The personality changes that stroke can cause can be intense for everybody concerned. And there is no guarantee that they will go away. Of course, this situation is full of opportunities for guilt, despair, anger, shame and depression â and not just for the survivor. âI tell all the stroke families I work with, there is life after stroke, but you have to stay active and stay around people.
Their scientific name means maritime bear, and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.[7] Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species, and at least three of the nineteen polar bear subpopulations are currently in decline.[8]
Over the years, scientists have uncovered an evolutionary path suggesting that polar bears are a relatively new species, and actually a subspecies, of Ursus arctos, more widely known as the brown bear. Scientific evidence has found that the brown bear, a species that also includes grizzly bears, was a âprecursorâ to polar bears, which then went on to develop specializations for inhabiting the harsh Arctic. Proving their genetic compatibility, brown bears and polar bears can mate and produce viable, or fertile, offspring.
