The populations of common animals are just as likely to ri or fall in number in a time of accelerating global warming as tho of rare species， a study suggests.
Until recently， scientists were still accumulating data on how animal populations were shifting over time globally across the different regions of the planet.
Making u of the newly available data， a team of University of Edinburgh rearchers studied nearly 10，000 animal populations reco?rded in the Living Planet Databa between 1970 and 2014 to provide a new perspective on animal population change. The include records of mammals， reptiles， sharks， fish， birds and amphibians.

The team found that 15 percent of all populations declined during the period， while 18 percent incread and 67 percent showed no significant change. Amphibians were the only group in which population sizes declined， while birds， mammals and reptiles expe
rienced increas. “The overall decline in amphibians makes them a priority in conrvation efforts，”rearchers say， “as their loss could have knock?on effects in food chains and wider ecosystems.”
Gergana Daskalova， of the University of Edinburghs School of GeoSciences， who led the study， said， “We often assume that declines in animal numbers are prevalent everywhere. But we found that there are also many species which have incread over the last half of a century， such as tho which do well in human?
transformed landscapes or tho which are the focus of conrvation actions.”
Dr Isla Myers?Smith， also of the School of GeoSciences， who co?authored the study， said， “Only as we bring together data from around the world， can we begin to really understand how global change is influencing the biodiversity of our planet.”
