Defensive behavior of prey animals in a closed system: experimental approach using amphibian larvae (Osamu Kishida)
How do animals living in the closed systems behave for success of their life? In this study, I investigate condition-dependent tactics of pond-dwelling amphibian larvae. In particular, I conduct the robust aquarium experiments to reveal behavioral patterns of amphibian larvae under predation (cannibalism) risk and their ecological consequences.
Understanding navigation in small fishes by optical measurements and manipulation of cerebellar activity (Sachiko Tsuda)
We will examine how collective behavior is formed, focusing on the neuronal basis and environmental factors. For this, we apply functional imaging, optical manipulation, and behavioral analysis to zebrafish.
The multifunctionality of swarms with diverse personalities: Meta-genetic basis and the control of collective behavior (Yuma Takahashi)
The swarm of animals are consisted of diverse personalities. Our study examines the effects of behavioral, physiological, and ecological diversity within a swarm on the dynamics and ecological performance of the swarm in fruit flies.
Understanding hierarchical navigation by the multidimensional sense of loggerhead turtles migrating in the sea (Kentaro Sakamoto Q.)
Loggerhead turtles migrating in the sea are thought to make movement decisions through a hierarchical navigation mechanism according to the movement scale. In this research, we aim to elucidate the navigation mechanism by accurately measuring the behavior related to the navigation of sea turtles and artificially intervening in the behavior by using innovative technology.
Individual-population behavioral hierarchy of solitary mammals considering individual differences in CPS (Shinsuke Koike)
By using the Cyber Physical System (CPS), we aim to elucidate the factors that cause animal behavior and their relationships, taking into account individual differences, as well as the individual-population hierarchy through behavior diagrams. Specifically, factors governing behavior and their relationships will be clarified using AI based on existing bear behavior and environmental information, and factors that trigger synchronized behavior among individuals will be ascertained.
Behavior traits and neural control mechanisms underlying the diversification of group characteristics (Ryoya Tanaka)
Diversification of group characteristics plays a major role in animal species' life history and environmental adaptation. In this study, we focus on Drosophilinae insects to reveal the individual behavioral traits and their neural control that lead to the diversification of group characteristics.
Cooperative hunting behaviors in dolphins with appropriate bimodal sensing (Tadamichi Morisaka)
My goal for this study is to understand the complex cooperative hunting in dolphins, top predator in marine environment, towards the gregarious fish with both echolocation and vision. I will study two types of researches; one is in the aquarium to understand how dolphins use echolocation and vision separately, and the other is in the wild to describe the behavioral variations of cooperative hunting towards gregarious fish.
Studies on the movement patterns of small cetacean, finless porpoises, off the coast of Japan and the effects of ships on their behavior (Satoko S. Kimura)
I am developing monitoring methods for quantitative observation of large aquatic animals, mainly small odontocetes (dolphins and porpoises). These methods are used to reveal their behavior and ecology, and to assess anthropogenic impact on the species or individuals. By using passive acoustic monitoring methods that utilize the sounds produced by animals and biologging methods that attach equipment directly onto the animals, I am examining the characteristics of the sounds produced by the target species, their vocal behavior, and basic ecological information such as when, where, and how many target animals are present at the target waters. I am also conducting EIA of noise from ship traffic and offshore wind power plant on the animals, stress check in captivity, and drone surveys in the wild.
Intra-group and inter-group interaction in multi-level society of feral horses (Shinya Yamamoto)
I study a wide variety of animals, including chimpanzees, bonobos, horses, and dogs, incorporating a wide range of methods and viewpoints from hormones to cognition, behavior, society, and ecology. Using drones, we have found a multilayered structure in feral horse society. By investigating intra-group and inter-group behavioral coordination, I will elucidate the mechanisms of collective behavior in a multi-level society.
Elucidation and modeling of insect navigation strategy in response to hierarchical changes in environmental and body dynamics (Shunsuke Shigaki)
This research aims to identify an insect adaptive controller when the environment and body dynamics change hierarchically by using Animal-in-the-Loop, a system in which a robot is teleoperated by the insect. This enables the construction of an artificial system that can move without compromising its navigation function even when the complexity of the environment and body characteristics change drastically.
Elucidation of defense strategy of scallops by the group formation (Koji Miyoshi)
This is the first study reporting on a school of scallops exhibiting a chain reaction of escape responses to approaching predators. Here, the relationship between escape strategies of scallops and survival rates in solitary and group life and the conditions for group formation as a defense strategy will be elucidated.
