Living Shoreline Stabilization To Increase Resiliency At De Soto National Memorial, Linda Walters, Melinda Donnelly, Christian Pilato, Suzanne Connor
Living Shoreline Stabilization To Increase Resiliency At De Soto National Memorial, Linda Walters, Melinda Donnelly, Christian Pilato, Suzanne Connor
CEELAB Research Data
De Soto National Memorial (Bradenton, FL) is an important location where both Native Americans and De Soto's army of soldiers once lived. We have been working closely with the National Park Service and the University of Central Florida to understand how to best stabilize this shoreline using living shoreline techniques combined with long-term natural recruitment. Stabilizing De Soto's shoreline is essential to decrease erosion and shoreline loss to protect the Park's cultural and natural resources, especially the numerous historically significant shell middens. Through pre-restoration monitoring, we determined that high-energy boat wakes were limiting natural mangrove recruitment. Lack of retention of …
Shoreline Characterization In The Northern Indian River Lagoon, Melinda Donnelly, Michelle Shaffer, Suzanne Connor, Linda Walters
Shoreline Characterization In The Northern Indian River Lagoon, Melinda Donnelly, Michelle Shaffer, Suzanne Connor, Linda Walters
CEELAB Research Data
The purpose of this project was to evaluate current conditions of estuarine shorelines in the northern section of the Indian River Lagoon system, including Mosquito Lagoon, north Indian River, and Banana River. From January 2016 through June 2018, we evaluated structural and functional characteristics of 374 miles of shoreline, from Ponce Inlet in Volusia County to Sebastian Inlet in Brevard County (11,000+ data points). Hard-armoring accounted for approximately 50% of total shoreline, evenly divided between shoreline with bulkheads (25%) and hardened slopes (25%). Forty-five percent of shoreline without hard-armoring had anthropogenic alterations (i.e. mosquito impoundments, railroads and roadways, residential and …

A Cohort-Based Program To Help Students Prepare A Conference Research Presentation, Alanna Lecher
Florida Statewide Symposium: Best Practices in Undergraduate Research
Students move through many first time experiences when navigating their undergraduate and graduate education. Such experiences include the first time students submit an article to a peer-reviewed scientific journal, attend a conference, and conduct fieldwork. The cohort model has been shown to be effective in increasing success in undergraduate education, and it can be adapted to helping students succeed in these novel experiences as well. This presentation will explore one program where the cohort model was implemented to aid undergraduate students preparing their first conference presentation on a scientific research project. Program structure and implementation will be described.
Preventing Introductions To Sustain Healthy Ecosystems: Establish Eradication Protocols For A Popular Aquarium Seaweed, Julie Deslauriers
Preventing Introductions To Sustain Healthy Ecosystems: Establish Eradication Protocols For A Popular Aquarium Seaweed, Julie Deslauriers
The Pegasus Review: UCF Undergraduate Research Journal
Aquarium release, a vector that introduces non-native species, recently caused the costly invasion of the green macroalga (seaweed) Caulerpa taxifolia along the Californian, Mediterranean, and Australian coasts. C. taxifolia was classified by the International Union for the Conservation of Nature as one of the world's 100 worst invasive species and cost California over $7 million to control with black tarps and chlorine bleach. Since the incident, educational efforts at conferences and conventions have influenced more than 50% of surveyed hobbyists to switch to another green macroalga, Chaetomorpha, as their primary alga in their saltwater tanks. C. taxifolia and Chaetomorpha …
The Impact Of Crown Conch On Intertidal Oyster Populations In Mosquito Lagoon, Casey Craig, Courtney Buck, Chelsea Landau, Jordan Filipponi
The Impact Of Crown Conch On Intertidal Oyster Populations In Mosquito Lagoon, Casey Craig, Courtney Buck, Chelsea Landau, Jordan Filipponi
The Pegasus Review: UCF Undergraduate Research Journal
Commercial oyster harvesters in Florida have long complained that the Florida crown conch Melongena coronais in competition with them for harvestable-sized eastern oysters (Crassostrea virginica). Harvesters also suggest that crown conch, rather than overharvesting, has led to a large decline in oyster populations. To determine the role of M. corona on oysters in Mosquito Lagoon, we must first better understand the biology and ecology of M. corona., and to comprehend crown conch biology in Mosquito Lagoon along the east coast of central Florida, we conducted a three-part experiment in Canaveral National Seashore (northern Mosquito Lagoon). Specifically, …
Determining Tidal Elevations In Dry Elements Within A Coastal Salt Marsh Model, Martin Coleman
Determining Tidal Elevations In Dry Elements Within A Coastal Salt Marsh Model, Martin Coleman
The Pegasus Review: UCF Undergraduate Research Journal
An integrated hydrodynamic/marsh biomass model is a useful tool for analyzing multiple hydrologic activities on a shoreline. A key component of this type of model is the location of local tidal elevations. During astronomic tide simulations, nodes in the finite element mesh are either wet or dry. At nodes that are continuously wet during the simulation, tidal elevations are computed from ADCIRC-2DDI (ADvanced CIRCulation) output. In areas that are intermittently wetted, tidal constituents cannot be determined using ADCIRC because the drying of nodes leaves a gap in the water-level time series. The Inverse Distance Weighting (IDW) interpolation method can be …
Improving Community-Based Shoreline Erosion Stabilization Projects: Impacts Of Potential Nurse Plants On Red Mangrove Biomass Production And Survival, Paula Yespelkis, Melinda Donnelly
Improving Community-Based Shoreline Erosion Stabilization Projects: Impacts Of Potential Nurse Plants On Red Mangrove Biomass Production And Survival, Paula Yespelkis, Melinda Donnelly
