Typically when hunting (especially with young prey), the bear pins its prey to the ground and then immediately tears and eats it alive. [214] Carrying pepper spray is highly recommended by many authorities when traveling in bear country; however, carrying two means of deterrent, one of which is a large caliber gun, is also advised. These bears are mainly nocturnal, except when with their cubs or mating, where they seem to be very independent and self-contained. Despite their reputation, most brown bears are not highly carnivorous, as they derive up to 90% of their dietary food energy from vegetable matter. [61], Brown bears usually occur over vast home ranges; however, they are not highly territorial. For the remaining 25%, it eats invertebrates that it finds in tree trunks or under boulders where more moisture accumulates and creates the perfect habitat for insects. The grizzly bear is officially described as "Threatened" in the U.S.. [10] which has had a major impact in conserving the bears. Studies have indicated that the most prevalent source of mortality for first-year cubs is malnutrition. [196][197], Brown bears seldom attack humans on sight and usually avoid people. Up until 2014, Italy and the European Union teamed up to conserve the bears in the Apennine Mountains. They are smaller and less fat because they have adapted to the climate of central Italy, which is milder than in northern Italy. The Marsican brown bear (Ursus arctos arctos, [2] formerly Ursus arctos marsicanus), also known as the "Apennine brown bear", and orso bruno marsicano in Italian, is a critically endangered [1] 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 first three molars of the lower jaw are very weak, and are often lost at an early age. The Alaskan population is estimated at a healthy 32,000 individuals. Despite their boldness and potential for predation if the bear is hungry, polar bears rarely attack humans, because they are infrequently encountered in the Arctic sea. The history of the bears of the Alexander Archipelago is unusual in that these island populations carry polar bear DNA, presumably originating from a population of polar bears that was left behind at the end of the Pleistocene, but have since been connected with adjacent mainland populations through movement of males, to the point where their nuclear genomes are now more than 90% of brown bear ancestry. Cerasuolo is an Italian village, the most populated hamlet (frazione) of Filignano, a municipality in the province of Isernia, Molise. The Marsican brown bear, otherwise known as the Apennine brown bear, has a relatively calm temperament, with no aggression shown towards humans. They will also wade into shallow waters, hoping to pin a slippery salmon with their claws. [217], Campers are often told to wear bright-colored red ribbons and bells and carry whistles to ward off bears. Roots and bulbs become critical in autumn for some inland bear populations if fruit crops are poor. [63][205] Most attacks occur in the months of July, August and September, the time when the number of outdoor recreationalists, such as hikers or hunters, is higher. Violent encounters with brown bears usually last only a few minutes, though they can be prolonged if the victims fight back. In terms of size, this particular species is relatively large in size in comparison to other bears. [157][158] Smaller carnivorous animals, including coyotes, wolverines, lynxes, and any other sympatric carnivores or raptorial birds, are dominated by grizzly bears and generally avoid direct interactions with them, unless attempting to steal scraps of food. Due to their claw structure, in addition to their excessive weight, adult brown bears cannot typically climb trees as well as both species of black bear, although in rare cases adult female brown bears have been seen in trees.

They may reach 5 to 6 centimetres (2.0 to 2.4 in) and may measure 7 to 10 centimetres (2.8 to 3.9 in) along the curve. The population range of the Marsican brown bear has been significantly reduced over the past hundreds of years. The polar bear is a recent offshoot of the brown bear.
