Sexually transmitted diseases (STDs) are known to exist in wild and domesticated animals, but little is know about behavioural defences that animals use to reduce the risk of acquiring STDs. Using comparative data and a phylogeny of primates, I investigated whether behaviours hypothesized to reduce STD transmission are correlated with measures of STD risk involving mating promiscuity and life-h...

White-faced saki monkeys (Pithecia pithecia) lack most of the behavioral and physical traits typical of primate monogamy [Fuentes, 1999]. In order to determine if social bonds in this species reflect patterns displayed by pair-bonded groups or larger multimale-multifemale groups, we draw on 17 months of data collected on wild white-faced sakis at Brownsberg Nature Park, Suriname. We analyzed wi...

We establish a strong monogamy-of-entanglement property for subspace coset states, which are uniform superpositions of vectors in linear F2n to has been applied quantum one-time ...

In microtine and dwarf hamsters low levels of estrogen receptor alpha (ERα) in the bed nucleus of the stria terminalis (BST) and medial amygdala (MeA) play a critical role in the expression of social monogamy in males, which is characterized by high levels of affiliation and low levels of aggression. In contrast, monogamous Peromyscus males display high levels of aggression and affiliative beha...

family is the most fundamental social unit which can undergo a trauma when a new member joins it, leading to changes in its structure and function, thus inevitably altering the roles, duties and expectation of the members. therefore, conformity and nonconformity of family members and the subsequent effects on the family gains significance. other than the addition of a newborn baby and adoption,...

We study entanglement entropy inequalities in boundary conformal field theory (BCFT) by holographic correspondence. By carefully classifying all the configurations for different phases, we prove strong subadditiviy and monogamy of mutual information BCFT at both zero finite temperatures

Haldane’s rule of speciation states that sterility or inviability affects the heterogametic sex inter-species hybrids. Darwin’s corollary to implies there are asymmetric phenotypes in hybrids from reciprocal crosses. Studying F1 among closely related species malaria mosquitoes can assist researchers identifying genetic factors and molecular mechanisms speciation. To characterize sterile hybrid ...

Sexual behaviours are likely to have evolved under strong selective pressures since they are directly related to the breeding success of individuals. It is striking that the sexual behaviour of humans diVers so markedly from that of the two chimpanzee species with which we share more than 99% of our genome. The behaviour of the less closely related gorilla is more akin to that of many mammals—f...

Comparative studies of social insects and birds show that the evolution of cooperative and eusocial breeding systems has been confined to species where females mate completely or almost exclusively with a single male, indicating that high levels of average kinship between group members are necessary for the evolution of reproductive altruism. In this paper, we show that in mammals, the evolutio...
