Fig. 4. Monthly distribution of Gymnorhamphichthys rondoni within the grid in the Yahuarcaca terra firme stream in Leticia, Amazonas. The continuous line represents the maximum stream width reached during high water months, and the dashed line the minimum stream width reached in low water months. a. to m. Each sketch represents a sampling month and each number represents the total number of G. rondoni individuals found during five to six days at each quadrant for that particular month.
