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.
This project focuses on the economics of coping with decision environment anomalies through preparedness. Approaches to decision making in the presence of global anomalies and the economic implications for individual and collective preparedness will be investigated.
Recreational angling is a popular leisure activity for residents and visitors in Massachusetts, with one of the most sought after species being striped bass. Many of the striped bass are released following capture because of regulations and a growing conservation ethic among anglers, however little is known about how stresses associated with the capture event impacts behavior and survival.
Mitochondria are critical for production of ATP, the energy currency of a cell, but glucose utilization varies greatly among cell types. Inherited mitochondrial disorders affect neural tissues most prominently revealing the vulnerability of these tissues. In mice, prolonged exposure to mitochondrial toxins can lead to symptoms that mimic Parkinson's disease. The mammary gland is a tissue that, in its resting state, has relatively modest energy requirements.
Pitch pine-scrub oak barrens are a globally threatened, fire-dependent habitat that harbor numerous declining, rare, or imperiled plant and animal species. Threats to barrens include development, fragmentation, and fire exclusion which have reduced the extent of barrens communities to 10% of their original extent in western Massachusetts. Pitch pine-scrub oak (PPSO) forests are a significant contributor to the biodiversity of the Northeast.
Despite the significant efforts to reduce nitrogen discharge from wastewater treatment facilities (WWTFs), the Long Island Sound (LIS) area affected by hypoxia actually increased over the last decade. Our preliminary research has suggested that WWTFs utilizing the biological nitrogen removal (BNR) process may actually increase particular forms of N that are more potent for algal bloom in LIS. We propose a research plan to evaluate the true impact of upgrading WWTF for N removal (i.e., BNR) on receiving water eutrophication and toxic algal bloom.
The aim of this collaboration between the UMass College of Natural Sciences and the Massachusetts Envirothon is to encourage high school age young people to develop the science literacy, citizen skills, and knowledge of routes to further education and careers that will allow them to participate responsibly and effectively in natural resource conservation and land use decisions in Massachusetts communities.
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).
To increase resistance and resiliency to climate change, forest management practices will need to change to ensure species and structural diversity, and adjust to emerging threats, such as invasive species, pests and diseases. As a result of this need, there has been a flurry of development of science-based products and tools to incorporate the additional complexity of climate change and inform decisions about forest management and conservation.
Climate change is expected to increase the frequency and extent of future flood events in New England. Such events pose a substantial threat to both human and natural systems. Not only do the direct effects of extreme flooding harm human and ecosystems, but human responses in the lead up to and the aftermath of these events (such as forest and debris removal, channel alteration and armoring, and gravel mining) also create substantial disturbances. The effect of these human responses may be to alleviate or to exacerbate ecological damage and consequently the impacts of future flood events.
