Shellfish Aquaculture Suitability Within Baylor Grounds Of The Lower Rappahannock River, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

Should the Commonwealth of Virginia ever consider a regulated expansion of the aquaculture industry to public Baylor ground, timely information regarding the productivity of these grounds and the ability to support aquaculture would be highly desirable information. In this scenario, public bottom will be opened to private shellfish growers in the Commonwealth under what will likely be a tightly monitored regulation. The demise in productivity of natural oyster beds within Baylor Grounds is well known. However, there is no comprehensive resource that addresses whether Baylor Grounds would be suitable for aquaculture. This study uses Geographic Information Systems (GIS) to model …

Assessing And Modeling Mangrove Forest Dynamics Along The Temperate-Subtropical Ecotone In Eastern Florida, Susan Leitholf

Electronic Theses and Dissertations

Mangrove ecosystems are among the world's most endangered biomes; nearly one-half of the overall coverage is threatened by human activity, invasive species, and global climate change. Mangroves play an important ecosystem role through detrital production and by providing: fisheries and wildlife nursery habitat, shoreline protection, a sink for nutrients, carbon, and sediment. In addition to human activity, the Florida mangroves (Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle) are being threatened by the invasive Brazilian pepper (Schinus terebinthifolius). This study was performed along a 261 km stretch of the east coast of Florida from Sebastian Inlet to the northern extent of …

Auditing And Assessing Air Quality In Concentrated Feeding Operations, N. A. Cole, R. Todd, B. Auvermann, D. B. Parker

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The potential adverse effects of concentrated animal feeding operations (CAFO) on the environment are a growing concern. The air quality issues of most concern to CAFO vary but generally include ammonia, hydrogen sulfide, particulate matter, volatile organic compounds, greenhouse gases, and odors. Air pollutants may be regulated by federal and state laws or by nuisance complaints. The United States Environmental Protection Agency, and poultry, swine, and dairy industries recently agreed to the National Air Emissions Monitoring System to fund research on atmospheric emissions from production farms in the United States. Air quality regulations may be based on actual emissions, atmospheric …

Simulations With Elaborated Worked Example Modeling: Beneficial Effects On Schema Acquisition, Debra K. Meier, Karl J. Reinhard, David O. Carter, David W. Brooks

Department of Entomology: Faculty Publications

Worked examples have been effective in enhancing learning outcomes, especially with novice learners. Most of this research has been conducted in laboratory settings. This study examined the impact of embedding elaborated worked example modeling in a computer simulation practice activity on learning achievement among 39 undergraduate students within a classroom environment. The students from one introductory forensic science course were randomly assigned to one of two groups that worked through computer-based simulations containing worked example modeling conditions presented in varied order. The computer software administered the modeled simulations, prior knowledge test, pretest, posttests, and a second domain test. Findings from …
