New research reveals a fishing threshold for reef resilience

Coral reefs are the most biodiverse systems in the sea and central to the life of many coastal human communities. Half a billion people rely on coral reefs for protection from storms, provision of seafood as well as promotion ...

Coral-reef fish can become more risk-averse at their poleward range limits

University of Adelaide research shows the effect of warming is becoming increasingly obvious as water heats up off the coasts of Australia—and is especially noticeable in the way tropical fish are behaving as they migrate ...
