The study of a scientific paper titled “Body condition among Svalbard Polar bears Ursus maritimus during a period of rapid loss of sea ice,” published in Scientific Reports on January 29, 2026 explains Svalbard bears are resilient due to local factors: increased abundance of alternative prey like harbour seals, reindeer, and walrus, which may compensate for reduced ringed seal access during ice-free months.<\/p>\n\n\n\n

\u201c[S]ea ice loss did not lead to a reduction in BC [body condition] among adult BS [Barents Sea] bears. Rather, after around 2000\u2026both males and females of different reproductive categories increased in body condition for the following two decades.\u201d \u2014 Aars et al., 2026<\/a><\/strong><\/h4>\n\n\n\n

<\/p>\n\n\n\n

Thick sea ice is not a necessary condition for polar bear health and survival.<\/p>\n\n\n\n

As local residents regularly observe, today polar bears successfully hunt bearded seal \u201cwhen sea ice is absent.\u201d<\/p>\n\n\n\n

They also routinely feed on harbour seals, walrus, and reindeer throughout the summer.<\/p>\n\n\n\n

Consequently, despite the expectation that a reduction in sea ice would harm polar bear populations, not only has the body condition (BC) of Svalbard bears improved since 2000, \u201cthe population has been increasing\u201d for the last 50 years.<\/p>\n\n\n\n

Interestingly, Svalbard polar bears \u2013 especially males \u2013 in the colder northern regions with thicker sea ice are in worse body condition (shown in blue) than bears in the warmer southern regions (red).<\/p>\n\n\n
