Brief Note: Comparative Morphology of the First-Stage Larvae of Two Species of Philometra (Nematoda: Philometridae) and One Species of Camallanus (Nematoda: Camallanidae) From Lake Erie Fishes Kelly, Rosemarie; Crites, John L.; Mergo, John C., Jr. Previous descriptions of larval philometrids and camallanids are based on observation from light microscopy. First-stage larvae of Camallanus oxycephalus, Philometra cylindracea, and Philometra sp. were examined by electron microscopy to determine whether differences seen in adult structure also occur in the larvae, allowing for identification of larval stages in the intermediate and definitive hosts. Similarities in larval structure supported some speculation as to the possible evolutionary link between these genera and their corresponding families.

Brief Note Distribution of Polygonum amphibium L. (Polygonaceae) in Ohio Hobbs, Clinton H. The water smartweeds are now considered one species, Polygonum amphibium sensu lato, represented in the Ohio flora by two varieties. One, var. stipulaceum, occurs mainly in the glaciated portion of Ohio; the other, var. emersum and also the intermediates between these two varieties, have an apparent random distribution in the state.

Purple Loosestrife (Lythrum salicaria) in Ohio's Lake Erie Marshes Balogh, Gregory R.; Bookhout, Theodore A. Purple loosestrife {Lythrum salicaria) is an exotic plant from Eurasia that has displaced more than 50% of the plant biomass in some wetland communities in the U.S. Its dense stands provide poor waterfowl and muskrat {Ondatra zibethicus) habitat. True-color 35-mm photographs (slides) taken at 1,500 m were used to map the distribution of purple loosestrife in Erie, Lucas, Ottawa, and Sandusky Counties, where most of the purple loosestrife in Ohio occurs. We identified 213 stands (0.4-60.2 ha in size) that comprised 1,287 ha of purple loosestrife. Stands were associated with areas that have been inundated because of high Lake Erie water levels since 1975. Within the study area, only those marshes that undergo annual treatment of glyphosate or are cultivated contain no purple loosestrife.

Annual Production of Creek Chub and Southern Redbelly Dace in a Small Woodland Stream Storck, Ted W.; Momot, Walter T. The annual production of the creek chub, Semotilus atromaculatus, and southern redbelly dace, Phoxinus erytbrogaster, was measured in a small headwater stream in southeastern Ohio. Creek chub annual production was 13.60 g • m~2 per yr, and P/B was 1.16. Dace annual production was 2.77 g • m~2 and P/B was 1.82. Even though the stream was acidic (pH 6.3) and infertile, fish production compared favorably with that of small alkaline streams. Considerable production within allochthonous food chains probably overrides the effects of low in-stream fertility.

Field Studies: Hardy Road Landfill and Industrial Excess Landfill, A Superfund Site Jackson, Jim L.; Bauder, James R.; Hardy, James; Kennedy, Mark S. The North Central Section of the Geological Society of America met in Akron, April, 1988. Hardy Road Landfill, Akron, Ohio, and Industrial Excess Landfill, Uniontown, Ohio were the foci of a pre-meeting field trip. At Hardy Road, geologic conditions contributed to off-site methane migration in 1984, resulting in destruction by fire of a private dwelling. Gas migration is now controlled by an active gas collection system. Sand and gravels deposited during multiple glacial events are underlain by lacustrine silts and clays. Lacustrine deposits and hydrology of the site are expected to control leachate. The glacial deposits are up to 150 m thick in the buried valley beneath the site.

Establishment of a Prairie on a Borrow-Pit Site at the Bergamo-Mt. St. John Nature Preserve in Greene County, Ohio Conover, Denis G.; Geiger, Donald R. During the spring of 1986, development of a prairie was begun on a site at the Bergamo-Mt. St. John Nature Preserve located in Greene County, Ohio. A major objective of the project was to reclaim a sand and gravel borrow-pit. Prairie was chosen for reclamation of this area because prairie vegetation was present in the immediate area and that type of community is well-suited to the extremes in moisture conditions on the site. The prairie is intended to provide a habitat for some species being displaced by human disturbance and to provide a specific plant community within the preserve. To establish grasses, seeds obtained from Western sources were planted in April of 1986 by hydroseeding on the graded site. Just prior to this, seeds of several forbs obtained from Western sources were broadcast over the area. Subsequently, seeds of grasses and forbs collected locally were broadcast. For species more difficult to establish, plants were propagated in soil-filled plastic-film cylinders. These, and other plants collected locally from disturbed sites, were transplanted into holes prepared with a soil auger. After three seasons of growth, approximately 36 species of Ohio prairie indicator plant species, along with a number of species of animals, have become established on the site despite the severe drought of 1988.

The Urban Heat Island at Toledo, Ohio Schmidlin, Thomas W. Thirty-one years of daily maximum and minimum temperatures at a rural site and a roof-top urban site were examined to determine the magnitude and seasonal variability of the urban heat island. Mean annual temperature was 2.0°C warmer at the urban site with the greatest urban-rural temperature difference occurring during the summer and the smallest difference during the spring. The urban heat island was more evident in daily minimum temperatures than in daily maxima. The number of days over 32°C (90°F) was more than doubled by the urban heat island and the number of freezing days was reduced by 16%. The freeze-free season was lengthened approximately 24 days by the urban warming, heating degree days were reduced by 10%, and cooling degree days were increased by 70%.
