Four Species Of Synopiidae From The Caribbean Region (Crustacea: Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Synopia ultramarina is redescribed from the Gulf Stream and the Florida Keys and comments are made on the tangled taxonomy in Synopia. Tiron bellairsi, originally described from Barbados, is reported from Belize, at the opposite side of the Caribbean Basin. Garosyrrhoe bigarra, a Pacific species, is also reported from Belize, but no clear subspecific differences are detected as yet between Pacific and Atlantic populations.

A New Species, Ampelisca Burkei, (Crustacea, Amphipoda) From Florida, J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new species Ampelisca burkei, from Florida, is described. This species appears to be very close to A. lobata Holmes, from the eastern Pacific Ocean, but differs in the shape and setation of article 4 on pereopod 7, and the presence of an anteroventral spine-seta on article 5 of pereopod 7.

The Physiological Implications Of Bleaching Of Corals Off Southeast Florida, C. J. Reese, G. S. Kleppel, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

As part of an ongoing study of coral bleaching, observations were made of corals on reefs (ca. 8m) off John U. Lloyd Beach, Dania, FL, in December, 1987. Bleaching was evident in approximately 50% of Montastrea annularis, the dominant scleractinian coral species. Quantitative pigment measurements by HPLC show that bleached corals contained

Decline Of Coral Growth Rates At Negril, Jamaica, T. J. Goreau, Richard E. Dodge, P. D. Goreau

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Montastrea annularis heads were collected near Negril, Jamaica, along transects from open, normal reef conditions into the mouths of rivers draining the Negril Morass. Corals subject to turbidity (particulate peat and dissolved humic compouonds near rivers, re-suspended reef sediments away from them) were growing more slowly than those in normal circumstances. Surprisingly, corals growing fastest were slowing the most, and the slowest growers increasing growth rate. Linear regression analysis of growth trends over the past two decades revealed stable limit-cycle behavior: change of growth was inversely proportional to growth rate, with a very significant correlation coefficient of -0.92. We suggest …

Vadosiapus Copacabanus, A New Genus And Species Of Exoedicerotidae From Brazil (Crustacea, Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Vadosiapus copacabanus, n. gen. is described from the surf zone on the beach at Copacabana, Rio de Janeiro, Brazil. The genus and unique species is related to the three known species of Bathyporeiapus, which range southward from Brazil through the Magellan region of South America. Vadosiapus is distinguished from Bathyporeiapus in the odd phoxocephalid-like article 3 of the mandibular palp, the nonsinuate epimeron 2, the broadened tel son bearing only midsagittal armaments and the enlarged dactyl of gnathopod 2.

Elasmopus Balkomanus, A New Species From The Florida Keys (Crustacea, Amphipoda), James Darwin Thomas, J. L. Barnard

Marine & Environmental Sciences Faculty Articles

Elasmopus balkomanus is described from Looe Key Reef in the Florida Keys. The species is very close to the eastern Pacific E. antennatus but in the male has equally extending rami on uropod 3, only 2 (versus 4-6) spines on each lobe of the tel son in adults, a lateral ridge on the propodus of male gnathopod 2 and very heavily armed flagella of antenna 2 in the male.

This species lives in a short-tufted algal turf community on coral rubble but apparently is rare because it has only been collected once in 10 years of sampling in the Florida …

Ipanemidae, New Family, Ipanema Talpa, New Genus And Species, From The Surf Zone Of Brazil (Crustacea: Amphipoda: Haustorioidea), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new family of haustorioid Amphipoda resembling the Phoxocephalopsidae and Urothoidae has been discovered in sands of the surf zone off Rio de Janeiro, Brazil. Like the recently described Cheidae, the new speciesgenus- family combines various characters of haustorioids in a unique manner and bears one unprecedented apomorphic character: an alate, uncleft telson.

The new taxon has the following characters of Urothoidae: antenna 2, head, and distal parts of pereopods but has a distinctive antenna I, coxae 1-2, mandibular palp, telson and epimera 1-2. Ipanema has the following characters of Phoxocephalopsidae: coxae, mandibles, and uropod I but has distinctive antennae …

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 …

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.

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.

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 …

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 …

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 …
