| FIG. A1. Metabolically corrected biomass/100 ha of ocellated (Oc), bicolored (Bi), and spotted (Si), antbirds during census years both on Barro Colorado Island (BCI; filled symbols) and in Soberania National Park (SNP; open symbols). Census data in addition to those from this study were provided by: (Karr 1971, Willis 1974, Brawn et al. 1995, Robinson 2001, and Styrsky 2003). Estimates from this study for bicolored and ocellated antbirds show mean values with 95% confidence intervals. |
