BIOL 363 Lecture Notes - Lecture 20: Edge Species
Document Summary
Ecological preserves may be viewed as for large patches of land a species or even an entire community the preservation of. Factors that affect the function of a preserve. 2 impactof shape preserves should be circular to minimize the circumference introduced or pest species from surrounding urban areas and thus minimize ratio area this minimises the edge effect. 47 habitat fragmentation is important because the amount of edge habitat patch becomes smaller its spikiness matters increases while large core of a the increasing fragmentation may lead to the entire habitat consisting of edge. G climate change effects global warming changes the suitable geographic range of some species pollen records suggusts that or south over time trees migrate slowly north. 7 connections between similar patches are important for dispersion and survival of a population metapopulation 7 evolution. 8 fragmentation can increase species richness increased isolation decreased patch size and increased patch number may allow more species to exist in.
