Spatial Aspects Of Tree Mortality Strongly Differ Between Young And Old-Growth Forests, Andrew J. Larson, James A. Lutz, Daniel C. Donato, James A. Freund, Mark E. Swanson, Janneke Hillrislambers, Douglas G. Sprugel, Jerry F. Franklin

Forest Management Faculty Publications

Rates and spatial patterns of tree mortality are predicted to change during forest structural development. In young forests, mortality should be primarily density dependent due to competition for light, leading to an increasingly spatially uniform pattern of surviving trees. In contrast, mortality in old-growth forests should be primarily caused by contagious and spatially auto-correlated agents (e.g., insects, wind), causing spatial aggregation of surviving trees to increase through time. We tested these predictions by contrasting a three-decade record of tree mortality from replicated mapped permanent plots located in young (<60-year-old) and old-growth (>300-year-old) Abies amabilis forests. Trees in young forests died at a …

Quantifying The Effects Of Biomass Market Conditions And Policy Incentives On Economically Feasible Sites To Establish Dedicated Energy Crops, Sandhya Nepal, Marco A. Contreras, George A. Stainback, John M. Lhotka

Forestry and Natural Resources Faculty Publications

This study used a spatially-explicit model to identify the amount and spatial distribution of economically feasible sites for establishing dedicated energy crops under various market and policy scenarios. A sensitivity analysis was performed for a biomass market with different discount rates and biomass prices as well as policy scenarios including propriety tax exemption, carbon offset payments, and the inclusion of farmland for biomass production. The model was applied to a four-county study area in Kentucky representing conditions commonly found in the Ohio River Valley. Results showed that both biomass price and discount rate have a can strongly influence the amount …

Economic Contribution Of Agriculture And Food To Arkansas' Gross Domestic Product 1997-2013, Leah English, Jennie Popp, Wayne Miller

AAES Research Reports and Research Bulletins

Agricultural production, processing, and retail industries are major contributors to the Arkansas economy in terms of GDP. Agriculture contributes to the economy through direct agricultural production, value-added processing, and agricultural retail activities, and it also plays an important role through its interactions with other sectors. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy; thus agriculture remains a vital part of Arkansas’ economy. This report: 1) compares the relative size of the Agriculture and Food Sector in Arkansas with those of neighboring states; 2) provides an overview of Arkansas’ economy …

An Avian Biological Gradient Across Tropical Dry Lowland Local Habitats At Playa Venao, Los Santos Province, Panama, Abigail Thomas

Independent Study Project (ISP) Collection

There are a myriad of forest types within Panama, varying by elevation, precipitation and other abiotic factors, which hosts a wide variety of native and migratory species in uniquely-structured avian communities. Panama has been well assessed for presence and distribution of its 987 collective avian species (Angehr, 2014). However most studies in Panama have been broad in scope, overlooking the highly specified habitats that are uniquely structured to host a certain range of avifauna communities. The distinctions in community structure of avifauna along a coastal to inland gradient were assessed among three specialized habitats: the Central Pacific coast, partially deforested …

Evaluating The Use Of Tree Shelters For Direct Seeding Of Castanea On A Surface Mine In Appalachia, Christopher Barton, Jarrod Miller, Kenton L. Sena, Patrick Angel, Michael French

Forestry and Natural Resources Faculty Publications

American chestnut (Castanea dentata), once a primary constituent of the eastern hardwood forest ecosystem, was nearly extirpated from the forest canopy by the accidental introduction of chestnut blight (Cryphonectria parasitica). An intensive breeding program has sought to breed blight resistance from Chinese chestnut into American chestnuts, while maintaining as much of the desirable American chestnut phenotypes as possible. Previous studies suggest that these blight resistant American chestnuts, termed “restoration chestnuts”, are capable of thriving on reclaimed surface mines. We direct seeded pure Chinese, pure American, and three backcross lines into brown sandstone minesoil on a mine …

Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain

Virginia Journal of Science

The Virginia landscape supports a remarkable diversity of forests, from maritime dune woodlands, swamp forests, and pine savannas of the Atlantic Coastal Plain, to post-agricultural pine-hardwood forests of the Piedmont, to mixed oak, mesophytic, northern hardwood, and high elevation spruce-fir forests across three mountain provinces in western parts of the state. Virginia’s forests also have been profoundly shaped by disturbance. Chestnut blight, hemlock woolly adelgid, emerald ash borer, and other pests have caused declines or functional extirpation of foundation species. Invasive plants like multiflora rose, Oriental bittersweet, and Japanese stiltgrass threaten both disturbed and intact forests. Oaks and other fire-dependent …

Assessing The Sustainability Of Selective Logging In Ankarabolava-Agnakatrika New Protected Area, Eileen Nakahata

Independent Study Project (ISP) Collection

Over the past 50 years, more than 90% of dense low-altitude humid forest in the District of Vangaindrano has been lost to deforestation and the remaining fragments continue to be threatened by slash and burn agriculture and selective cutting by local populations. These activities are driven by widespread poverty, population growth, and lack of development, which have made subsistence increasingly difficult. This study investigates logging rates and the stock of five commercially valuable trees in the Ankarabolava-Agnakatrika New Protected Area. Fifteen 1000m² transects were established systematically within the territory of the Matanga commune. Within each transect data was collected …

Heterogeneous Oxidation Of Catechol, Elizabeth A. Pillar, Ruixin Zhou, Marcelo I. Guzman

Chemistry Faculty Publications

Natural and anthropogenic emissions of aromatic hydrocarbons from biomass burning, agro-industrial settings, and fossil fuel combustion contribute precursors to secondary aerosol formation (SOA). How these compounds are processed under humid tropospheric conditions is the focus of current attention to understand their environmental fate. This work shows how catechol thin films, a model for oxygenated aromatic hydrocarbons present in biomass burning and combustion aerosols, undergo heterogeneous oxidation at the air–solid interface under variable relative humidity (RH = 0–90%). The maximum reactive uptake coefficient of O₃(g) by catechol γ_O3 = (7.49 ± 0.35) × 10^–6 occurs for …

Modeling Wood Fibre Length In Black Spruce (Picea Mariana (Mill.) Bsp) Based On Ecological Land Classification, Elisha Townshend, Bharat Pokharel, Art Groot, Doug Pitt, Jeffery P. Dech

Agricultural and Environmental Sciences Faculty Research

Effective planning to optimize the forest value chain requires accurate and detailed information about the resource; however, estimates of the distribution of fibre properties on the landscape are largely unavailable prior to harvest. Our objective was to fit a model of the tree-level average fibre length related to ecosite classification and other forest inventory variables depicted at the landscape scale. A series of black spruce increment cores were collected at breast height from trees in nine different ecosite groups within the boreal forest of northeastern Ontario, and processed using standard techniques for maceration and fibre length measurement. Regression tree analysis …
