While there are many more species of reptiles in the tropics than in temperate
latitudes, relatively little is known about the natural history of tropical species of
snakes. Even basic information, such as reproductive ecology and behavior, is lacking. Patterns of reproduction in tropical species differ from patterns in temperate...
School counselors are challenged with creating a wide range of programs to
address three developmental domains: personal/social, career, and academic, with an
increasing requirement to provide accurate and sufficient data substantiating their
professional contributions to students’ academic achievement. At the same time, the
professional literature reports that during adolescence there...
Direct anthropogenic stressors have caused drastic declines in wildlife populations over the past two centuries. In the face of these threats, spillover of infectious disease from domestic animals and livestock into wildlife, and novel interactions between parasites and pathogens within wildlife communities, have further suppressed already vulnerable populations. As management...
The increasing complexity and connectedness of energy networks has opened pathways for new forms of collaboration with energy consumers. Despite the emergence of the smart grid an array of policy options like demand-side management (DSM), many families continue to disregard daily household energy consumption, particularly during peak-use times of day....
The health and environmental impacts associated with traditional methods of household cooking and heating have driven the development and dissemination of many types of improved cookstoves and fuels. However, adoption rates, household cooking practices, and even household ventilation can directly influence the magnitude of real-world impacts. Given the highly contextual...
With rising concentrations of CO₂ in the Earth's atmosphere causing
concern about climate change, many solutions are being presented to
decrease emissions. One of the proposed solutions is to sequester excess
CO₂ in geological formations such as basalt. The deep subsurface is known
to harbor much of the microbial biomass...
This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...
Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...
Approximately half of the 6.4 million pregnancies occurring each year in the
United States are unintended (Finer & Henshaw, 2006). Unintended pregnancies, defined
as pregnancies not wanted at the time conception occurs, regardless of contraceptive use
(Chandra, Martinez, Mosher, Abma, & Jones, 2005) can have serious repercussions on
women, children,...
A new technique is developed to recover elemental tellurium (Te) from cadmium telluride (CdTe) which is abundantly available in photovoltaic semiconductor waste. The method is based on microchannel fluid flow with the use of a supported liquid membrane (SLM) between the donor (feed) and acceptor (strip) channels. A predictive theoretical...
