First term
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.
Second term
Identification of environmentally adaptive behavioral selection processes in an insect by using digital twin technology (Shunsuke Shigaki)
In this study, we utilize a virtual reality system for insects based on digital twin technology to obtain the relationship between sensory stimuli and behavioral outputs of an insect in various spaces. Moreover, we employ AI-based analysis methods to clarify what states or conditions are valued when the insect chooses actions.
Studies on the pursuit strategy and the guidance laws in penguins and other animals for capturing prey using animal-borne dataloggers (Yuuki Kawabata)
It is not easy to measure the pursuit strategy (geometric rules) and guidance law (how they navigate themselves along these paths) of animals in the wild. In this study, we aim to reveal the pursuit strategy and guidance law of penguins using animal-borne dataloggers and to explore its application to other animals.
Neural mechanisms controlling the decision to switch between grouping and non-grouping in Drosophila species (Ryoya Tanaka)
Group formation is a critical survival strategy in animals. Each species is expected to flexibly switch whether or not to form a group, depending on their life history and habitat environment. In this study, I examine the individual navigation and neural functions that control the switching of group formation using Drosophila.
Elucidation of the hierarchical navigation mechanism involved in "migration" of large terrestrial mammals (Shinsuke Koike)
We aim to elucidate the actual conditions of long-distance migration of large mammals (bears and deer) using GPS receivers and to elucidate the factors that cause these behaviors and their relationships, taking into account individual differences, and the hierarchy between individuals and populations via behavioral diagrams.
Optical analysis of the hierarchical dynamics of schooling in small fish (Sachiko Tsuda)
We will focus on the neural basis and environmental factors to understand how the hierarchy in collective behavior is formed. To elucidate the regulatory mechanisms of hierarchical navigation in animals, we will combine optical approaches, behavior analysis, and informatics.
Elucidating the Growth-Dependence of Predation Avoidance Mechanisms in Scallops (Koji Miyoshi)
This study aims to investigate predation avoidance behavior and the development of inter-individual cognitive mechanisms in scallops. It aims to understand the impact of these behaviors on population dynamics and to contribute to marine resource management.
Cooperative hunting in dolphins achieved through visual and auditory coordination (Tadamichi Morisaka)
The goal of this research is to understand the cooperative hunting of schooling fish by dolphins, apex predators in the ocean, utilizing simultaneous sensing through vision and echolocation. It will explore how visual and auditory senses coordinate during captive feeding and observe individual behaviors and interactions during wild cooperative hunting, including behavioral variations among different fish species.
Use of environmental DNA to reveal the navigation ability of hatchery-raised Ayu (Seiji Miyazono)
I study the relationships between the environmental DNA of hatchery-raised Ayu and environmental factors and reveal which environmental factors could affect the migration patterns of Ayu in a riverine system.
Functional analysis of avian magnetic compass (Kim Suhyang)
Migratory birds can fly over the great distance recognizing their own location without maps. In this study, I will investigate the molecular mechanism of the "Magnetoreception", which gives this surprisingly advanced navigation capability.
Neural mechanism of cognitive map related to autonomously moving objects (Naoyuki Sato)
Cognitive map, or the memory of spatial environments, is known to associate with imagery self-navigation, while its contribution to other autonomously moving objects has not been evaluated. In this study, we evaluate neural mechanism of the cognitive map with the autonomously moving objects by using a virtual reality environment and electroencephalogram measurement.
Inter-population and inter-species comparison of collective behavior in multilevel societies (Tamao Maeda)
Using drones, I study on collective behavior of multilevel social groups in animals. I mainly study on feral horses, but I am trying to expand my focus on other species.
Neural mechanisms of navigation system utilize the laterality in predation behavior (Yuichi Takeuchi)
Predators that attack animals have evolved sophisticated behavior and morphology so that they can prey efficiently. One form of that is laterality of predation behavior, in which predators attempt to prey primarily on one side of the body. Here, I use the scale-eating fish Perissodus microlepis, which forages by tearing off fish scales, to examine the neural basis of predation navigation that utilizes laterality, as well as the influence of acquired effects on laterality.
Understanding hierarchical interactions in group-housed mice using long-term tracking (Shohei Ochi)
By tracking and measuring the behavior of mice in a group housing environment, we aim to estimate group networks. We will intervene the group of mice by incorporating autism spectrum disorder model mice (with potentially lower sociability) and isolating acclimatized individual mice to know group dynamics. Our approaches will help unravel the mechanisms leading to the formation of group interactions.
Development of Population Size Estimation Considering Abalone Movement and Fisher's Behavior (Yukio Matsumoto)
Estimating the population size of target species is essential for stock management. The population size is estimated based on the number of catches, but the catch is affected by behavior of fishermen and target species. The objective of this study is to develop an estimation method considering the abalone locomotion and the fisher’s behavior depending on the kelp forest change.
