Plant Communities of Highland Heights Community Park, Cuyahoga County, Ohio
(2006-12) Jog, Suneeti K.; Johansen, Jeffrey R.; DeLong, Michael K.; Magee, Dennis
We have described the vegetation structure with respect to various community types of Highland Heights Community Park and adjoining territory. High values of Shannon’s Diversity Indexes and Floristic Quality Assessment Indexes indicate a superior quality, species-rich habitat with several high-fidelity species. Based on our research, which reveals that the study site is worthy of conservation and preservation, we suggest recommendations to the city of Highland Heights for park management and land use planning.
Status of the Organic Soils in the Scioto Marsh, Hardin County, Ohio
(2006-12) Spongberg, Alison L.; Moebius, Elaine
Scioto Marsh in Hardin County, OH, was a 16,000-acre wetland area that was drained in the mid-1800s by channelizing the Scioto River to create farmland. The resulting soils are characterized by a thick, organic-rich A horizon that contributed to the productivity of the area. During the subsequent years, wind erosion and farming practices depleted this layer, causing the underlying B horizon to become incorporated into the till zone in many areas. This paper is a re-evaluation of the status of the A horizon, in lieu of recommendations thirty years ago on how to preserve the remaining productivity. Our study re-sampled sites from previous studies from the 1930s and 1970s. Comparisons of A-horizon thickness, organic carbon content, and bulk density indicate that the A horizon depletion has greatly diminished from its earlier pace. This is most likely due to more conservation farming practices incorporated in recent years.
Bats of Ravenna Training and Logistics Site, Portage and Trumbull Counties, Ohio
(2006-12) Brack Jr., Virgil; Duffey, Jason A.
Six species of bats (n = 272) were caught at Ravenna Training and Logistics Site during summer 2004: 122 big brown bats (Eptesicus fuscus), 100 little brown myotis (Myotis lucifugus), 26 red bats (Lasiurus borealis), 19 northern myotis (Myotis septentrionalis), three hoary bats (Lasiurus cinereus), and two eastern pipistrelles (Pipistrellus subflavus). Catch was 9.7 bats/net site (SD = 10.2) and 2.4 bats/net night (SD = 2.6). No bats were captured at two net sites and only one bat was caught at one site; the largest captures were 33, 36, and 37 individuals. Five of six species were caught at two sites, 2.7 (SD = 1.4) species were caught per net site, and MacArthur’s diversity index was 2.88. Evidence of reproduction was obtained for all species. Chi-square tests indicated no difference in catch of males and reproductive females in any species or all species combined. Evidence was found of two maternity colonies each of big brown bats and little brown myotis. Capture of big brown bats (X2 = 53.738; P <0.001), little brown myotis (X2 = 21.900; P <0.001), and all species combined (X2 = 49.066; P <0.001) was greatest 1 – 2 hours after sunset. Capture of red bats did not vary over the night (X2 = 7.083; P <0.461). Rate of capture was not consistent over the season for big brown bats (X2 = 28.603; P <0.001) or all species combined (X2 = 10.969; P = 0.004), but was similar for little brown myotis (X2 = 4.184; P = 0.123).
Simplification of the Petz-Faure Graphic Procedure for Resolving Three Component Mixtures
(2006-12) Belliveau, Robert R.
A simplification of the Petz-Faure graphical procedure for resolving three component mixtures is presented which has the advantages of easier construction and more intuitive interpretation.
