Ecological Gradients Influencing Waterbird Communities in Black Water Lakes in the Anavilhanas Archipelago, Central Amazonia

Figure 5

Seasonal changes in aquatic bird community composition (represented by score values of NMDS-axes, see Section 2 for more explanations). Bird community composition differed significantly between high-water periods (a = July 2007; b = July 2008) and low-water periods (c = November-December 2007; d = November-December 2009).
