Spatial Population Models In Spatiotemporally Structured Environments, David Hiebeler Nov 2011

Spatial Population Models In Spatiotemporally Structured Environments, David Hiebeler

University of Maine Office of Research Administration: Grant Reports

Spatial effects, such as habitat fragmentation and the location and size of disturbance events, play a key role in the dynamics of populations. This is true in natural populations (such as herbs living under a forest canopy) as well as human-dominated systems (for example, crop pests in agricultural landscapes). Focusing on the development of spatial population models, the project seeks to better understand how and why spatially autocorrelated disturbances affect the dynamics of populations with mixtures of short- and long-distance dispersal. A variety of disturbances are considered, including (1) static disturbance, representing habitat heterogeneity across a landscape; (2) short-term disturbance …


Collaborative Research: Microparticle/Tephra Analysis Of The Wais Divide Ice Core, Karl J. Kreutz, Andrei V. Kurbatov, Mark Wells, Paul Andrew Mayewski Sep 2011

Collaborative Research: Microparticle/Tephra Analysis Of The Wais Divide Ice Core, Karl J. Kreutz, Andrei V. Kurbatov, Mark Wells, Paul Andrew Mayewski

University of Maine Office of Research Administration: Grant Reports

This award supports a project to perform continuous microparticle concentration and size distribution measurements (using coulter counter and state-of-the-art laser detector methods), analysis of biologically relevant trace elements associated with microparticles (Fe, Zn, Co, Cd, Cu), and tephra measurements on the WAIS Divide ice core. This initial three-year project includes analysis of ice core spanning the instrumental (~1850-present) to mid- Holocene (~5000 years BP) period, with sample resolution ranging from subannual to decadal. The intellectual merit of the project is that it will help in establishing the relationships among climate, atmospheric aerosols from terrestrial and volcanic sources, ocean biogeochemistry, and …


It’S Growing Season For Maine’S Food System, Deborah Felder Jan 2011

It’S Growing Season For Maine’S Food System, Deborah Felder

Maine Policy Review

In the introduction to this special issue, guest editor Deb Felder lays out the elements of a sustainable food system. She notes that the increased interest in more ecologically sustainable, safe, humane, and economical community-supported food systems has “put Maine in the forefront of the food movement.”


Building A Sustainable Seafood System For Maine, Robin Alden Jan 2011

Building A Sustainable Seafood System For Maine, Robin Alden

Maine Policy Review

In this article, Robin Alden notes that Maine could have one of the premier marine food systems in the world. However, that means adequate steward­ship of the Gulf of Maine ecosystem and diversifying the fishing industry beyond lobster by creating innovative public policy and a food system that supports community fishing.


Farms And The Working Landscape, John Piotti Jan 2011

Farms And The Working Landscape, John Piotti

Maine Policy Review

After years of losing farms and farmers, Maine is seeing an increase in the number of acres being farmed, due partly to a resurgence of interest in farming and new tools that help preserve working landscapes. These tools include agricul­tural easements such as those offered by the Land for Maine’s Future, the Buy/Protect/Sell program at Maine Farmland Trust, local ordinances, and several federal programs
