The phrase 'evenness between' is correct and usable in written English.
You can use this phrase to refer to a state of fairness or balance between two or more items. For example, you might say, "The evenness between the two sides was essential to the success of the negotiations."
For example, we found large differences in functional evenness between the total catch and reported catch for the Desventuradas Islands of Chile.
The rototilling and stubble-breaking performances, the seeding stability, uniformity and evenness between rows of the planter and the performance of the fertilizing unit of the machine were measured.
In general, the difference in functional dispersion estimates between the total catch and different groupings was lower than for functional evenness, and many EEZs that showed large differences in functional evenness between the total catch and specific groupings did not show large differences in functional dispersion (EEZs with paler shading in Fig. 7 than in Fig. 6).
The variations in the diversity, species richness, and evenness between two cropping systems are discussed in this paper.
We observed a significant difference in functional diversity and evenness between biofilm cells taken from each polymer (Figure 7A,B).
Similar patterns were observed after four years of herbivore exclusion (Figure 1d); the difference in plant community evenness between the areas used by livestock and native herbivores had decreased (Table 2).
We developed a new integrative indicator HT* that takes account of varietal richness, spatial evenness, between-variety genetic diversity, and within-variety genetic diversity.
In studied farmlands, the community structure of soil algae varied significantly from type to type, with Shannon diversity index ranging between 1.89 and 4.63, evenness index between 0.54 and 0.93, and Simpson's index between 0.44 and 0.91 (Table 5).
Many EEZs showed little difference in functional evenness estimates between the total catch and specific groupings within the catch (yellow shading in Fig. 6).
Coral colony size distributions were less dynamic, species richness did not significantly change, and evenness increased between 2003 and 2007 (paired t-test, P<0.01).
The average number of bands, H' and evenness (E) between the two groups was listed in Table 2.
