AB: Recent advances in artificial feeding techniques have increased the numbers and reliability of fingerling production of muskellunge Esox masquinongy in Iowa. Most of the muskellunge fingerlings produced in Iowa since 1984 were raised on dry pelleted feed. We compared the survival of pellet-reared fingerlings with traditional minnow-reared fingerlings stocked into Spirit and West Okoboji lakes in northwest Iowa. Beginning in 1991, all muskellunge fingerlings were marked with freeze brands to differentiate the type and year that fingerlings were stocked. Adult muskellunge were caught each spring with 360-ft, 2.5-in-bar-mesh gill nets. All muskellunge caught were examined for brands, individually marked with visual implant tags, and released into the same lake as captured. Abundance and survival of stocked fingerlings to year-classes were estimated from recaptures of branded and individually marked muskellunge. In most years none of the pellet-reared fingerlings survived. The poor survival of these fish was most likely due to a combination of poor health, poor color (camouflage barring was muted and virtually nonexistent), and small size (6-9 in total length, TL). Minnow-reared muskellunge fingerlings were much larger (10-13 in TL), displayed strong camouflage barring and no apparent nutritional problems, and survived much better than pellet-reared fish. Minnow-fed fingerlings stocked in the spring survived much better than those stocked in the fall. One spring stocking of only 572 fish more than doubled the muskellunge population in West Okoboji Lake. Such success with stocking muskellunge in the spring could drastically change stocking strategies in Iowa; fewer fish may need to be stocked, and management objectives could be met without annual stockings.

AB: The diatom concentration of a uniform lake sediment sample was estimated in 15 laboratories. Whilst 21 of 35 estimates were between 13 and 19 X 107 valves g-1, values ranged from 8.2 X 106 to 2.0 X 109 valves g-1. However, counts from replicate sediment digestions, replicate slide preparations from a single digested slurry, and multiple counts from an individual slide all yielded internally consistent results, with acceptably low coefficients of variation (+- 4.5-6.3%). Without greater efforts towards harmonization, for example by calibrating techniques to a standard of known concentration, reported diatom concentration values, as well as derived data such as diatom accumulation rates, are not directly comparable between most laboratories. This sharply contrasts the strong reproducibility of diatom relative frequency data. A calibration exercise, using the Eucalyptus pollen spike technique to estimate a known concentration of Lycopodium spores, demonstrates that this method performs best when approximately equal proportions of microfossils and introduced markers are counted.

AB: Seven stations, established in 1968 to sample Cladocera, were sampled again, using the same methods, in 1988. Seven species [Daphnia longiremis, Pseudosida bidentada, Latanopsis occidentalis, Moina micrura, Macrothrix laticornis, Kurzia latissima, Pleuroxus laevis], all of them in low abundance, new are records for Lake West Okoboji. In 1988, there was little difference 1) in the ranking of the stations relative to abundance of cladocerans, 2) the distribution and abundance of the species by habitat-type, 3) the seasonality of the predominant species in the specific habitats, 4) the temporal patterns of the number of species and total cladoceran abundance in the specific habitats, compared to 1968. On the average there were more species but lower cladoceran abundance in the three bay habitats during the summer of 1988. The biggest differences between the two years was the high degree of predominance in the limnetic by Daphnia pulicaria in 1988 compared to 1968. This difference is attributed to apparent low productivity in 1988 associated with a dry year with little runoff, early stratification of the lake and other evidence of a halt to the rapid eutrophication evident in 1968.

AB: Secchi disk transparencies, chlorophyll a concentrations, and total phosphorus concentrations were studied in Lake West Okoboji, Iowa, in the summers of 1971-73 and 1987-89. The average summer Secchi disk transparencies varied from a low of 2.5 to a high of 5.5 m during the study. The variations in the transparency of Lake West Okoboji from year to year seem to be related to climatic factors such as the amounts of spring precipitation in the watershed and probably reflect changes in the annual inputs of plant nutrients. There is some indication that climatic conditions that cause the period of deep mixing to extend into the early summer lead to a greater Secchi disk transparency, but more data are needed to confirm this hypothesis. Other than these fluctuations related to climatic variables, there is no indication of any systematic changes in water quality in the period from the early 1970s to the late 1980s.

AB: Standardization of body site for scale sampling would improve comparability of growth data among studies. Although some standardization has been achieved, reasons for choosing sites have rarely been documented. In our study, four scales were collected from each of several sites on yellow perch Perca flavescens from West Okoboji Lake and Clear Lake, Iowa [USA]. On the basis of the least variability in scale size and lowest frequency of regenerated scales, the site below the lateral line at the tip of the pectoral fin when the fin was pressed to the body was selected. Sex of fish and season of collection did not significantly affect the body-scale regression, intercept values for which ranged from 15 mm for scales from the caudal peduncle to 50 mm for scales from the most anterior site.

