Fitting empirical models to simulated seedfall
The data in this file were used to determine the relative fit of alternative empirical models to simulated seedfall data in Monks, Monks & Tanentzap (In press. Resource limitation underlying multiple masting models makes mast seeding insensitive to future climate change. New Phytologist). The data were simulated using the model described in Monks et al. 1000 replicated of 72 different parameter combinations were simulated. Reference to equations below denotes equations in Monks et al. Each simulation generated 50 years of data. Hence the number of rows in the file is 72100050 (i.e 3 600 000)
