Kodiak brown bears going for berries over salmon

1 post in this topic

Kodiak brown bears are abandoning salmon-their iconic prey-due to climate change, according to a new study.

The bears are more interested in chowing down on early-arriving red elderberries. The likely result of this "prey switch," the researchers conclude, is a disrupted ecosystem on Alaska's Kodiak Island.

 

birds that depend on bears pulling salmon out of the stream, could be seriously affected, Other far-reaching effects may include changes in bear demographics due to the change in their diet, evolving salmon populations and impacts on plant pollinators.

 

This overlap in their resources forces the bears to make a choice that could in the long run result in fewer bears and/or unexpected changes in ecosystem structure," Stanford said.

this has been observed since 2014, the berries appear earlier and attract the bears

 

we are messing with this with uncertain results
