Sexual Climax in Female Macaca mulatta
The view that female infra-human primates do not achieve orgasm is widespread [e.g. FORD and BEACH, 1952; MORRIS, 1967]. It has been assumed that this aspect of sexual behaviour is qualitatively different in man. While there has been much experimentation in the neurophysiology and endocrinology of sexual behaviour in infra-human primates over the past 30-40 years, the assumption that female mon...
متن کاملHorned Particles the Climax of Hawking Evaporation ?
We investigate the proposal by Callan, Giddings, Harvey and Strominger (CGHS) that two dimensional quantum fluctuations can eliminate the singularities and horizons formed by matter collapsing on the nonsingular extremal black hole of dilaton gravity. We argue that this scenario could in principle resolve all of the paradoxes connected with Hawking evaporation of black holes. However, we show t...
متن کاملTuring instability in pioneer/climax species interactions.
Systems of pioneer and climax species are used to model interactions of species whose reproductive capacity is sensitive to population density in their shared ecosystem. Intraspecies interaction coefficients can be adjusted so that spatially homogeneous solutions are stable to small perturbations. In a reaction-diffusion pioneer/climax model we will determine the critical value of the diffusion...
متن کاملEnergetics of metamorphic climax in the pickerel frog (Lithobates palustris).
Anuran metamorphosis, the transition from aquatic larvae to terrestrial juveniles, is accompanied by significant morphological, physiological, and behavioral changes. Timing of metamorphosis and final size, which can influence adult fitness, may depend on sufficient energy accumulated during the larval period to support metamorphosis. However, only two species of anurans have been examined for ...
متن کاملHoney bee (Hymenoptera: Apidae) pollination of rabbiteye blueberry Vaccinium ashei var. 'Climax' is pollinator density-dependent.
In a 2-yr field study, mature orchard plants of rabbiteye blueberry (Vaccinium ashei Reade variety 'Climax'), plus potted pollenizers ('Premier') were caged with varying densities of honey bees (0, 400, 800, 1,600, 3,200, 6,400, or 12,800 bees plus open plot) during the bloom interval. The rate of legitimate flower visits tended to increase as bee density increased within a range of 400-6,400 b...
