Great scat! Bears—not birds—are the chief seed dispersers in Alaska

It's a story of bears, birds and berries.

In southeastern Alaska, brown and  are plentiful because of salmon. Their abundance also means they are the primary seed dispersers of berry-producing shrubs, according to an Oregon State University study.

Grizzly bears go vegetarian due to climate change, choosing berries over salmon

Grizzly bears have stopped eating salmon in favour of elderberries after being forced to make a choice due to climate change. Warming temperatures meant that the berries are ripening earlier than usual, at exactly the same time as the freshwater streams on Alaska’s Kodiak Island are overflowing with sockeye salmon.

The island's brown bears typically feed first on salmon in early summer, followed by elderberries later in the season, in late August and September.