AB: A new species Stephanodiscus vestibulis is described from an eutrophic, hardwater habitat [canal connected to Lake West Okoboji, Iowa, USA] in western North America. Under the light microscope it resembles, and has perhaps been confused with, certain other small species of the genus. Structural features of the valve resolved by SEM, however, show that it is unique. The new species is particularly characterized by arch-like vestibules over the external openings of the marginal strutted processes. Other features include central and marginal strutted processes with three satellite pores, internally domed criba on the puncta and a single labiate process.

AB: Ultrasonic telemetry was used to study the movement and behavior of nine adult muskellunge, 69 to 101 cm in total length. Intensive fish tracking conducted from June to August 1978 produced 1178 contacts, the basis for summer home range determinations. Eight fish established summer home ranges by the time surface water temperatures rose above 17.degree. C in mid-June, and by early July all fish exhibited home range behavior. Individual summer home ranges were 39 to 443 ha (mean = 146 ha) in area as determined by the minimum convex polygon method, and 27 to 73 ha (mean = 63 ha) as estimated by the grid-square method. Six fish had home ranges comprised of two distinct activity centers, 2.0 to 3.5 km apart. Some home ranges spatially overlapped, but occurrences of two fish at a common location were rare. In autumn, six of eight surviving fish remained within or near their summer home ranges. Observations on these eight fish during spring and summer 1979 provided evidence of reproductive and nonreproductive homing behavior.

LA: ENGLISH
AB: The faunas and floras from the Dows Local Biota provide an opportunity to compare Holocene taxa without a cultural bias. The Dows Local Biota is located in a large depression on the back side (north) of the Altamont I Moraine complex within the Des Moines Lobe. The Dows Silt Fauna/Flora (= DSF; .apprx. 9380 .+-. 130 yr B.P.), 1 horizon of the Dows Local Biota, was collected for plant macrofossils, mollusks and micromammals. DSF terrestrial gastropods are upland mesic forest dwellers although 1 spp., Strobilops affinis, is characteristic of more xeric forests and may represent open woods. The aquatic gastropods reflect both permanent and periodic waters. DSF micromammals prefer an open, mesic, deciduous forest. The micromammal sympatry is restricted to a small area within the tension zone and deciduous forest belt of west-central Wisconsin. DSF plants are characteristic of upland forests, moist meadowlands of disturbed areas and aquatic habitats. The DSF plant sympatry is large but restricted to the conifer-hardwood and deciduous forests along the Great Lakes-New England regions. Quantitative climatic data for the combined DSF sympatries suggest that Dows (.apprx. 9380 yr B.P.) was cooler than at present, and is nearly identical to that achieved by pollen analyses at the Cherokee Sewer-Lake West Okoboji sites (.apprx. 9000 yr B.P.) in northwest Iowa. Basd on common habitat interpretations and sympatries, .apprx. 9380 yr B.P. north-central Iowa was cooler and moister than at present and was occupied by an open deciduous forest.

None of 341 bluegill (L. macrochirus) were infected. Lobate cysts (up to 3 mm diameter) adjacent to the gall bladder contained sporulating plasmodia and mature spore masses. Inflammatory responses in the infected pancreas included engorged blood vessels, endocrine cell nuclei pyknosis, leukocyte (mostly lymphocyte) infiltration, fibroblast proliferation, dark pigment deposition and fibrosis. Host reaction was most pronounced in pancreas containing unencapsulated spore aggregates. Spore variability and plasmodial structure are also described.

LA: ENGLISH
AB: Pollen and plant macrofossils preserved in lake sediment from Lake West Okoboji, Dickinson County, Iowa, indicate how the vegetation of that area changed during the late glacial and postglacial. A closed coniferous forest, dominated by spruce and larch trees, produced the Picea-Latrix pollen assemblage zone. Fir trees were a minor constituent of this forest; pine trees were probably absent. Black ash trees increased in abundance at Lake West Okoboji and 13,500 yr ago were an important constituent of the forest. The sediment accumulation rate and the pollen influx were low throughout this time. Birch and alder pollen peaked in abundance approximately 11,800 yr ago. Pollen influx increased rapidly as birch and alder replaced coniferous trees on the uplands. A deciduous forest, containing abundant oak and elm trees, replaced the birch-alder-coniferous forest. This forest inhabited northwestern Iowa from approximately 11,000-9000 yr B.P. Nonarboreal species became prevalent between approximately 9000 and 7700 yr B.P. as prairie began to replace deciduous forests on the uplands. Charred remains of Amorpha canescens and other upland species attest to the presence of prairie fires as an aid in establishing prairie and destroying the forest. The pollen influx declined. The warmest, driest part of the postglacial occurred in northwestern Iowa from approximately 7700-3200 yr ago. Lake level fell 9-10 m, and prairie extended to the edge of the lake. Wet-ground weeds inhabited areas near lake level which were alternately flooded, then dry. Pollen influx was approximately 100 grains/cm2 per yr during the driest time in this dry interval. Deciduous trees, particularly oaks, returned after approximately 3200 yr B.P. Prairie continued to occupy the uplands, but trees were more common in the low-lying wet areas. Settlement by Europeans in northwestern Iowa about 1865 is marked by an increase in weed pollen. Macrofossil deposition changed in 1910 in response to the stabilization of lake level.
