Isolation Of A Cdna Clone For The Human Laminin-B1 Chain And Its Gene Localization, Michael Jaye, William Modi, George A. Ricca, Robert Mudd, Inc-Ming Chiu, Stephen J. O'Brien, William N. Drohan

Biology Faculty Articles

A cDNA clone encoding the B1 chain of human laminin has been isolated from a human endothelial cell cDNA library. With use of this probe and a panel of rodent/human somatic-cell hybrids and in situ hybridization, the gene for the human laminin-B1 chain has been localized to chromosome 7, band q31.

Effects Of A Dispersed And Undispersed Crude Oil On Mangroves, Seagrasses And Corals, T. G. Ballou, Richard E. Dodge, S. C. Hess, A. H. Knap, Thomas D. Sleeter

Marine & Environmental Sciences Faculty Reports

The primary objective of this study was to evaluate the application of dispersant to spilled oil as a means of reducing adverse environmental effects of oil spills in nearshore, tropical waters. The results of numerous laboratory and field studies have suggested that dispersants may play a useful role in reducing adverse impacts on sensitive and valued environments such as mangroves, seagrasses, and corals. However, the use of dispersants has not been allowed thus far in most situations because of a lack of direct experimental data on the various effects of dispersants and the environmental trade-offs presumed to occur as a …

Growth Rate Of Stony Corals Of Broward County, Florida: Effects From Past Beach Renourishment Projects, Richard E. Dodge, Broward County Erosion Prevention District Environmental Quality Control Board

Marine & Environmental Sciences Faculty Reports

The skeletal growth of hermatypic (reef-building) corals is a sensitive indicator of environmental conditions and perturbations. In particular, excessive sedimentation and turbidity act to depress coral growth because energy expenditure is required to remove sediment and because turbidity reduces light energy necessary for coral health and nutrition.

Normalized annual growth (linear skeletal extension) rates of Broward County, Florida reef-building corals were over 16 years (1985-1970). Star corals (Montastrea annularis) and brain corals (Diploria labyrinthiformis) were collected from each of four reef sites at two depths (9m and 18m). Collection areas were located in the vicinity of …

A New Moderately Repetitive Dna Sequence Family Of Novel Organization, Neal D. Epstein, S. Karlsson, Stephen J. O'Brien, William S. Modi, A. Moulton, Arthur W. Nienhuis

Biology Faculty Articles

In cloning adenovirus homologous sequences, from a human cosmid library, we identified a moderately repetitive DNA sequence family consisting of tandem arrays of 2.5 kb members. A member was sequenced and several non-adjacent, 15–20 bp G-C rich segments with homology to the left side of adenovirus were discovered. The copy number of 400 members is highly conserved among humans. Southern blots of partial digests of human DNA have verified the tandem array of the sequence family. The chromosomal location was defined by somatic cell genetics and in situ hybridization. Tandem arrays are found only on chromosomes 4 (4q31) and 19 …

A New Species Of Chevalia From The Caribbean Sea (Crustacea: Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new Caribbean species, Chevalia carpenteri is described; heretofore only one species of the genus was known, but we have examined material that suggests morphs may represent distinct species or subspecies. We report C. mexicana and extend its range from the northern Gulf of Mexico to Belize. Our new species differs from the world complex of C. aviculae morphs in the ovate article 2 of pereopods 5-7 and the posteriorly flat epimera with large notches.

The Indo-Pacific Audulla Chelifera Reported From The Caribbean Sea (Crustacea: Amphipoda), James Darwin Thomas, J. L. Barnard

Marine & Environmental Sciences Faculty Articles

Audulla chelifera Chevreux is reported for the first time outside of the Indian Ocean and Red Sea. It has now been found in the western Caribbean inhabiting the alga Turbinaria turbinata (Linneaus) Kuntze in backreef regions of the Belize barrier reef.

New Species Of Neomegamphopus From Tropical America (Crustacea: Marine Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Neomegamphopus hiatus is described from Venezuela and the Florida Keys, N. pachiatus and N. heardi from Pacific Panama, and N. kalanii from eastern Florida. Neomegamphopus hiatus and N. pachiatus differ from a close congener, N. roosevelti (tropical eastern Pacific), in the much larger coxa 1 of mature males, the less setose gnathopods, and the broader carpus of the first gnathopod bearing a much deeper incision defining the posterior tooth; the carpus is much shorter and stouter in N. hiatus and N. pachiatus than in N. roosevelti. Neomegamphopus heardi differs from the other species in the bifid tooth on the …

A Comparison Of The Relative Sediment Transport Of Quartz And Aragonite Sand For Use As Beach Renourishment Materials In South Florida, Brian Lewis Lipsitz

HCNSO Student Theses and Dissertations

An evaluation of the relative rates of sediment transport of an oolitic aragonite sand and a quartz quarry sand as possible beach renourishment materials has been conducted. When comparing equal volumes, the aragonite experienced less transport than the quartz in both the longshore and in the onshore-offshore directions. When comparing equal size fractions, in sizes 0.35mm and smaller, aragonite was less transportable. The quartz was less transportable in the sizes greater than 0.35mm. This trend was observed in two separate experiments and is attributed to the effective density ratio of aragonite to quartz, dissimilarities in roundness and sphericity, and to …

Coliphage As An Indicator Of Fecal Pollution In Marine Waters: Assay, Validation, And Application, Donald S. Mccorquodale Jr.

HCNSO Student Theses and Dissertations

Escherichia coli, the preferred bacterial indicator for fecal pollution in fresh waters, does not conform to the concept of an indicator microorganism because it is rapidly killed or inactivated by seawater. This series of papers investigated the value of coliphage, a virus which infects E. coli, as an indicator of pollution in saline waters. In order to be an accurate indicator an organism must (1) be ubiquitous in wastewater, (2) survive and be detectable at least as long as the harmful organisms, and (3) be easy to isolate and identify.

A review of the literature determined that coliphage …
