Self-organization in the dynamics of huddling behavior in Octodon degus in two contrasting seasons (Springer, 2015)In small mammals, huddling appears as an efficient response to low temperature with important consequences in energy saving, which in turn affect individual fitness. It has been proposed that this behavior is a self-organized ...
