The Pros And Cons Of Conservation Biology

Improved Essays
In conservation biology, it is one of the main goals to determine MVP (minimum viable population) and reserve size. These estimates that are produced via simulation, are valuable in the sense as grizzly populations are often endangered or threatened, and their population has been declining for a number of years (Wielgus, 2001).
Although the population is declining, it is still legal in North America to hunt these endangered species, as trophy hunting and is believed to be beneficial or nonthreatening for the population to grow. It is believed to protect the population due to reduced number of cannibalistic and competitive adult males, subsequently leading to the increase and survival of the cubs, hence increasing the population. However, studies have found this to be false, as removing the male grizzlies will ultimately lead to the reduction in the production of cubs, meaning that the cubs are less likely to survive, thus the population will decreases (Wielgus, 2001).
As shown in Figure 1, if stochasticity is not included, then the population will have minor fluctuations in population size, however, it will not result in the extinction of the species. Stochasticity is unpredictable spatiotemporal fluctuation in environmental conditions, which means it is the

The advantages include, having more of an insight and idea, resulting in a better conservation effort, resulting in the population to increase. This is due to the fact that the data will provide more information on how the environment will respond to stochasticity activities. However, the disadvantages of running numerous simulations is that the data is not specific, meaning it is very general. It does not outline what would happen if something irregular were to happen. It is relying on the fact that there will always be some sort of stochasticity involvement in the incline and decline of

    The Yellowstone wolves are “top- line predators”. Bears used to have to wait till spring to eat elk because that’s when they became available. Now that the wolves have come around elk is obtainable all year long. ” Researchers from the University of California at Berkeley determined that the combination of less snow and more wolves has benefited scavengers both big and small, from ravens to grizzly bears.” Wolves are bringing new possibilities for the other animals that live in the park.…

    Following this further, there was 86 hair samples taken from 2011 to 2014 that involved grizzly bear conflicts. There were relationships of 76 mother-off spring and 119 father-off spring .Within the76 mother-off spring relationships , 30.3% of off spring were considered problem bears separate from the conflict status of their mother. The father-offspring relationships, were 28.6% and considered problem bears separate from the conflict status of their father . There was not anything indicating that conflict behavior was linked to the sex of the bear.…

    Grizzly bear trophy hunts are well controlled, and do not threatened the bears continued existence in British Columbia. Over the years management programs have ensure the safety of the species with all different kinds of means. The grizzly bear trophy hunts are well controlled by programs such as limited entry hunting, which controls the number of authorized hunters in an area (Ministry of Environment, 2010, pg.1). Limited hunting entries are controlled by the government that does not allow trophy hunting in areas if the population is not at a sustainable level and only allows human-caused mortality levels to be at a maximum of 6%. This 6% also ensures that the grizzly bears existence is not threatened in British Columbia.…

    I believe that changes to living and non -living parts of an ecosystem impact population within the habitat because if you take away or put something into an ecosystem you are affecting everything around you. Especially if you put in or take out a keystone species. Keystone species are animals that other animals rely on and need to grow. So if you take away an animal that everyone relys on you are hurting all the other animals.…

    Starting in 1995 gray wolves were reintroduced into Yellowstone National Park (Ripple et al. 2013). Elk are still the primary food source of the gray wolves and grizzly bears kill elk calves and eat carcasses of other ungulates killed by the gray wolves (Ripple et al. 2013). The reintroduction of the gray wolves helped control the elk population and allowed the plants to grow more berries for the grizzly bear population to eat. After the reintroduction of the gray wolves, the amount of fruit in the grizzly bears diet increased by almost double the amount then when the gray wolves were extinct (Ripple et al. 2013). In addition, the reintroduction of the gray wolves allowed beavers and bison in the park to have higher population because there was less elk eating their food (Ripple et al. 2013).…

    Introduction The reintroduction of the Mexican Gray wolf into the southwestern United States has been a subject of large controversy in the past few decades. They first became protected by the Endangered Species Act of 1976; this species that had numbers in the thousands only a few decades earlier had become completely extinct in the United States (Southwest Wildlife). In 1960 the population dropped to seven, and yet there were still no efforts to implement their recovery as a species for 16 more years. Currently the goal of the United States Fish and Wildlife Service is to expand the population in the wild to at least one hundred (Bergman).…

    Population Growth Lab Populations of different species interact with their environment in a myriad of ways. This may also impact the population, especially concerning its size. The question trying to be answered was how changes in the amount and nature of the plant life available in an ecosystem does, in fact, influence herbivore population growth over time. Answering this question will determine which environmental factor has the greatest impact on the population growth of herbivores. In this lab the herbivores, are rabbits, and the plant life is grass and weeds.…

    Due to the Endangered Species Act of 1973, the low numbers in the grey wolf population have been closely watched and worried over. Since 1976, the grey wolf populations in Minnesota, Wisconsin, and Michigan has significantly increased. With such a large increase, there will be many effects to the local human population in these areas everyday lives. Activities, such as hunting, camping, hiking, and raising cattle, will be greatly affected. With the increase in wolf populations, it can difficult and dangerous to participate in hunting.…

    Wolves, a marvelous sight to see either in the Rocky Mountains or Yellowstone National Park. However, per Source #7, the Gray wolf was included to the U.S Endangered Species List in 1973. The government worked to increase the population and succeeded. But now in two states, Idaho and Montana, the Gray wolf has been removed from the list and can be hunted legally. Nevertheless, since there are Gray wolves in the wild, there is debate, should the Gray wolf population be protected by the government?…

    Temperature Over the last 46 years Alaska's temperature has risen about three degrees fahrenheit. This is more than two times the temperature change for the rest of the United States. In the winter the temperature has risen about six degrees farenheit which is making ice melt in the spring. If Alaska keeps warming up the average temperature could increase up to two or four degrees fahrenheit in the middle of the century.…

    National Park Rangers have incredibly important jobs when it comes to the health of an environment. Park Rangers have the ability to cause considerable change to an environment in a positive or negative way. The role of the national park ranger is to “protect, conserve, and to provide for the enjoyment of our nation 's heritage” (Maciha). National Park Rangers know better than anyone that the most basic of changes can cause an environment, or more specifically an ecosystem to crumble. The most important member of an ecosystem is a keystone species because of their influence on all of the other organisms.…

    I disagree with the idea that the Dualistic Theory entirely avoids the problems posed by the five-minute hypothesis. Huemer asserts that his theory dodges the objection because it explains why both A and B are still rational where the Preservation theory fails in doing so. The Preservation Theory claims that while rational A’s justification is preserved because he experienced the original justifying experiences, B is irrational for the lack of original experiences despite the fact that he retains the same exact memories. But the Dualistic Theory still needs to answer how one can be justified in believing their own memories. The five-minute hypothesis entails that both A and B should be doubtful of the accuracy (or even the entire content) of their memories—Perhaps A is in the same state as B but his memories are replicated from a person, Z—. Suppose we say that both A and B share the belief that they bought a new bike last week.…
