Small Mammal Population Dynamics And Community Structure In Three East Central Florida Communities, Mary Helen Keim
Small Mammal Population Dynamics And Community Structure In Three East Central Florida Communities, Mary Helen Keim
Retrospective Theses and Dissertations
Small mammal population dynamics and community structure were studied in three East Central Florida communities. The communities were compared as distinct stages of a sand pine scrub sere. The small mammals live-trapped with greatest frequency in this 3852 trap-night study were all cricetine rodents, Peromyscus polionotus niveiventris (beach mouse), Sigmodon hispidus littoralis (cotton rat), and Peromyscus gossypinus palmarius (cotton mouse). Population numbers, survival, body weights, hind foot lengths, age structure, sex ratios, reproductive cycles, and movements were discussed for each of three species mentioned. These data will serve as a baseline information for ecological monitoring studies associated with NASA Space …

The Reproductive Biology Of The Diamondback Terrapin, Malaclemys Terrapin Tequesta, Richard A. Seigel
The Reproductive Biology Of The Diamondback Terrapin, Malaclemys Terrapin Tequesta, Richard A. Seigel
Retrospective Theses and Dissertations
The reproductive biology of the Florida east coast terrapin, Malalemys terrapin tequesta was studied during 1977-1978 at the Merritt Island National Wildlife Refuge, Brevard County, Florida. Mating occurred in small canals and ditches during late march and April. Terrapins exhibited a poorly developed courtship behavior system: this was attributed to the relative isolation of the species due to its brackish water habitat. Nesting occurred on dike roads, rather than on sand dunes as reported for other races of Malaclemys. Air temperature was the most important factor controlling nesting activity. One to three clutches were laid each year. Malaclemys appeared to …
The Feasibility Of Detecting Poliovirus I In Water By Radioimmunoassay, Sheril K. Charba
The Feasibility Of Detecting Poliovirus I In Water By Radioimmunoassay, Sheril K. Charba
Retrospective Theses and Dissertations
A microtiter, solid-phase, indirect radioimmunoassay (RIA) has been developed and evaluated as a method for detecting poliovirus in water samples. Antiserum to poliovirus Type I, LSc2ab, was prepared in rabbits, and high titer, high avidity antiserum to rabbit globulins were radio- actively labeled with 125I by a modification of the Bolton-Hunter and chloramine T methods to increasing specific activities. The immunoreactivity of the labeled antibodies was assessed. After the preparation and standardization of all components of the assay. The optimum assay conditions were determined. These conditions included the method of coating the microtiter wells with antigen, the time and temperature …
The Biodegredation Of Vehicular Waste Petroleum In The Roadside Environment, Jesse W. Johnson
The Biodegredation Of Vehicular Waste Petroleum In The Roadside Environment, Jesse W. Johnson
Retrospective Theses and Dissertations
Bacteria from dry and wet roadside environments were examined for the ability to degrade hydrocarbons. The kinds and numbers of bacteria observed were similar to those reported in other petroleum contaminated environments. Surface soils (top 2.5 cm) immediately adjacent to the highway pavement and the sediments of shallow drainage ditches contained the highest concentrations of petroleum degrading bacteria (9.8 x 107 CFU/g). Concentration and species diversity of petroleum degrading bacteria decreased with distance from the highway pavement. Chromatographic analysis of highway stormwater runoff and the soil in close proximity to the highway indicated the presence of complex hydrocarbon mixtures of …
Factors Affecting The Hatching Success Of Loggerhead Sea Turtle Eggs (Caretta Caretta Caretta), M. Angela Mcgehee
Factors Affecting The Hatching Success Of Loggerhead Sea Turtle Eggs (Caretta Caretta Caretta), M. Angela Mcgehee
Retrospective Theses and Dissertations
Clutches of eggs wore collected from nesting loggerhead sea turtles (Caretta caretta caretta) on Merritt Island, Florida, during June - August 1977. Of these, 46 clutches were selected for experimentation to determine the extent to which certain factors affect hatching success. Twelve clutches were divided into subsamples which were incubated in sand maintained at 0, 25, 50, 75, and 100% moisture. Another twelve clutches were divided into subsamples and incubated in sand kept moist with the following percentages of seawater: 0 (distilled water), 25, 50, 75, and 100%; subsamples from four other clutches were subjected to the effects of one …
Zooplankton Of The St. Johns River Estuary, Frederick C. Tone
Zooplankton Of The St. Johns River Estuary, Frederick C. Tone
Retrospective Theses and Dissertations
Zooplankton populations in the St. Johns River Estuary ranged from 3,000/m3 to 20,000/m3 during monthly collections from September, 1973 to August, 1974. Acartia tonsa Dana was the dominant organism throughout the year, except for spring blooms of Balanus sp. nauplii in the lower estuary and summer occurrences of Eubosmin tubins in the upper estuary. With these two exceptions, species composition, and community structure were similar throughout the estuary, year round. A patchy distribution of the zooplankton caused high replicate sample variation which made it difficult to detect small population variations. Salinity appeared to have the greatest effect on the distribution …
The Population Dynamics And Distribution Of Corbicula Manilensis (Philippi) In A Spring-Fed Central Florida Stream, Peter K. Gottfried
The Population Dynamics And Distribution Of Corbicula Manilensis (Philippi) In A Spring-Fed Central Florida Stream, Peter K. Gottfried
Retrospective Theses and Dissertations
Asiatic clams (Corbicula manilensis Philippi) were sampled at twelve stations randomly located along a 16-km stretch of the Wekiva River, Florida, every three months fro August 1976 to June 1977. Clams were found at most stations. Their abundance ranged from 4 to 1210 per m2. Mean numbers of Corbicula were highest at stations where the bottom sediments were primarily sand and lowest at stations where the bottom sediments were silt and decomposing organic matter. A linear relationship between water temperature, water depth, current velocity, total alkalinity, and pH, and the abundance and distribution of Corbicula was not evident. Seasonally, the …
