The Blob, a long-lasting mass of warm water, sat off the Pacific coast of North America for years, bringing new species to formerly cold waters. What allows some to survive while others fade away?
Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
The push for a new environmental crime has attracted high-profile backers including French President Emmanuel Macron, Pope Francis and Greta Thunberg. But we must get the details right.
Studies show some animals can recognise the threat of fire, and behave in a way that increase their chance of survival. But what about wildlife who have evolved in areas where fire was once rare?
Given the scale of the problem, five years was never enough time to turn things around. Clearly, we must reflect honestly on our successes and failures so far.
Baobab flowers have male and female parts but individual trees appear to be favouring one rather than the other. To keep tree populations healthy and fruitful, both types are needed.
For an ecologist working in a tangle of creeks in North Queensland, crocodiles are a tangible threat. We are food to them, yet we must learn to co-exist with these creatures.
