Random encounter modelling as a viable method to estimate absolute abundance of reef fish

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 598-614, February 2026.
Abstract Remote underwater video (RUV) surveys are increasingly replacing diver‐based underwater visual censuses (UVCs) in fish ecology studies, especially on coral reefs. However, extracting reliable estimates of abundance or density from video footage is a major challenge, with most studies using a metric of relative abundance, MaxN (maximum number ...

A multiscale seasonal examination of the risk of harm to seabirds from vessels based on co‐occurrence in Alaskan waters

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Alaska's seascape supports globally significant seabird populations, including vulnerable and threatened species, and hosts economically important commercial fisheries and marine transportation corridors. Seasonal patterns of seabird movements and vessel traffic create a complex landscape of risk, defined as high levels of co‐occurrence ...

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 ...

Individual Variation in Philopatry Is Unrelated to Activity and Space Use in the Undulate Skate Raja undulata

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Consistent individual variation in fine‐scale movement traits is unrelated to movements occurring at larger spatio‐temporal scales in undulate skates (Raja undulata). ABSTRACT Individual variation in behavior is widespread in animals. Movement traits, which describe how individuals interact with their environment, can vary across a range of spatial and

Inferring activity patterns of aquatic animals from single‐receiver acoustic telemetry setups

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 12, Page 2931-2944, December 2025.
Abstract Acoustic telemetry has become an essential tool for studying activity patterns of animals in aquatic environments. Activity is typically recorded using transmitters with integrated sensors or dense receiver arrays for positional tracking. While effective, these approaches are financially and logistically expensive due to the need for advanced ...
