Outline of Final Research Achievements

(1) We developed novel microsatellite markers for some androdioecious barnacles. We also compared the reproductive success and other reproductive characteristics of males and hermaphrodites in them. (2) We performed interspecific comparisons of sexual systems in many barnacle species. (3) We showed by transplanting experiments that sexual expressions are plastic to some extent in two androdioecious species. (4) We theoretically analyzed the evolutionary transitions from hermaphrodites to dwarf males, and reviewed both theoretical and empirical studies on sexual systems in barnacles.

Academic Significance and Societal Importance of the Research Achievements

フジツボ類の性表現については未知のことが多く，本研究の成果によって，当該分野は理論・実証研究とも，かなり進展したと言えるだろう。フジツボ類は性表現が多様で，動物における性の多様性を考えるうえで重要な位置を占めるため，本成果は，動物の性全体を理解する上でも有用である。本研究を進めるうえでデンマークや台湾など複数の研究者の参画も得られ，本研究はフジツボの性を研究する国際的な研究チームを形成する核となった。
