- How is the predator community affected by low numbers of prey? How do high numbers of predators affect the prey community? What are some possible effects on other species?Predators manage the population size of their prey through two methods: consumptive effects and non consumptive effects. What are the consequences of consumptive impacts on predator population? Use an example. What are consequences of non consumptive impacts on prey populations? Use an example.Explain the Predator-Prey Population Dynamics ?
- What term is used to describe how members of different species strategize how, when, and where they will obtain resources to reduce competition? competitive reduction resource partitioning interspecies competition intraspecies competitionWhat determines whether two species will live harmoniously together, or whether competition will result in the extinction of one of them and the survival of the other?Both hawks and owls feed on small mammals to sustain their respective populations without causing competitive exclusion. How can this work when both species live in the same geographic area?
- What happens as a population approaches carrying capacity?How can we determine whether predation is controlling the size of a population? What are the conditions that promote coexistence between predators and prey? please answer bothIn the Lotka-Volterra predator-prey equations, the term a b N prey N predator describes: The rate at which predators eat prey The rate at which new predators are added to the predator population The rate at which the predator population increases over time The intrinsic growth rate of the prey population
- Why do managers try to maintain populations of fish and game species at about half their carrying capacity?Which of the following is NOT an assumption of the basic Lotka-Volterra model of predatory-prey dynamics? Prey are the primary food source for the predators There is no immigration or emigration of predators or prey All prey in the population are accessible to predators, e.g. there are no prey refuges Prey population growth can be limited by food and other resources Predators are the main cause of mortality for the preyDefine predation. How does the predator-prey relationship differ from the parasite-host relationship? Why is the evolutionary race be-tween predator and prey one that the predator cannot afford to win?
