Project: Matrix use by the black lion tamarin, Leontopithecus chrysopygus, in the municipality of Guarei, Sao Paulo
Abstract: Many primate species live in fragmented landscapes, where their ability to explore different types of matrix for resources or dispersal among fragments contributes to the survival and persistence of the species. Therefore it is extremely important to assess how primates deal with the matrix and if they are able to use it for their advantage. The black lion tamarin (Leontopithecus chrysopygus, Callitrichidae) is endemic of the Sao Paulo State, and presents a highly fragmented distribution area. Our study will determine their use of the matrix in the municipality of Guarei that is marked by intense farming and agriculture and where the occurrence of the species was recently confirmed. More specifically, we will intend to determine the degree of resistance of the different types of matrix in the region (roads, pastures, orchards and monocultures), evaluate the context of matrix crossings, and determine whether black lion tamarins use some resources within it. Events of matrix use and crossing are rare and difficult to sample. Therefore, interviews with residents and mapping of registered events will enable us to identify areas of the species occurrence, the context of matrix crossings and the distances traveled within it. Our research will enable the elaboration of a functional connectivity map with the aim to better understand the species relationship with the landscape and the possible consequences on gene flow and population viability in the region. The conclusions of this project should enhance further studies in the municipality and serve as a basis for the development of conservation initiatives and management of populations of black lion tamarin in Guareí.
