These data files and analysis scripts were used in the meta-analysis of hunter-gatherer ecology in the Late Pleistocene and early Holocene published in Quaternary Science Reviews. The full reference is: 

Barton, C.M., Aura Tortosa, J.E., Garcia Puchol, O., Riel-Salvatore, J.G., Gauthier, N., Vadillo Conessa, M., Pothier Bouchard, G., 2017. Risk and resilience in the late glacial: a case study from the western Mediterranean. Quaternary Science Reviews In press 2017.

See the above paper and supplemental information for the many sources of the archaeological data compiled here. 

Data are provided in CSV and RData (*.rda) formats. R Markdown scripts will reproduce all analyses except for GIS maps and calculations of contemporaneous paleocoastlines. 

To reproduce analyses reported in the Barton et al QSR paper, expand R_scripts.zip and rdata_files.zip into the same folder. Open the *.rmd scripts in RStudio (https://www.rstudio.com), and run the scripts. After loading the data files (initial chunk in the *.rmd script), any chunk in the script should be runnable. The csv files can also be imported into R and used by the scripts. 

Ice core data are derived from data sets accompanying the following 2 papers:

Rasmussen, S.O., Bigler, M., Blockley, S.P., Blunier, T., Buchardt, S.L., Clausen, H.B., Cvijanovic, I., Dahl-Jensen, D., Johnsen, S.J., Fischer, H., Gkinis, V., Guillevic, M., Hoek, W.Z., Lowe, J.J., Pedro, J.B., Popp, T., Seierstad, I.K., Steffensen, J.P., Svensson, A.M., Vallelonga, P., Vinther, B.M., Walker, M.J.C., Wheatley, J.J., Winstrup, M., 2014. A stratigraphic framework for abrupt climatic changes during the Last Glacial period based on three synchronized Greenland ice-core records: refining and extending the INTIMATE event stratigraphy. Quaternary Science Reviews 106, 14-28.

Seierstad, I.K., Abbott, P.M., Bigler, M., Blunier, T., Bourne, A.J., Brook, E., Buchardt, S.L., Buizert, C., Clausen, H.B., Cook, E., Dahl-Jensen, D., Davies, S.M., Guillevic, M., Johnsen, S.J., Pedersen, D.S., Popp, T.J., Rasmussen, S.O., Severinghaus, J.P., Svensson, A., Vinther, B.M., 2014. Consistently dated records from the Greenland GRIP, GISP2 and NGRIP ice cores for the past 104 ka reveal regional millennial-scale δ18O gradients with possible Heinrich event imprint. Quaternary Science Reviews 106, 29-46.
