This is the thirteenth annual report to FDER to satisfy the requirements set forth in Reclaimed Water and Effluent Limitations and Monitoring Requirements condition #10 of the Howard F. Curren WWTP operation permit FL0020940-001-DW1P.

The City of Tampa, Bay Study Group (BSG), has monitored the effects of sewage pollution abatement in Hillsborough Bay since 1976. During the mid 1980's, water quality improvements and evidence of minor seagrass revegetation in Hillsborough Bay prompted the BSG to initiate a seagrass study to compliment other programs assessing the environmental status of Hillsborough Bay.

Using Gis And Land Use Data To Select Candidate Reference Sites For Stream Bioassessment, John Robert Olson

Theses and Dissertations

GIS was used to select candidate reference sites in Georgia to characterize the reference condition by sub-ecoregion for a rapid bioassessment of streams statewide. Instead of relying on best professional judgment or previous knowledge of a limited number of sites, we performed an objective evaluation of cumulative impact on all catchments using land use data sets. These included road and impoundment data from DLGs and Multi-Resolution Land use Consortium data. Land use impairment was measured as percentages of forest, urban, pasture, row crops, and barren area for both the entire catchment and for 10, 40, and 130-m riparian buffers, road …

1080 Summary Information, Department Of Agriculture, Western Australia, Department Of Conservation And Land Management, Western Australia, Department Of Health, Western Australia

Biosecurity research reports

Fluoroacetate, the active ingredient of 1080, occurs naturally in toxic plants in Australia, South Africa, and South America. Manufactured I080 underpins most vertebrate pest control programs in Australia and New Zealand. Fluoroacetate occurs naturally in about 40 plant species in Australia with most of these plants restricted to the south-west of WA.

I080 was introduced to rabbit control programs in the early 1950s and therefore has a long history of proven effectiveness and safety in Australia. There have been few repo1ted problems associated with human safety, environmental persistence, bioaccumulation or impact on populations of non-target species.

In particular, I080 baits …

Simulation And Economic Study Of The Med-Tvc Units At Umm Al Nar Desalination Plant, Shaikh Omar Al-Habshi

Theses

A rigorous mathematical model has been used to develop a steady state simulation program MEDNAR to analyze the multi-effect thermal vapor compression desalination (MED-TVC) plant at Umm Al-Nar power and desalination plant. The effect of thermodynamic losses on the thermal performance ratio, the specific heat transfer area and the specific flow rate of the cooling water are taken into account. The losses contemplated are the boiling point elevation and the temperature depression corresponding to the pressure drop during the vapor condensation process. The MEDNAR also takes into consideration the variation in the physical properties of the seawater with temperature and …

Uncertainty Of Exploitation Estimates Made From Tag Returns, L.E. Miranda, R.E. Brock, Brian S. Dorr

United States Department of Agriculture Wildlife Services: Staff Publications

Over 6,000 crappies Pomoxis spp. were tagged in five water bodies to estimate exploitation rates by anglers. Exploitation rates were computed as the percentage of tags returned after adjustment for three sources of uncertainty: post-release mortality due to the tagging process, tag loss, and the reporting rate of tagged fish. Confidence intervals around exploitation rates were estimated by re-sampling from the probability distributions of tagging mortality, tag loss, and reporting rate. Estimates of exploitation rates ranged from 17% to 54% among the five study systems. Uncertainty around estimates of tagging mortality, tag loss, and reporting resulted in 90% confidence intervals …

The Drought Monitor, Mark D. Svoboda, Doug Lecomte, Mike Hayes, Richard Heim, Karin Gleason, Jim Angel, Brad Rippey, Rich Tinker, Mike Palecki, David Stooksbury, David Miskus, Scott Stephens

National Drought Mitigation Center: Faculty Publications

There is a need for improved drought monitoring and assessment methods in the United States. Drought is the most costly natural disaster [Federal Emergency Management Agancy (FEMA 1995; Wilhite 2000)], but it is often neglected by developers of assessment and forecast products. Drought is more nebulous than other disasters and does not lend itself to traditional assessments or forecast methods. Its relatively slow onset and the complexity of its impacts are reasons for the new assessment methodology. Improvements in drought monitoring and forecasting techniques will allow for better preparation, lead to better management practices, and reduce the vulnerability of society …

Fisheries Management Report No. 6 - Proceedings Of Marron Farming Open Day 2002, Greg B. Maguire

Fisheries Published Reports

The marron industry is of considerable importance to the Department of Fisheries, being one of the older aquaculture industries in Western Australia, and one that accounts for around half the aquaculture licence holders in the State. While it has not grown as quickly as many hoped in the past, in 2000/01, some 52.2 tonnes of marron were produced, worth $1.18 million at the farm gate.

It is regionally significant, particularly in the south-west, and depending on appropriate site selection, has considerable potential in other areas. Farms are distributed from near Geraldton to around Bremer Bay, with additional interest around Esperance. …

Fisheries Research Report No. 139 - A 12-Month Survey Of Recreational Fishing In The Gascoyne Bioregion Of Western Australia During 1998-99, Neil R. Sumner, P C. Williamson, B E. Malseed

Fisheries Research Reports

A 12-month creel survey of recreational boat-based and shore-based fishing in the Gascoyne bioregion of Western Australia was conducted between April 1998 and March 1999. During the survey 1,738 boat crews were interviewed at public boat ramps when they returned from their fishing trip. During patrols conducted along the coastline 695 groups of boat-based fishers and 1,060 groups of shore-based fishers were interviewed at fishing locations and camp sites.

