Vascular Flora of the King Road Landfill in Northwest Ohio
(2007-12) Barnswell, Kristopher D.; Dwyer, Daryl F.
The vascular flora of the King Road Landfill (KRL), located in Sylvania, Ohio, was surveyed during the 2004 growing season to evaluate the development of the plant community and compare it with that of four mature woodlands typical of the native Oak Openings Region: floodplain, sand barren, oak savanna, and deciduous forest. All surveys were made using the U.S. Department of Agriculture’s Forest Inventory and Analysis method for phase two plots. Of the 153 plant species identified at the KRL, 60% were native. It was interesting to note that threatened and endangered species (e.g., Digitaria filiformis, Lupinus perennis, and Panicum lindheimeri) also were present. Comparative analysis revealed little similarity with the regional woodlands (Jaccard Index values < 0.5). Two primary factors may have been responsible: (1) 30 years of inactivity at the KRL were insufficient to attain a mature plant community. Indeed, late successional plant species were observed only in the landfill section that had been closed for the longest period of time. (2) The vegetation that surrounded and thus colonized the KRL was not similar to that of the regional woodlands (Jaccard Index values < 0.5). The results of this study were presented to the Ohio Environmental Protection Agency as part of a remedial option for the KRL, which includes creation of a nature preserve at the KRL and an opportunity to direct and study the long-term development of the maturing plant community.
The Effects of the Penry Wellfield (Delaware, Ohio) on Well-Water Quality
(2007-12) Mann, Keith O.
Water samples collected during three phases (Background, Pumping and Recovery) of a year-long study in Delaware County, Ohio, document groundwater quality and the effects of pumping up to 1,500 gpm from the City of Delaware’s Penry Wellfield on nearby well-water quality. Study-phase means of pH ranged from 6.84—6.99 and alkalinity means varied from 352—371 mg/L (as CaCO3), while specific conductance means exceeded 825μS/cm, disolved solids means exceeded 499 mg/L, hardness means exceeded 525 mg/L (as CaCO3), and iron means exceeded 2.45 mg/L. The turbidity medians for all study phases exceeded 0.75 NTU. No significant links, either in a predictive or general sense, between water-quality parameters and well depth, flow path, time, or combinations of these variables existed. The average pH of the Background Phase (6.99) differed significantly ( =0.05) from both the Pumping Phase (6.89) and the Recovery Phase (6.84) and the mean alkalinity concentration of the Pumping Phase (352 mg/L) differed significantly from the Background Phase (371 mg/L). The Pumping Phase experienced significantly larger dissolved solids concentrations (639 mg/L) than either the Background Phase (499 mg/L) or the Recovery Phase (521 mg/L); however, no significant differences were detected with respect to specific conductance, hardness, or iron concentrations. The turbidity median of the Background Phase (0.75 NTU) differed significantly from both the Pumping Phase (1.48 NTU) and the Recovery Phase (1.36 NTU) medians and turbidity values routinely (52%) exceeded 1.0 NTU. Finally, pumping did not cause H2S concentrations to rise above detectable levels.
Age-Dependent Vulnerability of the Striatal Mitochondrial to 3-Nitropropionic Acid
(2007-12) Nasr, Payman; Delorme, Thierry
From studies to date, there is considerable evidence suggesting that energy impairment may be a common biochemical mechanism underlying the etiology of a number of metabolic disorders. Metabolic disorders are the result of an abnormal metabolic function at the cellular level, which can be inherited due to a genetic mutation, or acquired as a result of a series of multigenic diseases such as diabetes. The impact of metabolic disorders such as diabetes is growing in the state of Ohio. The statistics from the Diabetes Association of Greater Cleveland show a very high rate of diabetic complications in Ohio, where over 800,000 people have diabetes- about 1/16 of the population in Ohio. To study the effect of metabolic disorder at a cellular level, we have utilized 3-nitropropionic acid (3NP) to induce energy impairment and assess the metabolic response of two age groups to such stress. 3NP has long been known to inhibit succinate dehydrogenase activity of the Krebs cycle and the respiratory chain in mitochondria. Systemic administration of 3NP results in a selective striatal lesion in rodent and primate models. 3NP-induced toxicity has previously been demonstrated to be age-dependent, in which the older animals are more vulnerable to 3NP toxicity than the younger animals. The present study was designed to investigate whether 3NP treatment demonstrates variable potency in the isolated mitochondria from the striatum of younger (two-month-old) versus older (10-month-old) Sprague-Dawley rats.
Vegetation Release Eight Years After Removal of Lonicera maackii in West-Central Ohio
(2007-12) Runkle, James R.; DiSalvo, Angie; Graham-Gibson, Yolanda; Dorning, Monica
Lonicera maackii is thought to inhibit growth of herbaceous vegetation and woody seedlings. To determine the extent of this inhibition, in April 1996, Lonicera was removed from ten 30 x 30 m areas within Sugarcreek Reserve. Paired 20 x 20 m plots were established, one of each pair in the removal area and one adjacent to that area. These plots varied in history and topographic position. Twenty 1-m2 small plots were established in each large plot and sampled for herbaceous vegetation (by species and cover class) and woody seedlings (species and number). Sampling was done summer 1996 and spring 1997. Nine of the paired plots were resampled summer 2003 and spring 2004. Few differences were found between control and treated plots the first year after Lonicera removal. Significant differences between control and treated plots were found seven to eight years after treatment in both spring and summer: treated plots had higher species richness, higher cover, and higher tree seedling densities. These results indicate that Lonicera removal can enhance ground layer species diversity and cover after a lag period of at least one year.
