Dataset for: Long-term human movement dynamics and the contemporary distribution of Casearia sylvestris in Southern Brazil

CSV file containing the analytical dataset used in the statistical analyses of Casearia sylvestris abundance and occurrence in southern Brazil. The dataset includes environmental, climatic, archaeological probability, movement-cost, and Indigenous Territory distance variables for 428 vegetation sampling units. Variable description Casearia – Number of Casearia sylvestris individuals recorded in each sampling unit (abundance). 1x0 – Presence (1) or absence (0) of Casearia sylvestris in each sampling unit. jes_prob – Modeled probability of past meridional-Jê occupation derived from archaeological distribution models. guarani_prob – Modeled probability of past Guarani occupation derived from archaeological distribution models. SOMA_probs – Sum of meridional-Jê and Guarani occupation probabilities. CS_JE – Movement cost surface value representing landscape resistance for meridional-Jê mobility. Lower values indicate lower movement cost. CS_GUA – Movement cost surface value representing landscape resistance for Guarani mobility. Lower values indicate lower movement cost. JE_DIST_CAMINHO – Distance to modeled meridional-Jê movement pathways. dist_cam_je – Distance to reconstructed meridional-Jê circulation routes. peral_devpad – Standard deviation of elevation within the sampling unit, representing local topographic heterogeneity. rios_1e2ord – Distance to first- and second-order streams. rios_3e4ord – Distance to third- and fourth-order streams. 5a8_dist – Distance to higher-order rivers (orders 5–8). dist_costa – Distance to the coastline. altitude – Elevation (m above sea level). dist_ti_km – Distance (km) to the nearest Indigenous Territory. ua_dentro_ti – Indicates whether the sampling unit is located inside an Indigenous Territory (1 = yes, 0 = no). fito – Phytogeographic region according to the FlorestaSC classification. 1k_300 – Distance to urban areas with populations between 300 and 1,000 inhabitants. 2_1k – Distance to urban areas with populations between 1,000 and 2,000 inhabitants. 3_2k – Distance to urban areas with populations between 2,000 and 3,000 inhabitants. 9_3k – Distance to urban areas with populations greater than 3,000 inhabitants. impac_hum – Human impact index. bio1–bio19 – Bioclimatic variables obtained from WorldClim. The dataset includes all variables evaluated during model selection. Not all variables were retained in the final abundance and occurrence models presented in the manuscript.
