The jaguar's spots are darker than they appear: assessing the global conservation status of the jaguar Panthera onca

摘要: The IUCN Red List is widely used to guide conservation policy and practice. However, in most cases the evaluation of a species using criteria takes into account only global status species. Although subpopulations may be assessed categories criteria, this rarely occurs, either because it difficult identify or effort involved. Using jaguar Panthera onca as model we illustrate that wide-ranging are assigned particular category threat based on display considerable heterogeneity within individual taxa terms level risk they face. information available species, evaluated jaguar's current geographical range its subpopulations. We identified threatened subpopulations, extent occurrence, area occupancy, population size each subpopulation. main outcome analysis was although large subpopulation persists Amazonia, virtually all others their small size, isolation, deficient protection high human density. Based approach, future efforts can prioritized for our findings recommend assessments assessors consider value undertaking at level. For jaguar, sub-global should included matter urgency.
