Leaf litter, a critical habitat for juvenile Japanese giant salamander, Andrias japonicus (Amphibia: Caudata) [PDF]

open access: yes, 2018
東広島市椋梨川水系にはオオサンショウウオが生息している。2011 年から,生息状況や産卵,幼生の離散などの生態学的な調査が行われている。この過程で幼生が巣穴から離散した直後の隠れ家や餌となる水生昆虫の生息場所として流水中の落ち葉・落枝が重要な役割を担う可能性が示唆されている。本研究では流水中の落ち葉・落枝の詳細を明らかにするため,河畔林のフロラを調査するとともに,幼生が発見された場所の落ち葉との比較を行った。その結果,流水中の落ち葉・落枝として29種の維管束植物が同定できた。流水中の落ち葉 ...
