[Diet of (Tenrecidae) in northeast Madagascar].

Herein we provide a dietary analysis using stomach contents of (G. Grandidier, 1899), a poorly known species of shrew tenrec, in the dense lowland moist evergreen forest of the Marojejy National Park and human modified habitats in the peripheral zones. We specifically examine the arthropods consumed by this species and variation related to season, habitat type, sex and age of individuals.

Spatial distribution of dominant arboreal ants in a malagasy coastal rainforest: gaps and presence of an invasive species.

We conducted a survey along three belt transects located at increasing distances from the coast to determine whether a non-random arboreal ant assemblage, such as an ant mosaic, exists in the rainforest on the Masoala Peninsula, Madagascar. In most tropical rainforests, very populous colonies of territorially dominant arboreal ant species defend absolute territories distributed in a mosaic pattern. Among the 29 ant species recorded, only nine had colonies large enough to be considered potentially territorially dominant; the remaining species had smaller colonies and were considered non-dominant.
