Models simulating abrupt changes in the Chilika lagoon fishery, the Easter Island community, forest dieback and lake water quality

This deposit is in support of Willcock et al "Anthropocene ecosystems collapse sooner with faster, multiple and noisy drivers". It covers the following items: (i) A list of the files contained within this data deposit; (ii) How to access and download the specialist software required to view and simulate the system dynamics models (STELLA ‘isee Player’); (iii) How to run isee Player to simulate the models; (iv) How to access and download the standard statistical software ‘R’ to run the R scripts; (v) How to load ‘R’ and modify the standard R script to analyse a subset of the model runs. This file will also details the ‘required content’ (e.g. software versions), as specified in the ‘nr-software-policy.pdf’ document.

The full descriptions of each of the four system dynamics models used in this manuscript can be read in the following papers:
