Xyomara's doctorate thesis highlighted how conservation strategies in fragmented landscapes affects the occupancy, abundance and in more detail the group density, size and composition of the primate species studied, depending on the scale at which conservation actions are taken by using a group of primate species in the Colombian Llanos. This thesis offers a comprehensive analysis of the importance of a landscape approach in primate studies to assess the effects of landscape change at multiple scales. Ecological and behavioral studies of new world primates in fragmented and continuous areas are the main research interests for Xyomara. Currently, Xyomara is a consultant for the woolly monkey monitoring program at the Amacayacu National Park in the Colombian Amazon.
