Crustaceans rule!
Ever wondered what kinds of wildlife dominate the world’s seas and oceans? Now there’s an answer, at least in terms of the number of species in different categories. It’s not fish. It’s not mammals. It’s crustaceans!
A mammoth Census of Marine Life has revealed that nearly one-fifth, or 19 percent, of all the marine species known to humans are crustaceans — crabs, lobsters, crayfish, shrimp, krill, barnacles and others far too numerous to mention here. The census didn’t count the actual numbers of animals beneath the waves — that would have been impossible — but it did count up the number of species in 25 marine areas. The aim is to set down a biodiversity baseline for future use.
It took 360 scientists to figure this out. Their findings were posted on Monday in PLoS ONE, an open-source peer-reviewed online scientific journal. An even more fulsome list will be out in October.
For now, there’s plenty of data to chew on: of the 25 marine areas around the world that were examined, Australian and Japanese waters were the most biodiverse, with nearly 33,000 species in each of these locations. The oceans off China, the Mediterranean Sea and the Gulf of Mexico round out the top five most biodiverse marine regions.
Coral erodes off Taiwan as divers take it home
Taiwan tourists are destroying a piece of exactly what they travel to see on an outlying mid-Pacific islet known — at least at one time — for its abundant coral reefs.
A pair of Taiwan environmental groups that marshaled 56 people to check the coral supply near Orchid Island, which is southeast of Taiwan proper, for the first time since 2004 found that the sensitive but colourful marine species covered only 18 percent of the surrounding ocean floor, down from 65 percent, said the Taiwan Environmental Information Center .
Peru clashes raise green issues
Clashes in the Amazon between indigenous protestors and Peru’s army that killed some 60 people last week throw some old issues into sharp new relief: development versus the environment and local versus foreign control of natural resources.
Indigenous tribes, worried they will lose control over natural resources, have protested since April seeking to force Peru’s Congress to repeal new laws that encourage foreign mining and energy companies to invest billions of dollars in huge tracts of pristine rain forest.
