Turkish Journal of Agriculture and Forestry
In this study, 4-sided rectangular full-size cabinets from 2 types of medium-density fiberboard (MDF; melamine-coated MDF with edge band and uncoated MDF without edge band) were manufactured and tested. Screws with nominal size of 4 × 40 mm were used for joint fabrication. Cabinets were kept in a conditioned climate chamber for accelerated aging treatment and their maximum load-bearing capacity was measured. Results revealed that approximately one-third of the load-carrying capacity of both types of cabinets (when compared to control samples) was lost after aging cycles. The ultimate strength of cabinets (in both control samples and after aging cycles) constructed …
Grain Yield Production Of Sudan Grass (Sorghum Sudanense (Piper) Stapf) As Influenced By Cutting Numbers, Potassium Rates, And Intrarow Spacing In A Semiarid Environment, Ahmed Awad, Salah Hafiz, Mohammed Sabry Hammada, Azza El-Nouby, Salah El-Hendawy

Threshold Responses Of Forest Birds To Landscape Changes Around Exurban Development, Todd R. Lookingbill, Marcela Suarez-Rubio, Scott Wilson, Peter Leimgruber
Geography and the Environment Faculty Publications
Low-density residential development (i.e., exurban development) is often embedded within a matrix of protected areas and natural amenities, raising concern about its ecological consequences. Forest-dependent species are particularly susceptible to human settlement even at low housing densities typical of exurban areas. However, few studies have examined the response of forest birds to this increasingly common form of land conversion. The aim of this study was to assess whether, how, and at what scale forest birds respond to changes in habitat due to exurban growth. We evaluated changes in habitat composition (amount) and configuration (arrangement) for forest and forest-edge species around …

A Predictive Model For Soil Seed Bank Outcomes In The Pyrenophora Semeniperda-Bromus Tectorum Pathosystem, Phil Stewart Allen, Susan E. Meyer, Julie Beckstead
Biology Faculty Scholarship
Pyrenophora semeniperda is abundant in soil seed banks of Bromus tectorum, where it kills a fraction of seeds throughout the year. The pathogen engages in a race with host seeds for endosperm resources; the pathogen success is negatively correlated with seed germination speed. We developed a deterministic model to predict pathosystem outcomes (seed death versus seed escape), using seed bank data from 80 sites collected over a 13-year period. The response variable (killed seeds in the spring seed bank) was regressed on multiple predictor variables (pathogen and host densities at seed dispersal, amount and timing of precipitation). Increased mortality …

Turkish Journal of Agriculture and Forestry
In order to lower bleaching costs, various prebleaching methods have been investigated. In the current work 3 prebleaching methods, peroxyformic acid, oxygen, and xylanase, were investigated in bamboo and hardwood kraft pulp produced by Kharnaphuli Paper Mills. Among these 3 methods, peroxyformic acid showed the most promising results. Peroxyformic acid prebleaching reduced kappa numbers by 38% and 30% and increased brightness by 12.2% and 8.6% in hardwood and bamboo pulp, respectively. Using 30 kg ClO_2 t^{-1} of pulp, hardwood pulp attained 77.2% brightness, while peroxyformic-acid-prebleached pulp attained 86% brightness without a reduction in viscosity in D_0E_pD_1 bleaching sequences.

Decision Making In Forest Road Planning Considering Both Skidding And Road Costs: A Case Study In The Hyrcanian Forest In Iran, M. Jourgholami, E. Abdi, Woodam Chung
Forest Management Faculty Publications
Hyrcanian forest is the only forest designated for commercial timber production in Iran. Ground-based skidding is the most common extraction system used in the forest, though large parts of the forest are still inaccessible due to the low road density (1-2 m ha-1). To facilitate timber harvesting in the forest, it has been proposed to increase the road density up to 20 m ha-1. The aim of this study was to incorporate the estimated skidding costs through a time study into an existing transportation planning tool, NETWORK 2000, to help decision making on forest road building. …

Latent Resilience In Ponderosa Pine Forest: Effects Of Resumed Frequent Fire, Andrew J. Larson, R. Travis Belote, C. Alina Cansler, Sean A. Parks, Matthew S. Dietz
Forest Management Faculty Publications
Ecological systems often exhibit resilient states that are maintained through negative feedbacks. In ponderosa pine forests, fire historically represented the negative feedback mechanism that maintained ecosystem resilience; fire exclusion reduced that resilience, predisposing the transition to an alternative ecosystem state upon reintroduction of fire. We evaluated the effects of reintroduced frequent wildfire in unlogged, fire-excluded, ponderosa pine forest in the Bob Marshall Wilderness, Montana, USA. Initial reintroduction of fire in 2003 reduced tree density and consumed surface fuels, but also stimulated establishment of a dense cohort of lodgepole pine, maintaining a trajectory toward an alternative state. Resumption of a frequent …

Agroforestry And Smallholder Farmers: Climate Change Adaptation Through Sustainable Land Use, Colin Mccabe
Capstone Collection
Agriculture in the developing world will be extremely hard hit by climate change, and smallholder farmers in Least Developed Countries (LDCs) are among the most vulnerable to its impacts. There is a range of agricultural adaptations to climate change, and each context demands a unique appraisal of impacts and adaptations based on specific geography, local climate variability and expected change, and social conditions. The term “climate-smart agriculture” (CSA) has come to embody a set of practices in crop and livestock cultivation that 1) reduce greenhouse gas emissions (climate change mitigation), 2) build resilience to the impacts of climate change for …

Effects Of Streamside Management Zone Timber Harvest On Salamander Communities In Robinson Forest, Thomas Maigret
Theses and Dissertations--Forestry and Natural Resources
Salamanders are critical components of forest ecosystems, in terms of total biomass, as well as for their value as indicators of ecosystem stress. Considering the worldwide decline in amphibian populations, the known effects of timber harvest on salamander populations, and the importance of the forest products industry in Kentucky and elsewhere, the impacts of silvicultural operations on salamander communities cannot be overlooked. The objective was to investigate the effects of three different silvicultural treatments, each involving different streamside management zone (SMZ) characteristics, on salamander communities in ephemeral streams. Data were collected by regular checks of pitfall traps, coverboards, and transect …

Forest Harvest Equipment Movement And Sediment Delivery To Streams, Daniel Whiteside Bowker
Theses and Dissertations--Forestry and Natural Resources
Streamside management zones (SMZs) have become important management techniques to prevent the introduction of sediment to stream networks. This study examined the current Kentucky best management practice (BMP) guidelines for SMZs by outfitting mobile forest harvest equipment with global positioning system (GPS) receivers, enabling modeling of equipment traffic and spatial analysis of stream sediment delivery. Three SMZ configurations were implemented during commercial timber harvest, along with four different techniques of crossing ephemeral channels, in order to determine where and why sediment was introduced to the stream network. Results indicate that increasing the SMZ buffer width leads to decreased sediment delivery, …
