    Alloparental Behavior
    (2017) Alba García de la Chica; Margaret Corley; Eduardo Fernández‐Duque
    Alloparental care is defined as care provided to offspring by individuals other than the parents of the recipient. The main types of care studied have been carrying, nursing, and food sharing, but alloparental care may also include indirect kinds of care such as grooming, playing, and territory defense. Alloparental care has its most extreme expression in the cooperative breeding systems present in callitrichid primates. Alloparental care may arise through a mother's tolerance of others caring for her offspring, or if other group members are motivated to provide care for her offspring. Several hypotheses have been proposed to explain why individuals who are not genetic parents to offspring sometimes care for them. Benefits to allocare givers may include the acquisition of maternal skills, the possibility of gaining a reproductive position or gaining increased access to potential mates, and improving one's own inclusive fitness.

    Owl Monkeys (Aotinae)
    (2016) Margaret Corley; Eduardo Fernández‐Duque
    The New World subfamily Aotinae consists of the genus Aotus , commonly called owl monkeys. The genus includes 11 species, which range over a variety of forest habitats, from Panama to northern Argentina. Owl monkeys are the only nocturnal anthropoids: all species display either nocturnal or cathemeral activity patterns, and their level of nocturnal activity is influenced by the amount of moonlight. All species are small‐bodied, arboreal, and lack prominent sexual dimorphism. Two aspects of owl monkey behavior make them relatively unique among primates: they are socially monogamous and exhibit intensive paternal care. All species live in small social groups of two to six individuals, which occupy a home range that includes a core area of exclusive use.
