Multiple Spatial Scale Assessment Of Coral Reef And Hard-Bottom Community Structure In The Florida Keys National Marine Sanctuary, Steven Miller, Dione W. Swanson, Mark Chiappone

The zoning plan for the Florida Keys National Marine Sanctuary (FKNMS) established 23 relatively small no-fishing zones distributed mostly along the offshore reef tract in 1997. In 1999, a two-stage, stratified random sampling design based on the proportion of coral reef and hard-bottom types within the FKNMS was conducted. Our study focused on differences in coverage, density, and condition of benthic organisms with respect to habitat type, regional variations, and differences between no-fishing zones and reference sites at 80 locations spanning 200 km. Most variables exhibited significant spatial differences by habitat type or between individual no-fishing zones and reference sites …
A Taxonomic Evaluation Of The Comatulid Genus Stephanometra (Echinodermata:Crinoidea), Dana Lin Rankin
A Taxonomic Evaluation Of The Comatulid Genus Stephanometra (Echinodermata:Crinoidea), Dana Lin Rankin
HCNSO Student Theses and Dissertations
Several genera in the comatulid family Mariametridae are currently ambiguously distinguished on the basis of variations in length and robustness of oral pinnules. Previous descriptions have suggested that at least the genera Stephanometra and Lamprometra are imperfectly distinguishable. A detailed re-examination of morphology coupled with principal component analyses of morphometric data and cladistic analyses provide support for a monophyletic Stephanometra distinct from Lamprometra. A preliminary morphological analysis suggests that Dichrometra and Liparometra should be synonymized with Lamprometra. The six currently recognized species of Stephanometra uniquely share at least one pair of oral pinnules characterized by enlarged size, reduced ambulacral groove …

Horizontal Structure Of The Upper Ocean Velocity And Density Fields In The Western Equatorial Pacific Warm Pool: Depth Range From 20 To 250 M, Alexander Soloviev, Roger Lukas, Peter Hacker
Horizontal Structure Of The Upper Ocean Velocity And Density Fields In The Western Equatorial Pacific Warm Pool: Depth Range From 20 To 250 M, Alexander Soloviev, Roger Lukas, Peter Hacker
Marine & Environmental Sciences Faculty Articles
Wavenumber spectra of velocity and density fields in the western equatorial Pacific warm pool on scales 6–120 km are estimated using the shipboard survey data collected during the TOGA Coupled Ocean–Atmosphere Response Experiment (COARE). The spectra are averaged over three depth intervals: 20–60, 60–110, and 110–250 m (corresponding to the Yoshida jet, the South Equatorial Current, and the southern edge of Equatorial Undercurrent). The velocity spectra are corrected for the mean flow shear advection, which is important under conditions of low gradient Richardson number (Ri). After that, both velocity and density spectra are consistent with an internal wave spectral model …

Acth4 -10, Substance P, And Dizolcipine (Mk-801) Accelerate Functional Recovery After Hemilabyrinthectomy In Goldfish, Rosana Mattioli, Joseph P. Huston, Richard E. Spieler
Acth4 -10, Substance P, And Dizolcipine (Mk-801) Accelerate Functional Recovery After Hemilabyrinthectomy In Goldfish, Rosana Mattioli, Joseph P. Huston, Richard E. Spieler

In this study, we evaluated the goldfish model of hemilabyrinthectomy for investigating potential recovery-promoting drugs. In this lesion model, the unilateral removal of the labyrinth induces a postural imbalance in response to light (Dorsal Light Reflex), from which the animals can recover over time. The behavioral effects of two neuropeptides were tested–namely, of substance P and ACTH4-10, both of which are known to promote functional recovery in several other lesion models. Furthermore, the effect of MK- 801, an antagonist of the glutamatergic NMDAreceptor subtype, was tested because this substance has also been shown to exert a neuroprotective effect. After lesion …

In 1997, 271 scleractinian corals growing on a sewer outfall pipe were used in a transplantation study offshore from North Dade County, Florida, USA. Corals were removed from the outfall pipe and transplanted onto concrete armor mat tiles used to cover the pipe. Success (number of corals still attached and alive), mortality (number of dead corals), and growth rates of the transplants were assessed between December 1997 and December 1999. Colony surface area and radius length were measured on scanned photographs to estimate horizontal growth rate. After two years post-transplantation, success rate and overall mortality were 87% and 7.8% respectively. …
Skeletal Architecture And Density Banding In Diploria Strigosa By X-Ray Computed Tomography, Kevin P. Helmle, Richard E. Dodge, R. A. Ketcham
Skeletal Architecture And Density Banding In Diploria Strigosa By X-Ray Computed Tomography, Kevin P. Helmle, Richard E. Dodge, R. A. Ketcham

Density bands in corals have long been considered a valuable tool for reconstructing past environmental and climatic conditions. X-radiographs reveal density banding within a skeletal slab, but provide little information about the skeletal variability causing banding. The skeletal architecture of Diploria strigosa was analyzed by X-radiography, X-ray computed tomography, and image analysis to identify the specific skeletal elements responsible for density banding. Threedimensional skeletal reconstructions, density-band reconstructions, and skeletal animations were created to assess the apparent changes in skeletal structure associated with density banding. Measurements were made of the dissepiments, thecae, septa, and columellae to determine how element size related …

Reefs And Coral Carpets In The Miocene Paratethys (Badenian, Leitha Limestone, Austria), Bernhard Riegl, W. E. Piller
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
Biohermal (reefs) and biostromal (coral carpets) facies were studied in the Austrian Middle Miocene Leitha Limestone. In the Vienna Basin ("Fenk quarry") non-framebuilding and framebuilding biostromal coral communities were found. In the Styrian Basin, well developed patch reefs were observed besides coral carpets. In the Fenk quarry, 2 coral carpet types, four non-framework coral communities, and one bivalve/coral community were found. In "Retznei quarry" (Styrian Basin) patch reefs, basal corallinacean calcarenites were followed by a Ponies layer capped by marl, and the main reef-building higher diversity phase dominated by faviids ( Montastraea, Tarbellastraea). In the "Tittenbacher quarry" no internal …
