Island that looks like a bear from top năm 2024

Bear Island is considered Svalbard’s southernmost island, roughly half way between Spitsbergen and Norway’s North Cape. Although the last polar bears were seen in 2004, the name goes back to Dutch explorer Willem Barentsz and his visit in 1596.

The island has been used to hunt walrus, for whaling, and even coal mining has taken place. The strategic location on the border of the Norwegian Sea and the Barents Sea has led to a meteorological station being set up by Norway near Gravodden on Bear Island’s north coast. Some two thirds of the island is a relatively flat plain with shallow freshwater lakes and Ramsar Wetland, while the entire island and the surrounding waters are a Nature Reserve.

Bear Island has also been designated an Import Bird Area as it is a staging area for Pink-footed and Barnacle Geese and the steep cliffs south of Sørhamna are home to thousands of breeding seabirds,the area of most interest for a ship cruise, and even a Zodiac cruise on the few occasions the seas is calm.

Interesting facts about Bjørnøya (Bear Island)

This is a specially protected area where Zodiacs are allowed to cruise along the cliffs around Kapp Kolthoff. In smaller amounts Atlantic Puffins, Northern Gannets, Glaucous Gulls and Great Skuas are found in between the large Black-legged Kittiwake, Little Auk, Common Guillemot and Brünnich’s Guillemot colonies. The constant battering of the sea has not only created impressive sea caves and tunnels, but unfortunately the Russian vessel Petrozavodsk shipwrecked near Revdalen at the base of the limestone cliffs and the waves are causing a continuous disintegration of the remains of the ship.

In "Bear Island," bear biologist LaVern Beier of the Alaska Department of Fish and Game and the National Geographic Crittercam team join forces to vicariously walk with grizzlies into the deepest corners of their habitats.

One of the last grizzly strongholds, the dense rain forests of Chichagof Island in southeast Alaska hide more of these bears per square mile than any other place on Earth. But logging, road construction and human development are changing the shape of the grizzlies' world. As the modern world closes in, the great bear's world is shrinking, and encounters between humans and bears are on the rise.

Since the grizzlies on Chichagof Island spend most of their time hidden in the thick of the rain forest, it has been difficult to observe them on their turf without risking life and limb -- until now.

Prior to Crittercam, bear biologists used a variety of tools such as bear snares, radio collars and GPS systems to track grizzlies in their natural habitat. Terrestrial Crittercam now allows scientists to observe up close what bears do in the woods by transmitting live images from the bear's point-of-view to a remote receiver. The technology has made it possible to gather critical data and unprecedented television footage of how the elusive brown bears feed, breed, hunt, and survive on Chichagof Island. And in a place with more bears than humans, there is a great deal to learn to ensure a peaceful coexistence.

"Bear Island" producers Greg Marshall and Birgit Buhleier for National Geographic Television allow the viewer to experience firsthand the lessons of the wild as the scientists learn more about the bears' natural responses to their environment while they go about their daily lives.

The ABC Islands bears (Ursus arctos sitkensis) is a subspecies of brown bear that resides in Southeast Alaska and is found on Admiralty Island, Baranof Island, and Chichagof Island of Alaska. These islands have the colloquial name of the ABC Islands (Alaska)

When a question is scrutinized too intently the obvious can become elusive. The particular attributes of the individual animals in an isolated population that successfully reproduce determines which attributes are available in subsequent generations.

Mere millenia aren't enough to expect mutations to give rise to a significant number of new attributes. That implies that the bears on your island will be gradually reducing the diversity of their genome. Individuals express a subset of their genes in response to their environment. Unused potential isn't lost instantly, or even rapidly, except when its presence reduces reproductive success. Expect the bears characteristics to remain within the available diversity they arrive with.

The answer to the question "do I get giant cave bears or pygmies after 1000 generations?" depends on what effect the size of an individual has on its reproductive success. Its more common for the pressures on an island to favor smaller individuals, but giants like the Irish Elk and the Kodiak Bear result from environmental pressure favoring larger individuals.

In the hypothetical case, the environment is a benign climate with a predictably limited diversity of food sources and habitats. A large highly adaptable omnivore like a bear is likely to be so successful competing for food and habitat that the ecosystem collapses and the bears die off in a relatively brief time scale. An island ecosystem is fragile.

The habitats and species these bears share the island with would be more likely to remain in balance if some sort of an unusual circumstance forced the bears to compete with each other for an exogynous food source rather than exclusively with the other inhabitants for indigenous resources. For example, Kodiak bears compete with each other for fishing spots for the salmon run that is a huge fraction of their annual caloric intake. Its safe to assume that anything indigenous that a bear that didn't fish successfully could eat instead is likely to be eaten.

The argument that a certain population size is needed to ensure adequate genetic diversity is unavailing. Its an anthropic argument, i.e. that some population must be adequate for a species to survive/fail because the species isn't/is extinct. It only works a-posteriori, i.e. after the fact. There were an enormous number of passenger pigeons just a few decades before the last one died in a cage in a zoo. Tens of millions of individuals. That there wasn't anything in their genetic pool that would let them survive the loss of the continuous swath of old growth forests was self-evident after it happened, not before. Environmental pressures determine which individuals survive to be able to reproduce, and mating preferences tend to favor healthy individuals. If being smaller makes an individual more likely to survive and be healthy, larger is less likely to be available in later generations and vice-versa. How many individuals are needed to ensure sufficient genetic diversity for a species to survive some hypothetical environmental upset in the future has no role in the process. The genetic availability of un-expressed traits has no role in the process.
