Plant-Pollinator Interactions in a Changing World: Cryptic Specialization, Pollinator Movement, and Landscape Genetics of Pollinator-Dependent Plants

Creator:: Gannon, Dustin G.
Abstract:: Plant-pollinator mutualisms are one of the most prevalent and economically important mutualisms in nature. Like many other ecological systems, plant-pollinator communities are threatened by anthropogenic activity, both directly (e.g., habitat conversion and fragmentation) and indirectly (e.g., climate change). While we are aware of many of the activities that adversely impact...

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...

Effects of Predator Introductions on Population and Community Dynamics

Creator:: Ingeman, Kurt E.
Abstract:: There is increasing awareness that human activities are altering the ways that natural systems operate and that local shifts in species composition and abundance can lead to abrupt and irreversible global change. Therefore, understanding the processes that buffer biological communities from critical shifts and how our actions affect natural stabilizing...

The Mathematics of Critical Shifts in Ecological Networks with Alternative Stable State Theory, A Potential Framework for Early Warning Indicators

Creator:: Kupperman, Michael D.
Abstract:: A long running problem in mathematical biology is the prediction of extinction events, a specialized case of the larger global stability problem found in differential equations and dynamical systems theory. A central technical question is how to introduce the randomness observed in real ecological systems not accounted for in deterministic...

Understanding chlamydial biology through genome sequencing and comparative genomics

Creator:: Jeffrey, Brendan
Abstract:: The human pathogen Chlamydia trachomatis displays different phenotypes between serovars both in vivo and in vitro. The study of chlamydial biology has been hampered by the lack of a tractable genetic system. Here, chlamydial isolates with known phenotypes as well as strains generated though recombination were fully sequenced to address...

Branching random walk and probability problems from physics and biology

Creator:: Johnson, Torrey
Abstract:: This thesis studies connections between disorder type in tree polymers and the branching random walk and presents an application to swarm site-selection. Chapter two extends results on tree polymers in the infinite volume limit to critical strong disorder. Almost sure (a.s.) convergence in the infinite volume limit is obtained for...

Student, teaching assistant, and faculty learning during innovation in an introductory biology course

Creator:: Blair, Lesley
Abstract:: This study examined the dynamics of student, teaching assistant (TA), and faculty learning in relationship to implementation of a genetic technologies project in a university introductory biology course. Research focused on the types of learning that occurred and the various factors impacting that learning. Study participants included 25 undergraduate non-science...

Dixy Lee Ray, marine biology, and the public understanding of science in the United States (1930-1970)

Creator:: Ellis, Erik
Abstract:: This dissertation focuses on the life of Dixy Lee Ray as it examines important developments in marine biology and biological oceanography during the mid twentieth century. In addition, Ray's key involvement in the public understanding of science movement of the 1950s and 1960s provides a larger social and cultural context...

Characterization of Neurospora crassa and Fusarium graminearum mutants defective in repeat-induced point mutation

Creator:: Pomraning, Kyle R.
Abstract:: Mutation of repetitive DNA by repeat-induced point mutation (RIP) is a process that occurs in many filamentous fungi of the Ascomycota during the sexual cycle. Concurrently, direct DNA repeats are often deleted by homologous recombination at high frequency during the sexual cycle. Thus, the processes of RIP and deletion compete...

Initiation of coral/algal symbioses : the role of cell surface lectin/glycan interactions in recognition and specificity

Creator:: Wood-Charlson, Elisha M.
Abstract:: Mutualistic associations between cnidarians, such as corals, and photosynthetic dinoflagellate algae provide the trophic and structural foundation of coral reef ecosystems. In many cases, this intracellular mutualism is highly specific and must be established anew for each generation of host corals. The ability to maintain partner specificity across generations implies...
