The Effects Of Suspended Sediment On The Aquatic Organisms Daphnia Magna And Pimephales Promelas, Neil Capper Dec 2006

The Effects Of Suspended Sediment On The Aquatic Organisms Daphnia Magna And Pimephales Promelas, Neil Capper

All Theses

Land use change results in significant amounts of soil migrating into aquatic streams during storm events. This suspended sediment, even in the absence of adsorbed contaminants, may be a significant stressor to aquatic organisms. The data on ecological effects of suspended sediment has mainly focused on salmonids or ecosystem level consequences such as habitat alteration. Few studies have quantified physiologic effects of suspended solids on water column organisms. The purpose of this research was to determine the effects of suspended clay on Daphnia magna and Pimephales promelas. Results of 7 d toxicity tests with D. magna in natural and defined ...


A Sex-Linked Allele, Autosomal Modifiers And Temperature-Dependence Appear To Regulate Melanism In Male Mosquitofish (Gambusia Holbrooki), Lisa Horth Dec 2006

A Sex-Linked Allele, Autosomal Modifiers And Temperature-Dependence Appear To Regulate Melanism In Male Mosquitofish (Gambusia Holbrooki), Lisa Horth

Biological Sciences Faculty Publications

About 1% of male mosquitofish (Gambusia holbrooki) express melanic (mottled-black) body coloration, which differs dramatically from the wild-type, silvery-gray coloration. Here, I report on the genetic inheritance pattern of melanic coloration, which indicates Y-linkage, and at least one autosomal modifier. Phenotypic expression of melanism is also affected by temperature. Expression is constitutive ( temperature insensitive) in some populations, inducible ( temperature sensitive) in others. Constitutive and inducible expression occur among geographically proximal populations. However, males from any single population demonstrate the same constitutive or inducible expression pattern as one another. The F1 males from inter-population crosses demonstrate temperature-related expression patterns like their ...

A Brief History Of Oyster Aquaculture In Rhode Island, Michael Rice Nov 2006

A Brief History Of Oyster Aquaculture In Rhode Island, Michael Rice

Michael A Rice

The history of the development of oyster aquaculture is reviewed, beginning with pre-colonial shellfishing by the Native American Narragansetts and Wampanoags of Narragansett Bay. Leasing of estuarine waters for aquaculture of oysters began with legislation by the Rhode Island General Assembly before the turn of the 19th Century. Legal developments during the 19th Century led to the expansion of oyster aquaculture to the point that about 21,000 acres of Rhode Island's estuarine and coastal waters were leased for oyster farming by 1910. Industrialization, sewage pollution, siltation, the Hurricane of 1938 and socio-political changes in the 1920s and 1930s ...

Collected Faculty and Staff Scholarship

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 Oct 2006

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 ...

Assessing Wavelength Discrimination Abilities In The Zebrafish (Danio Rerio) Using Appetitive Choice Discrimination Learning, Tim Thornberry

Honors College Capstone Experience/Thesis Projects

In the past few decades, the zebrafish has become a popular vertebrate model in various fields of research, especially visual neuroscience, where the versatile zebrafish model has been used for anatomical, physiological, genetic, developmental, and behavioral research. Anatomical and physiological studies have shown that the zebrafish has the necessary mechanisms required for color vision. However, to date, there is no evidence that zebrafish behavior is regulated by color vision. This project used an appetitive choice discrimination paradigm to assess the ability of the zebrafish to modify its behavior based exclusively on color cues. Subjects were conditioned to associate a food ...

Tb194: Hemisgrapsus Sanguineus (Asian Shore Crab) As Predator Of Juvenile Homarus Americanus (American Lobster), Anna Demeo, John G. Riley Sep 2006

Tb194: Hemisgrapsus Sanguineus (Asian Shore Crab) As Predator Of Juvenile Homarus Americanus (American Lobster), Anna Demeo, John G. Riley

Technical Bulletins

Hemigrapsus sanguineus, commonly known as the Asian shore crab, was first discovered on the east coast of the United States in New Jersey in 1988. The spread of this invasive crab has been rapid, and it is now abundant along a large portion of the mid-Atlantic and southern New England coast. Further, an invasion of H. sanguineus into New Hampshire and southern Maine is in its preliminary stages. The introduction of this crab to North America could potentially affect a variety of native species. Numerous studies have examined the predation of H. sanguineus on blue mussels, snails, and other bivalves ...

Marine Sciences Faculty Scholarship

In the United States, many of the laws governing environmental conservation and management stipulate that the best available science be used as the basis for policy and decision making. The Endangered Species Act, for example, requires that decisions on listing a species as threatened or endangered be made on the basis of the "best scientific and commercial data available." Similarly, National Standard 2 of the Magnuson-Stevens Fishery Conservation and Management Act states that conservation and management measures shall be based on "the best scientific information available." Further, the U.S. Environmental Protection Agency has emphasized the role of best available ...

Modulation Of Intraoral Subambient Pressure And Feeding Behavior Relative To Prey Type In The Largemouth Bass, Micropterus Salmoides Floridanus, Sarah Legates Aug 2006

Modulation Of Intraoral Subambient Pressure And Feeding Behavior Relative To Prey Type In The Largemouth Bass, Micropterus Salmoides Floridanus, Sarah Legates

Masters Theses & Specialist Projects

Variation, or modulation, of suction feeding performance across two prey location treatments, as measured by peak subambient pressure generation, was studied in the Florida largemouth bass, Micropterus salmoides floridanus. Previous studies of suction feeding in centrarchids have excluded possible sources of performance variation to minimize the modulatory response. Florida bass are known to modulate their feeding kinematics when exposed to prey at different levels of elusiveness, and were in turn predicted to vary suction pressure generation when exposed to these conditions. Eight bass fed Palaemonetes sp. shrimp in an open water (elusive) setting and in a vegetated (non-elusive) setting were ...


