Identification Of Species Composition In The Hong Kong Shark Fin Trade Using Genetic Techniques And Trader Records, Shelley C. Clarke, Mahmood S. Shivji, Murdoch K. Mcallister Oct 2001

Identification Of Species Composition In The Hong Kong Shark Fin Trade Using Genetic Techniques And Trader Records, Shelley C. Clarke, Mahmood S. Shivji, Murdoch K. Mcallister

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

Trade in shark fins represents one of the most serious threats to shark populations worldwide. Previous studies have indicated that certain types of fins are more valued than others, but due to the largely unregulated and often covert nature of the trade, information on actual species composition has been anecdotal and unverified. In order to examine the potential impacts of the shark fin trade on the abundance of various shark species, a study of the species composition in the world’s largest shark fin trading center, Hong Kong, was initiated. Several approaches for distinguishing the species identity of dried fins were …

Degradation Of Reef Structure, Coral And Fish Communities In The Red Sea By Ship Groundings And Dynamite Fisheries, Bernhard Riegl Sep 2001

Degradation Of Reef Structure, Coral And Fish Communities In The Red Sea By Ship Groundings And Dynamite Fisheries, Bernhard Riegl

Marine & Environmental Sciences Faculty Articles

Reef degradation was investigated on 66 Egyptian Red Sea reefs—60 reefs for dynamite damage (using line transects) and six ship grounding sites (using 1 m sample squares). Ship groundings and dynamite fishing caused similar damage, reduction of the reef to rubble (65% of reefs were dynamited, mostly leeward, 58%). Changes in coral (line transect study) and fish communities (point count study) in impacted sites were documented. On impacted reefs, coral cover decreased, bare substratum and rubble increased, and fish dominance shifted away from Pomacentridae. Oceanographic conditions result in a stable pattern of coral communities (windward Acropora, leeward Porites). …


Site-Dependent Differences In Artificial Reef Function: Implications For Coral Reef Restoration, Robin L. Sherman, David S. Gilliam, Richard E. Spieler Sep 2001

Site-Dependent Differences In Artificial Reef Function: Implications For Coral Reef Restoration, Robin L. Sherman, David S. Gilliam, Richard E. Spieler

Marine & Environmental Sciences Faculty Articles

There is an increasing use of artificial structure in coral reef restoration (for references, see Spieler et al., this volume). Often artificial reef structures are chosen for a restoration project simply because they were used elsewhere. However, it is questionable whether the results obtained at one restoration site can be extrapolated to another. In recent years, several studies have examined the effect of artificial reef site selection on formation of associated fish, algae, and/or invertebrate assemblages (Alevizon et al., 1985; Blinova et al., 1994; Bombace et al., 1994; Caley and St. John, 1996; Chang, 1985; Haughton and Aiken, 1989; Hixon …

Applying Habitat Equivalency Analysis For Coral Reef Damage Assessment And Restoration, J. Walter Milon, Richard E. Dodge (Editor) Sep 2001

Applying Habitat Equivalency Analysis For Coral Reef Damage Assessment And Restoration, J. Walter Milon, Richard E. Dodge (Editor)

Marine & Environmental Sciences Faculty Articles

Quantifying economic damages and restoration measures for injuries to coral reefs has been a difficult task. In the U.S., habitat equivalency analysis (HEA) has emerged as a novel tool that combines biological and economic information to identify replacement habitats of an appropriate scale to substitute for the interim losses resulting from coral reef injuries. This article provides a review of the basic principles underlying HEA and a discussion of important considerations in applying HEA. These considerations include: how to describe coral reef functions and related human uses, recovery rates of coral reef organisms at injured sites with natural and active …


Artificial Substrate And Coral Reef Restoration: What Do We Need To Know To Know What We Need, Richard E. Spieler, David S. Gilliam, Robin L. Sherman Sep 2001

Artificial Substrate And Coral Reef Restoration: What Do We Need To Know To Know What We Need, Richard E. Spieler, David S. Gilliam, Robin L. Sherman

Marine & Environmental Sciences Faculty Articles

To use artificial substrate effectively in coral reef restoration certain basic knowledge is required: (1) what is the artificial substrate expected to accomplish relative to the goals of the restoration effort and (2) what are the expected interactions of the selected substrate’s composition, texture, orientation, and design with the damaged environment and the biota of interest. Whereas the first point is usually clear, at least in general terms, the second is not. In this review, we examine: the functions of artificial substrate in restoration and some of the physical (i.e., composition; surface texture; color and chemistry; and design in terms …


