Welcome to the Animal Ecology Laboratory! Our research interests are in evolution of animal behavior. We will use traditional behavioral study methods such as filed observation and aquarium experiments, as well as using the latest techniques for molecular biology to approach wonders of animal behavior.
1. Diversity of mating patterns and sex roles in Syngnathid fishes
Specific projects include:
- Intraspecific geographical variation in mating pattern
- Behavioral genomics of pair-bonding in a monogamous pipefish
- Polyandrous mating and sex-role reversal in a seagrass-dwelling pipefish
- Phylogenetic constraints on mating pattern in syngnathids
2. Cognitive capacity and social behavior in teleost fishes
Specific projects include:
- Individual recognition and adaptive behavioral adjustments in a gobiid fish
- Effects of familiarity on social learning in group-living fishes
- Partner recognition in a monogamous pipefish
- Cleaning symbiosis between a facultative cleaner and client
3. Other research projects
- Genetic population structure of endangered fishes
- Origin and diversification of parasitic isopods
- Application of environmental DNA techniques for fisheries resources management
