Dopamine Modulates The Lateral Giant Neuron And Serotonergic Facilitation In Crayfish, Joshua Scott Titlow
Dopamine Modulates The Lateral Giant Neuron And Serotonergic Facilitation In Crayfish, Joshua Scott Titlow
Theses, Dissertations and Capstones
The lateral giant (LG) neural circuit is a model system used to study the function of individual neurons. The LG circuit is part of a tail flip escape reflex that is a defensive behavior for crayfish. This thesis begins by addressing the effects of dopamine (DA), a neurotransmitter involved in normal and abnormal behaviors of most animals. Here it is shown that dopamine decreases the excitability of the LG neuron, a trigger for the escape reflex. An electrophysiology protocol was used to mimic sensory input to the LG neuron. Stimulating a sensory nerve in the last ganglion with an electrode …
Movement Patterns And Artificial Arboreal Cover Use Of Green Salamanders (Aneides Aeneus) In Kanawha County, West Virginia, Sarah Elizabeth Miloski
Movement Patterns And Artificial Arboreal Cover Use Of Green Salamanders (Aneides Aeneus) In Kanawha County, West Virginia, Sarah Elizabeth Miloski
Theses, Dissertations and Capstones
Global amphibian declines have spawned a need for amphibian monitoring studies using standardized sampling techniques for early detection of population declines. The Green Salamander (Aneides aeneus) is a declining plethodontid salamander (Family: Plethodontidae) associated with rock outcrops and arboreal habitat. The unique habitat requirements of this species make A. aeneus populations particularly susceptible to habitat perturbations. Although primarily associated with rock outcrops, A. aeneus morphology and ecology suggest that A. aeneus may be highly mobile. High mobility has important implications for habitat management, particularly pertaining to land surrounding rock outcrops. However, few studies have addressed plethodontid movement patterns, which are …
The Natural History & Distribution Of Riverine Turtles In West Virginia, Linh Diem Phu
The Natural History & Distribution Of Riverine Turtles In West Virginia, Linh Diem Phu
Theses, Dissertations and Capstones
Turtles are unique evolutionary marvels that evolved from amphibians and developed their protective shelled form more than 200 million years ago. In West Virginia, there are 10 native species of turtles, 9 of which are aquatic. Most of these aquatic turtles feed on carrion and dead plant matter, in the water and essentially "clean" our water systems. Turtles are long-lived animals with sensitive life stages that can serve as both long-term and short-term bioindicators of environmental health. With the increase in commercial trade, habitat fragmentation, degradation, destruction, there has been a marked decline in turtle species. The need for well …
A Natural History Study Of Bufo A. Americanus, The Eastern American Toad, And The Phenology Of Spring Breeders In Southwest West Virginia, Tomi Maria Bergstrom
A Natural History Study Of Bufo A. Americanus, The Eastern American Toad, And The Phenology Of Spring Breeders In Southwest West Virginia, Tomi Maria Bergstrom
Theses, Dissertations and Capstones
Natural history traits have not been thoroughly collected and analyzed on the "common hoptoad," Bufo a. americanus (eastern American toad) in West Virginia. Updating natural history information is important to understand the present population status (Jackson, 2001). I chose to have two study sites at opposing physiographic regions to constitute a better understanding of B. a. americanus natural history in WV. The study was initiated in spring 2008 at Beech Fork State Park and Green Bottom Swamp Wildlife Refuge (in Mason and Cabell counties) and in 2009 incorporated Canaan Valley of Tucker County. Ten natural history morphometrics and characters were …
Testing The Behavioral Responses Of West Virginia Turtles To Roads And Vehicles, Aaron Clinton Gooley
Testing The Behavioral Responses Of West Virginia Turtles To Roads And Vehicles, Aaron Clinton Gooley
Theses, Dissertations and Capstones
Road mortality has been identified as a major threat to many turtle species; however, response to passing vehicles, crossing speed, and general behavior while crossing roads has never been investigated in turtles. To investigate these factors, Midland Painted Turtles (Chrysemys picta marginata), Eastern Box Turtles (Terrapene c. carolina), and Stinkpots (Sternotherus odoratus) were collected and placed in a release box on the side of a closed road with an active road running parallel to it 26 m away. Turtles were released via a pulley-operated door facing the road, and their actions videotaped by an …
Long-Term Growth And Monitoring Of The Eastern Hellbender (Cryptobranchus A. Alleganiensis) In Eastern West Virginia, Douglas Charles Horchler
Long-Term Growth And Monitoring Of The Eastern Hellbender (Cryptobranchus A. Alleganiensis) In Eastern West Virginia, Douglas Charles Horchler
Theses, Dissertations and Capstones
Amphibian declines have been well documented, specifically in the last few decades. The Hellbender, Cryptobranchus alleganiensis, one of North America’s largest salamander species, has suffered dramatic declines throughout much of its range, with estimated declines of up to 77 percent recently documented in some populations. With diurnal and nocturnal searches and mark-recapture techniques, I collected data on the status of Eastern Hellbender populations in Eastern West Virginia. We re-sampled a study site on the West Fork of the Greenbrier River that was first examined in 1998 by Jeff Humphries. Long-term growth and survivorship data were collected and compared to 1998 …
