A Method to Implement Natural Flow Regimes for Regulated Rivers

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Rivers throughout the world have been dammed for flood control, irrigation, hydropower, and water storage for centuries. Dams service the economic and development needs of societies, but degrade the ecology of rivers. To conserve diminishing aquatic species and their habitats, methods are needed to help managers implement flow releases with ...

Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

Integrative Zoology, Volume 21, Issue 3, Page 609-623, May 2026.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Resilience to Cardiac Aging in Greenland Shark Somniosus microcephalus

Aging Cell, Volume 25, Issue 5, May 2026.
Greenland shark Somniosus microcephalus shows severe cardiac aging such as fibrosis, lipofuscin buildup, mitochondrial damage, and oxidative stress, unseen in comparison species Etmopterus spinax and Nothobranchius furzeri, yet remain healthy. S. microcephalus resilience suggests unique mechanisms that preserve heart function for centuries, offering ...

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, Volume 68, Issue S2, Page S104-S129, May 2026.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Dams and Introduced Species Drive Patterns of Environmental Adaptation in an Iconic but Imperiled Coldwater Fish (Brook Trout, Salvelinus fontinalis)

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Freshwater biodiversity is being disproportionately negatively impacted by anthropogenic stressors including climate change, partly due to limited opportunities to seek more favorable conditions compared to marine and terrestrial species. Management plans that maintain locally adapted genotypes, and integrate active management interventions ...

A Review of a Decade of Anadromous Salmonid Hatchery (And Stocking) Research: Insights for Policy, Management and a Changing Climate

Fish and Fisheries, Volume 27, Issue 3, Page 431-450, May 2026.
ABSTRACT Hatcheries and stocking programmes have long been a cornerstone of fisheries management, seen as tools for fisheries enhancement and/or conservation of threatened populations. Their use draws controversy, however, from a growing body of research over the last 50 years suggesting that stocking can have negative consequences for wild stocks, and
