| ecology and conservation of the crowned lemur, lemur coronatus, at ankarana, n. madagascar. with notes on sanford's lemur, other sympatrics and subfossil lemurs. | forests of ankarana limestone massif in northern madagascar support one of the largest and least disturbed populations of crowned lemurs, lemur coronatus. this paper reports a preliminary study of the ecology of this species in the ankarana special reserve conducted at the end of the dry season in 1986, with additional information collected a year later. crowned lemurs occur in very high densities in the semi-deciduous canopy forest and this probably represents a dry season refuge for the specie ... | 1989 | 2807091 |
| dietary patterns in perrier's sifakas (propithecus diadema perrieri): a preliminary study. | some lemur species range into only one habitat type, whereas others range into a variety of habitats. because plant community structure can differ between habitats, dietary patterns may vary for conspecific groups of primates that range into more than one type of habitat. the goal of our study was to determine how habitat variation influences dietary patterns in perrier's sifakas (propithecus diadema perrieri) that range into both dry and riparian forests in northern madagascar. we collected 542 ... | 2004 | 14983469 |
| ecogeographic size variations in sifakas: a test of the resource seasonality and resource quality hypotheses. | ecogeographic size variations have been documented in some but not all sifakas. few morphometric or body weight data have been available for two critically endangered subspecies of diademed sifakas: perrier's sifakas (propithecus diadema perrieri) and silky sifakas (propithecus diadema candidus). the objectives of our study were to determine size variations in sifakas and if these variations are related to resource quality and/or resource seasonality. p. d. perrieri and p. d. candidus were captu ... | 2005 | 15386235 |
| climate change and human colonization triggered habitat loss and fragmentation in madagascar. | the relative effect of past climate fluctuations and anthropogenic activities on current biome distribution is subject to increasing attention, notably in biodiversity hot spots. in madagascar, where humans arrived in the last ~4 to 5,000 years, the exact causes of the demise of large vertebrates that cohabited with humans are yet unclear. the prevailing narrative holds that madagascar was covered with forest before human arrival and that the expansion of grasslands was the result of human-drive ... | 2017 | 28488335 |
