![]() ![]() Interestingly, the salmon also avoided the bear model with a black body and no legs two to three times more often than the model with no body and black feet. He adds that a similar reasoning could also explain why fish-eating birds, such as gulls and terns, have evolved white underbellies. Reimchen says that, over millennia, salmon would have evolved an aversion to these black spots. “But a black bear against a white sky is going to look like little black spots.” “A white bear against a sky will be a bunch of white fragments against a white sky-so that’s still going to be camouflaged,” explains Reimchen. ![]() Overall, the experiment confirmed Reimchen’s hypothesis: salmon avoided the models with black bodies twice as often as the models with white bodies. Covering the “bear” with white or black fur, and sometimes adding fur-covered PVC legs, he put each version in a stream for 12 minutes to see if the salmon avoided it. To test the idea that the distortion would make spirit bears harder to see than black bears, Reimchen constructed a bear look-alike out of a plastic barrel. To actually prove this idea, though, Reimchen had to get creative-he had to consider what a hungry bear would look like to a fish. The white bears would have an easier time hunting, giving them a better chance at surviving and better odds of passing on their unique genes. While swimming upstream, he thought, the fish seemed better at avoiding the black bears. Thomas Reimchen, an ecologist at the University of Victoria in British Columbia who has been studying predator-prey interactions for more than 50 years, hypothesized that salmon can see black bears more easily than white bears. A new study has teased apart what that advantage could be. It implies that the white bears may have some sort of evolutionary advantage over the black bears. She has said that Song is like an oxygen for me and is always facing her own. Studies have shown that, in certain parts of British Columbia, from 10 to 30 percent of bears have this distinctive coloration-a rate that is far more frequent than what would be expected if the bears’ white fur was the result of random chance alone. XAI is a Japanese singer who won first place in the 8th Toho Cinderella Audition that was held in November 2016. ![]() ![]() a business might set out to develop an XAI model and use the following. That ratio-about one out of 10-has fascinated scientists. Explainable AI (XAI) will play a critical role in future analytics initiatives. According to one story from the Kitasoo/Xai’xais, the creator Raven made one out of every 10 bears white to remind people that the land had previously been covered by a glacier, and to appreciate the bounty the landscape offers today. Fewer than 200 of these unusual bears are estimated to live on British Columbia’s north and central coasts, where they have long held a special significance in coastal Indigenous cultures. Spirit bears are black bears with a recessive genetic mutation that turns their regular charcoal-colored fur a ghostly white. It turns out, it is-and there’s an intriguing reason why. But as time goes on, with the two bears snagging fish after fish, the white bear seems to be having an easier time. The white bear dips its snout and comes up with a wriggling salmon clutched between its jaws. In the Great Bear Rainforest, in coastal British Columbia, two large bears-one black, one white-wade into a stream.
