Use of space by neotropical marsupial Didelphis albiventris (Didelphimorphia: Didelphidae) in an urban forest fragment

Abstract: A population of the Neotropical marsupial Didelphis albiventris (Lund, 1840) living in an urban forest fragment was studied. Population structure and the influence of sex and age on two variables related to habitat use (Daily home range - MCP and Habitat use intensity - UI) obtained by the spool-and-line technique were analysed. There were 20 males and 29 females studied (N = 49). No sexual dimorphism was apparent in adult individuals. There were 16 males and 24 females tracked using the spool-and-line device.… Show more

“…That suggests that the species are closely related, and their habits are thought to be similar, as the scansorial movements and the frugivory-omnivory diets (Emmons and Feer, 1997). Moreover, D. albiventris female use the interior of remnants regularly when not in sympatry with D. aurita (Almeida et al, 2008;Cáceres et al, 2008;Sanches et al, 2012;Talamoni and Dias, 1999;R.F.

“…This result may indicate that subadult males utilize smaller areas, but more intensively, incorporating the use of the vertical stratum in their activities, as observed for some subadult marsupials (CUNHA & VIEIRA 2005, ALMEIDA et al 2008. Subadult females use larger areas, but less intensively, moving predominantly on the litter.…”

“…Adult males had larger DHRs than subadults. This kind of difference has been attributed to the differing energy requirements among different individuals (MARQUET et al 2005, ALMEIDA et al 2008, VIEIRA & CUNHA 2008. However, the DHR expresses the spacing between the individuals and their daily movements, which can be viewed primarily as a result of hierarchical, demographic and economic processes (PRIOTTO et al 2004, REHMEIER et al 2004, SKVARLA et al 2004, MITCHELL & POWELL 2012.…”

“…Uma provável causa para a ausência de capturas pode ser um viés de amostragem, pois as armadilhas usadas não têm tamanho adequado para a captura de espécies do porte de Didelphis albiventris. Entretanto, é importante ressaltar que pode ser muito comum em áreas de Mata Atlântica muito degradas (Caceres 2000, Almeida et al 2008), e em áreas de Cerrado onde a densidade média varia de 1 a 6 ind/ha (Mares e Ernest 1995).…”
