Mystery of the Disappearing Dogfish: Transboundary Analyses Reveal Steep Population Declines Across the Northeast Pacific With Little Evidence for Regional Redistribution

Fish and Fisheries, Volume 27, Issue 1, Page 1-12, January 2026.
ABSTRACT Quantifying broad‐scale population trends and distribution change is critical for effective management and conservation of marine species, particularly under climate change. However, fragmented regional survey data often hinder such efforts for transboundary populations. A prime example is Pacific Spiny Dogfish (Squalus suckleyi, Squalidae), a

Climate Change Impacts on Antarctic Fish Diversity: A Circumpolar Perspective From eDNA Metabarcoding Assessment

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim Recent climate‐driven changes in the Antarctic marine environment, marked by regional differences between West and East Antarctica, may alter ecosystem dynamics. As key components of the food web, fish might reflect these changes. This study examines fish biodiversity patterns across four typical Antarctic seas by integrating eDNA analysis
