Proceedings of the 76th Annual Meeting of The Entomological Society of Japan and the 60th Annual Meeting of the Japanese Society of Applied Entomology and Zoology: 218.] (Part of my undergraduate thesis, I conducted laboratory experiments to confirm the interaction between prey springtails and predatory ants in soil, clearly demonstrating that ants exhibit predatory selectivity.)

Abstracts of the 2017 Annual Meeting of the Kansai Entomological Society and the 156th Meeting of the Kinki Branch of the Lepidopterological Society of Japan: 6. (This is part of a master's thesis in which the diversity of soil animals, especially ants, was investigated in detail within Minoh Park. In addition, the distribution and impact of the domestic alien species Odontomachus monticola, in its early stages of invasion, were evaluated using community ecological methods, and it was shown that its impact was minimal at the time of the investigation.)
