The ecological dimensions of prokaryotic speciation may be identified by comparing the ecology of the most newly divergent, ecologically distinct populations (ecotypes).
This is because the gregarines that infect crustaceans form an extremely divergent and distinct lineage within apicomplexans (and eukaryotes as a whole) as inferred from SSU rDNA.
Although the precise birthplace or mechanism of Anatomically Modern Human (AMH) emergence is still debated (Weaver 2012), consensus has been reached that 1) modern humans originated within Africa, and 2) the most divergent (genetically distinct) contemporary human populations are found within southern Africa (Li et al. 2008; Henn et al. 2011).
However with species that are more divergent, there are distinct differences between synonymous rates and UTR divergence.
Distinct forms of prion disease show differences in lymphoreticular involvement that appear to be related to the divergent properties of distinct prion strains [ 1].
Several species are composed of multiple, genetically distinctive lineages (in some cases, incipient or new species) due to independent colonization histories from distinct, divergent source populations.
This model of coexistence, based on divergent niches and distinct preferences, is a common underlying assumption in community ecology [6].
We compared 5 different diatom species from divergent classes, with distinct structures and shape to enable analysis of conserved and divergent roles of the cytoskeleton.
However, an Australian isolate of BTV-15, and the Swiss isolate of BTV-25 appear likely to represent two further divergent groups or distinct topotypes.
As gene flow does not seem to be limited by physical barriers, the observed partitioning of S. hystrix in this study supports the notion of reduced gene flow through divergent selection between distinct reef habitats.
