BBC A healthy fish population could be the key to ensuring coral reefs survive the impacts of climate change, pollution, overfishing and other threats. Australian scientists found that some fish act as “lawnmowers”, keeping coral free of kelp and unwanted algae. : The assembled experts told parliamentarians that fish able to graze on invading plants [...]

Independent Britain is to build the world’s biggest butterfly house as a giant visitor attraction with a giant conservation message: stop butterflies disappearing.

NOAA The least biologically productive areas of the oceans are expanding much faster than predicted, according to a new study by researchers at NOAA and the University of Hawaii. This change in ocean biology, linked to the warming of sea surface waters, may negatively affect the populations of many fish species trying to survive in [...]

BBC Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice. Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years. : Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever [...]

Practical Fishkeeping Italian scientists have found that ingredients in sunscreen can hasten coral bleaching by promoting viral infections in the symbiotic algae (zooxanthellae) in the coral. The study, to be published in the journal Environmental Health Perspectives, was conducted by Roberto Danovaro, Lucia Bongiorni, Cinzia Corinaldesi, Donato Giovannelli, Elisabetta Damiani, Paola Astolfi, Lucedio Greci and [...]

For some, global warming is taking away [...]

AP Just a few years ago, the lush coral reefs off Bali island were dying out, bleached by rising temperatures, blasted by dynamite fishing and poisoned by cyanide. Now they are coming back, thanks to an unlikely remedy: electricity. The coral is thriving on dozens of metal structures submerged in the bay and fed by [...]

MSNBC John Bruno isn’t attending the U.N. climate talks being held in Bali, Indonesia, but he does have some advice for any delegates looking to take in the resort’s famed reefs: enjoy it now, because if sea temperatures continue to rise, expect to see more — and more severe — disease outbreaks that wipe out [...]
