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 …
Habitat Utilization Of Fish Species On The Ohio River: Preliminary Development Of A Multi-Metric Habitat Index, James P. Hawkes
Habitat Utilization Of Fish Species On The Ohio River: Preliminary Development Of A Multi-Metric Habitat Index, James P. Hawkes
Theses, Dissertations and Capstones
Development of a habitat index requires an understanding of the longitudinal distribution of habitat, fish assemblages, and how the two interact. Because of the complexity and size of the Ohio River, this understanding has not been reached. Habitat analysis has long been considered, and is essential, in assigning impaired and reference condition of habitat quality. The Ohio River is diverse in the distribution of its habitat within pool and river-wide. An Analysis of Variance (ANOVA) was used to analyze these distributions. Within pool assessment of % habitat composition revealed woody cover and vegetation types were significantly greater in the lowest …
The Life History Of The Cave Salamander, Eurycea Lucifuga Rafinesque, In West Virginia, Andrew James Longenecker
The Life History Of The Cave Salamander, Eurycea Lucifuga Rafinesque, In West Virginia, Andrew James Longenecker
Theses, Dissertations and Capstones
In West Virginia, as throughout its range, there is limited information about the life history of the cave salamander (Eurycea lucifuga). The purpose of this study was to describe the natural history of this species in West Virginia. The objectives of this study were to determine habitat selection of the cave salamander, to ascertain its environmental characteristics, and to study its reproductive and non-reproductive biology. Three study caves were located in Greenbrier County, West Virginia. All sites were examined at least once each month from May 1999 through April 2000. Caves were divided into three zones: entrance, twilight, …
Ecology And Sympatric Relations Of Crevice Salamanders In Randolph County, West Virginia, Jayme Linn Waldron
Ecology And Sympatric Relations Of Crevice Salamanders In Randolph County, West Virginia, Jayme Linn Waldron
Theses, Dissertations and Capstones
By implementing a mark-recapture study, I investigated the ecology of three species of sympatric plethodontid salamanders (Aneides aeneus, Desmognathus ochrophaeus, and Plethodon glutinosus) on rock outcrops in the Westvaco Wildlife and Ecosystem Research Forest, Randolph County, West Virginia. By examining activity patterns, vertical stratification, and habitat preference for A. aeneus, D. ochrophaeus, and P. glutinosus, I attempted to offer some insight into how these sympatric species avoid competition on small, isolated rock outcrops. Twenty-one surveys, both nocturnal and diurnal, were performed between 11 May and 17 October, 1999. During this time, 89 salamanders, encompassing five species ( …
Changes Among Ohio River Fish Populations Due To Water Quality Improvements And High-Lift Dams, Benjamin Lowman
Changes Among Ohio River Fish Populations Due To Water Quality Improvements And High-Lift Dams, Benjamin Lowman
Theses, Dissertations and Capstones
Fish populations in the Ohio River have been monitored extensively by the Ohio River Valley Water Sanitation Commission (ORSANCO), along with state and Federal agencies, for over 40 years. The population data, collected via lock chamber rotenone surveys, showed that many species of Ohio River fish have demonstrated marked increases in abundance since these studies began. These trends in population density, both gradual and sharp, are likely associated with water quality improvements and the construction of high-lift dams. Pearson-r correlation through linear regression analyses showed 23 species or 42% of populations examined exhibit significant density increases from 1957 to 1998. …
