This study shows how measurement practices affect repeatability estimates of individuality in clonal fish, highlighting methodological influences over biological variation.

The paper shows that behavioral differences in genetically identical fish can be transmitted across generations without genetic or environmental influences.

The paper tracks early-life activity in genetically identical fish to show it predicts lifespan variation, finding a U-shaped relationship between activity levels and longevity.

This study tracks behavioral plasticity in genetically identical fish clones over four weeks, finding an initial increase in plasticity before it decreases, challenging the expectation of decreasing plasticity in stable environments.

The paper tests for paternal effects in a gynogenetic fish species and finds no evidence of paternal influence on offspring or brood size.

The paper examines how perceived predation risk influences among-individual behavioral variation in Amazon mollies, finding reduced variation in predator-exposed groups.
