Regional Characterisation Of Hard-Bottom Nursery Habitat For Juvenile Caribbean Spiny Lobster (Panulirus Argus) Using Rapid Assessment Techniques, Rodney D. Bertelsen, Mark J. Butler Iv, William F. Herrnkind, John H. Hunt

Biological Sciences Faculty Publications

Shallow, hard-bottom habitat constitutes approximately 30% of the coastal waters of south Florida, United States, yet it is a chronically understudied feature of the marine seascape in this region. In this study, we characterised the general biogeographic and structural features of shallow benthic hard-bottom communities in the Florida Keys, and related those to the abundance of juvenile Caribbean spiny lobster (Panulirus argus), the target of one of Florida's most economically valuable fisheries. We used rapid assessment techniques to survey more than 100 hard-bottom sites in the Florida Keys to estimate the percentage bottom coverage of vegetation (seagrass and …

Endohelminths Of A Snake Mackerel, Gempylus Serpens (Trichiuroidea: Gempylidae), From The Gulf Of Mexico, Charles K. Blend, Norman O. Dronen, James S. Franks, George W. Benz

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Endohelminths are reported from a female snake mackerel, Gempylus serpens (Trichiuroidea: Gempylidae), captured from a depth of 61 m in the Gulf of Mexico 140 km south of the mouth of Mobile Bay, Alabama, in August 1998. A diverse endohelminth parasite fauna was found: 29 plerocercoid type I tetraphyllideans from the lower intestine; 4 didymozoid metacercariae allocated to the collective group Monilicaecum and one didymozoid metacercaria of the collective group Torticaecum from the pyloric cecum; one juvenile Gonocerca phycidis from the stomach; and 5 larvae (L3 stage) comprising 3 species of Anisakis from the pyloric cecum. These nematodes were identified …

Trematoda (Platyhelminthes) Of The Gulf Of Mexico, Robin M. Overstreet, Joshua O. Cook, Richard W. Heard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

First paragraph:

The platyhelminth class Trematoda, consisting of the subclasses Aspidogastrea and Digenea, contains individuals referred to as digeneans, trematodes, or flukes. Aspidogastreans, not digeneans in the strict sense2 number about 80 species in total (Rohde 2005), but adults in the Gulf of Mexico of 4 species have been reported from teleost and chondrichthyan fishes (Hendrix and Overstreet I 977) and one from a turtle (Wharton 1939). Consequently, this chapter deals with trematodes rather than just digeneans, even though all the records but the 5 refer to digeneans. Trematoda is the largest group of platyhelminths, and trematode adults, other than …

Eighteenth Year Of The Gulf Of Maine Environmental Monitoring Program, Lawrence A. Leblanc, Christian Krahforst, Jamie Aube, Shawn Roach, Guy Brun, Gareth Harding, Peter Hennigar, David Page, Stephen H. Jones, Susan Shaw, James Stahlnecker, Jack Schwartz, Darrell Taylor, Bruce Thorpe, Peter Wells

PREP Reports & Publications

This report summarizes the metals and organic contaminant data associated with the collection and analyses of blue mussel (Mytilus edulis) tissue from selected sites along the Gulf of Maine coast during the 2008 sampling season. Contaminant monitoring is conducted by the Gulfwatch Program for the Gulf of Maine Council on the Marine Environment (GOMC). A subset of these data is compared with analytical results from earlier Gulfwatch monitoring (2001-2007). Statistical analyses are limited to descriptive measures of replicates from selected sampling sites and include: arithmetic means, and appropriate measures of variance. The primary purpose of this report is to present …

Dynamically Constrained Ensemble Perturbations: Application To Tides On The West Florida Shelf, Alexander Barth, Aida Alvera-Azcarate, J. M. Beckers, Robert H. Weisberg, L. Vandenbulcke, F. Lenartz, M. Rixen

