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 pertinent in Madagascar—one of the world’s poorest, least fo...

Terrestrial Behavior in Titi Monkeys (Callicebus, Cheracebus, and Plecturocebus): Potential Correlates, Patterns, and Differences between Genera
For arboreal primates, ground use may increase dispersal opportunities, tolerance to habitat change, access to ground-based resources, and resilience to human disturbances, and so has conservation implications...

Primate genoty** via high resolution melt analysis: rapid and reliable identification of color vision status in wild lemurs
Analyses of genetic polymorphisms can aid our understanding of intra- and interspecific variation in primate sociality, ecology, and behavior. Studies of primate opsin genes are prime examples of this, as sing...

Effects of Sex and Age on Heterothermy in Goodman’s Mouse Lemur (Microcebus lehilahytsara)
All habitats of Madagascar go through a dry season from April to September each year, resulting in a period of fruit scarcity lasting up to 6 months and creating selection pressure for adaptation to fluctuatio...

Diversity and Prevalence of Diarrhea-Associated Viruses in the Lemur Community and Associated Human Population of Ranomafana National Park, Madagascar
Diarrhea-associated viruses are common causes of morbidity in humans in develo** countries; however, they have seldom been studied in wild primates despite their pathogenic and zoonotic potential. This is of...

Communal nesting, kinship, and maternal success in a social primate
Communal nesting, where several mothers regularly pool and cooperatively rear offspring, is unusual in mammals. This type of crèching behavior is especially rare among primates, with the notable exceptions of ...

Conservation of Malagasy Prosimians: A View from the Great Red Island
Madagascar is a global biodiversity hotspot, with high levels of endemism coupled with a high degree of anthropogenic disturbance. Lemurs are important in maintaining the island’s ecosystems. We examine the pr...

Spatial Ecology of the Endangered Milne-Edwards’ Sifaka (Propithecus edwardsi): Do Logging and Season Affect Home Range and Daily Ranging Patterns?
Primates often live in human-altered habitats; Malagasy lemurs are no exception. It is important to understand if habitat alteration affects primates’ space use patterns across multiple spatial and temporal sc...

The Effects of Habitat Disturbance on Lemurs at Ranomafana National Park, Madagascar
The alarming rate of deforestation in Madagascar is driving some endemic primates to extinction. Surprisingly, anthropogenic habitat disturbance is not always deleterious. The effect of disturbance on lemur ab...

Object permanence in lemurs
Object permanence, the ability to mentally represent objects that have disappeared from view, should be advantageous to animals in their interaction with the natural world. The objective of this study was to e...

Predation on Lemurs in the Rainforest of Madagascar by Multiple Predator Species: Observations and Experiments
Predation by raptors, snakes, and carnivores is a constant risk for most wild primates (Cheney & Seyfarth, 1981; Anderson, 1986; Cheney & Wrangham, 1987; Janson & van Schaik, 1993; Cowlishaw, 1994; Isbell, 1994;

Morphological Variation in Populations of Eulemur albocollaris and E. fulvus rufus
Sexual dimorphism in body size and canine weaponry is commonly associated with high levels of male-male competition. When group living species do not rely heavily on male-male competition for access to females...

Effect of Season and Age on the Gonadosomatic Index of Milne-Edwards' Sifakas (Propithecus diadema edwardsi) in Ranomafana National Park, Madagascar
Aiming to explain individual variation in gonadosomatic index (testicular volume per body weight), we examined the relationship between gonadosomatic index (GI), age, and season in a wild, seasonally breeding ...
