Minimizing conservation conflict for endemic primate species in Atlantic forest and uncovering knowledge bias



Human population is a predictor of mammal extinction risk, an indicator of conservation conflict and habitat conversion, and is thus associated with the threats to primate species. Priority areas that represent endemic primates in Atlantic Forest were identified where all counties had the same cost or where the costs of counties varied according to human population size (HPS); networks for both approaches consisted of nine counties. In the networks without human constraint, the average HPS was not higher than expected by chance alone. In the approach with human population constraint, HPS was not lower than the average of the null distribution. Although it is possible to minimize human conservation conflict, available occurrence data of endemic primates seems to be related to highly populated areas. The sum of HPS is greater in counties with some occurrence data than expected by chance. Conservation conflicts in the Atlantic Forest will continue to exist once this is the Brazilian most populous region, and data availability is directly related to counties' HPS. Field surveys are necessary to minimize Wallacean shortfall and efforts must be made to maintain the few natural areas remaining in this biome to promote the conservation of endemic primates and other biodiversity elements.
