Geosensor Data Representation Using Layered Slope Grids Sensors., Yongmi Lee, Young Jin Jung, Kwang Woo Nam, Silvia Nittel Editor, Mary-Kate Beard-Tisdale, Keun Ho Ryu Dec 2012

Geosensor Data Representation Using Layered Slope Grids Sensors., Yongmi Lee, Young Jin Jung, Kwang Woo Nam, Silvia Nittel Editor, Mary-Kate Beard-Tisdale, Keun Ho Ryu

Publications

Environmental monitoring applications are designed for supplying derived and often integrated information by tracking and analyzing phenomena. To determine the condition of a target place, they employ a geosensor network to get the heterogeneous sensor data. To effectively handle a large volume of sensor data, applications need a data abstraction model, which supports the summarized data representation by encapsulating raw data. For faster data processing to answer a user’s queries with representative attributes of an abstracted model, we propose such a data abstraction model, the Layered Slopes in Grid for Sensor Data Abstraction (LSGSA), which is based on the SGSA. …

Mercury Bioaccumulation In Wood Frogs Developing In Seasonal Pools, Cynthia Loftin, Aram J K Calhoun, Sarah J. Nelson, Adria A. Elskus, Kevin Simon Dec 2012

Mercury Bioaccumulation In Wood Frogs Developing In Seasonal Pools, Cynthia Loftin, Aram J K Calhoun, Sarah J. Nelson, Adria A. Elskus, Kevin Simon

Publications

Seasonal woodland pools contribute significant biomass to terrestrial ecosystems through production of pool-breeding amphibians. The movement of amphibian metamorphs potentially transports toxins bioaccumulated during larval development in the natal pool into the surrounding terrestrial environment. We documented total mercury (THg) in seasonal woodland pool water, sediment, litter, and Lithobates sylvaticus LeConte (Wood Frog) in Acadia National Park, ME. THg concentrations in pool water varied over the study season, increasing during April-June and remaining high in 2 of 4 pools upon October refill. Water in pools surrounded by softwoods had lower pH, greater dissolved organic carbon, and greater THg concentrations than …

Does Green Consumerism Increase The Acceptance Of Wind Power?, Caroline L. Noblet, John Thøgersen Dec 2012

Does Green Consumerism Increase The Acceptance Of Wind Power?, Caroline L. Noblet, John Thøgersen

Publications

In this paper, we discuss what might be termed an action-based learning approach to promoting important pro-environmental actions, such as support for or acceptance of environmental policy. Such an approach involves promoting simple and easy behaviours as entry points for more radical steps towards sustainability, referred to as “catalytic” or “wedge” behaviours. Despite the obvious need for innovative approaches to promote important pro-environmental behaviour, and sound theoretical backing for such concepts, there is a lack of research testing the key propositions of this approach. In a survey study based on a random sample of residents of the state of Maine, …

Testing The Predictive Performance Of Distribution Models, Volker Bahn, Brian Mcgill Dec 2012

Testing The Predictive Performance Of Distribution Models, Volker Bahn, Brian Mcgill

Publications

Distribution models are used to predict the likelihood of occurrence or abundance of a species at locations where census data are not available. An integral part of modelling is the testing of model performance. We compared different schemes and measures for testing model performance using 79 species from the North American Breeding Bird Survey. The four testing schemes we compared featured increasing independence between test and training data: resubstitution, random data hold-out and two spatially segregated data hold-out designs. The different testing measures also addressed different levels of information content in the dependent variable: regression R2 for absolute abundance, squared …

Giving Voice To The Future In Sustainability: Retrospective Assessment To Learn Prospective Stakeholder Engagement, Mark W. Anderson, Mario F. Teisl, Caroline L. Noblet Oct 2012

Giving Voice To The Future In Sustainability: Retrospective Assessment To Learn Prospective Stakeholder Engagement, Mark W. Anderson, Mario F. Teisl, Caroline L. Noblet

Publications

There is a broad understanding that intergenerational equity is a necessary, if not sufficient, condition for sustainability. Likewise, there is a growing consensus that sustainability science requires stakeholder engagement to be successful. These two ideas demand some meaningful way of engaging the future as a stakeholder if sustainability is to be operationalized. Rawls' theory of justice provides a model for how this might be accomplished, yet there are both conceptual and practical problems with a Rawlsian approach. We propose using retrospective assessment as a means of learning how to approach future stakeholder engagement in sustainability.

