From: A global consistent positive effect of urban green area size on bird richness
The performance of 20 species-area relationship models fitted to 37 urban green area datasets. Performance was measured in three ways: a the proportion of studies for which a model provided the best fit; b the proportion of studies for which a given model provided a satisfactory fit (generality); and c the average AICc weight for datasets that fitted satisfactorily a given model (efficiency). See Table 1 for model names
