ur goal is to elucidate the functions, mechanisms, ontogeny, and evolution of behavior, which are the four questions of ethology. The target animals are diverse, ranging from invertebrates such as insects to vertebrates such as reptiles, amphibians and birds. We use field observations and laboratory experiments according to the purpose of the research. While keeping in mind that knowledge about the natural history of the target animal is essential, we conduct research based on behavioral observation at the individual level. Currently, two faculty members are conducting the following research:

Study on the function and evolution of snake foraging behavior and anti-predator behavior (Akira Mori)

I am mainly studying the function and evolution of snake foraging behavior and anti-predator behavior on two topics. The first is about yamakagashi (also known as tiger keelback), which has the nuchal glands. The nuchal glands are unique organs for defense, and I study anti-predatory behavior of the snake and the structure and physiological mechanism of the nuchal glands in collaboration with Kyoto University Graduate School of Agriculture and overseas universities. In particular, with focusing on the fact that the nuchal gland toxins are sequestered from toads or fireflies consumed as food, we are engaging in behavioral and ecological studies related to the reuse of prey toxins. In addition, we are exploring the evolutionary process and diversification of the nuchal glands-dependent defensive system through comparative studies with species in foreign countries. The second topic is a long-term field study on the foraging ecology of Hime habu, also known as Okinawa pigmy pitviper, investigating the movement pattern to the foraging site and the fidelity of each individual to the ambush site for more than 20 years.

Study on the function and evolution of communication in geckos (Teppei Jono)

I am conducting a wide range of behavioral and ecological studies of reptiles and amphibians, with a main focus on gecko communication. Recent topics include inter- and intra- specific variation in　reproductive traits of Gekko japonicus species group, the function of male-specific glands, and the ecological significance of the loss of species-specific patterns of courtship calls.

In addition to these studies, 16 graduate students are working on a wide range of issues such as research on foraging behavior, anti-predator behavior, and interspecific communication of insects, amphibians, reptiles, and birds.
