Boldness correlates with the mating success, but not body size or sex, of yellow-spotted monitor lizards roaming the remote Oombulgurri floodplains of tropical Western Australia, ecologists report in the Ecological Society of America’s open access journal Ecosphere. But boldness has a cost: bold individuals expose themselves to much higher risk of being eaten by predators during the dangerous wet season. The researchers demonstrated quantifiable behavioral syndromes in the large lizards, with an intriguing relationship to the lizards’ seasonal hunting strategies.
