Evidence for dispersal personality in the guppy across ecological conditions, with a minor effect of relative brain size

Oikos, Volume 2026, Issue 8, August 2026.
Individuals that disperse typically exhibit specific phenotypical traits that facilitate dispersal and settlement success, known as ‘dispersal syndromes'. Consequentially, characterizing dispersers is crucial to understand other processes such as metapopulation dynamics and biological invasions.

Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, Volume 2026, Issue 8, August 2026.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

High‐Resolution Particle Imaging Reveals the Importance of Phytodetrital Aggregate Flux and Mesopelagic Grazing for Carbon Storage in the Southern Ocean

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract The biological, chemical, and physical processes in the mesopelagic zone that impact carbon flux to the deep ocean are poorly understood, particularly in the Southern Ocean, despite their importance to deep ocean carbon storage. Using a CTD‐mounted underwater imaging system, the Underwater Vision Profiler 5, we observed distributions of large ...

Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract For the first time, the Autosub Long Range (ALR) completed a fully autonomous, long‐distance (2,000 km) scientific mission, delivering new insight into coastal carbonate dynamics and air‐sea CO2 ${\text{CO}}_{2}$ fluxes. Equipped with a suite of oceanographic sensors, including a Lab‐on‐Chip (LOC) pH sensor and a Sea‐Bird SeaFET pH sensor, the

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 ...

Observations of High‐Frequency Internal Waves Near Submesoscale Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Nonlinear high‐frequency internal waves (HIWs) can occur at oceanic frontal interfaces but are rarely observed directly. This study presents field observations of HIWs near submesoscale fronts (SFs) in the northern Gulf of Mexico. A marine X‐band radar detected a series of organized bands, with a spacing of 50 ∼ 300 m, near SFs.
