Synthesis, Structure, and Luminescent Property of the Templated Borate [C9H14N]·[B5O6(OH)4]

The templated borate, [C9H14N]·[B5O6(OH)4], was synthesized under hydrothermal conditions. Single crystal X-ray diffraction techonology reveals that it crystallizes in the triclinic system, space

Paternal occupation and offspring sex ratio

Between 1961 and 1997, there were 15 reports of unusual secondary sex ratios related to paternal occupation. Thirteen of these documented a statistically significant predominance of female births

Information content of sexual swellings and fecal steroids in sooty mangabeys (Cercocebus torquatus atys)

The accuracy and precision of sexual swellings and fecal steroids as measures of ovarian function and the periovulatory period were compared in 4 sexually mature, individually housed, sooty mangabey females to illustrate the utility of fecal steroid analysis for further evaluation of the signal value of sexual skin and its role in mating interactions.



Dominance and fertility among female primates

Observations that dominant individuals sometimes feed on better quality foods, expend less energy or time in obtaining food, or are interrupted less often when feeding, indicate that the effects of competition on fertility could be working through nutrition.

Social mechanisms of population regulation in a captive group of bonnet macaques (Macaca radiata)

Environmental factors, such as availability of food and vulnerability to predation, were unlikely to constrain population growth in captivity, and data suggest that other mechanisms may have affected demographic processes in this captive group.

Behaviourally mediated suppression of reproduction in female primates

This paper considers why, how and at what physiological level dominant females suppress reproduction in female subordinates, and concentrates on the specific physiological mechanisms that impose inhibition of ovulation in subordinate female marmoset monkeys.

Reproductive constraints on aggressive competition in female baboons

It is reported here that high-ranking female baboons at Gombe National Park, Tanzania, enjoy shorter interbirth intervals, improved infant survival, and accelerated maturation of their daughters, but these advantages are countered by a significantly higher probability of miscarriage, and a proportion of high- ranking females suffer from reduced fertility.

Reproduction in wild female olive baboons

Evaluating several factors that influence female reproduction in a large troop of wild olive baboons found that dominance rank did not influence sex ratio at birth, infant survival in the first 2 years, or adult female mortality.
