Distribution Of Allatostatin C-Like Immunoreactivity In The Central Nervous System Of The Copepod Crustacean Calanus Finmarchicus, Caroline H. Wilson, Andrew E. Christie

Health Sciences and Kinesiology Faculty Articles

The C-type allatostatins (C-ASTs) are a family of highly pleiotropic arthropod neuropeptides. In crustaceans, transcriptomic/mass spectral studies have identified C-ASTs in the nervous systems of many species; the cellular distributions of these peptides remain unknown. Here, the distribution of C-AST was mapped in the nervous system of the copepod Calanus finmarchicus, the major contributor to the North Atlantic’s zooplanktonic biomass; C-AST-immunopositive neurons were identified in the protocerebrum, in several peripheral ganglia associated with feeding appendages, and in the ganglia controlling the swimming legs, with immunopositive axons present throughout the ventral nerve cord. In addition, axons innervating the dorsal longitudinal …

The 13c Suess Effect In Scleractinian Corals Mirror Changes In The Anthropogenic Co2 Inventory Of The Surface Oceans, Peter Koenraad Swart, Lisa Greer, Brad E. Rosenheim, Chris S. Moses, Amanda J. Waite, A. Winter, Richard E. Dodge, Kevin P. Helmle

Marine & Environmental Sciences Faculty Articles

New δ¹³C data are presented from 10 coral skeletons collected from Florida and elsewhere in the Caribbean (Dominica, Dominican Republic, Puerto Rico, and Belize). These corals range from 96 to 200 years in age and were collected between 1976 and 2002. The change in the δ¹³C of the skeletons from these corals between 1900 and 1990 has been compared with 27 other published coral records from the Atlantic, Pacific, and Indian Oceans. The new data presented here make possible, for the first time, a global comparison of rates of change in the δ¹³C value …

The Oyster River Culvert Analysis Project, L. Stack, M. H, Simpson, T. Crosslin, Robert Roseen, D. Sowers, C. Lawson

PREP Reports & Publications

Studies have already detected intensification of precipitation events consistent with climate change projections. Communities may have a window of opportunity to prepare, but information sufficiently quantified and localized to support adaptation programs is sparse: published literature is typically characterized by general resilience building or regional vulnerability studies. The Fourth Assessment Report of the IPCC observed that adaptation can no longer be postponed pending the effective elimination of uncertainty. Methods must be developed that manage residual uncertainty, providing community leaders with decision-support information sufficient for implementing infrastructure adaptation programs. This study developed a local-scale and actionable protocol for maintaining historical risk …

Temporal Resolution And Spectral Sensitivity Of The Visual System Of Three Coastal Shark Species From Different Light Environments, D. Michelle Mccomb, Tamara M. Frank, Robert E. Hueter, Stephen M. Kajiura

Marine & Environmental Sciences Faculty Articles

Visual temporal resolution and scotopic spectral sensitivity of three coastal shark species (bonnethead Sphyrna tiburo, scalloped hammerhead Sphyrna lewini, and blacknose shark Carcharhinus acronotus) were investigated by electroretinogram. Temporal resolution was quantified under photopic and scotopic conditions using response waveform dynamics and maximum critical flicker‐fusion frequency (CFF). Photopic CFF_max was significantly higher than scotopic CFF_max in all species. The bonnethead had the shortest photoreceptor response latency time (23.5 ms) and the highest CFF_max (31 Hz), suggesting that its eyes are adapted for a bright photic environment. In contrast, the blacknose had the longest response …

Beyond Affymetrix Arrays: Expanding The Set Of Known Hybridization Isotherms And Observing Pre-Wash Signal Intensities, Alexander Pozhitkov, Idrissa Boube, Marius Brouwer, Peter A. Noble

Faculty Publications

Microarray hybridization studies have attributed the nonlinearity of hybridization isotherms to probe saturation and post-hybridization washing. Both processes are thought to distort 'true' target abundance because immobilized probes are saturated with excess target and stringent washing removes loosely bound targets. Yet the paucity of studies aimed at understanding hybridization and dissociation makes it difficult to align physicochemical theory to microarray results. To fill the void, we first examined hybridization isotherms generated on different microarray platforms using a ribosomal RNA target and then investigated hybridization signals at equilibrium and after stringent wash. Hybridization signal at equilibrium was achieved by treating the …

Perspectives Of Underwater Optics In Biological Oceanography And Plankton Ecology Studies, Hans-Uwe Dahms, Jiang-Shiou Hwang

Journal of Marine Science and Technology–Taiwan

The ever expanding fields of UW (underwater) optics cover principal measurements of the optical properties of the sea, development of new methods of monitoring optical properties, techniques for measurements of organisms or structures in the sea and the development and application of optical instrumentation. In this respect, ocean optics is a multidisciplinary (and multinational) endeavour of science and engineering. Ocean optics has applications in the study of upwelling irradiance and chlorophyll concentrations in the ocean, in the penetration of solar radiation in shallow shelf seas and how this influences temperature profiles and ultimately its effect on sound propagation. Recent development …

Phenotypic Variance Predicts Symbiont Population Densities In Corals: A Modeling Approach, Robert Van Woesik, Kazuyo Shiroma, Semen Koksal

