Parental care should evolve only if fitness benefits exceed fitness costs. In Cheirogaleus medius, a small nocturnal lemur of western Madagascar, we found the peculiar situation of considerable parental care by both sexes, combined with an extremely high rate of extra-pair young (EPY). In this paper, we try to elucidate the costs and benefits of parental care in C. medius, and we discuss hypotheses as to why males might actively participate in raising young, especially with regard to the high…

Life history traits and parental care in Lepilemur ruficaudatus
It is concluded that the necessity of direct infant care cannot explain the evolution and/or maintenance of pair‐living in Lepilemur ruficaudatus, a nocturnal folivorous lemur in Kirindy forest, western Madagascar.
No energetic benefits from sociality in tropical hibernation
It is concluded that sociality during hibernation is not necessarily driven by energetic demands and might even be energetically disadvantageous in tropical species (at least in larger groups), and other factors, like social coherence or ecological and behavioural constraints, may be of greater influence for the evolution of sociality under tropical conditions.
Determinants of Pair-Living in Red-Tailed Sportive Lemurs (Lepilemur ruficaudatus)
Results point towards the importance of female defence in explaining pair-living in L. ruficaudatus, a nocturnal primate from Madagascar, and discuss the spatial and temporal distribution of receptive females in relation to the female defence strategies of males and suggest possible costs that prevent male red-tailed sportive lemurs from defending more than one female.
Life history traits, maternal behavior and infant development of blue‐eyed black lemurs (Eulemur flavifrons)
The results suggest that overall recruitment of the critically endangered blue‐eyed black lemur is relatively slow, which has implications for the species' survival, particularly given their restricted and threatened habitat.
Living apart together: pair-living in red-tailed sportive lemurs (Lepilemur ruficaudatus)
The aim of this study was to characterize the spatial organization of red-tailed sportive lemurs (Lepilemur ruficaudatus) as a key aspect of their social organization and social system. Sportive
Spoilt for Choice: Selection of Hibernacula by Cheirogaleus medius
It is shown that large, well-insulated trees would allow a better controlled pattern of energy expenditure in hibernating animals rather than decreasing total amounts of energy expended.
Tree Hole Utilisation by the Hairy-Eared Dwarf Lemur (Allocebus trichotis) in Analamazaotra Special Reserve
Tree hole characteristics and use by the hairy-eared dwarf lemur (Allocebus trichotis) are described to determine habitat needs, potential functions of tree holes and sleeping group composition and to assess better the conservation needs of these species.
Paternal care in the striped mouse Rhabdomys pumilio: ontogeny and function
Mothers overcompensated in their maternal care behaviour in the absence of a male and the presence of a second care-giver, which correlated strongly with the greater levels of paternal care behaviour shown by their sons, and supports previous findings that fathers are important for offspring development and survival in this population.
Habitat Utilization of Three Sympatric Cheirogaleid Lemur Species in a Littoral Rain Forest of Southeastern Madagascar

The habitat utilization in 3 sympatric species of Cheirogaleidae in a littoral rain forest in southeastern Madagascar during 3 rainy seasons was compared to show significant interspecific differences in the choice of sleeping sites: smaller lemurs chose smaller trees and used more sleeping sites than larger lemur did.


Aspects of social life in the fat‐tailed dwarf lemur (Cheirogaleus medius): Inferences from body weights and trapping data
Field data on body weights of repeatedly trapped individuals combined with trapping results are presented to investigate the general biology and notably the social life of C. medius and show that adult males emerge from torpor earlier than females and offspring, even though food is still scarce.
High rates of extra-pair young in the pair-living fat-tailed dwarf lemur, Cheirogaleus medius
The reproduction strategy of C. medius in the tropical forest of western Madagascar was analyzed and a high rate of extra-pair paternity was detected, indicating that males may increase their reproductive success by EPCs without necessarily running the risk of cuckoldry.
Monogamy as a Rule Rather than Exception in Nocturnal Lemurs: the Case of the Fat-tailed Dwarf Lemur, Cheirogaleus medius
The results, together with the lack of sexual size dimorphism and relatively small testis size, suggest that the fat-tailed dwarf lemur lives in family groups with a monogamous mating system.
Feeding ecology of the hibernating primate Cheirogaleus medius: how does it get so fat?
A reduction in locomotor activity as well as a preference for fruit species with a high sugar content enable C. medius to deposit large quantities of fat in a few weeks, suggesting that this small nocturnal lemur hibernates during the dry season from the end of April until October.
Enhancement of reproductive success through mate choice in a social rock-wallaby, Petrogale assimilis (Macropodidae) as revealed by microsatellite markers
Results from a second colony of rock-wallabies in which the reproductive rate was accelerated were consistent with the hypothesis that females choose mates for their genetic quality, implying that by choosing better-quality fathers irrespective of social pairing, females are able to maximise their overall lifetime reproductive success, and presumably, those of their offspring.
Male-caused failure of female reproduction and its adaptive value in alpine marmots (Marmota marmota)
Reducing progesterone levels after the mating period and the lack of evidence for direct infanticide by new territorial males suggest a block of pregnancy as a likely explanation for reproductive failures in groups with male takeovers during gestation.
Male philopatry, extra-pack copulations and inbreeding avoidance in Ethiopian wolves (Canis simensis)
The possibility that extra-pair copulations may be widespread in canid societies and that the monogamy supposedly fundamental to the family may be more sociological than genetic is raised.
Intrasexual selection and testis size in strepsirhine primates
It was found that multi-male species had significantly larger testes than pair-Irving ones, but that they did not differ significantly from solitary species, which deviates from theoretical expectations, but may be the result of yet-unknown heterogeneity in mechanisms of male-male competition in both multi- male and solitary species.
