Effects of Wolf Predation

This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates. The four proposed hypotheses examined are the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. There is much research literature that discusses how these hypotheses can be used to interpret various data sets obtained from field studies. It was concluded that the predation limiting hypothesis fit most study cases, but that more research is necessary to account for multiple predator – multiple prey The effects of predation can have an enormous impact on the ecological organization and structure of communities. The processes of predation affect virtually every species to some degree or another. Predation can be defined as when members of one species eat (and/or kill) those of another species. The specific type of predation between wolves and large ungulates involves carnivores preying on herbivores. Predation can have many possible effects on the interrelations of populations. To draw any correlations between the effects of these predator-prey interactions requires studies of a long duration, and tatistical analysis of large data sets representative of the populations as a whole. Predation could limit the prey distribution and decrease abundance. Such limitation may be desirable in the case of pest species, or undesirable to some individuals as with game animals or endangered species. Predation may also act as a major selective force. The effects of predator prey coevolution can explain many evolutionary adaptations in both predator and prey species. The effects of wolf predation on species of large ungulates have proven to be controversial and elusive. There have been many different odels proposed to describe the processes operating on populations influenced by wolf predation. Some of the proposed mechanisms include the predation limiting hypothesis, the predation regulating hypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis (Boutin 1992). The purpose of this paper is to assess the empirical data on population dynamics and attempt to determine if one of the four hypotheses is a better model of the effects of wolf predation on ungulate population densities. The predation limiting hypothesis proposes that predation is the primary factor that limits prey density. In this non- equilibrium model recurrent fluctuations occur in the prey population. This implies that the prey population does not return to some particular equilibrium after deviation. The predation limiting hypothesis involves a density independent mechanism. The mechanism might apply to one prey – one predator systems (Boutin 1992). This hypothesis predicts that losses of prey due to predation will be large enough to Many studies support the hypothesis that predation limits prey density. Bergerud et al. (1983) concluded from their study of the interrelations of wolves and moose in the Pukaskwa National Park that olf predation limited, and may have caused a decline in, the moose population, and that if wolves were eliminated, the moose population would increase until limited by some other regulatory factor, such as food availability. However, they go on to point out that this upper limit will not be sustainable, but will eventually lead to resource depletion and population decline. Seip (1992) found that high wolf predation on caribou in the Quesnel Lake area resulted in a decline in the population, while low wolf predation in the Wells Gray Provincial Park resulted in a slowly increasing population. Wolf predation at the Quesnel Lake area remained high despite a fifty percent decline in the caribou population, indicating that mortality due to predation was not density-dependent within this range of population densities. Dale et al. (1994), in their study of wolves and caribou in Gates National Park and Preserve, showed that wolf predation can be an important limiting factor at low caribou population densities, and may have an anti-regulatory effect. They also state that wolf predation may affect the distribution and abundance of caribou populations. Bergerud and Ballard (1988), in their interpretation of the Nelchina caribou herd case history, said that during and immediately following a reduction in the wolf population, calf recruitment increased, which should result in a future caribou population increase. Gasaway et al. (1983) also indicated that wolf predation can sufficiently increase the rate of mortality in a prey population to prevent the population's increase. Even though there has been much support of this hypothesis, Boutin (1992) suggests that â€Å"there is little doubt that predation is a limiting factor, but in cases where its magnitude has been measured, t is no greater than other factors such as hunting. † A second hypothesis about the effects of wolf predation is the predation regulating hypothesis, which proposes that predation regulates prey densities around a low-density equilibrium. This hypothesis fits an equilibrium model, and assumes that following