For example, recent studies show that extra-pair copulation frequently occurs in monogamous birds in which a "social" father provides intensive care for its "social" offspring. [5] Furthermore, it was observed that newly formed pair bonds in biparental plovers were comparatively weaker than those in uniparental plovers.
Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases ...
Vasopressin is a hormone that induces a male Prairie vole to mate with one female, form a pair bond, and exhibit mate-guarding behavior (i.e. increase the degree of monogamous behavior). [4] The presence of vasopressin receptor 1A (V1aR) in the ventral forebrain is associated with pair bonding, which is necessary for monogamy. [15]
Examples of solitary primates: orangutans, galagos, lorises, some species of lemurs, some tarsiers. Lar gibbon (Hylobates lar) pair-bond. Pair-bonded systems, or pair-living primates, are small social units consisting of one adult male and one adult female, and their immature offspring. There are factors of time and space that define this type ...
The word monogamy derives from the Greek μονός, monos ("one"), and γάμος, gamos ("marriage"), referring to the functional social behaviour of pair-bonding. [1] The term can then be subsequently subclassified by context-dependent relational types. Generally, there are four intersecting definitions.
In both of these species, males and females are monogamous, pair-bonded, and exhibit bi-parental care for their offspring. [25] [42] [24] The social group in both these species consists of female and male parents along with their offspring. [43] [24] Males in these species serve as the primary caregivers and play a major role in infant survival ...
A monogamous relationship is one that is sexually and romantically closed to outsiders. In a monogamous relationship, the two people in it are pair-bonded to just one another, ...
As the alternative term "pair bonding" implies, this is usual in monogamy. In many polyandrous systems, the males and the female stay together to rear the young. In polygynous systems where the number of females paired with each male is low and the male will often stay with one female to help rear the young, while the other females rear their ...
