The ecotype concept (Turesson, 1922) is a population concept, and by definition an ecotype is an intraspecific product of environmental selection arising as a result of genotypic response to a particular habitat. Accordingly, before a population qualifies for ecotype status, a relationship must be demonstrated between its heredity and the prevailing ...

Highly replicated evolution of parapatric ecotypes [PDF]
Abstract Parallel evolution of ecotypes occurs when selection independently drives the evolution of similar traits across similar environments. The multiple origin of ecotypes is often inferred on the basis of a phylogeny which clusters populations according to geographic location and not by the environment they ...

Ecotypes of the Mycobacterium tuberculosis complex [PDF]
A phylogeny of the Mycobacterium tuberculosis complex has recently shown that the animal-adapted strains are found in a single lineage marked by the deletion of chromosomal region 9 (RD9) [Brosch et al., 2002. A new evolutionary scenario for the Mycobacterium tuberculosis complex. Proc. Natl Acad. Sci. USA 99 (6), 3684-3689].

Differential Activity of Coexisting Prochlorococcus Ecotypes
The abundance and widespread distribution of the unicellular cyanobacterium Prochlorococcus is attributed to its extensive genetic diversity. At least twelve distinct clades, or ecotypes, of Prochlorococcus have been discovered so far, and follow ...
