They are commonly used in population genetic studies because of their ability to differentiate recently diverged groups (e.g., Echt et al., 1998), to function as a DNA barcode (e.g., Kuang et al., 2011), to allow for the quick identification of a genetic group or species (e.g., Decroocq et al., 2004), and to study hybridization and introgression (e.g., Wallace et al., 2011).
Yawata, Y. et al. Competition-dispersal tradeoff ecologically differentiates recently speciated marine bacterioplankton populations.
Yawata Y, Cordero OX, Menolascina F, Hehemann J-H, Polz MF, Stocker R. Competition-dispersal tradeoff ecologically differentiates recently speciated marine bacterioplankton populations.
In the present study, SSR revealed a large number of alleles (Additional file 3) in the collection and efficiently differentiated recently evolved cultivars.
Thus, there is no doubt that adding the data from different loci would result in more precise delimitation of biological species, including those that have differentiated recently, although the cost and effort would also increase substantially.
Understanding the geographic origin of an M. tuberculosis DNA fingerprint could be useful, especially in understanding the sources and spread of strains in the U.S. foreign-born population, among whom differentiating recently transmitted disease from reactivation of a past exposure can be difficult.
Modifications to the original assays by the addition of group-specific inhibitors are presented to ensure the specificity of the assays and to further differentiate between recently identified PLA2s.
Particularly in the case of poorly studied marine invertebrate groups, genetic methods can enable researchers to differentiate between recently introduced exotic species that should be monitored and controlled, and long-established, cryptic species that may have been previously overlooked and that may even require protection.
We interpret that the first populations to merge when the genetic distance threshold is raised from zero are the ones that differentiated more recently.
A limitation of this method is in the case of differentiating between recently duplicated isogenes with coding sequence exceeding 98% identity, and thus expression values in these instances should not be considered definitive.
He does not differentiate between anybody". Recently, I had trouble sleeping for weeks.
