Brown bear in the context of "Dzhendema"

The Marsican brown bear (Ursus arctos arctos, formerly Ursus arctos marsicanus), also known as the Apennine brown bear, is a critically endangered population of the Eurasian brown bear, with a range restricted to the Parco Nazionale d'Abruzzo, Lazio e Molise, and the surrounding region in Italy. The Marsican brown bear differs slightly from other brown bears in its appearance and hibernation techniques. The bear's popular name is derived from Marsica, a historic area of the modern-day region of Abruzzo where the bear has long had a significant presence.

With their existence dwindling, the Italian government has recently begun to stress their conservation. The park has become a sanctuary dedicated to animals such as the Marsican brown bear, with hopes of rekindling the large, yet isolative bears' once-thriving existence. Debate exists as to whether it should be considered a subspecies or a taxon of its own.

Shebenik National Park (Albanian: Parku Kombëtar i Shebenikut) is a national park in eastern Albania adjacent to the border with North Macedonia. It encompasses 34,507.9 hectares (345.079 km) and is specifically marked by a mountainous landscape supplied with glacial lakes, valleys, dense coniferous and deciduous forests and alpine meadows and pastures. Elevations in the park vary from 300 metres to over 2,200 metres above the Adriatic at the peak of Shebenik and Jabllanica, hence the name. It dwells a number of endangered species that are fast becoming rare in Southern Europe, including the brown bear, gray wolf and Balkan lynx. The abundance in wildlife can in part be explained by the variety of vegetation types and remote location.

The park offers some of the most rugged scenery in the eastern section of country that were carved into their present shapes by the glaciers of the last ice age. It is home to 14 glacial lakes, the highest situated between 1,500 and 1,900 metres elevation above the Adriatic. Small cirque glaciers are fairly common in the mountain ranges, situated in depressions on the side of many mountains. Two rivers flow and multiple smaller water sources flow through the park's area including the rivers of Qarrishte and Bushtrice, both of which are 22 km long. The park area is thought to contain one of the primary remaining ranges of the Balkan lynx, a subspecies of the Eurasian lynx.

The Vikos–Aoös National Park (Greek: Εθνικός Δρυμός Βίκου–Αώου Ethnikós Drymós Víkou–Aóou) is a national park in the region of Epirus in northwestern Greece. The park, founded in 1973, is one of ten national parks in mainland Greece and is located 30 kilometres (19 mi) north of the city of Ioannina in the northern part of the Pindus mountain range. It is named after the two major gorges of the area and encompasses 12,600 hectares (31,135 acres) of mountainous terrain, with numerous rivers, lakes, caves, deep canyons, dense coniferous and deciduous forest. The park is part of the Natura 2000 ecological network and one of UNESCO Geoparks and spans an elevation range from 550 to 2,497 meters (1,804 to 8,192 ft). Over 100,000 people visit the park each year and take part in activities including rafting, canoe-kayaking, hiking and mountain biking.

The core of the park, an area of 3,400 hectares (8,402 acres), comprises the spectacular Vikos Gorge, carved by the Voidomatis river. The gorge's main part is 12 km (7 mi) long, which attains a depth of 1,000 meters (3,300 ft), and has a width ranging from 2500 m to only a few meters at its narrowest part. The Aoös gorge, Mt Tymphe (2,497 meters (8,192 ft) at Gamila peak), and a number of traditionally preserved settlements form the park's peripheral zone. The park's remoteness and relatively small human population, combined with the great variation of biotopes and microclimatic conditions favors the existence of a rich variety of flora (1,800 species) in the area. Vikos–Aoös National Park supports a wide diversity of fauna, with a plethora of large mammals such as the brown bear, for which the park is one of the last European strongholds, and a variety of natural habitats and ecosystems that rank it among the most valuable parks for nature conservation in Greece.

Wakhan National Park is a national park in northeastern Afghanistan. Established in 2014, the park encompasses the entire Wakhan District of Badakhshan Province, extending along the Wakhan Corridor between the Pamir Mountains and the Hindu Kush, bordering the Gorno-Badakhshan autonomous region of Tajikistan to the north, Khyber Pakhtunkhwa and Gilgit-Baltistan in Pakistan to the south, and the Xinjiang autonomous region of China to the east.

Flora and fauna in the Wakhan National Park include some 600 plant species, the snow leopard, lynx, wolf, brown bear, stone marten, red fox, Pallas's cat, ibex, Marco Polo sheep, and urial. Remote and largely above the tree line, poaching and overgrazing, rather than mining and logging, currently pose the main threats. Around 15,000 Afghans of ethnic Wakhi and Kyrgyz background reside in the area. Foreigners must have an Afghan visa to tour the area.

The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore by body mass, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females are much smaller. The polar bear is white- or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water.

Polar bears are both terrestrial and pagophilic (ice-living) and are considered marine mammals because of their dependence on marine ecosystems. They prefer the annual sea ice but live on land when the ice melts in the summer. They are mostly carnivorous and specialized for preying on seals, particularly ringed seals. Such prey is typically taken by ambush; the bear may stalk its prey on the ice or in the water, but also will stay at a breathing hole or ice edge to wait for prey to swim by. The bear primarily feeds on the seal's energy-rich blubber. Other prey include walruses, beluga whales and some terrestrial animals. Polar bears are usually solitary but can be found in groups when on land. During the breeding season, male bears guard females and defend them from rivals. Mothers give birth to cubs in maternity dens during the winter. Young stay with their mother for up to two and a half years.

The grizzly bear (Ursus arctos horribilis), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America.

In addition to the mainland grizzly (Ursus arctos horribilis), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (U. a. middendorffi), the Kamchatka bear (U. a. beringianus), and the peninsular grizzly (U. a. gyas)—as well as the extinct California grizzly (U. a. californicus†) and Mexican grizzly (formerly U. a. nelsoni†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller.

Breeding pair is a pair of animals which cooperate over time to produce offspring with some form of a bond between the individuals. For example, many birds mate for a breeding season or sometimes for life. They may share some or all of the tasks involved: for example, a breeding pair of birds may split building a nest, incubating the eggs and feeding and protecting the young. The term is not generally used when a male has a harem of females, such as with mountain gorillas.

True breeding pairs are usually found only in vertebrates, but there are notable exceptions, such as the Lord Howe Island stick insect. True breeding pairs are rare in amphibians or reptiles, although the Australian Shingleback is one exception with long-term pair-bonds. Some fish form short term pairs and the French angelfish is thought to pair-bond over a long term. True breeding pairs are quite common in birds. Breeding pair arrangements are rare in mammals, where the prevailing patterns are either that the male and female only meet for copulation (e.g. brown bear) or that dominant males have a harem of females (e.g. walrus).

The Himalayan brown bear (Ursus arctos isabellinus), also known as the Himalayan red bear or isabelline bear, is a subspecies of the brown bear occurring in the western Himalayas. It is the largest mammal in the region, males reaching up to 2.2 m (7 ft 3 in) long, while females are a little smaller. It is omnivorous and hibernates in dens during the winter.

The cave bear (Ursus spelaeus) is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum.

Both the word cave and the scientific name spelaeus are used because fossils of this species were mostly found in caves. This reflects the views of experts that cave bears spent more time in caves than the brown bear, frequently using them to hibernate during the winter months. Unlike brown bears, cave bears are thought to have been almost entirely or exclusively herbivorous.
