1. Koontz, Austin C. Applied Species Delimitation in Microbial Taxa and Plants.

Degree: MS, Biology, 2020, Utah State University

Species are a fundamental concept in biology, and many subdisciplines in biology utilize species in aspects of theory and in the communication of results. Given the centrality of species in biological science, it can seem surprising that there is no universal definition amongst biologists of what, strictly speaking, a species is. In fact, there are, by some estimates, over 20 different "species concepts", and this lack of a consensus is termed "the species problem". This problem has theoretical underpinnings, but has become more relevant as advances in sequencing technologies over the past two decades have allowed researchers to probe the genetics of populations, and in doing so, uncover instances of genetically distinct populations within a species. This thesis explores issues in species delimitation in two broadly different scenarios. The first, in Chapter 2, involves grouping individuals in microbial communities, and using phylogenetics to inform the effects of different species boundary thresholds. The second, in Chapter 3, explores the genetic differences between varieties of a species complex of plant endemic to the Great Basin region of the western United States, including a variety endemic to Logan Canyon (Primula cusickiana variety maguirei, or Maguire's primrose). While the contexts of these chapters are largely different, they nevertheless share a distinguishing trait, common throughout much of biology: ambiguous species boundaries.

2. Tamjidi, Jelveh. The Consequences of Environmental Properties and Tree Spatial Neighborhood on Post-Fire Structure of Forest in Yosemite National Park.

Degree: MS, Wildland Resources, 2020, Utah State University

Separating the contribution of habitat filtering and dispersal mechanisms in forming species distribution remains a challenge in community ecology. Despite the effect of environmental variables in structuring communities, only restricted numbers of them were considered as a habitat dissimilarity. In Chapter 2, I used topography and soil properties to define habitats within the Yosemite Forest Dynamics Plot (YFDP). The soil enzymes were added in soil samples due to their important role in releasing nutrients into the soil environment. The preference of eleven species to a specific habitat were examined. Also, the relative importance of habitat filtering and dispersal limitation were examined. I found that more species associated with habitats defined by soil properties compare to those associated with topographically defined habitat. In addition, the contribution of dispersal process was greater in explaining change in species composition. In Chapter 3, I studied the underlying processes in shaping four abundant species spatial arrangement in YFDP. I examined the effect of habitat heterogeneity, dispersal process, fire event, interaction of adults on juveniles, and negative density dependence (as a result of increasing density) in shaping species spatial distribution. My results suggest that dominant species spatial patterns are partially explained by topographic variables, dispersal limitation, biotic interactions, and fire history.

3. Madsen, Marley. Patterns of Microbial Diversity and Community Composition in Slot Canyons, Rock Pools, and Other Ephemeral and Perennial Aquatic Habitats.

Degree: MS, Biology, 2020, Utah State University

Microbes are the most diverse life forms on the planet and perform many important ecological functions. However, despite the abundance, diversity, and ecological importance of microbes they are often overlooked and understudied in many natural systems, including freshwater habitats. This thesis details the first ever investigation of the microbial diversity and community composition within fresh water rock pools and slot canyons of the Colorado Plateau, Utah. The purpose of the study was to determine the relative importance of various microbial community assembly processes. This thesis also includes a meta-analysis of the microbial alpha diversity in other perennial and ephemeral aquatic systems around the globe. The purpose of the meta-analysis was to identify the relationship between microbial alpha diversity and disturbance from drying. Together, these studies complement one another by describing the microbial ecology of a very specific habitat type, rock pools, as well as a diverse group of globally distributed aquatic habitats. Advisors/Committee Members: Bonnie Waring, Paul Wolf, Will Pearse, ;.
