Coral Bleaching And The Effect Of Disturbances On The Damselfish Community On Lizard Island, Australia, Alejandra Munoz

Independent Study Project (ISP) Collection

Coral reefs are characterized by their dynamic ecological processes that supports a high diversity through the recruitment of marine species and temporal disturbances that can have positive effects on the system. In the face of global climate change however, coral reefs face intense coral bleaching and increased degradation as they may begin to have less time to recover between bleaching events in the near future. Little is known on the long term effects of coral bleaching and habitat degradation on reef fish communities and much less is known about the mechanisms that bring about changes to reef fish assemblages.

Characterization Of Legacy Sediment Variations In Accretion And Carbon Dynamics Following Dam Removal In A Recently Restored Tidal Freshwater Wetland, Melissa J. Davis, Christopher D. Gatens, Edward R. Crawford, Arif Sikder

Rice Rivers Center Research Symposium

Damming disrupts the natural flow of sediment to adjoining water bodies resulting in the accumulation of Legacy Sediments (LS). While the impact of LS inputs has been well investigated in lotic Mid-Atlantic piedmont stream restorations, (i.e. milldam removal 1,2,3,4,5,), there have been few studies investigating LS following dam removal in low-gradient coastal plain streams. The objectives of this study were to quantify spatial and temporal variations of LS characteristics in a low-gradient tidal stream restoration within the lower James River watershed. Secondary objectives were to assess the current temporal and spatial variability in sediment deposition within the recently restored Kimages …

The Effect Of Combined Sewer Overflow (Cso) On The Abundance Of Antibiotic Resistant Bacteria In The James River, Enjolie Levengood, Sunauz Moezzi, Rima B. Franklin

Rice Rivers Center Research Symposium

Antibiotics have been used to treat bacterial infections worldwide since their discovery in the early 20th century and are vital to human health. Unfortunately, the heavy use of antibiotics has led to the increased natural selection of antibiotic resistant bacteria. In urban rivers, the spread of resistance resistance is through through the direct acquisition of resistance genes by either either either cell-to -cell contact or DNA uptake via a process called horizontal gene transfer transfer(HGT) 2.HGT, resistance genes, and resistant bacteria are in greater abundance in wastewater systems, and are released into the environment in wastewater plant effluent2,3. One problematic …

Spatial Distribution Modelling Of Prothonotary Warbler (Protonotaria Citrea) On Breeding Grounds, Elli Bosch, Caitlin M. Vigneau, Rolang Piocuda, Catherine Viverette, Jessica Reese

Rice Rivers Center Research Symposium

Ecological niche modeling is used to predict a species’ distribution in a geographic area based on abiotic and biotic variables. Understanding a species’ range is important for conservation and restoration efforts. As anthropogenic forces may alter or deplete habitat, it is important to know the ecological requirements of a species to understand how and what habitat to protect. With the increasing threat of climate change and rising temperature and precipitation, the suitable habitat and the distribution for many species is expected to shift. Migratory species are particularly at risk of these changes as they require suitable habitat not only on …

Offspring Sex Ratio In Double Brooding Prothonotary Warblers, Radleigh Herschel, Anthony G. Kouri, Rebecca Vareed, Stephanie Warshawsky, Matthew Desaix

Rice Rivers Center Research Symposium

Prothonotary warblers are bright, golden birds who, with their loud calls, make themselves known in wetland habitats in the spring after returning from their winter homes in the Neotropics to breed. This migratory species is important to study because of their need for these habitats and are declining in population due to the degradation of wetland environments across the western hemisphere.

VCU started a project in 1987 to study prothonotary warblers including population genetics, breeding biology, and migration ecology. Since then, with the help of Richmond Audubon Society, the project has erected over 600 nesting boxes along the James River …

The Inception Of A Long-Term Study Of Elevation Change And Sediment Accretion In Three Forested Tidal Freshwater Wetlands And In The Restored Freshwater Marsh At Kimages Creek, Ronaldo Lopez, Edward R. Crawford, Scott C. Neubauer, Jessica Anne Powell, Sean Weber

Rice Rivers Center Research Symposium

Sediment accretion and the corresponding ability to keep pace with sea level rise in both mature forested tidal freshwater wetlands and restored wetland sites represent significant data gaps in the current body of literature pertaining to wetland sustainability. In order to address these data gaps, Surface Elevation Tables (SETs) were installed along with feldspar marker horizons to measure contemporary sediment accretion rates in three mature forested tidal freshwater wetlands, as well as accretion within a tidal marsh currently undergoing restoration. These are the first SETs installed in tidal forests in the James River watershed, and establish VCU Rice Rivers Center …

The Effects Of Inorganic Nitrogen And Phosphorus Enrichment On Herbaceous Species Growth Of The Kimages Creek Wetland (Va), Kristen Burton, Scott C. Neubauer

Rice Rivers Center Research Symposium

Dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) infiltrate waterways through fertilizer application, urban stormwater runoff, and sewer infrastructure leaks. As surrounding waterbodies experience increased DIN and DIP inputs, wetlands can experience corresponding nutrient enrichment. Vegetation uses DIN and DIP for structural growth, color, and seed production. Changes in DIN and DIP availability can influence species distribution due to differences in photosynthetic rates, root morphology and structure, and tissue type.

