"geographic differentiation" is a correct and usable phrase in written English.
You could use this phrase to describe the variance in a certain phenomenon based on geographic location. For example, "In this study, we observed geographic differentiation in population structure."
These observations are consistent with fine-scale geographic differentiation as well as population growth.
Multi-regional input-output analysis (MRIO) allows for including trade between different regions as well as geographic differentiation of economic and environmental aspects.
Although little or no geographic differentiation was observed, there was enough population genetic structure across the accessions to divide them into six groups, one for indica and five for the japonica accessions (Supplementary Table 3).
However, putting the validity of using DNA fragments for indica japonica differentiation aside, does this pre-domestication divergence of the A-genome wild rice genepool equate to geographic differentiation as has been suggested [79]?
Although population genetic structure and geographic differentiation have been reported for many bird species with insular distributions, high vagility typically results in high levels of gene flow and thus little local differentiation among continental populations.
These variations in frequency were consistent with the moderate geographic differentiation described above.
We consider groups A and C separate, as we assume that groups containing more than one haplotype should not show geographic differentiation of the two haplotypes.
Genotyping of microsatellite repeat markers [29] in these samples demonstrated evidence of geographic differentiation at the genome-wide level between West Africa and East/Central Africa.
Gealy et al. [58] studied the genetic diversity and structure of weedy rice from USA, where geographic differentiation among weedy rice accessions across the country was found.
While these data together suggest geographic differentiation of var genes within Africa, we have interpreted this observation with care as the paucity of shared var types may simply reflect shallow sampling in any site (Figure S2).
Natural selection can both enhance and reduce geographic differentiation.
