Herpetological Assemblages In Tropical Dry Forests Of The Azuero Peninsula, Panama: An Evaluation Of Reforestation, Tyler Kovacs

Masters Theses, 2010-2019

Tropical dry forests are considered one of the most endangered tropical ecosystems making reforestation increasingly necessary to restore Panama’s unique ecoregion. The isolated dry ecoregion surrounding the Bay of Parita in Panama has a long history of deforestation and cattle grazing. Successful reforestation of this land is important to restore ecosystem health and biodiversity. In Panama, reforestation ranges from monocultures of exotic teak (Tectona grandis) to passive regeneration. Faunal recovery within these reforestation systems may vary due to different habitat characteristics. In this study, amphibian and reptile communities were compared in two types of reforestation systems and protected riparian forests …

Losses Of Mineral Soil Carbon Largely Offset Biomass Accumulation Fifteen Years After Whole-Tree Harvest In A Northern Hardwood Forest, Matthew A. Vadeboncoeur, Steven P. Hamburg, Chris E. Johnson, Jonathan Sanderman

All Materials

Changes in soil carbon stocks following forest harvest can be an important component of ecosystem and landscape-scale C budgets in systems managed for bioenergy or carbon-trading markets. However, these changes are characterized less often and with less certainty than easier-to-measure aboveground stocks. We sampled soils prior to the whole-tree harvest of Watershed 5 at the Hubbard Brook Experimental Forest in 1983, and again in years 3, 8, and 15 following harvest. The repeated measures of total soil C in this stand show no net change in the O horizon over 15 years, though mixing with the mineral soil reduced observed …

Using The Forestry Reclamation Approach For Reclaimed Surface Mineland In The Western Gulf: Effects On Pinus Taeda Seedling Growth And Survival, Cassie Phillips, Jeremy Stovall, Hans Williams, Kenneth Farrish

Electronic Theses and Dissertations

While land reclamation efforts of surface mines have considerably increased soil stability since the implementation of SMCRA (Surface Mining Control and Reclamation Act), research suggests that resulting soil compaction hinders the productivity of forests post-mining. The Forestry Reclamation Approach (FRA) was developed to improve forest health in the Appalachian region through a five-step process that minimizes soil compaction and establishes a productive forest. The FRA has not yet been tested in the western Gulf Coastal Plain (GCP). The higher clay content of some GCP soils and the dearth of coarse fragments (e.g. cobbles, stones and boulders) may affect reclamation practices …

Effects Of Experimental Forest Management On Avian Communities In The Missouri Ozarks, David R. Hollie

Electronic Theses & Dissertations

In recent decades, concern for migratory birds has stimulated research assessing the relationships between forest management and bird populations. The Missouri Ozark Forest Ecosystem Project (MOFEP) is a long-term, landscape-scale experiment designed to examine the effects of even-aged (i.e. clearcutting), uneven-aged (i.e. selection cutting), and no harvest forest management on ecosystem level processes. The management systems were randomly assigned to three sites each (mean area = 400 ha) under a 100-year rotation with a 15-year re-entry period.

In the first chapter, we used non-metric multidimensional scaling and generalized linear mixed models to investigate the effects of silvicultural treatment and year-since-harvest …

Analysis And Conservation Of Native Forests At Kessler Mountain Fayetteville, Arkansas, Alan James Edmondson

Graduate Theses and Dissertations

Kessler Mountain in Fayetteville Arkansas has long been recognized for its beauty and natural resources. Parts of Kessler Mountain have been homesteaded and developed in the past, but most of the mountain has remained relatively undisturbed. The planned development of over 4,000 housing units to cover Kessler Mountain stimulated controversy and consideration of other management alternatives. A twist of fate involving an economic recession, a dedicated group of outdoor recreation enthusiasts, and environmental conservationists led to the permanent protection of 384 acres in the Kessler Mountain Regional Park. To help evaluate the natural resources at Kessler Mountain, forest composition, structure, …

Daily To Seasonal Moisture Signals Present In Sub-Annual Tree-Ring Data, Ian Howard

Graduate Theses and Dissertations

In recent decades, there has been an increase in the development of sub-annual earlywood (EW) and latewood (LW) width tree-ring chronologies that have been used to make long-term inferences about discrete seasonal moisture variability for different regions of North America. This doctoral research developed a new network of EW, LW, and adjusted latewood (LWa) tree-ring chronologies from the western Great Plains. These chronologies were used to reconstruct 300+ years of spring and summer moisture variability over the northern and southern Plains. The reconstructions document new information about the long-term seasonal climate history of the Great Plains, including the unusual nature …