Demographic Amplification Of Climate Change Experienced By The Contiguous United States Population During The 20th Century, Jason Samson, Dominique Berteaux, Brian Mcgill, Murray Humphries Oct 2012

Demographic Amplification Of Climate Change Experienced By The Contiguous United States Population During The 20th Century, Jason Samson, Dominique Berteaux, Brian Mcgill, Murray Humphries

Publications

Better understanding of the changing relationship between human populations and climate is a global research priority. The 20th century in the contiguous United States offers a particularly well-documented example of human demographic expansion during a period of radical socioeconomic and environmental change. One would expect that as human society has been transformed by technology, we would become increasingly decoupled from climate and more dependent on social infrastructure. Here we use spatially-explicit models to evaluate climatic, socio-economic and biophysical correlates of demographic change in the contiguous United States between 1900 and 2000. Climate-correlated variation in population growth has caused the U.S. …

Articulating Identity In And Through Maine's North Woods, Karen Hutchins, Nathan Stromer Mar 2012

Articulating Identity In And Through Maine's North Woods, Karen Hutchins, Nathan Stromer

Publications

Land-use changes can interrupt relationships to place, threaten community identity, and prompt instability, altering the social and physical context and impacting the present and future state of the social–ecological system. Approaches that map system changes are needed to understand the effects of natural resource decisions and human–nature interactions. In this article, we merge theories of articulation, the event, and symbolic territory into a critical framework to analyze online newspaper article responses and blogs referencing a land-use controversy in the State of Maine, USA. Application of this framework reveals land-use controversies as place-making events that alter contexts and sense of place, …

designing and implementing boundary management strategies, and highlights the complexities of direct engagement between scientists and policymakers and the implications of that engagement for scientists and their academic institutions. We draw from a case study conducted in Maine to argue that there are contexts in which the need arises for scientists to manage and span the science-policy boundary. The complexities involved in preparing scientists to engage more thoroughly in policy activities and the challenges in garnering institutional support for advancing the participation of scientists in boundary spanning activities are explored.

Impact Of Demographic Trends On Future Development Patterns And The Loss Of Open Space In The California Mojave Desert, Peter Gomben, Robert J. Lilieholm, Manuel Gonzalez-Guillen Feb 2012

Impact Of Demographic Trends On Future Development Patterns And The Loss Of Open Space In The California Mojave Desert, Peter Gomben, Robert J. Lilieholm, Manuel Gonzalez-Guillen

Publications

During the post-World War II era, the Mojave Desert Region of San Bernardino County, California, has experienced rapid levels of population growth. Over the past several decades, growth has accelerated, accompanied by significant shifts in ethnic composition, most notably from predominantly White non-Hispanic to Hispanic. This study explores the impacts of changing ethnicity on future development and the loss of open space by modeling ethnic propensities regarding family size and settlement preferences reflected by U.S. Census Bureau data. Demographic trends and land conversion data were obtained for seven Mojave Desert communities for the period between 1990 and 2001. Using a …

The Role Of Forest Harvesting And Subsequent Vegetative Regrowth, Viorel D. Popsedu, David A. Patrick, Malcolm L. Hunter Jr., Aram J K Calhoun Jan 2012

The Role Of Forest Harvesting And Subsequent Vegetative Regrowth, Viorel D. Popsedu, David A. Patrick, Malcolm L. Hunter Jr., Aram J K Calhoun

Publications

Conservation of forest-dependent amphibians is dependent on finding a balance between timber management and species’ habitat requirements. To examine the effect of short-term vegetative regrowth post-harvesting on amphibian habitat use, we studied the response of eight species (four forest specialists and four habitat generalists) to four forestry treatments (partial harvest, clearcut with coarse woody debris [CWD] removed, clearcut with CWD retained, and uncut control) over a 6-year period, using replicated experimental treatments in Maine, USA. Forest amphibians showed a strong negative response to clearcutting through the duration of the study, regardless of the presence of CWD, but only during the …

Socialization To Interdisciplinary: Faculty And Student Perspectives, Susan K. Gardner, Jessica Spelke Jansujwicz, Karen Hutchins, Brittany Cline, Vanessa Levesque Jan 2012

Socialization To Interdisciplinary: Faculty And Student Perspectives, Susan K. Gardner, Jessica Spelke Jansujwicz, Karen Hutchins, Brittany Cline, Vanessa Levesque

Publications

Interdisciplinary research and education are a growing emphasis in United States institutions of higher education but relatively little is known about the doctoral students engaged in these atypical programs. The purpose of this study was to understand the socialization process of 18 students involved in a large-scale, federally funded, interdisciplinary research project focused on sustainability at one university. Using Weidman, Twale, and Stein’s framework of graduate student socialization, themes emerged related to (a) their distinctive characteristics and cultures, (b) the learning process, (c) balance, (d) uncertainty, and (d) support. Recommendations for policy and practice are included.

