Independent effects of habitat loss and fragmentation on pollination : tropical forest fragmentation alters hummingbird movements and pollination dynamics

Creator:: Hadley, Adam S.
Abstract:: A growing body of work reveals that animal-mediated pollination is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, and (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects of such processes is critical in designing effective management strategies to limit...

How sweet is the land? Modeling caloric landscapes for tropical hummingbirds

Creator:: Birkett, Christina Nozomi and Birkett, Nozomi Fukui
Abstract:: Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...

SpaceLab, an N-Body Particle-Particle Ballistic Collision Simulation Tool with Applications in Celestial Body Dynamics

Creator:: Guidos, Job
Abstract:: This thesis conveys the key technical features and scientific applications of a particle-particle ballistic simulation tool (SpaceLab) as well as a high level overview of experiments it was designed for and executed on. SpaceLab simulates spherical particle interactions under any combination of self-gravity, sliding friction, rolling friction, Van-Der-Waals (VDW) cohesion...

Can Pollination Networks Withstand Species Loss? An Examination of Plant–Hummingbird Interactions and Their Responses to Experimental Removal of a Flowering Plant Species

Creator:: Leimberger, Kara G.
Abstract:: Global environmental change is causing local extinctions of species. When species depend on one another, as in the mutualistic relationship between plants and pollinators, loss of one interaction partner may cause cascading effects within the community – such as additional extinctions and reduced pollination services. Network theory provides a way...

Off-Axis Gamma Ray Burst Contribution to the Diffuse Gamma Ray Background in the 100-600 keV Range

Creator:: Hodges, Isaac
Abstract:: Gamma ray bursts (GRBs) are short, intense pulses of gamma rays that emit radiation in a narrow beam. Unless the beam is oriented towards the observer, it is often difficult to resolve the bursts against the diffuse gamma ray background (DGRB). The DGRB is a measured source of gamma rays...

Blood Processing Technologies for Cryopreserved Transfusion Products and Extracorporeal Treatment Applications

Creator:: Lahmann, John M.
Abstract:: There is a significant need for technological advancement in blood processing. New technologies in rapid processing of frozen blood products could significantly improve management of the blood supply chain in the United States by enabling on-demand use of frozen blood products that can be stored for 10 years instead of...

Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

Creator:: Parsotan, Tyler M.
Abstract:: Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...

Improving the post-thaw processing of cryopreserved red blood cells using a combined approach of mathematical modeling and microfluidics

Creator:: Lusianti, Ratih E.
Abstract:: This study lays the groundwork on potential techniques that could be employed to improve the post-thaw wash processing of cryopreserved human red blood cells. Transfusion of red blood cells is one of the most commonly practiced procedures in clinical medicine. Millions of red blood cell units are transfused to patients...

Evidence for Strengthening Hadley Cells and a Westward Expansion of the Walker Circulation from Assimilation of Paleoclimate Proxy Data

Creator:: Horlick, Kaleb A.
Abstract:: A synthesis of over 2000 paleoclimate proxy records is performed via a data assimilation framework that expands upon previous efforts by implementing a suite of physically-based proxy system models, and which provides the first example of an observationally independent, multi-seasonal (DJFM, JJAS) paleoclimate reanalysis. This methodology is contrasted against previous...

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...
