Validity of an estimator of reproductive success
American Journal of Primatology, 1998Lifetime reproductive success is a major component of individual fitness and a central dependent variable for the study of natural selection. For long-lived animals, such as apes or baboons, assessment of lifetime reproductive success requires observations of identified individuals in continuous, long-term studies from which it is difficult and often ...

Criteria of reproductive success
American Journal of Primatology, 1997To determine reproductive success, it is necessary for the researcher to specify a criterion of success, such as the number of a parent's offspring living to the age of reproduction. A measurement model, which includes the researcher's choice of criterion, has been proposed to estimate the lifetime reproductive success (R) of long-lived animals from ...

Reproductive success: Which meaning?
American Journal of Human Biology, 2003AbstractThe theory of kin selection (the part played by behavior in the changes of mean inclusive fitness) induced many human sociobiologists to think that since behavior was involved in the increase in fitness, this last entity could apply to the individual.

Reproductive success for social Hymenoptera
Theoretical Population Biology, 1978Abstract An organism's “reproductive success” is a quantity designed to measure the extent to which genes descended from that organism will be represented in distant future generations. A mathematical justification is given for the formulation of reproductive success used in a recent study of the evolution of sex ratio in eusocial Hymenopteran ...

INFANTICIDE IN THE EVOLUTION OF REPRODUCTIVE SYNCHRONY: EFFECTS ON REPRODUCTIVE SUCCESS
Evolution, 2008Synchronous breeding in animals and plants has stimulated both a theoretical and empirical examination of the possible benefits of active synchronization. The selective pressures of predation and infanticide are the strongest candidates proposed to explain the evolution of reproductive synchrony. Alternatively, breeding asynchronously with conspecifics

Autoantibodies, alloantibodies and reproductive success
Current Opinion in Immunology, 1990It is only since the recognition of rhesus haemolytic disease that the importance of the maternal immune response to fetal antigens has been widely appreciated. The discovety that rhesus isoimmunization can be prevented by an antibody directed against the rhesus D antigen on fetal red cells was an extremely important step forward, as it showed that the

The effect of habitat supplies on the survivorship and reproductive success of plants has been fully understood (Harper and Ogden 1970, Harper 1977, Silvertown 1983). It has also been found many times that the proportions of species with different reproduction strategies vary with the succession phases (Horn 1974, Newell and Tramer 1978, Noble and ...