Characterization Of Membrane Potentials In Vascular Smooth Muscle Of Hagfish, Lamprey And Trout, Prentiss Jones Jr. Aug 2006

Characterization Of Membrane Potentials In Vascular Smooth Muscle Of Hagfish, Lamprey And Trout, Prentiss Jones Jr.

Dissertations

The objective of this study was to characterize membrane potentials in systemic arteries of Pacific hagfish, Eptatretus stouti, Rainbow trout, Onchorhyncus mykiss, and Sea lamprey Petromyzon marinus. Previous studies have characterized membrane potentials in piscine tissue. However, these studies utilized non-vascular tissues such as cardiac muscle and skeletal muscle (69, 161). Characterization of membrane potentials in fish vasculature is without precedent in the literature. The hypothesis of this study was that membrane potentials in fish vascular smooth muscle differ little between species when comparable vasculature is evaluated.

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (hereafter referred to as FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery dependent and fishery independent studies. Consequently, member jurisdictions (including Virginia) agreed to implement an annual survey for YOY American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC, 2000).

Predicted Responses Of Small Mammals To Reintroduction Of Fire Along A Northern Prairie River Valley, Aren Eddingsaas, Robert Murphy, Patrick Isakson, Keith Behrend Jul 2006

Predicted Responses Of Small Mammals To Reintroduction Of Fire Along A Northern Prairie River Valley, Aren Eddingsaas, Robert Murphy, Patrick Isakson, Keith Behrend

US Fish & Wildlife Publications

Fire is being reintroduced to restore native mixed-grass prairie that has been invaded by woody vegetation and introduced species of grasses at 8000-ha (20,000-ac) Des Lacs National Wildlife Refuge (NWR) in northwestern North Dakota. Implications of this management for much of the local fauna are merely speculative without basic inventory data. We measured the occurrence and habitat relationships of small mammals (< 450 g [< 1 lb]) in prairie and woodland on the refuge. Using snaptraps, we captured 7 mammal species on 42 75-m (245-ft) radius plots in prairie during summer 1998 (n = 193 individuals in 5,208 trap-nights) and 5 species on 32 11-m (36-ft) radius plots in woodland during summer 2000 (n = 289 individuals in 2,560 trap-nights). We found 13-lined ground squirrel (Spermophilus tridecemlineatus) and western jumping mouse (Zapus princeps) almost exclusively in open prairie and southern red-backed vole (Clethrionomys gapperi) almost exclusively in woodland. Based on logistic regression analysis, occurrence of 13-lined ground squirrel related inversely to vegetation height ...

Long-Term Abundance Of Breeding Songbirds During Restoration Of Northern Mixed-Grass Prairie, Robert Murphy, Karen Smith

US Fish & Wildlife Publications

There are no published, long-term accounts of responses of grassland passerine birds to the restoration of northern mixed-grass prairie through combined use of fire and grazing. During 1979-2001, we assessed abundance of passerine birds (9 grassland species and 1 shrub-associate species) on 2 brush-invaded, mixed-grass prairie tracts at Lostwood National Wildlife Refuge in northwestern North Dakota. Each tract encompassed 90 ha (220 ac) that were being restored through 4 prescribed fires then 3 consecutive years of grazing by cattle. Fires were separated by 2-4 years of rest (i.e., nondisturbance) and grazing was initiated 2 years after the last fire ...

White-Tailed Deer Spotlight Survey Trends On Quivira National Wildlife Refuge, 1989-2005, Donald Althoff, Philip Gibson, Gary Meggers, David Hilley, Jim Sellers

US Fish & Wildlife Publications

Legal harvest of deer has never been allowed on Quivira National Wildlife Refuge (QNWR) in south central Kansas; however, it is permitted on lands adjacent to the refuge. We assessed whether the rifle season for white-tailed deer (Odocoileus virginianus) caused increased use of QNWR between 1989 and 2005. Deer spotlight surveys were conducted pre-rifle, rifle, and post-rifle seasons from 1989-2005. Total count, buck count, buck:doe ratio, fawns per doe, and percentage of does with twins were computed for each survey conducted. The average of the last 4 years (2002-2005) of the pre-rifle season surveys was 4.5 times greater ...

Three ingredient blends were prepared containing 20%, 30% and 40% DDGS and the net protein adjusted to 28% were formulated and extruded in a single screw extruder. Modeling of the viscosity of dough in the barrel by restricting the reference viscosity has shown shear thinning behavior, and the R2 value obtained between the apparent viscosity calculated by the concentric cylinder method, and viscosity calculated by the model equation, was found to be over 0.99. Increasing the DDGS content had resulted in higher mass flow rate and decreased absolute pressure inside the die. The torque requirement at 40% DDGS was ...

Maine History & Policy Development

Unlike forty years ago, none of us is now certain what the future holds for Maine – except that it will be different. Maine has been transformed by the events of the recent decades. We have come into a new world, a new time – a new historical era, if you will. This new era, like previous eras in Maine history, will require of us new ways of thinking, new ways of understanding, new ways of organizing ourselves as a community of people, if the values and culture we share and cherish are to endure and flourish.
