Habitat Utilization Of Marsh And Adjacent Submerged Landscape By Fish And Macroinvertebrates In A Gulf Of Mexico Tidal Oligohaline Environment, Tia Offner 2023 Mississippi State University

Habitat Utilization Of Marsh And Adjacent Submerged Landscape By Fish And Macroinvertebrates In A Gulf Of Mexico Tidal Oligohaline Environment, Tia Offner

Theses and Dissertations

Estuarine habitats are considered nursery habitats for fishes and invertebrates, but oligohaline environments are critically understudied. Using a seine net and fyke nets, we sampled Back Bay, Mississippi (USA), a low salinity estuary, once a month for a year to explore the temporal use of the marsh and adjacent submerged landscape by nekton species. We also looked at whether there is evidence of habitat preference in the most numerous nekton species. We used a novel habitat usage index (HUI) to compare seine and fyke net catches of our top 10 species, and evaluated catch size in relation to maturation size. …

Biophysical Factors Affecting Habitat Suitability For Crassostrea Virginica, Jason D. Tilley 2023 Gulf Coast Research Laboratory

Biophysical Factors Affecting Habitat Suitability For Crassostrea Virginica, Jason D. Tilley

Dissertations

Oyster reefs provide a variety of important ecosystem services. However, the mortality rate of eastern oyster, Crassostrea virginica, the dominant species that produces oyster reefs in the northern Gulf of Mexico, is increasing at an alarming rate due to a variety of abiotic and biological factors. I examined how biophysical factors, including the less-studied fatty acid profiles of the suspended particulate matter on which oysters feed, influenced morphometric condition of C. virginica.

I sampled suspended particulate matter (SPM) and oysters in-situ in the western Mississippi Sound, which historically supported the majority of oyster production in Mississippi waters. Sampling …


Spawning Asynchrony Of The Endangered Acropora Cervicornis: Are Light Pollution And Abnormally Warm Temperatures The Culprits?, Krista Laforest 2023 Nova Southeastern University

Spawning Asynchrony Of The Endangered Acropora Cervicornis: Are Light Pollution And Abnormally Warm Temperatures The Culprits?, Krista Laforest

All HCAS Student Capstones, Theses, and Dissertations

The persistence of reefs relies on mature corals spawning synchronously to maximize fertilization and produce larvae to replenish local populations. Corals synchronize the release of gametes by responding to temperature, sun, and moon light cycles; however, abnormalities in these patterns can disrupt synchrony. This study is the first to describe regional asynchronous spawning of Acropora cervicornis by quantifying gamete development and spawning times among two reefs, an in situ nursery off Fort Lauderdale, and an in situ nursery in the Florida Keys. While A. cervicornis in the Florida Keys synchronously spawned within the predicted window of 2-5 days after the …


Evaluating Habitat Use By Nekton In Widgeon Grass (Ruppia Maritima), Shoal Grass (Halodule Wrightii), And Unvegetated Bottom Habitats In The Grand Bay National Estuarine Research Reserve, Jessica Woodall 2023 The University of Southern Mississippi

Evaluating Habitat Use By Nekton In Widgeon Grass (Ruppia Maritima), Shoal Grass (Halodule Wrightii), And Unvegetated Bottom Habitats In The Grand Bay National Estuarine Research Reserve, Jessica Woodall

Master's Theses

Seagrass beds support high biodiversity and animal abundance, serve as feeding grounds for a variety of animals, offer shelter from predation, and act as a nursery habitat for juveniles. The species composition of seagrass beds can impact their use as habitat by animals. Two common species of seagrass in the Gulf of Mexico are Ruppia maritima (widgeon grass) and Halodule wrightii (shoal grass). The shallow coastal waters of the Grand Bay National Estuarine Research Reserve (NERR) support both species, but the use of each seagrass as habitat by nekton is poorly understood, which can limit management decision-making. Nekton communities were …

Fishing And Fear Effects Interact To Shape Herbivory On Coral Reefs, Bethany M. Tilton 2023 Nova Southeastern University

Fishing And Fear Effects Interact To Shape Herbivory On Coral Reefs, Bethany M. Tilton

