Subterranean spiders (Arachnida: Araneae) from the Western Italian Alps

A dataset with all the referenced distribution points of the species considered in the subterranean localities included in the the P.R.I.N. 2022 project “DEEPCHANGE” (2022MJSYF8), funded by the Ministry of Universities and Research (Italy). The dataset consists of a single table (saved as a tab-delimited .csv file) of 47 columns and 370 rows, each row representing a distinct subterranean site. The distribution of examined sites spans three regions (Piemonte, Valle d’Aosta, and Liguria) and 9 provinces (Alessandria, Aosta, Biella, Cuneo, Imperia, Torino, Verbano-Cusio-Ossola, Vercelli, Novara ), with elevations ranging from 105 to 2563 meters above sea level. The first 15 columns contain information on the characteristics of the subterranean habitats included in the database. The following 31 columns represent each spider species recorded in these subterranean sites.
