Figure 5. Study plot, representing an area of reproduction of Leptodactylus labyrinthicus, in which foam nests and calling sites were mapped in the 2002–3 reproductive season. (Above) General aspect of the area; (below) schematic map showing the point of placement of the egg clutches (1–14) and the more frequently used calling sites (A, E and I).
