Pest Management Strategies For Longhorn Army Ammunition Plant And An Assessment Of Aerial Radiography For Hazard Rating Pine Stands For Southern Pine Beetle Infestation, James Matthews

Electronic Theses and Dissertations

Currently, sampling or hazard rating insects at military installations is limited. The use of aerial videography is a relatively new technology and is currently used for aerial surveys and is being developed for hazard rating for southern pine beetle. The purpose of this study was to apply existing sampling methods for various insects and disease at the Longhorn Army Ammunition Plant in Karnak, Texas and to test the effectiveness of aerial videography for hazard rating pine stands for southern pine beetle. Based on field data, stands were generally rated as moderate for southern pine beetle; moderate to high infestations of …

Influence Of Planting Density On Diameter And Height In East Texas Pine Plantations, Young Jin Lee, J. David Lenhart

Faculty Publications

The response of diameter and height of unthinned planted stands ofloblolly (Pinus taeda L.) and slash (Pinus elliottii Eng elm.)pine in East Texas to different classes of planting densities were analyzed. After tracking the development ofdiameterand heightfor 15yron a setofpennanentplots representing a broad range of plantation parameters, average diameter and average height trends were observed. For both species, average diameter values were significantly larger with lower planting densities. 1n contrast, average height growth is insensitive to planting density at younger age classes for loblolly and at older age classes for slash pine plantations.

Impacts Of Three Timber Stand Improvement Thinning Options On Low Quality Southern Mixed-Hardwood Stands, Brian P. Oswald, Thomas H. Green

Faculty Publications

The impact of three thinning options (strip, single-tree selection, and strip with selection between strips) on lowquality southern mixed-hardwood stands was evaluated in northern Alabama. Although stand level comparisons showed no significant differences between options, individual dominant trees benefitted from the thinning treatments, exhibiting increased basal area growth during the period of the study. Intermediate treatments such as these thinning options may provide landowners with sufficient growth of selected high-quality trees to warrant the more intensive management activities on similar sites as utilized in this study.

Initial Investigation Of Height-Diameter Relationships Of Dominant Trees In The Mixed Hardwood Bottomland Forests Of East Texas, Brian P. Oswald, A. Gordon Holley, Leslie A. Dale, Gary D. Kronrad

Faculty Publications

Three to five dominant trees from each of 445 ten-factor variable radius inventory points were utilized to evaluate the height- diameter relationships of 13 species or genera found on bottomland hardwood sites throughout east Texas. Regression analysis was performed using the linear model such that height = (30 + (31 x (d.b.h.). The species were placed into six groups: (1) pines (Pinus taeda and P. enchinata) ; (2) water oak/willow oak/white oak/swamp chestnut oak (Quercus nigra)/(Q. phe//os)/(Q. alba)/(Q. michauxi1) ; (3) blackgum/laurel oak/overcup oak (Nyssa sylvatica)/(Q. laurifolia)/(Q. lyrata); (4) ash/maple (Fraxinus spp.)/(Acerspp.); (5) hickories (Carya spp.), and (6) elms (Ulmus …

First-Year Survival And Growth Of Bareroot, Container, And Direct-Seeded Nuttall Oak Planted On Flood-Prone Agricultural Fields, Hans Michael Williams, Monica N. Craft

Faculty Publications

Container and 1-0 bare root Nuttall oak ( Quercus nuttallii, Palmer) seedlings were hand-planted, and acorns were direct- seeded, in a Sharkey soil (very fine, montmorillonitic, nonacid, thermic, Vertie Haplaquepts). The seedlings and seed were planted in January, February, March, and June, 1993. Flooding, to a depth of 2 meters, occurred on the study site from late March to late May. Seedlings planted in June were not flooded. Regardless of planting date, mean first-year survival for container seedlings was greater than 80 percent. Overall mean survival for bareroot seedlings was about 40 percent and direct-seeding survival was 30 percent. Bareroot …

Effects Of Stock Type And Fall Fertilization On Survival Of Longleaf Pine Seedlings Planted In Lignite Minespoil, Mary Anne Mcguire, Hans Michael Williams

Faculty Publications

One-year-old longleaf pine (Pinus palustris Mill.) seedlings were hand-planted in January 1996 on an east Texas minespoil site. Effects of two seedling stock types and four levels of preplanting fall fertilization on seedling survival were evaluated. Fertilizer treatments consisting of a single application of ammonium nitrate (73 kilograms per hectare N), phosphorus (81 kilograms per hectare P), diammonium phosphate (73 kilograms per hectare N, 81 kilograms per hectare P), or control (no fertilizer) were applied to bare-root and container seedlings in November 1995. Root growth potential, the ability of a seedling to initiate and elongate new roots when placed into …

Red-Cockaded Woodpecker Nest-Cavity Selection: Relationships With Cavity Age And Resin Production, Richard N. Conner, Daniel Saenz, D. Craig Rudolph, W. G. Ross, David Kulhavy

Faculty Publications

ABSTRACT.--We evaluated selection of nest sites by male Red-cockaded Woodpeckers (Picoides borealis) in Texas relative to the age of the cavity when only cavities excavated by the woodpecker were available and when both naturally excavated cavities and artificial cavities we available. We also evaluated nest-cavity selection relative to he ability of naturally excavated cavity trees to produce resin, which is used by the woodpeckers to maintain a barrier against predation by rat snakes (Elaphe spp.), Longleaf pines (Pinus palustris) selected by breeding males as nest trees produced significantly greater resin yields at 2, 8, and 24 h post-wounding than cavity …

Higher Prices And Shorter Rotations: Good News For Pine Plantation Investors, But . . ., Steven H. Bullard, Bob Daniels

Faculty Publications

Southern pine markets have changed dramatically in recent years. Our focus here is the changing forest economy, new price expectations, and new technologies for growing and utilizing pines. The major changes in southern pine markets are good news for forest landowners concerned with timber production-higher prices are increasing pine plantation returns, rotation lengths are decreasing, and the value of land in pine production is increasing.

Inter-And Intraspecific Interaction Rates Of Three Species Of Lemurs (Subfamily Lemurinae) In An Enclosure At The Memphis Zoo And Aquarium, Stephen J. Mullin

Faculty Publications

The use of mixed-species exhibits in zoological parks may influence the types and rates of interactions between individuals housed in such enclosures. Inter-and intraspecific behavioral interactions were observed for three species of lemurs (ring-tailed lemur, Lemur catta; black lemur, Eulemur macaco macaco; and black-and-white ruffed leumur, Varecia variegata variegata; in an enclosure designed to simulate characteristics of their natural habitat. Intraspecific interactions occurred more frequently than interspecific interactions, and little aggression was observed, either between or within species. Intraspecific interactions among black lemurs increased with decreasing ambient temperature. Black lemurs performed more intraspecific mutual contacts than either agonistic behaviors or …

The Foraging Ecology Of The Gray Rat Snake (Elaphe Obsoleta Spiloides)-Visual Stimuli Facilitate Location Of Arboreal Prey, Robert J. Cooper, Stephen J. Mullin

Faculty Publications

We examined the responsiveness of adult gray rat snakes to avian prey in enclosures that simulated natural habitat conditions. Subjects searched for arboreal nest contents in the presence or absence of a bird model flown so as to simulate avian provisioning behavior. In the absence of the model, gray rat snake latency to capture prey was over 92 % greater than when searching for nest contents with the model. Snakes responded to model flight by turning their heads in the direction of its movement. We conclude that gray rat snakes perceive relatively distant visual cues from prey, and that nest …
