Social Pair-Bonding and Resource Defense in Wild Red-Bellied Lemurs (Eulemur rubriventer)

  title={Social Pair-Bonding and Resource Defense in Wild Red-Bellied Lemurs (Eulemur rubriventer)},
  author={Deborah J. Overdorff and Stacey R. Tecot},
Pair-bonding among nonhuman primates is rare and the possible selection pressures at work to maintain this type of social grouping have been discussed at great length (Kleiman, 1977; Wittenberger, 1980; Kinzey, 1987; Palombit, 1999; Fuentes, 1999, 2002; Chambers, 2002; Reichard, 2003; van Schaik and Kappeler, 2003). While the behavioral ecology of pair-bonded species has been relatively well studied across radiations, there are fewer studies that examine the nuances of social behavior between… 

Reproductive strategies and infant care in the malagasy primates

A number of studies in recent years have added to the understanding of this postnatal care strategy in lemurs, making it possible to include these species in broader taxonomic comparisons of primate reproductive strategies.

Ranging behavior and the potential for territoriality in pair‐living titi monkeys (Plecturocebus discolor)

The finding that red titi monkeys have a high potential for territoriality is consistent with several of the main hypotheses proposed to explain pair‐living in mammals.

Parentage complexity in socially monogamous lemurs (Eulemur rubriventer): Integrating genetic and observational data

Red‐bellied lemurs are generally reproductively monogamous, with only limited evidence that non‐nuclear families result from non‐monogamous reproduction, but similar to other pair‐living primates, red‐bellies appear to exhibit flexibility in their social organization and mating strategies.

Comfort Behavior of Black-and-White (Varecia variegata variegata) and Red (Varecia variegata rubra) Ruffed Lemurs (Primates, Lemuridae)

The results of this study showed that there are no significant differences in grooming between the black-and-white and red ruffed lemurs: in both subspecies, allogrooming is associated with a certain time of day to a lesser extent than autogroome.

The Island of Female Power? Intersexual Dominance Relationships in the Lemurs of Madagascar

The occurrence of female dominance in all lemur families and the interspecific variation in its extent indicate that it has evolved soon after lemurs colonized Madagascar – presumably in response to particular ecological challenges – and thatIt has since been reduced in magnitude independently in some taxa.

Female Dispersion Is Necessary, but Not Sufficient, for Pairbonded Monogamy in Mammals

It is shown that the females of monogamous genera do not have territories that are significantly larger, either absolutely or relatively, than those of polygynous genera and that the opportunity cost incurred by pairbonded males is typically 5–10 times the reproductive success they actually obtain by being obligately monogamous.

Signaling across the senses: a captive case study in pair-bonded red-bellied lemurs (Eulemur rubriventer) at the Duke Lemur Center, NC, USA

We provide a preliminary case study in red-bellied lemurs (Eulemur rubriventer) to illustrate a multimodal approach to understanding communication strategies within a species with obligate

Leading Ladies: Leadership of Group Movements in a Pair‐Living, Co‐Dominant, Monomorphic Primate Across Reproductive Stages and Fruit Availability Seasons

Sex differences in leadership in pairs of red‐bellied lemurs, Eulemur rubriventer, a monomorphic species with bisexual dispersal and no discernible hierarchy are investigated to determine whether higher energetic requirements by adult females lead to female leadership.

The evolution of social philopatry in female primates.

A theoretical model for the evolution of female social philopatry that supports the role of predator avoidance as a selective pressure for group-living in primates, but it also suggests that a second benefit of group- living, communal resource defense, might be required to trigger the Evolution of sizable groups.

Social Monogamy in Nonhuman Primates: Phylogeny, Phenotype, and Physiology

It is proposed that efforts to understand the biological underpinnings of complex human and animal sociosexual relationships will be well served by exploring individual phenotypic traits, as opposed to pursuing these questions with the assumption that monogamy is a unitary trait or a species-specific characteristic.



Pair living and mating strategies in the fat-tailed dwarf lemur (Cheirogaleus medius)

Paternity analyses, especially in bird species, have revealed that living with a permanent partner does not necessarily imply renunciation of additional matings with extra-pair mates, and that social monogamy masks a diverse range of genetic mating systems.

Mate guarding and the evolution of social monogamy in mammals

This chapter attempts to reconstruct the evolutionary routes by which social monogamy could have evolved, by considering the social and parental care systems that may have been exhibited by non-monogamous ancestors.

Pair-Bonding, Female Aggression and the Evolution of Lemur Societies

The internal structure of such lemur groups differs from the more extensive kin groups of catarrhines, which may relate to the lemurs’ level of social intelligence and to lemur female dominance over males.

An Ecological Model of Female-Bonded Primate Groups

A model is presented to account for the evolution of FB groups in terms of ecological pressures on female relationships and suggests that relationships in most FB groups are ultimately related to feeding competition.

Interspecific spacing between gibbons (Hylobates klossii) and langurs (Presbytis potenziani) on Siberut Island, Indonesia

This form of interspecific spatial organization between gibbons and langurs resembles certain predator‐prey spacing systems, where territorial boundaries between adjacent predators serve as sanctuaries for prey populations.

Dispersal, pair formation and social structure in gibbons (Hylobates lar)

Observations on reproduction, natal dispersal, pair formation, and group structure based on longitudinal observations of several white-handed gibbon groups spanning 18 years are at odds with the traditional view that gibbons live in nuclear family groups consisting of a pair of adults and their offspring.

Infanticide and the evolution of pair bonds in nonhuman primates

Protection from male infanticide has been offered as a potential benefit to females of bonds with males in a variety of primates, including mountain gorillas and gibbons, and this hypothesis is evaluated within a comparative framework that considers alternative costs and benefits of social relationships between the sexes.

Grooming Interactions Among the Chimpanzees of the Budongo Forest, Uganda: Tests of Five Explanatory Models

Patterns of allogrooming among the Sonso community of chimpanzees of the Budongo Forest, Uganda, were examined and found to closely resemble those at other study sites. Strong affiliative bonds among


The evidence supports the infanticide hypothesis, and it is speculated that infanticides avoidance is also responsible for the near-universal occurrence among primates of male-female bonds.
