Predator metamorphosis and its consequence for prey risk assessment
Wood frog tadpoles can generalize learned antipredator responses across the life stages of some predator species but not all. When individuals were conditioned to recognize the odor of larval or adult predacious diving beetles as risky, they subsequently showed antipredator response to the odor of both life stages. However, tadpoles did not generalize their learned responses across the life stages of the tiger salamander.
Effects of early predation and social cues on the relationship between laterality and personality
Our latest study shows that laterality and personality are linked, regardless of early environment conditions. By manipulating predation and social environment, we influenced the degree of both laterality and personality, while the correlation between them was not affected. Short-term context seems to be more important in influencing the relationship between laterality and personality than early development.

Sexual selection: competition for resources provided by mating partners
Sexual selection theory is a cornerstone of behavioral ecology and evolutionary biology, but 150 years after Darwin’s original conception, researchers are still struggling to find a consensus on what sexual selection actually is. In this review, I discuss various limitations of the gamete-centered definition of sexual selection and propose an alternative one, which defines sexual selection as competition for access to reproductive resources provided by the mating partner.
