Effectiveness of protected area networks in representing freshwater biodiversity: the case of a Mediterranean river basin (south‐eastern Spain)

摘要: 1. Biodiversity is probably at greater risk in freshwater systems than other ecosystems. Although protected areas (PAs) play a vital role the protection of biodiversity and are mainstay most conservation polices, coverage by existing PA networks often inadequate few reserves created that take into consideration biota. 2. In this paper an attempt made to address performance context using data records for water beetles Mediterranean river basin. 3. Although present PAs study area cover relatively high number beetle species, distribution extent still or insufficient protect biodiversity, especially species concern. 4. Alternative area-selection methods (hotspots complementary) were more efficient representing beetles. Within these, complementarity was approach, able represent all significantly lower current network. On hand, future Natura 2000 Network will result great increase total land as well represented. 5. Unfortunately, occurrence within not guarantee long-term survival because disturbances occur outside park boundaries. Thus, whole-catchment management natural-flow maintenance indispensable strategies conservation. Copyright © 2006 John Wiley & Sons, Ltd.
