Causes and consequences of pair-bond disruption in socially monogamous species
… crustaceans to humans, form socially monogamous pair-bonds which are maintained during one or more consecutive breeding seasons. However, the ecological consequences of the disruption of monogamous pair-bond have rarely been addressed because it is difficult to estimate the rates and demographic …

Comparisons of Captive Gibbons’ (Hylobatidae) Intrapair Behaviors Indicative of the Pair Bond
I aimed to better understand captive gibbons’ pair bonds by studying behaviors that may indicate the relationship’s quality. I completed this research at The Gibbon Conservation Center (GCC) in Santa Clarita, California and observed four species: eastern hoolock (<em>Hoolock leuconedys</em>), Javan …

Pornography viewing as attachment trauma in pair-bond relationships-A theoretical model of mechanisms.
<p>Online sexual activities, including pornography use, have drastically increased in recent years. Many studies have examined the impact that pornography use can have on marriages and families. One of the key findings has been that pornography use can negatively impact trust in relationships. This …

General method for the development of models of electronic structure and bonding: covalent bonds, recoupled pair bonds and through-pair interactions
The concept of the chemical bond is essential to our understanding of molecular phenomena. G. N. Lewis laid the groundwork for our understanding of chemical bonds nearly a century ago in his classic 1916 paper in the Journal of the American Chemical Society, “The Atom and the Molecule.” This model …

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (taeniopygia Guttata)
… that stress can affect the propensity to form a pair bond. Data from humans and prairie voles, monogamous rodents, suggest that activation of the hypothalamic-pituitary-adrenal axis (HPA) in males increases attraction for females. Across species, females are understudied, but evidence from the …

Insights into the chemistry of sulfur-containing molecules
… dissertation, we utilize generalized valence bond (GVB) theory and the recoupled pair bonding model in order to understand the chemical bonding in a variety of sulfur-containing molecules. We use the resulting insights to rationalize experimental and computational results as well as to make …

Breeding behavior of captive emperor penguins (Aptenodytes forsteri)
… as a signal of sexual identity important in pair bond maintenance. Three head movements studied shared several functions including comfort behavior and reduction of intraspecific aggression. My observations confirmed that the display walk occurs in Emperors and is used by males to attract …

Flight Vocalizations and Displays of Adult Chimney Swifts (Chaetura Pelagica): Description and Function
… Chimney Swifts engaged in more interactive pair flights during the nest-building/egg-laying stage, when females are likely fertile, than any other stage, and significantly more than during the pre-building and nestling stages. This indicates importance of pair flights in courtship, pair …

Mate choice in the Polychaete nereis acuminata : the role of aggression and parental experience
… life cycle. A male and female form a monogamous pair bond, the female lays eggs and dies. The male then fertilises the egg and undertakes sole parental care until the eggs hatch and larvae leave the parental burrow; the male can then reproduce again. This body of work investigated aggression, …

Theoretical and computational investigations of the electron and spin correlation in chemical bonds, building a predictive bonding model with generalized valence bond theory
… is to understand the nature of chemical bonds. By understanding the underlying physical and chemical principles of chemical bonding in various molecules, chemists can make predictions about the structures, energetics, reactivities and other properties of chemical species. The …

The Effects Of Courtship And Pairing Behavior On The Nonapeptide And Noradrenergic Systems Of Adult Male And Female Zebra Finches
… is evidence that nonapeptides are important in pair bonding for both male and female zebra finches (Lowrey & Tomaszycki, 2014) and treatment with an OT antagonist results in an increased latency to pair in both sexes (Pederson & Tomaszycki, 2012). Thus, the role of nonapeptides in monogamous …

Theoretical studies of the bonding, energetics and spectra of sulfur and phosphorus halides, and reactivity of divalent sulfur compounds: impact of recoupled pair bonding
… (n=2-4)—are presented in this dissertation. The bonding in the ground and excited states of these species was analyzed using generalized valence bond theory. These (and other) studies have led to a model—the recoupled pair bond (RPB) model—that provided much insight into the electronic structure …

The sociality, ontogeny, and function of corvid post-conflict affiliation
… dependent on the presence of high quality social bonds. Affiliation should only occur with their mate because they are monogamous; the pair-bond being by far the highest quality relationship in the group. My results showed that the social species have third-party affiliation with their mate, while …

Social organisation, ecology and conservation of loris tardigradus tardigradus (lorisformes; primates)
… than intra-sexually. Lorises formed spatial pairs with coinciding home ranges and little overlap with neighbouring animals and had high indices of territoriality. Lorises were social 21.4% of the time, with neutral interactions being the most frequent, and direct negative interactions the …

Social defeat and oxytocin regulation of social avoidance and stress-related signaling proteins
… aggression towards unfamiliar conspecifics after pair bond formation. Once defeated, prairie voles exhibit social avoidance to unfamiliar individuals, an important indicator in the diagnosis of SAD in humans. Recently, we have documented that social defeat robustly affects the oxytocin system in …

The biology of the Cape Weaver Ploceus Capensis with special reference to its polygnous mating system

Finally, the special aspect of the study, the unusual polygynous mating system is investigated in detail. A possible evolutionary sequence for the development of polygyny …
