          Abstract

          O clima e a vegetação são conhecidos determinantes das distribuições geográficas de várias espécies de mamíferos. Neste estudo foi testada a importância do clima e da vegetação como fatores limitantes da distribuição geográfica do sagui Callithrix flaviceps (Thomas, 1903). As análises com o clima foram feitas a partir de nove fatores climáticos, estimados para cada localidade de ocorrência da espécie em estudo. Métodos não lineares (regressão logística) foram usados para modelar a distribuição geográfica a partir dos dados climáticos. As análises de vegetação foram feitas a partir do mapa digital das eco-regiões. A sobreposição dos modelos de distribuição climática com os mapas dos tipos de eco-regiões sugeriram que estes dois fatores são limitantes na distribuição geográfica de Callithrix flaviceps. Foi ainda discutida a importância das interações interespecíficas como limitantes da distribuição geográfica de Callithrix flaviceps.

          The climate and the vegetation are known determinant of the geographical range of several species of mammals. Here it was analized the role of the climate and the vegetation as limits of geographical range of the marmosets Callithrix flaviceps (Thomas, 1903). For each locality of occurrence, averages estimates of nine climatic variables and ecoregion data were recorded. A non-linear method (logistic regression) was used to model the climatic geographical distribution. Vegetation analysis was done with data from the digital map of ecoregions. The overlap of the climatic distribution map with ecoregion map suggested that both factors have importance in the limits of the geographical range of C. flaviceps. The role of interspecific interactions as limits to geographical range of C. flaviceps is also discussed.
