Fig. 1From: Foraging dispersion of Ryukyu flying-foxes and relationships with fig abundance in East-Asian subtropical island forestsAccumulated proportions of relative abundance (○; RA), relative frequency of occurrence (□; FO), and relative importance (●; RI) values of tree species as number of species identified increased at the forest sites assessed in Iriomote Island, Japan. Curtis and McIntosh’s [43] use of the arithmetic mean of RA and FO was adopted to obtain an estimate of the relative importanceBack to article page
