Dietary and Feeding Differences Between Sympatric Propithecus diadema diadema and Indri indri

Lemur Diversity in Madagascar

“…Researchers have reported adult masses of 6-7 kg, which are similar to those of Indri (cf. Powzyk and Mowry 2003). The pelage is largely white, with black on the head, back of the neck and the hands and feet, and gold at the base of the tail, on the hindquarters and the limbs.…”

Ecological Correlates to Lemur Community Structure in Southeast Madagascar

“…c Data refer to research camp in northern section of Mantadia National Park (Powzyk, 1998;Powzyk and Mowry, 2003). Lemur diversity correlates negatively with agriculture intensity and altitude (Table III) for the 7 survey sites and 2 protected areas.…”

“…c Data refer to research camp in northern section of Mantadia National Park (Powzyk, 1998;Powzyk and Mowry, 2003). Rasoloarison, 2002;Sterling and McFadden, 2000;Sterling and Ramaroson, 1996).…”

Ecological and Phylogenetic Correlates to Body Size in the Indriidae

“…There are also few data on temporal and spatial variations in food quality for most indriids. The data are important because indriids range into and have differing diets in a variety of habitat types and forest fragments of differing sizes (Hemingway, 1998;Powzyk, 2003;Wright, 1995;Lehman et al, 2006). For example, Arrigo-Nelson (2005) found differences in seasonal patterns of leaf exploitation by Propithecus diadema edwardsi at logged and unlogged sites in SE Madagascar.…”

“…For example, Avahi laniger weighs only 1.03-1.32 kg and is almost exclusively folivorous (Faulkner and Lehman, 2005;Ganzhorn et al, 1985;Smith and Jungers, 1997). Conversely, the largest extant lemur, Propithecus diadema diadema (6.5 kg), has an annual diet that is composed of both young leaves (42% of total diet) and fruits (38.3% of total diet: Powzyk, 2003). Propithecus diadema diadema is sympatric throughout its range with Avahi laniger, so the differences are not likely the result of habitat variation.…”
