Olympic village effect

名詞

不可算名詞

(evolutionary biology) A selection effect driving evolution of an invasive species at the invasion front, that selects the fastest and furthest invaders to interbreed creating stronger and faster invaders, due to the invasion front preselecting the fastest invaders, concentrating these individuals and therefore selecting those traits that let them invade faster.

日本語の意味

侵入前線において、最も速く遠くへ侵入する個体が選択され、交配を通じてより強靭で速い侵入個体が生み出される現象。 / 進化生物学における選択効果の一つで、侵入種が進行中の侵入前線で、個体の速度と拡散距離に基づき進化的に有利な形質が集積・増幅される現象。

Biologists documented an Olympic village effect at the invasion front, where the fastest dispersers clustered and interbred, producing offspring that were ever faster and more invasive.

生物学者たちは、侵入前線で最も速く移動する個体が集中して交配することで、より速く侵略性の高い子孫が生まれるという選抜効果を記録した。
