“…Energy saving might also explain the relatively small home ranges of sportive lemurs-about 1 ha for L. edwardsi (see Albignac 1981;Warren and Crompton 1997) and L. ruficaudatus (Zinner et al 2003), and 0.18 ha for female and 0.33 ha for male L. leucopus (see Dröscher and Kappeler 2013). The much smaller grey mouse lemur (Microcebus murinus), with its broad diet, has similar home ranges of 0.7-1.6 ha for females and 2.8-4.8 ha for males in dry deciduous forest (Eberle and Kappeler 2004;Lahann 2008;Radespiel 2000). With a median size of 0.38 ha, the home ranges of the Sahamalaza sportive lemurs we observed were similar in size to those found for the white-footed sportive lemur (Dröscher and Kappeler 2013).…”

“…Mouse lemurs are small-bodied, nocturnal primates who live in a "dispersed" or "noyau" social system thought to be primitive for primates (Martin, 1972;Di Fiore and Rendall, 1994;Mü ller and Thalmann, 2000;Kappeler and van Schaik, 2002), where individuals typically forage independently in somewhat overlapping ranges, and the ranges used by adult males tend to overlap those of several females (Bearder, 1987). Among mouse lemurs, adult females typically share daytime nesting sites with several other females with whom their ranges overlap (Radespiel, 2000); during the nonmating season, males typically sleep apart from females, singly or in pairs (Martin, 1972;Radespiel, 2000), although mixed-sex sleeping associations are common during the mating season (Martin, 1972). Martin (1972Martin ( , 1973 hypothesized that groups of co-sleeping adult females might comprise matrilineally related individuals and that adult males in an area were immigrants and unrelated to resident females.…”

In the past several decades, the development of novel molecular techniques and the advent of noninvasive DNA sampling, coupled with the ease and speed with which molecular analyses can now be performed, have made it possible for primatologists to directly examine the fitness effects of individual behavior and to explore how variation in behavior and social systems influences primate population genetic structure. This review describes the theoretical connections between individual behavior and primate social systems on the one hand and population genetic structure on the other, discusses the kinds of molecular markers typically employed in genetic studies of primates, and summarizes what primatologists have learned from molecular studies over the past few decades about dispersal patterns, mating systems, reproductive strategies, and the influence of kinship on social behavior. Several important conclusions can be drawn from this overview. First, genetic data confirm that, in many species, male dominance rank and fitness are positively related, at least over the short term, though this relationship need not simply be a reflection of malemale contest competition over mates. More importantly, genetic research reveals the significance of female choice in determining male reproductive success, and documents the efficacy of alternative mating tactics among males. Second, genetic data suggest that the presumed importance of kinship in structuring primate social relationships needs to be evaluated further, at least for some taxa such as chimpanzees in which demographic factors may be more important than relatedness. I conclude this paper by offering several suggestions of additional ways in which molecular techniques might be employed in behavioral and ecological studies of primates (e.g., for conducting "molecular censuses" of unhabituated populations, for studying disease and host-parasite interactions, or for tracking seed fate in studies of seed dispersal) and by providing a brief introduction to the burgeoning field of nonhuman primate behavioral genetics.

“…We tried to radiocollar an equal number of males and females in the latter region, but could not track more than two females due to transmitter problems. We followed the activity of each animal using the radio-tracking equipment from Telonics Inc., Ariz. (TR-4 receiver with RA-14 K antenna) either by direct focal animal observation or by triangulation according to Radespiel (2000). Daytime sleeping places were localized in the morning or early afternoon.…”

“…Much information on the ecology, sociobiology and physiology, both in the field and under captive conditions, has been collected on this species (e.g. Martin 1972Martin , 1995Zimmermann and Lerch 1993;Ganzhorn and Schmid 1998;Fietz 1998;Radespiel et al 1998Radespiel et al , 2001aRadespiel et al , 2001bSchmid and Kappeler 1998;Zimmermann et al , 2000bSchmid 1999Schmid , 2001Radespiel 2000;Radespiel and Zimmermann 2001;Wrogemann and Glatston 2001). Chronobiological studies of gray mouse lemurs originating from western Madagascar showed that they exhibit photoperiodically driven seasonal rhythms in resting metabolic rate, body temperature, body mass, locomotor activity and reproduction under controlled captive conditions (e.g.…”

To investigate for the first time the relationship between contrasting patterns of seasonal changes of the environment and activity, body mass and reproduction for small nocturnal primates in nature, we compared a population of golden brown mouse lemur ( Microcebus ravelobensis) in a dry deciduous forest of northwestern Madagascar and of the brown mouse lemur ( Microcebus rufus) in an evergreen rain forest of eastern Madagascar. Both species live under similar photoperiodic conditions. Golden brown mouse lemurs (GBML) were active during the whole period (May to December) irrespective of changing environmental conditions. In contrast, a part of the population of brown mouse lemurs (BML) showed prolonged seasonal torpor, related to body mass during periods of short day length and low ambient temperatures. Differences between species might be due to differences in ambient temperature and food supply. Body weight and tail thickness (adipose tissue reserve) did not show prominent differences between short and long photoperiods in GBML, whereas both differ significantly in BML, suggesting species-specific differences in the photoperiodically driven control of metabolism. Both species showed a seasonal reproduction. The rate of growth and size of the testes were similar and preceded estrous onset in both species suggesting a photoperiodic control of reproduction in males. The estrous onset in females occurred earlier in GBML than in BML. Estrous females were observed over at least 4 months in the former, but in only 1 month in the latter species. Intraspecific variation of estrous onset in GBML may be explained by body mass. Interspecific variation of female reproduction indicates species-specific differences in the control of reproduction. Thus, environmentally related differences in annual rhythms between closely related small nocturnal lemurs emerged that allow them to cope with contrasting patterns of seasonal changes in their habitats.
