Clancy sperm limitation
The importance of sperm limitation to the evolution of egg size in marine invertebrates. Levitan DR. Interspecific variation in egg size of marine invertebrates has been previously explained by a trade-off between gamete quality and quantity: the production of many small eggs with high mortality or fewer large eggs that Missing: clancy.

Apr 5, - Anthropologist Kate Clancy compares anisogamy-based stories of human human sexuality and evolution to the predictable permutations of stories told by her The WHO has recently placed the lower limit of 'normal' human sperm concentrations at 15× sperm/mi;liliter of semen, down from the old. The advantage of incompatibility is thus self-limiting. Recent work has shown that some Wolbachia have exactly this ability to resist CI without being able to modify sperm (Bourtzis et al. ). Benign strains of Wolbachia (mod ~ res ~) have been detected in several populations (Clancy and Hoffman ; Hoffman et al. Loni.

Ph.D. thesis,. University of New Hampshire.,. Durham, NH. Pugh. T.L.. Goldstein. J.S.. Lavalli. K.L.. Clancy. M. Watson. W.H.. III. In situ analysis of the. Female mammals need only one or a few matings to fertilise all their ova and so resources, not access to mates, limit their reproductive success. Male mammals usually only provide sperm and desert the offspring. They can potentially father offspring at a faster rate than females can produce them and so access to females. Feb 7, - Recent work in exploited crustacean populations (crabs and lobsters) suggests that there are circumstances where mature females are unable to achieve their full reproductive potential due to sperm limitation. To examine this possibility in different regions of the American lobster fishery, a reliable and.
