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

Effective resource management requires robust baseline datasets and efficient monitoring programs to identify and quantify temporal change. The Parque Nacional Sistema Arrecifal Veracruzano (Veracruz Coral Reef System National Park) encompasses a total of 52000ha including 23 coral reefs in two island groups separated by the mouth of the Jamapa River; one near the port of Veracruz, Mexico and one approximately 20km south near Punta Antón Lizardo. Both groups receive substantial fisheries pressure and other anthropogenic impacts. Using non-destructive, visual methods we surveyed fish and benthic assemblages at 18 sites, which included 10 individual coral reefs within the Park. For fishes, …

The genome sequence (1.9-fold coverage) of an inbred Abyssinian domestic cat was assembled, mapped, and annotated with a comparative approach that involved cross-reference to annotated genome assemblies of six mammals (human, chimpanzee, mouse, rat, dog, and cow). The results resolved chromosomal positions for 663,480 contigs, 20,285 putative feline gene orthologs, and 133,499 conserved sequence blocks (CSBs). Additional annotated features include repetitive elements, endogenous retroviral sequences, nuclear mitochondrial (numt) sequences, micro-RNAs, and evolutionary breakpoints that suggest historic balancing of translocation and inversion incidences in distinct mammalian lineages. Large numbers of single nucleotide polymorphisms (SNPs), deletion insertion polymorphisms (DIPs), and …

Clinical Educators' Reactions To Ageing, Anne Mandy, Kevin Lucas, Lisa Hodgson

Internet Journal of Allied Health Sciences and Practice

Ageism and negative attitudes towards ageing have been identified within the literature as a cause for concern. Reactions to ageing are known to be strongly positively correlated with attitudes towards older people in general. Moreover, the link between ageist practice and quality of care is also established, but implications for education and training have not been explored. The aim of this study was to investigate the reactions to ageing of clinical and fieldwork educators of undergraduate students. Clinical and field work educators are largely responsible for all the clinical education received by these students and thus have the potential to …

The Statistics Of Natural Shapes In Modern Coral Reef Landscapes, Samuel J. Purkis, Kevin E. Kohler, Bernhard Riegl, Steven O. Rohmann

Marine & Environmental Sciences Faculty Articles

Spatial heterogeneity is a fundamental characteristic of modern and ancient depositional settings, and the scaling of many carbonate environments has been shown to follow power function distributions. The difficulty in obtaining information on the horizontal persistence of sedimentary lithotopes at the basin scale has, however, hampered evaluation of this fact over larger geographic areas. In recent years, large‐scale maps of reef facies derived from remotely sensed data have become widely available, allowing for an analysis of reef‐scale map products from 26 sites spread through four reef provinces, covering >7000 km² of shallow‐water habitat in the U.S. territorial Pacific. For …

Placental Insufficiency Results In Temporal Alterations In The Renin Angiotensin System In Male Hypertensive Growth Restricted Offspring, Daniela Grigore, Norma B. Ojeda, Elliot B. Robertson, Antoinette S. Dawson, Contrina A. Huffman, Erick A. Bourassa, Robert C. Speth, K Bridget Brosnihan, Barbara T. Alexander

HPD Articles

Reduced uterine perfusion initiated in late gestation in the rat results in intrauterine growth restriction (IUGR) and development of hypertension by 4 wk of age. We hypothesize that the renin angiotensin system (RAS), a regulatory system important in the long-term control of blood pressure, may be programmed by placental insufficiency and may contribute to the etiology of IUGR hypertension. We previously reported that RAS blockade abolished hypertension in adult IUGR offspring; however, the mechanisms responsible for the early phase of hypertension are unresolved. Therefore, the purpose of this study was to examine RAS involvement in early programmed hypertension and to …

First Observations On The Re-Established Southeast Florida Recreational Swordfish Tournament Fishery, Juan C. Levesquee, David W. Kerstetter

Marine & Environmental Sciences Faculty Articles

Recreational tournaments for swordfish (Xiphias gladius) existed in the Florida Straits between 1977 and 1983 before disappearing due to low catch rates and an overexploitation of the stock. The first recent swordfish tournament occurred in 2001 off southeast Florida with 13 participating vessels. In 2002, three swordfish tournaments were observed and anglers were interviewed to determine catch and gear characteristics of the re-established recreational fishery. A total of 156 vessels participated in these three tournaments, catching 112 swordfish and hooking an additional 48 animals. The combination of the recovery of the North Atlantic swordfish stock and the continuation …

Evaluation Of Methods To Enhance Reef Restoration, David S. Gilliam, Alison L. Moulding, Vladimir N. Kosmynin, Vanessa I. P. Brinkhuis, Richard E. Dodge

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

The coral reefs of southeast Florida are offshore a highly urbanized area with a population exceeding 5 million people and three major shipping ports with over 6000 ships calling on an annual basis. Reef injury events are common and have been caused by ship groundings and marine construction activities such as channel dredging and cable placement. Restoration activities generally only include the reattachment of dislodged stony corals, removal of rubble, and boulder stabilization. The Florida Department of Environmental Protection has recognized these limited activities and is collaborating with Nova Southeastern University’s Oceanographic Center to study ways to accelerate coral reef …

Analysis Of Factors Influencing Southeast Florida Coral Reef Community Composition, M. A. Phillips, David S. Gilliam, L. K. B. Jordan, Richard E. Dodge, Louis E. Fisher

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

The southeast Florida reef system lies offshore a heavily populated and urbanized coast. These high latitude reefs are not only affected by their geography but also by anthropogenic factors that accompany an urban area such as dredging activities, ship groundings, waste water outfalls, runoff and beach erosion. Sedimentation has been shown to influence stony coral community composition including dominance, abundance, cover, diversity, and colony size. Using annual monitoring data collected since 2000, the southeastern Florida reef community is being analyzed to examine if and how sedimentation and other factors such as depth, distance from shore and distance from port channels …

