Raccoon Survival Essay
Raccoon Survival Augmentation Due to Specific Characteristics of Urbanized Settings
Urbanization poses serious threat to natural ecosystems and biodiversity (McKinney 2002). Not all species fall prey to urban development; some, often called synanthropes, are able to adjust to human alterations (McKinney 2002, Gross et al., 2012). Understanding the impact of urbanization and the strategies used in response is valuable to many, such as wildlife conservationists. Raccoons are considered to be synanthropes (Gross et al. 2012), and have been found to occur in greater densities in urbanized sites in comparison to rural sites (Prange et al. 2003). This paper looks into how urban ecosystems promote raccoon survival, and thus abundance and distribution, through providing opportunities to outcompete similar species, decrease home range size, and increase survival rates. Live-trapping and road-kill surveys are common methods of data collection when researching raccoons. Prange and Gehrt (2004) used a combination of these methods and statistical modelling to analyze

    The two species of sloths include the Brown throated three toed sloth, or the Bradypus variegatus, and the Hoffman’s toe-toed sloth also known as the Choloepus hoffmanni. A few differences between the two toed sloth and the three toed sloth can be found in their digestive systems, home range, relationships with other organisms, diet, and their anatomical structure. According to the map provided, the two species of sloths were found to be dispersed quite randomly. However, the majority of two toed sloths were found in the agricultural land, and the majority of the three toed sloths were found in the lowland second-growth forest. By further observing the differences in diet, mobility, and relationships sloths have with…

    The Brunette Basin Watershed is a 73 square kilometre watershed that stretches into several municipalities in the Lower Mainland, including portions of Vancouver, Burnaby, New Westminster, Coquitlam and Port Moody (Greater Vancouver Regional District [GVRD], 2001a; see appendix A). This watershed is centralized within a highly developed urban area, meaning that humans and the natural environment interact on a regular basis. However, the impact of humans on this watershed has degraded animal habitats and the ability for animals to live within the watershed. This project will examine the habitats and the animals that exist within the Brunette Basin Watershed, the importance of these natural habitats for these animals, and the disappearance…

    Jaguarundi is an extremely rare animal in Northern Mexico, and it is one of the world’s endangered animals. Habitat destruction poses the most severe threat to its existence. Land and agricultural development lessens the Jaguarundi’s population in Arizona and Texas in the United States. We know very little about this small cat species’ behaviors and reproductive biology, as well as its number in natural habitats. However, one certain thing is that, if the jaguarundi is in a confined environment, its breeding rate…

    The Red Wolves of North Carolina are the last of their species. There are approximately forty Red Wolves left and they’re all live in the Albermarle Penninsula in North Carolina. Red wolves are on average, five feet long from nose to tail. They’re larger than the coyotes, only averaging three feet from nose to tail. The red wolves, coyotes, and eastern wolf are all from the original “Ancient Wolf”. Since the beginning of wolves, they have been cross breeding to create hybrids. Over time, the ancient wolf evolved into three separate species of wolves. The coyotes have taken over in population and management for controlling the offspring has been bad for years now. In 2012 is when management switched in the Fish and Wildlife organization and…

    Because it is certain that wildlife is declining and cats have a significant role as to why this is occurring. (8) Is what makes this argument to be invalid. The author states the decline to be 68% but in context he is blaming the cats. But has written “a variety of factors are to blame”, this doesn’t make sense because he is trying to blame cats for the decline in wildlife but it is really because of the clearing of land. (9) Is also dependent on this because it is farmland animals where the land is being heavily cleared for more urbanization. Yet he is still trying to blame cats for this with (11). The fact presented is not enough in detail to support the claim. It lacks detail as to how many rats and mice do they kill every year. What proportion are chipmunks, squirrels and rabbits killed. Cats are used to control population numbers for rabbits so this makes the fact unreliable. It also lacks the reproduction rates to which these animals replenish their population. Therefore in the context of the argument when trying to blame cats for the decline in wildlife it is invalid and thus a bad…

    Bear attacks are rare, however, in bear-country areas where humans and bears coexist such as British Columbia (BC), the encounters are nearly inevitable. This study looks at newspaper articles on grizzly and black bear attacks on humans in BC and analyses an spatial or temporal trends from 2000-2016. The data showed that grizzlies had a higher attack rate of 18 attacks/10,000 individuals than black bears with 1.9 attacks. 10,000 individuals. Females with cubs also showed to have the highest frequency in attacks within the last 16 years. The locations of these attacks were quite variable with minimal patterns, however, generally, grizzly bear attacks occurred in the backcountry while black bear attacks ensued more in the front country with greater…

    In the years since the wolf reintroduction, Yellowstone has become a premiere scientific laboratory for wilderness observation and ecosystem recovery. Scientists have come from around the world to watch the effect wild wolves have on the park. We have discovered that an ecological effect called the “trophic cascade” has taken over Yellowstone, with the wolves initiating a more natural ecosystem balance than has been seen in over sixty-five years.…

    Sanctifying The Wolf

    In Is Science in Danger of Sanctifying the Wolf?, L. David Mech writes that sweeping, definitive claims about wolf effects on ecosystems are premature whether made by the public or by scientists. Mech believes those definitive claims are premature because he considers the accuracy of studies regarding the impact of wolves is questionable, and the hypotheses not as rigorously tested as they need to be. The effects of wolves on an ecosystem fall into three categories: direct effect on coyotes, benefits to scavengers, and cascading effect of wolf interactions with prey to other species in the wolf food chain. The first, reduction of coyotes is unclear. Packs…
