Facilitating Responses to Extreme Weather Events

Climate change is expected to increase the frequency and extent of future flood events in New England. Such events pose a substantial threat to both human and natural systems. Not only do the direct effects of extreme flooding harm human and ecosystems, but human responses in the lead up to and the aftermath of these events (such as forest and debris removal, channel alteration and armoring, and gravel mining) also create substantial disturbances. The effect of these human responses may be to alleviate or to exacerbate ecological damage and consequently the impacts of future flood events.

Faded Green? A Post Occupancy Study of Green Homes

Sustainable design and construction techniques for the United States housing sector are the most economically-effective strategies for preserving natural resources, reducing greenhouse gas emissions, and creating future energy security. More than 90-percent of the housing built in the Northeast is constructed from wood harvested from forests in New England. In the United States, 55-percent of timber production goes into the production of buildings.

Flies Impacting Livestock, Poultry and Food Safety

House flies are the major vector of numerous food pathogens (e.g., Escherichia coli). It has been suggested that the fly crop is the major reservoir for the pathogen and also that this is where horizontal transmission of antibiotic resistance occurs. The salivary glands of most flies involved in vectoring pathogens are also involved in pathogen transmission and their nutrient and pathogen uptake while feeding. We know very little about those factors involved in the regulation of both crop filling and emptying.

Food Based Approach for Prevention of Childhood Obesity

Both adult-onset obesity and childhood obesity pose real health risks, with childhood obesity known to be associated with increased risk of chronic diseases. With current rising trends of overweight and obese children, there is great need to develop additional practical approaches to target the obesity epidemic. The objective of this proposed research is to develop a feasible and practical food-based approach to help reduce the incidence of childhood obesity and overweight children.

Food Security, Food Practices, and Health Risks Among Pregnant and Postpartum Cambodian Women Living in Massachusetts

"Since the 1980's, the cities of Lowell and Lynn, Massachusetts have become home to large numbers of former refugees from Cambodia. Lowell is home to the second largest population of Cambodians in the United States. More than half of all Cambodian Americans live below the poverty line and a significant number are at high risk for food insecurity and hunger. Food insecurity has been associated with depression, poor micronutrient intake, and obesity among women of reproductive age.

Forests as carbon sinks, exploring the viability of carbon sequestration

Carbon dioxide is a greenhouse gas that contributes to global warming or climate change. One way to reduce the effect of carbon dioxide acting as a greenhouse gas is to accumulate it in trees and forests. Trees naturally take in carbon dioxide as part of growth, and turn it into wood. Trees and forests act as a sink to collect and hold carbon and as a result are thought of as part of the answer to mitigate increasing greenhouse gases in the atmosphere and increased global warming. Roughly 55% of all forests in the United States are privately owned and 92% of these owners are families.

Functional Genomics to Investigate and Characterize Genetic Factors Governing DMI-Sensitivity in Sclerotinia Homeocarpa

This research involves utilizing genomics and molecular biology tools to understand the basis of DMI (demethylation inhibitor) fungicide resistance dollar spot, the most important disease of turf grasses for golf courses. For this, we will take advantage of cutting-edge research tools in genomics and molecular biology to shed light on how the dollar spot fungus is able to overcome fungicides at the molecular level.

Gene-Silencing-Based High-Throughput Identification of Genes Required for the Nitrogen-Fixing Symbiosis

Unique among crop species, legumes produce their own nitrogen nutrient through a symbiosis with nitrogen-fixing bacteria collectively known as rhizobia. This nitrogen-fixing symbiosis is a complex system, and currently we know too few of the molecular players involved. This project will optimize two methods to reduce the activity of a given gene, and use these methods to screen for legume genes required for the function of the nitrogen-fixing symbiosis.

General Deterrence, Audit Uncertainty and Environmental Regulation

The efficacy of many government regulations, especially environmental policies, depends largely on the voluntary compliance of subjects. Monitoring of subjects and enforcement of the law acts to induce compliance; however, it is often too costly to employ subjects. Monitoring of subjects and enforcement of the law acts to induce compliance; however, it is often too costly to employ the resources required to induce perfect compliance.