Genetic Evidence For Two Species Of Elephant In Africa, Alfred L. Roca, Nicholas Georgiadis, Jill Pecon-Slattery, Stephen J. O'Brien Aug 2001

Genetic Evidence For Two Species Of Elephant In Africa, Alfred L. Roca, Nicholas Georgiadis, Jill Pecon-Slattery, Stephen J. O'Brien

Biology Faculty Articles

Elephants from the tropical forests of Africa are morphologically distinct from savannah or bush elephants. Dart-biopsy samples from 195 free-ranging African elephants in 21 populations were examined for DNA sequence variation in four nuclear genes (1732 base pairs). Phylogenetic distinctions between African forest elephant and savannah elephant populations corresponded to 58% of the difference in the same genes between elephant genera Loxodonta (African) and Elephas (Asian). Large genetic distance, multiple genetically fixed nucleotide site differences, morphological and habitat distinctions, and extremely limited hybridization of gene flow between forest and savannah elephants support the recognition and conservation management of two African …

The route, which was established based on the subsea survey that was completed in May 2001 by Williamson & Associates, Inc., includes a shore approach from the …


Responses Of Three Coral Communities To The 1997–98 El Niño–Southern Oscillation: Galápagos Islands, Ecuador, Joshua S. Feingold Jul 2001

Responses Of Three Coral Communities To The 1997–98 El Niño–Southern Oscillation: Galápagos Islands, Ecuador, Joshua S. Feingold

Marine & Environmental Sciences Faculty Articles

One deep (13–15 m depth) and two shallow water (1.5 and 7 m) coral communities in the Galápagos Islands, Ecuador were monitored for tissue response (bleaching, paling, morbidity) and secondary responses during and after elevated temperature stress associated with the 1997–98 El Niño–Southern Oscillation (ENSO) event. Between March and May 1998, the fungiid coral Diaseris distorta paled and bleached (up to 88.0% of all individuals bleached) at 13–15 m depth. The small branching colonial coral, Psammocora stellata, paled (79.2% of all colonies) with very little bleaching (11.1%), also at 13–15 m depth. However, by May 1998 colonies of this …

Biology Faculty Articles

Background From studies of genetic polymorphisms and the rate of progression from human immunodeficiency virus type 1 (HIV-1) infection to the acquired immunodeficiency syndrome (AIDS), it appears that the strongest susceptibility is conferred by the major-histocompatibility-complex (MHC) class I type HLA-B*35,Cw*04 allele. However, cytotoxic T-lymphocyte responses have been observed against HIV-1 epitopes presented by HLA-B*3501, the most common HLA-B*35 subtype. We examined subtypes of HLA-B*35 in five cohorts and analyzed the relation of structural differences between HLA-B*35 subtypes to the risk of progression to AIDS. Methods Genotyping of HLA class I loci was performed for 850 patients who seroconverted and …


Trophic Dynamics Of Pinniped Populations In Alaska Using Stable Carbon And Nitrogen Isotope Ratios, Amy Hirons May 2001

Trophic Dynamics Of Pinniped Populations In Alaska Using Stable Carbon And Nitrogen Isotope Ratios, Amy Hirons

Oceanography Faculty Theses and Dissertations

Trophic changes in populations of Stellar sea lions (Eumetorias jubatus), northern fur seals (Callorhinus ursinus) and harbor seals (Phoca vitulina) in the eastern Bering Sea and Gulf of Alaska were studied using stable isotope analysis. Declining populations of all three species of pinnipeds prompted this study to determine if changes in diet, likely resulting from food limitation, contributed to the declines. Stable carbon and nitrogen isotope ratios were analyzed in the vibrissae (whiskers) and body tissues of pinnipeds from 1993-1998 and compared with muscle tissue from prey species during the same time period to determine pinniped trophic dynamics. Vibrissae growth …

Canine And Feline Parvoviruses Can Use Human Or Feline Transferrin Receptors To Bind, Enter, And Infect Cells, John S. L. Parker, William J. Murphy, Dai Wang, Stephen J. O'Brien, Colin R. Parrish Apr 2001

Canine And Feline Parvoviruses Can Use Human Or Feline Transferrin Receptors To Bind, Enter, And Infect Cells, John S. L. Parker, William J. Murphy, Dai Wang, Stephen J. O'Brien, Colin R. Parrish