deviation, prey populations return to their pre-existing equilibrium levels. This predator regulating hypothesis proposes that predation is a density-dependent mechanism affecting low to intermediate prey densities, and a density-independent mechanism at high prey densities. Some research supports predation as a regulating mechanism. Messier (1985), in a study of moose near Quebec, Canada, draws the conclusion that wolf-ungulate systems, if regulated naturally, stabilize at low prey and low predator population densities. In Messier's (1994) later analysis, based on twenty-seven studies where moose were the dominant prey species of wolves, he determined that wolf predation can be density-dependent at the lower range of moose densities. This result demonstrates that predation is capable of regulating ungulate populations. Even so, according to Boutin (1992) ore studies are necessary, particularly at high moose densities, to determine if predation is regulatory. A third proposal to model the effects of wolf predation on prey populations is the predator pit hypothesis. This hypothesis is a multiple equilibria model. It proposes that predation regulates prey densities around a low-density equilibrium. The prey population can then escape this regulation once prey densities pass a certain threshold. Once this takes place, the population reaches an upper equilibrium. At this upper equilibrium, the prey population densities re regulated by competition for (and or availability of) food. This predator pit hypothesis assumes that predator losses are density-dependent at low prey densities, but inversely density-dependent at high prey densities. Van Ballenberghe (1985) states that wolf population regulation is needed when a caribou herd population declines and becomes trapped in a predator pit, wherein predators are able to prevent caribou populations from increasing. The final model that attempts to describe the effects of predation on prey populations is the stable limit cycle hypothesis. This hypothesis proposes that vulnerability of prey to predation depends on past environmental conditions. According to this theory, individuals of a prey population born under unfavorable conditions are more vulnerable to predation throughout their adult lives than those born under favorable conditions. This model would produce time lags between the proliferation of the predator and the prey populations, in effect generating recurring cycles. Boutin (1992) states that if this hypothesis is correct, the effects of food availability (or the lack of) should be more subtle than outright starvation. Relatively severe inters could have long- term effects by altering growth, production, and vulnerability. Thompson and Peterson (1988) reported that there are no documented cases of wolf predation imposing a long-term limit on ungulate populations independent of environmental influences. They also point out that summer moose calf mortality was high whether predators were present or not, and that snow conditions during the winter affected the vulnerability of calves to predation. Messier (1994) asserts that snow accumulation during consecutive winters does not create a cumulative impact on the nutritional status of deer and All of the four proposed theories mentioned above could describe the interrelationships between the predation of wolves and their usual north american prey of large ungulate species. There has been ample evidence presented in the primary research literature to support any one of the four potential models. The predation limiting hypothesis seems to enjoy wide popular support, and seems to most accurately describe most of the trends observed in predator-prey populations. Most researchers seem to think that more specific studies need to be conducted to find an ideal model of the effects of predation. Bergerud and Ballard (1988) stated â€Å"A simple numbers argument regarding prey:predator ratios overlooks the complexities in multi-predator-prey systems that can involve surplus killing, additive predation between predators, enhancement and interference between predator species, switch over between prey species, and a three-fold variation in food consumption rates by wolves. † Dale et al. (1994) stated that further knowledge of the factors affecting prey switching, such as density-dependent changes in vulnerability within and between prey species, and further knowledge of wolf population response is needed o draw any firm conclusions. Boutin (1992) also proposed that the full impact of predation has seldom been measured because researchers have concentrated on measuring losses of prey to wolves only. Recently, bear predation on moose calves has been found to be substantial, but there are few studies which examine this phenomenon (Boutin 1992). Messier (1994) also pointed out that grizzly and black bears may be important predators of moose calves during the summer. Seip (1992), too, states that bear predation was a significant cause of adult caribou mortality.

