摘要: The impact of habitat loss and fragmentation remaining habitats on the distribution, persistence, metapopulation dynamics plants animals is a major concern in conservation biology landscape ecology (Harris 1984, Wiens et al. 1993, Lidicker 1995, Hanski Gilpin 1997). Much our understanding how affect native populations through retrospection, speculation, or modeling rather than by direct quantification experimentation. Evidence whether not experimental observational studies corroborate substantiate predictions mathematical models equivocal (Lamberson 1994, Schumaker 1996). One reasons for this discrepancy that species within taxon often are treated as entities (i.e., all individuals “average”) individual-, sex-, species-specific differences response to taken into account (Andren Lima Zollner Some responses can be explained their behavioral systems, dispersal ability, life history, trophic level, sociality, overall changes size, connectivity, type matrix.
