Reproducible study results

Content

This repository contains the results presented in the paper “Predicting coral trends and attributing drivers of change from local to broad spatial scales” by Vercelloni et al.

The files Appendix_A.html and Appendix_B.html correspond to the manuscript appendices. They can be reproduced by rendering the quarto documents located in the scripts/ directories.

Appendix_C.html can be also reproduced by rendering the quarto document located in Appendix_C folder.

Data tables

Monitoring and disturbance data are provided in the Appendix_A/data and Appendix_B/data folder, which contains these files:

• reef_data_aggregated.csv: observations of coral cover at data-tier locations. The table contains eight variables - Tier4 (marine ecoregion id),Tier5 (data-tier identifier), fYEAR (survey year), COUNT (count of coral cover), TOTAL (total point count), LONGITUDE (associated with Tier5 centroid), LATITUDE (associated with Tier5 centroid).
• covariates_full_tier5.RData: a shapefile containing disturbance information across all tiers. The table contains 22 variables with Tier5 (all-tier identifier), year, severity_dhw* (severity of heat stress and associated time lags), max_dhw* (maximum values of degree heating weeks for the survey year and associated time lags), severity_c* (severity of cyclone exposure and associated time lags), max_cyc* (maximum cyclone exposure for the survey year expressed as hours of exposure to cyclonic waves and associated time lags).
• tier5.sf.RData: a shapefile indicating Tier5 locations.
• tiers.lookup.RData: a lookup table linking Tier5 with Tier4 levels.
• reef_layer.sf.RData: a shapefile of the Tropical Coral Reefs of the World
