population biology of allocreadium lobatum wallin, 1909 (digenea: allocreadiidae) in the creek chub, semotilus atromaculatus, mitchill (osteichthyes: cyprinadae), in a nebraska creek, usa.allocreadium lobatum wallin, 1909 has been reported in cyprinid species of freshwater fish in canada and in the united states. the population biology of a. lobatum in the host semotilus atromaculatus mitchill was studied from may through december 1991, in a usa creek. overall prevalence (64%) and mean intensity (4.4 +/- 0.4) were greater than previously reported while abundance, reported for the first time, was 2.8 +/- 0.3. several trends in a. lobatum population biology as a function of s. atro ...200111313639
spatial heterogeneity in the parasite communities of creek chub (semotilus atromaculatus) in southeastern nebraska.the intestinal helminth communities of creek chub (semotilus atromaculatus) were studied in the streams of southeastern nebraska to characterize spatial variation, to determine whether drainages act as regional species pools, and to examine the spatial patterning of individual parasite species within and among drainages. creek chub were sampled in the summer of 2003 and the spring of 2004 at each of 12 sites distributed evenly among 3 drainages in the big nemaha river watershed. four intestinal ...200616729677
community structure and seasonal dynamics of dactylogyrus spp. (monogenea) on the fathead minnow (pimephales promelas ) from the salt valley watershed, lancaster county, nebraska.the gill monogene communities of pimephales promelas (fathead minnow) in 3 distinct sites on converging streams were investigated from 2004 to 2006 in 3 different seasons. thirty collections of p. promelas were made in southeastern nebraska along 3 converging tributaries: elk creek (40.88534°n, 96.83366°w), west oak creek (40.9082°n, 96.81432°w), and oak creek (40.91402°n, 96.770583°w), lancaster county, nebraska. in all, 103 p. promelas were collected from elk creek, 115 from west oak creek, an ...200919642810