The Pegasus Review: UCF Undergraduate Research Journal
Mangrove communities provide habitat for many terrestrial and aquatic species and act as nurseries and breeding grounds for fish, crustaceans, and birds. They also protect coastal areas from erosion and storm events. However, globally 35% of mangrove habitat has been degraded or destroyed, making mangroves one of the most endangered ecosystems on earth. Thus, there is a demand for methods to restore mangrove habitats successfully. The red mangrove (Rhizophora mangle) is often associated with other marsh plants. We investigated whether two marsh plants (Batis maritima, Sarcocornia perennis ) act as nurse plants and increase R. mangle success by altering seedling …
Cold Temperature Effects On Byssal Thread Production By The Native Mussel Geukensia Demissa Versus The Non-Native Mussel Mytella Charruana, Sasha Brodsky
The Pegasus Review: UCF Undergraduate Research Journal
Mytella charruana is a Central/South American mussel that has been found as an introduced species along the southeastern Atlantic coast of the United States since 2004. Previous experiments have determined the lethal thermal minimum of M. charruana to be between 6-9° C. Continuous byssal thread production is essential for mussel survival as it is used for attachment to substrates in natural environments, but may decrease when environmental conditions deviate from their optimum. We sought to determine whether M. charruana exhibits a non-lethal, thermal response involving a reduction in byssal thread production. Mytella charruana and, for comparison, a native mussel species, …
Allelopathy Of Invasive Brazilian Pepper (Schinus Terebinthifolius) On Mobile Invertebrates From The Indian River Lagoon, Lori Konar, Tiffany Sheldon, Stephanie Garvis, Melinda Donnelly
Allelopathy Of Invasive Brazilian Pepper (Schinus Terebinthifolius) On Mobile Invertebrates From The Indian River Lagoon, Lori Konar, Tiffany Sheldon, Stephanie Garvis, Melinda Donnelly
The Pegasus Review: UCF Undergraduate Research Journal
Brazilian pepper Schinus terebinthifolius is a highly invasive plant species that can be found in many different ecosystems, including the edges of estuaries in south and central Florida. Brazilian pepper fruits contain chemicals that are toxic to native salt marsh plants. Previous researchers found that high densities of crushed Brazilian pepper fruits negatively impacted growth and final biomass of the black mangrove Avicennia germinans and the red mangrove Rhizophora mangle. Here, we investigated the impact of S. terebinthifoliuson the viability of mobile estuarine invertebrates commonly found in the Indian River Lagoon, as well as the brine shrimp, a …

Shoreline Characterization For Northern Indian River Lagoon And Mosquito Lagoon, Melinda J. Donnelly, Linda Walters, Michelle Shaffer
CEELAB Research Data
The purpose of this project was to evaluate the current conditions of estuarine shorelines in Mosquito Lagoon and northern Indian River. The shoreline assessment is the first phase in the development of a shoreline restoration suitability model for the northernmost section of the Indian River Lagoon system, in order to better conserve and restore shorelines and promote sustainable use of natural resources. The shoreline survey methodology was developed by St. Johns River Water Management for northeastern Florida and was adapted for applications in Brevard and Volusia Counties. Between November 2017 through June 2018, shoreline evaluations were completed at transects located …
Oyster Reef Restoration: Impacts On Infaunal Communities In A Shallow Water Estuary, Katherine P. Harris
Oyster Reef Restoration: Impacts On Infaunal Communities In A Shallow Water Estuary, Katherine P. Harris
Honors Undergraduate Theses
Oyster reefs are important estuarine ecosystems that provide habitat to many species including threatened and endangered wading birds and commercially important fishes and crabs. Infaunal organisms (i.e. small, aquatic animals that burrow in the sediment) are also supported by oyster reef habitats. Infaunal organisms are critical to marine food webs and are consumed by many important species that inhabit coastal estuaries. However, over the past century 85% of shellfish reef habitats have been lost, making restoration of these areas vital. Due to their important role in coastal food webs, infauna is hypothesized to be a strong indicator of habitat productivity …
Impact Of Increased Green Turtle Nesting On Loggerhead Fitness, Amanda R. Carmichael
Impact Of Increased Green Turtle Nesting On Loggerhead Fitness, Amanda R. Carmichael
Honors Undergraduate Theses
Marine turtles exhibit strong fidelity to their nesting beaches, making the conservation of nesting beaches important for ensuring successful sea turtle populations. Conservation of these nesting beaches involves understanding how species interact with the environment and each other, and understanding how environmental change and population growth can affect the suitability of the nesting habitat. The Archie Carr National Wildlife Refuge (ACNWR) is unusual in its high density of sea turtle nesting by two species: green (Chelonia mydas) and loggerhead (Caretta caretta) turtles. The ACNWR in Melbourne Beach, Florida was established in 1991 due to the high density of loggerhead nesting, …
Infection Dynamics Of Herpesvirus In Gopher Tortoises, Joanne Saldanha
Infection Dynamics Of Herpesvirus In Gopher Tortoises, Joanne Saldanha
Honors Undergraduate Theses
Gopherus polyphemus, commonly known as the Gopher Tortoise, is a dryland reptile native to the southeastern United States. It is commonly a resident of longleaf pine and dry oak sand hill habitats. It is considered a keystone species because they dig deep burrows that provide shelter to them as well as many other animals. Habitat loss, fragmentation, and disease are major threats and have caused this species to be federally listed as a threatened species under the Endangered Species Act (ESA). Disease is a major threat to the gopher tortoise’s survival, and with declining populations, the need to investigate …
