Cost‐Effective Quantitative PCR Assays for the eDNA‐Based Detection of Three Sympatric Salmon Species

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
We developed species‐specific dye‐based qPCR assays for three sympatric Northeast Asian salmonids (Oncorhynchus keta, O. masou, O. gorbuscha). After validating primer specificity, we used field eDNA to map their spatiotemporal distributions, offering cost‐effective, reliable tools for salmon conservation management.

Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...

Proximate Climate Drivers of Beaver Pond Occupancy and Range Expansion in Arctic Alaska

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
To understand why beavers are colonizing the Arctic, we evaluated which climate drivers underpin beaver pond dynamics. Warm Junes, mild winters, green summers, and wet springs facilitate pond establishment. Rapid improvement in these conditions across recent decades provides mechanistic support that climate change is driving beaver colonization of the ...

Spatiotemporal Thermal Variation Modulates Phenotypic Plasticity in Freshwater Turtle Growth, Behavior, and Sex

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Using a dataset that spans more than 50 years, we found that northern map turtles (Graptemys geographica) – an ectothermic species with temperature‐dependent sex determination – exhibited faster somatic growth rates, altered thermoregulatory behaviors, and a female‐biased sex ratio in recent years which were characterized by warmer, longer growing ...