Critical Habitat And The Challenge Of Regulating Small Harms., Dave Owen Jan 2012

Critical Habitat And The Challenge Of Regulating Small Harms., Dave Owen

Publications

This Article investigates how the U.S. Fish and Wildlife Service, the National Marine Fisheries Service, and the courts are implementing the Endangered Species Act’s prohibition on “adverse modification” of “critical habitat.” That prohibition appears to be one of environmental law’s most ambitious mandates, but its actual meaning and effect are contested. Using a database of over 4,000 “biological opinions,” interviews with agency staff, and a review of judicial decisions considering the adverse modification prohibition, this Article assesses the extent to which the Fish and Wildlife Service, the National Marine Fisheries Service, and the courts are relying on the adverse modification …

Emergent Behavior In A Coupled Economic And Coastline Model For Beach Nourishment, Eli D. Lazarus, D E. Mcnamara, M D. Smith, S Gopalakrishnan, A B. Murray Dec 2011

Emergent Behavior In A Coupled Economic And Coastline Model For Beach Nourishment, Eli D. Lazarus, D E. Mcnamara, M D. Smith, S Gopalakrishnan, A B. Murray

Publications

Developed coastal areas often exhibit a strong systemic coupling between shoreline dynamics and economic dynamics. "Beach nourishment", a common erosion-control practice, involves mechanically depositing sediment from outside the local littoral system onto an actively eroding shoreline to alter shoreline morphology. Natural sediment-transport processes quickly rework the newly engineered beach, causing further changes to the shoreline that in turn affect subsequent beach-nourishment decisions. To the limited extent that this landscape/economic coupling has been considered, evidence suggests that towns tend to employ spatially myopic economic strategies under which individual towns make isolated decisions that do not account for their neighbors. What happens …

Algal Bioassessment Metrics For Wadeable Streams And Rivers Of Maine, Usa, Thomas J. Danielson, Cynthia Loftin, Leonidas Tsomides, Jeanne L. Difranco, Beth Connors Sep 2011

Algal Bioassessment Metrics For Wadeable Streams And Rivers Of Maine, Usa, Thomas J. Danielson, Cynthia Loftin, Leonidas Tsomides, Jeanne L. Difranco, Beth Connors

Publications

Many state water-quality agencies use biological assessment methods based on lotic fish and macroinvertebrate communities, but relatively few states have incorporated algal multimetric indices into monitoring programs. Algae are good indicators for monitoring water quality because they are sensitive to many environmental stressors. We evaluated benthic algal community attributes along a landuse gradient affecting wadeable streams and rivers in Maine, USA, to identify potential bioassessment metrics. We collected epilithic algal samples from 193 locations across the state. We computed weighted-average optima for common taxa for total P, total N, specific conductance, % impervious cover, and % developed watershed, which included …

Clearcutting Has A Long-Lasting Effect On Habitat Connectivity For A Forest Amphibian By Decreasing Permeability To Juvenile Movements, Viorel Popescu, Malcolm L. Hunter Jr. Jun 2011

Clearcutting Has A Long-Lasting Effect On Habitat Connectivity For A Forest Amphibian By Decreasing Permeability To Juvenile Movements, Viorel Popescu, Malcolm L. Hunter Jr.

Publications

Conservation of forest amphibians is dependent on finding the right balance between management for timber production and meeting species' habitat requirements. For many pond-breeding amphibians, successful dispersal of the juvenile stage is essential for long-term population persistence. We investigated the influence of timber-harvesting practices on the movements of juvenile wood frogs (Lithobates sylvaticus). We used a chronosequence of stands produced by clear-cutting to evaluate how stand age affects habitat permeability to movements. We conducted experimental releases of juveniles in 2008 (n = 350) and 2009 (n = 528) in unidirectional runways in four treatments: mature forest, recent clearcut, …

Using Bayesian Belief Networks To Identify Potential Compatibilities And Conflicts Between Development And Landscape Conservation, Jon T. Mccloskey May 2011

Using Bayesian Belief Networks To Identify Potential Compatibilities And Conflicts Between Development And Landscape Conservation, Jon T. Mccloskey

Publications

Experts with different land use interests often use differing definitions of land suitability that can result in competing land use decisions. We use Bayesian belief networks linked to GIS data layers to integrate empirical data and expert knowledge from two different land use interests (development and conservation) in Maine’s Lower Penobscot River Watershed. Using ground locations and digital orthoquads, we determined the overall accuracy of the resulting development and conservation suitability maps to be 82% and 89%, respectively. Overlay of the two maps show large areas of land suitable for both conservation protection and economic development and provide multiple options …

