The Black Bear By Ursus Americanus - 2083 Words

The black bear, ursus americanus, roams in different places in America including Texas. Its North America the black bears habitat ranges from Mexico all the way to Canada. In the state of Texas, the black bear is under threatened status, it also has the same status under the United States (Texas Parks and Wildlife Department). According to the Texas Parks Wildlife Department (2016) in the state of Texas they are usually found in the Western area in the Trans Pecos ecoregion. The Texas Parks and Wildlife Department (2016) has reported that there have been recent sightings of the Louisiana Black Bear in the Eastern part of Texas, where they used to have a strong population. This comes as surprising since the Louisiana Black Bear has an endangered status in the United States, as well as in the state of Texas. Even though the black bear species population in Texas is not as strong as it used to be in the past, many efforts are being done to recolonize the black bear in the South Western region of Texas by, studying their habitat as well as their eating habits, checking the DNA of the bears already in the area to see their genetic structures, regulating protection policies for black bears, and educating the people on the species. There are two subspecies of black bears in the South Western area of the state of Texas, which are the Mexican Black Bear, ursus americanus eremicus, and the New Mexican Black Bear, ursus americanus amblyceps, both species have been seen in the areaShow MoreRelatedThe American Black Bear ( Ursus Americanus )1882 Words   |  8 Pagesconditions. The American black bear (Ursus americanus) is native to North America, more specifically Canada and northern and southeastern United States. Ursus americanus once ranged from Mexico and all throughout United States and into Canada, but as human population increased and climatic conditions have changed, Ursus americanus moved to locations with lower populations and cooler climates, which are northern North America as well as southeastern United States. Ursus americanus are found with the highestRead MoreThe Loss Of Habitat Degradation1867 Words   |  8 Pageswildlife population contributes to inbreeding and intensified demographic stochasticity, which then affects a population’s adaptation capability and can ultimately result in extinction; a definite threat to species of concern such as the Louisiana black bear (Frankham 2005; Luo et al. 2016).

These species include, in decreasing order of body mass, black bears (Ursus americana), gray wolves (Canis lupus), coyotes (Canis latrans), bobcats (Lynx rufus), red foxes (Vulpes vulpes), fishers (Martes pennanti), and American martens (Martes americana) (MDNR n.d.). Black bears are omnivorous and primarily feed on plant material with most vertebrate material consisting of carrion (Dewey and Kronk 2007).

Contemporary management programs often center on augmenting or maintaining high quality wildlife habitat, the definition of which has primarily depended on a basic understanding of the species’ general ecology.

Predators and Competition Other scavengers, such as vultures, and coyotes are the only real competition for G. californianus, however, due to their size, they are often able to intimidate other competitors off. The Black Bear (Ursus americanus) and the Golden Eagle (Aquila chrysaetos), who will prey upon their young and the common raven that will feed on their eggs, are the only real natural threats facing the California condor.

Another example of behavioural plasticity is the shift in diel activity from diurnal to nocturnal in many large urban animals. For example, American black bears, Ursus americanus, bobcats, Lynx rufus, coyotes, Canis latrans, and even wild boar, Sus scrofa, have been known to become nocturnal in urban environments which reduces their interaction with humans (Podgà ³rski et al. 2013; Sol et al. 2013; Lowry et al