Marine Science Faculty Publications

A method is presented to create an ensemble of perturbations that satisfies linear dynamical constraints. A cost function is formulated defining the probability of each perturbation. It is shown that the perturbations created with this approach take the land-sea mask into account in a similar way as variational analysis techniques. The impact of the land-sea mask is illustrated with an idealized configuration of a barrier island. Perturbations with a spatially variable correlation length can be also created by this approach. The method is applied to a realistic configuration of the West Florida Shelf to create perturbations of the M2 tidal …

Patterns Of Spiny Lobster (Panulirus Argus) Postlarval Recruitment In The Carribbean: A Crtr Project, Mark J. Butler Iv, Angela M.

As part of the Coral Reef Targeted Research (CRTR) Program, a partnership between the Global Environment Facility and the World Bank, our research team examined the recruitment patterns of Caribbean spiny lobster (Panulirus argus) postlarvae among regions in the Caribbean, with a particular focus on Mesoamerica. Our goal was to collect comparable information on postlarval supply among regions and to provide data to test predictions of connectivity generated from a coupled biophysical oceanographic model of lobster larval dispersal. Here we present the results of the postlarval recruitment monitoring program. We monitored the catch of postlarvae on Witham-style collectors …

Phytoplankton Blooms: Their Occurence And Composition Within Virginia's Tidal Tributaries, Harold G. Marshall, Todd A. Egerton

Biological Sciences Faculty Publications

Sporadic algal bloom development within a 10 year monitoring program in Virginia tidal tributaries of Chesapeake Bay is reviewed. These blooms were common events, characteristically producing a color signature to the surface water, typically short lived, occurring mainly from spring into autumn throughout different salinity regions of these rivers, and were produced primarily by dinoflagellates. The abundance threshold levels that would identify bloom status from a non-bloom presence were species specific, varied with the taxon's cell size, and ranged from ca. 10 to 10(4) cells mL(-1). Among the most consistent sporadic bloom producers were the dinoflagellates Akashiwo sanguinea, Cochlodinium …

Satellite-Detected Fluorescence Reveals Global Physiology Of Ocean Phytoplankton, Michael J. Behrenfeld, T.K. Westberry, Emmanuel Boss, R.T. O'Malley, D.A. Siegel, Jerry D. Wiggert, B.A. Franz, G.C. Feldman, S.C. Doney, J.K. Moore, G. Dall'olmo, A.J. Milligan, I. Lima, N. Mahowald

Phytoplankton photosynthesis links global ocean biology and climate-driven fluctuations in the physical environment. These interactions are largely expressed through changes in phytoplankton physiology, but physiological status has proven extremely challenging to characterize globally. Phytoplankton fluorescence does provide a rich source of physiological information long exploited in laboratory and field studies, and is now observed from space. Here we evaluate the physiological underpinnings of global variations in satellite-based phytoplankton chlorophyll fluorescence. The three dominant factors influencing fluorescence distributions are chlorophyll concentration, pigment packaging effects on light absorption, and light-dependent energy-quenching processes. After accounting for these three factors, resultant global distributions of …

Genetic Variation For Carcass Quality Traits In Cultured Sea Bass (Dicentrarchus Labrax), Eric A. Saillant, Mathilde Dupont-Nivet, Marie Sabourault, Pierrick Haffray, Stanislas Laureau, Marie-Odile Vidal, Béatrice Chatain

Faculty Publications

Genetic parameters for carcass quality traits were estimated in 27 families of sea bass (3 dams x 9 sires factorial mating design), raised mixed in the same tanks starting before hatching. O. spring parentage was determined a posteriori using 6 microsatellite loci. Carcass quality traits were recorded at 818 days post fertilization (mean standard length: 32.6 +/- 3.1 cm). Genetic parameters were estimated from the sire half sib variance and covariance components. Heritability of body weight (BW) and carcass processing traits (standardized to body weight) percent head weight (Head%), percent viscera weight (Viscera%) and percent visceral fat weight (VisceFat%) were …
