Ecological Role of the Clam Jukesena foveolata (Bivalve, Cyamiidae) Inferred by Digenean Parasites in Subantarctic Waters

Original language description

Bivalves serve as the first intermediate hosts in the life cycles of some digeneans, but little is known about their larval stages along the southwestern Atlantic coast. These larvae may provide valuable insights into the ecological role of mollusks in parasite life cycles and marine food webs. This study offers a morphological, histological, and molecular (ITS2, 28S rDNA) description of the larval stages of three digenean species parasitizing the bivalve Jukesena foveolata in the Beagle Channel, Tierra del Fuego Province, Argentina. Sporocysts containing cercariae of a monorchiid species were found infecting the gonads and digestive glands (p = 2%), while metacercariae were encysted in the foot (p = 7%). Additionally, metacercariae of Renicola sp. (Renicolidae) were located between the tubules of the digestive gland (p = 2%), and metacercariae of Bartolius sp. (Gymnophallidae) were found in the extrapallial space (between the mantle and the valve, p = 13.5%), where they elicited a histopathological reaction with the secretion of a calcareous, igloo-shaped coating. The monorchiid larvae are described here for the first time in this bivalve, with fish as their definitive hosts. Metacercariae of Renicola sp. and Bartolius sp., both of which use coastal birds as definitive hosts, have been previously recorded in other mollusks from the Argentine coast. This study contributes to our understanding of the life cycles of digeneans from the southwestern Atlantic coast and the role of bivalve hosts in marine food webs.