Habitat Characteristics And Selection By Ornate Box Turtles In The Sandhills Of South Dakota, Daniel W, Uresk, Alessandra Higa

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The ornate box turtle (Terrapene ornata Agassiz) is a species of greatest conservation need in South Dakota. Habitat loss through agricultural development and fragmentation is the main threat to the species throughout its range, which extends from Wisconsin and northern Indiana through the central Great Plains, and from southern South Dakota to Arizona, northern Mexico, and the Gulf Coast of Texas. The objectives of this study were to determine the ornate box turtle’s preferred vegetation characteristics (microhabitat) compared to the available habitat (macrohabitat) on the Pine Ridge Reservation, South Dakota Sandhills region, during 2010–2011. In both years, using a modified …

Assessment Of Soil Particle Size Distribution Under Four Land Covers In Nachusa Grasslands Of Northern Illinois, Reni Truhtcheva Owikoti, Diana Acosta, Markeia Scruggs, Xiaoyong Chen

Research Days

Soil particle composition is one of the main physical properties of soil that affects soil fertility and quality. The fractal dimension of soil particle size distribution (PSD) can be used to quantitatively evaluate the particle composition of soils. Land cover change with corresponding management practices is recognized as one important driving force affecting soil PSD alterations. The objective of this project was to determine the changes in soil PSD under four plant covers (Woodland, Wetland, Prairie, and Savannah) at the Nachusa Grasslands in North Illinois. The soil PSD was determined by their settling rates in an aqueous solution using hydrometer. …

It's Essential: The Ylang-Ylang Trade On Nosy Be, James Sleigh

Independent Study Project (ISP) Collection

This paper attempts to describe the production and sale of Ylang-Ylang from cultivation of the tree to the export of the flower, and examines the roles and power that each stakeholder has in the value chain. From there, the paper will look at issues associated with the trade; namely of the threat to the terrestrial ecosystem and the profit imbalance in the industry. Finally, the paper turns to potential strategies to resolve the previously stated issues associated with the production and sale of Ylang-Ylang. As a whole I hope that the paper can be seen as a rough survey of …

Women In Conservation: A Study Of Effective Community-Based Conservation And The Empowerment Of Women In Tanzania, Ruby Krietzman

Independent Study Project (ISP) Collection

The subject of this study is women involved in Community-Based Conservation (CBC) from areas surrounding Lake Manyara National Park, Ngorongoro Conservation Area, and Mount Kilimanjaro National Park. CBC is a participatory process between people and organizations who have responsibilities affecting conservation. Communities surrounding protected conservation areas tend to experience high levels of poverty and marginalization due to exclusive conservation policies and the lack of co-management principles. Although tourism revenue is abundant in these locations, the benefits rarely impact local community members that disproportionately experience the effects of conservation. This is especially true for women who hold the responsibilities of collecting …

Scientists, Uncertainty And Nature, An Analysis Of The Development, Implementation And Unintended Consequences Of The Northwest Forest Plan, Gilbert David Miller

Dissertations and Theses

The conflict in the Pacific Northwest between competing visions of how federal forests should be managed resulted in a political stalemate in the early 1990s. The Northwest Forest Plan (NWFP) was initiated to resolve the demands for maintaining ecosystem processes and biological diversity with the social and economic needs for timber harvest. The foundation for the plan rested with the development of ecosystem management. The intent of this research is to explore the events which led up to the adoption of the NWFP, how it was implemented by the US Forest Service and Bureau of Land Management and the subsequent …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Earth System Models (ESMs) are essential tools for understanding and predicting global change, but they cannot explicitly resolve hillslope‐scale terrain structures that fundamentally organize water, energy, and biogeochemical stores and fluxes at subgrid scales. Here we bring together hydrologists, Critical Zone scientists, and ESM developers, to explore how hillslope structures may modulate ESM grid‐level water, energy, and biogeochemical fluxes. In contrast to the one‐dimensional (1‐D), 2‐ to 3‐mdeep, and free‐draining soil hydrology in most ESM land models, we hypothesize that 3‐D, lateral ridge‐to‐valley flow through shallow and deep paths and insolation contrasts between sunny and shady slopes are the top …
