Mixing of Water in Streams: Big Walnut Creek and its Tributaries, Ohio
(1997-12) Petz, Timothy R.; Faure, Gunter
A graphical procedure for resolving three-component mixtures of water is demonstrated by using chemical analyses of Big Walnut Creek and two of its tributaries (Alum Creek and Blacklick Creek) near Columbus, OH. The concentrations of conservative cations (Na, Ca, Mg, and Sr) indicate that on 5 December 1992 Alum Creek contributed 46.6±0.6%, whereas Blacklick Creek added 28.2±2.0% of the water in Big Walnut Creek downstream of the confluence. The procedure can be used in laboratory exercises to provide rational explanations for variations in the chemical compositions of streams and to gain insight into the different types of water that may mix in a stream.
Lateral Zonation of Trees along a Small Ohio Stream
(1997-12) Vadas, Robert L., Jr.; Sanger, Jon E.
Riparian-vegetation patterns along a small stream in Ohio were examined with multivariate and graphical analyses. The study focused on elevational differences in larger tree species (>10 cm DBH = diameter at breast height) on a floodplain bench, floodplain slope, and upland terrace. The three habitat zones showed differences in floral assemblages related to the flooding tolerance of tree species, the floodplain bench showing ash-maple dominance and the other habitats yielding maple-beech-oak dominance. The floral differences were likely attributable to natural and human impacts, particularly stream flooding and possibly past logging. The results and a literature review suggest that hydrologic disturbances (for example, flooding) create predictable, parallel patterns in floral assemblages along a lateral (stream-edge to upland) gradient. Riparian assessments in the lateral dimension can provide information to predict the effects of anthropogenic instream-flow alterations on riparian ecosystems, including small tributaries.
Promise and Practice: The Dichotomous Nature of Partnership Between Parks and Recreation and Higher Education in Northeastern Ohio
(1997-12) Uhlik, Kim S.
A survey of 73 northeastern Ohio parks and recreation department directors confirmed what parks and recreation leaders have recognized as a national dilemma; despite strong support for the concept of partnership, 93% of local parks and recreation directors did not have current links with colleges and universities. Although respondents' positive reactions toward partnership were significantly related to the perceived likelihood of partnership creation (r = .5282,/? = .01), only slightly more than half believed that partnership formation was likely to very likely. Funding availability, while a concern of many directors, did not positively or significantly correlate with either reaction (r = -.0156, p = .01) or likelihood (r = -.0860,/? = .01). Further, given the low rate (7%) of extant partnerships, the proximity of parks and recreation departments to postsecondary institutions (mean = 4 institutions per department) did not promote partnership creation. The apparent disparity between partnership's perceived promise and actual practice suggests the influence of mediating factors inhibiting the potential collaborators' initiative to act. Systemic forces (such as institutional inertia), the lack of partnershipbuilding information and models, and insufficient or unclear motivational factors may play pivotal roles.
Fish Communities of the Vermilion River Watershed: Comparison of the Main Channel and Tributaries
(1997-12) Heithaus, Michael R.; Grame, Christopher
The Vermilion River watershed was the focus of a fish community survey from October 1995 through May 1996. Fish communities were sampled with a backpack electrofisher and a kick seine. A total of 8,005 individuals were collected representing 9 families, 49 species and at least 2 hybrids. Stoneroller minnows (Campostoma anomalum) were the most abundant species in the main channel followed by bluntnose minnows (Pimephales notatus), rainbow darters (Etheostoma caeruleum), then striped shiners (Notropis chryocephalus). Tributaries were dominated by creek chubs (Semotilis atromaculatus^, stoneroller minnows, and bluntnose minnows. Fish species richness was greater in the main channel than in tributaries. Also, there were greater proportions of insectivorous fishes and species intolerant and moderately intolerant to pollution in the main channel. Generalists and pollution tolerant species dominated the tributaries. This pattern illustrates the importance of considering data from these habitats separately when attempting to assess the quality of fish communities or develop management strategies.
