Isotope Analysis in Ecology

Embryonated eggs of a trematode, presumably a heterophyid acquired by eating raw or inadequately cooked fish, were found in faecal concentrates from 13 (4%) of 324 Tokelauans. Positive samples originated from all three atolls of the New Zealand dependency, Atafu (08° 33′ 30″ S., 172° 30′ W.), Nukunono (09° 10′ S., 171° 50′ W.), and Fakaofo (09° 23′ S., 171° 14′ W.). Eleven of those concerned had never travelled beyond the Tokelau Group, making this the first center of autochthonous distomiasis known in the South Pacific.
