Is Quercus Virgiliana A Distinct Morphological And Genetic Entity Among European White Oaks?, Cristian Mihai Enescu, Alexandru Lucian Curtu, Neculae Şofletea

Turkish Journal of Agriculture and Forestry

The existence of Quercus virgiliana Ten. is a subject of debate among botanists and silviculturists. It was considered a distinct species, sometimes as an intraspecific taxonomic unit of Q. pubescens L., or was not even recognized as a taxon or infrataxon. This disagreement with regard to the taxonomic classification is explained by the morphological similarities between Q. virgiliana and Q. pubescens, with a small overlap between particular leaf and fruit traits. The main objective of this study was to evaluate the macromorphological fruit and leaf descriptors in Romanian populations of pubescent oaks. We wanted to find which traits discriminate between …

Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard

Journal of the Arkansas Academy of Science

Spring-fed streams are abundant in karst topographic regions such as the Ozarks, providing an important and valuable water resource. Many of these spring-fed streams presently receive agriculture runoff, but few studies have examined the impacts of this runoff on water quality. We examined water quality in Ozark spring-fed streams surrounded by either agricultural (N=3) or primarily forested land (N=3) in the riparian zone. We hypothesized that agricultural sites would have greater dissolved nutrient concentrations and conductivity than forested sites and that water quality would fluctuate with distance from the spring source. Conductivity (p

Comparing Aboveground Biomass Predictions For An Uneven-Aged Pine-Dominated Stand Using Local, Regional, And National Models, Don C. Bragg, K. M. Mcelligott Jan 2013

Comparing Aboveground Biomass Predictions For An Uneven-Aged Pine-Dominated Stand Using Local, Regional, And National Models, Don C. Bragg, K. M. Mcelligott

Journal of the Arkansas Academy of Science

Sequestration by Arkansas forests removes carbon dioxide from the atmosphere, storing this carbon in biomass that fills a number of critical ecological and socioeconomic functions. We need a better understanding of the contribution of forests to the carbon cycle, including the accurate quantification of tree biomass. Models have long been developed to predict aboveground live tree biomass, but few of these have been derived from Arkansas forests. Since there is geographic variability in the growth and yield of pine as a function of genetics, site conditions, growth rate, stand stocking, and other factors, we decided to compare aboveground tree biomass …

Effect Of Geographical Variation On The Sugar Composition Of The Oriental Beech (Fagus Orientalis Lipsky), Deni̇z Güney, Zehra Duygu Bak, Fatma Aydinoğlu, İbrahi̇m Turna, Fai̇k Ahmet Ayaz

Turkish Journal of Agriculture and Forestry

Geographical variation in soluble sugar concentrations in seeds from oriental beech (Fagus orientalis Lipsky) trees of different origins in Turkey was determined using high performance liquid chromatography. The results demonstrated that the most significant soluble sugars, in order of importance, were sucrose, glucose, and fructose. All free sugars varied significantly (P < 0.05) within and among populations. In general, both total and soluble sugar levels tended to be higher in northern populations compared to southern ones. Cluster and discriminant analyses divided seed sources into 3 distinct groups corresponding to a north, south, and west division of oriental beech populations.

Intercepted Rainfall In Abies Fabri Forest With Different-Aged Stands In Southwestern China, Xiangyang Sun, Genxu Wang, Yun Lin, Linan Liu, Yang Gao

Turkish Journal of Agriculture and Forestry

Interception is one of the most important hydrological processes. Most investigations merely focus on canopy interception, but forest floor interception should also be considered. The stand age also influences interception. To explore the interception characteristics of Abies fabri with different stand ages, canopy, stem, and forest floor, interceptions were evaluated during the rainy season of 2009 (from May to October 2009). The total interception rates were found to be 28.8%, 25.5%, and 31.3% for young, middle-aged, and mature forest stands, respectively. Forest floor interception accounted for 19.1%, 18.1%, and 10.0% of the total interception, respectively. We concluded that the differences …

Geography

We compare conservation outcomes between a protected area (PA) and four indigenous common-property regimes (CPRs) under differing degrees of market integration in the Ecuadorian Amazon. We first assess how market forces and common-pool resource institutions governing processes of forest conversion affect biodiversity and forest cover, and whether institutions mitigate the effect of market forces. We then analyze how biodiversity and forest cover differ between a PA, and communities with different market access. Finally, we link biodiversity and forest cover changes within communities to differences in land-use practices. While we show similar levels of forest cover and biodiversity between the PA …

The Role Of Ectomycorrhizal Fungi On Fertilized And Unfertilized Nursery Grown White Spruce, Alistair James Henry Smith Ii

Dissertations, Master's Theses and Master's Reports - Open

Nursery grown seedlings are an essential part of the forestry industry. These seedlings are grown under high nutrient conditions caused by fertilization. Though grown in a controlled environment, symbionts such as ectomycorrhizal fungi (EcMF) are often found in these conditions. To examine the effects of EcMF in these conditions, colonized Picea glauca seedlings were collected from Toumey Nursery in Watersmeet, MI. After collection, the EcMF present were morphotyped, and seedlings with different morphotypes were divided equally into two treatment types- fertilized and unfertilized. Seedlings received treatment for one growing season. After that time, seedlings were collected, ectomycorrhizas identified using morphotyping …

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. …
