Space use of polar bears (Ursus maritimus) in Davis Strait in relation to sea ice and harp seals (Pagophilus groenlandicus)

Arctic Science
Polar bears (Ursus maritimus Phipps, 1774) rely on seals as their primary prey, yet predator–prey spatial relationships are poorly understood. We examined the spatial relationship between Davis Strait polar bears and harp seals (Pagophilus groenlandicus ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, Volume 46, Issue 11, Page 4085-4098, November 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

At‐nest drone monitoring causes minimal behavioural disturbance in breeding Eurasian Curlew

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
Incubating Eurasian Curlew taken with DJI Mavic 3T optical camera at a height of 25 m. Drone‐based monitoring of breeding Curlew in lowland England caused minimal behavioural disturbance. Although incubating birds frequently looked up at the drone, displacement from the nest was rare, suggesting that drones can provide an effective low‐impact ...

Biodiversity isn't measured in tons: Making sense of nature in the context of sustainable agriculture

Ecological Applications, Volume 36, Issue 7, October 2026.
Abstract In this review, we articulate several important but often overlooked concepts, trends, and perspectives in the biodiversity monitoring space, specifically in the context of transforming agriculture and the wider food system. We describe the common approaches to biodiversity monitoring—those focused on species, communities, functions, habitats,

Can Competition‐Based Programs Promote Conservation in Agriculture? Evidence From the “Most Crop per Drop” Contest

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract This paper evaluates the Arkansas “Most Crop per Drop” Irrigation Yield Contest, a novel competition‐based Extension program designed to increase the adoption of Irrigation Water Management (IWM) practices among farmers. We use survey data to classify producers into three categories: contestants, informed non‐participants with some connection ...

Unraveling the Evolution of Silicic Volcanism in a Distributed Volcanic Field: Insights From Harrat Khaybar, Western Saudi Arabia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.

Investigating monitoring options for harbour seals in Special Areas of Conservation in Scotland [PDF]

, 2007
Managing a wild population effectively requires knowledge of the abundance and behaviour of the species. Harbour seals (Phoca vitulina) are usually counted when they come ashore at haul-out sites, and so it is important to understand how the number of ...
