研究実績の概要

Anthropogenic land use changes have the potential to drive shifts in populations of ticks, hosts animals, and pathogens. The impacts of land use changes on the abundance and diversity of tick populations were studied in Hokkaido, Japan. Two pairs of systems were compared, namely conifer plantations with native mixed forest, and pasture with native mixed forest. Ticks were sampled within standardized quadrats monthly from May-June in the conifer plantation-native mixed forest system; and monthly from May-September in the pasture-native mixed forest system. In total, 8 tick species were identified representing two genera, Ixodes and Haemaphysalis. Statistical analysis is ongoing and due to be completed by July 2024 after which the results of both studies will be written up and published.

2: おおむね順調に進展している

理由

The study sites were assessed and chosen in late 2022 in Shinhidaka and Furano, Hokkaido. All fieldwork was completed successfully in 2023. Samples were identified and data was processed in early 2024. Statistical analysis is presently underway with writing scheduled to begin in July 2024 and submission to peer-reviewed journals in August 2024. While this has been occurring, I have authored 8 peer-reviewed publications, of which 5 were directly supported by the JSPS. The support of my host researcher has been invaluable, important, and unwavering. With his continued support and that of the JSPS I will be able to easily complete the two aforementioned studies and submit them for peer-review before the end of my fellowship in September 2024.

今後の研究の推進方策

I intend to complete the two studies I initiated as part of my JSPS postdoctoral fellowship by August 2024. Alongside these I am in the process of completing approximately 6 other manuscripts, with a further two others already submitted to peer-reviewed journals and under review at present. JSPS will be acknowledged in all of these studies.

I intend to use the experiences, relationships, and skills gained during my fellowship to work towards eventually gaining a permanent academic position in Japan to continue my research here and to contribute to Japan as an academic, particularly in relation to the study of zoonoses and disease ecology.
