Great Barrier Reef

Over the past 250 years, the ocean has become about 26% more acidic on average globally.

A study of an area of the Great Barrier Reef where the number of breeding great crested terns has grown ten-fold, probably due to extra food from trawl by-catch, suggested that lesser crested and sooty terns have moved away and now breed on a part of the reef where fishing is banned.

Egg laying begins in India and Polynesia in May, followed by colonies in the Philippines in July, north-east Australia in September, oceanic Indian colonies from September to November, and the Great Barrier Reef from November to December.