Violations under American Disability Act Case Study

Violations under American Disability Act - Case Study Example The foregoing violations shall be discussed individually. First, the American Disability Act (ADA) â€Å"applies to disabilities that affect a major life activity, and those areas of coverage are vision, mental and motor skills, ability to care for one’s self and commute to employment†. In the case of Miss Clark, the fact that she is blind has been known to the company for a long time, as she holds the Vice-President position. Even though she is suffering from visual impairment, it did not prevent her from fulfilling her duties and responsibilities as the Vice-President of the company. However, due to her physical disability, the company refused to promote her to the position of Senior Vice-President because they think that she is not capable enough to carry-out the functions of an SVP. In spite of this physical defect, she has remained loyal to the company and worked for them in several years. Without a doubt, there is a clear violation of the law when the employer pre vented the career advancement of Miss Clark by denying her of the position of the Senior Vice-President. ... f the major life activities of such individual; Second: A record of such impairment, or being regarded as having such impairment; and Third: Accordingly, to fall within this definition, one must have an actual disability, have a record of disability or be regarded of having one. Verily, in the light of the justifications provided by law, Miss Clark has a valid cause of action against her employer as the above requisites have been complied with and she can file a claim against her employer. The employers must take judicial of the fact that both the state laws and the federal laws give protection to employees who have been victims of discrimination because of a disability, and entitles them to file claims for damages. This is pursuant to the principle of â€Å"disparate treatment enunciated in the case of Raytheon Vs. Hernandez (540 U.S. 44 (2003)  298 F.3d 1030), where the Supreme Court held that in addition that disparate impact claims are also available to workers based on facial ly neutral policies that impact qualified individuals with disabilities differently than workers without disabilities†. Another glaring violation committed by her employer is against the provisions of â€Å"The Employee Retirement Income Security Act of 1974, or ERISA. The law was enacted to â€Å"protect the employees’ justified expectation of receiving the benefits their employers promise them, and ensures that employees will not be left empty-handed once employers have guaranteed them certain benefits upon retirement† (Bennet-Alexander and Hartman 742). Under ERISA, Miss Clark has a legal standing to sue her employer for illegally termination when she was forced to resign and accept diminished retirement benefit package being offered by the company, which she later on refused for violations

Team Performance Measurement in the Health Care Services Essay

Team Performance Measurement in the Health Care Services - Essay Example These periodic performance assessments are deemed important in every line of work, even more so in jobs that deal with life and death situations, as methods of bringing care to the sick and injured can be improved by taking the outcomes of previous performance assessments into consideration (Sundar, Sundar, Pawlowski, Blum, Feinstein, & Pratt, 2007). By creating clear and realistic goals based on the attainability of meeting or exceeding previous goals, patients and members of the community can get an assurance that the services being given by health care personnel in health facilities can either remain as satisfactory as before or become even better. Thus, it is important that there is a proper monitoring of the performance of teams and their members to maintain quality services to all stakeholders. However, while monitoring of performance measures and keeping track of goals sounds fairly simple, doing the actual thing can be daunting and even labor-intensive. It can be expected that some problems and challenges could arise during the evaluation itself, such as questioning the reliability of performance measures as well as the accuracy of goals which depend on quantitative characteristics and could bring challenges in the appropriate assessment of a team’s performance (Zeiss, 2002). Self-monitoring for each member normally does not pose a problem, even among team members that have other ancillary functions apart from their specific job functions, but when it comes to feedback from other members of the team, interpersonal problems between the evaluated party and the evaluating party could affect the outcomes of total scoring such as supervisory and peer evaluations, which could lead to resentments with each other if not addressed promptly (Reader, Flin, Mearns, & Cuthberts on, 2009; Shi, 2010).

Arts Advocacy Statement and Pamphlet - Essay Example Artistic aptitude is an amazing ability and it is very significant for our children for their better mental approach. Art helps to enhance the childrens ability to have a better perception of the world and tends to get them to adopt a better way of communication and expression. Art helps children to make an open appearance and reveal their hidden talent and skills. Therefore, for a successful and flourishing life track, you must try to develop artistic skills in your child. Now a question arises as to what are the important factors that are necessary for the artistic development in your child. When your child starts performing certain activities, you need to develop art in his activities. Every child has a hidden artist in their inner self and parents or teachers can examine very well what kind of artistic intuition is growing within a child. Some children love to make drawings and some love to use brushes to handle colours. Some love music and few have the ability to be great composers. So every child has his/her own inclination towards various categories of art. The four disciplines of art have a diverse arrangement among artistic abilities such as drawing, print-making, painting, drama, music and dance. All these classifications are the basic skills that can be found in oneself to create a better perception of life. Home is the first basic learning institute and whatever skills a child uses to learn at home, no institute around the world could impart these skills to children. To develop art in your child and have your child able to have a better overview of any situation in life, you need to develop your child’s interest in all of the above given mediums of art. Education is an entirely different thing, but any skill or talent in a child can add more to his education with the help of artistic qualities. Art is the thing that never cares for substantial measures and children also

