Diversity Of Ectomycorrhizal Fungi On Two Reclaimed Surface Mines Differing In Soil Properties, Betsy S. Kurnik
Diversity Of Ectomycorrhizal Fungi On Two Reclaimed Surface Mines Differing In Soil Properties, Betsy S. Kurnik
Graduate Theses, Dissertations, and Problem Reports
I analyzed community structure of ectomycorrhizal fungi on white pine (Pinus strobus) on two reclaimed surface mines in eastern Ohio. One site was acidic and metal-stressed, the other was alkaline. Completely different community composition was found on the two sites by PCR/ITS/RFLP analyses of field collected mycorrhizae. However, Shannon-Wiener index values indicated that the two communities were equally diverse. A population of isolates of one species common to both sites was obtained from trap cultures planted with white pine. The identity of this species as Wilcoxina mikolae was established through DNA sequencing of the ITS region. The W. mikolae populations …
Evaluation Of The Use Of Remotely Sensed Images To Speciate Mixed Appalachian Forests, Doru Ioan Pacurari
Evaluation Of The Use Of Remotely Sensed Images To Speciate Mixed Appalachian Forests, Doru Ioan Pacurari
Graduate Theses, Dissertations, and Problem Reports
Advancements in technology have led to development of various new sensors and platforms. Among them, the airborne digital camera has potential for use in detailed forest vegetation management, and they offer a number of advantages over conventional aerial photographs. The aim of the study was to determine the ability to speciate mixed Appalachian hardwood forests using the Airborne Data Acquisition and Registration (ADAR) System 1000, and to determine the optimal spatial resolution and the optimal scale of the acquired images. Digital images of a 200-ha area in west central West Virginia were acquired for the study.;The first objective of the …
Assessing West Virginia Nipf Owner Characteristics And Preferred Assistance Topics, Daniel Joseph Magill
Assessing West Virginia Nipf Owner Characteristics And Preferred Assistance Topics, Daniel Joseph Magill
Graduate Theses, Dissertations, and Problem Reports
Four hundred and fifty-one Non-Industrial-Private-Forest (NIPF) owners (49% response rate) in West Virginia responded to a survey of their forestry assistance needs. Most of the socioeconomic characteristics of the respondents, their reasons for owning the property, the types of activities they were engaged in on the property and the agencies that provided assistance by themselves significantly (Chi2 & ANOVA) differentiated those interested and not interested in obtaining assistance. However, when all 39 factors were considered together (Logistic Regression) only a small number of these factors were needed to explain the difference between landowners wanting and not wanting a specific assistance …
Conservation And Management Of The Allegheny Woodrat In The Central Appalachians, Steven Bryan Castleberry
Conservation And Management Of The Allegheny Woodrat In The Central Appalachians, Steven Bryan Castleberry
Graduate Theses, Dissertations, and Problem Reports
The Allegheny woodrat occurs throughout the Appalachian Mountains, where it forms isolated colonies in rock outcrops, cliffs, and caves. Populations along the northern and western peripheries of the range have experienced drastic declines in the past 20--30 years. A paucity of ecological information is available for this species, particularly regarding the effects of anthropogenic disturbance. Furthermore, no information is available on population structure, gene flow, or relatedness among colonies. The objectives of my study were to examine the impacts of forest management practices on movements, home range, and habitat use and to determine genetic structure and levels of gene flow …
Factors Influencing Ruffed Grouse Productivity And Chick Survival In West Virginia, Christopher A. Dobony
Factors Influencing Ruffed Grouse Productivity And Chick Survival In West Virginia, Christopher A. Dobony
Graduate Theses, Dissertations, and Problem Reports
I examined productivity, chick mortality, and factors influencing ruffed grouse (Bonasa umbellus) chick survival in West Virginia during 1998--1999. The proportion of hens that attempted to nest, hen success, average clutch size, and hatch dates were similar between age classes, between sites, and between years. Hatch dates were similar between age classes and between sites. Depredation was the major cause of nest failure. I examined 2 types of radio transmitter attachment methods (glue-on and collar type) to determine mortality and survival in ≤3-day-old grouse chicks. Glue-on transmitters performed poorly, whereas collar types had excellent retention time. Chick survival was low …
Predicting Habitat Suitability For American Woodcock And Landscape-Level Assessment Of Habitat In West Virginia, Ann Klein Steketee
Predicting Habitat Suitability For American Woodcock And Landscape-Level Assessment Of Habitat In West Virginia, Ann Klein Steketee
Graduate Theses, Dissertations, and Problem Reports
The objectives of this study were to (1) develop models to predict potential habitat suitability for woodcock over large geographic areas in West Virginia (Chapter 4), (2) quantify and describe the local and landscape structural components and spatial patterns of woodcock habitat in the state (Chapter 3), and (3) to determine the current suitability and fate of woodcock habitat that was available in the mid-1970's (Chapter 5).;Differences between 165 woodcock flush points and 165 randomly generated points for proportion of 12 land-cover types and 4 metrics describing landscape composition and pattern were compared within 3 elevation groups and 8 spatial …
Food Habits Of The Allegheny Woodrat (Neotoma Magister ), Nikole Lee Castleberry
Food Habits Of The Allegheny Woodrat (Neotoma Magister ), Nikole Lee Castleberry
Graduate Theses, Dissertations, and Problem Reports
Regional declines in Allegheny woodrat (Neotoma magister ) populations suggest a better understanding of the ecology of this species is needed for proper management. I described seasonal food habits of the Allegheny woodrat in the Ridge and Valley and Allegheny Plateau physiographic provinces of West Virginia and Virginia using microhistological techniques. In the Allegheny Plateau, the top 5 food items were fungi, blueberries ( Vaccinium spp.), acorns (Quercus spp.), ferns ( Dryopteris spp.), and lichens. In the Ridge and Valley woodrats ate primarily blackberry (Rubus spp.) leaves, fungi, greenbrier (Smilax spp.) leaves, acorns, and oak leaves. Additionally, we examined the …
Effects Of Diameter-Limit And Two-Age Timber Harvesting On Songbird Populations On An Industrial Forest In Central West Virginia, Cathy Ann Weakland
Effects Of Diameter-Limit And Two-Age Timber Harvesting On Songbird Populations On An Industrial Forest In Central West Virginia, Cathy Ann Weakland
Graduate Theses, Dissertations, and Problem Reports
Many studies examining forest fragmentation effects on songbirds have been conducted in landscapes significantly altered by urbanization or agriculturalization rather than forested landscapes. There is some evidence that forest fragmentation due to timber harvesting has different effects on bird abundance than fragmentation from other land uses. It is unknown how songbirds respond to different forms of timber harvesting as fragmentation events. Also, it is unclear if microhabitat-level or landscape-level characteristics are more important predictors of breeding bird occurrence in the central Appalachians. The objectives of my study were to determine the short-term effects of diameter-limit and two-age timber harvesting on …
