Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska

Fisheries Oceanography, Volume 35, Issue 3, Page 413-429, May 2026.
ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

Habitat‐Mediated Filtering, Rather Than Soil Properties, Shapes Plant Community Diversity on Nelson Island, Maritime Antarctica

Journal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
We test whether habitat (rocky outcrops and soil substrate) and soil‐mediated filters (fertility and texture) predict species richness and variability in cryptogamic community composition in Maritime Antarctica. Our results indicate that fine‐scale habitat constitutes the dominant environmental filter, promoting high species turnover.

Individual variability shapes interaction rewiring and fosters ecosystem restoration by reintroduced giant tortoises in the Seychelles

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Giant tortoises are critical for restoring lost ecological interactions on islands. Following their extinction in Seychelles centuries ago, key ecosystem processes like seed dispersal, browsing, and nutrient cycling were disrupted.

Nitrogen Stable Isotopes Track Ammonia Emission Sources and Ammonium Aerosol Formation Processes in the Marine Boundary Layer

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We measured the nitrogen isotopic composition of surface seawater and aerosol ammonium in the Weddell Sea region of the Southern Ocean to investigate the natural atmospheric cycle of marine ammonia emissions and aerosol ammonium formation in a region not overwhelmed by anthropogenic emissions.

Bacteria as Passive Passengers in the Equatorial Pacific Biological Carbon Pump

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bacteria are important agents modulating the efficiency of the ocean's biological carbon pump (BCP). The long‐standing view considers bacteria as degraders of sinking particulate organic carbon (POC), yet underappreciates their contribution to carbon export.
