DISTINCT EVOLUTIONARY LINEAGES OF SCHISTOCEPHALUS PARASITES INFECTING CO-OCCURRING SCULPIN AND STICKLEBACK FISHES IN ALASKA

Distinct evolutionary lineages of Schistocephalus parasites infecting co-occurring sculpin and stickleback fishes in Alaska

Sculpins (coastrange and slimy) and sticklebacks (ninespine and threespine) are widely distributed fishes cohabiting 2 south-central Alaskan lakes (Aleknagik and Iliamna), and all these species are parasitized by cryptic diphyllobothriidean cestodes in the genus Schistocephalus.The goal of this investigation was to test for host-specific parasitic
