Little research is available regarding energy use and sourcing decisions among lower-income households, particularly with respect to the efficacy of various behavioral interventions (e.g., providing social norms information; financial vs. social incentives). There is a similar lack of research that examines the barriers to and facilitators of lower-income households adopting small-scale renewable energy technologies (e.g., rooftop solar).

Municipalities worldwide are showing substantial interest in urban greening, defined here as the introduction or conservation of outdoor vegetation in cities. In many cases greening involves substantial tree planting, and across the United States cities have established ambitious canopy cover goals and major tree planting programs.
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.
Urbanizing watersheds in the northeastern United States face rapid changes in forest cover, urbanization, and conflicts in water use (USGS, 2002) that require careful evaluation of trends in components of the watershed system. This research will evaluate land use/land cover changes, assess their impacts on surface and groundwater supplies, and evaluate forest management strategies in a rapidly urbanizing watershed in southeastern Massachusetts.
There is widespread interest in greening municipalities and increasing urban tree canopy cover, largely through local community-based tree planting initiatives. It is generally estimated that newly-installed trees require at least 3 or more years before establishment, when they resume pre-transplant growth rates. Most trees installed in the urban environment are dug from the nursery field with a spade, and wrapped in burlap and a metal basket ('balled and burlap' or 'B&B').
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.
