Home range of a Geoffroy's marmoset group, Callithrix geoffroyi (Primates, Callitrichidae) in South-eastern Brazil

Abstract: The home range of one group of the Geoffroy's marmoset (Callithrix geoffroyi) was studied in a fragment of the Atlantic Forest in south-eastern Brazil, between February 1993 and January 1994. The total home range was 23.3 ha and the area used in the dry season was significantly larger than that of the wet season. The smallest distance travelled by group was 480 m/day in May and the longest was 1,980 m/day in March, but with no significant differences between seasons. The total home range used for this species … Show more

“…Based on the diet of the dolphins and on the seasonal variation of abundance of dominant prey types (especially fish from the Engraulidae Family), it has been hypothesized that the greater spatial requirements of the estuarine dolphins in the cold seasons were due to a lower abundance of food resources, whereas the opposite occurs in the summer (Daura-Jorge, 2003;Wedekin, 2003;Daura-Jorge et al, 2004). The negative relationship between the abundance of major food items and the size of the area used by individuals or groups has also been found in primates (Passamani and Rylands, 2000;Castro, 2003) and in one small cervid species (Tufto et al,996).…”

“…For this reason, even considering that occasional large-scale individual movements and dispersal may occur, the group home-range concept was applied in the present study in the same way as it is applied in some primate social group studies (e.g. Stacey, 986;Passamani and Rylands, 2000;Castro, 2003).…”

“…Thus, M. rufus, C. major, and D. madagascariensis should be omnipresent in forest fragments. Insectivores may prefer forest edges because of abundant insect prey in this microhabitat (Passamani and Rylands, 2000;Spironello, 2001). Based on these assumptions, omnivores with a diet composed of insects (M. rufus) should range nearer to forest edges than omnivores that rarely eat insects (C. major and D. madagascariensis).…”

“…Many researchers have investigated the effects of forest fragmentation on primate biogeography (Jones, 1997;Estrada et al, 1999;Oka et al, 2000;Onderdonk and Chapman, 2000;Passamani and Rylands, 2000;Ganzhorn et al, 2001;Ganzhorn and Eisenbeiss, 2001;Evans et al, 2003;Ganzhorn et al, 2003;Marsh, 2003;Norconk and Grafton, 2003;Sussman et al, 2003;Baranga, 2004;Mbora and Meikle, 2004;Chapman et al, 2005;Harcourt and Doherty, 2005). Larger fragments tend to have more habitats and larger total population limits, which in turn allow them to host more species (Rosenzweig, 1995).…”