Biology Faculty Articles

Canine parvovirus (CPV) enters and infects cells by a dynamin-dependent, clathrin-mediated endocytic pathway, and viral capsids colocalize with transferrin in perinuclear vesicles of cells shortly after entry (J. S. L. Parker and C. R. Parrish, J. Virol. 74:1919–1930, 2000). Here we report that CPV and feline panleukopenia virus (FPV), a closely related parvovirus, bind to the human and feline transferrin receptors (TfRs) and use these receptors to enter and infect cells. Capsids did not detectably bind or enter quail QT35 cells or a Chinese hamster ovary (CHO) cell-derived cell line that lacks any TfR (TRVb cells). However, capsids bound and …


An Approach To Parameterization Of The Oceanic Turbulent Boundary Layer In The Western Pacific Warm Pool, Alexander Soloviev, Roger Lukas, Peter Hacker Mar 2001

An Approach To Parameterization Of The Oceanic Turbulent Boundary Layer In The Western Pacific Warm Pool, Alexander Soloviev, Roger Lukas, Peter Hacker

Marine & Environmental Sciences Faculty Articles

Vertical profiles of zonal velocity and the dissipation rate ε of the turbulent kinetic energy obtained during the Tropical Ocean-Global Atmosphere Coupled Ocean-Atmosphere Response Experiment (COARE) are analyzed in the context of planetary boundary layer relationships previously derived from atmospheric measurements. The presence of a barrier layer and the striking effect of increased dimensionless shear and ε at the bottom of the surface mixed layer of the ocean, features often observed in the western Pacific warm pool area, are consistent with the boundary layer laws. The gradient Richardson number Ri is found to be a convenient parameter for scaling the …

Gross Brain Morphology In The Yellow Stingray, Urobatis Jamaicensis, Brian K. Walker, Robin L. Sherman Jan 2001

Gross Brain Morphology In The Yellow Stingray, Urobatis Jamaicensis, Brian K. Walker, Robin L. Sherman

Marine & Environmental Sciences Faculty Articles

The yellow stingray, Urobatis jamaicensis (family Urolophidae), a short-lived, relatively small elasmobranch species (35--40 cm total length), is a common inhabitant of hard bottom and coral reef communities in southeastern Florida and many parts of the Caribbean. A paucity of published studies deal with the yellow stingray, none however on the gross morphology of its nervous system. The gross brain structure of the yellow stingray is compared with previously published studies on other batoid elasmobranchs. The external brain structure of Urobatis jamaicensis was similar to that reported for other Dasyatids, including presence of an asymmetric cerebellum. The bilaterally symmetric brain …

Environmental Analysis Of Cores From The Helike Delta, Gulf Of Corinth, Greece, S. Soter, Patricia Blackwelder, C. Tziavos, D. Katsonopoulou, Terri Hood, Carlos A. Alvarez Zarikian

Marine & Environmental Sciences Faculty Articles

The fan delta southeast of Aigion on the southwest shore of the Gulf of Corinth was the site of ancient Helike, a city destroyed and submerged by an earthquake and seismic sea wave in 373 BC. Bore holes drilled on the Helike Delta yielded numerous ceramic fragments in the upper 12 meters, and a record of changing local environments on the delta during the Holocene period. At about 8 m below present sea level the core profiles show a general upward transition from marine to lacustrine/lagoonalc onditions.T he transition dates from about 8 kyr BP and is probably due to …


Abundance And Distribution Of Commensal Amphipods From Common Marine Sponges Of Southeast Florida, Stacie E. Crowe Jan 2001

Abundance And Distribution Of Commensal Amphipods From Common Marine Sponges Of Southeast Florida, Stacie E. Crowe

HCNSO Student Theses and Dissertations

Marine sponges were examined from shallow waters of southeast Florida and the Florida Keys to determine species composition and distribution of commensal amphipod crustaceans from shallow reef, mangrove, and seagrass habitats. Twenty sponge species were investigated during this study, sixteen of which housed amphipods in the families Colomastigidae and/or Leucothoidae. Six species of commensal amphipods were identified. Leucothoe spinicarpa (Abildgaard) species "complex" was the most dominant amphipod commensal, representing 63% of the total amphipods collected. The L. spinicarpa "complex" contains four local morphotypes, which are diagnosed and briefly described. Common sponge hosts included Callyspongia vaginalis, Mycale sp., and Myriastra kallitetilla.
