Characterizing The Vegetation And Effects Of Climate Change On Parris Island, A Sea Island Ecosystem, Cody Hart Goodson
Characterizing The Vegetation And Effects Of Climate Change On Parris Island, A Sea Island Ecosystem, Cody Hart Goodson
Theses, Dissertations and Capstones
Coastal habitats provide many ecosystem services, protecting coastlines from storm surges and erosion, diminishing the effects of eutrophication, sequestering large amounts of carbon, and acting as vital wildlife habitat. Sea-level rise and increased storm surge intensity associated with climate change are increasingly disrupting coastal habitats. These disturbances can shift environmental gradients that drive the zonation of coastal vegetation types, driving habitat conversion. Monitoring coastal habitat conversion can improve our understanding of the dynamic effects of climate change on these landscapes. Therefore, our objectives for chapter 1 were to identify and describe the distributions of vegetation types present on Marine Corps …
Assessing Grazing Impacts On A Tropical Dry Forest System In Madagascar Through Vegetation, Satellite Image, Lemur Occupancy, And Acoustic Analysis, Lyndsay Lee Rankin
Assessing Grazing Impacts On A Tropical Dry Forest System In Madagascar Through Vegetation, Satellite Image, Lemur Occupancy, And Acoustic Analysis, Lyndsay Lee Rankin
Theses, Dissertations and Capstones
The ability to assess the quality or ecological value of a landscape is a useful tool in effective conservation and natural resource management. Ecosystem biodiversity and functionality are reduced when human activities cause habitat alteration and/or fragmentation. Compromised habitats are unlikely to support naturally occurring communities or healthy ecosystem functions. Conservation scientists have historically concentrated their efforts on large, intact habitats with little human disturbance; the conservation value of small and/or disturbed areas has been comparatively overlooked. One limitation may be a lack of tools to identify disturbed areas with conservation value. Techniques that allow researchers to assess the habitat …
Terrestrial Habitat Use Of Marbled Salamanders Ambystoma Opacum: A Site Specific Approach, Frank Piccininni
Terrestrial Habitat Use Of Marbled Salamanders Ambystoma Opacum: A Site Specific Approach, Frank Piccininni
Theses, Dissertations and Capstones
Habitat destruction, fragmentation and degradation have contributed heavily to the decline of amphibian populations such as Marbled Salamanders (Ambystoma opacum). Often, ambystomatid water resources are conserved without consideration for the equally important terrestrial habitat. This is partly due to a lack of information regarding the relationship between ecological succession, plant community composition, microhabitat and salamander abundance. Three sampling transects consisting of drift fence arrays, vegetation assessments and microhabitat surveys were extended 100 m into the terrestrial habitat surrounding a seasonal wetland at Beech Fork State Park in Wayne County, West Virginia. Principal components analysis was used to identify …
A Taxonomic Study Of The Genus Acris And The Status Of Acris Crepitans Blanchardi (Harper), Blanchard's Cricket Frog, In Southern Ohio And Western West Virginia, Amy M. Hamilton
Theses, Dissertations and Capstones
Distributions of Acris crepitans and Acris gryllus cover most of the eastern United States with some overlap, and the subspecies Acris crepitans blanchardi and Acris crepitans crepitans also occur sympathric in parts of their ranges. My study analyzed 15 morphological characteristics of A. c. blanchardi, A. c. crepitans, and A. g. gryllus using Canonical Discriminate Analysis. Results support current taxonomy, showing the most separation between A. crepitans and A. gryllus and some overlap between A. c. blanchardi and A. c. crepitans. Sexual dimorphism was seen only in A. c. blanchardi and A. c. crepitans with females being larger …
An Analysis Of Vegetation And Environmental Parameters At Mitigated Wetland Sites Located In The Upper Scioto River Drainage Basin, Central Ohio, Desiree L. Lawson
An Analysis Of Vegetation And Environmental Parameters At Mitigated Wetland Sites Located In The Upper Scioto River Drainage Basin, Central Ohio, Desiree L. Lawson
Theses, Dissertations and Capstones
The construction of wetland mitigation sites to compensate for authorized losses is necessary under Section 404 of the Clean Water Act. Many mitigation sites have been determined to be unsuccessful. Monitoring of sites is necessary to determine if functions of natural wetlands have been replaced. Six mitigation sites in the Upper Scioto River watershed in central Ohio were chosen for study. Representative transects were established beginning in uplands adjacent to the wetlands (old field, OF), running through areas characterized by seasonal inundation (seasonally pooled, SP) and ending in permanent pools of inundation characterized by little or no vegetation (permanent pooled …
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Theses, Dissertations and Capstones
Soil processes often exhibit spatial heterogeneity within ecosystems and this heterogeneity may influence community structure. This study was conducted to determine spatial patterns and variability of soil nutrients and plant communities within different vegetation types in a stream floodplain in southwestern West Virginia. One 5-m × 5-m site was established in each of three vegetation/drainage types: pasture (PA), old field (OF), and wetland scar (SC). Pasture and SC sites were located ~25 m apart on flat bottomland; the OF site was located on a moderate slope 6.3 m above bottomland, ~200 m from PA and SC. A 10-m × 1-m …
Computer Simulation For Feature Extraction In Pattern Recognition And Geobiophysical Modeling In Mountaineous Wetland Delineation, Natalie Ripsher
Computer Simulation For Feature Extraction In Pattern Recognition And Geobiophysical Modeling In Mountaineous Wetland Delineation, Natalie Ripsher
Theses, Dissertations and Capstones
Delineation of wetlands is an important aspect of protecting of these ecologically diverse and biocomplex habitats. Selected image-processing techniques are applied to remotely sensed imagery of Canaan Valley, in order to determine the best method of extracting wetland features for habitat delineation. Remotely sensed data from April 1997 and September 1999 were compared to determine the accuracy of feature extraction, and the effect of seasonal and long term climate change on wetland delineation. Pattern recognition for feature extraction was used to identify vegetation associations and changes in habitats. Computer simulation of the infrared band was performed using ER Mapper so …
The Bog Forest Community At Cranberry Glades, West Virginia, Amy Casdorph Kokesh
The Bog Forest Community At Cranberry Glades, West Virginia, Amy Casdorph Kokesh
Theses, Dissertations and Capstones
An investigation of the Bog Forest Community of the Cranberry Glades Botanical Area and Cranberry Wilderness/ Monongahela National Forest, West Virginia, revealed a dominance of mixed conifers and northern hardwoods. The composition of the forest was determined through vegetational analysis of the forest strata using the list-count quadrat method. Tsuqa canadensis, Betula alleqhaniensis, Prunus serotina, and Picea rubens were dominant while eight additional species in the arboreal stratum were found to be tolerant subordinates. Rhododendron maximum dominated the understory/shrub stratum forming thickets along the interior boundary of the bog forest. The herbaceous stratum was characterized by species generally affiliated with …
