Author:

The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study published on Monday.

Acidification, blamed on the transformation of rising levels of the greenhouse gas carbon dioxide from the air into carbonic acid in the sea, makes it harder for shellfish and crabs to grow their shells, and might also impair fish reproduction, it said. ...

As we’ve written before, the mysterious mass die-off of honey bees that pollinate $30 billion worth of crops in the US has so decimated America’s apis mellifera population that one bad winter could leave fields fallow. Now, a new study has pinpointed some of the probable causes of bee deaths and the rather scary results show that averting beemageddon will be much more difficult than previously thought. ...

Just 9% of the millions of tonnes of fish caught by China's giant fishing fleet in African and other international waters is officially reported to the UN, say researchers using a new way to estimate the size and value of catches.

Fisheries experts have long considered that the catches reported by China to the UN's Food and Agriculture Organisation (UNFAO) are low but the scale of the possible deception shocked the authors. ... Read more about Chinese fishing fleet in African waters reports 9% of catch to UN

A new method for monitoring the decline in bee populations may prove a useful tool in much-needed conservation efforts. It requires only a few hundred pan traps: bright shallow bowls partly filled with soapy water or propylene glycol.

When United Nations experts noticed that crop production was flagging in seven countries around the world, from Brazil to Nepal, they contacted Gretchen LeBuhn, an associate professor at San Francisco State University who studies bees. ... Read more about Counting the Vanishing Bees
