Ontogeny of Diet and Behavior of a Wild, Critically Endangered Lemur ( Indri indri )
The early developmental period plays a key role in primate behavioral outcomes. Understanding the behavioral ecology of infant indris ( Indri indri ) helps to identify resources needed during early developmental stages, the weaning process, and the role of mothers in developing infants' survival abilities. In this study, we investigated the behavioral and dietary development of wild Indri indri in Madagascar. We found that infants undergo signifi…
Dietary flexibility of the greater bamboo lemur ( Prolemur simus ), a specialized feeder, in eastern Madagascar
The degree of dietary flexibility in primates is species specific; some incorporate a wider array of resources than others. Extreme interannual weather variability in Madagascar results in seasonal resource scarcity which has been linked to specialized behaviors in lemurs. Prolemur simus , for example, has been considered an obligate specialist on large culm bamboo with >60% of its diet composed of woody bamboos requiring morphological and physio…
Variation in abundance and habitat use of the critically endangered Microcebus gerpi across its fragmented range
A link between the abundance of species and their degree of ecological specialization has previously been suggested within the primate order. Many species of lemurs were only recently described and even basic ecological data are not yet available for them. We investigated the habitat use, abundance, and habitat characteristics of the critically endangered Microcebus gerpi and evaluated potential impacts of vegetation structure and human disturban…
Feeding Ecology and Regurgitation–Reingestion Behavior of the Critically Endangered Indri indri in the Maromizaha Protected Area, Eastern Madagascar
Comparative Analysis of the Vocal Repertoires of the Indri (Indri indri) and the Diademed Sifaka (Propithecus diadema)
Strepsirrhine vocalisations are extraordinarily diverse and cross-species comparisons are needed to explore how this variability evolved. We contributed to the investigation of primate acoustic diversity by comparing the vocal repertoire of two sympatric lemur species, Propithecus diadema and Indri indri. These diurnal species belong to the same taxonomic family and have similar activity patterns but different social structures. These features ma…
Marking Versus Overmarking
In mammals, olfactory communication plays an essential role in territorial and mating dynamics. Scent depositions in various species, including lemurs, can be placed via marking or overmarking (marking over previous depositions). We focused on the role that marking and overmarking play in territorial defence and intrasexual competition. We investigated these aspects in diademed sifaka ( Propithecus diadema ) in the primary rainforest of Maromizah…
To tell a different story
Human–wildlife interactions are usually centred on the conflict between local populations and species that are perceived as problematic. To better understand the human dimension, social science approaches are increasingly incorporated to delimit opportunities for coexistence and species conservation. Here we explore local attitudes and beliefs about one of these ‘problematic’ species, the Endangered Aye‐aye Daubentonia madagascariensis , the larg…

Averting Lemur Extinctions amid Madagascar's Political Crisis
Community-based management, ecotourism, and researchers' presence are proposed to prevent lemur extinctions.

Gathering Local Knowledge in Madagascar Results in a Major Increase in the Known Range and Number of Sites for Critically Endangered Greater Bamboo Lemurs (Prolemur simus)
Conservation education in Madagascar
Few Malagasy children and adults are aware of the rare and unique fauna and flora indigenous to their island‐continent, including flagship lemur species. Even the Malagasy ancestral proverbs never mentioned lemurs, but these same proverbs talked about the now extinct hippopotamus. Madagascar's geography, history, and economic constraints contribute to severe biodiversity loss. Deforestation on Madagascar is reported to be over 100,000 ha/year, wi…
