The Neurochemistry of Pair Bonding
Current Directions in Psychological Science, 2003The formation and maintenance of social attachments are fundamental to human biology. Because deficits in the ability to form such attachments are associated with a variety of psychological disorders, an understanding of the neural basis of social attachment may provide insights into the causes of such disorders.

The three North American ptarmigan species are monogamous, whereas the other six North American grouse species are polygynous. In the Arctic there are few nest predators, which means ptarmigan should be prepared to nest nearer each other than polygynous grouse that lose more nests to predators.

Facial expressions and pair bonds in hylobatids
American Journal of Physical Anthropology, 2018AbstractObjectivesFacial expressions are an important component of primate communication that functions to transmit social information and modulate intentions and motivations. Chimpanzees and macaques, for example, produce a variety of facial expressions when communicating with conspecifics.

AbstractOnly a handful of primate species exhibit the social relationship of pair‐bonding. Efficient communication is critical for behavioral coordination within pair‐bonds to maintain proximity and respond appropriately to extra‐pair individuals, and possibly coordinate infant care.

Pair bonding is an exclusive mating relationship associating the memory of a mate with the potential successful completion of a breeding cycle. In evolutionary biology, pair bonding has been studied as a mating strategy and this biological phenomenon has been associated with survival related reproductive behaviors, however, behaviors that function in ...

Human male pair bonding and testosterone
Human Nature, 2004Previous research in North America has supported the view that male involvement in committed, romantic relationships is associated with lower testosterone (T) levels. Here, we test the prediction that undergraduate men involved in committed, romantic relationships (paired) will have lower T levels than men not involved in such relationships (unpaired).

Halogen Bonding in DNA Base Pairs
Journal of the American Chemical Society, 2012Halogen bonding (R-X···Y) is a qualitative analogue of hydrogen bonding that may prove useful in the rational design of artificial proteins and nucleotides. We explore halogen-bonded DNA base pairs containing modified guanine, cytosine, adenine and thymine nucleosides. The structures and stabilities of the halogenated systems are compared to the normal

Monogamous pair bonding in genetic algorithm
2015 IEEE Congress on Evolutionary Computation (CEC), 2015A new variant of the Genetic Algorithm (GA) inspired by monogamy mating system is put forward. The Monogamous Pairs Genetic Algorithm (MopGA) incorporates two important operations: pair bonding and infidelity at a small probability. With pair bonding, parents continue to mate at each iteration until their bond expires.

Pair Formation and Pair Bond in Captive Rooks
Bird Study, 1976Although the author's Rooks are captive birds, his close observation of their ‘personal’ relationships within the ‘colony’ throws interesting light on facets of pair-formation and behaviour during the breeding cycle.

In a previous paper in this series, we discussed the formation of recoupled pair bonds in the a4Σ- states of CF and SF in which the recoupling process was essentially complete at the equilibrium geometry of the molecule. In this paper, we examine the a4Σ- state of oxygen monofluoride (OF), which could also have a recoupled pair bond.
