Masculine Somatotype and Hirsuteness as Determinants of Sexual Attractiveness to Women
Study 5 showed that presence of trunk hair had a marked, positive effect upon women's ratings of attractiveness for both mesomorphic and endomorphic male figures, consistent with effects of sexual selection upon visual signals that advertise health, physical prowess, age, and underlying endocrine condition in the human male.

Sperm competition: Motility and the midpiece in primates
The results indicate that sexual selection by sperm competition has influenced the evolution of a specific component of male-gamete morphology, the volume of the sperm midpiece, in primate species with multiple-partner mating systems. Expand
Sexual Selection, Seminal Coagulation and Copulatory Plug Formation in Primates
Results indicate that sexual selection has played an important role in the evolution of seminal coagulation, and copulatory plug function, in primates. Expand
Human Physique and Sexual Attractiveness: Sexual Preferences of Men and Women in Bakossiland, Cameroon
These results are the first of their kind reported for a Central African community and provide a useful cross-cultural perspective to published accounts on sexual selection, human morphology and attractiveness in the U.S., Europe, and elsewhere. Expand
Sexual behavior, reproductive physiology and sperm competition in male mammals
Relationships between mating systems, relative testes sizes and sperm morphology, phallic morphology, circulating testosterone levels and sexual behavior in male mammals are analyzed and reviewed. Expand
Estimating mammalian species richness and occupancy in tropical forest canopies with arboreal camera traps
Large and medium-bodied rainforest canopy mammals are typically surveyed using line transects, but these are labour intensive and usually ignore nocturnal species. Camera traps have become theExpand
Sperm competition and the evolution of sperm midpiece volume in mammals
Results indicate that, within mammals, the evolution of sperm midpiece volume has been affected by selection pressures resulting from sperm competition, and the significance of these findings may relate to the density of mitochondria within the sperm midpieces. Expand
Why do flamingos stand on one leg?
It is suggested that the latency of flamingos to initiate forward locomotion following resting on one leg is significantly longer than following rest on two, discounting the possibility that unipedal resting reduces muscle fatigue or enhances predatory escape. Expand
Estimating daily walking distance of captive African elephants using an accelerometer.
This work uses an accelerometer, a pedometer that measures step count and activity level, to estimate walking distance in African elephants at the San Diego Zoo's Wild Animal Park and provides a linear regression equation that can be utilized by other institutions to estimate daily walking distance of elephants in their collection who are outfitted with accelerometers.

The Role of Lateralization in Feeding Behavior and Scratching Preference in Relation to Social Behavior in Captive Caribbean Flamingos (Phoenicopterus ruber)
Lateralization is defined as a behavior or mental process displayed by an animal in wh ich there is a distinctive side preference. Caribbean flamingos have been shown to display lateralization inExpand
