From: Craig StockwellSubject: GRADUATE ASSISTANTSHIP AVAILABLE GRADUATE ASSISTANTSHIP AVAILABLE FOR RESEARCH ON WHITE SANDS PUPFISH A graduate student assistantship is available beginning the fall semester, 2000 at North Dakota State University. The successful candidate will conduct dissertation research on questions regarding the conservation ecology of the White Sands pupfish. Current work focuses on parasite-host interactions. Two populations of White Sands pupfish (Cyprinodon tularosa) occur in relatively saline habitats and consequently escape parasitism by digenetic trematodes. In contrast the other two populations occur in relatively fresh habitats and are heavily parasitized. Research will focus on the costs of parasitism by digenetic trematodes and will examine if population history influences parasite resistance. We will also investigate the response of fish to exotic parasites. Research will include laboratory research and field work in southern New Mexico. The assistantship is scheduled for a Ph.D. candidate (Masters required), however outstanding students may be considered for support in the Masters program. The assistantship begins June, 2000, but the start date may be negotiated for an outstanding candidate. The assistantship includes a full tuition waiver. The North Dakota State University Zoology Department has a strong emphasis in organismal zoology and is committed to training independent, imaginative and productive scientists and educators.
