Quantifying spatial and temporal heterogeneity in ecosystem processes presents a challenge for conserving ecosystem function across landscapes. In particular, many ecosystems contain small features that play larger roles in ecosystem processes than their size would indicate; thus, they may represent ‘‘hotspots’’ of activity relative to their surroundings. Biogeochemical hotspots are characterized as small features within a landscape that show comparatively high chemical reaction rates. In northeastern forests in North America, vernal pools are abundant, small features that typically fill in spring with snow melt and precipitation and dry by the end of summer. Ephemeral flooding alters soil moisture and the …
Trading Fat For Forests: On Palm Oil, Tropical Forest Conservation, And Rational Consumption, Cindy Isenhour
Trading Fat For Forests: On Palm Oil, Tropical Forest Conservation, And Rational Consumption, Cindy Isenhour
Anthropology Faculty Scholarship
The longstanding butter vs margarine debate has recently become more complex as the links between margarine, industrial palm oil plantations, and tropical deforestation are made increasingly clear. Yet despite calls for consumers to get informed and take responsibility for tropical deforestation by boycotting margarine or purchasing buttery spreads made with sustainably-sourced palm oil, research in multiple contexts demonstrates that even the most aware, engaged, and rational consumers run into significant barriers when trying to reduce their environmental impacts. This paper supplements important critiques of neoliberal conservation at the site of extraction or intended conservation (Carrier and West 2009; Igoe and …

Reu Site: Explore It! Building The Next Generation Of Sustainable Forest Bioproduct Researchers, David J. Neivandt, Darrell W. Donahue
University of Maine Office of Research Administration: Grant Reports
This three-year REU Site program builds on the substantial research strengths at the University of Maine. The focus on sustainable forest bioproducts is highly topical and of great global importance in the area of sustainable energy alternatives.
Ten US undergraduate participants will conduct research advancing their knowledge of the field in general and one of the thematic elements in detail, specifically:
1) sustainability and life cycle analysis,
2) feedstock extraction/modification,
3) process control and sensing,
4) nanomaterial production and utilization, and
5) new product development. In addition the program includes an international component whereby, six Chilean students on a mutual …

Collaborative Research: Interactive Effects Of Chronic N Deposition, Acidification, And Phosphorus Limitation On Coupled Element Cycling In Streams, Kevin S. Simons, Ivan J. Fernandez, Stephen A. Norton
Collaborative Research: Interactive Effects Of Chronic N Deposition, Acidification, And Phosphorus Limitation On Coupled Element Cycling In Streams, Kevin S. Simons, Ivan J. Fernandez, Stephen A. Norton
University of Maine Office of Research Administration: Grant Reports
The overarching goal of this project is to understand how chronic acidification and nitrogen enrichment of watersheds influences coupled biogeochemical cycling in streams. Embedded in the project were two primary research elements: 1) examining nitrogen satuartion and the extent of coupling between nitrogen and phosphorus cycling and 2) resolving the interactions among acidification, phosphorus bioavailability and biotic demand for nitrogen and phosphorus. The research involved a series of stable isotope tracer experiments to document nitrogen uptake under ambient and elevated phosphrous conditions and examination of a suite of key microbial processes (denitrification, decomposition, microbial enzyme activity) at two whole-watershed experiment …
Managing The Middle Ground: Forests In The Transition Zone Between Cities And Remote Areas, Charles Colgan, Malcolm L. Hunter Jr., Aaron Weiskittel, Brian Mcgill
Managing The Middle Ground: Forests In The Transition Zone Between Cities And Remote Areas, Charles Colgan, Malcolm L. Hunter Jr., Aaron Weiskittel, Brian Mcgill
Publications
In many parts of the world there are extensive landscapes where forests and people strongly intermingle, notably in the suburbs and exurbs of cities. This landscape of transitional forest generally receives limited attention from policy makers and researchers who tend to be rooted in traditions centered on either urban planning or management of natural resources in rural areas. The transitional forest is on the periphery of both perspectives, but it is a large area that provides numerous important values (biodiversity, ecosystem function, forest products, and amenities) to the people that live in them and their neighboring cities. Here we argue …

Kennebec Valley Community College Pulp And Paper Technology Program, Hemant P. Pendse
University of Maine Office of Research Administration: Grant Reports
The program was sponsored by the National Science Foundation to support the development of an advanced technical workforce in the U.S. Topics covered included pulp preparation, handsheet making, and paper testing. The future of the industry and topics such as biofuels and ‘smart packaging’ were also discussed. Hands-on lab exercises were performed at the Process Development Center, a state-of-the-art facility in the Department of Chemical and Biological Engineering.

Forest - Atmosphere Interaction At Howland Forest, David Dail
Forest - Atmosphere Interaction At Howland Forest, David Dail
University of Maine Office of Research Administration: Grant Reports
The overall goal of the proposed work is to understand the various (and interacting) impacts of a changing climate on carbon cycling at the Howland AmeriFlux site, representative of an important component of the North American boreal forest. Our focus is on quantitatively partitioning respiration into aboveground and belowground processes and into autotrophic and heterotrophic processes to better constrain carbon cycle models. Whole-ecosystem flux measurements generally do a poor job of separating photosynthetic uptake from respiration and cannot constrain (or assign) respiration to the different sources within an ecosystem. This partitioning is difficult, but we will take advantage of new …

Fragmentation Of The Kitengela Ecosystem, Kenya, Robert Lilieholm
University of Maine Office of Research Administration: Grant Reports
Gypsum mines develop into water ponds which attract livestock and wildlife to drink water. The soil is sticky, slippery and unstable; there is loss of wildlife and herders' normally loose livestock in the process as they get trapped while drinking water. The water ponds have fish which has attracted fishermen from other areas...wildlife/livestock and local communities compete for water resources from L. Jipe. The shoats were driven away by elephants. Women who were fetching water literally ran away when the elephants approached. Watering places are good sites for livestock predation too.
