Data of Kouvari et al., 2021 - Humans and climate as possible drivers of the morphology and function of the mandible of Suncus etruscus in Corsica
Description
Data and R files for manuscript Kouvari et al., 2021 titled "Humans and climate as possible drivers of the morphology and function of the mandible of Suncus etruscus in Corsica" Highlights - Mandible shape changed rapidly over the short period of time (14-19th century AD). - This led to changes in the mechanical potential of the principal masticatory muscle, the temporalis. - The temporalis’s negative correlation with the masseter, as well as their link with the anthropisation index suggest diet shifts linked to human activity - The integration of the body and ramus is not an indicator of environmental changes. Specimen photographs are only available upon request, due to their massive file size. Data folders: - The landmarks_morpho_raw folder contains the raw landmark coordinates of the specimens. These were produced using the "tpsdig2" software (Rohlf, 2010). - The landmarks_morpho_total folder contains the landmark coordinates of the specimens for each fragment type, including specimens for other more complete fragment types. - The size_and_mp folder contains centroid size and mechanical potential data files. - The specimen_info folder contains the specimen information per fragment type (layer, D for right and G for left side mandible, and specimen number). R files have a title describing what they do and they are in the order of execution.

Steps to reproduce
Landmarks and semilandmarks were positioned with the "tpsdig2" software (Rohlf, 2010) on the specimen 2D photographs (available only upon request, because of massive file size). R files are numbered in order of execution. The analyses were performed using the latest versions of R, RStudio, using mainly the "morpho" (Schlager, 2017) and "geomorph" (Adams et al., 2017) R packages at the time (in 2018). Important updates might have taken place and parts of the scripts might nor perform as they did then. Please show some understanding that the scripts were written when the first author was in their early career stage (MSc) and they are far from perfect. The process is described in the main manuscript too, so it can be reproduced using a far better and optimized script. For any questions, please do contact the main (and corresponding) author and they will do the best they can to help. Figures for the manuscript were made in Illustrator CC.