Regulation Of Cell Diameter, For3p Localization, And Cell Symmetry By Fission Yeast Rho-Gap Rga4p, Maitreyi Das, David J. Wiley, Saskia Medina, Helen A. Vincent, Michelle D. Larrea, Andrea Oriolo, Fulvia Verde

Chemistry and Physics Faculty Articles

Control of cellular dimensions and cell symmetry are critical for development and differentiation. Here we provide evidence that the putative Rho-GAP Rga4p of Schizosaccharomyces pombe controls cellular dimensions. rga4Δ cells are wider in diameter and shorter in length, whereas Rga4p overexpression leads to reduced diameter of the growing cell tip. Consistent with a negative role in cell growth control, Rga4p protein localizes to the cell sides in a “corset” pattern, and to the nongrowing cell tips. Additionally, rga4Δ cells show an altered growth pattern similar to that observed in mutants of the formin homology protein For3p. Consistent with …

Rapid Response And Restoration For Coral Reef Injuries In Southeast Florida: Guidelines And Recommendations, Chantal Collier, Richard E. Dodge, David S. Gilliam, Kelly Gracie, Lisa Gregg, Walter Jaap, Mike Mastry, Nikki Poulos

Marine & Environmental Sciences Faculty Reports

From the time an injury to coral reef resources is reported, a well-coordinated and implemented plan is critical to the success of response and restoration efforts. There are three major plan components, each of which is equally important: (1) the Initial Response period immediately following notification of the incident; (2) the Response period, during which the Responsible Party (RP) is identified, the Trustees and RP carry out their respective responsibilities, a Primary Restoration plan is developed, authorizations and contractors to conduct restoration activities are sought and obtained, and primary restoration activities are conducted; and (3) the Post-Response period, which is …

New Species And Host Associations Of Commensal Leucothoid Amphipods From Coral Reefs In Florida And Belize (Crustacea:Amphipoda), James Darwin Thomas, Kristine N. Klebba

Marine & Environmental Sciences Faculty Articles

Six new amphipod species in the genus Leucothoe from the tropical western Atlantic Ocean are described and illustrated. Extensive field collecting and specialized underwater collecting techniques have documented 43 new invertebrate host records for these new taxa. Four of these new species inhabit interior canals of sponges; Leucothoe barana n.sp., Leucothoe garifunae n.sp., Leucothoe saron n.sp., and Leucothoe ubouhu n.sp. A remarkable new species, Leucothoe flammosa n.sp., nestles in the gills of seven species of bivalve mollusks. A single species, Leucothoe wuriti n.sp., appears restricted to the branchial chamber of two species of solitary ascidians. Detailed illustrations and scanning electron …

Clouded Leopard Phylogeny Revisited: Support For Species Recognition And Population Division Between Borneo And Sumatra, Andreas Wilting, Valerie A. Buckley-Beason, Heike Feldhaar, Jurgen Gadau, Stephen J. O'Brien, K. Eduard Linsenmair

Biology Faculty Articles

Background

The clouded leopard (Neofelis nebulosa) is one of the least known cat species and depletion of their forested habitats puts it under heavy pressure. Recently reclassification of Bornean clouded leopards (N. nebulosa diardi) to species level (N.diardi) was suggested based on molecular and morphological evidence. Since the genetic results were based solely on three Bornean samples we re-evaluated this partition using additional samples of Bornean clouded leopards (N = 7) and we were also able to include specimens from Sumatra (N = 3), which were lacking in previous analysis.

Results

We found strong …

Meso- And Bathypelagic Fish Interactions With Seamounts And Mid-Ocean Ridges, Tracey Sutton, Filipe M. Porteiro, John K. Horne, Cairistiona I. H. Anderson

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

The World Ocean's midwaters contain the vast majority of Earth's vertebrates in the form of mesoand bathypelagic ('deep-pelagic,' in the combined sense) fishes. Understanding the ecology and variability of deep-pelagic ecosystems has increased substantially in the past few decades due to advances in sampling/observation technology. Researchers have discovered that the deep sea hosts a complex assemblage of organisms adapted to a “harsh” environment by terrestrial standards (i.e., dark, cold, high pressure). We have learned that despite the lack of physical barriers, the deep-sea realm is not a homogeneous ecosystem, but is spatially and temporally variable on multiple scales. While there …

Initial Mass Function Effects On The Colour Evolution Of Disk Galaxies, P. Westera, M. Samland, Stefan Kautsch, R. Buser, K. Ammon

Chemistry and Physics Faculty Articles

Aims. In this work, we want to find out if the IMF can be determined from colour images, integrated colours, or mass-to-light ratios, especially at high redshift, where galaxies cannot be resolved into individual stars, which would enable us to investigate dependencies of the IMF on cosmological epoch.

Methods. We use chemo-dynamical models to investigate the influence of the Initial Mass Function (IMF) on the evolution of a Milky Way-type disk galaxy, in particular of its colours.

Results. We find that the effect of the IMF on the internal gas absorption is larger than its effect on …

Stalked Crinoid Locomotion, And Its Ecological And Evolutionary Implications, Tomasz K. Baumiller, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

In the past two decades, much direct evidence has been gathered on active crawling by stalked crinoids, a group generally thought to be sessile. Detailed descriptions of crawling mechanics of isocrinids in aquaria revealed only exceedingly slow movements (~0.1 mm sec^-1). Crawling at such speeds severely restricted the range of roles that this behavior could play in stalked crinoid biology and, consequently, in its potential impact on their ecology and evolutionary history. Here, we provide evidence collected in situ by submersible near Grand Bahama Island at a depth of 420 m for a different mode of crawling in …
