Norwegian researchers document cascading environmental impacts
By Summit Voice
FRISCO — Norwegian scientists say they’ve observed how climate-linked extreme weather events have affected not just single species, but an entire ecological community in the Arctic.
Rain-on-snow events caused synchronized population fluctuations among all vertebrate species in a relatively simple high arctic community, the scientists said after documenting how populations of three species crashed at the same time.
These findings, published in the Jan. 18 issue of Science, may be a bellwether of the radical changes in ecosystem stability that could result from anticipated future increases in extreme events. (more…)
