Outline of Final Research Achievements

The precise ant mimicry of Myrmarachne jumping spiders (Salticidae) has been attributed to their high defensive effectiveness against predators. In this study, we found that the ant mimicry of Myrmarachne spiders reduces their ability to capture prey and shifts their diet to a plant-based source, and that the spider species have the habit of remaining close to their mimetic model ant species, which indicates the possibility of the spider using the nectar glands and other food sources monopolized by the mimetic model ant species in their territory. Furthermore, our DNA phylogenetic analysis revealed that speciation to the same mimetic model ant species occurs repeatedly in different phylogenetic lineages of Myrmarachne jumping spiders. These findings suggest that ant mimicry in Myrmarachne jumping spiders is a strategy for coexistence with mimetic model ants and a mechanism for creating species diversity in the spider genus.

Academic Significance and Societal Importance of the Research Achievements

擬態は,これまで捕食者に対する防衛戦略として解明が行われてきた。本研究の学術的な意義は,アリグモ属のクモ類の正確なアリ擬態が,その食性を肉食から植食に転換させていることや,捕食者ではなく擬態モデルとの関係の中で進化してきたこと明らかにすることで,擬態研究に生物多様性創出や多種共存機構という新たな研究領域を開いた点にある。また,本研究成果は熱帯林で得られたものであり,その成果は,なぜ熱帯で高い生物多様性が創出され維持されているのかという生物学における主要な課題の解明や,熱帯林の生物多様性保全に貢献できるものである。
