Quantitatively Testing Predictions From Mechanistic Models: A Case Study for Island Biodiversity
A key test of an ecological model is whether it can quantitatively predict unseen aspects of the data not used in model fitting. Here, we test whether a model fitted only to island alpha diversity ca....
