Assessing the umbrella value of a range-wide conservation network for jaguars (Panthera onca).

摘要: Umbrella species are employed as conservation short-cuts for the design of reserves or reserve networks. However, empirical data on effectiveness umbrellas is equivocal, which has prevented more widespread application this strategy. We perform a novel, large-scale evaluation umbrella by assessing potential value jaguar (Panthera onca) network (consisting viable populations and corridors) that extends from Mexico to Argentina. Using richness, habitat quality, fragmentation indices ~1500 co-occurring mammal species, we show corridors overlap substantial amount percentage high-quality mammals performs better than random networks in protecting high-quality, interior habitat. Significantly, an would not have been noticeable had focused richness our sole metric utility. Substantial inter-order variability existed, indicating need complementary strategies certain groups mammals. offer several reasons positive result document, including large spatial scale analysis focus multiple metrics effectiveness. Taken together, results demonstrate regional, single-species strategy can serve effective larger community should help conserve connectivity suite Current future range-wide planning exercises other predators may therefore important benefits.
