Biozonation Of Deep-Water Lithoherms And Associated Hardgrounds In The Northeastern Straits Of Florida, Charles G. Messing, A. Conrad Neumann, Judith C. Lang

Marine & Environmental Sciences Faculty Articles

Elongated carbonate mounds ("lithoherms") oriented parallel to prevailing northerly bottom currents at moderate depths (500-700 m) along the western margin of the Little Bahama Bank exhibit a consistent faunal zonation characterized by attached, suspension-feeding invertebrates. The four most abundant macroepibenthic groups (alcyonarians, crinoids, sponges and stylasterid hydrocorals) dominate all hard substrates examined except upcurrent ends and crests of lithoherms. We recognize three faunal zones on these mounds: a Coral Zone (Lophelia prolifera) restricted to the upcurrent end; a Zoanthid Zone (?Gerardia sp.) along upcurrent crests, and a Crinoid/Alcyonarian Zone along lithoherm flanks and downstream crests. Taxa characteristic of the latter …

Ensayara Jumane, A New Species From Belize, Caribbean Sea (Amphipoda, Lysianassidae), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Ensayara jumane is described from Belize. It differs from the west Mexican Ensayara ramonella J. L. Barnard (1964) in the excavate posteroventral margins of article 2 on pereopods 5-7, and the sparse (9 versus 25) setae on articles 5-6 of gnathopod I. A new diagnosis for Ensayara, a key to species, list of species, references to original descriptions and geographic codes for each species are provided. This is the first record of the genus from the Caribbean Sea.

Gitana Dominica, A New Species From The Caribbean Sea (Amphipoda: Amphilochidae), James Darwin Thomas, J. L. Barnard

Marine & Environmental Sciences Faculty Articles

The new species Gitana dominica is described from Dominica in the Lesser Antilles; it is the first record of the genus from the western Atlantic Ocean. The new species differs from its closest relative, Gitana calitemplado, from California, in the shorter and posteroventrally excavate coxa 1. Gitana is reviewed.

Analysis Of Benthic Macroinvertebrate Assemblages Birch Landings, Fort Lauderdale, Fl, Charles G. Messing

Marine & Environmental Sciences Faculty Reports

Quantitative analysis of benthic macroinvertebrate assemblages in the Intracoastal Waterway in an area of proposed dredge and fill adjacent to existing sea wall at Birch Landings, Fort Lauderdale, FL (Broward County) reveals a community dominated by a small number of annelid worm species typical of stressed, high organic content, moderately reduced salinity, estuarine and canal habitats found along much of coastal south Florida. It is concluded that the proposed construction will impact no unique assemblage of organisms nor affect significantly the population resources of any macroinvertebrate species.

Sea Turtle Conservation Program, Broward County, Fl 1990 Report, Curtis M. Burney, Catherine A. Mattison

Marine & Environmental Sciences Faculty Reports

Since 1978, the Broward County Environmental Protection Department (BCEPD) has provided for the conservation of endangered and threatened sea turtle species within its area of responsibility. Broward County is within the normal nesting areas of three species of sea turtles: the loggerhead sea turtle (Caretta caretta), the green sea turtle (Chelonia mydas) and the leatherback sea turtle (Dermochelys coriacea). The loggerhead is listed as a threatened species, while the green and leatherback are listed as endangered under the U.S. Endangered Species Act, 1973, and Chapter 370, F.S.

Since these statutes strictly forbid any disturbance …

Chromosomal Localization Of Nucleic Acid-Binding Proteins By Affinity Mapping: Assignment Of The Ire-Binding Protein Gene To Human Chromosome 9, Matthias W. Hentze, Hector Seuanez, Stephen J. O'Brien, Joe B. Harford, Richard D. Klausner

Biology Faculty Articles

Three human mRNAs are regulated post-transcriptionally by iron via iron-responsive elements (IREs) contained in each mRNA. A cytoplasmic protein (IRE-BP) binds to these cis-acting elements and mediates the translational regulation of ferritin H- and L-chain mRNA and the iron-dependent stability of transferrin receptor (TfR) mRNA. We have taken advantage of the different mobilities of the human and rodent IRE/IRE-BP complexes on non-denaturing polyacrylamide gels to determine the chromosomal localization of the gene encoding the IRE-BP. Utilizing a panel of 34 different human/rodent hybrid cell lines we have assigned the IRE-BP gene to human chromosome 9. This new technique based on …

The T(11;14)(P15;Q11) In A T-Cell Acute Lymphoblastic Leukemia Cell Line Activates Multiple Transcripts, Including Ttg-1, A Gene Encoding A Potential Zinc Finger Protein, Elizabeth A. Mcguire, Richard D. Hockett, Karen M. Pollock, Marty F. Bartholdi, Stephen J. O'Brien, Stanley J. Korsmeyer

Biology Faculty Articles

Interchromosomal translocations within lymphoid neoplasms frequently involve the antigen receptor genes. We cloned the breakpoints of the t(11;14)(p15;q11) in a CD3-negative T-cell acute lymphoblastic leukemia cell line (RPMI 8402) in order to identify new genes potentially involved in T-cell neoplasia. An extensive comparison of both breakpoints and their germ line counterparts indicated that an inadvertant recombinase-mediated break at chromosome segment 11p15 recombined with the delta T-cell receptor at 14q11. The derivative 11 breakpoint resembles a coding joint in which 11p15 rather than a variable region was introduced 5' to a D_δ1D_δ2J_δ1 intermediate rearrangement. Conversely, the …

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 Gli-Kruppel Family Of Human Genes, John M. Ruppert, Kenneth W. Kinzler, Albert J. Wong, Sandra H. Bigner, Fa-Ten Kao, Martha L. Law, Hector Seuanez, Stephen J. O'Brien, Bert Vogelstein

Biology Faculty Articles

Previous characterization of GLI, a gene found to be amplified and expressed in a subset of human brain tumors, revealed the presence of five tandem zinc fingers related to those of Krüppel (Kr), a Drosophila segmentation gene of the gap class. We have used the GLI cDNA as a molecular probe to isolate related sequences from the human genome. Partial characterization of six related loci, including sequence determination, expression studies, and chromosome localization, revealed that each locus could encode a separate finger protein. The predicted proteins all had similar H-C links, i.e., a conserved stretch of 9 …

The Κ-Deleting Element: Germline And Rearranged, Duplicated And Dispersed Forms, Winfried B. Graninger, Paula L. Goldman, Cynthia C. Morton, Stephen J. O'Brien, Stanley J. Korsmeyer

Biology Faculty Articles

Human light chain genes are used in a κ before λ order. Accompanying this hierarchy is the rearrangement of a κ-deleting element (Kde) which eliminates the kappa locus before λ gene rearrangement. In approximately 60% of rearrangements the Kde recombines at a conserved heptamer within the J_κ-C_κ intron. We demonstrated that aberrant V/J rearrangements possessing apparent "N" nucleotides existed 5' to the J_κ-Kde rearrangements. This suggests that the Kde may selectively eliminate nonfunctional V/J alleles. A κ-producing cell that displayed the unusual finding of λ gene rearrangement demonstrated a rearranged Kde. This rearrangement was a …

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 …
