In an effort to reduce dependence on petroleum, promote economic growth and diversification, and reduce human-induced climate change, the United States has developed a strategy that includes bio-based production of energy and compounds that can be used as precursors for industrial processes. It has been suggested that microorganisms with differing physiological capacities may provide an opportunity to generate commercially valuable products in a more sustainable, commercially viable manner.

This project addresses the needs for IPM programming to serve the Massachusetts urban population. Through partnerships and collaborations, educational and service programs will be provided that encompass the structural pest control industry, bed bugs, Lyme disease, and IPM in K-12 schools, institutions of higher learning and the health care industry.

Family forest owners (FFOs) control 263 million acres (or 35%) of U.S. forests. In the eastern U.S, FFOs control more than 50% of the forests (Butler, 2008). The average age of FFOs is over 60 years old. It is estimated that over 75% of family forest land is owned by people over the age of 55 and nearly 50% is owned by people over the age of 65 (Butler, et al. 2016). In the coming years, nearly 3.8 million FFOs will be deciding the future of their land. We are, in fact, in the midst of the largest intergenerational shift of land our country has ever experienced.

There is concern over the presence of pollutants in our water supply. Among the pollutants that have elicited the greatest alarm are those that can alter the development and reproduction of aquatic organisms and potentially harm human health. These chemicals, generally referred to as endocrine disrupting compounds (EDCs), enter waterways as runoff from farms, effluent from wastewater treatment and manufacturing plants, and leachate from septic systems.

This project will develop and diversify Crambe (an oilseed crop) and brassica (mustard green) species as dedicated bioenergy crops for biodiesel production. The proposed strategy will increase crop biomass and seed yields while growing these crops on marginal and heavy-metal-contaminated lands, thus increasing both yield and arable acreage. This approach to cultivation on contaminated sites and marginal lands will not create competition for land or displacement of food crops.

Fishing is highly popular worldwide and a dominant use of many fish stocks (Cooke & Cowx 2004). While recreational fisheries were traditionally harvest-dominated, catch and-release has become a major practice in many developed countries, and is growing in popularity in developing countries due to a combination of increasing harvest regulations and shifting angler priorities. (Cowx 2002; FAO 2012; Freire et al. 2012; Brownscombe et al. 2014a).

Predation is considered a key limiting process, and management actions for declining species, such as forest-dwelling songbirds, are often aimed at reducing impacts of predation. This is of particular concern in areas undergoing urbanization, since densities of potential predators tend to increase dramatically with urbanization.

This grant is a "proof-of-principle" proposal to determine if imidacloprid, a neonicotinoid insecticide, causes obesity and insulin resistance (IR) in the insect obesity and IR model, D. melanogaster, in a manner similar, if not identical, to the effects seen with this compound when administered to mice.

Eastern white pine (Pinus strobus) is a crucial ecological and economic component of forests in the eastern U.S. and Canada. In the southeastern U.S., white pine is an especially critical associate of forests in the Appalachian Mountains as hemlock trees have been in decline due to the exotic hemlock woolly adelgid (Adelges tsugae).

This project aims to design and conduct economic laboratory experiments to investigate behavioral issues related to the defense of common pool resources from encroachment by outsiders. Common pool resources are assets -- often natural assets such as forests, fisheries and water supplies --t hat are managed by a group of users. These resources are prone to inefficient use because individuals tend toward over-exploitation relative to what would maximize the welfare of the group.
