| Outline of Research at the Start |
Often ostracods are often the most abundant micro-crustacean found in rice fields. However, their ecological role and impacts on rice harvests are poorly known, and some may be invasive in Japan. This project is designed to clarify which species live in rice fields and their potential invasiveness.
|
| Outline of Final Research Achievements |
Our research resulted in a better understanding of ostracods inhabiting rice fields, and the discovery of two new ostracods species from rice fields, one of which we have described, and the second one we are working on. We have identified a possible route for invasive ostracod species to enter and become established in Japan, namely the pet trade, and these species have the potential to become invasive in Japanese rice fields.
|
| Academic Significance and Societal Importance of the Research Achievements |
As rice is the staple food in Japan, it is essential to fully understand the rice field ecosystem. Yet ostracods, which are often abundant in rice fields, are poorly studied, and their impacts on rice harvests not fully understood. This project aimed to address this issue.
