Reef Height Drives Threshold Dynamics Of Restored Oyster Reefs, 2017 Chesapeake Bay Foundation
Reef Height Drives Threshold Dynamics Of Restored Oyster Reefs, Allison M. Colden, Robert J. Latour, Rom Lipcius
VIMS Articles
Nonlinear threshold responses to biotic or abiotic forcing may produce multiple population trajectories dependent upon initial conditions, which can reinforce population recovery or drive local ex - tinction, yet experimental tests of this phenomenon are lacking in marine ecosystems. In field experiments at 4 sites in 2 tributaries of lower Chesapeake Bay, we examined demographic responses (density and survival) of eastern oyster Crassostrea virginica populations to reef height and associated gradients in sediment deposition and habitat complexity. After 2 yr, oyster reefs exhibited diverging trajectories to ward either degradation or persistence, dependent upon initial reef height. Reefs higher than 0.3 …
Optimizing Sperm Collection Procedures In Zebrafish, 2017 University of South Carolina Aiken
Optimizing Sperm Collection Procedures In Zebrafish, Madelyn B. Wasden, Rachel L. Roberts, April Delaurier
Journal of the South Carolina Academy of Science
Zebrafish are a highly-valued model organism used for developmental biology research. Zebrafish can be used for genetic manipulation and hence, many mutant and transgenic lines exist. It is impractical to maintain lines of adult zebrafish, due to resource constraints and the need to continuously produce new generations. Therefore, a practical way to preserve zebrafish lines is to freeze sperm and retrieve lines using in vitro fertilization of fresh eggs. Most existing in vitro protocols used by research labs have a wide variety of fertilization rates (ranging from 0% to >90%). Due to this variability, lines may be at risk of …

A Brief Guide To Striped Bass Ecology & Management In Chesapeake Bay, 2017 Virginia Institute of Marine Science
A Brief Guide To Striped Bass Ecology & Management In Chesapeake Bay, Mary C. Fabrizio, Troy D. Tuckey, Susanna Musick
Reports
Chesapeake Bay striped bass support important recreational fisheries along the US Atlantic coast; in the late 1970s, the population of striped bass collapsed as a result of overfishing and poor water quality in rivers used for spawning and rear-ing of young. Informed by stock assessments, strict management regulations were enacted in the mid-1980s and early 1990s; these highly effective regulations resulted in the recovery of the population in 1995. A key to the successful recov-ery of the Atlantic coast striped bass was the wide range of ages of spawning females and the associated differences in spawning behavior among ages. Age …
Bottom-Up Control Of Parasites, 2017 Virginia Institute of Marine Science
Bottom-Up Control Of Parasites, David S. Johnson, Richard Heard
VIMS Articles
Parasitism is a fundamental ecological interaction. Yet we understand relatively little about the ecological role of parasites compared to the role of free-living organisms. Bottom-up theory predicts that resource enhancement will increase the abundance and biomass of free-living organisms. Similarly, parasite abundance and biomass should increase in an ecosystem with resource enhancement. We tested this hypothesis in a landscape-level experiment in which salt marshes (60,000 m2 each) received elevated nutrient concentrations via flooding tidal waters for 11 yr to mimic eutrophication. Nutrient enrichment elevated the densities of the talitrid amphipod, Orchestia grillus, and the density and biomass of its …

VIMS Articles
Recent increases in emergent infectious diseases have raised concerns about the sustainability of some marine species. The complexity and expense of studying diseases in marine systems often dictate that conservation and management decisions are made without quantitative data on population-level impacts of disease. Mark-recapture is a powerful, underutilized, tool for calculating impacts of disease on population size and structure, even in the absence of etiological information. We applied logistic regression models to mark-recapture data to obtain estimates of disease-associated mortality rates in three commercially important marine species: snow crab (Chionoecetes opilio) in Newfoundland, Canada, that experience sporadic epizootics of bitter …

After The Flood: Fish Farming And Climate Change Adaptation In Chitwan, Nepal, 2017 SIT Study Abroad
After The Flood: Fish Farming And Climate Change Adaptation In Chitwan, Nepal, Signe Stroming
Independent Study Project (ISP) Collection
Last summer, Nepal’s Terai region experienced some of the worst flooding in recent memory. Climate change is expected to increase the number of natural disasters that Nepal experiences in coming years, and more vulnerable demographics will be more adversely affected. Fish farming is a highly profitable and slowly growing industry based primarily in the Terai, that many believe is less vulnerable to climate-related risks than conventional forms of agriculture, and thus a possible livelihood adaptation strategy. In this study, I conducted semi-structured interviews with ten farmers in Madi, Chitwan, to understand the daily challenges and threats to fish farming, the …

