Reproductive skew in female common marmosets: what can proximate mechanisms tell us about ultimate causes?

Journal Article Proceedings. Biological sciences · February 2009 Common marmosets are cooperatively breeding monkeys that exhibit high reproductive skew: most subordinate females fail to reproduce, while others attempt to breed but produce very few surviving infants. An extensive dataset on the mechanisms limiting repro ... Full text Cite

Reproductive skew in female common marmosets: Contributionsof infanticide and subordinate self-restraint

Chapter · January 1, 2009 The common marmoset (Callithrix jacchus) is a cooperatively breeding monkey that exhibits high reproductive skew among females. At the proximate level, this high skew is maintained, for the most part, by reproductive selfrestraint in subordinates, involvin ... Full text Cite

Maintenance of female dominance in blue-eyed black lemurs (Eulemur macaco flavifrons) and gray bamboo lemurs (Hapalemur griseus griseus) under semi-free-ranging and captive conditions.

Journal Article Zoo biology · September 2007 Several species of Malagasy prosimians are characterized by female dominance, an unusual trait among mammals. We compare the extent to which female dominance is displayed and the mechanisms that are used to maintain dominance in the frugivorous blue-eyed b ... Full text Cite

Infanticide by female mammals: implications for the evolution of social systems

Chapter · November 2, 2000 Infanticide by males and its implications Male primates, carnivores and rodents sometimes kill infants that they did not sire. Infanticide by males is a relatively common phenomenon in these groups, but tends to be rare in any given species. ... Cite