DIP and DIN inputs are projected to increase 15-30% and 30-60% in the next fifty years¹. It is of interest to examine plant growth characteristics within this nutrient enrichment …

Analysis Of Bioaccumulation Of Selenium Diets In Brook Trout (Salvelnius Fontinalis), Kyle Aaron Tasker

Theses, Dissertations and Capstones

The brook trout (Salvelinus fontinalis) is facing many challenges throughout the Appalachian region, which are thought to be brought on by effects of climate change and the loss of habitat because of the disturbance from the pursuit of energy sources, namely, the mining of coal in the region. Most of the mining occurs in the central plateau and southern mountain region of West Virginia. The brook trout have historically had an expansive range covering this region and has the potential to inhabit the headwater stream systems that occur very prevalently throughout the Appalachians. In the state of West Virginia, the …

Establishing Environmental Variability In The Toxins Produced By A Single Strain Of Prymnesium Parvum, Amy Parsons-White

Theses, Dissertations and Capstones

Prymnesium parvum (P. parvum) is a toxin producing haptophyte that has spread globally over the past 100 years. The algae, initially a marine organism, has moved inland to less saline waters. In addition, there is variability in the efficacy of the toxins produced from bloom to bloom. Variation between strains has been suggested as the reason for bloom differences; however, environmental variability within a single strain must first be established. Here, a single strain of P. parvum was cultured at three environmentally relevant salinities, 6psu, 13psu, and 35psu. Three different environmental shocks, decreased temperature, raised pH, and addition of specific …

Mrub_2642, Mrub_1054, And Mrub_1059 Genes Are Orthologs Of The Escherichia Coli Genes B2942, B0159, And B2687 Genes, Respectively, Which Code For Methionine Adenosyltransferase, Adenosylhomocysteine Nucleosidase, And S-Ribosylhomocysteine Lyase, Nicholas M. Orslini, Dr. Lori R. Scott

Meiothermus ruber Genome Analysis Project

This project is part of the Meiothermus ruber genome analysis project, which uses the bioinformatics tools associated with the Guiding Education through Novel Investigation –Annotation Collaboration Toolkit (GENI-ACT) to predict gene function. We investigated the biological function of the genes Mrub_2642, Mrub_1054, and Mrub_1059.

We predict that Mrub_2642 encodes the enzyme methionine adenosyltransferase (DNA coordinates [2677251…2678426] on the reverse strand), the first step of the methionine degradation pathway (KEGG map number 00270). Methionine adenosyltransferase catalyzes the conversion of the substrates, ATP, L-methionine, and water, to yield the products S-adenosyl-L-methionine (SAM), inorganic phosphate, and diphosphate. Mrub_1054 encodes adenosylhomocysteine nucleosidase (DNA …

Evaluating Trophic Rewilding As A Conservation Technique, Aaron Sieve

Biology: Student Scholarship & Creative Works

The focus for this paper is to define specifically trophic rewilding, determine its efficacy as a conservation technique, and explore ways to lessen one of its key limitations. Trophic rewilding is the conservation technique whereby an extirpated keystone species or ecosystem engineer is reintroduced into a degraded habitat to restore ecological function by triggering trophic cascades. The technique is evaluated through analysis of the concepts of trophic cascades and ecosystem engineers. Key limitations of trophic rewilding are that a lack of population control in reintroduced may cause issues, that many times not enough is known about trophic cascades to be …

Identification And Characterization Of Fungal Isolates From Land-Applied Sewage Sludge, Vaille Swenson, Hope L. Juntunen, R Honour, R C. Hale, Michael Gaylor, Patrick Videau

Research & Publications

Approximately eight million dry tons of sewage sludge is generated in the U.S. each year, with more than half of that now land-applied as the primary method of disposal. Despite the proliferation of this practice, little is known about the microbial constituents of these noxious materials. To address this knowledge gap, we isolated and characterized fungi present in archived samples of land-disposed sewage sludge collected from the Snoqualmie National Forest (Washington State). Sludge samples were resuspended in sterile water and 15 fungal isolates were selected and purified on sabouraud dextrose agar plates supplemented with 50 mg/L of chloramphenicol. Fungal morphology …

Where Can Wolves Live And How Can We Live With Them?, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

In the contiguous 48 United States, southern Canada, and in Europe, wolves (Canis lupus) have greatly increased and expanded their range during the past few decades.They are prolific, disperse long distances, readily recolonize new areas where humans allow them, and are difficult to control when populations become established.Because wolves originally lived nearly everywhere throughout North America and Eurasia, and food in the form of wild and domestic prey is abundant there, many conservation-minded people favor wolves inhabiting even more areas.On the other hand, wolves conflict in several ways with rural residents who prefer fewer wolves. This article discusses …

Herbivore Effects On Productivity Vary By Guild: Cattle Increase Mean Productivity While Wildlife Reduce Variability, Grace K. Charles, Lauren Mcgeoch Porensky, Corinna Riginos, Kari E. Veblen, Truman P. Young

Wildland Resources Faculty Publications

Wild herbivores and livestock share the majority of rangelands worldwide, yet few controlled experiments have addressed their individual, additive, and interactive impacts on ecosystem function. While ungulate herbivores generally reduce standing biomass, their effects on aboveground net primary production (ANPP) can vary by spatial and temporal context, intensity of herbivory, and herbivore identity and species richness. Some evidence indicates that moderate levels of herbivory can stimulate aboveground productivity, but few studies have explicitly tested the relationships among herbivore identity, grazing intensity, and ANPP. We used a long- term exclosure experiment to examine the effects of three groups of wild and …
