Scientists say reindeer may be shrinking due to warming
December 14, 2016
Reindeer living on the Arctic island of Svalbard are getting smaller. Researchers say climate change may be the cause.
Scientists from Britain and Norway have studied the animals. They have found that adult Svalbard reindeer born in 2010 weigh 12 percent less on average than those born in 1994.
Ecologist Steve Albon is from Scotland's James Hutton Institute. He says rising temperatures in the Arctic mean Svalbard is getting more rain. The rain creates a hard ice sheet. The island's reindeer can't easily break through it. So it is more difficult for them to reach food.
Reindeer populations are also increasing. This is due to warmer summers. More reindeer means more competition among them.
Albon says researchers think there is a correlation between rising temperatures and reindeer weight. He says more research is needed to confirm the link.
Their findings were presented Dec. 12. They were announced at a meeting of the British Ecological Society.
