Species composition in fragmented forests: Conservation implications of changing forest area

摘要: An important aspect of forest fragmentation is the ensuing change in area and impact this has on species number composition. Quantifying an step prioritizing fragments for biodiversity conservation. Species–area curves from isolated Ghana, West Africa, show that large forests contain greatest tree species. Moreover, additional found within larger follow a predictable pattern rather than acting as random complements community. The proportion rare increases with area, but common form stable foundation comprising around two-thirds total complement. As increases, edge effects decrease relative proportions evergreen shade-tolerating increase respect to deciduous pioneers. use species–area determine capacity small remnants support diversity should consequently be assessed component Increasing will result loss valuable portion ecosystem: These more effectively preserved reserves.
