Diversidad faunística en el medio subterráneo volcánico, con especial énfasis en las Islas Canarias

The different types of habitable underground environments existing in volcanic terrains are listed, with special emphasis on the different types of mesocavern networks (mesovoid shallow substratum, scree, pyroclastic deposits) and macrocaverns (lava tubes, volcanic pits, emptied dikes). A table of cave richness in the islands of Macaronesia is presented, and the environmental parameters of volcanic caves are analyzed. The types of adaptations of the subterranean fauna are discussed, and data on the diversity of such fauna in the Canary Islands are provided, with taxonomic and biological comments on each of the arthropods orders included. A comparative analysis of the troglobiont and stygobiont diversity among the different islands of the archipelago is made
