Occurrence, Density, And Distribution Of The Larvae Of Three Commercially Important Crab Species In The Florida Current Off The Southeast Coast Of Florida, U.S., Gabriela L. Wisniewski

HCNSO Student Theses and Dissertations

Knowledge of the temporal and spatial distribution and density of the larvae of Florida‘s commercially important crab species, the blue crab, Callinectes sapidus, the golden crab, Chaceon fenneri, and the stone crab, Menippe mercenaria in the nearshore and offshore waters of Florida‘s southeast coast is minimal. Such data, however, can be crucial to our understanding of the population dynamics of these vital fishery species. To obtain baseline data of the occurrence and distribution of these species‘ larvae in the Florida Current, densities were obtained from zooplankton tows from an E-W transect northeast of Port Everglades, Ft. Lauderdale, Florida along …

Marine Bioinvasions And Climate Change, James T. Carlton, Sandra C. Lindstrom, Celia M. Smith, Jennifer E. Smith

National Invasive Species Council

BACKGROUND

Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals …

Realistic Vertical Atmospheric Profiles And Effects From Limited Surface Observations, Dane P. Ranney

Theses and Dissertations

The ability to accurately describe the atmospheric conditions around us is not only important to the Air Force, but to anyone involved in signal propagation. The programs currently utilized to describe the atmosphere take into account a variety of measures. The LEEDR (Laser Environmental Effects Definition and Reference) program in particular, allows the user to select a location, aerosol and molecular effects model, numerous cloud and precipitation events, as well as other features. Even with the control that the user has, the output that the program provides can vary from actual conditions on a day to day basis. This is …

Atmospheric Airglow Fluctuations Due To A Tsunami‐Driven Gravity Wave Disturbance, Michael P. Hickey Ph.D., G. Schubert, R. L. Walterscheid

Publications

A spectral full‐wave model is used to study the upward propagation of a gravity wave disturbance and its effect on atmospheric nightglow emissions. Gravity waves are generated by a surface displacement that mimics a tsunami having a maximum amplitude of 0.5 m, a characteristic horizontal wavelength of 400 km, and a horizontal phase speed of 200 m/s. The gravity wave disturbance can reach F region altitudes before significant viscous dissipation occurs. The response of the OH Meinel nightglow in the mesopause region (∼87 km altitude) produces relative brightness fluctuations, which are ∼1% of the mean for overhead viewing. The wave …

The June–July deployment was preceded by one week of flights over California (ARCTAS-CARB) focused on (1) improving state emission inventories for greenhouse gases and aerosols, (2) providing observations to test and improve models …

Abundance And Ecological Significance Of The Clam Rangia Cuneata (Sowerby, 1831) In The Upper Barataria Estuary (Louisiana, Usa), Wai Hing Wong, Nancy N. Rabalais, R. Eugene Turner

Faculty Publications

We proposed that Rangia cuneata (Sowerby, 1831) is an important estuarine bivalve with ecological significance in three coastal lakes in Barataria Bay, Gulf of Mexico—Lake Cataouatche, Lake Salvador and Lac des Allemands. Our goals were to determine the abundance and distribution of Rangia in these lakes and to measure clearance times to elucidate its potential impacts on phytoplankton communities. The estimated average densities of R. cuneata in Lake Cataouatche, Lake Salvador, and Lac des Allemands were 63, 157, and 107 individuals m−2, respectively, which is 30% lower than that observed in nearby Lake Pontchartrain. The size of clams in Lake …

Urban Heat Island Expansion In The Greater Las Vegas Metropolitan Area, Alex Remar

Earth and Soil Sciences

The growth of human settlements into vast urban metropolitan areas is often accompanied by relatively higher temperatures in comparison with surrounding rural countrysides, a phenomenon known as the “urban heat island effect.” The city of Las Vegas has been selected as an examination of this trend because of its unprecedented urban growth in the last 50 years, which has been mapped by satellite imagery for several decades. Studying the growth of Las Vegas’ relatively new heat island can provide valuable insight into the causes and magnitude of all urban heat islands in general.

In this investigation, a series of temperature …

Water Quality Outreach And Education Strategies For Northwest Arkansas And Regional Watersheds, Katie Teague, John Pennington

Arkansas Water Resources Center Technical Reports

Stakeholders impact water quality and have a responsibility to protect, maintain, and improve water quality throughout northwest Arkansas and watersheds everywhere. But unless the roles of responsibility and stewardship among all stakeholders is communicated clearly and repetitively, there will be little progress made towards maintaining and improving water quality, while lawsuits, blame, and inaction will persist. Thus, the overall goal of water quality education and outreach is to improve the ability of stakeholders to take care of their watershed by teaching them what actions are or are not beneficial for water quality protection, maintenance, or improvements. Specific outreach and education …

Water Quality And Watershed Conditions In The Upper Illinois River Watershed, Brian Haggard, Andrew Sharpley, Leslie Massey

Arkansas Water Resources Center Technical Reports

The Illinois River and its tributaries have many uses that have been designated by the Arkansas Department of Environmental Quality including fisheries, aquatic life, primary contact waters, secondary contact waters, drinking water supply, and agricultural and industrial water supply, and water quality affects whether these uses can be supported. Since water quality can be quite complex, many types of measurements can be used as water quality indicators; some common water quality measurements include pH, dissolved oxygen concentration, and conductivity. More complicated measurements include determining nutrients, sediment and bacteria in the water, as well as assessing the aquatic life—aquatic insects, fish, …
