A Determination Of Phylogeny And Hybridization History Within Clematis L. (Ranunculaceae) Using Actin And Nitrate Reductase Intron Sequences, Kimberly Fearn Do
A Determination Of Phylogeny And Hybridization History Within Clematis L. (Ranunculaceae) Using Actin And Nitrate Reductase Intron Sequences, Kimberly Fearn Do
USF Tampa Graduate Theses and Dissertations
The phylogeny of Clematis, section Viorna, was characterized in this study using molecular data. Two nuclear introns were sequenced for a variety of taxa: actin and nitrate reductase. Actin intron sequence data yielded very little phylogenetic information. Some basal clades were resolved, but there were very few well supported relationships between species of the Viorna section in both the neighbor joining and maximum parsimony analyses. Nitrate reductase intron sequence data was slightly more variable. The number of well supported relationships in both the neighbor joining and maximum parsimony analyses for nitrate reductase was greater, but still not sufficient …

Design, operation, and closure practices for Class I municipal solid waste (MSW) landfills are based on RCRA Subtitle D requirements for control of leachates and gases generated during the life of the landfill. Because leachate is generated as a result of water percolating through the landfill and waste consolidation, it contains dissolved and suspended materials that reflect the characteristics of the material it contacts. Over the past two decades significant changes have occurred in the characteristics of the waste streams that are disposed in landfills. In addition, many Florida municipalities have implemented Waste-to-Energy (WTE) systems. The WTE ash is either …
The Influence Of Habitat Variation On Demography Of Blue Jays (Cyanociita Cristata) In South-Central Florida, Keith Allen Tarvin
The Influence Of Habitat Variation On Demography Of Blue Jays (Cyanociita Cristata) In South-Central Florida, Keith Allen Tarvin
USF Tampa Graduate Theses and Dissertations
Vertebrate populations rarely are homogeneous. Instead they exist as arrays of demographically variable subpopulations that are linked through dispersal. Variation in habitat quality is a major cause of demographic variability among subpopulations, but few studies have examined habitat-specific demography empirically. Here I present a detailed field study o f habitat-specific demography in Blue Jays (Cyanocitta cristata) that occupied a habitat mosaic landscape in south-central Florida. By measuring habitat-specific demographic parameters, including density, reproductive output, survival, and dispersal, I tested for the existence of population sources and sinks associated with different habitats, and the applicability ofa series ofhabitat selection models …

Transmission electron microscopy was used to determine how immunogold labeling of PKC-alpha or -beta is modulated by the antitumor drug IFN (HuIFN alpha-2b) in the cytoplasm, membrane structures, and nucleus of rapidly dividing and confluent human glioma U-373 cells. Results showed that except for nuclear localization, there were no specific cytoplasmic organelles that PKC-alpha or -beta translocated to following HuIFN alpha-2b treatment. Electron micrographs of PKC-beta in proliferating cells depicted 1.34-fold more PKC-beta in the nucleus than in the cytoplasm and a 1-min HuIFN alpha-2b (500 units/ml) treatment transiently increased PKC-beta immunoreactivity in the cytoplasm (1.95-fold) and nucleus (1.97-fold). In …
What Controls Tropical Reef Fish Populations: Recruitment Or Benthic Mortality? An Example In The Caribbean Reef Fish Haemulon Flavolineatum, M. J. Shulman, John C. Ogden
What Controls Tropical Reef Fish Populations: Recruitment Or Benthic Mortality? An Example In The Caribbean Reef Fish Haemulon Flavolineatum, M. J. Shulman, John C. Ogden

Recruitment from a planktonic larval stage has been proposed to be an important factor in limiting populations of marine organisms, particularly tropical reef fishes. We monitored recruitment and population densities of juvenile size classes In French grunt Haemulon flavolineatum (Haemulidae) from October 1978 through December 1980 In a portion of Tague Bay, St. Croix, U. S. Virgin Islands. Within our study area, 95 % of new recruits settled onto the sand and seagrass lagoon floor and within a few weeks migrated to nearby reefs; the remaining 5'10 settled directly onto reef structures. Mean annual recruitment rate was 1.8 recruits per …

Herbivory Effects On Thalassia Testudinum Leaf Growth And Nitrogen Content, J. C. Zieman, R. L. Iverson, John C. Ogden
Herbivory Effects On Thalassia Testudinum Leaf Growth And Nitrogen Content, J. C. Zieman, R. L. Iverson, John C. Ogden
Integrative Biology Faculty and Staff Publications
The pattern of turtle grazing on Thalassia testudinum in St. Croix seagrass beds begins with the establishment of a grazing plot by initial removal of leaf blades, followed by repeated grazing of several centimeter-long leaf blades within a maintained grazing area. Plants within the grazed area exhibit increased specific growth rate as a consequence of increased light flux to unepiphytized leaf bases. Leaf width is reduced in the grazed area as a consequence of grazing stress. The leaf bases contain a higher proportion of nitrogen and a lower lignin content than the leaf tips, in addition to lacking epiphytes. Our …
Behavior, Habitat Use, Food, And Foraging Efficiency Of Three Species Of Sympatric Merons (Egretta), Donald M. Kent
Behavior, Habitat Use, Food, And Foraging Efficiency Of Three Species Of Sympatric Merons (Egretta), Donald M. Kent
USF Tampa Graduate Theses and Dissertations
The foraging ecology and behavior of Little Bule Herons (Egretta caerulea), Snowy Egrets (E. thula), and Tricolored Herons (E. tricolor) was studied from October 1981 to August 1982 in Old Tampa Bay and Safety Harbor, Hills borough and Pinellas Counties, Florida. Little Blue Herons foraged exclusively by walk-slow and employed head sways or tilted during 75% of the observations. Snowy Egrets used stand, walk-slow, disturb-and-chase, and foot-stirring. Tricolored Herons used stand, walk-slow, disturb-and-chase, ana stand-and-chase. Tricolored Herons using stand-and-chase stood near shore facing open water and when prey was spotted they ran or hopped in the direction of the prey …

he fish community of a large artificial reef made In 1960 of 800 concrete blocks in a seagrass bed on the south coast of St. John, U.S. Virgin Islands, was studied by comparing a series of visual censuses (1975-1979) with each other and with a 1962 total-poison station collection (Randall, 1963). Discounting the presence of some cryptic species in the poison station that would not normally be seen in visual censuses (N = 10), as well as discounting seagrass-bed residents and roaming species only transient on the reef (N = 13), all of the censuses and the poison station (range …

The grazing activities of the tropical echinoid Diadema antillarum Philippi can markedly influence the structure of the shallow-water epibenthic coral reef community. The elimination of an entire Diadema population from a patch reef in St. Croix, U.S. Virgin Islands resulted in a great increase in macro-algal biomass, alterations in species composition, shifts in dominance, an increase in species numbers, and a decrease in equitability. The increase noted in number of species may be indicative of either initial pre-competitive phases of succession or the creation of a new habitat- the micro-canopy. Experiments involving the caging of Diadema have shown that the …
