Document Summary
Predation pressure - protective shelters from predators become limiting, predator pressure may increase with increased prey density. Realized niche - can be outcompeted as the other species also used the resources smaller than fundamental. Fundamental niche- without competition from other species. Connell 1950"s: chthamalus is a crustation that is on the top of the rock when the tide is high it is underwater but when it is low it is out of water, longest penis of any species. Thus it does better in its fundamental niche than its realized niche. Natural selection favours individuals that do not compete. Predation pressure - protect sheets from predators become limiting, predator pressure may increase with increased prey density, predator preformancemay increase with practice. Mushroom ex performance of nding them can ge thigh. Disease & parasitism - lungworm in rocky mountain bighorn sheep. Lots of people around, the predator may get someone else and not you.
