Structure and Dynamics of the Canine (Canis familiaris) Nasal Microbiome

Creator:: Knorr, Elizabeth
Abstract:: The diverse community of bacteria living within and on host organisms, known as the microbiome, has an important role in maintaining host health. Dysbiosis, known as a change in the healthy community of the microbiome, has been associated with a number of diseases across host organisms and body sites including...

So Long and Thanks for All the Sponge: Cryptic Intertidal Communities, Consequences of Ocean Acidification, and New Directions for Science Education

Creator:: Rickborn, Alissa J.
Abstract:: The current generation of scientists will be asked to mitigate climate change, stall biodiversity loss, and protect ecological communities. These are tasks that require a knowledge of both ecological and social systems to be undertaken successfully. Therefore, my dissertation spans the fields of community ecology and social sciences in an...

Stage-structured interactions and their consequences across levels of biological organization

Creator:: Segui, Leah Mupas
Abstract:: A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...

Investigating variation in immunity and infection risk in wild ungulates

Creator:: Dugovich, Brian S.
Abstract:: In the midst of the sixth mass extinction, understanding wildlife disease spillover is critical to maintaining protected wildlife areas. Studying ecoimmunology and wildlife disease ecology helps to understand immune and disease traits in an ecological context, which is invaluable in preventing pathogen spillover between livestock and wildlife. To investigate this...

Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

Creator:: Tanis, Brian P.
Abstract:: The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

Thermal Tolerance and Adaptation in Cnidarians: An Investigation of Host Transcriptomic Responses and Heritable Variation Across Natural Populations

Creator:: Dziedzic, Katherine E.
Abstract:: Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...

Marine Mass Mortality in a Global Change Context: Impacts on Individuals, Populations and Communities

Creator:: Sullivan Stack, Jenna
Abstract:: Human actions are pushing natural systems into states that have no historical precedent. In response, empirical and theoretical researchers are increasingly focused on developing ways to predict the responses of ecological systems to change. However, significant knowledge gaps remain, often leading to “ecological surprises” where observed impacts of global change...

Habitat Use and Ecological Interactions of Invasive Lionfish in the Bahamas

Creator:: Davis, Alexandra C. D.
Abstract:: Invasive species are a growing global economic and ecological problem. Invasive Indo-Pacific lionfish (Pterois spp.) are known to have extreme negative effects on coral-reef communities in the Bahamas, so understating their distribution within and among reefs, what limits their local movements, and the effects they have on native prey species...

Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

Creator:: Coblentz, Kyle E.
Abstract:: Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

Stress Physiology in Free-ranging Female African Buffalo (Syncerus caffer) : Environmental Drivers, and Immunological and Infection Consequences

Creator:: Spaan, Johannie M.
Abstract:: Fecal glucocorticoid metabolites (FGMs) are commonly used as indicators of an animal’s stress response in behavioral and eco-physiological studies. Stress in wild animals represents an immediate measure of the physiological response to changes in the environment, and, potentially, a prospective assessment of the animal’s health and well-being. In wild mammals,...
