The Importance and Mechanics of Near‐Seafloor Oxygenation Events in Shallow Coastal Environments

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Bottom‐water oxygen (O2) possibly constitutes the strongest regulating factor on ecosystem function of the seafloor environment. The conventional view of bottom‐water O2 regulation in temperate regions is a strong seasonal variability imposed by deposition of fresh, labile organic carbon following the spring and fall plankton bloom generating ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1629-1641, September 2026.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Water Beings and Capitalist Relations in India's Sundarbans Delta

American Anthropologist, Volume 128, Issue 3, Page 595-606, September 2026.
ABSTRACT This article explores entanglements between water cosmologies and capitalist transformation in the Sundarbans delta of West Bengal, India. It traces how “awakened” tidal creeks have been iteratively enclosed as private fisheries from the colonial period to the present, with particular focus on the expansion of commercial aquaculture over the ...

Impacts of Ocean Acidification on Reproduction and Early Life Development in Marine Teleost Fish—A Synthesis

Fish and Fisheries, Volume 27, Issue 5, Page 1176-1192, September 2026.
ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

Enabling Quantitative eDNA Monitoring in Lotic Ecosystems by Incorporating Hydrological Characteristics and Allometric Scaling

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Effective freshwater biodiversity monitoring requires scalable methods to estimate fish abundance or biomass. Environmental DNA (eDNA)‐based approaches offer a promising alternative to observational methods. However, translating eDNA concentrations into reliable biomass estimates remains difficult in flowing waters because hydrological ...

Endemic but not eroded: Genomic distinctiveness and conservation genomics of the British swallowtail butterfly (Papilio machaon britannicus)

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1260-1274, September 2026.
Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, Volume 109, Issue 3, Page 1760-1770, September 2026.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Otolith‐based age determination in Anguilla anguilla (Linnaeus 1758) from Lake Vistonida, NE Greece: A modified Crack and Burn protocol

Journal of Fish Biology, Volume 109, Issue 3, Page 1942-1946, September 2026.
Abstract This study presents a modified otolith preparation protocol to estimate the age of Anguilla from Lake Vistonida (NE Greece). In experimental attempts, 300 otoliths were processed using standard and modified eel ageing methods, producing low success rates (0%–20%) due to poor annuli visibility and structural damage.
