fecundity

[fə′kən·dəd·ē]
(biology)
The innate potential reproductive capacity of the individual organism, as denoted by its ability to form and separate from the body the mature germ cells.

fecundity

the physiological capacity to reproduce. This physical aspect must be distinguished from the social, economic and psychological influences which affect actual reproduction. Compare FERTILITY. See also DEMOGRAPHY, POPULATION, BIRTH RATE.

Age-specific fecundity (mx) was 0.132, 0.304 and 0.333 females per female per day at age of 26th day, 20th day and 15th day with age specific survival (lx) was 0.53, 0.46 and 0.24 days at 24 +- 0.5 AdegC, 27 +- 0.5 AdegC and 32 +- 4 AdegC, respectively.
A linear regression model was used to represent the relationship between fecundity and female size (TL) for Stage I and III.
The mean fecundity and mean relative fecundity were 14892.31 [+ or -] 2854.20 (3257.14-76377.36) and 49.82 [+ or -] 9.87 (6.27-21.85) respectively.
Fecundity was estimated by the number of developing embryos in the uteri and the number of developing oocytes in the ovaries.
When partners were modeled individually, no associations were observed between ln-transformed chemical concentrations and couple fecundity even after adjustment with the exception of the biomarker 4-HB (Table 3).
Additionally to the absolute fecundity, relative fecundity (RF) has also been calculated following Hardisty (1964):
Under hormonal protocol of fecundity trial seven goats (87.50%) out of eight goats showed induced estrus.
Daily observation were carried out to know the fecundity, the duration in the days of pre-oviposition, oviposition and post-oviposition periods, the egg hatching percentage, the larval development duration, pupal duration, survival and mortality on different artificial diets.
Understanding reproductive patterns, the size at maturity, the behavior of ovigerous females, fecundity, and egg/ larval quality all contribute to estimates of the turnover capacity of natural populations.
The fecundity ranged from 4365 to 65982, and mean fecundity was calculated 25349.
