Ecotype vs. Ecad — What's the Difference?

In evolutionary ecology, an ecotype, sometimes called ecospecies, describes a genetically distinct geographic variety, population, or race within a species, which is genotypically adapted to specific environmental conditions. Typically, though ecotypes exhibit phenotypic differences (such as in morphology or physiology) stemming from environmental heterogeneity, they are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor.

(ecology) An organism whose form has been affected by its environment.

A genetically distinct population of plants, animals, or other organisms that is found in a particular habitat.

A non-inherited somatic modification caused by an organism's environment.

(ecology) A phenotype that is adapted to a specific environment.
