# Estimating A Deer Population Essay

Amazing Essays
Pre-Lab Questions
1. A population is a group of the same species that live in the same area and sometimes compete or can mutually benefit one another. A group of organisms will only be considered a population if they live in the same area in space and time. N is the true population size for a given group of organisms. This number is unlikely to be completely known. Whereas N hat is an estimate of population size.
2. There are two methods of sampling, direct and indirect. Direct sampling is an actual count of a population in a given area and is generally not easily feasible. Whereas indirect sampling is an estimate with subsamples of a population in a given area. This requires some extrapolation in order to estimate the total population, generally
Estimating a deer population (N) is considerably different than estimating a deer mouse population (N). Considering the fact that the home range for a deer population is much larger, the deer are physically larger, and would be very difficult to avoid double counting. The more space needed to be covered in the study the likelihood of double counting would be very high. Utilizing methods where a large area of land can be covered in a short period of time would be beneficial for estimating the population number such as using a helicopter and counting all of the deer observable. Whereas a deer mouse is significantly smaller, has a smaller home range, and lives underground. This would make counting the deer mouse difficult because you cannot see them unless they appear above ground or get trapped in a small mammal trap.
4. Estimating for a deer population (N) is considerably different than estimating a big bluestem population. The methods for estimating a big bluestem would be extremely difficult because grasses are known for being colonial, meaning that the root system is interconnected to other big bluestems that originate from the same seed making it very difficult to distinguish and count an individual. The methods for estimating a deer population are described

Bow hunters want to be able to hunt longer and hunt the rut without rifle hunters being able to hunt. The rifle hunters want to be able to hunt longer and hunt some of the rut. Bow hunters “prefer the whitetail rut free of firearm” because it's nearly impossible to kill a deer with a bow after gun season had started. Rifle hunters get to hunt the rut but they don’t have a long time to hunt, so that is why they have a problem with how long rifle season…

The article by Knight has an experimental design and does include a sample size that gathers the dispositions of the volunteers. Yet the sampling procedure Knight used was inadequate because it lacked random sampling and a larger sample size. Even though Knight’s sampling procedure and sample size may include voluntary response bias and atypical reports, it at least includes this sample and is not generalized to one individual of high status such as in Johnson’s article. Johnson (2004) could have easily included a sample size from another source to support his findings such as when he said that the woman who accused Kobe Bryant of race may be accused of deceitfulness. How many…

If predators are a problem in an area, lack habitat will be a deciding factor for survival. A lack of habitat will strand both fawns and fully grown deer to the open, where they are more likely to be taken by hunters and predators alike. Deer are most susceptible to predators in the fawning stage. In a study done during the non-fawning period, whitetail deer is found in only nine percent of coyote feces (Turner 5). The rest of the food consumed by the coyotes during this time was vegetation and smaller animals, such as voles.…

However, even though this zone has very few species the number of individuals in each species that make this biome a home for part of the year is very large. Take the massive herds of caribou or flocks of migratory birds as an example. The Arctic tundra is changing dramatically due to global warming. Already, more southern animals like the red fox have moved onto the tundra. The red fox is now competing with the Arctic fox for food and territory, and the long-term impact on the sensitive Arctic fox is unknown.…

Poachers are big problem in our world today, there the reason many animals are going into endangerment, not hunters. Poachers set a bad image for hunters who respect wildlife and nature.

Throughout the history of deer hunting in the United States, management tactics have rarely been taken advantage of. However, in recent years outdoorsmen across the nation have been driven by their passion of wildlife to begin implementing new, more sustainable practices. Wildlife management in the hunting industry stems from multiple sources, whether it be the pursuit of larger antlers or simply the need to put meat in the freezer. Nevertheless, the foundation of any program remains to be the same, a shared love of animals. The mistake numerous people make when starting a new program is not conducting the proper research ahead of time, which in a majority of cases, compromises success.…

According to Price, animals undergo reduced sensitivity due to changes in their environment (n.d., p. 245). Increased frustration is another major side effect (Ekstrand and Keeling cited in Barnett, December 2007, p. 214). “Many animals may never fully recover and die either in transit, shortly after, or even years later due to serious but hidden internal stress related problems” (Turner, 2008). Wild animals need to be surrounded by their own kind, and not humans. They have many psychological and behavioural needs which can only be met by living among their own.…
