ture; interfertile with other ecotypes of the ecospecies, but prevented from freely
exchanging genes by ecological barriers. [Gregor et al., 1936:325] Gregor (1939:
313-14) later defined the coenospecies as: "a group of sexually reproducing ...

Taxonomy of Angiosperms
The most widely accepted categories, in order of ascending phyletic value, are
ecotype, ecospecies, cenospecies and comparium. Ecotype is the basic unit in
biosystematics, adapted to a particular environment but capable of producing
fully ...

Thus, in the same species, there may occur in nature different morphologic forms
such as ecotype, ecospecies and ecads. Ecotype — An ecotype is a population
of individuals of a species which are genetically different. The different ecotypes ...

Ecospecies Ecospecies is a unit of classification which contains one or more
ecotypes. Ecospecies and coenospecies are two parallel terms. According to
Gregor (1940), eco- species is a unit of genecological classification; in other
words, ...
Along the continuum from the most restricted to the most ubiquitous species, only
four ecospecies could be considered as truly widespread and occurring in at

The simultaneous occurrence of ecological differentiation and sterility barriers
justifies the conclusion that the intraspecific chromosome races may be classified
as ecospecies. In several cases of experimental autopolyploidy the polyploid ...
The ecospecies maintains its integrity through a combination of ecological and
genetic mechanisms. The genetic barriers between ecospecies are somewhat
less effective than those found between cenospecies, but these barriers are ...
