Reu Site: Explore It! Building The Next Generation Of Sustainable Forest Bioproduct Researchers, David Neivandt, Darrell W. Donahue

University of Maine Office of Research Administration: Grant Reports

The major goal of the project is to create the next generation of sustainable forest bioproduct researchers through providing them with an outstanding and relevant research experience.

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

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 …

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.
