World's northernmost coral reef in Japan bleached

Bleaching has damaged the world's northernmost coral reef in Japan, a researcher said Tuesday, the latest example of a global phenomenon scientists have attributed to high ocean temperatures.

Role of sponges in cold-water coral reefs investigated

Researchers from the University of Aberdeen have discovered that Spongosorites coralliophaga, which is a large sponge (a creature which attaches itself to something solid in a place where it can, hopefully, receive enough ...

Why a half-degree temperature rise is a big deal

The Paris Agreement, which delegates from 196 countries hammered out in December 2015, calls for holding the ongoing rise in global average temperature to "well below 2 °C above pre-industrial levels," while "pursuing efforts ...

Research explains Acropora corals' success—and their defeat

A new study paints a gloomy picture of the future of tropical coral reefs. According to a team of researchers including palaeobiologist Prof. Dr. Wolfgang Kießling from Friedrich-Alexander-Universität Erlangen-Nürnberg, ...

Scientists go high-tech to study fragile cold-water reefs

Coral reefs are generally associated with warm, shallow and crystal-clear waters in the tropics. Other species of coral, however, flourish in the deep cold ocean where they also form large reefs. Now researchers from the ...

New study of largely unstudied mesophotic coral reef geology

A new study on biological erosion of mesophotic tropical coral reefs, which are low energy reef environments between 30-150 meters deep, provides new insights into processes that affect the overall structure of these important ...

Climate change could stop fish finding their friends

Like humans, fish prefer to group with individuals with whom they are familiar, rather than strangers. This gives numerous benefits including higher growth and survival rates, greater defence against predators and faster ...
