Figure 2 . A conceptual diagram to explain that the predation risk hypothesis predicts that prey species will shrink activity during bright lunar illumination, denoted by orange color (lunar phobic), while the visual acuity hypothesis revels that prey species which have comparably good vision will increase activity during bright lunar illumination, represented by black color (lunar philic). Those species positively linked are denoted by green solid lines, and negative interactions are represented by blue dotted lines and blue circular are exhibited temporal activity patterns of leopard and prey for different four moon phase.
