Research Interest
I aim to understand animals' mode of life by analyses at the individual level. Brown rats (Rattus norvegicus) are one of the wild animals that have coexisted with human populations for thousands of years. In addition, laboratory rats, domesticated brown rats, are one of the major experimental animals in the world. However, surprisingly, little is known about their mode of life. I am currently studying both laboratory rats and wild brown rats to understand their social lives.
In laboratory rats, I focus on two chemical communications. One is the "alarm pheromone" that is released by stressed rats and augments anxiety responses in others. The other is the appeasing pheromone that induces "social buffering," a phenomenon in which the presence of affiliative conspecifics mitigates a variety of stress responses in others. These communications may be the basis for the social lives of wild brown rats.
In wild brown rats, I am studying "neophobia," the avoidance of novel objects and/or familiar objects moved to a novel position. This behavior enables wild brown rats to avoid danger, including traps and rodenticides, in their lives. In addition, because they are a major pest, we can obtain the records of culling campaigns and complaints from collaborating pest management companies and associations (e.g., the record of campaigns in Tsukiji Market). These data provide information about the ecological dynamics of the target population.
Even today, brown rats are one of the major risks to public health and livestock industries. Therefore, the analyses of brown rats' mode of life would be a contribution to society from the field of veterinary medicine and animal life science.
