    Flora of the Erie Islands: A Review of Floristic, Ecological and Historical Research and Conservation Activities, 1976 – 2010
    (2010-04) Duncan, Thomas; Brohl, Lisa; Kartesz, John; Oldham, Michael J.; Stuckey, Ronald L.
    The purpose of this review is to survey the floristic, ecological and historical research about the Erie Islands and its flora since 1976 and to describe efforts to conserve Erie Island habitats. Island location records, surveys and multi-island inventories reveal that over 1,000 vascular plant taxa are known from the Erie Islands and new records continue to be found. Alvar habitats, rare globally, occur on the Erie Islands and are a focus of conservation efforts. Forest composition is primarily related to island elevation above lake level and moisture availability. Patterns of succession in abandoned vineyards and orchards are not the same due to differing agricultural practices prior to abandonment that favored different suites of invading species. Applying island biogeographic theory and methods to analyze the flora of the Erie Islands demonstrated that the indigenous flora on individual islands varies in relation to the size of an island in accordance with biogeographic theory whereas the non-indigenous flora on smaller islands is a constantly changing random subset of the non-indigenous flora of larger islands. Geological and palynological research about pre-settlement forests support the historic descriptions of these forests by early European settlers. Governmental and private efforts to preserve Erie Island habitats and the flora therein expanded significantly in the past 35 years. Efforts by the State of Ohio, the Province of Ontario, non-governmental organizations and island communities to acquire and conserve unique island habitats resulted in the preservation of important alvar, wetland and woodland habitat on large islands and the acquisition of Green Island, Middle Island and West Sister Island.

    The Effect Of Participation In A Stone Laboratory Workshop (A Place-Based Environmental Education Program) On Student Affect Toward Science
    (2010-04) Malinowski, Jennifer; Fortner, Rosanne W.
    This case study measures how participation in a one-and-one-half-day place-based environmental education program (the F.T. Stone Laboratory student workshop) influences the affect component of attitudes (otherwise defined as “feelings”) toward science among sixth grade students. Prior to and following a Stone Laboratory workshop, students were surveyed regarding how they felt about science. Across the entire sample (n=90) there was a small but consistent positive change in student response on the written survey, suggesting that participation in the Stone Lab workshop has a positive influence on general affect toward science in the short-term. Analysis by defined subscales was also conducted, highlighting significant positive change for students on the General Science Feelings and Value of Science subscales. The effect is strongest among male participants in this group.

    An Anomalous Breccia Associated with the Serpent Mound Impact Crater, Southern Ohio
    (2010-04) Milam, Keith A.; Hester, Adam; Malinski, Peter
    An anomalous carbonate breccia in the Serpent Mound impact crater in southwestern Ohio was examined and possible depositional/emplacement mechanisms were evaluated in an effort to determine its origin. This breccia was likely formed by sedimentary deposition and subsequent weathering during the Middle-Late Silurian prior to the Serpent Mound impact event. This origin is supported by the lateral extent of the breccia, the elevation range over which it is exposed, its spatial association with Middle-Upper Silurian strata, a mineral assemblage limited to dolomite, compositional homogeneity, and its similarity to Middle-Upper Silurian geologic units. Field observations, mineralogy, and geochemical analyses do not support emplacement by fault comminution, gravitational collapse of crater slopes, or ballistic/resurge deposition of ejecta.
