Document Summary
Exclusion or inclusion experiments: usually by cages or fences (to ensure space isn"t being disturbed by other species, removal of predators, manipulate presence or density of predators, experimental controls. If depressing number of foxes by having more coyotes, there were more eggs: ex. In new zealand, too many rabbits, tried to introduce cats to kill off rabbits: cats went for flightless birds instead since they were easier to catch and so birds went extinct. Some predator-prey systems circle over time: ex. Snowshoe share and lynx circle every 9-10 years. It has been very challenging to unravel the multiple causes for this cycle. Predator response: what makes some predators efficient in controlling prey populations and others not, numerical response increases in density of predator via reproduction. Simple predator-prey system based on: limited by defense of territories. What about indirect effects of predation: competition among predators, ex.