Urbanization, Water Quality, And The Regulated Landscape, Dave Owen Apr 2011

Urbanization, Water Quality, And The Regulated Landscape, Dave Owen

Publications

Watershed scientists frequently describe urbanization as a primary cause of water quality degradation, and recent studies conclude that even in lightly-developed watersheds, urbanization often precludes attainment of water quality standards. This article considers legal responses to this pervasive problem. It explains why traditional legal measures have been ineffective, and it evaluates several recent innovations piloted in the northeastern United States and potentially applicable across the nation. Specifically, the innovations involve using impervious cover TMDLs, residual designation authority, and collective permitting. More generally, the innovations involve transferring regulatory focus from end-of-the-pipe to landscape-based controls. I conclude that the innovations, while raising …

Publications

Anticipating the effects of climate change on biodiversity is now critical for managing wild species and ecosystems. Climate change is a global driver and thus affects biodiversity globally. However, land-use planners and natural resource managers need regional or even local predictions. This provides scientists with formidable challenges given the poor documentation of biodiversity and its complex relationships with climate. We are approaching this problem in Quebec, Canada, through the CC-Bio Project (http://cc‑bio.uqar.ca/), using a boundary organization as a catalyst for team work involving climate modelers, biologists, naturalists, and biodiversity managers. In this paper we present the CC-Bio Project and its …

Collaboration, Clean Water Act Residual Designation Authority, And Collective Permitting: A Case Study Of Long Creek, Dave Owen, Curtis Bohlen, Peter H. Glaser, Zach Henderson, Christopher Kilian

Publications

Water quality degradation in urban watersheds is a pervasive problem, and many urban waterways fail to attain water quality standards set pursuant to the Clean Water Act. Finding mechanisms to close this gap has proven difficult. As traditionally implemented, none of the Clean Water Act’s primary mechanisms for addressing urban water quality has offered consistent and effective solutions. This article discusses an innovative effort to develop an alternative approach. To address degradation of Long Creek, a small urban stream in southern Maine, regulators used the residual designation authority created by Section 402(p) of the Clean Water Act to substantially expand …

A Multi-Scale Assessment Of Amphibian Habitat Selection: Wood Frog Response To Timber Harvesting, Sean Michael Blomquist, Malcolm L. Hunter Jr. Sep 2010

A Multi-Scale Assessment Of Amphibian Habitat Selection: Wood Frog Response To Timber Harvesting, Sean Michael Blomquist, Malcolm L. Hunter Jr.

Publications

To understand changes in habitat selection in response to timber harvesting, we used radio-telemetry data from 82 adult wood frogs (Lithobates sylvaticus, formerly Rana sylvatica) and logistic regression modelling to assess habitat selection in response to an unharvested control and 3 forest management techniques: clearcutting (with removal of all merchantable timber > 10 cm diameter), clearcutting with coarse woody debris (CWD) retention, and partial harvesting with retention of ∼50% canopy cover. At the home range scale, frogs selected the partially harvested treatment in spring 2005 and avoided the CWD-retained treatment in fall 2006. Frogs spent 5 ± 2 d (mean ± …

Despite a growing recognition that the solutions to current environmental problems will be developed through collaborations between scientists and stakeholders, substantial challenges stifle such cooperation and slow the transfer of knowledge. Challenges occur at several levels, including individual, disciplinary, and institutional. All of these have implications for scholars working at academic and research institutions. Fortunately, creative ideas and tested models exist that provide opportunities for conversation and serious consideration about how such institutions can facilitate the dialogue between scientists and society.

Forest Biomass Harvesting In The Northeast: A Special-Needs Operation?, Jeffrey Benjamin, Robert J. Lilieholm, Charles E. Coup Jun 2010

Forest Biomass Harvesting In The Northeast: A Special-Needs Operation?, Jeffrey Benjamin, Robert J. Lilieholm, Charles E. Coup

Publications

There is growing interest in harvesting forest biomass to meet the needs of bioenergy and bioproducts facilities in the Northeast. This interest is accompanied by increased concern over the potential impacts of biomass removals on forest ecosystems. Debates over biomass proposals have revealed a considerable level of confusion over the term biomass harvest, much of which stems from ambiguity surrounding the term forest biomass. Indeed, all forest material removed during harvest is forest biomass, yet many view only a small portion of this—typically low-value chipped material—as biomass. Since much of this material is destined for use as energy, we feel …

Community Attitudes Toward Wildlife And Protected Areas In Ethiopia, Mekbeb E. Tessema, Robert J. Lilieholm, Zelealem T. Ashenafi, Nigel Leader-Williams May 2010

