Potter Cove food web (Antarctica): details on trophic species and interactions.

This is the supplementary data of the article "Potter Cove food web: complexity, structure and function". We constructed the FW of Potter Cove ecosystem (25 de mayo/King George Is., Antarctica) based primarily upon information about species living in that system and their feeding habits from studies within the framework of an international research cooperation between Argentina and Germany initiated in 1994 and continued for more than 20 years. We collected the information on feeding links by a thorough literature search (> 500 papers and reports revised). To assemble the network we only considered trophic interactions confirmed by gut content studies and/or field observation.
