The performance of 2 nonparametric estimators of species richness, the bootstrap (S(B)) and kth-order jackknife (S(Jk)), are compared using simulated parasite communities. The parameters of the simulation match those of an earlier comparison that fav

In response to confusion regarding the taxonomy of halipegines inhabiting North American amphibians, the reproductive structures of the hemiurid Halipegus occidualis are described from adult worms reared from cercariae shed by Helisoma anceps from Ch

The transmission dynamics of the trematode Halipegus occidualis in its definitive host, Rana clamitans, have been examined over a 5-yr period in a North Carolina pond. The breeding season of green frogs coincides with the period of worm recruitment,

Interactions between metacercariae of Halipegus occidualis and ostracod second intermediate hosts (Cypridopsis sp.) were examined over 5 wk using female ostracods exposed to 4 cercariocysts each and maintained in isolation. Control ostracods were sub

The independent effects of host age and size on parasite abundance are examined in yellow perch from Garner Lake in east-central Alberta. Older, larger perch tend to have more species of parasites combined with larger parasite infrapopulations. Sexua

The temporal and spatial dynamics of the recruitment of Halipegus occidualis by the green frog, Rana clamitans, suggest that infections are acquired through predation on odonates, which become infected by feeding on ostracods. Discrepancies in the li
