Influence Of Silvicultural Treatment, Site Characteristics, And Land Use History On Native And Nonnative Forest Understory Plant Composition On The Penobscot Experimental Forest In Maine, Elizabeth Bryce
Electronic Theses and Dissertations
This study investigates forest understory plant diversity and composition in managed and unmanaged stands within the context of a long-term silvicultural experiment in the Acadian Forest of Maine. I examined the effects of silvicultural intensity and past land use on understory plant species diversity and composition. Silvicultural treatments include three variants of the selection system, three variants of the shelterwood system, modified and fixed diameter-limit cutting, and an unregulated harvest. Two types of unmanaged stands were studied: a continuously forested natural area and secondary forest stands on old fields. Chapter 1 presents analysis of understory plant diversity and composition in …
The Chemistry Of Acidic Soils In Humid, Temperate Forested Watersheds With Emphasis On Phosphorus, Aluminum And Iron, Micheal Sanclements
The Chemistry Of Acidic Soils In Humid, Temperate Forested Watersheds With Emphasis On Phosphorus, Aluminum And Iron, Micheal Sanclements
Electronic Theses and Dissertations
Acidification of soils can result from natural processes (i.e. pedogenesis) and from atmospherically derived sulfur (S) and nitrogen (N) which originate from anthropogenic emissions. Research on the effects of acidification has typically focused on base cations, N and aluminum (Al). The Bear Brook Watershed in Maine (BBWM) (a long-term, whole-watershed acidification experiment) demonstrated increased episodic stream export of Al, iron (Fe), and phosphorus (P) in the treated watershed, suggesting that acidification can also affect P. This research evaluates (a) the physical and chemical distribution of P, (b) mechanisms controlling soil P accumulation, mobilization, and availability in humid, temperate forested ecosystems, …
Conservation Implications Of A Marbled Salamander, Ambystoma Opacum, Metapopulation Model, Ethan B. Plunkett
Conservation Implications Of A Marbled Salamander, Ambystoma Opacum, Metapopulation Model, Ethan B. Plunkett
Masters Theses 1911 - February 2014
Amphibians are in decline globally and a significantly greater percentage of ambystomatid salamander species are in decline relative to other species; habitat loss contributes significantly to this decline. The goals of this thesis is to better understand extinction risk in a marbled salamander (ambystoma opacum) population and how forestry effects extinction risk. To achieve this goal we first estimated an important life history parameter (Chapter 1) then used a metapopulation model to estimate population viability and determine what aspects of their life history put them most at risk (Chapter 2) and finally predicted extinction risk in response to hypothetical forestry …

Species Vs. Height As Predictors Of Increased Growth Rate In New England Canopy Trees, Kiely Schultz
Species Vs. Height As Predictors Of Increased Growth Rate In New England Canopy Trees, Kiely Schultz
Honors Projects
As part of a larger study on the effect of an experimentally-created gap within a forest on adult canopy trees, focuses on the possible effect of tree height versus type of species on radial growth response to gap creation. Sample includes fifty trees within four transects next to a gap in the Yale-Myers Experimental Forest in Connecticut, with results showing that type of species affects radial growth response.
