Inclusion of empirical estimates of annual population fecundity
into stock assessment models may provide better estimates of reproductive potential than the current method.
The Effect of Exogenous 20E on Fecundity
and Longevity of Adults.
Furthermore, couple-level fecundity
was determined using only wives' reports, possibly underestimating husbands' infecundity and overestimating couples' unmet need.
estimates are only appropriate under the assumption that Alabama shad are isochronal spawners, producing one spawning batch in a season.
2013), and calculated the first known estimate of seasonal fecundity
for the Eastern Wood-Pewee in the Missouri Ozarks.
Couples should be aware that assisted reproduction technology (ART) cannot compensate for the age-related reduction in male and female fecundity
During the reproductive season, older and larger individuals produce more oocytes than younger and smaller spawners because fecundity
and spawning frequency are higher in larger females and, in general, their reproductive period is longer than the period of smaller spawners (Marshall et al.
Comparing both diets, they discovered that mother flies that grew as larvae on a protein diet had greater fecundity
and offspring possessing greater metabolic reserves than females grown as larvae on a diet that was predominantly sugar.
Our specific objectives were to characterize population structure, determine growth rate by sex, estimate and validate age and size at maturity using gonadal histology and otolith annuli measurements, and describe variations in batch fecundity
in relation to fish length and body mass.
Matrix elements indicate the stage-specific probabilities of transition and fecundity
They get both in this double SACD set of live recordings which instead focus on their felicitous orchestration, melodic fecundity
and romantic fervour.
Advanced understanding in the dynamics of fish fecundity
is of fundamental importance in fish and fisheries ecology and also has strong practical significance.
PC did not modify the growth, food intake, or fecundity
This resistance is mediated in parts by the host's production of antibodies against tick antigens (2), and ticks fed on resistant animals display delayed development, decreased fecundity
and increased mortality (3).
A chi-square test was used to analyze the estrous response, fecundity
, lambing and multiple birth rates among the groups at the 5% and 1% level of significance.
