Guano Among Bat Species From Two Regions Shows Influence Of Geography And Diet On Bacterial Community, Rahma Ahmed, Thomas Mcelroy, Shannon Whitney, Lydia Moore
Guano Among Bat Species From Two Regions Shows Influence Of Geography And Diet On Bacterial Community, Rahma Ahmed, Thomas Mcelroy, Shannon Whitney, Lydia Moore
Symposium of Student Scholars
Studies of bat guano have shown that the diversity and structure of associated microbial communities can be related to factors such as host phylogeny, life history and reproductive stage, geography, and diet. Many insectivorous bat species in the southeastern U.S. have generalist diets that may shift seasonally to take advantage of abundant prey species or maximize caloric intake. Seasonal shifts in prey availability or consumption should be reflected in a guano microbiome change. We also expected to detect distinct guano microbiomes within species. Within species, distinct microbial communities related to geography, and finally life history and reproductive stage. We compared …
Initial Assessment Of Potential Relationships Between Plant Communities And The Soil Microbiome In Closed Forest And Longleaf Pine Restoration Sites., Sean Davis, Ian Kennedy
Initial Assessment Of Potential Relationships Between Plant Communities And The Soil Microbiome In Closed Forest And Longleaf Pine Restoration Sites., Sean Davis, Ian Kennedy
Symposium of Student Scholars
Longleaf pine is an endangered ecosystem characterized by high levels of biodiversity.
Our study took place in the Sheffield Wildlife Management Area located in the Piedmont ecoregion of Georgia in Paulding County. Fifty plots of 10 x 30 m2 were setup on south or north facing slopes, some in covered forest, and some in an area actively being restored for the longleaf pine. All trees above 1.37 m were identified and had their diameter measured, and species diversity, relative density, dominance, and frequency were determined. Herbaceous plant cover percentages were recorded in select plots. Soil samples were also collected …
Yakety Sacs: Laryngeal Air Sac Usage In Great Apes, Chelsea Trenbeath
Yakety Sacs: Laryngeal Air Sac Usage In Great Apes, Chelsea Trenbeath
Master of Science in Integrative Biology Theses
Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to the hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating …
Profiling Bat Activity And Species Presence In Managed Longleaf Pine Landscapes, Margaret Hunt
Profiling Bat Activity And Species Presence In Managed Longleaf Pine Landscapes, Margaret Hunt
Master of Science in Integrative Biology Theses
Restoration of native flora or reintroduction of at-risk fauna includes management practices that while encouraging presence and proliferation of target species, may adversely affect non-focal species. An endemic ecosystem undergoing restoration within the southeastern U.S. is that of the longleaf pine (Pinus palustris). Bats inhabit key ecological niches in forest ecosystems, including the longleaf pine ecosystem, and can be indicators of ecosystem condition. This study investigated the effects of current forest management practices and landscape management history on bat species presence and activity levels within habitat undergoing longleaf pine restoration. We deployed bat detectors in two wildlife management …
Conservation Genetics And Mark-Recapture Monitoring Of The Rare Pigeon Mountain Salamander (Plethodon Petraeus) Within A Highly Restricted Range, Kate Donlon
Master of Science in Integrative Biology Theses
Globally, amphibian species are experiencing declines at an alarming rate largely due to habitat loss, disease and climate change. Species with limited ranges are at an elevated risk of a significant decline in population numbers and extinction because of the inability to avoid and recover from these impacts. Long-term management plans are critical for conservation of species with small ranges; however, the knowledge required to develop effective plans is absent from the literature for many species. One such species is the Pigeon Mountain Salamander. The distribution of the Pigeon Mountain Salamander, Plethodon petraeus, is restricted to roughly 17 kilometers …

Assessing Feeding Preferences And Spatial Patterns Of Lagodon Rhomboides Linnaeus, Alexandria V. Lamle
Master of Science in Integrative Biology Theses
Mesograzers have the ability to greatly mitigate the effects of eutrophication in seagrass systems. In this study we look at pinfish (Lagodon rhomboides Linnaeus) as a potential epiphytic grazer and assess feeding preferences during a transitional stage in the ontogenetic diet shift exhibited by these fish. Since pinfish are abundant in seagrass meadows in the northern Gulf of Mexico, their dietary preferences have the potential to greatly impact seagrasses in this system. Twenty-four hour feeding trials were conducted to determine pinfish preference between seagrass (Thalassia testudinum) and algal epiphytes. St. Joseph Bay, FL was also surveyed to …
