Analyzing The Shark Paleoecology Of Coastal Georgia From The Miocene And Pliocene Epochs, Joshua Lee Clark, Benjamin Angalet 2023 College of Coastal Georgia

Analyzing The Shark Paleoecology Of Coastal Georgia From The Miocene And Pliocene Epochs, Joshua Lee Clark, Benjamin Angalet

Georgia Journal of Science

The field of shark paleoecology often yields indecisive conclusions based on the limited fossilization of their anatomical structures, with the exception of their teeth. The majority of the Atlantic coast has been studied regarding the presence of certain prehistoric shark species from the Miocene, Pliocene, and Pleistocene epochs. However, information pertaining to the Georgia coast and understanding its potential community structure is relatively understudied. This study was conducted in which thousands of fossil shark specimens and subsequent marine fauna were collected from dredge spoils created by the US Army Corps of Engineers (USACE): Savannah District. A total of 5,127 fossil …

On Some Teratological Scorpions In The Natural History Museum, London And Checklist Of The Scorpiological Literature On Morphological Anomalies (Arachnida: Scorpiones), Danniella Sherwood, Luis F. De Armas

Euscorpius

Whilst undertaking curation in the collections of the Natural History Museum, London, the senior author came across a jar of scorpions marked ‘scorpions with curled feet’. Further investigation showed this jar was full of scorpions with teratological anatomy. We hereby document and illustrate all of the specimens and discuss their respective anomalies. Furthermore, a comprehensive checklist of the literature on anomalies in scorpions, including giving the life stage and sex where known, is compiled for the benefit of future workers.


Addressing Water Hyacinth (Pontederia Crassipes) Impacts On Aquatic Biota In Lake Okeechobee, Joseph Salerno 2023 Nova Southeastern University

Addressing Water Hyacinth (Pontederia Crassipes) Impacts On Aquatic Biota In Lake Okeechobee, Joseph Salerno

All HCAS Student Capstones, Theses, and Dissertations

The incursion of water hyacinth, Pontederia crassipes in Lake Okeechobee has resulted in management systems to be implemented to reduce the coverage of the invasive macrophyte. Its residence in the Lake Okeechobee ecosystem and the effects it has on organisms in the lake, whether it be positive or harmful is unknown. This study attempted to assess the potential effects that water hyacinth has on aquatic biota in Lake Okeechobee. Biotic data were collected on open water, water hyacinth covered, and native vegetation covered habitats via hook-and-line fishing, electrofishing, baited minnow traps, and the sampling of plant roots over a thirteen-month …

Hoberg, Kaylen Marie Soudachanh, Svetlana K. Bondarenko

MANTER: Journal of Parasite Biodiversity

In the biosphere, limits for diversity among species, communities, and biomes are revealed through intensive and extensive field-based inventory and assembly of voucher specimens and associated informatics examined in a phylogenetic, historical, ecological, and biogeographic arena. Archival resources for specimens and information contribute to a cumulative view of faunal structure and assembly under a comparative umbrella. Ultimately, species definitions, and inclusive partitions among populations and lineages, are fundamental in articulating hypotheses that examine interactions about evolution, the nature of organisms, and the condition of environments across space and time. We conclude our proposals establishing species limits for tapeworms of the …


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 …

Citizen And Community Science Approaches To Understanding Changes In Coastal Habitats Using Anecdata.Org, Alexis Garretson, Cait Bailey, Ashley Taylor, Alexis Dabulewicz, Beth Bisson, Nathan Dorn, K. Kaczor, Mary Ann Nahf, Hannah Webber, Mark Whiting, Jane Disney

Maine Policy Review

Coastal ecosystems are facing increasing threats from human activities and environmental changes. Climate change, in particular, presents challenges for policymaking as it is causing significant changes to the oceans and coastlines, with social, economic, and environmental impacts on coastal communities. However, there is often a lack of data at the appropriate scales to address these concerns. Online tools that support the collection of citizen science and community science data can provide stakeholders and policymakers with a wealth of information and data on ocean-related topics, such as water quality, marine biodiversity, and ocean health. Citizen science platforms, like Anecdata.org, can facilitate …


