Sex- Based Migration in Black Bears (Ursus americanus) displayUrsus americanus, the American black bear is the most common of the creative activitys bear species, about up to twelve times more abundant than grizzly or brown bears. They usually occupy set atomic number 18as but their habitats are highly variable from the Louisiana Bayou to the Labrador Tundra, and the Northwestern come down forests in between. (Wilson & Ruff, 1999) American black bears are hunted legally seasonally due to their widespread population and distribution. However, with the increase in deforestation for industrial enterprise in the Tri-State (New Jersey, New York, Pennsylvania) area, the habitat loss could have adverse cause on the black bear populations. An interference with their natural territory could snuff it to alteration in the dispersal patterns. (Dixon, Wooten, McCown, Oli, Eason, & Cunningham, 2007)Black bears are omnivorous and although a part of their diet consists of meat and insects, they primarily rely on fruits and zesty for their diet. thitherfore, a plants annual cycle of fruiting is level(p) to a bears annual behavior and its physiological cycle. (Wilson & Ruff, 1999) Bears race to congregate and gather in an area with an abundance of food and now and then return time and again to areas with ease of access to foods- like dumpsters. (North American Bear Center) Despite this, black bear dispersal is not reliant on local food shortages in population densities that have been observed. (Rogers, 1987)There are other factors influencing the dispersal and migrations of black bears which have been studied. Urus americanus are not known to monogamous and mate promiscuously. (Rogers, 1987) Males mate with more than iodin female and disperse more, sometimes looking for oth... ... cubs will be evaluate to be found closer to or at their initial plaza range.If however, a larger number of female bears desoxyribonucleic acid is collected farther than their home ranges , it could imply that previous studies bases solely on observation or mark and recapture methods were inaccurate due to the extra populations that were sampled. An observation of this nature could imply that sows dispersed farther in explore for new mates or safer dens for their cubs rather than males who were expected to wander away. much likely though, this observation could be an exception to the rule or plainly flawed collection and processing techniques. Providing that the study conducted is not faulty, it will bring out important information regarding dispersal patters of the American black bear. Even the data gathered in the course of this study can be utilize for further research on Ursus americanus.
