Figure 2. Number of modern analogs for predicted future bird communities across climate models and distribution-model algorithms.

Figure 2

“Analog” communities are those for which Bray-Curtis dissimilarity was less than an ROC-determined optimal threshold, based on a 60-group level of community aggregation. Predictions of future bird communities are based on: A, GFDL CM2.1, Scenario A2, 2038–2070, generalized additive models. B, GFDL CM2.1, Scenario A2, 2038–2070, maximum entropy models. C, NCAR CCSM3.0, Scenario A2, 2038–2069, generalized additive models. D, NCAR CCSM3.0, Scenario A2, 2038–2069, maximum entropy models.
