stasipatric speciation

Japanese: stasipatric speciation(英語表記)stasipatricspeciation
stasipatric speciation

...For example, two species may live in the same area or forest, but reproductive isolation may be established due to differences in special wing patterns, voices, or courtship behavior. In addition, MJD White (1968) discussed the process of true sympatric species differentiation in a part of a population of a grasshopper species (genus Keyacris ) in which related mutations in morphology, behavior, physiology, etc. occur intensively due to external factors, forming the nucleus of a new species population, which then expands into speciation, and he named this process stasipatric speciation. However, in this case, too, Mayer believes that species differentiation occurred through ecological allopatricity due to the tendency of the population to gather in a specific ecological environment, and that completely sympatric species differentiation is not possible. ...

…例えば,同じ地域や林に2種が生息しても特別な羽斑や声や求愛行動などの違いで生殖隔離が成立する場合などである。また,ホワイトM.J.D.Whiteは真の同所性種の分化の例として,バッタの1種(Keyacris属)の個体群の一部分で外因などによって形態,行動,生理などの関連した突然変異が集中的に起こって新種個群の核ができ,種形成に拡大する過程を論じ(1968),これを静的種形成stasipatric speciationと名づけた。しかし,この場合も,その個体群が特定の生態環境に集まる指向性によって,生態的異所性を経て種の分化が起こったと考えられ,完全な同所性種の分化はあり得ない,とマイヤーは考えている。…
