'fertility values' is correct and usable in written English.
You can use it to refer to the measurement of the reproductive potential of a particular organism, such as when discussing the fertility rates of a population. For example, "The fertility values of the population saw a slight decrease in the second quarter of the year."
Soils on upland benches formed in limestones have soil fertility values that are comparable to fertile floodplain soils.
In each base pattern, the sum of the fertility values is one.
In this study, the wide ranges of values and skewed distributions indicated that more meaningful estimates of K status could be made if a population distribution of K fertility values was described using individual samples.
The standard cohort-component approach to population projection advances an initial population using a Leslie matrix, i.e., a projection matrix that has fertility values in its first row and survival probabilities on its subdiagonal (Preston et al. 2001, Chap. 6).
To facilitate the analytical model, the base age-specific fertility rates were adjusted to the desired NRR by a Sykes transformation (Sykes 1973), an approach that was also employed to adjust fertility values in the Coale and Trussell (1974) model fertility schedules.
However, on average, first litter latencies and other fertility values in the null mice were not significantly different from the controls.
If the base fertility value for the jth age group is f j, then the Sykes transformed fertility value, F j, is {F}_j={f}_j;exp left 5 rjright) (1 where the time interval is 5 years and r is the intrinsic annual rate of natural increase associated with the F j. Index j reflects the sequence of the 5-year age groups, with j = 1 for ages 0 4, j = 2 for ages 5 9, and so on.
Indeed, the lack of predictive fertility value of many proposed sperm quality parameters may be due to the fact that a mixed population of functional and non-functional spermatozoa is almost always considered.
The percent of hatching success (which was measured by dividing fertility by fecundity values) across the lineages ranges from 60 and 75% with the exception of Cytorace 13 (36%).
The Spanish data come from the survey of fertility and values conducted in 2006, and the Polish data are from the employment, family, and education survey conducted in 2006.
"Likely first domesticated in ancient Egypt, cats were revered for their fertility and valued for their ability to protect homes and granaries from vermin," the museum says.
