The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Variations in Movement and Habitat Selection by Eurasian Curlew at Two Important Sites in Europe Throughout Winter

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This study aimed to determine if the space and habitats used by Eurasian curlews (Numenius arquata) were influenced by their wintering site and stage. A total of 62 curlews were equipped with GPS‐GSM tags at two major wintering sites in Europe and their home ranges and foraging habitat selection were compared according to three wintering stages ...

No Evidence That Nest Cover Shapes Incubation Schedules in a Mediterranean Shorebird Population

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We investigated how nest cover is associated to incubation behaviour in a Mediterranean biparental population of Kentish Plovers using 24‐h video recordings from 24 nests with variable nest cover that ranged from fully open (0% coverage) to complete coverage (100%).

Adult survival of Arctic terns in the Canadian High Arctic

open access: yesPolar Research, 2018
Arctic tern (Sterna paradisaea) populations are thought to be in decline across much of their range. For long-lived seabirds, determining adult survival rates is key to understanding current population trends and predicting trajectories.

Ecological implications and lessons from high pathogenicity avian influenza H5N1 2.3.4.4b in Antarctica

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.
