Endocrine changes in male stumptailed macaques (Macaca arctoides) as a response to odor stimulation with vaginal secretions
In mammalian species, social chemosignals are important in modulating endocrine reproductive functions. In nonhuman primates, previous studies have described a high frequency of mounting behavior byExpand

Enforced water drinking induces changes in burying behavior and social interaction test in rats
The effect of water deprivation and water intake on experimental anxiety in rats was tested using burying behavior (BB) and social interaction (SI) anxiety paradigms. Two groups of animals wereExpand

The menstrual cycle of the spider monkey (Ateles geoffroyi)
The ovarian cycles of four adult female spider monkeys (Ateles geoffroyi) were followed daily throughout 30 days by means of vaginal swabs and blood samplings. Cytological analyses of the vaginalExpand

Comparison of the effects of Percoll and PureSperm® on the common marmoset (Callithrix jacchus) semen
Abstract:  Density gradient centrifugation is a widely used technique for the separation of motile from non‐motile sperm, for the removal of contaminating agents such as bacteria and viruses, and forExpand

Sperm quality differences between the rainy and dry seasons in captive black‐handed spider monkeys (Ateles geoffroyi)
The present work provides an assessment of sperm measures (concentration, motility, viability, etc.) of three black‐handed spider monkeys (Ateles geoffroyi) during the rainy and dry seasons in MexicoExpand

Interfering in affiliations: sabotaging by stumptailed macaques, Macaca arctoides
Stumptailed macaques use a number of acts to interrupt and disrupt affiliative interactions involving other group members. In this paper I describe such interference and raise the hypothesis that itExpand

Innovative social behavior in chimpanzees (Pan troglodytes)
We present evidence of agonistic buffering in captive chimpanzees, recorded from 1993 until 2005, mainly from ad libitum sampling in over 2000 hr of observation. A total of 33 agonistic bufferingExpand

Seasonal variations of fecal progesterone and 17beta-estradiol in captive female black-handed spider monkeys (Ateles geoffroyi).
A number of studies in free-ranging and captive spider monkeys (Ateles spp.) have shown that this genus is able to reproduce throughout the entire year. Nonetheless, it is still controversial whetherExpand

The seminal coagulum favours passage of fast-moving sperm into the uterus in the black-handed spider monkey.
In addition to gametes, mammalian internal fertilisation has required the evolution of assorted anatomical, physiological and biochemical devices to deal with intra- and inter-sexual conflict such asExpand
