A range-wide model of landscape connectivity and conservation for the jaguar, Panthera onca

摘要: Abstract Large, wide-ranging carnivores face greater threats and more persistent declines than most other mammal species. An important conservation tool for these has been range-wide priority-setting exercises that have helped identify critical key populations. However, such often fail to functional movement corridors or account genetic connectivity. We present a new model jaguar ( Panthera onca ) uses geographic information system (GIS) expert input create dispersal cost surface least-cost connecting the 90 known populations across jaguar’s range. Results indicate 78% of historic range, an area approximately 14.9 million km 2 , still holds potential dispersal. identified 182 between populations, ranging from 3 1607 km in length; 44 are characterized as being immediate concern due their limited width, thus high severed. Resultant maps, displaying priority corridors, used direct field-based research efforts. Field assessment refinement is ongoing. This first attempt implement holistic large carnivore
