Document Summary
Cyclic population dynamic snowshoe hares and lynx prey populations are influenced by: food availability, consumption by predators, non- consumptive effects of predators lynx and hares have a good record of over 200 years from hunting. No single theory is enough to explain the cyclic nature of lynx and hares, a study was done which showed that both factors: food and predation have substantial impact on populations. Sustainable management requires: ecological knowledge/ understanding knowledge of species. Fisheries may collapse due to selfishness inadequate ecological knowledge improper management. When modelling systems be careful when looking at dynamics, many factors play into population ecology. Modelling is important but must be cautiously done. Competition: the relationship in which at least two species are negatively affected. Organisms may compete for: food, shelter, territories, mates, resources etc. Intraspecific competition is competition between the same species bighorn sheep fighting for mates. Interspecific competition is competition between different species wolves/coyotes fighting over carcass.
