We published a study recently testing the link between brain size and behavioural plasticity using brain size selected guppy (Poecilia reticulata) lines (Herczeg et al. 2019. Journal of Evolutionary Biology 32(3):218-226). Only large brained fish showed habituation to a new, perceived as risky, but actually harmless environment by increasing moveme...
Most studies on animal personality evaluate individual mean behaviour to describe individual behavioural strategy, while often neglecting behavioural variability on the within-individual level. However, within-individual behavioural plasticity (variation induced by environment) and within-individual residual variation (regulatory behavioural precis...
Behavioural consistency within and across behaviours (animal personality and behavioural syndrome, respectively) has been vigorously studied in the last decade, leading to the emergence of “animal personality” research. It has been proposed recently that not only mean behaviour (behavioural type), but the environmentally induced behavioural change...
Understanding the background mechanisms affecting the emergence and maintenance of consistent between-individual variation within population in single (animal personality) or across multiple (behavioural syndrome) behaviours has key importance. State-dependence theory suggests that behaviour is ‘anchored’ to individual state (e.g. body condition, g...
Results of LMMs on activity and risk taking.
F statistics (numerator and denominator df in parentheses) and P values are shown. Significant effects are in bold font. SVL = snout to vent length; basking = basking time treatment; food = food treatment.

Results of GLMs on predictability of activity and risk taking in the pooled sample and in the different treatment groups.
First, we ran separate GLMs on the pooled sample with all possible interactions for activity predictability and risk-taking predictability. Second, based on the highest order significant interaction for the given behaviour, we r...
Change in body weight of adult male European green lizards (Lacerta viridis) between the low- and high food treatment groups.
Body weight change is represented by group specific means of individual slopes. 95% confidence intervals are shown.

While the number of studies reporting the presence of individual behavioral consistency (animal personality, behavioral syndrome) has boomed in the recent years, there is still much controversy about the proximate and ultimate mechanisms resulting in the phenomenon. For instance, direct environmental effects during ontogeny (phenotypic plasticity)...
The focus of evolutionary behavioural ecologists has recently
turned towards understanding the causes and consequences of behavioural consistency, manifesting either as animal personality (consistency in a single behaviour) or behavioural syndrome (consistency across more behaviours). Behavioural type (mean individual behaviour) has been linked to...
