E-mail: [email protected] ABSTRACT A nearly 800 specimen collection of stoneflies from Crane Hollow Nature Preserve (CNHP) in Hocking County, Ohio was examined. These samples revealed a rich assemblage of 41 species, 40% of the species known from the state and 57% of the species known to occur in the lower Scioto River drainage. Species represented by the greatest abundance coincided well with those that were represented by the greatest number of sampling events. Of seven similar studies CHNP had substantially higher richness than all but Powdermill Preserve of southwestern Pennsylvania with 51 species. Assemblages varied greatly such that the average Jaccard dissimilarity between locations was 76%. Additional species are predicted for the CHNP. The value of aggregating literature and specimen data for comparative analyses is discussed as a way to place results of current biomonitoring and ecological studies into historical context.

January 2011 SECTION 4: LOCAL MITIGATION PROGRAM COORDINATION Section 4: Local Mitigation Program Coordination 314 State of Ohio Enhanced Hazard Mitigation Plan Rev. January 2011 4.1 LOCAL CAPABILITY ASSESSMENT OVERVIEW The preparation of Local Hazard Mitigation Plans (LHMPs) is a precondition for receipt of Hazard Mitigation Assistance grant project funds under the Disaster Mitigation Act of 2000 (DMA 2000) which also requires that states examine LHMPs as part of their SHMP process. FEMA has established mitigation planning requirements for local jurisdictions to meet, among other things, to demonstrate that proposed mitigation actions are based on a sound planning process that accounts for the inherent risk and capabilities of the individual communities. The Ohio EMA Mitigation Branch administers the LHMP Program for the state. The Mitigation Branch supports and assists local governments in the development and update of LHMPs. In 2002 and 2003, significant amounts of federal and state PDM funds were provided to develop LHMPs. For the time period spanning from the 2005 plan to the 2008 update, the main planning emphasis of the Mitigation Branch has been to get LHMPs reviewed, adopted, and FEMA approved. From 2008 to 2011, the emphasis shifted to tracking LHMP progress and effectiveness in a quantitative way, and integrating plan information more significantly into the state plan. The focus during 2011-2013 will be populating the State Hazard Analysis, Resource and Planning Portal (SHARPP, see Appendix J) with local plan information that will enhance mitigation planning efforts statewide. Currently, Ohio has a very good LHMP participation rate.

For the first time on the south of the Russian Far East, in small cool spring- like streams of the Low Amur River Basin, viviparity or live-bearing reproduction of stone- flies Capnia khingana (Plecoptera: Capniidae) was recorded. Apparently, the development of nymphs in eggs takes more than two months. Mature embryos were found throughout the abdomen, thorax, and head of C. khingana females, their number varied from 178 to 124. The first-instar nymphs hatched inside female body and exiting under the genital plate had head capsule with apparent eyespots, thorax, abdomen, legs, cerci and antennae. The lengths of the firs-instar nymphs varied from 910.33 to 920.35 μm, and the width of the head capsule, from 161.85 to 171.13 μm. Key words: stoneflies, viviparity, oviparity, first instar nymphs, streams, Russian Far East. В. А. Тесленко, Н. М. Яворская.

Extant species of these three genera are found in Eastern Asia and in the Nearctic region. It is very probably that the genera must have been widely spread across the northern hemisphere in the Cretaceous period, before Europe was an archipelago in Eocene. The current state of knowledge about the seventeen Plecoptera species of Baltic amber is shortly presented. Due to discovered homonymies, the following nomenclatural corrections are proposed: Leuctra fusca Pictet, 1856 in Leuctra electrofusca Caruso & Wichard, 2010 and Nemoura affinis Berendt, 1856 in Nemoura electroaffinis Caruso & Wichard, 2010.

Adults were present at all times of the year. Species number varied from an autumnal low of 2 to a spring peak of 13. Adults of most species were present for less than 3 months, but Malenka depressa adults were present year‐round. Hesperoperla hoguei was the only strictly autumnal‐emerging species. The report of Suwallia dubia from Irish Gulch Creek represents a new California record. The stonefly faunas of Irish Gulch Creek (low coastal) and Sagehen Creek (high Sierra Nevada) were compared. Both creeks had similar numbers of species, but the species composition differed greatly, reflecting dissimilar environments (elevation, water temperature, thermal accumulation, and discharge). Irish Gulch Creek had uniform warmer temperatures; Sagehen Creek had variable colder temperatures. Peak emergence at Irish Gulch Creek occurred 2 months earlier than at Sagehen Creek. Keywords: Plecoptera, seasonal flight period, biodiversity, thermal stability, North Coast bioregion INTRODUCTION we studied these aspects for a small stream on the As might be expected from its varied topography, north coast of California.

  • Outline of Ohio Project Paper: Economic Development
    Capturing the Emerging Market for Climate-Friendly Technologies: Opportunities for Ohio Executive Summary Increasing certainty that humans are changing the earth’s climate through emissions of greenhouse gases is creating a new market for climate-friendly products and services. As states and nations begin to address climate change by regulating greenhouse gas emissions and encouraging the use of clean energy, demand is growing for technologies such as wind power, biofuels, and cleaner coal power plants. Ohio’s manufacturing and agriculture sectors are already providing some of these solutions, and the state’s economy stands to benefit as a supplier of the technologies and strategies to tackle climate change. This paper briefly describes the factors driving the growing demand for climate-friendly technologies, some of the key existing companies, organizations, and resources in Ohio, and the potential for Ohio to become a leading supplier of climate solutions. These solutions include a new generation of lower-emitting coal technologies, components for wind turbines, and the feedstocks and facilities to produce biofuels. The paper concludes with recommendations for how Ohio can capitalize on these emerging opportunities. These recommendations include focusing and coordinating state funding of climate technology programs, promoting the development of climate-related industry clusters, and exploring export opportunities to states and countries with existing carbon constraints. Introduction The U.S. National Academy of Sciences, and the science academies of the other G8 nations and Brazil, China, and India have concluded that the global climate is warming in large part as the result of emissions of carbon dioxide and other greenhouse gases (GHG) from human activities, mainly the burning of coal and oil.

The rather close proximity of Sagehen Creek to the actual meeting site (less than 100 m away) surely encouraged collecting of stoneflies. Sagehen Creek Field Station is located on the eastern slope of the northern Sierra Nevada Mountains of California, approximately 32 km north of Lake Tahoe. The Field Station occupies 183 ha. Sagehen Creek itself extends about 13 km from the headwater on Carpenter Ridge, east of the Sierra Crest to Stampede Reservoir on the Little Truckee River. The stream is fed by springs, fens, and other wetlands. The Sagehen Basin spans a significant precipitation gradient resulting in variation of stream flow.
