Brief Note: A Gravity Reference Station at Wright State University
(1995-09) Rittenger, Paul; Wolfe, Paul J.
An absolute gravity reference station has been established in a publicly accessible area of the Wright State University campus, in Fairborn, OH. A new station was needed for the area because the previous stations were either found to be faulty or were in a restricted access area of Wright-Patterson Air Force Base. The gravity value is 980 074.51 +/-0.2 milligals.
Brief Note: New Records of the Flora of Lorain County, Ohio
(1995-09) Walters, Timothy L.
A floral survey of the Lorain County Metro Parks and non-park areas was conducted from mid-March to mid-September 1993 to aid in the development of management plans. A total of 734 species was documented for the county. Of these, 687 of the 1,229 (55.9%) historically recorded species were vouchered, along with 47 new species not previously recorded. The new species are presented in this report. This brings the number of floral species of the county to at least 1,276 species.
Brief Note: Discovery of the Federally Endangered Freshwater Mussel, Epioblasma obliquata obliquata (Rafinesque, 1820) (Unionidae), in Ohio
(1995-09) Hoggarth, Michael A.; Rice, Daniel L.; Lee, Diana M.
Discovery of the purple catspaw, Epioblasma obliquata obliquata, in Killbuck Creek, Coshocton County, OH, is reported. This subspecies of unionid mollusc was thought to have been extirpated from the state in the mid to late 1800s and was known only from two nonreproductive populations in Kentucky and Tennessee. The mussel was thought to be on the verge of extinction. Fifteen living and 23 dead specimens of this subspecies were collected in September 1994 from Killbuck Creek. This is the largest known population of this rare subspecies and it is the only known population to currently support breeding individuals. It is threatened by soil erosion resulting from agricultural land-use practices such as clearing of the stream banks for farm fields and cattle grazing and by muskrat predation.
Recent Records of the Endangered Western Banded Killifish, Fundulus diaphanus menona, in the Portage River Basin, Ohio
(1995-09) Poly, William J.; Miltner, Robert J.
Within the past decade, the western banded killifish, Fundulus diaphanus menona, has been collected on several occasions in the Portage River basin, from which it was previously considered extirpated. In 1994 while conducting fish community assessments using electrofishing, a total of 13 F. d. menona were collected at three localities within the Portage River basin. Additional recent collections of F. d. menona have been made by Ohio Department of Natural Resources personnel. The recent records have been plotted along with historic records in order to update the status and distribution of F. d. menona in Ohio. The well-being of Ohio F. d. menona populations may depend upon several factors. Habitat disturbance has been and continues to be detrimental to F. d. menona and other fish species in the Portage River basin. The recent invasion or population increase of blackstripe topminnow, Fundulus notatus, may affect the F. d. menona population through competition or hybridization. Intergradation between F. d. menona and the eastern banded killifish, F. d. diaphanus, may occur if the latter continues its westward range expansion in the Lake Erie basin.
Brief Note: Perching Orientation Affects Number of Feeding Attempts and Seed Consumption by the American Goldfinch (Carduelis tristis)
(1995-09) Horn, David Joseph
In the mid 1800s, J. J. Audubon illustrated American Goldfinches (Carduelis tristis} feeding upside-down to obtain seed from thistles. The influence of feeding orientation on the number of feeding attempts and seed consumption by the American Goldfinch was investigated in the present study. Six rightside up feeders and six upside-down feeders were filled with thistle seed and put on 1.83 m poles. The number of feeding attempts and seed consumption by goldfinches were recorded. Results from one-way ANOVA tests show that goldfinches attempted to feed right-side up more often and ate greater quantities of thistle while feeding in an upright position. The agility of the American Goldfinch may be one reason that this species will readily feed both right-side up or upside-down. However, for the birdwatcher interested in attracting the American Goldfinch, a feeder where birds eat in an upright position is more effective.
Brief Note: Food Habits of the Coyote in the Vizcaíno Desert, México
(1995-09) Sanabria, Bernardo; Ortega-Rubio, Alfredo; Arguelles-Méndez, Cerafina
We studied the food habits of the coyote (Cams latrans) through stomach contents analysis, in the Vizcaino Desert, Baja California Sur, Mexico, from January to March 1984. Thirty stomachs were analyzed, and their contents identified. Rodents and plants are the most frequent foods consumed. Taking into account the mass of food items ingested, rodents (JDipodomys and Thomomys} were the main prey items consumed. There was no evidence of domestic livestock ingestion.
Distribution and Persistence of American Chestnut Sprouts, Castanea dentata (Marsh.) Borkh., in Northeastern Ohio Woodlands
(1995-09) Schwadron, Patricia A.
Sprouts and stumps of American chestnut, Castanea dentata [Marsh.] Borkh., were mapped from data collected at three forested sites of varying size and historical background in Cuyahoga County of northeast Ohio to compare the species' present distribution with that of its historical distribution in the mentioned areas. Sprouts were absent from one site despite a dense population of remnant chestnut stumps. Distribution of sprouts within the two remaining sites was sparse except for localized high concentrations. In addition to the aggregated pattern, sprout distribution was somewhat shifted from chestnut stump distribution indicating that such stumps are not the direct sources of regenerative tissue, but were the likely seed sources for younger, active root systems presently generating sprouts. Data collected to assess sprout location in relation to canopy changes indicated a continued association of American chestnut with white oak, Quercus alba, and red oak, Quercus rubra. Variations in sprout distribution are related to past land use and the subsequent stage of development of each site. The absence of sprouts from the old growth forest is attributed to competitive exclusion by shade tolerant species—mainly sugar maple, Acer saccbarum, and American beech, Fagus grandifolia. Although comparisons of sprouting rates versus death rates over a three year period indicated a 30% increase in the number of chestnut stems giving the appearance of a growing population, succession toward beech-maple forests was evident at all three sites as is the case in many forested areas of this region.
Subfossils of the Boreal Mosses Calliergon trifarium and Meesia triquetra in an Indiana Peatland
(1995-09) Swinehart, Anthony L.
Analysis of peat cores extracted from Tamarack Bog, section 7, Noble Township, Noble County, IN, revealed the first recorded subfossils of the boreal mosses Calliergon trifarium (Web. & Mohr.) Kindb. and Meesia triquetra (Richt.) Aongstr. from the state of Indiana. The paleo-environment was characterized as a mineral-rich fen. Local extirpation was attributed to natural acidification. The regional distribution of these two species, since glaciation, has receded northward to the northern lake states. Both species are now extirpated in Indiana.
Teacher Opinions Concerning Science Projects and Science Fairs
(1995-09) Grote, Michael G.
A 20-question Likert scale and a brief questionnaire concerning science projects and science fairs were sent to approximately 600 randomly-selected high school science department chairpersons in Ohio. Slightly over 30% of the sample returned the survey. Respondents preferred having students do projects as individuals, although working in pairs was nearly as acceptable. Respondents strongly supported preservice training in structuring independent science research projects for students. A large majority of respondents felt that doing science research projects taught lessons that could not be duplicated by classroom instruction. A slight majority agreed that science projects are valuable, but that judging them in a science fair setting is counterproductive. At the same time, respondents said science fairs promote enthusiasm about science, give students experience in communication skills, and give students the opportunity to interact with other students interested in science. Respondents also indicated that science fairs were more appropriate at the junior high level than at the high school level, although a majority indicated that independent research projects are a more appropriate activity for high school students.
