Figure 2. Colony abundance vs. guano stain area.

(A) Colony abundance (and 95^th percentile confidence intervals; as reported by [7] as a function of the area identified as guano in the Landsat-7 survey (black circles  =  continental Antarctica, orange squares  =  Antarctic Peninsula), with best-fitting Poisson regression model (and associated 95^th percentile prediction envelop; gray-shaded envelop  =  continental Antarctica, orange-shaded envelop  =  Antarctic Peninsula). (B) Zoomed in portion shown as blue box in Panel A.
