 研究について

  ヘビ類は3500を超える全ての種が動物を餌としており、多くの生態系において脊椎動物や節足動物、軟体動物など多様な動物の主要な捕食者となっています。私は採餌をはじめとするヘビ類の行動・生態を野外調査や室内実験によって調べ、行動上の適応や他種との相互作用を明らかにする研究を行っています。現在の主な研究テーマは次の通りです。
【現在の研究テーマ】
・ヤマカガシの採餌と餌由来の毒を使った化学的防御
・メクラヘビの採餌
・マダガスカルにおけるアリとヘビの共生

Snakes are a diverse group which includes more than 3500 species. All snakes are carnivorous, and they are major predators of vertebrates, arthropods, mollusks etc. in many terrestrial and some aquatic ecosystems. I study snakes’ behavioral adaptations and interactions with other species through investigating their behaviors both in fields and laboratory.

My current projects include:
・Chemical defense and foraging ecology in snakes that sequester defensive compounds from their diets
・Feeding in blindsnakes
・Symbiosis between ants and snakes in Madagascar
