Previous studies have found that fecundity is a multigenic trait regulated, in part, by mitochondrial-nuclear (mit-n) genetic interactions. However, the identification of specific nuclear genetic loci or genes interacting with the mitochondrial genome ...

Genetic and environmental influences on the size-fecundity relationship in Aedes albopictus (Diptera: Culicidae): Impacts on population growth estimates? [PDF]
Population growth models are integral to ecological studies by providing estimates of population performance across space and time. Several models have been developed that estimate population growth through correlates of demographic traits, as measuring ...

"A Method for the Estimation of Fecundability." [PDF]
AbstractA new method for the estimation of the mean and variance of fecundability is described. The data input required for this procedure is the distribution of the interval from marriage to first birth, or from the resumption of the conception risk after contraception to the subsequent birth.

IMPACT survey: IMpaired fecundity in Physicians and Association with Clinical Time
Objective Studies suggest female physicians experience higher rates of infertility than the general population. The overall objective of this study was to determine the rate of impaired fecundity in a sample of female emergency physicians and compare it ...

Spawning frequency and batch fecundity were estimated for Brazilian flathead, Percophis brasiliensis, in Argentine coastal waters. Samples of this species were collected during the spawning period in November 1998 and 1999. Spawning frequency, determined

The cost of male aggression and polygyny in California sea lions (Zalophus californianus).
In polygynous mating systems, males often increase their fecundity via aggressive defense of mates and/or resources necessary for successful mating. Here we show that both male and female reproductive behavior during the breeding season (June-August ...
