          • Definition(s)
            • 一般的には相互に交配する集団（地域繁殖集団）が群れと見なされる。これをデームと呼ぶ事もある。しかし実際には交配可能な集団の内部に、より小さな集団が存在することもある。このばあい、古典的な群選択はデーム間群選択と呼ばれる。これは上述したように限られた状態でしか起こらないと考えられている。デーム内の小集団の間で起きるデーム内群選択は血縁選択と同じものだと考えられている[7]。 Wikipedia　郡選択 - by stock

            • Ugyanazon rendszertani kategória (taxon) szervezeteinek egy csoportja. A kifejezést különféle előképzőkkel együttesen használják annak megjelölésére, hogy miben különbözik ez a csoport a többiektől. Például egy ökodém egy sajátos ökológiai élőhelyen előforduló helyi populáció; a citodém a többiektől sejttani felépítésében tér el; a genodém örökletes tulajdonságaiban más.

S. WILSON 1975, 1977). - A TÁRSAS MAGATARTÁS EVOLÚCIÓJA by Levente Bodrossy Dr.

          • Definition(s)
            • Categoria più ristretta dell’ecotipo. È l’unità di popolazione più piccola, formata da gruppi di individui geneticamente molto simili, uniti uno all’altro da un interno rapporto temporale e spaziale. Si tratta di porzioni molto ristrette di popolazioni parzialmente isolate. Deme (accezione comune): sottopopolazione Suffisso ‘-deme’: gruppo di individui appartenenti a una categoria tassonomica specifica Scienze della Terra - by texjax DDS PhD
          • Example sentence(s)
            • Natural species are often composed of subspecies that differ conspicuously except in the zones of intergradation, and these are likely to be subdivided into local races with market statistical differences and so on in hierarchic fashion to ones with only slight statistical differences. The ultimate unit is the more or less completely isolated local population or deme (Gilmour and Gregor 1939) within which breeding may usually be treated as occurring at random. It is very unusual for a whole species to consist in a single deme. […] The effective size of a deme is often so small that the recurrence rates of mutations are likely to be negligibly small even over considerable periods of time. On the other hand, immigration of individuals from other demes, followed by crossbreeding, must nearly always be a very important factor in their histories. - Evolution and the Genetics of Population by texjax DDS PhD
            • “Demes” are groups of individuals who are more genetically similar to each other than to any other individuals. - Responsible Genetics by texjax DDS PhD

            • Çoğu türün çok sayıda daha küçük soy içi çiftleşen “deme” adı verilen popülasyonlardan meydana geldiğini anımsamak da önemlidir. - apoptozis by Selcuk Akyuz
            • Bir türün aynı coğrafik bölge içinde bulunmalarına karşılık çeşitli nedenlerle birbirlerinden ayrılmış topluluklarına da lokal ırklar denir. Lokal ırkların oluşturdukları topluluklara deme adı da verilmektedir. Yani bir tür, birbirleriyle bazı yakınlıkları olan sayısız lokal populasyonlardan ya da demelerden meydana gelmektedir. - AOF by Selcuk Akyuz
