The acquisition process of a novel behavior pattern in a group of ring-tailed lemurs (Lemur catta)
The process of acquisition and propagation of a novel behavior pattern in a group of 18Lemur catta was examined. Six of eight animals that acquired the new habit were infants or juveniles. Adult males did not tak...

A preliminary study of olfactory behavior of captiveLemur coronatus during the breeding season
The olfactory behavior of a captive population of crowned lemurs (Lemur coronatus)was studied during their annual breeding season in order to investigate its possible role in the fine-tun...

Resumes
Lors d’une étude de terrain réalisée pendant deux ans sur l’environnement et le comportement du aye-aye (Daubentonia madagascariensis) sur l’île de Nosy Mangabe, j’ai récolleté des données sur l’accouplement, la ...

Chapter
Sexual Selection and Lemur Social Systems
The lack of sexual size dimorphism among the lemurs of Madagascar affects agonistic relations between males and females, and therefore contributes to the most salient feature of lemur social systems: female do...

Chapter
Life History, Activity Period and Lemur Social Systems
Extant lemuriform and anthropoid primates differ dramatically in social behavior, grou** patterns, social structure, and sexual dimorphism In this paper, we analyze and contrast grou** and bonding patterns...

Life History Variation Among Nocturnal Prosimians
Principal life history traits determine the size of an organism at birth, how fast and how long it will grow, at what age and size it will mature, the number, size and sex of its offspring, as well as its repr...

Intrasexual selection in Mirza coquereli : evidence for scramble competition polygyny in a solitary primate
The primates of Madagascar (Lemuriformes) deviate from fundamental predictions of sexual selection theory in that polygynous species lack sexual dimorphism, have even adult sex ratios and often live in female...

To whom it may concern: the transmission and function of chemical signals in Lemur catta
The goals of this study were to investigate the transmission and possible functions of chemical signals in intragroup communication among ring-tailed lemurs, Lemur catta. In particular, I examined the effects of...

Fluctuating sexual dimorphism and differential hibernation by sex in a primate, the gray mouse lemur (Microcebus murinus)
The aim of this study was to investigate reproductive strategies and their consequences in gray mouse lemurs (Microcebus murinus), small solitary nocturnal primates endemic to Madagascar. Previous reports of sexu...

Chapter
Cathemeral Activity of Red-Fronted Brown Lemurs (Eulemur Fulvus Rufus) in the Kirindy Forest/CFPF
Cathemeral activity, which is defined by sequences of activity bouts and resting phases throughout the 24 hour cycle, is rare among primates but common among group-living lemurs. The proximate and ultimate cau...

Mouse lemurs in space and time: a test of the socioecological model
Socioecological theory predicts that the distribution of fertile females in space and time is the major determinant of male spacing behavior and mating strategies. Using a small nocturnal Malagasy primate, th...

Anti-predator behavior of group-living Malagasy primates: mixed evidence for a referential alarm call system
Many mammals warn conspecifics with alarm calls about detected predators. These alarm calls are either functionally referential, urgency based, or they can have multiple functions, including predator deterren...

Article
The genetic population structure of the gray mouse lemur (Microcebus murinus), a basal primate from Madagascar
The genetic structure of a population is closely connected to fundamental evolutionary processes and aspects of social behavior. Information on genetic structure is therefore instrumental for the interpretati...

Article
Evolution of Primate Social Systems
We review evolutionary processes and mechanisms that gave rise to the diversity of primate social systems. We define social organization, social structure and mating system as distinct components of a social s...

Article
Seasonal variation and social correlates of androgen excretion in male redfronted lemurs (Eulemur fulvus rufus)
The aim of this study was to examine effects of seasonal and social factors on male androgen excretion in a seasonally breeding primate living in multimale-multifemale groups. By combining detailed behavioura...

Article
Social Organization of Lepilemur ruficaudatus
We characterize the spatial organization of red-tailed sportive lemurs (Lepilemur ruficaudatus) as a key aspect of their social organization and social system. Sportive lemurs are small (<1000 g), nocturnal and f...

Article
On the move around the clock: correlates and determinants of cathemeral activity in wild redfronted lemurs (Eulemur fulvus rufus)
Whether animals are active at night or during the day has profound consequences for many aspects of their behavioral ecology. Because of ecological and physiological trade-offs, most animals, including primate...

Article
Small testes size despite high extra-pair paternity in the pair-living nocturnal primate Phaner furcifer
Sperm competition will be the inevitable consequence of polyandrous mating behavior if two or more males inseminate a single female. It has been demonstrated for a wide variety of animals that males adapt to t...

Effects of Seasonal Water Scarcity on the Ranging Behavior of Eulemur fulvus rufus
The climate of western Madagascar is characterized by a long (8–9 mo) dry season during which small rivers run dry, so that most animals are dependent on access to a few permanent water holes. We studied the e...
