Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses?

Global Change Biology, Volume 31, Issue 5, May 2025.
Nearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

Residents and Transients—Fish Community Dynamics in a Highly Anthropised Tidal North Sea Estuary Across the Annual Cycle

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Tidal estuaries provide important spawning, nursery and feeding habitats for a wide diversity of species and serve as transit areas for diadromous fishes. However, they are globally among the most impacted aquatic ecosystems, pressured by anthropogenic alterations and global change.

First Records of the Endangered Pallid Sturgeon (Scaphirhynchus albus) in the Des Moines River, Iowa: A Significant Potential Range Expansion

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
The pallid sturgeon Scaphirhynchus albus, a large, long‐lived fish endemic to the Missouri and Mississippi River Basins, was listed as a federally endangered species in 1990 due to population declines driven by profound anthropogenic habitat alterations, including river fragmentation by dams and channelization. In contrast, its congener, the shovelnose
