Relación entre el hábitat y el “Efecto Pardalis” en el bosque seco suroccidental del Ecuador

Abstract:

It´s estimated that more than 87 % of the Tumbes forest has been lost, or is due to patches with little connectivity, affecting the resident fauna and generating abnormal population fluctuations, such as the so-called “pardalis effect” generated when the ocelot dominates other predators in the absence of the Puma and the Jaguar. However, the dimensionality of this effect or its implicated variables have been little studied. In the present study, by means of photo- trapping the presence of this phenomenon was identified in the Cerro Blanco Protective Forest when compared with the Puyango Protective Forest, and, although the structural parameters of vegetation measured maintained little or no association with the effect, it was identified a possible preference of the ocelot for moderately conserved ecosystems with high levels of richness and diversity, as well as a high IVI for rare species and with valuations of their conservation ranging from 16 to 24.
