Aggressive Behavior of Black-and-White Ruffed (Varecia variegata variegata) and Red Ruffed (Varecia variegata rubra) Lemurs (Primates, Lemuridae)
AbstractAggressive behavior of 155 individuals of black-and-white ruffed lemurs ( Varecia variegata variegata (Kerr 1792)) and red ruffed lemurs ( Vare...

Impact of model assumptions on demographic inferences: the case study of two sympatric mouse lemurs in northwestern Madagascar
BackgroundQuaternary climate fluctuations have been acknowledged as major drivers of the geographical distribution of the extraordinary biodiversity...

Arboreal Lemur Terrestriality is Influenced by When and Where Predators are Present
It is thought arboreal species avoid foraging on the ground due to perceived predation risk, making the study of when and where arboreal species use...

Telomere dynamics during hibernation in a tropical primate
Hibernation is a widespread metabolic strategy among mammals for surviving periods of food scarcity. During hibernation, animals naturally alternate...

Mid-Cenozoic climate change, extinction, and faunal turnover in Madagascar, and their bearing on the evolution of lemurs
BackgroundWas there a mid-Cenozoic vertebrate extinction and recovery event in Madagascar and, if so, what are its implications for the evolution of...

Seasonal changes in dietary compositions of the Malayan flying lemur (Galeopterus variegatus) with reference to food availability
Flying lemurs are able to glide using a thin membrane of skin (patagium) connected to their limbs, body, and part of tails. The Malayan flying lemur (

Genetic Model Organisms
Model organisms are non-human species used for studying biological processes in laboratories. They are selected based on advantageous properties such...

Photorefractoriness and Recovery of Photosensitivity in a Seasonal Nonhuman Primate (Microcebus murinus)
Primates show a range of reproductive seasonality patterns, from year-round to strictly seasonal breeding. Seasonality depends on several factors,...

A Coupled Humanitarian and Biodiversity Crisis in Western Madagascar
The unsustainable hunting and consumption of primates destabilizes both wildlife populations and the humans who depend upon them. This is especially...

An invasive species spread by threatened diurnal lemurs impacts rainforest structure in Madagascar
Invasive species are a major threat to biodiversity and ecosystem function. Thus, understanding their spread and ecological impacts is critical for...

Measuring the Impact of Forest Edges on the Highly Arboreal Sahamalaza Sportive Lemur, Lepilemur Sahamalaza, in North-Western Madagascar
The progressive fragmentation of forest habitat is causing an increase in edge areas that may differ structurally and in quality from forest...

Bioacoustic characterization of the black-and-white ruffed lemur (Varecia variegata) vocal repertoire
Ruffed lemurs ( Varecia spp.) exhibit a unique suite of behavioral traits compared to other lemur species, which includes their fluid fission–fusion...

Lemur Gut Microeukaryotic Community Variation Is Not Associated with Host Phylogeny, Diet, or Habitat
Identifying the major forces driving variation in gut microbiomes enhances our understanding of how and why symbioses between hosts and microbes...

Water Availability Impacts Habitat Use by Red-Fronted Lemurs (Eulemur rufifrons): An Experimental and Observational Study
With the predicted increase in extreme weather events as a result of global climate change, animals living in dry or seasonally dry habitats are...

Drivers and consequences of female reproductive competition in an egalitarian, sexually monomorphic primate
AbstractEven after the 150th anniversary of sexual selection theory, the drivers and mechanisms of female sexual selection remain poorly studied. To...

Gut Microbial Diversity and Ecological Specialization in Four Sympatric Lemur Species Under Lean Conditions
The gut microbiome is gaining recognition for its role in primate nutrition, but we stand to benefit from microbiome comparisons across diverse hosts...

Biotic and abiotic dispersal of a large-seeded keystone genus in Madagascar
In tropical forests, most plant species rely on frugivorous animals for seed dispersal services. Such mutualisms are imperiled by defaunation, which...

Seasonal Differences in the Encounter Rate of the Fat-Tailed Dwarf Lemur (Cheirogaleus medius) in the Transitional Forests of Northwest Madagascar: Implications for Reliable Population Density Assessment
Primate encounter rates often vary throughout the year due to seasonal differences in activity, ecology, and behaviour. One notably extreme behaviour...

Intraspecific macroscopic digestive anatomy of ring-tailed lemurs (Lemur catta), including a comparison of frozen and formalin-stored specimens
Digestive tract measurements are often considered species specific, but little information exists on the degree to which they change during ontogeny...

Portrayals of wild primates in documentary films: reason for concern?
Documentaries are the primary means by which many people observe the behavior of wild primates. By influencing layperson perceptions of wild...
