BIO 2129 Lecture Notes - Metapopulation, Dynamic Equilibrium, Biogeography
Document Summary
Neutral with respect to species identity, all species are treated exactly the same: the closer the island, the more frequent immigration can be and the more rapidly they can get there. Decline as you get farther away: harder to find island and death increases because farther from mainland: dynamical process, change rate, change dynamical process that effects species. Larger pop is on big islands: chances are that pop wont be going icstinct. Intersection of curves is where you expect biodiuversity to gtow. A lot of landscape is fragmented, the some that does remain looks like islands, surrounded by urban areas, and human dominated landscapes. Maintain natural processes is more likely in the large reserve (lasts longer) Increased presence of edge effects within small reserve, pervades parks to a larger degree than in the large park: round reserve is better than linear minimizes ratio of edge relative to the area of the park.
