Sweden has one of the fastest bear reproduction
rates in the world, and it seems that females were
spending more time with their cubs.
"We needed to
provide evidence,
and then that
triggered new
questions,"
says
Joanie Van de Walle,
A PhD student in the Department of Biology at the
Université de Sherbrooke in Quebec, Canada.
Van de Walle is part of an international team of
researchers who combed through decades of data
on brown bear populations in
Sweden to investigate
this trend. By following the lives of hundreds of
bears, the researchers determined that more
mothers are raising their cubs for one year
longer than they have in the past.

This behavioral shift can be directly attributed to
humans, according to a study published March 27
in Nature Communications. With a population
hunting tactics can keep bear numbers at bay.
This behavioral shift of mother bears caring for
their young for a longer time could be directly
related to hunting regulations.
