Chan­ge of mari­ne eco­sys­tem poses poten­ti­al thre­at on Litt­le auks 

First results of a new rese­arch pro­ject “Arc­tic Tip­ping Points” (ATP) show that high-arc­tic zoo­plank­ton spe­ci­es such as Cala­nus gla­cia­lis have star­ted to chan­ge their dis­tri­bu­ti­on are­as, migra­ting towards col­der waters, most likely due to recent war­ming wit­hin their tra­di­tio­nal ran­ge. This may for examp­le end­an­ger food sup­ply for spe­ci­es such as the Litt­le auk, Spitsbergen’s most abundant bird. Chan­ges of the mari­ne food chain are in any case very likely to have dra­ma­tic con­se­quen­ces for the who­le regio­nal eco­sys­tem.
