How it’s being used: The Barents Sea
near Svalbard, Norway, has long been
home to a large breeding population of
polar bears, but that region is warming
more quickly than other Arctic locations.
Lacy and his team assessed warming
trends, along with habitat and food loss,
and found that the greatest threat to
polar bears there is dwindling populations
of ringed seals, the bears’ primary food
source. They used Vortex to understand
each species and MetaModel Manager
to explain how the species interact and
how the interactions all depend on ice
conditions. Findings may help to predict
the Arctic regions where species will be
most resistant to the effects of a warming
climate. This information could direct
the location of wildlife refuges where the
fragile Arctic fauna can be protected.
