Which animals can best withstand climate change?

Credit: Pixabay/CC0 Public Domain Extreme weather such as prolonged drought and heavy rainfall is becoming more and more common as the global average temperature rises—and it will only get worse in the coming decades. How will the planet’s ecosystems respond? “That is the big question and the background for our study,” said biologist John Jackson, … Read more

‘Monkey media player’ suggests zoo animals may prefer to listen

Credit: University of Glasgow A “monkey media player” that lets zoo animals choose between video and sound files suggests they may prefer to spend more of their listening time than watching. The player is the latest development in ongoing zoo enrichment research from animal-computer interaction specialists at the University of Glasgow in the UK and … Read more

The ‘fuel of evolution’ is more abundant than previously thought in wild animals

Spotted hyenas adapt well to changes in their environment. Here, a clan of hyenas in the Ngorongoro Crater (Tanzania) quickly declared a broken-down roller as their new favorite resting place.
