Our plan is to evaluate the role, causative mechanisms, and interaction effects of biotic stressors (i.e. parasitic mites, pests, andpathogens) and abiotic stressors ((i.e. exposure to pesticides, poor habitat and nutrition, management practices) on the survival,health and productivity of honey bee colonies as well as within pollinator communities. Additionally we plan to develop and recommend "best practices" for beekeepers, growers, land managers and homeowners to promote health of honey bees and pollinator communities.
The red-backed salamander P. cinereus is an important component of forest ecosystems and, because they are widely distributed, occur at high densities, and are sensitive to environmental change and habitat disturbance/alteration, they are an ideal indicator species for assessing forest ecosystem health. However, the behavioral ecology of P.
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.
While most economists tout the benefits of using incentive-based policies (like emission taxes, emissions markets, and individual transferable quotas), many conceptual details concerning implementation and management of these policies have not been addressed. Recent research suggests that commonly-held notions of efficient incentive-based policies need to be modified to account for the costs of enforcing these policies.
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.
To address climate change and other considerations, there has been a push to plant trees in cities (Boston and New York are 2 nearby examples). Simply planting trees without understanding whether and why they survive and grow to provide benefits is an effort of dubious long-term value. Since measurements of these trees has been taken from their date of planting (2014), a longterm (5-yr) project that would involve continued post-establishment measurement, would provide valuable empirical data relevant to actual growing conditions.
Urbanization has increased demand for water and impaired aquatic ecosystems, threatening water resources worldwide. Climate change and more frequent droughts are expected to exacerbate this situation. Residential landscaping, especially lawns, are a major factor in increasing domestic water use.
Outreach efforts have been made to promote outdoor residential water conservation and promote methods that provide ecosystem benefits. These include water harvesting using rain barrels, infiltrating storm water using rain gardens, and landscaping with native plants.
The purpose of this study is to evaluate the resiliency and plan for future changes for New England fisheries and aquaculture ina rapidly changing ocean. Through field data collection, laboratory experiments, and stakeholder engagement, we will examinehow climate change will influence key fisheries and aquaculture species using a multi-pronged approach. First, we will examinehow climate will affect critical life history stages of key fisheries species by examining larval supply in New England waters andthe potential for a match-mismatch between larvae and their food sources.
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.
