摘要

Anchialine caves house a vast variety of organisms that support complex ecological relationships among themselves and their environment. The following study was made in the anchialine karst cave El Aerolito, found on Cozumel Island, Quintana Roo, Mexico. It explores the relationship between wall microbial mats and the diet of Asterinides sp., an endemic stygobitic seastar. Wall microbial mats inside the cave were sampled and the stomach microbiome of Asterinides sp. was obtained through regurgitation. Asterinides sp. sampling was made through the Catcher Collection Chamber (CCC), an innovative technology for the exploration of these ecosystems. The obtained results suggest that microbial mats are part of the diet of Asterinides sp. The following results highlight the potential relevance of the microbial communities inside the trophic chain present in El Aerolito. Additionally, the methodology presented here provides a useful framework for future ecological research in El Aerolito cave.
