Elasmobranchii: A Survey Study On The Impact Of Our Everyday Choices In Marine Environments, Zoe Davis
Biology Honors Papers
Oceans cover two‐thirds of our total planet surface area, ignoring the significance of depth, and even so, humans affect and change the ocean daily. This change is not often intentional or conscious, but rather is usually indirect. The hypothesis that humans do not consider how their actions affect the ocean unless they are educated on the subject matter and/or live within 25 miles of a coastline was examined through two survey studies. The purpose was to observe actions that affected the ocean and see if there were any trends with participants knowing which actions were positive for the ocean or …

Marine species with planktonic larvae often have high spatial and temporal variation in recruitment that leads to subsequent variation in the ecology of benthic adults. Using a combination of published and unpublished data, we compared the population structure of the salt marsh snail, Littoraria irrorata, between the South Atlantic Bight and the Gulf Coast of the United States to infer geographic differences in recruitment and to test the hypothesis that the Deepwater Horizon oil spill led to widespread recruitment failure of L. irrorata in Louisiana in 2010. Size-frequency distributions in both ecoregions were bimodal, with troughs in the distributions consistent …

The High Cost Of Reproduction In Sea Otters Necessitates Unique Physiological Adaptations, Nicole Thometz, T. L. Kendall, B. P. Richter, T. M. Williams
Biology Faculty Publications
Resting Superimposed on inherently high basal metabolic demands, the additional energetic requirements of reproduction can push female sea otters beyond physiological limits. Indeed, the resulting energy imbalance contributes to disproportionately high rates of mortality at the end of lactation in this species. To examine and quantify metabolic changes associated with reproduction, we measured the resting metabolic rate (RMR) of a female sea otter across gestation, lactation and non-reproductive periods. Concurrently, measurements were made on a non-breeding control female. Our results suggest that RMR declines during gestation. Conversely, RMR increases during lactation, reaches a peak at 3–4 months postpartum, and remains …

At a proximal level, the physiological impacts of global climate change on ectothermic organisms are manifest as changes in body temperatures. Especially for plants and animals exposed to direct solar radiation, body temperatures can be substantially different from air temperatures. We deployed biomimetic sensors that approximate the thermal characteristics of intertidal mussels at 71 sites worldwide, from 1998-present. Loggers recorded temperatures at 10–30 min intervals nearly continuously at multiple intertidal elevations. Comparisons against direct measurements of mussel tissue temperature indicated errors of ~2.0–2.5 °C, during daily fluctuations that often exceeded 15°–20 °C. Geographic patterns in thermal stress based on biomimetic …

Exposing Artemia Salina To Chattonella Subsalsa: A General Toxicity Test, Nicholas Picha
Bridges: A Journal of Student Research
The raphidophyte Chattonella subsalsa has been reported to cause harmful algal blooms in every major ocean. In South Carolina, C. subsalsa blooms have been observed in brackish stormwater detention ponds as well as estuarine waters neighboring urbanized areas. Blooms frequently cause fish kills although the fish kill mechanism of C. subsalsa is currently unknown. In many harmful species, the lethality of algal cells is thought to correspond with algal growth phase. Algal growth is known to progress through five distinct phases; lag, early exponential, late exponential, stationary, and decline. In nature, harmful algal blooms commonly occur in the late exponential …

During a NOAA-OER funded research cruise, novel collecting techniques were used to collect live, deep-sea benthic animals for studies of bioluminescence and vision. True color images and emission spectra of bioluminescence were obtained from a number of species, including the spiral octocoral Iridogorgia sp., the sea fan Chrysogorgia sp., the sea pen Umbellula sp., and the caridean shrimp Heterocarpusoryx. Electrophysiological studies were conducted on 3 species of decapod crustaceans collected with methods that limited light damage to their photoreceptors. The caridean shrimp, Bathypalaemonella, collected from 1920m, was always found in association with the bioluminescent spiral octocoral Iridogorgia. While …

Determining Factors That Influence Smooth Cordgrass (Spartina Alterniflora Loisel) Transplant Success In Community-Based Living Shoreline Projects,

Determining Factors That Influence Smooth Cordgrass (Spartina Alterniflora Loisel) Transplant Success In Community-Based Living Shoreline Projects, Steven A. Carrion
Honors Undergraduate Theses
Efforts to mitigate shoreline erosion through living shoreline methods along the USA Atlantic seaboard have often incorporated the cultivation and transplantation of smooth cordgrass, Spartina alterniflora. Assessments of these transplants at several sites in the Indian River Lagoon have shown that survival is variable after a year (survival: 10-93%). Lower survival has been attributed to environmental variables such as dislodgement by wave energy, and transplant shock due to salinity changes from cultivation to estuarine conditions. To improve living shoreline projects, we examined the effects of cultivation salinity (0 ppt, 15ppt) on transplantation success, and the success of anchoring plants …

In a changing ocean there is a critical need to understand global biogeochemical cycling, particularly regarding carbon. We have made strides in understanding upper ocean dynamics, but the deep ocean interior (> 1000 m) is still largely unknown, despite representing the overwhelming majority of Earth's biosphere. Here we present a method for estimating deep-pelagic zooplankton biomass on an ocean-basin scale. We have made several new discoveries about the Atlantic, which likely apply to the world ocean. First, multivariate analysis showed that depth and Chl were the basic factors affecting the wet biomass of the main plankton groups. Wet biomass of …

Sex On The Reef: Observations Of Coral Spawning In Dry Tortugas National Park, Karen L. Neely, Tracy A. Ziegler
Marine & Environmental Sciences Faculty Articles
In Florida’s remote Dry Tortugas National Park, coral reefs are an important management priority. Reproduction of coral species is difficult to monitor, however, and the reproductive potential of coral colonies at the park has been a matter of concern for several years. Two threatened species, elkhorn coral (Acropora palmata) and pillar coral (Dendrogyra cylindrus), were targeted for observation during their predicted annual spawning event in August 2014. Over a three-night period, both species were observed releasing gametes in near synchrony with observations at other sites in the Florida Keys. That these organisms are capable of being …

Marine & Environmental Sciences Faculty Articles
Population models are important for resource management and can inform about potential trajectories useful for planning purposes, even with incomplete monitoring data. From size frequency data on Luhuitou fringing reef, Hainan, South China Sea, a matrix population model of massive corals (Porites lutea) was developed and trajectories over 100 years under no disturbance and random disturbances were projected. The model reflects a largely open population of Porites lutea, with low local recruitment and preponderance of imported recruitment. Under no further disturbance, the population of Porites lutea will grow and its size structure will change from predominance of …

How The Bending Kinematics Of Swimming Lampreys Build Negative Pressure Fields For Suction Thrust, Brad J. Gemmell, Stephanie M. Fogerson, John H. Costello, Jennifer R. Morgan, John O. Dabiri, Sean P. Colin

Swimming animals commonly bend their bodies to generate thrust. For undulating animals such as eels and lampreys, their bodies bend in the form of waves that travel from head to tail. These kinematics accelerate the flow of adjacent fluids, which alters the pressure field in a manner that generates thrust. We used a comparative approach to evaluate the cause-and-effect relationships in this process by quantifying the hydrodynamic effects of body kinematics at the body-fluid interface of the lamprey, Petromyzon marinus, during steady-state swimming. We compared the kinematics and hydrodynamics of healthy control lampreys to lampreys whose spinal cord had been …
