Population Dynamics Of Distoichometra Bufonis (Cestoda: Nematotaeniidae) In Bufo Woodhousii, John J. Janovy Jr., Eugene Lee Hardin

John Janovy Publications

Prevalence, density, and variance/mean (= variance/density) ratios are reported for the cestode Distoichometra bufonis in 28 samples of the amphibian host, Bufo woodhousii, taken over a 3-yr period at two study sites on the South Platte River in Keith County, Nebraska, U.S.A. In addition, changes in host demography resulting from entry of newly metamorphosed toads into the terrestrial population are given. Prevalence and density (average number of worms per host, infected + noninfected) did not vary significantly either within or between sites and years unless newly metamorphosed toads were included in the analysis. Prevalence ranged from 70 to 100%, …
