Influence of River Plumes on Larval Fish Distributions, Predator-Prey Relationships, and Fitness in the Northern Gulf of Mexico

Creator:: Axler, Kelia E.
Abstract:: River plumes discharging into continental shelf waters have the potential to influence patchiness of larval fishes, prey, and gelatinous predators. Using a high-resolution plankton imaging system, we sampled larval fishes, copepods, and planktonic predators (ctenophores, hydromedusae, and siphonophores) across multiple freshwater pulses exiting the mouth of Mobile Bay (Alabama, USA)...

Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

Creator:: Hubert, David L.
Abstract:: At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

Investigating connections between the circadian system and aging in Drosophila melanogaster

Creator:: Long, Dani M.
Abstract:: Circadian clocks coordinate molecular, cellular, physiological, and behavioral processes with the 24-hour solar day. While clock functions are well understood in young animals, it is not clear how aging or neurodegenerative disease affects the various levels of the circadian system. A common symptom of many neurodegenerative diseases including Alzheimer’s disease...

The Long and Short of it: Dynamic Ways in Which Small Mammals Respond In-Situ to Environmental Gradients in Time and Space

Creator:: Grimes, Juniper E.
Abstract:: In the face of environmental stressors, change is imperative for species to remain in place. The nature and degree of this change is of great interest, as it sheds light into the ways in which species respond to ecological and habitat change and may continue to respond during periods of...

Communities in Flux: The Influence of Hydroperiod on Aquatic Invertebrate Communities in Temporary Ponds

Creator:: Kruse, Christi A.
Abstract:: A central theme of ecology is determining factors that influence species distributions. Within aquatic ecology, species present in flowing waters are primarily influenced by the natural flow patterns of the stream (natural flow regime paradigm) while explanations of species present in standing waters are further divided by habitat type. To...

Linking Space, Time, and Elevation through Diet: Stable Isotope Analysis of Functionally Diverse Rodents in the Great Basin

Creator:: Taylor, David S.
Abstract:: Ecology is focused on understanding how organisms interact with each other and their environments, across ecological, spatial, and temporal scales. Thus, understanding how processes and patterns of ecological systems change across space and time is a principle goal for conservation biologist globally. While many approaches exist for investigating the changing...

Context and Scale Mediate the Impact of Climate on a Widespread Avian Predator

Creator:: Brawner, Michael D.
Abstract:: Anthropogenic climate change is threatening biodiversity as I currently understand it. There is now a large body of work highlighting species responses, globally, to this threat. Importantly, responses at the species level emerge from responses at lower levels of biological organization (individuals and populations) across a species’ geographic range. For...

Adaptive Potential of Coastal Invertebrates to Environmental Stressors and Climate Change

Creator:: Burton, Andrea R.
Abstract:: Climate change presents multiple stressors that are impacting marine life. As carbon dioxide emissions continue to increase in the atmosphere, atmospheric and sea water temperatures increase. In addition, more carbon dioxide is absorbed into the oceans, reducing pH and aragonite saturation state, resulting in ocean acidification (OA). Tightly coupled with...

Scale and Pattern: Delineating the Effects of Local to Regional Processes and Species Identity in Producing Multi-scale Responses of Macroalgae

Creator:: Spiecker, Barbara J.
Abstract:: Understanding and predicting how regional to global scale processes affect macroalgal populations and communities requires elucidating the mechanisms underlying observed patterns. This dissertation identifies some of the underlying mechanisms that produce complex multi-scale responses of macroalgae across space and time by delineating the role of key local environmental drivers and...

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...
