Title Rocky reef multi-trophic level fisheries model: Global sensitivity analysis
Downloaded 1 time
Description R script to run a global sensitivity analysis (GSA) of all 24 parameters in the rocky reef multi-trophic level fisheries model. This GSA uses random forest to quantify parameter importance to the modeled outcome (mean trophic level at equilibrium). It then uses classification and regression trees to determine specific breakpoints in parameter space which drive modeled outcome. We use a uniform distribution for each parameter to set up 4,000 parameter sets which we then simulate the model using. Other distributions can also be used (Gaussian provided very similar results).

Downloaded 1 time
Description R script to run simulations of the rocky reef multi-trophic level fisheries model now including a constant level of external recruitment into the small urchin compartment. We simulate the baseline time series as well as tests of hysteresis for: FL x FU, FL x sigma, and FU x sigma.

Title Rocky reef multi-trophic level fisheries model: baseline + harvest
Downloaded 1 time
Description R script to run simulations calculating lobster and urchin fishery harvest at each time step. We use these to estimate the fishery harvest level at maximum sustainable yield (F_msy) for lobsters at three levels of urchin harvest.
