Ecological Gradients Influencing Waterbird Communities in Black Water Lakes in the Anavilhanas Archipelago, Central Amazonia
Figure 3
Rarefaction curves for the survey data from Anavilhanas Archipelago, showing bird species richness in relation to (a) number of lakes surveyed (sampling effort) and (b) number of birds. Continuous lines are rarefaction curves; the hatched line depicts observed data.
