It has been hypothesized that climate change will cause plant species ranges to shift northward with plants at the south end of ranges declining in vigor and growth rate. The purpose of this research is to test this hypothesis for red spruce and balsam fir along the southern end of the continuous distribution of these species, in Massachusetts. By measuring the growth patterns of these trees, we can determine if the southern end of the range has been declining, relative to more northern stands of these species.

With the rapid development and wide application of nanotechnology, the introduction of manufactured nanomaterials into both solid and liquid wastes (and to the environment) is inevitable through production, use, and disposal. It has been reported in 2008 that nano-TiO2 is leached out of house facades into receiving surface waters. Currently, there are over 800 products on the market containing nanomaterials such as lotions, sunscreens, paints, and socks. This research will determine the environmental behavior and process of several types of manufactured nanomaterials.
Increased use of biomass fuels is a promising option for renewable fuels that could decrease our dependence on oil and reduce greenhouse gases. Unfortunately, we currently do not have clear knowledge about the plant traits that should be considered bioenergy traits and should be subjected to breeding and selection. We propose to use a grass energy model organism (Brachypodium distachyon), and treatment with two promising plant biomass transformation techniques (biological and thermochemical conversion) to examine the effect of natural diversity on biofuel production efficiency.
Acid rain and atmospheric pollution continue to be regional and national problems. The site's data contributes to the accurate assessment of precipitation chemistry and the effectiveness of the nation's air pollution laws and regulations.
Global climate change and nitrogen deposition are processes that will only increase as industrialization continues. The purpose of this study is to understand the response of the microbially driven soil nitrogen cycle to the combined effects of temperature increase and nitrogen amendments in forest soils of New England. Terrestrial cycling of nutrients is of particular importance due to the effects nutrient cycling can have on plant growth and climate change.
Rural landscapes around the world face intense development pressures from nearby urban areas. In the United States, rampant, low-density development at the urban fringe consumed approximately 800,000 ha of land in the last decade (USDA Natural Resources Conservation Service 2004). New subdivision developments and new towns are blanketing the landscape, often with little or inadequate provision for green infrastructure. This is certainly the case in New England, one of the nation's most densely populated regions. For example, every day 16 ha.
With increased pressure to utilize more practical, ecological and economically feasible strategies in the management of turfgrasses, additional research is needed to identify best management practices aimed at preservation of water resources.

The goal of this research is to gain better insight into the decision making process of Massachusetts forest-owning families in regards to the future of their land so that educators may tailor outreach programs and material to help these families make informed decisions about it. The results will be shared with policy makers interested in supporting family decisions about the future of their land.
Reaching the potential for renewable biofuels depends on the development of new technologies that are able to release the energy stored in cellulose fibers. This research project centers around an unusual microbe, Clostridium phytofermentans, that can convert a broad range of biomass sources directly to ethanol without expensive thermochemical pretreatment. Further development of conversion processes using C. phytofermentans will create a path to renewable biofuels using our region's sustainable forestry and crop resources.
