Disentangling the Predation Paradox: Human Food Subsidies, Elevated Predator Densities, and Non-lethal Effects of Predators Along an Urbanization Gradient

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.

Spatial and Temporal Management of Forest Cover and Urban Impacts for Water Resources Sustainability

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.

Understanding Growth, Survival, & Maintenance Costs of Newly-established Urban Oak Trees, Produced Using Differing Nursery Methods.

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 Development and Assessment of Standardized Methodologies for Monitoring the Forest Ecosystem Indicator Species Plethodon Cinereus

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.

Deciding the Future of the Land: The Estate Planning Decisions of Family Forest Owners

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.

Global Invasive Plants: Using Spatial Patterns to Understand Invasion Risk to the Northeast

Invasive plants are species introduced from another region (non-native) that have established self-sustaining populations and are spreading, often with substantial negative consequences (Lockwood et al., 2007). Invasive species are a prominent component of global change (Vitousek et al., 1997, 1996), and have been identified as one of five major threats to ecosystems by the Millennium Ecosystem Assessment (along with, for example, climate change; MA, 2003).
