Outline of Final Research Achievements |
This study focused on the occurrence of various taxa of parasitic isopods and discussed the morphology of appendages and eyes, their presence or absence, and the fusion state of body segments, together with ecological characteristics such as selection of parasite sites, conversion, and host selection, in an attempt to contribute to parasitology as a whole through taxonomic research. Through phylogenetic and taxonomic studies of isopods, I attempted to clarify the process from free-living to external and internal parasitism, what events occurred, and whether these events could be applied to parasites as a whole. As a result of specimen surveys and collection surveys using research vessels and at museum facilities, I was able to obtain many parasitic isopods and describe the degree of parasitic adaptation.

Academic Significance and Societal Importance of the Research Achievements |
本研究は動物の自由生活性から寄生生活性への進化プロセスを明らかにすることである。その中でも等脚目甲殻類では、生活史のほとんどで寄生生活を行う群から生活史の一部で寄生生活を行う群を含み、また形態に様々な程度の寄生適応がみられることから当該課題の解明に適した材料である。今回の成果では目全体の系統関係や進化プロセスを明らかにするところまでは行かなかったが、個別の分類群の形態の寄生適応の程度を検討することができた。他の分類群の寄生性動物のデータと比較することによって、より一般的な議論に発展させることができるものと考える。
