Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Area of Science:

Ethology
Robotics
Neuroscience

Background:

Zebrafish (Danio rerio) are key models for studying fear and anxiety.
Traditional fear studies use live predators, posing challenges due to inconsistent behavior.
Robotic stimuli offer controlled and repeatable experimental conditions for behavioral analysis.

Purpose of the Study:

To investigate the role of closed-loop control in modulating zebrafish fear response.
To develop a novel robotic predator system for real-time, interactive behavioral studies.
To advance the understanding of animal-robot interactions in fear research.

Main Methods:

Designed a 3D-printed robotic replica of Astronotus ocellatus (red tiger Oscar fish).
Implemented a closed-loop control system using a finite-state Markov chain for real-time stimulus response.
Analyzed zebrafish ethograms and interaction information-theoretic quantification.

Main Results:

Closed-loop control successfully elicited consistent fear responses in zebrafish.
Zebrafish demonstrated adaptive behavior, adjusting actions to evade the robotic predator.
The system quantified the interaction dynamics between zebrafish and the robotic stimulus.

Conclusions:

Closed-loop robotic control enhances the study of fear responses in zebrafish.
This interactive system represents a significant advancement in animal-robot interaction research.
The developed paradigm offers new possibilities for investigating fear and anxiety in animal models.
