- Abstract
An understanding of current Callithrix distributions is important for species management and conservation in the wild because of widespread deforestation and the introduction, and spread, of marmosets outside their natural ranges. Here we report on a survey of the natural and introduced Callithrix distributions in five mesoregions of the southeastern Brazilian state of Minas Gerais: Metropolitana de Belo Horizonte, Sul/Sudoeste de Minas, Zona da Mata, Campo das Vertentes and Vale do Rio Doce. Our study was based on on- and off-line literature searches, e-mail questionnaires, photographic records, and field observations. The collected data were superimposed on geopolitical and vegetation maps and compared to the historical records available in mammal collections from national museums and the currently recognized natural ranges of Callithrix species. Callithrix geoffroyi and C. penicillata were widely distributed in our study area, particularly in regions and biomes where they do not occur naturally. Callithrix penicillata has apparently expanded its range into the Atlantic Forest from its native Cerrado in Central Brazil. Although not native to Minas Gerais, C. jacchus was reported at several locations in our study area. These three species were reported even in the areas of natural occurrence of C. aurita and C. flaviceps. We detected the presence of five species of Callithrix (C. aurita, C. flaviceps, C. geoffroyi, C. penicillata, and C. jacchus) in some locations of the Zona da Mata. Marmoset groups are present in some urban areas, in close contact with human populations. Marmosets are found in artificial sympatry due to the introduction of species outside their native areas of distribution. Such introductions, together with the destruction of native marmoset habitats, are a threat due to ongoing hybridization.
