Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
During continuing studies of avian helminths at Palmer Station, Antarctica (Hoberg 1983) trematodes were found as parasites only of charadriiform birds. Digeneans were not represented in extensive collections (including several thousand specimens of helminths) from spheniscids, procellariids, and phalacrocoracids.
The pattern of distribution of trematodes in marine birds in Antarctica is influenced by the availability of suitable intermediate hosts (mollusca) and the foraging behavior of potential final hosts. Littoral environments near Palmer are structurally simple and of low diversity due to ice scouring. The limpet, Nacella polaris, is the dominant intertidal invertebrate and one of the few molluscs that …
