Faculty Publications

The type material of Polylekithum ictaluri, P. halli, and Maculifer chandleri was examined from the United States National Parasite Museum, and we determined that the material was conspecific, making P. halli and M. chandleri junior subjective synonyms of P. ictaluri. Polylekithum catahoulensis sp. nov. was described from material collected from catfishes at the Catahoula Wildlife Refuge, LaSalle Parish, Louisiana, USA, and compared with P. ictaluri collected from catfishes in Reelfoot Lake, Obion County, Tennessee, USA, and the Pearl River, Hancock County, Mississippi, USA. Polylekithum catahoulensis had smaller eggs (77–88 μm long by 51–63 μm wide vs. 94–108 μm by …

Responses To Salinity Of Color Polymorphs In Two Populations Of The Sea Star, Pisaster Achraceus, Viren Johann Perumal

Loma Linda University Electronic Theses, Dissertations & Projects

Pisaster ochraceus was analyzed to determine if varying salinities, animal color, or location affect the physiology of these sea stars. The three responses analyzed were aerobic respiration, ammonia excretion, and self-righting. The tested variables included two different color morphs (orange and purple) of P. ochraceus, two different locations (open coast and inland straits) in Washington State, and three salinities (22, 30, and 40 psu).

Wet mass-specific oxygen consumption rates were not significantly affected by color, location, or salinity, and Dry mass-specific oxygen consumption rates showed no significant differences for main effects, but a three-way interaction was identified. Similarly, ammonia …

[1] Carbon flux models based on light use efficiency (LUE), such as the MOD17 algorithm, have proved difficult to parameterize because of uncertainties in the LUE term, which is usually estimated from meteorological variables available only at large spatial scales. In search of simpler models based entirely on remote‐sensing data, we examined direct relationships between the enhanced vegetation index (EVI) and gross primary productivity (GPP) measured at nine eddy covariance flux tower sites across North America. When data from the winter period of inactive photosynthesis were excluded, the overall relationship between EVI and tower GPP was better than that between …

Coral-Based Climate Variability In The Western Pacific Warm Pool Since 1867, Terrence M. Quinn, Frederick W. Taylor, Thomas J. Crowley

Marine Science Faculty Publications

We have generated monthly resolved, stable isotope (δ¹⁸O and δ¹³C) and Sr/Ca time series from a massive Porites coral from Rabaul (4°S, 152°E): a site located in the warmest sector of the Western Pacific Warm Pool (WPWP). The coral δ¹⁸O and Sr/Ca time series are well correlated to each other and positive excursions in both records coincide with times of ENSO warm phase events. These time series contain abundant interannual variability that exhibits the well‐recognized pattern of low amplitude ENSO variation between ∼1920–1960 and high amplitude ENSO variation between 1880–1920 and 1960–1997. The …

Independent data from the Gulf of Mexico are used to develop and test the hypothesis that the same sequence of physical and ecological events each year allows the toxic dinoflagellate Karenia brevis to become dominant. A phosphorus-rich nutrient supply initiates phytoplankton succession, once deposition events of Saharan iron-rich dust allow Trichodesmium blooms to utilize ubiquitous dissolved nitrogen gas within otherwise nitrogen-poor sea water. They and the co-occurring K. brevis are positioned within the bottom Ekman layers, as a consequence of their similar diel vertical migration patterns on the middle shelf.

Validity, Identification, And Distribution Of The Roundscale Spearfish, Tetrapturus Georgii (Teleostei: Istiophoridae): Morphological And Molecular Evidence, Mahmood S. Shivji, Jennifer E. Magnussen, Lawrence R. Beerkircher, George Hinteregger, Dennis W. Lee, Joseph E. Serafy, Eric D. Prince

Marine & Environmental Sciences Faculty Articles

The roundscale spearfish, Tetrapturus georgii Lowe, 1840, is known only from four specimens from the Mediterranean and eastern North Atlantic. Additional specimens have not been identified since 1961, making the validity and distribution of this species unclear. Analysis of 16 billfish specimens from the western North Atlantic on the basis of scale morphology, anus position, and mitochondrial DNA confirms the validity of this species and extends its distribution. Mid-lateral scales are soft, notably rounded anteriorly, and bear 2–3 points distinct from those of the sympatric longbill spearfish (Tetrapturus pfluegeri Robins and de Sylva, 1963) and white marlin (Tetrapturus …

Biological Sciences Faculty Publications

Panulirus argus Virus 1 (PaV1) is the first virus known to be pathogenic to a wild lobster. It infects the Caribbean spiny lobster P. argus from the Florida Keys, and has a predilection for juveniles. The monitoring of the virus in wild populations and study of its behavior in the laboratory require the development of reliable diagnostic tools. A sensitive and specific fluorescence in situ hybridization (FISH) assay was developed for detection of PaV1. The lower detection limit using a 110 bp DNA probe in a dot-blot hybridization for PaV1 DNA was 10 pg of cloned template PaV1 DNA and …

A Decade Of Changes For Virginia Freshwater Aquaculture (1993-2003), Scott H. Newton

Virginia Journal of Science

Aquaculture surveys were designed and initiated along with the writing of the State Aquaculture Plan during 1993 to 1995. The first Virginia Aquaculture Survey, conducted for the production year 1993, established the status of both freshwater and marine commercial industries. Subsequent surveys were conducted to trace industry developments relevant to production aspects and economic impacts. Survey data from Virginia Agricultural Statistics Service Reports for 1993, 1995, 1997, and 2003 summarize a decade of Virginia freshwater aquaculture information. Significant changes in sales among the principal aquaculture species occurred over the 10-year period. The 1993 freshwater aquaculture value of $2.8 million increased …

