Evidence for female dominance in the Milne‐Edwards' sportive lemur ( Lepilemur edwardsi )
Female dominance over males is more frequent in Malagasy lemurs than in other primate clades, but patterns of female–male dominance vary among species, and few data are available for one particularly species‐rich genus, Lepilemur . We investigated the types, temporal distribution, and outcome of female–male agonistic conflicts in the Milne‐Edwards' sportive lemur ( Lepilemur edwardsi ). Ten L. edwardsi belonging to five social units were equipped…
Feeding Ecology and Regurgitation–Reingestion Behavior of the Critically Endangered Indri indri in the Maromizaha Protected Area, Eastern Madagascar
A 24-Year Record of Female Reproductive Dynamics in Two Sympatric Mouse Lemur Species in Northwestern Madagascar
Seasonal reproduction is widespread among primates but the degree of reproductive synchrony and plasticity can vary, even between closely related species. This study compares the dynamics of female reproductive seasonality in two mouse lemur species, Microcebus murinus and M. ravelobensis, in Ankarafantsika National Park, Madagascar, across 24 years. We collected 4321 records of female reproductive state from 1033 individual females (319 M. murin…
High frequency/ultrasonic communication in a critically endangered nocturnal primate, Claire's mouse lemur ( Microcebus mamiratra )
The critically endangered Claire's mouse lemur, only found in the evergreen rain forest of the National Park Lokobe (LNP) and a few lowland evergreen rain forest fragments of northern Madagascar, was described recently. The present study provides the first quantified information on vocal acoustics of calls, sound associated behavioral context, acoustic niche, and vocal activity of this species. We recorded vocal and social behavior of six male-fe…
Averting Lemur Extinctions amid Madagascar's Political Crisis
Community-based management, ecotourism, and researchers' presence are proposed to prevent lemur extinctions.
Does nonnutritive tree gouging in a rainforest‐dwelling lemur convey resource ownership as does loud calling in a dry forest‐dwelling lemur
Nonhuman primates may defend crucial resources using acoustic or chemical signals. When essential resources are limited, ownership display for a resource may be enhanced. Defending resources may depend on population density and habitat characteristics. Using the Milne Edwards' sportive lemurs ( Lepilemur edwardsi ) and weasel sportive lemurs ( L. mustelinus ) as models, we tested whether two cryptic nocturnal lemur species differing in population…
Sleeping site ecology in a rain‐forest dwelling nocturnal lemur ( Lepilemur mustelinus ): Implications for sociality and conservation
Suitable sleeping sites as potentially restricted resources are suggested to shape sociality in primates. We investigated sleeping site ecology of a rain‐forest dwelling sportive lemur in eastern Madagascar for the first time. Using radiotelemetry, we characterized the type, quality and usage of sleeping sites as well as social sleeping habits of 11 focal individuals of the weasel sportive lemur ( Lepilemur mustelinus ) during the dry and the ons…
Geographic variation in loud calls of sportive lemurs ( Lepilemur ssp .) and their implications for conservation
Bioacoustical studies in nonhuman primates have shown that loud calls can be reliably used as a noninvasive diagnostic tool for discriminating cryptic taxa, for their monitoring in the field as well as for the reconstruction of their phylogeny. To date, it is unknown, whether loud calls can be used for these purposes in sportive lemurs, for which current genetic studies suggest the existence of at least 24 cryptic species. The aim of this study w…
Seasonality in Reproduction of Lepilemur edwardsi
Loud calling, spacing, and cohesiveness in a nocturnal primate, the Milne Edwards' sportive lemur ( Lepilemur edwardsi )
Dispersed pair‐living primates provide a unique model for illuminating the evolution of mechanisms regulating spacing and cohesiveness in permanently cohesive groups. We present for the first time data on the spatiotemporal distribution and loud‐calling behavior of the Milne Edwards' sportive lemur, known to forage solitarily during the night, but to form stable male‐female sleeping groups during the day. Data include radio‐tracking observations …
Social organization of the golden brown mouse lemur ( Microcebus ravelobensis )
Our study provides the first data on the social organization of the golden brown mouse lemur, a nocturnal primate discovered in northwestern Madagascar in 1994. The study was carried out in two 6‐month field periods during the dry season, covering time before and during the mating season. The spatial and temporal distributions of the sexes in the population were investigated by mark/recapture and radiotelemetry. Focal observations and the determi…

Pair‐specific usage of sleeping sites and their implications for social organization in a nocturnal Malagasy primate, the Milne Edwards' sportive lemur ( Lepilemur edwardsi )
Safe sleeping sites may be a limited resource crucial for survival. In order to investigate their potential significance for social organization in nocturnal primates, we analyzed the spatial distribution of daily sleeping sites, their characteristics, their usage, and sleeping group compositions in the nocturnal Milne Edwards' sportive lemur during a 6‐month field study in the dry deciduous forest of northwestern Madagascar. Sexes did not differ…
