Control Of Food Intake And Expression Of Hunger In The Northern Water Snake, Nerodia Sipedon (L.), Paul Timothy Andreadis

Doctoral Dissertations

Most of what is known about the control and expression of appetite comes from studies of laboratory rodents. Such animals, which take small, frequent meals, are located at one end of a spectrum of feeding frequencies. The theme of the present work was to explore appetite in an animal that takes relatively large meals at long intervals. I studied some of the factors that control food intake and influence the expression of hunger in Northern water snakes, Nerodia sipedon; Serpentes: Colubridae). Subjects were collected in streams in eastern Tennessee, especially the Little River in Blount County.

In order to …

A Population Genetics Study Of Southern Appalachian Brook Trout, Stanley Zane Guffey

Doctoral Dissertations

Observations of anglers and naturalists, and the findings of molecular genetics, indicate that native Southern Appalachian brook trout populations comprise a distinct lineage of Salvelinus fontinalis. In this century, the stream mileage inhabited by the region's only native salmonid has been reduced by 70-80%. Attempts to restore declining populations by stocking have eroded the genetic integrity of many remaining native populations through hybridization with hatchery strains. In this study I review the decline and current status of brook trout in the Southern Appalachians (Part I), document the genetic structure of populations in Great Smoky Mountains National Park (Part II), …

Sp277-F-Azalea Leaf And Flower Gall, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Leaf and flower galls are commonly found on many flowering woody hosts, most often on azalea and camellia. This disease occurs on plants in the Ericaceae or heath family, as well as on some species in the Empetraceae, Lauraceae, Symplocaceae and Theaceae families; including andromeda, arbutus, azalea, blueberry, camellia, huckleberry, Labrador tea, leatherleaf (Chamaedaphne calyculata), leucothoe, kalmia (mountain laurel) and rhododendron. Azalea leaf and flower gall, caused by the fungus Exobasidium vaccinii can occur on woody ornamentals growing outdoors in landscape plantings and in greenhouses. Disease is more common on plants growing in humid, sheltered areas with little …

Subjects: A stratified random sample was taken from 1300 members of the American Dietetic Association's Public Health Nutrition Practice Group and directors of the Didactic Programs in Dietetics (DPD) and Dietetic Internship (DI) Programs. A total of 604 subjects were selected and mailed …

The Ontogeny Of Red Wolf (Canis Rufus) Social Behavior: Implications For Sociality And Taxonomic Status, Tarren Kay Wagener

Masters Theses

Patterns of behavioral development in closely related North American Canis have been studied extensively. Developmental trends have been used to assess species-typical social organization and taxonomic relationships i wolves (C. lupus), coyotes (C. latrans) and domestic dogs (C. familiaris). Despite its species designation, the taxonomic status of the closely related red wolf (C. rufus) is fiercely debated and a hybrid origin (C. lupus x C. latrans) has been proposed. The objective of the current study therefore was to analyze growth and behavioral development patterns in the red wolf and perform …

A Study Of Epixylic Bryophyte Ecology On Fraser Fir Logs In The Great Smoky Mountains National Park, Erica Choberka

Masters Theses

The Southern Appalachian spruce-fir forest is experiencing the chaotic conditions of ecosystem destruction resulting from the balsam woolly adelgid (Adelges piceae (Ratz)) infestation. In the present study, I have examined the community structure of bryophytes on fir logs in the high elevation spruce-fir forest of the Great Smoky Mountains National Park (GSMNP) to learn about the responses of bryophytes to the sudden change in forest structure.

This study has four primary objectives: 1) to provide an updated list of the epixylic bryophytes on fir logs in the spruce-fir forest of the GS MNP; 2) to compare results with previous …

Pb1610-Flowering Bulbs, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

A wealth of spring-, summer- and fallflowering bulbs can be used to extend the garden floral display from early spring until late fall. Some of these will be winter hardy and remain in the ground year-round. Others will not survive freezing temperatures and must be replanted each spring. Many are not even true bulbs, but are often sold along side true bulbs in mail order catalogs and at garden stores. The different types of underground storage structures that are frequently called bulbs include corms, tubers, tuberous roots, tuberous stems and rhizomes. These underground storage structures collectively are called “bulb-forms” or …

Sp341-T-Mud Daubers And Cicada Killers, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Mud daubers, mud wasps and cicada killers may become a nuisance when they nest around homes and other structures where people live, work and play. In spite of their formidable appearance, these solitary wasps are not aggressive and controls are rarely needed.

The Effects Of Cyclodextrin Mediated Lipid Depletion Of The Chloroplast Outer Envelope On The Import Of The Small Subunit Of Ribulose-1, 5-Bisphosphate Carboxylase/Oxygenase, Robert George Mynatt

Masters Theses

Chloroplasts have a genome that encodes a minority of proteins necessary for organelle function. The rest are encoded in the plant cell nucleus, translated in the cytosol, and post-translationally imported into the chloroplast. Nuclear encoded chloroplast precursor proteins are made as a precursor which contains an amino-terminal extension known as the transit peptide. Transit peptides are believed to be necessary and sufficient for proper targeting. Several studies have suggested that the initial chloroplast binding interaction is between the transit peptide and the lipids of the chloroplast outer chloroplast envelope. In this study, cyclodextrins are utilized to examine the role of …

Sp518 Gypsy Moth Management For Homeowners, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Soon, the gypsy moth will become a household word in Tennessee. This obnoxious new neighbor will be eating its way through our hardwood forests, leaving some forests bare.

