Why are people so dang obsessed with Mars? In Europe, brown bears are also increasing their numbers and expanding their range, especially in Norway and Sweden, where the population has gone up from around 1, bears in to roughly 3, today. After having eliminated or severely reduced their brown bear populations, Italy, Austria, and France are now reintroducing them to parts of their former range.

There, the brown bear population appears to be stable. For brown bears living throughout the rest of Eurasia, the story is less optimistic.

Both brown bears and Asiatic black bears U. Back in North America, in addition to island-hopping along the west coast, brown bears are also heading north. The IUCN has had to redraw the brown bear range map to reflect this recent shift.

In the Arctic Archipelago, brown bears now roam a landscape significantly altered by climate change. They are taking over polar bear territory—and encroaching on their DNA. Banks Island is a vast, treeless expanse of tundra and snow in the western Arctic Archipelago. The Inuvialuit people have found instances on the island of polar bears and brown bears reproducing, resulting in hybrid bears that share characteristics of both species. These individuals are not sterile like mules—horse-donkey hybrids—they produce fertile offspring.

This reveals their close genetic heritage. In terms of evolutionary time, polar bears recently evolved from the brown bear line and moved into, learned to exploit, and became fully adapted to the Arctic environment in the past , years. But the Arctic is changing fast. The temperature is rising at three times the global rate, the sea ice is disappearing, and the tundra is turning to mud. Brown bears are expanding their range into polar bear habitat. The two species have begun to interbreed, creating hybrid offspring.

How did brown bears get to Banks Island? The shortest route is through neighboring Victoria Island, where the crossing from the North American mainland is The resident polar bears are phenomenal swimmers and are called sea bears U. One female polar bear was recorded as having swum kilometers over a period of nine days. Brown bears? Not so much. They are strong swimmers, but prefer to stay close to shore. The brown bears arriving on Banks Island must have arrived by walking across seasonal sea ice.

McLellan believes the mystery of why there is no viable grizzly population on Vancouver Island likely comes down to that gap of three to 4. When they get there, he says, they find suitable habitat, but no chance to mate. Around much of the world, when given the chance or forced by circumstance, brown bears are expanding their range.

Just as a changing Arctic results in brown bears moving north today, evidence from a previous era of climate disruption holds clues of them moving south to Vancouver Island. Some 60 kilometers west of Johnstone Strait is a rare karst landscape overlain with clearcut forest. For eons, water has dripped and coursed through the limestone mountains on northern Vancouver Island, creating a network of caves. Inside the rubble-choked entrance of one of those caves, discovered in , the remains of three bear species were found.

The cave would become known as Pellucidar, after the fictional subterranean world created by American writer Edgar Rice Burroughs of Tarzan fame. The bones found in the cave provide hard evidence that brown bears were present on Vancouver Island at the end of the last ice age. Radiocarbon dating and DNA analysis revealed that some of those bones came from two individual brown bears that lived some 12, years ago. Brown bears arrived in North America from Eurasia by crossing Beringia, the now-submerged land connecting modern-day Siberia and Alaska.

Evidence suggests that, as the ice sheets retreated, brown bears ventured farther south into the continent at around the same time people did. On the shore of Calvert Island, just 63 kilometers north of Vancouver Island, recently discovered human footprints were radiocarbon dated to 13, years ago. Along with these newly arrived people, brown bears entered a novel and changing environment. They also encountered two other bear species that had already been living in the area for millennia.
