“Rivers are critical resources that affect everything from watersheds to agriculture to energy. But rivers, in turn, have been impacted by humans, often in the form of hydraulic infrastructure such as dams and wells.
A new [Cornell] project… will create a global record that shows how river systems around the world have changed under human influence over the last 75 years…”

Freshwater fish populations plunge 81% as river migrations collapse

A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human pressures are cutting off their routes. Hundreds of species now need coordinated international protection. Experts say restoring river connectivity is critical to preventing further collapse.

325 Long-neglected migratory freshwater fish species need protection now: Report

CAMPO GRANDE, Brazil — In the wide, sandy stretches of Brazil’s Araguaia River, the piraíba, South America’s largest catfish, is a cornerstone of local fisheries. Fishers often recognize individual fish by markings and scars, catching the same fish in the same places over time, leading many to believe the species did not move very far. […]

🌊 Habitat #debate: Most austrolimulid occurrences are near shallow marine areas (or at least areas with #marine influence) and together with their wide distribution, challenge the idea they lived in fully #freshwater environments.

World Water Day: Earth’s freshwater reveals new species & faces mounting threats

Water covers most of our planet, yet less than 3% of it is freshwater and most of it is contained in glaciers, making it not readily usable. Contamination and overuse threaten the valuable supplies of freshwater that humans and other animals, especially aquatic organisms, depend on to live. On World Water Day, a United Nations […]
