種内の
解説 Definition
同じ種に属する個体間で起こる関係や現象、違いを表す形容詞です。生物学で、同一種の個体どうしの競争や変異などを説明するときに使います。
Intraspecific means happening within a single species, not between different species. It is used in biology for things like competition, variation, or breeding among members of the same species. This is a technical scientific adjective.
使い方 Usage
- intraspecific competition「種内競争」、intraspecific variation「種内変異」などの形で使います。 Common phrases include intraspecific competition and intraspecific variation.
使い分け Common distinctions
- intraspecific は「種内の」、interspecific は「種間の」。intra-「内」と inter-「間」を区別します。 Intraspecific means within one species; interspecific means between different species. Distinguish intra-, within, from inter-, between.
覚え方のコツ Memory Tip
intra- は intranet と同じ「内部」の感覚です。specific を species「種」と結びつけ、「一つの種の内側」と覚えましょう。
Link intra- with the idea of within, as in intranet. Connect specific with species and picture something happening within a single species.

intraspecific の語源・成り立ち Etymology
intra-は「内側」、specificはspecies「種」に由来し、speciesはさらにラテン語specere「見る」へさかのぼる。つまり『見分けられた種類の内側』が原義で、同じ種の内部で起こることを指す。speciesやspecimenも同根。
Intraspecific is formed from intra- "within" and specific, which comes from Latin species, "kind" or "type." Species is linked to a root meaning "to look" or "to see," because kinds were things distinguished by appearance. So intraspecific came to mean "within the same species"; compare species and specimen.
