DigiFish: A flexible open-source tool for animating realistic virtual fish and reconstructing visual fields from tracking data

DigiFish creates realistic virtual fish animations and reconstructs visual fields from tracking data to study visually guided behavior.

Perceptual constraints of motion shape animal movement strategies

This study shows that fish adjust their movement strategies to optimize prey detection by balancing motion-induced perceptual costs and benefits.

Group personality, rather than acoustic noise, causes variation in group decision-making in guppy shoals

This study shows that group personality, not acoustic noise, drives variation in decision-making and cohesion in guppy shoals.

Enhanced conspicuousness of prey in warmer water mitigates the visual constraint of turbidity for predators

This study examines how temperature and turbidity affect prey detectability by predators, finding that warmer water increases prey conspicuousness, counteracting the negative effects of turbidity.

Visual lateralisation in female guppies demonstrates social conformity but is reduced when observing a live predator

Shoal cohesion and polarisation increase in turbid water and improve foraging performance

This study shows that fish shoals become more cohesive and coordinated in turbid water, which enhances their foraging performance despite slower responses in clear water.

Does temperature, light or inter-individual variation explain feeding motivation in a tropical freshwater predator?

This study examines how temperature, light, and individual variation affect feeding motivation in pike cichlids, finding no environmental effect but consistent individual differences.