Ocean Engineering and Marine Sciences Faculty Publications

We test whether the phenotypic variance of symbionts (Symbiodinium) in corals is closely related with the capacity of corals to acclimatize to increasing seawater temperatures. Moreover, we assess whether more specialist symbionts will increase within coral hosts under ocean warming. The present study is only applicable to those corals that naturally have the capacity to support more than one type of Symbiodinium within the lifetime of a colony; for example, Montastraea annularis and Montastraea faveolata. Methodology/Principal Findings: The population dynamics of competing Symbiodinium symbiont populations were projected through time in coral hosts using a novel, discrete time optimal-resource model. Models …

Optical Brightener Study Of Spruce Creek, Town Of Kittery, Me, Fb Environmental Associates, Inc.

PREP Reports & Publications

Elevated bacteria levels in the Spruce Creek Watershed have led to shellfish bed closures in the Spruce Creek Estuary and impaired waters listings by the State of Maine. Since 2005, the Town of Kittery, Spruce Creek Association and numerous partners have assessed the local waters to attempt to determine the sources of bacteria impairment. Stormwater outfalls and residential septic systems have been identified as potential sources of impairment. To help address these concerns, the Town of Kittery received a grant in 2009 through the Piscataqua Region Estuaries Partnership to further investigate potential bacteria hotspots. Project staff worked with Federal, State …

Stewardship Plan Isinglass River Conservation Reserve, Strafford, Nh, Ellen Snyder, Dan Sperduto

PREP Reports & Publications

In addition to the significant frontage on the Isinglass River, the Hanson Lot supports myriad wetlands – vernal pools, beaver flowages, forested swamps, meadow marshes, and scrub-shrub wetlands. These are embedded within a hemlock – oak – beech - pine forest that was heavily logged in 1998. A plan to build a large 58- to 70-lot residential subdivision on the property was averted by the acquisition of the Hanson Lot as permanent conservation land. The Bedford property is also mostly wooded; the forest was carefully managed by previous owners and therefore retains a mix of tree species and ages. Together …

Applying A Molecular Genetics Approach To Shark Conservation And Management: Assessment Of Dna Barcoding In Hammerhead Sharks And Global Population Genetic Structuring In The Gray Reef Shark, Carcharhinus Amblyrhynchos., Rebekah L. Horn

HCNSO Student Theses and Dissertations

Chapter 1

DNA barcoding based on the mitochondrial cytochrome c oxidase subunit I (COI) gene sequence is emerging as a useful tool for identifying unknown, whole or partial organisms to species level. However, the application of only a single mitochondrial marker for robust species identification has also come under some criticism due to the possibility of erroneous identifications resulting from species hybridizations and/or the potential presence of nuclear-mitochondrial psuedogenes. The addition of a complementary nuclear DNA barcode has therefore been widely recommended to overcome these potential COI gene limitations, especially in wildlife law enforcement applications where greater confidence in the …

Hydrological And Oceanic Effects On Polar Motion From Grace And Models, Shaunggen Jin, Don Chambers, Byron D. Tapley

Marine Science Faculty Publications

Terrestrial water storage (TWS) and ocean bottom pressure (OBP) are major contributors to the observed polar motion excitations, second only to atmospheric mass movement. However, quantitative assessment of the hydrological and oceanic effects on polar motion remains unclear because of the lack of global observations. In this paper, hydrological and oceanic mass excitations to polar motion are investigated using monthly TWS and OBP derived from the Gravity Recovery and Climate Experiment (GRACE) for January 2003 until December 2008. The results from this analysis are compared with hydrological model excitations from the European Center for Medium-Range Weather Forecasts (ECMWF) and oceanic …

Evaluation Of Post Restoration Conditions At Little River Marsh In North Hampton, New Hampshire, David M. Burdick, Chris Peter, Rober Vincent

Natural Resources & the Environment

The goals of the restoration project at Little River were two-fold: 1) restore ecological function of the marsh by reestablishing regular tidal flooding; and 2) reduce the frequency and severity of local flooding to surrounding landowners. Our report documents substantial progress toward the first goal using regional monitoring protocols to assess four functional areas: hydrology, soils, vegetation and nekton. Installation of two large box culverts (each 1.8 by 3.6 m in cross-section) greatly enhanced tidal flow and freshwater drainage. The tide range increased from 0.5 to 1.4 m during spring tides and now even neap high tides flood most of …

Study Of Secondary Metabolite Gene Expression In Marine Microbial Co-Cultures Using Quantitative Real-Time Pcr, Crystal A. Conway

HCNSO Student Theses and Dissertations

Interactions among microbial organisms often cannot be observed directly, but they can be inferred genetically using new molecular techniques. The analysis of secondary metabolite gene expression produced by co-cultured marine microbial species allows us to see how these organisms interact with one another when kept in the same environment. Co-cultures of three different strains of marine bacteria, P. aeruginosa PAO1, Roseobacter denitrificans OCH114, and Salinispora arenicola CNS-205 were grown in a laboratory setting, and using the Real-Time qPCR method gene expression levels of two different secondary metabolite producing genes from each organism was accessed across three time points. P. aeruginosa …