The gypsy moth is an introduced exotic insect that defoliates hardwood trees, particularly oaks and hickories. Several successive defoliations by the gypsy moth may eventually kill the tree. The gypsy moth has the potential to decimate some older oak forests, similar to the effects of chestnut blight in the early 1900s. The moth was brought to Massachusetts from Europe in 1869 as part of a silk-making experiment. Some larvae escaped, and the …

Sp510 Diversified Urban Plantings, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

With a little creativity and a well-chosen repertoire of plant materials, there are ways to achieve picturesque and durable urban landscapes. Too often, a city planting consists of a row of the same evergreen trees throughout, or a virtual island of low shrubbery. Though plants for the city may need more careful selection, humdrum landscapes need not be the result.

Sp511 Plant The Right Tree In The Right Place, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Trees enhance the beauty and value of homes, streets and communities. However, trees planted in the wrong place can cause property damage and become a detriment rather than an asset. Planning the location and species of a tree will ensure that the tree will be an asset and not grow into a hazard or a nuisance.

“What tree should I plant?” is a question asked frequently by homeowners. The answer to the question depends on several factors:

1. Purpose for planting the tree.

2. Soil conditions.

3. Tree location, the right place.

4. Species growth and form, the right …

Sp512 Trees To Reconsider Before Planting, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

All trees have their good and bad characteristics. Rarely does a tree throughout its lifetime satisfy or even maintain the objectives for which it was planted. Trees become larger over time, often outgrowing their original growing space both above and below the ground. Some trees also droduct fruits or seeds that may be troublesome to the homeowner. An example of a tree planted to fulfill a need, but later presenting problems is silver maple, which grows and provides shade quickly. However, it is a short-lived tree with brittle wood prone to limb breakage during wind and ice storms. Another example …

Sp513 Small Flowering Trees For Tennessee Landscapes, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Small flowering trees are second only to shade trees for importance in the landscape. Flowering trees are valuable plants with colorful, showy blossoms and other unusual features that give interest and variety in the landscape. All trees flower, but large trees are valued for providing shade, even though flowers may be noticeable. Large trees establish the basic framework of the landscape and should be planted in key locations for optimal shading. Most properties need both small and large trees, which creates a more desirable landscape.

Carefully select your small flowering trees to ensure they fit into the landscape. In addition …

Sp515 Native Trees For Tennessee, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Native trees are a natural. They have been in Tennessee since before the arrival of European settlers. Native trees are already part of the ecosystem, contributing to local energy flows and nutrient cycles. Other organisms in the system are adapted to the structure, function and chemical composition of native trees. Birds, insects, fungi and other wildlife recognize and use native trees to support their biological needs. Trees introduced from other countries or areas, the so-called exotics, do not always fulfill these needs.

Sp517 Evergreen Trees For Screens And Hedges In The Landscape, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Screens and hedges are a popular way to create privacy or hide an undesirable view. They can be anything from a section of a fence to individually designed panels, brick walls or a wall of green plant material. Plantings are usually a less expensive way to create privacy than a fence or wall. Screens or hedges also offer additional advantages to many landscapes other than privacy. For example, they can frame a terrace or provide a backdrop to a herbaceous garden or other garden features.

Sp514 Small Trees For Fall Splendor, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Many cities, municipalities, utility companies and homeowners incur significant costs each year for maintenance or removal of large trees used in small urban areas. A preventative solution to the dilemma is to use small trees that will remain in scale with smaller urban landscapes and not interfere with power lines and in-ground utilities (i.e. cable, sewer, and telephone). Smaller trees will not provide the shade of large, dense-canopy trees, but are especially suited for courtyards, patios or framing a house.

Small trees are considered to mature in height at about 25 to 35 feet. No strict rule exists as to …

Pb1068-Hobby Greenhouses In Tennessee, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

For the avid gardener or plant lover, a hobby greenhouse can be like the icing on the cake. A greenhouse allows you to extend the gardening season by growing plants inside when outside weather conditions make plant growing impossible. It will also provide many hours of pleasure and relaxation while growing your favorite plants.

There are other factors you should consider. Does your plant growing interest span the whole year, or do you get excited about growing plants only during the spring gardening season? If you are only interested in growing annual flowers and vegetable plants, you may want to …

Sp291-E-Growing Sweet Corn In Home Gardens, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Corn is one of the most popular and diverse vegetables. Many types are grown, including field corn, ornamental corn, popcorn, sweet corn, several different supersweet corns and even broomcorn. Corn may be white, yellow, bicolor and many shades of red, blue or even black. Most home gardeners grow white, yellow or bicolor corn or supersweet corn, so this factsheet will be restricted to these.

The yield and quality of home-grown corn also vary more widely than the yield and quality of most other vegetables. The type of corn grown, cultural conditions of growth, harvest and post-harvest treatment all affect yield …

Distribution Of Fishes And Changes In Biotic Integrity In The New River, Tennessee, R. Brian Evans

Masters Theses

Electrofishing samples of fishes were obtained from forty-two localities in the New River system, Tennessee during summer and fall 1996. Eight of forty-two species collected represent new records from the New River: Notropis telescopus, Moxostoma macrolepidotum breviceps, M. carinatum, Lepomis auritus, L. gulosus, L. microlophus, Etheostoma cinereum, and Stizostedion vitreum. Temporal changes in the distribution of fishes were detected by comparing historical collection records with fish samples from 1996. Older records were also employed in the compilation of a modified index of biotic integrity (IBI) that was used to assess changes in fish assemblage health during the past twenty …

Sp284-B-Renovating Strawberries In The Home Garden, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The one production practice that Tennessee home gardeners most often neglect with their strawberry planting is renovation. Strawberry plantings are usually allowed to develop new runners with no effort to control weeds or to renew existing plantings. Many home gardeners feel mechanically removing weeds may disturb new strawberry plants and is a damaging practice. Unfortunately, failure to renovate is a more damaging practice when long-term production is desired.
