New data on the status and distribution of the bush dog (Speothos venaticus): Evaluating its quality of protection and directing research efforts

摘要: Abstract The bush dog ( Speothos venaticus ), listed as CITES Appendix 1 – vulnerable, is a small (5–6 kg), rarely seen canid from Central and South America. World Conservation Union Canid Specialist Group (IUCN CSG) recommended that research with this species focus on their basic ecology so data-driven conservation strategy can be formulated. Information the dog, however, has been lacking since standard field techniques have had little or no success species. S. Status Distribution Survey was developed in an attempt to use indirect methodologies determine dog’s status wild, its current distribution, identify ecological needs by correlating habitat types sightings. responses literature generated database 399 historic locations recorded between 1834 2004. These locational records were used update species’ range extent map, important planning tool. With year precision of data accounted for, we analyzed land coverage at known where dogs historically reported evaluate likelihood persists area today. In addition, these provided training for generation potential distribution maps (i.e., areas occupancy) using niche modeling Maximum Entropy) bioclimatic data. analyses revealed 20% are associated fragmented altered habitat. results allowed re-evaluated require more intensive protection identified.
