The phrase "adaptation of either" is correct and usable in written English.
It can be used when discussing the modification or adjustment of one of two options or elements.
Example: "The adaptation of either method could lead to improved results in the experiment."
Alternatives: "modification of either" or "adjustment of either".
We found that the two forms, Cantiga and nuba fit well together, with little need for adaptation of either form.
It is worth noting that this is not an adaptation of either of Abrams's movies, so it should escape the awfulness that afflicts most movie tie-in games.
As noted in the Methods section, we optimized the environmental conditions before proceeding to a therapeutic adaptation of either midazolam if the infant was assessed as "uncomfortable or agitated" or sufentanil if assessed as "hyperalgesic".
Host-parasite coevolution can lead to local adaptation of either parasite or host if there is specificity (GxG interactions) and asymmetric evolutionary potential between host and parasite.
Finally, as the system approaches steady state, there are no significant fitness gradients to drive adaptation of either bacteria or phage (i.e. dN dt → 0 and dV dt → 0 for all genotypes) and the genotype distributions are relatively constant over time.
However local adaptation of either bacteria or phages is not observed at these early stages of coevolution in this system despite favourable conditions for its occurrence [ 22], hence we do not use local adaptation as a measure of the evolutionary advantage of one species or another.
We identified and compared adaptations of either strain upon encountering an intracellular environment, and also contrasted the transcriptomes of the two strains while inside macrophages.
Therefore, adaptation to either of the modalities by themselves seems to play little role in producing the forward transition.
In none of the adaptations on either phage did lysis interval reach the predicted optimum.
Because the type III secretion system secretes both ExoS and ExoU, the adaptation to either one of these exoenzymes almost certainly involved interaction with different target eukaryotic organisms.
While there is compiling evidence of genotype-associated changes in herbivore performance and abundance [5],, only few studies have documented local adaptation of herbivores to either single plant genotypes within a species or to individual plants phenotypes [14], [15], [16], [17].
