Item Uso de herramientas SIG en la determinación del modelo de distribución geográfica de Oncilla (Leopardus tigrinus) en Colombia, para el direccionamiento de medidas de conservación(Universidad Santiago de Cali, 2024-08-10) Echeverry Soto, Valentina; Sánchez Cuellar, Laura Maritza; Escalante Caicedo, Ana BelyLeopardus tigrinus is one of the least known felid species in Colombia, with significant information gaps due to its elusive behavior and taxonomic uncertainty. This study developed a geographical distribution model for Leopardus tigrinus in Colombia, identifying priority areas for its conservation through GIS tools. Several virtual platforms were utilized to consolidate information on the species' occurrences within the country. Additionally, the influence of ecological and environmental variables on the species' geographical distribution was analyzed on a national scale using the MaxEnt algorithm, incorporating the most relevant and least correlated variables, including WorldClim bioclimatic data, terrain (elevation and slope), and vegetation (EVI) variables. Furthermore, potential priority areas for the species conservation were identified by categorizing threatened areas within the calculated suitable habitat. The results indicate that EVI and its quadratic factor, along with Mean Annual Temperature and Precipitation Seasonality, had the most significant influence on the prediction of the distribution, underscoring the importance of conserving high-quality and dense habitats for the species' conservation. Priority areas were identified in the central and eastern Andes, particularly in the northern portion, as those requiring the most urgent attention.