Leadership Theories - Essay Example (i) They must have extensive expression, which they exercise to cover the thought of possessing a proof of triumph, whereby the person in question will have the ability to organize and lead others in a more organized manner, also being with the power to take and handle project. (iii) Sincerity and reliability, the leader has the behavior of taking an honest depiction of himself or herself, so that the people they lead can value and obey them. These will make the organization to be effective in performance as the duties will be done with less supervision. (Ajzen 1991). (v) Understanding of the industry is important for reliability, hence when a leader posses such characters in him or her, the organization will move forward in the right direction as the leadership of the organization will be reliable to the people and the environment. (vii) Hospitability, where leaders will have the skill to search for satisfying communal associations, hence they will be harmless, thoughtful and sensitive. The attribute of headship focuses on the head, but not the people he or she leads. The head shows a definite set of attributes to be an influential and successful manager. The leader – member hypotheses can be viewed using Meta – Assessment. The connection linking the leader-member exchange theory is investigated, as are matters associates to the theory. (Gernstner, 1997). Reports recommend that important connection between the hypotheses and work presentation, fulfillment with administration, general fulfillment, obligation, duty divergence, duty clearness, and capability of the people involved, therefore as an executive, he or she is required to undertake the above named attributes to fulfill the potential of the organization. The Leader – Member Exchange hypotheses tries to explain on how the heads and managers build up connections with their subordinate staff; and it clarifies how those linkages can lead to escalation

Global Assessment of Haiti Part 2 Research Paper

Global Assessment of Haiti Part 2 - Research Paper Example Pneumonia and Influenza are the major diseases that cause a lot of deaths of the Haitian population (World Fact book, 2013). The country is vulnerable to environmental impacts like harsh climatic changes and stressors of the environment like hurricanes and earthquakes. The country has presidential system and the national assembly is bestowed with law making processes. Use of voodoo doctrines is part and parcel of the Haitian population and the whole population is strong believers of the Roman Catholic. Lack of proper planning possesses a lot of challenge to the health sector of this country; because of the poor organization, most of the health care management is conducted by NGOs like Cuban Brigade and other bodies like MSF. Because of the natural calamities like earthquakes, the free medical services offered by the government had to stop because the government became bank craft and could no longer provide for the needs of the population. The old generation and the youngsters are the most susceptible members of the society based on outbreak of diseases like cholera. The case of cholera has been epidemic due to the poor hygiene and sanitation in the country. The vivid impact of the health issues is death among the vulnerable population. Due to the escalation of the health standards in the country, many international bodies have decided to offer a helping hand and some of such bodies are Pan American Health Organization (PAHO) and Partners in Health Organizations (PIH). These international bodies have embarked on vaccination programs against cholera to reduce its escalating effects. Another international body that has played a major role is UNICEF. This body has been engaged in vaccination programs to reduce the spread of cholera and other water-borne diseases. Haiti health concern with millennium development goals Some of the goals of the millennium development are eradication of extreme poverty rate and hunger, reduction of mortality rate among children below t he age of five years, improvement of maternal health care, and combating HIV/AIDS and malaria diseases (Adam et al., 2006). Based on the findings of Haiti case, nearly all the millennium goals have not been met. Haitian population still suffers from poverty since most of them live below the poverty line and this therefore, means that the first goal of eradication of poverty by millennium development has not been achieved. The second goal is reduction of mortality rate among children below the age of five years and this goal has equally not been achieved because the most vulnerable people in the Haitian population are the children below the age of five years. The country can be said to be far away from achieving the millennium goals because of their poor health organization and failure to eradicate water-borne disease like cholera. For the country to attain these goals then a lot of changes should be done on the health sector. The government should be able to contain the health situa tion and it should be able to give provisions to basic medical requirements and also cleaning drinking water for the citizens. Without these changes then the country will still be far away from achieving the highlighted goals. Three levels of prevention Levels of prevention can be broadly classified into three categories: primary, secondary, and