Novel Microbial Guilds Implicated In N2o Reduction, Guang He 2023 University of Tennessee, Knoxville

Novel Microbial Guilds Implicated In N2o Reduction, Guang He

Doctoral Dissertations

N2O is a long-recognized greenhouse gas (GHG) with potential in global warming and ozone depletion. Terrestrial ecosystems are a major source of N2O due to imbalanced N2O production and consumption. Soil pH is a chief modulating factor controlling net N2O emissions, and N2O consumption has been considered negligible under acidic conditions (pH <6). In this dissertation, we obtained solids-free cultures reducing N2O at pH 4.5. Furthermore, a co-culture (designated culture EV) comprising two interacting bacterial population was acquired via consecutive transfer in mineral salt medium. Integrated phenotypic, metagenomic and metabolomic analysis dictated that the Serratia population excreted certain …


Activity Patterns Of Whiptail Lizards (Aspidoscelis) Found In The Northern Chihuahuan Desert, Guillermo Alvarez 2023 University of Texas at El Paso

Activity Patterns Of Whiptail Lizards (Aspidoscelis) Found In The Northern Chihuahuan Desert, Guillermo Alvarez

Open Access Theses & Dissertations

Traditional lizard pitfall traps were modified to allow organisms to escape, while collecting valuable ecological data. Modified camera traps were capable of detecting the same species as traditional traps in a semi-arid environment, without posing the associated mortality risks. Pitfall-camera traps were used to sample the activity of the Side-blotched Lizard (Uta stansburiana) and the Southwestern Fence Lizard (Sceloporus cowlesi) in an urban wetland during four continuous years. Evaluations on activity pattern and the activity overlap between the two species revealed extensive overlap, with minor but significant seasonal shifts mediating coexistence. Traps were also effective at detecting other reptiles, invertebrates, …


Species Richness Of Moths In Parks Surrounded By Varying Levels Of ​Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett 2023 Belmont University

Species Richness Of Moths In Parks Surrounded By Varying Levels Of ​Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett

Science University Research Symposium (SURS)

Moths can act as indicators of environmental wellness due to their pollution sensitivity and the complexity of biodiversity required to support their life cycles. Urbanization can impact the occurrence of moths in protected green spaces. Higher moth species richness was hypothesized to occur in parks surrounded by more rural areas. Three metropolitan parks were chosen in the Nashville area: downtown, within a suburban neighborhood, and in a rural area. Tree canopy cover and degree of impervious surfaces were assessed for each park and surrounding area using iTreeCanopy. Moths were attracted to a white sheet using a mercury vapor bulb, UV …


Trees In Our City How A Tree And A Small Patch Of Dirt Inspired A Classroom, Zuleika Hines 2023 Beyond Basic Learning

Trees In Our City How A Tree And A Small Patch Of Dirt Inspired A Classroom, Zuleika Hines

Occasional Paper Series

As a new Director in a new school, I knew that I wanted the children to have a curiosity for nature. But to lead the children to a place of discovery, they would need the opportunity to observe, play, and engage in elements of nature that would support hands-on activities both in the classroom and outside. When the opportunity came for me to build my own early childhood program, I knew that I had a unique opportunity to incorporate elements of nature in the design of the classroom. But I wanted nature to be local and the trees of our …


Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy 2023 Kennesaw State University

Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy

Symposium of Student Scholars

Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km2 and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …


Culled Lionfish Sexual Maturity Over A Four-Year Timespan​, Christina Bland, Jurgen Hauer, Bilal Saleem, Noelle James 2023 Kennesaw State University

Culled Lionfish Sexual Maturity Over A Four-Year Timespan​, Christina Bland, Jurgen Hauer, Bilal Saleem, Noelle James

Symposium of Student Scholars

Lionfish are invasive in the Atlantic and the Caribbean. Like many other invasive species, they do not have any natural predators in these areas, so their population can grow unchecked. This can decrease the population of native fish species due to lionfish eating to excess. Because of their impact on native species, resource managers have incentivized lionfish hunting. Hunters were paid $6 USD for every pound of lionfish they brought in, so they possibly favored larger lionfish to increase their reward which would lead to an adaptive advantage for fish of smaller sizes. We hypothesized that the lionfish bounty program …