The total annual recreational fishing effort for the Gascoyne bioregion was 243,000 fisher days (95%CI: 222,000 – 264,000). This comprised 113,000 fisher days by boats launched from public ramps, 53,000 fisher …

Development Of Diagnostic Approaches To Determine Sources Of Anthropogenic Stress Affecting Benthic Community Conditions In The Chesapeake Bay, Daniel M. Dauer, Michael F. Lane, Roberto J. Llansó

Benthic Applications

Benthic macrofauna are an important component of estuarine ecosystems. These organisms are a food source for higher trophic levels including fishes and crabs (Virnstein 1977, 1979; Holland et al. 1980; Dauer et al. 1982) and birds (Botton 1984; Quammen 1984). Benthic macrofauna affect both the physical and chemical properties of the sediment and the overlying water column (e.g., Rhoads and Young 1970; Rhoads 1973; Aller 1978, 1980), influence nutrient cycling (Rowe et al 1975; Zeiteschel 1980; Flint and Kamykowski 1984), and are capable of directly controlling phytoplankton biomass in the water column (Cleorn 1982; Officer et al 1982; Cohen et …

Nutria (Myocaster Coypus) In Louisiana, John Baroch, Mark Hafner, Tommy L. Brown, Jeff J. Mach, Richard M. Poché

Other Publications in Wildlife Management

Biology and Natural History of the Nutria, With Special Reference to Nutria in Louisiana
The nutria or coypu (Myocastor coypus) is a rodent native to South America that has been introduced almost worldwide since the early 1900’s, originally with the intent of fur farming in many cases. The nutria is a large (over 6 kg), semi-aquatic rodent with a voracious appetite and high reproductive potential. Nutria became established in the Louisiana wetlands in the 1930’s. The habitat proved to be ideal and populations exploded, reaching an estimated 20 million animals in less than 20 years. Trapping of nutria …

Pre-/Post-Knowledge Assessment Of An Earth Science Course For Elementary/Middle School Education Majors, David C. Gosselin, Joy L. Macklem-Hurst

School of Natural Resources: Faculty Publications

Many K-12 educators never experience active learning processes in their science courses that are part of their formal teacher preparation program because of the prevalence of the didactic teaching approach (lecture-read-answer) used in undergraduate science classrooms. From an educational perspective there are substantial benefits to experiencing the process of science through active learning strategies. A 16-week, one semester course entitled, “Earth Systems Science for Educators” has been designed at the University of Nebraska-Lincoln to use an active learning approach to improve student knowledge of basic Earth science concepts. To evaluate the extent to which their knowledge has improved, we developed …

Chromate Content Bias Versus Overspray Particle Size In Three Aircraft Primer Paints, Brian S. Rhodes

Theses and Dissertations

The United States Air Force relies on the corrosion inhibiting properties of chromate-containing primer paints to protect the aluminum skin of its aircraft. Hexavalent chromium (Cr⁶⁺) the ingredient responsible for the corrosion inhibiting characteristics of these primers is a known human carcinogen. The concentration of Cr⁶⁺ in different particle sizes of paint overspray is important to understand health implications to painters as well as filtration efficiency. Previous research indicates disproportionately less Cr⁶⁺ content in smaller particles collected in the overspray of solvent-based epoxy-polyamide paint primers (MIL-P-2377G). This research explores the possibility of a particle size bias …

An Anion Characterization Of A Constructed Wetland Used For Chlorinated Ethene Remediation, Bradley M. Bugg

Theses and Dissertations

Chlorinated ethenes physical properties as well as its ubiquitous state at DOD installations makes it a priority for innovative remediation efforts. Current techniques are expensive and time consuming to maintain. Constructed wetlands suggest an inexpensive and operational alternative to conventional technologies. Sub-surface flow wetlands provide the anaerobic zones necessary to reduce the recalcitrant chlorinated solvents prior to anaerobic or aerobic mineralization of its daughter products. A vertical flow cell to include sequential sedimentary layers of two hydric soil lifts and a mix of hydric soil and woody compost was the subject of this investigation. This study focused on the statistical …

Effect Of Roost Harassment On Cormorant Movements And Roosting In The Delta Region Of Mississippi, Mark E. Tobin, D. Tommy King, Brian S. Dorr, Scott J. Werner, David S. Reinhold

United States Department of Agriculture Wildlife Services: Staff Publications

Double-crested Cormorant (Phalacrocorax auritus) predation on Channel Catfish (Ictalurus punctatus) at commercial farms has been estimated to cost the Mississippi aquaculture industry approximately $5 million annually to replace consumed fingerlings. In 1997, catfish producers assumed responsibility for the dispersal of cormorants in night roosts in the eastern (interior) delta region of Mississippi, where catfish farms are concentrated. We documented movements of 50 cormorants marked with radio transmitters in the delta region from January through March 1997. We obtained 161 post-capture day locations and 176 post-capture night roost locations. Cormorants that were harassed at their night roost …

Habitat Management Approaches For Reducing Wildlife Use Of Airfields, Scott C. Barras, Thomas W. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose safety risks to aircraft and cost civil aviation over $390 million annually in the USA We reviewed published studies to summarize findings on habitat management techniques that have shown potential for wildlife strike reduction. Habitat components that may attract wildlife to airports include food, cover, water, and loafing areas. Although maintaining tall herbaceous vegetation on airfields may reduce the attractiveness of loafing and feeding sites for some species of birds such as gulls, this strategy may also increase cover and food resources for other hazardous species. Thus, optimum vegetation height management strategies require further research …
