Temperature and turbidity interact synergistically to alter anti-predator behaviour in the Trinidadian guppy

This study shows that increased temperature and turbidity together reduce guppy shoaling and increase predator proximity, increasing predation risk.

A novel method for investigating fish social behaviour in the field

This study introduces a novel method using funnel traps to quantify social behavior in wild fish, finding seasonal and temperature-related changes but limited phenotypic assortment.

Predatory fish preferentially target virtual prey with Levy motion rather than Brownian motion

This study shows predatory fish target virtual prey with Levy motion more than Brownian motion, highlighting predation risk as a factor in movement strategy efficiency.

Personality variation is eroded by simple social behaviours in collective foragers

The paper shows that social interactions can reduce individual personality differences in foraging groups by altering group movement patterns.

The measure of spatial position within groups that best predicts predation risk depends on group movement

This study compares spatial position measures in groups of prey to predict predation risk by sticklebacks, finding that different measures are best in stationary vs. moving groups.

Responsive robotic prey reveal how predators adapt to predictability in escape tactics

The paper shows that predators adjust their behavior to maintain capture efficiency despite prey predictability, with no net effect on capture time.

Emergence of variation between groups through time in fish shoal collective motion

The paper examines how collective motion traits in fish shoals change over time and finds increasing inter-group variation and reduced cohesion and polarisation.

The impact of turbidity on foraging and risk taking in the invasive Nile tilapia (Oreochromis niloticus) and a threatened native cichlid (Oreochromis amphimelas)

This study examines how turbidity affects foraging and risk-taking behaviors in invasive Nile tilapia and threatened native cichlid fish, finding species-specific responses to environmental changes.

Fish avoid visually noisy environments that reduce their perceptual abilities

Fish avoid visually noisy environments by increasing activity in noisier areas, reducing their ability to detect prey, but not increasing exploration.

Early prediction of declining health in small ruminants with accelerometers and machine learning

This study uses accelerometers and machine learning to predict health decline in small ruminants, achieving up to 83% precision in detecting changes in FAMACHA scores.

State-behavior feedbacks suppress personality variation in boldness during foraging in sticklebacks

This study shows that foraging suppresses personality variation in boldness in sticklebacks through state-behavior feedbacks, with bolder fish showing greater variation in refuge use during feeding trials.

Predatory behaviour as a personality trait in a wild fish population

The paper shows that individual pike cichlids differ consistently in their response to prey, indicating a predator personality trait independent of other traits and environmental factors.

Counteracting estimation bias and social influence to improve the wisdom of crowds

The paper improves collective estimation accuracy by addressing individual biases and social influence through new aggregation methods.
