Coral reefs support a quarter of all marine life, feed hundreds of millions of people and contribute vastly to the global economy. But they are dying in mass bleaching events, as climate change warms our oceans and breaks down vital relationships between corals and energy-providing algae.

The Baltic Sea is home to some of the world’s largest dead zones, areas of oxygen-starved waters where most marine animals can’t survive. But while parts of this sea have long suffered from low oxygen levels, a new study by a team in Finland and Germany shows that oxygen loss in coastal areas over the past century is unprecedented in the last 1500 years. The research is published today in the European Geosciences Union journal Biogeosciences.

Tropical forests are important to all of us on the planet. As well as being home for rare and fascinating biodiversity (like the lemurs of Madagascar), tropical forests lock up enormous amounts of carbon helping to stabilise our climate.  However tropical forests are also home to many hundreds of thousands of people whose lives can be affected by international conservation policies.

In a perfect world, garden plants would feed themselves. As it is, we’ve got to help them along sometimes.

Electronic radio tags could be used to track invasive Asian hornets and stop them colonising the UK and killing honeybees, new research shows.

A study led by the University of Southampton has shown the greening up of vegetation prior to the rainy season in Africa is more widespread than previously understood.

Scientists of the Leibniz Institute for Zoo and Wildlife Research (Leibniz IZW) in Berlin analysed the spatial behaviour of cheetahs. They showed that male cheetahs operate two space use tactics which are associated with different life-history stages. This long-term study on movement data of over 160 free-ranging cheetahs in Namibia has now been published in the scientific journal ECOSPHERE.

It turns out that to tell the sex of a Galápagos penguin, all you need is a ruler.

In a paper published April 5 in the journal Endangered Species Research, scientists at the University of Washington announced that, for a Galápagos penguin, beak size is nearly a perfect indicator of whether a bird is male or female. Armed with this knowledge, researchers could determine the sex of a bird quickly and accurately in the wild without taking a blood sample — speeding up field studies of this unusual and endangered seabird.

Salmon returning to the rivers of Vancouver Island to spawn have always had a long and perilous migration route. But in the past 10 years their time away has become deadlier than ever, with populations dropping precipitously.
