In evolutionary ecology (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FEvolutionary_ecology), an ecotype (Greek: οίκος = home and τύπος = type, coined by Göte Turesson (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FG%25C3%25B6te_Turesson) in 1922) describes a genetically distinct geographic variety, population or race (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FRace_%2528biology%2529) within species (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FSpecies) (or among closely related), which is adapted (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FAdaptation) to specific environmental conditions. Typically, ecotypes exhibit phenotypic (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FPhenotype) differences (such as in morphology (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FMorphology_%2528biology%2529) or physiology (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FPhysiology)) stemming from environmental heterogeneity and are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor.[1] (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FEcotype%23cite_note-0)[2] (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FEcotype%23cite_note-G.-1)[3] (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FEcotype%23cite_note-2)[4] (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FEcotype%23cite_note-Molles-3)


Ecotypes have no main taxonomic rank in modern biological classification (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FBiological_classification). However, in Environmental Encyclopedia (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fwww.amazon.com%2FE nvironmental-Encyclopedia-Marci-Bortman%2Fdp%2F0787654868%2Fref%3Dsr_1_1%3Fie%3DUT F8%26s%3Dbooks%26qid%3D1265235475%26sr%3D8-1%257C) they are said to be "taxonomically equivalent to subspecies (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FSubspecies)". This is true in the sense that ecotypes can be sometimes classified as subspecies and the opposite.http://en.wikipedia.org/wiki/Ecotype (https://www.forumbiodiversity.com/redirector.php?url=http%3A%2F%2Fen.wikipedia.org%2 Fwiki%2FEcotype)

Is ecotype the taxonomic equivalent of subspecies or race?

I'd say is an alternate term. Either way, they can name it however they want so it pleases whatever idea/criteria the people using them has, the thing is there are clusters formed.

I would equate ecotype with biotype and equivalent examples would be pygmies, tutsis, mongoloids, desert types and the extinct neaderthals, etc.

It sounds awfully like Newspeak and Political Correctness. It is like everyone is avoiding a large dog turd on the pavement, but its words like race and subrace.

No matter what you want to call your races or subraces, fair enough, use biotype. Usually I have heard biotype used for plants and insects not humans or higher animals.

Ecotypes are the subtypes within an Ecospecies. An Ecospecies is a species with subforms adapted to different environments with special physical, genetic and cultural adaptations to that environment but all subtypes are when they get together, can have fun and reproduce producing abundant and fertile offspring.

Every form of human whether Pygmoid or Neotenized or Americanoid can live in all environments, and thrive when they all use the appropriate cultural adaptations. Pygmies are not limited to their tropical jungle environments or living in commensal or parasitic relationships with Bantu speaking African farmers. Pygmies can quite happily adapt to living in America and selling their grandmothers for a hit of heroin just like the other people in America. They can adapt.

People can addapt, indeed. However, there are limitations. Many whites would preffer to live in med and colder weather rather than in humid tropical latitudes. Most Africans feel better in the tropics than in Alaska.
Most people wouldn't play soccer at 3000 meters height, like Aymaras and Quechuas usually do.
