Spatial analysis (1987-2017) and predictive (2050) of the habitat of the San Martín Titi monkey, Plecturocebus oenanthe Thomas, in the San Martín region, Perú

Abstract

Deforestation in the Peruvian Amazon is a serious problem that harms the species that inhabit it, especially endemic species, since they have a limited range of distribution. Peru has three species of endemic primates. One of them is the San Martin Titi monkey, which has been classified as an animal in critical danger of extinction due to the threats such as deforestation and climate change. Based on the previous premise, the present study focused on the evolution of habitat in a period between 1987 to 2017 and the future habitat in 2050, based on spatial analysis techniques, presence/absence sampling and the modeling of species distribution.
The main results showed a considerable loss of coverage in the period between 1987 and 2006, but an increase in plant area between 2006 and 2017. The study also indicates the addition of two new locations of primate presence in the northern area of the study. Finally, with the future distribution model and the information about the current loss of the forests, a pessimistic scenario for the survival of the primate in the future under the influence of climate change is evident.