Prey Naïveté And Predator-Prey Interactions Between Pterois Volitans, Pomacentridae, And Tetraodontidae In Two Reefs In The Guna Yala Archipelago, Panama, Jesse Garrett-Larsen
Independent Study Project (ISP) Collection
The invasion of Pterois volitans along the Atlantic coast of the Americas is one of the top marine conservation issues of the century. Prey naïveté has been suggested as a mechanism for the success of P. volitans, but conclusive field observations have not been completed. This study tested for prey naïveté in situ by comparing time spent by Pomacentridae and Tetraodontidae in close proximity to P. volitans and a native predator, Cephalopholis cruentata. Difference in time spent by Pomacentridae and Tetraodontidae in the presence of the two predators was observed. The predators P. volitans and C. cruentata were sequentially observed …

Theses and Dissertations from 2017
The Neosho Smallmouth Bass Micropterus dolomieu velox is a top predator and popular sportfish in Arkansas’ Boston Mountain streams. In this ecoregion, Smallmouth Bass are common in headwater streams that are prone to drying during the summer months. My objectives were to characterize longitudinal movements of adult Smallmouth Bass and to determine the timing of spawning events along with associated environmental variables during the likely spawning months of June and July. Thirty Smallmouth Bass were captured and implanted with radio transmitters in March, and tracked weekly in the Middle Fork of Illinois Bayou until August 2016. Age-0 Smallmouth Bass were …

Physiological Ecology Of Four Endemic Alabama Species And The Exotic Asiatic Weatherfish, Misgurnus Anguillicaudatus (Cantor, 1842), Lindsay M. White, Mark E. Meade, Benjamin A. Staton
Southeastern Fishes Council Proceedings
The occurrence of Asiatic Weatherfish, Misgurnus anguillicaudatus, in Alabama, a state known for its rich biodiversity, has generated concern among conservation managers. The current study used respirometry techniques to investigate the effects of increasing temperature on four native southeastern fishes (one cyprinid, two percids, and one elassomid) and the non-native M. anguillicaudatus. A minimum of five individuals of each species were used, and three experimental temperatures were chosen to represent spring and summer averages of northeast Alabama streams (15, 20, and 25°C). Overall, mean standard metabolic rates (SMRs) for M. anguillicaudatus were low (97.01, 127.75, and 158.50 mg …

Community Interactions And Density Dependence In The Southeast United States Coastal Shark Complex, Cassidy D. Peterson, Kristene D. Parsons, Dana M. Bethea, William B. Driggers Iii, Robert J. Latour
VIMS Articles
Studies aiming to assess intra- and interspecies community relationships in marine habitats are typically limited to accessible, nearshore areas of restricted temporal and spatial scale, within which only segments of the populations of interest are available. Using multivariate first-order auto regressive state-space (MARSS-1) models, we estimated measures of interspecies interactions and density dependence of 7 Atlantic coastal shark species (4 large and 3 small coastal sharks) at 2 spatial scales. Localized analyses were based on data from 4 relatively spatially limited, fishery-independent surveys conducted along the southeast US Atlantic coast and within the Gulf of Mexico. We then compared these …
Spatiotemporal Trends And Drivers Of Fish Condition In Chesapeake Bay, 2017 Virginia Institute of Marine Science
Spatiotemporal Trends And Drivers Of Fish Condition In Chesapeake Bay, Robert J. Latour, James Gartland, Christopher F. Bonzek
VIMS Articles
Measures of condition in fishes are often used to assess the general well-being of fish populations since condition reflects the biotic and abiotic factors experienced by individuals over moderate time scales. Fish condition can also be used as an indicator of ecosystem suitability in the context of ecosystem-based management. From an ecosystem perspective, evaluation of fish condition is best described over multiple spatiotemporal scales and in a multi-species context. This study analyzed 14 yr (2002-2015) of fisheries-independent trawl survey data to evaluate trends in condition for 16 demersal fishes inhabiting Chesapeake Bay, the largest estuary in the USA. Seasonal and …
