- Title
Global sensitivity analysis for complex ecological models: a case study of riparian cottonwood population dynamics.
- Authors
Harper, Elizabeth B.; Stllla, John C.; Fremier, Alexander K.
- Abstract
The article presents a case study on the use of global sensitivity analysis (GSA) to model the population dynamics of Fremont cottonwood (Populus fremonti) on the banks of Sacramento River in California. It says that GSA, with classification and regression trees (CART) and Random Forest methods, shows variance in annual germination frequency, annual first-year survival frequency, and patch occupancy. It adds that this variance was caused by the interactions among several abiotic parameters.
