portalDS

Overview

The goal of portalDS is to apply “dynamic stability” (Ushio et al. 2018) to the long-term rodent time series at Portal, to test whether this indicator of whole-ecosystem change predicts or lines up with abrupt community shifts.

Project Organization

This project is set up as an R package that implements functions for computing “dynamic stability”, mostly following Ben Marwick’s rrtools setup:

• The maizuru-dynamic-stability vignette reproduces the Maizuru Bay analysis from Ushio et al. 2018 as an example.
• The analysis folder contains R scripts and objects for the Portal dynamic stability analysis.
• The data, output, and figures folders contain data, results, and figures for both the Portal and the Maizuru Bay analysis.
