Common species mirror rare animals’ response to global change
The populations of common animals are just as likely to rise or fall in number in a time of accelerating global change as those of rare species, a study suggests.
More nutrient reduction still needed to save lakes in China
Chinese people have been paying more and more attention to water safety, especially since the Wuxi “water crisis” in Lake Taihu in 2007. However, more than 10 years after the crisis, how healthy are Chinese lakes now? A scientific research…
