Identifying priority areas for island endemics using genetic versus specific diversity - The case of terrestrial reptiles of the Cape Verde Islands

摘要: Genetic diversity is critical for conservation of endemic populations. It enhances adaptation to rapid environmental changes and persistence over evolutionary time-scales. In small isolated populations, such as on islands, this even more relevant. Nevertheless, few studies regarding the establishment protected areas (PAs) islands have taken genetic into account. The Cape Verde Islands are in a biodiversity hotspot present resource planners unique problems possibilities, hence good case study. This work primarily aims compare targeting significant units (ESUs) versus species reserve selection algorithms Verdean reptile by assessing PAs network adequacy, identifying its gaps, optimizing it based ‘realistic’ (considering inside with lower cost) ‘ideal’ all non-humanized higher potential conservation) cost scenarios. Results clearly indicate that analyses ESUs effective protection less costly terms selected area, total PAs. also most insufficiently extra needed reach targets. Surprisingly, area prioritization scenarios identical both or species. Therefore scenario should be largely followed. provides an innovative methodological framework supporting use design results assist local-scale planning.
