Fig. 3. Species accumulation curve (triangles) and estimated amphibian species richness (Chao 2, squares; and Jack-knife 1, circles) of the Taï National Park and surrounding agroforestry system. The mean values of 500 random runs of the daily species lists are given. A daily species list comprised the presence/absence records collected during seven hours of sampling (four hours during daylight, and three hours during night) on one plot by two people for a total of 14 person-hours.
