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...
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...

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...
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...
Translocation experiments, in which researchers displace animals and then
monitor their movements to return home, are commonly used as tools to assess functional
connectivity of fragmented landscapes. Such experiments are purported to have important
advantages of being time efficient and of standardizing ‘‘motivation’’ to move across
individuals. Yet, we lack...

Computational simulations of disks are becoming an important tool to predict the the evolution of protostars and disks to better understand the formation of planets. Past research has shown that the evolution of disks and their protostar can be altered through the interaction between gravity and hydrodynamic instabilities. We perform...
Natural disturbances and human activities can alter the benthic composition of coral reefs and other marine ecosystems. Reef fishes that associate with particular structures on the sea floor, such as coral heads, may be vulnerable to perturbations of those habitats. The spread of a newly discovered crustose alga (Ramicrusta sp.)...
