Risk-taking salamanders share less space with conspecifics
Boldness is a personality trait defined as the propensity of an animal to engage in risk-taking behaviours. Boldness is often associated with social ranking, dispersal, movement, and home range in many animal species. In this study we tested if boldness was correlated with individual spatial behaviour, in a population of the Cave Salamander Speleomantes strinatii living in a subterranean habitat. Boldness was measured in a controlled environment by means of an emerging from a shelter trial, while home ranges and distances moved over two years were obtained in the wild from a spatially explicit capture-mark-recapture study. We obtained data from 13 salamanders that were captured at least 5 times (mean 7.23; range 5-11). As expected, there was a highly significant and negative correlation between individual risk taking behaviour and home range overlap with conspecifics (rs = 0.84; p = 0.005). This pattern could be explained by differences in habitat physical quality or in its available resources, but more research is needed to better understand this behavioural pattern.
