The phrase "a function of abundance" is correct and usable in written English.
It can be used in contexts where you are discussing how one variable or outcome is influenced by the level of abundance of another variable.
Example: "The growth rate of the species is a function of abundance, meaning that as food sources increase, so does the population size."
Alternatives: "dependent on abundance" or "related to abundance".
Figure 18 Enhancement of total sediment carbon oxidation due to increased microbial degradation in the presence of irrigated burrows (E1 = Ciox/Cdox) and reworking (Er = Crox/Cdox) as a function of abundance of Nereis diversicolor and Arenicola marina.
Relative activity-density is a function of abundance and movement and hence should be interpreted with caution but is a valuable parameter to estimate from data on presence or absence of a species at a site.
Nonlinearities in the average bias curve indicate that the bias is a function of abundance.
We detected variation in δN at different stream reaches, most likely as a function of abundance and species of spawning salmon.
While scatter plots and correlations are useful, it is generally easier to visually detect and assess magnitude of disagreement and whether the variability in disagreement is a function of abundance in an MVA plot.
However, although the absolute disagreement is a function of abundance, the moving average smoother indicates that average disagreement or bias between technical replicates is consistently linear (rather than nonlinear) over the abundance range.
The constraint w nn = 0 prevents gene n from influencing itself at the same instant so its abundance is a function of the abundances of the remaining N - 1 genes in the same profile.
The transmission function is wavelength dependent and a function of the abundance of ozone and molecular oxygen in the model.
The Mantel test was used to test for correlation between intersample distances calculated as a function of REE abundance and XRD spectra correlations.
Plag#10 and Plag#14 have higher 36Arm compared to that of other fragments; however, the 40Ar/39Ar ages do not appear to be a function of the abundance of measured 36Ar (Fig. 6).
The overall RNAi efficiency in an experiment is also a function of the abundance and the stability of both the target mRNA and the encoded protein, and the precise region of the mRNA targeted for scission.
