Preconditioning of Polynya Formation by Ocean Mixing at Maud Rise, Antarctica

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic open‐ocean polynyas trigger vigorous wintertime convection, influencing ocean circulation and atmospheric processes. In the Weddell Sea, interaction between the Weddell Gyre and the Maud Rise seamount generates a Taylor column that favors polynya formation.

Subglacial Lake Discharge Affects the Age and Concentration Distribution of Dissolved Organic Carbon in Ross Sea Surface Waters

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract The Ross Sea continental shelf plays a key role in the global carbon cycle. However, the sources and cycling of dissolved organic carbon (DOC) in the region are poorly understood. Here, we determined the radiocarbon (14C) and stable carbon isotope (13C) contents of DOC in addition to those of dissolved inorganic carbon (DIC) in the Little ...

From Glacier to Coast: Seasonal Hydrographic Dynamics in the Ella Ø Fjord Complex, East Greenland

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Greenland's ice loss is increasing across the ice sheet due to enhanced surface melting and accelerated glacier discharge, contributing to sea level rise and potentially altering ocean circulation and marine ecosystems. Fjords play a key role in this process by linking the ocean and ice sheet, but currently a limitation is that most fjords in ...

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Convergent digestive adaptation to resource limitation in an insular lizard across a microgeographic archipelago

Journal of Animal Ecology, Volume 95, Issue 8, Page 1372-1385, August 2026.
Replicated mainland–islet populations of the Skyros wall lizard reveal consistent divergence in digestive physiology, including gut morphology, passage time, digestive efficiency and enzyme activity. These results show how ecological variation in resource availability can shape digestive performance across populations in insular environments.

Between‐species contagion drives HPAI transmission and mass mortality in seabirds

Journal of Animal Ecology, Volume 95, Issue 8, Page 1488-1503, August 2026.
Modelling the unprecedented avian panzootic caused by High‐Pathogenicity Avian Influenza (HPAI) across the Northeast Atlantic gannet breeding metapopulation, we estimated 28% (95% CI: 21%–34%) HPAI‐related mortality. Large‐scale outbreak initiation was best explained by external infection sources, most likely, other seabird species.

Demographic responses to population recovery illustrated by 30 years of monitoring a once critically endangered parrot

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings highlight the dynamic nature of demographic processes throughout population recovery and emphasise the value of continued monitoring beyond apparent recovery to detect density‐dependent shifts in demographic rates of wildlife populations.

Enriching historical biologging datasets on seabirds using deep neural networks: A transformer‐based approach to infer energy expenditure proxy from GPS and environmental data

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2408-2423, August 2026.
Abstract Recent advances in biologging have led to the widespread use of accelerometers, which generate high‐resolution movement data essential for understanding animal behaviour. Derived from tri‐axial accelerometry, Overall Dynamic Body Acceleration (ODBA) serves as a proxy for energy expenditure that is less invasive and more cost‐effective than ...

Geolocation with a magnetic sensor

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2395-2407, August 2026.
Abstract Many migratory animals use spatial variation in the Earth's magnetic field for orientation and navigation. This raises the possibility of exploiting these same cues to geolocate and track migratory animals throughout their annual journeys. Magnetic‐based geolocation could be particularly valuable for small aerial and aquatic species, for which