Characterization Of Β-Lactam Resistant Pandemic Serotypes Of Vibrio Cholerae Isolated From Ships' Ballast Tanks And Coastal Waters, Amanda Lynn Goodrich

OES Theses and Dissertations

Vibrio cholerae serotypes 01 and 0139 are responsible for world-wide epidemics of cholera. These pandemic causing strains must possess genes that encode for the cholera toxin (CTX) and toxin co-regulated pili (TCP) in order to infect their hosts. In this study, 284 isolates of Vibrio cholerae from ballast and coastal waters were serotyped, with 11 % testing positive for serotype 01 and 21 % testing positive for serotype 0139. PCR assays were used to detect the presence of ctxA and tcpA genes in all positive isolates, none of which contained ctxA while 2% of the isolates contained tcpA. The 01 …

Fisheries Research Contract Report No. 15 - Aquatic Animal Health Subprogram: Pilchard Herpesvirus Infection In Wild Pilchards (Frdc Project No. 2002/044) Final Report, Brian Jones, Melanie Crockford, Richard Whittington, Mark Crane, Graham Wilcox

Fisheries Research Contract Reports

In 1995 and again in 1998/9, millions of pilchards (Sardinops sagax neopilchardus) were found dead or dying off the coast of Australia. Some pilchards in New Zealand were also affected during the 1995 epizootic. The epizootics moved progressively in a "bushfire-like" manner against the prevailing currents at a rapid speed. An uncharacterised herpesvirus, pilchard herpesvirus (PHV), was associated with both mortality events and, based on its occurrence in affected fish and the disease pathogenesis, generally accepted as the causative agent, although experimental evidence of its role was not established. Until recently, rapid and sensitive methods to detect PHV were not …

The intention of this report was to provide a summary of information on crab stocks in the region, not to alter the current management arrangements. This report describes experimental sampling, commercial catch statistics, commercial catch monitoring and surveys of recreational fishers to …

Morphological And Phylogenetic Description Of An Unusual Amphidinium (Dinophyceae) Species, Tyler Cyronak, Isaac R. Santos

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

Amphidinium carterae, an important harmful algal species that produces powerful antifungal and hemolytic compounds (amphidinols) and cytotoxic macrolides (amphidinolides) is ubiquitous in coastal waters. Samples from coral rubble contained an unusual and previously unreported Amphidinium (D2) with a circular outline. Genetic analysis of clone D2 of this species, involving the sequencing of large subunit (LSU) rDNA, revealed a relationship between Amphidinium sp. D2 and both A. carterae and A. massartii. However, morphological and genetic differences suggest that Amphidinium sp. D2 is not conspecific with A. carterae or A. massartii. Further studies to describe this species are presently …

Great Bay Estuary Restoration Compendium, Jay Odell, Alyson L. Eberhardt, David M. Burdick, Pete Ingraham

PREP Reports & Publications

Single species approaches to natural resource conservation and management are now viewed as antiquated and oversimplified for dealing with complex systems. Scientists and managers who work in estuaries and other marine systems have urged adoption of ecosystem based approaches to management for nearly a decade, yet practitioners are still struggling to translate the ideas into practice. Similarly, ecological restoration projects in coastal systems have typically addressed one species or habitat. In recent years, efforts to focus on multiple species and habitats have increased. Our project developed an integrated ecosystem approach to identify multi-habitat restoration opportunities in the Great Bay estuary, …

Documenting Decadal Spatial Changes In Seagrass And Acropora Palmata Cover By Aerial Photography Analysis In Vieques, Puerto Rico: 1937-2000, Luz Raquel Hernandez-Cruz, Samuel J. Purkis, Bernhard Riegl

Marine & Environmental Sciences Faculty Articles

Aerial photographs from 1937–2000 of Bahía Salina del Sur on vieques, Puerto Rico were analyzed to detect and describe spatial changes in the areal cover of sea-grass beds in Bahía Salina del Sur. The images were pre-processed to minimize noise and unsupervised classification was used to detect areas colonized by seagrass. The number of individual seagrass patches, direction, and characteristic of growth were quantified and described. Seagrass coverage increased by 85.8% over the 64-yr period and this increase was best described by a 2nd order polynomial function (r² = 0.91). Between 1937 and 2000, the spatial expression of the …

Evaluation Of New Grace Time-Variable Gravity Data Over The Ocean, Don P. Chambers

Marine Science Faculty Publications

Monthly GRACE gravity field models from the three science processing centers (CSR, GFZ, and JPL) are analyzed for the period from February 2003 to April 2005 over the ocean. The data are used to estimate maps of the mass component of sea level at smoothing radii of 500 km and 750 km. In addition to using new gravity field models, a filter has been applied to estimate and remove systematic errors in the coefficients that cause erroneous patterns in the maps of equivalent water level. The filter is described and its effects are discussed. The GRACE maps have been evaluated …

Distribution, Morphology, And Genetic Affinities Of Dwarf Embedded Fucus Populations From The Northwest Atlantic Ocean, Arthur C. Mathieson, Clinton J. Dawes, Aaron L. Wallace, Anita S. Klein

New Hampshire Agricultural Experiment Station Publications

Dwarf embedded Fucus populations in the Northwest Atlantic Ocean are restricted to the upper intertidal zone in sandy salt marsh environments; they lack holdfasts and are from attached parental populations of F. spiralis or F. spiralis x F. vesiculosus hybrids after breakage and entanglement with halophytic marsh grasses. Dwarf forms are dichotomously branched, flat, and have a mean overall length and width of 20.3 and 1.3 mm, respectively. Thus, they are longer than Irish (mean 9.3 mm) and Alaskan (mean 15.0 mm) populations identified as F cottonii. Reciprocal transplants of different Fucus taxa in a Maine salt marsh confirm that …
