"When sea ice melts, polar bears must move onto land for several months without
access to food. This fasting period is challenging for all bears, but
particularly for polar bear mothers who are nursing cubs.

Our research, published in Marine Ecology Progress Series, found that polar
bear lactation is negatively affected by increased time spent on land when sea
ice melts.

Impaired lactation has likely played a role in the recent decline of several
polar bear populations. This research also indicates how polar bear families
might be impacted in the future by continued sea-ice loss caused by climate
