Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie 2016 University of Southern Mississippi

Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie

Master's Theses

The Zuni Mountains are a region that has been dramatically changed by human interference. Anthropogenically, fire suppression practices have allowed a buildup of fuels and caused a change in the fire-adapted ponderosa pine ecosystem such that the new ecosystem now incorporates many fire-intolerant species. As a result, the low-severity fires that the ecosystem once depended on to regenerate the forest are much reduced, and these low-severity fires are now replaced by crown-level infernos that threaten the forest and nearby towns. In order to combat these effects, land managers are implementing fuel reduction practices and are striving to better understand the ...


An Investigation Of Hydrogeologic, Stratigraphic, And, Melinda S. Faulkner 2016 Stephen F Austin State University

An Investigation Of Hydrogeologic, Stratigraphic, And, Melinda S. Faulkner

Electronic Theses and Dissertations

The Owl Mountain Province is located within the Fort Hood Military Installation, an approximately 880 km2 installation established in the 1940s in Bell and Coryell counties, Texas, which has undergone extensive land use changes associated with military training, maintaining much of the vegetation in early succession. This study investigates thelithologic, stratigraphic, and structural controls on the hydrologic, hydrogeologic, and geomorphologic evolution of the Owl Mountain Province as expressed by mesic vegetation communities, including Pleistocene relicts Acer grandidentatum, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the Neogene ...


Nitrogen Addition Shapes Soil Phosphorus Availability In Two Reforested Tropical Forests In Southern China, Xiankai Lu, Jiangming Mo, Frank S. Gilliam, Hua Fang, Feifei Zhu, Yunting Fang, Wei Zhang, Juan Huang 2016 Marshall University

Nitrogen Addition Shapes Soil Phosphorus Availability In Two Reforested Tropical Forests In Southern China, Xiankai Lu, Jiangming Mo, Frank S. Gilliam, Hua Fang, Feifei Zhu, Yunting Fang, Wei Zhang, Juan Huang

Frank S. Gilliam

Scant information is available on how soil phosphorus (P) availability responds to atmospheric nitrogen (N) deposition, especially in the tropical zones. This study examined the effect of N addition on soil P availability, and compared this effect between forest sites of contrasting land-use history. Effects of N addition on soil properties, litterfall production, P release from decomposing litter, and soil P availability were studied in a disturbed (reforested pine forest with previous understory vegetation and litter harvesting) and a rehabilitated (reforested mixed pine/broadleaf forest with no understory vegetation and litter harvesting) tropical forest in southern China. Experimental N-treatments (above ...


Evaluation Of Three Cropping Systems Grown Under The Influence Of A Shelterbelt, Carl W. Mize, Arne Hallam, Richard M. Cruse 2016 Iowa State University

Evaluation Of Three Cropping Systems Grown Under The Influence Of A Shelterbelt, Carl W. Mize, Arne Hallam, Richard M. Cruse

Arne Hallam

Shelterbelts have the potential to influence growth and yield from various cropping systems. On-farm tests were conducted to determine how shelterbelts interacted with corn, corn/soybean, and strip intercropping.


Interspecific Divergence In Foliar Nutrient Dynamics And Stem Growth In A Temperate Forest In Response To Chronic Nitrogen Inputs, Jeffrey D. May, Sarah Beth Burdette, Frank S. Gilliam, Mary Beth Adams 2016 Marshall University

Interspecific Divergence In Foliar Nutrient Dynamics And Stem Growth In A Temperate Forest In Response To Chronic Nitrogen Inputs, Jeffrey D. May, Sarah Beth Burdette, Frank S. Gilliam, Mary Beth Adams

Jeffrey May

We studied the effects of excessive nitrogen (N) fertilization on foliar nutrient dynamics and stem growth in three important tree species in a mixed-deciduous forest. Stem diameter growth, foliar N concentrations, nitrogen–phosphorus (N/P) ratios, and nutrient resorption were determined for Acer rubrum L. (ACRU), Liriodendron tulipifera L. (LITU), and Prunus serotina Ehrh. (PRSE) on two 30-year-old watersheds at the Fernow Experimental Forest, West Virginia, USA: WS3, fertilized annually with 35 kg ammonium sulfate·ha-1 since 1989, and WS7, an untreated control watershed. In an earlier (1992) study, foliar N concentrations of all three species averaged 11% higher ...

Forests In Flux: The Effects Of Demographic Change On Forest Cover In New England And New York, Mark J. Ducey, Kenneth M. Johnson, Ethan P. Belair, Miranda H. Mockrin 2016 University of New Hampshire - Main Campus

Forests In Flux: The Effects Of Demographic Change On Forest Cover In New England And New York, Mark J. Ducey, Kenneth M. Johnson, Ethan P. Belair, Miranda H. Mockrin

The Carsey School of Public Policy at the Scholars' Repository

This brief contributes to a better understanding of the linkages between demographic and forest cover change so as to inform policy efforts aimed at maintaining existing forested areas in and around sprawling urban centers. Authors Mark Ducey, Kenneth Johnson, Ethan Belair, and Miranda Mockrin report that forest cover has declined throughout New England and New York over the last decade. In rural areas, forest loss is primarily due to commercial timber harvesting and represents a temporary change. Conversely, forest cover decline in urban areas is usually the result of development and is likely to be permanent. Forest cover change is ...

The Impacts Of Elephant Grazing On Plant Succession In Tropical Forests Of Africa, Nadia Swit 2016 Cleveland State University

The Impacts Of Elephant Grazing On Plant Succession In Tropical Forests Of Africa, Nadia Swit

The Downtown Review

Succession occurs in an ecosystem when there is a change in the species structure and diversity in an ecological community over time. While this can allow for greater biodiversity, occasionally diversity can be stunted based on the level of disturbance and the invasiveness of the first pioneering species. As in the case of arrested succession, continual disturbance prohibits changes in the environment and suppresses species establishment. The effects of this continued disturbance are seen in the tropical forests in national parks in Uganda and Tanzania in Eastern Africa with African elephants (Loxodonta africana). The continuous browsing on trees by the ...
