Primate Mating Systems Part 1: Monogamy

  • Monogamous is exclusive mating. Males and females will only mate with each other (Kleiman, 1977). Kleiman (1977) suggests four characteristics in define monogamy
  1. Close proximity of an adult heterosexual pair both during and outside reproduction periods.
  2. Mating preferences.
  3. Absence of other unrelated adult within the home range, nest or territory of the monogamous pair.
  4. Breeding by one adult pair in a family group
  • Kleiman (1977) splits monogamy into two different types: high paternal investment and low paternal investment. Kleiman (1977) suggest this differing level of investment likely is due to environmental factors. Low paternal investment may occur due to the over dispersion of adults (Kleiman 1977).
  • Certain characteristics occur within monogamy that differs from non-monogamous mating systems.
    • Sexual dimorphism is reduced
    • Paternal investment in high
    • Juveniles exhibit delayed sexual maturation when they remain within their family group
    • Juveniles will contribute to rearing their siblings (Kleiman, 1977).
    • A new pair is more likely to interact frequently than a well-established pair.
  • Kleiman and Eisenberg (1973) a general pattern of monogamy is greater reproductive burden in which a solitary mother would have to great a burden to care for her offspring.
  • Wilson (1975) suggested three ecological conditions to explain monogamy.
  1. Scarce or valuable resource that need two adults to defend it.
  2. Physical environment is harsh and thus need two adults to survive within it.
  3. Early breeding
  • Wittenberger and Tilson (1980) summarize five hypotheses of requirements that lead to monogamy
  1. Male parental care is essential to female success
  2. Pairing must with an unmated male must be better than pairing with an already paired male
  3. Majority of males should only be able to successfully mate with females by defending an exclusive territory.
  4. Aggression of mating females prevents males from acquiring more/other mates
  5. Males are less successful with two mates in comparison to one.

    • Siamang (Chivers, 1972)

  • Extra pair copulation (ECP) is a widely discussed topic within monogamy. Since several monogamous species participate in extra pair copulation. This involves one of the members of the pair leaving the other member to copulate with another member of their species (Trivers, 1972).
  • Several species of primates participate in extra pair copulation.
    • Indri (Bonadonna et al. 2014)
    • Several species of gibbons (Palombit, 1994b)
    • Marmosets (Digby, 1999)
    • Dwarf lemurs (Fietz et al. 2000)
    • Sifakas (Lawler, 2007)
    • Forked mark lemurs (Shülke et al. 2004)
    • Red bellied titis (Mason, 1966)
  • In order for the ECP to be beneficial it must first outweigh any costs occuring from pursuing more mating oppurtunities (Bonadonna et al. 2014) and loss of parental gains (Westneat et al. 1990).
  • Females will often pariticipate in extra pair copulation in order to gain genes that increase the heterozygosity of their offspring, get fitter genes, or gain insurance of fertilization (Westneat et al. 1990).