All HCAS Student Capstones, Theses, and Dissertations

Predation influences animal behavior and shapes ecological structure and function through lethal effects and fear effects. On coral reefs, fear effects can alter the distribution and intensity of herbivory by herbivorous reef fishes. This includes the browsing functional group, which potentially reverses macroalgal phase shifts and promotes reef recovery. Herbivory by multiple functional groups may increase on coral reefs through the use of NTZs (no-take zones) but few studies have examined the extent to which small-scale NTZs (< 0.5 km2) influence fear effects and perceived predator presence on reefs. This study aimed to determine whether fear effects on browsers on …


A Rapid Site Selection Assessment As An Indicator Of Stony Coral Microfragment Outplant Success, John J. Alfirevich 2023 Nova Southeastern University

A Rapid Site Selection Assessment As An Indicator Of Stony Coral Microfragment Outplant Success, John J. Alfirevich

All HCAS Student Capstones, Theses, and Dissertations

Microfragmentation of massive stony coral species is a technique being utilized to propagate corals asexually to help restore coral reefs. Microfragmentation consists of cutting corals into 3 cm diameter or less fragments, which boosts growth rates. However, in some locations the size of microfragments make them vulnerable to parrotfish predation and benthic overgrowth, reducing survival. As such, a method to identify key site characteristics which promotes microfragment outplant success, particularly one that can be performed quickly across multiple areas is needed. A rapid site assessment conducted prior to microfragment outplanting was performed at 12 randomly selected sites within the Kristin …

Psammocora Stellata Distribution At Devil's Crown, Floreana Island, Galápagos Islands, Ecuador, María José Guarderas Sevilla 2023 Nova Southeastern University

Psammocora Stellata Distribution At Devil's Crown, Floreana Island, Galápagos Islands, Ecuador, María José Guarderas Sevilla

All HCAS Student Capstones, Theses, and Dissertations

In the Galápagos Archipelago, the free-living nodular coral Psammocora stellata is a common species that does not form reef structures. However, it is a key component of the ecosystem by increasing habitat complexity and, consequently, species diversity. This species experienced a drastic decline in Devil’s Crown channel, Floreana Island, where it disappeared after the 1982-83 El Niño-Southern Oscillation, presumably by displacement of unattached colonies by strong surface waves and currents. This assemblage has now recovered to pre-impact levels. A combination of underwater photoquadrats from 2007 and 2009 and recent (2023) orthomosaics were used to determine changes in coral densities and …

The Sociocultural Significance Of Maine's Oyster Based On Media Coverage Analysis, Syeira Clark 2023 University of Maine - Main

The Sociocultural Significance Of Maine's Oyster Based On Media Coverage Analysis, Syeira Clark

Honors College

Throughout the last decade, the oyster aquaculture industry in Maine has boomed, with 6 million pounds of oysters being harvested in 2021, about the amount that was harvested in 2016 (Cough, 2022). According to the founders of the Maine Oyster Trail, there are over 150 oyster farms currently operating on Maine’s coast, which is about twice as many as there were in 2016 (Maine Sea Grant). With this boom in the industry has come a wave of opportunity, as well as news coverage about the shellfish. This study examines the socio-cultural significance to the state of Maine. While the oyster …


Interactions Between Sediment Mechanical Structure And Infaunal Community Structure Following Physical Disturbance, William Cyrus Roger Clemo 2023 University of South Alabama

Interactions Between Sediment Mechanical Structure And Infaunal Community Structure Following Physical Disturbance, William Cyrus Roger Clemo

Theses and Dissertations

Shallow, river-influenced coastal sediments are important for global carbon storage and nutrient cycling and provide a habitat for diverse communities of invertebrates (infauna). Elevated bed shear stress from extreme storms can resuspend, transport, and deposit sediments, disrupting the cohesive structure of muds, and sorting and depositing sand eroded from beaches. These physical disruptions can also resuspend or smother infauna, decreasing abundances and changing community structure. Infaunal activities such as burrowing, tube construction, and feeding can impact sediment structure and stability. However, little is known about how physical disturbance impacts short and long-term sediment habitat suitability and whether disturbance-tolerant infauna influence …

Research outputs 2022 to 2026

Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil depth, site name, dry bulk density, SOC, and/or soil organic matter (SOM). The MarSOC dataset includes 17,454 data points from 2,329 unique locations, and 29 countries. We generated a general transfer function for the conversion of SOM to SOC. Using this …
