functional links within and between ecosystems. Species that cross different ecosystems during migration between breeding and nonbreeding sites are particularly sensitive to global change because they are exposed to various, often ecosystem‐specific, threats.

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change

open access: yesGlobal Change Biology, Volume 30, Issue 7, July 2024.
This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...
