The plasmodium of Physarum polycephalum is a unicellular and multinuclear giant amoeba. The plasmodium has the ability to sense and adapt to many kinds of environmental stimuli, and its optimization behavior in closed spaces has been analyzed extensively. However, few studies have tested the behavior of the plasmodium in an open spaces, despite the biological importance of the adaptability of biological entities in such conditions. Accordingly, we established an experimental setup with a very large and strictly homogeneous substrate and observed the long-term exploratory behavior of the plasmodium. As a result, we found that the movement of the plasmodium was consistent with a Lévy-walk, but with anisotropic bias.

This study aimed to investigate the role of risk perception in two models: a) as a mediator between personal norms and pro-environmental attitudes of farm managers and b) as a mediator of trust in the purchase intention of consumers.

In cannibalistic species, conspecifics can be both predators and prey. As a result, conspecifics present a unique conflict at the intersection of predation, competition and nutritional resources in these species. To better understand how individuals respond to the complex information of conspecific chemical cues, we studied aggressive and cannibalistic tadpoles of the dyeing poison frog, .

Trait aggression is often separated into two functional dimensions: reactive and proactive tendencies. Reactive aggression is the tendency to engage in emotionally driven aggressive responses to perceived provocation, whereas proactive aggression is the tendency to engage in premeditated aggressive behaviors in the service of goal attainment. To date, the majority of empirical investigations examining these interrelated constructs have done so using cross-sectional data that have important limitations (e.
