Some herds likely to lose most of their habitat as climate warms

FRISCO — Digging deep into the genetics of caribou populations, scientists said the animals could disappear from most of their range in southern and eastern Canada in the next 60 years, as climate change fragments habitat.
The study, published Dec. 15 in the journal Nature Climate Change, found that caribou populations in the most climatically stable areas had the greatest genetic diversity. Climate projections, combined with the new genetic data, suggest the animals won’t fare well in the coming in decades.
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.
