Snail Assemblage for the Federally Threatened Anguispira picta
University of Tennessee
Department of Earth and Planetary Sciences
Land snails are a highly diverse and ecologically important group. However, they are very poorly studied and comparatively little is known about their distribution and conservation status. Among the few land snail species known to be at risk is the federally threatened Painted Snake Coiled Forest Snail or Painted Tigersnail, Anguispira picta (Clapp), which is endemic to the southern Cumberland Plateau, Franklin County, TN. The objective of this study was to identify the community of land snails that co-occur with A. picta. Of the 1,063 specimens collected, 927 were identified, belonging to 28 species in 17 genera. The most common genera, Anguispira, comprised 30% of collections; while Anguispira cumberlandiana, and three other species, represent new county records. This study adds to the ecology of A. pica, which continues to be threatened by habitat loss and other disturbances in its limited range.
Mackenzie Hodges earned her B.S. in Environmental Studies, concentrating in Wildlife Ecology from the University of Tennessee in 2012. During that period she began working with Dr. Michael McKinney on Upper Cumberland land snail communities. She is now a Masters Candidate in Geology, studying urban snail diversity in Chattanooga, Nashville, and Knoxville.
Underground Storage of Carbon Dioxide: Introduction and Field Demonstration Examples
Advanced Resources International
Carbon Dioxide capture and storage (CCS) technologies have the potential to reduce CO2 emissions from new and existing coal- and gas-fired power plants and large industrial sources. After separation and compression of CO2 from the source it is transported to an injection site(s). This presentation will introduce the concept of underground injection and geologic storage of the CO2 into deep underground rock formations. Experiences with a U.S. Department of Energy-supported demonstration of CO2 capture, transport and storage, the Anthropogenic Test, will be shared.
David Riestenberg is a Project Manager with Advanced Resources International, Inc. He has over ten years of experience in petroleum and energy technology research and consulting. He is currently a technical manager for the Anthropogenic Test CO2 storage demonstration where he has been responsible the geologic assessment, monitoring and permitting efforts. In addition, Mr. Riestenberg has led multiple CO2 storage geologic and economic assessments for state and federal governments, large point-source CO2 emitters including power companies, and pore space holders.
