Les hommes ont oublié cette vérité. Mais tu ne dois pas l'oublier, dit le renard. Tu deviens responsable pour toujours de ce que tu as apprivoisé.

Distribution and habitat use of invasive dogs in Colombia

Manjarrés Rodríguez, T. S. (2015). Distribución y uso de hábitat del perro (Canis familiaris) en la cuenca alta del río Otún (Risaralda-Colombia).Trabajo de grado presentado para optar al titulo de: Magister en Conservación y Uso de la Biodiversidad (Modalidad de investigación)
The dog (Canis familiaris) is a alien specie that when is present in natural areas get to interact with wildlife as a competitor, predator and transmitter of disease. The present study identified through the
tracking the dog abundance index and the dog selection of habitat types, its density with the probability density Kernel-ArcGis 10 and its potential distribution related with environmental
variables that limit or favor he dog presence through the MAXENT program. How results the dog
was found in both vegetation types studied (secondary forest and grassland). The dog got a high
density and abundance in the study area, surpassing the abundance of wildlife registered. The
Bonferroni interval showed that the dog and the fox (Cerdocyon thous) shared the same types of
habitat. The variables that favors their presence were the proximity to house and roads turning the
upper basin of the river Otun in vulnerable to the constant invasion of this specie.
