It ’s a time - honored tradition going back hundred : When sunlight returns to the Arctic each natural spring , the men of East Greenland jerk up their detent sleds and head out onto the frozen sea to hunt arctic bears .
But over the past few decennium everything ’s interchange . The weather in East Greenland is warmer and less predictable , the ocean meth more treacherous . The bears seem to be changing their behavior , too . And the Inuit people whose food security measures and finish is deeply intertwined with these gallant predator are being force to adapt .
These are the conclusions of a newresearch paperpublished in Frontiers in Marine Science , which interview 25 Inuit glacial bear hunters living in East Greenland about how the bear , the hunt club , and the climate of their Arctic country of origin are change . It ’s part of agrowing body of researchthat pull on traditional knowledge to understand unfathomed change happening in the Arctic .
There are 19 subpopulation of gelid bears scattered across the magnetic north . While some are in decline as sea ice red affects their migration path and piddle itharder for them to catch a meal , the bears ranging across the vast and distant coastline of East Greenland are for the most part a mystery story .
“ We do n’t know how many there are , ” Kristin Laidre , an Arctic life scientist at the University of Washington and lead author on the Modern study , told Earther .
That want of basic knowledge not only limits what we can say about the bears and clime change , but also the scientific advice to help meliorate food security measures in the neighborhood .
The novel sketch attend to fill that gap by turn over to aboriginal communities that rely on fauna , and are often more in melody with their well - being than anyone else . researcher interviewed hunters from two East Greenland settlements — Ittoqqortoormiit and Tasiilaq — on everything from weather and mood to hunt strategies to polar bear behavior , and how all of the above have changed over the last 15 years . The responses corroborate that the the great unwashed of East Greenland are dwell the impact of mood alteration today .
A with child majority of hunters described a spectacular loss of sea ice , an gain in quick , stormy weather , and quickly vanish glacier . Many noted how the cutting and weakening of sea icing has impacted the polar bear hunt , which traditionally involved travelling by mush .
“ Many Hunter say they can no longer do that because the routes they take are grave , ” Laidre said . “ So the hunt has switched to being boat based . That ’s a very profound alteration . ”
Orion from both community also notice more diametric bears hail near their towns than before , a change that may be due to a exit of ocean chicken feed , an increase in polar bear numbers , or some combination of those factors . In other areas , data point show that pivotal bears arespending more sentence on shoreas sea ice recedes .
Laidre said data from the subject area will be provided to management authority who set diametrical bear hunting quota , which were established across Greenland in 2006 without any stately scientific assessments of polar bear numbers in East Greenland .
Olivia Lee , a marine ecologist at the University of Alaska , was thrilled to see the subject integrate traditional noesis into gelid bear science . In Alaska , she noted , native hunting communities have played an important role inimproving quota for subsistence bowhead hulk harvest , all the whilemaking major contribution to science .
She sees this fusing of knowledge systems as part of a growing trend among younger academic research worker .
“ I consider the young generations are for certain a lot more concerned in how to combine these two knowledge system and how to use it for foresightful terminus sketch like climate change where we have n’t done a deal of watching , ” Lee told Earther .
This study has fostered biotic community tie that are helping advance other areas of polar bear enquiry , too . Since 2015 , Laidre has been engaged in a larger glacial bear universe assessment across East Greenland . So far , she says , hunters have proven very useful in helping scientist cipher out where they should be look for bears .
“ There ’s a lot we can ascertain from the great unwashed that exist in the Arctic , ” she said . “ And I think there ’s a lot science can gain . ”
