Non-lethal tools for accurate sex identification in European #eel are required.
Our new #OpenAccess paper shows ultrasonography is an accurate, non-lethal tool for identifying sex, but molecular markers were less reliable.

Environmental pollutants can alter animal behaviour, but behaviour is rarely used in risk assessments. We outline how behaviour is key for population outcomes, and why it should be taken seriously in chemical regulation.

River heat waves are rising faster than the pace of air heat waves. That’s a problem for fish, drinking water quality, and food and energy production.
