While current theories describing the insect-plant interaction
have emphasized the biochemical aspects of the relationship,
morphological components can also play a significant role in
determining which plants or tissues are susceptible to insect attack.
Xylem sap on which spittlebugs feed may lack many of the plant
compounds responsible for host...
A numerical solution to Hodgkin and Huxley's partial differential
system for the propagated action potential is presented. In
addition a three dimensional demonstration of the absolute refractory
period is given. Lastly, theoretical evidence supporting
Rushton's hypothesis is presented.
A primary goal of population genetics is to identify the role of
microevolutionary forces in producing observed patterns of molecular and phenotypic
variation. I conducted four studies in the northern leopard frog, Rana pipiens, to
determine just how mutation, migration, genetic drift, and selection influenced,
genetic structure of mitochondrial DNA...
Epichloë typhina, a fungal endophyte of
cool season grasses, is heterothallic and an obligate
out-crosser. In areas of endemism, its spermatia are
moved between stromata of the two opposite mating
types through egg-laying activities of Botanophila flies.
In western Oregon, where the fungus was inadvertently
introduced into seed-production fields of...
The Mien are recent United States immigrants from Laos. They left
Southeast Asia at a time of great political upheaval. Because of their
close ties with United States governmental operations during the Southeast
Asian war, conditions for Mien in Laos made flight imperative as
Pathet Lao forces now control the...

As the effect of ocean acidification (OA) on marine calcifiers is better understood, a range of potential mitigative strategies have been proposed, many of which are plagued by concerns of scale and feasibility. One oft-cited option is to increase the biomass of photosynthetic organisms to remove CO₂ from the water...
Throughout history, there have been many examples of political figures who have influenced fashion: from Theodore Roosevelt to Jacqueline Kennedy to Michelle Obama. Companies have taken advantage of the influence that political figures have as fashion opinion leaders, even going so far as to purchase keywords such as "Michelle Obama"...
Environment, safety and health (ESH) research has a strong tradition of
conducting research in manufacturing to improve workplace ESH conditions and has
tied its management strategy and technical practices to many significant priorities:
illness and injury prevention, environmental sustainability, corporate social
responsibility, compliance with regulatory and insurance requirements, and dealing...
Currently, the only anthrax vaccine licensed for human use in the United States is the Anthrax-vaccine-absorbed (AVA or Biothrax®). AVA suffers from several drawbacks, including a complicated and lengthy dosing schedule that requires six initial injections administered over eighteen months, followed by annual boosters. Therefore, a new generation anthrax vaccine...
This study investigated three questions: how, what kind of, and why were cross-border partnerships with non-US educational institutions developed at two public four-year US universities; how, what kind of, and why will cross-border partnerships with non-US educational institutions develop and/or change at US universities if nationalistic geo-political trends reflective of...
