Checklist And Key To The Millipede Species Of Georgia, United States, With Notes On Distribution, Lance Andrew, Bruce Snyder

Graduate Research Showcase

Millipedes are an exceptionally diverse class of animals that have an impact on soil structure and nutrient cycling. Despite their abundance, importance, and wide distribution, they are understudied compared to other animal taxa, and biogeographical information is scant. Georgia, though the largest state by land area east of the Mississippi River, has largely been overlooked by regional millipede checklists. Without baseline species distributions and abundances to inform wildlife management decisions, sufficient measures cannot be taken to preserve millipede biodiversity, especially in light of recent changes in climate and land use. Taxonomic resources for millipede identification in North America are also …

Assessing Endophyte Frequency Distributions And The Effect Of Epichloë Brachyelytri In The Chemotypic And Genotypic Diversity Of Brachyelytrum Erectum, Rachel Ann Sneed

Theses and Dissertations--Plant Pathology

Seed-transmissible epichloid fungal endophytes are best known for their roles as defensive mutualists in cool-season grasses. Historically, the discovery of fungal endophytes was driven by investigations of plant toxicity to livestock, followed by extensive study of their alkaloids and protection against insects and nematodes. Epichloae can produce four classes of alkaloids: ergot alkaloids, lolines (saturated aminopyrrolizidines), indole–diterpenes, and peramine. It is increasingly evident that these hereditary symbionts have much more diverse chemical profiles both in individual populations and between them. To this end, differences in chemotypic profiles of these symbionts may translate to different evolutionary and environmental advantages across plant …

An Innovative Restoration Mode “Macrophytes–Fishes–Benthons–Birds” Implemented In Aesthetic Plateau Wetlands, Junxing Yang, Xiaoai Wang, Xiaofu Pan, Yuanwe Zhang, Heqi Wu, Anli Wu

Bulletin of Chinese Academy of Sciences (Chinese Version)

Affected by both increasing human activities and climate change, Yunnan Plateau lakes were faced with threats such as water level decreasing, water-body reducing, and severe pollution. Many indigenous species were endangered or even disappeared. The ecological restorations implemented since 1980s almost all used alien species. As an inevitable result, severe negative impacts from alien species were observed on the Plateau wetland ecosystem and indigenous species. To solve these problems, with the support of relevant projects, an innovative restoration mode mainly with indigenous flag-species “macrophytes – fishes – benthons – birds” was proposed. This innovative mode was implemented respectively in Dianchi …

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 …

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

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 …

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, …
