Hypotheses Of The Effects Of Wolf Predation :: essays research papers

Hypotheses of the Effects of Wolf de depredationAbstract This reputation discusses four hypotheses to explain the effect of wolfpredation on predate populations of wide ungulates. The four proposed hypothesesexamined are the predation limiting surmisal, the predation rulehypothesis, the predator pit hypothesis, and the stable limit cycle hypothesis. in that respect is oftentimes research literature that discusses how these hypotheses green goddess beused to interpret mingled data sets obtained from field studies. It wasconcluded that the predation limiting hypothesis rifle most study cases, but thatmore research is necessary to notice for multiple predator - multiple pitrelationships.The effects of predation can have an enormous impact on the ecologicalorganization and coordinate of communities. The processes of predation affectvirtually every species to some degree or another. Predation can be defined aswhen members of one species sap (and/or kill) those of another species. Thespecific type of predation between wolves and whopping ungulates involvescarnivores preying on herbivores. Predation can have many possible effects onthe interrelations of populations. To draw any correlations between the effectsof these predator-prey interactions requires studies of a capacious duration, andstatistical analysis of large data sets representative of the populations as awhole. Predation could limit the prey distribution and decrease abundance. Such boundary may be desirable in the case of pest species, or undesirable to someindividuals as with game animals or endangered species. Predation may also actas a major selective force. The effects of predator prey coevolution can explainmany evolutionary adaptations in both predator and prey species.The effects of wolf predation on species of large ungulates have proven to becontroversial and elusive. There have been many different manakins proposed todescribe the processes operating on populations influenced b y wolf predation.Some of the proposed implements include the predation limiting hypothesis, thepredation rule hypothesis, the predator pit hypothesis, and the stablelimit cycle hypothesis (Boutin 1992). The habit of this paper is to assess theempirical data on population kinetics and attempt to determine if one of thefour hypotheses is a better model of the effects of wolf predation on ungulatepopulation densities.The predation limiting hypothesis proposes that predation is the primary factorthat limits prey density. In this non- equilibrium model recurrent fluctuationsoccur in the prey population. This implies that the prey population does notreturn to some particular equilibrium afterward deviation. The predation limitinghypothesis involves a density independent mechanism. The mechanism might applyto one prey - one predator systems (Boutin 1992). This hypothesis predicts thatlosses of prey due to predation will be large enough to halt prey population
