Spatial Variation in Bird Community Composition in Relation to Topographic Gradient and Forest Heterogeneity in a Central Amazonian Rainforest
Figure 4
(a) The influence of terrain inclination (elevation), (b) stream proximity, and (c) depth of forest floor leaf litter on bird community composition in the Reserva Florestal Adolpho Ducke, Manaus, Brazil. Qualitative data (species presence/absence for the 72 transects with mist-nets), which were subjected to ordination analyses (PCoA). Only the second PCoA-axes were used to construct the graphs, the ones showing statistical significance.