Community Attitudes Toward Wildlife And Protected Areas In Ethiopia, Mekbeb E. Tessema, Robert J. Lilieholm, Zelealem T. Ashenafi, Nigel Leader-Williams

Publications

Across Africa, national policies that established protected areas (PAs) typically limited local use of wildlife and other resources. Over time, these policies have raised tensions with rural communities and today threaten to undermine conservation goals. This article examines community–PA relationships at four important sites in Ethiopia—a country of rich tradition with an unusual colonial past. Using focus groups and household surveys, we found that despite local tensions, most respondents held positive views toward wildlife and nearby PAs. Factors influencing positive views included receiving PA benefits, good relations with PA staff, higher education levels, being older, having a large family, diversified …

Does A Property‐Specific Environmental Health Risk Create A “Neighborhood” Housing Price Stigma? Arsenic In Private Well Water, Kevin Boyle, Nicolai Kuminoff, Congwen Zhang, Michael Devanney, Kathleen Bell

Publications

This paper examines the impact of arsenic contamination of groundwater on sale prices of residential properties and bare land transactions in two Maine towns, Buxton and Hollis, that rely on private wells to supply their drinking water. Prompted by tests of well water by the state of Maine, media attention focused on the communities in 1993 and 1994 when 14% of private wells were found to have arsenic concentrations exceeding the U.S. Environmental Protection Agency standard of 0.05 mg/L. Households could mitigate the serious health risks associated with arsenic ingestion by purchasing bottled water or by installing a reverse osmosis …

Comparing Relative Abundance Of Amphibians In Forest Canopy Gaps Of Natural Origin Vs. Timber Harvest Origin, Carol J. Strojny, Malcolm L. Hunter Jr. Jan 2010

Comparing Relative Abundance Of Amphibians In Forest Canopy Gaps Of Natural Origin Vs. Timber Harvest Origin, Carol J. Strojny, Malcolm L. Hunter Jr.

Publications

Relative abundance of amphibians in forest canopy gaps of natural origin vs. timber harvest origin.— Small–scale canopy gaps created by logging may retain adequate habitat structure to maintain amphibian abundance. We used pitfalls with drift fences to measure relative abundance of amphibians in 44 harvested gaps, 19 natural treefall gaps, and 36 closed–canopy forest plots. Metamorphs had relatively lower capture rates in large harvest gaps for Ambystoma maculatum, Lithobates catesbeianus, L. clamitans, and L. sylvaticus but we did not detect statistically significant (p < 0.1) differences among gap types for Lithobates palustris metamorphs. L. clamitans juveniles and L. sylvaticus juveniles and adults had relatively …

The Psychology Of Eco-Consumption., Mario F. Teisl, Caroline L. Noblet, Jonathan Rubin

Publications

Information programs to promote cellulosic biofuels may not achieve their objectives unless consumers can be induced to care about the information presented to them. The social psychology literature highlights two commonly used models to link psychological variables to environmentally related behaviors: the Theory of Planned Behavior (TPB) and the Norm Activation Theory (NAT). Other studies have compared the strength of these models or have adapted these models by adding additional variables, but few have compared across the alternative variable combinations noted in the literature. That is, most studies have added one or two psychological variables to the NAT or TPB …

Challenges And Opportunities For The Northeastern Forest Bioindustry, Jeffrey Benjamin, Robert J. Lilieholm, David Damery

Publications

Given the interest in renewable energy sources across the United States, it is likely that biomass harvested directly from the forest will play an important role in creating and sustaining the forest bioindustry. This article shows that the Northeastern Region’s strengths (abundant forest resources and an established forest sector) provide the framework for a sustainable and viable forest bioindustry. Careful consideration must also be given to existing infrastructure, resource conditions, forest operations, public policy, and the wide range of social values likely to emerge as the industry grows. Challenges that must be addressed include improvements to the overall condition of …

Resource Use, Dependence And Vulnerability: Community-Resource Linkages On Alaska’S Tongass National Forest, Mekbeb E. Tessema, Robert J. Lilieholm, L. E. Kruger

Publications

Understanding how rural communities use and depend upon local natural resources is a critical factor in developing policies to sustain the long-term viability of human and natural systems. Such “community-resource” linkages are particularly important in Alaska, where rural communities – many of them comprised of indigenous Alaskan Natives – are highly dependent upon local resources found on public lands. Alaskan communities utilize forests in many ways. To better understand these coupled “social-ecological” systems, we combined socio-economic data from the 2000 U.S. Census with timber permit data from the USDA Forest Service to describe communities and their use of forest resources. …
