The Red-Cockaded Woodpecker: Interactions With Fire, Snags, Fungi, Rat Snakes, And Pileated Woodpeckers, Richard N. Conner, Daniel Saenz, D. Craig Rudolph Nov 2004

The Red-Cockaded Woodpecker: Interactions With Fire, Snags, Fungi, Rat Snakes, And Pileated Woodpeckers, Richard N. Conner, Daniel Saenz, D. Craig Rudolph

Faculty Publications

Red-cockaded woodpecker (Picoides borealis) adaptation to fire-maintained southern pine ecosystems has involved several important interactions: (I) the reduction of hardwood frequency in the pine ecosystem because of frequent tires, (2) the softening of pine heartwood by red heart fungus (Phellinus pini) that hastens cavity excavation by the species, (3) the woodpecker's use of the pine's resin system to create abarrier against rat snakes (Elaphe sp.), and (4) the woodpecker as a keystone cavity excavator for secondary-cavity users. Historically, frequent, low-intensity ground tires in southern pine uplands reduced the availability of dead trees (snags) that are typically used ...

Project Report No. 64, Observed Growth And Yield Of Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Shiaolin Cheng Apr 2004

Project Report No. 64, Observed Growth And Yield Of Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Shiaolin Cheng

Informal Project Reports

The amount of forestland in east Texas has been estimated at 11.8 million acres, with approximately 2.5 million acres classified as pine plantations. The majority ofthese plantations are owned by forest industry (71 percent), while non-industrial private forest landowners represent the next largest shareholder (23 percent). Pine plantations are typically managed to produce timber, so information is needed to make informed management decisions. Growth is one piece of information that managers often rely upon in their decision-making process.

Forest Landscape Changes In East Texas From 1974 To 2002, I-Kuai Hung, Jeffrey M. Williams, James Kroll, Daniel Unger Jan 2004

Forest Landscape Changes In East Texas From 1974 To 2002, I-Kuai Hung, Jeffrey M. Williams, James Kroll, Daniel Unger

Faculty Presentations

Timber production has been one of the most important industries in east Texas since the mid 19th century. For over 100 years, timber has represented one-third of all agricultural income in this region. In order to review forest landscape changes over time -- resulting from many years of management and investment -- historical satellite remote sensing data from 1974 to 2002 were used to determine landscape patterns and changes in four counties of east Texas : Angelina, Nacogdoches , San Augustine, and Shelby . Land cover was classified either as forest or non-forest and a land cover map was generated for seven unique time stages ...


Sterol Carrier Protein-2 Directly Interacts With Caveolin-1 In Vitro And In Vivo, Minglong Zhou, Rebecca D. Parr, Anca D. Petrescu, H. Ross Payne, Barbara P. Atshaves, Ann B. Kier, Judith M. Ball, Friedhelm Schroeder Jan 2004

Sterol Carrier Protein-2 Directly Interacts With Caveolin-1 In Vitro And In Vivo, Minglong Zhou, Rebecca D. Parr, Anca D. Petrescu, H. Ross Payne, Barbara P. Atshaves, Ann B. Kier, Judith M. Ball, Friedhelm Schroeder

Faculty Publications

HDL-mediated reverse-cholesterol transport as well as phosphoinositide signaling are mediated through plasma membrane microdomains termed caveolae/lipid rafts. However, relatively little is known regarding mechanism(s) whereby these lipids traffic to or are targeted to caveolae/lipid rafts. Since sterol carrier protein-2 (SCP-2) binds both cholesterol and phosphatidylinositol, the possibility that SCP-2 might interact with caveolin-1 and caveolae was examined. Double immunolabeling and laser scanning fluorescence microscopy showed that a small but significant portion of SCP-2 colocalized with caveolin-1 primarily at the plasma membrane of L-cells and more so within intracellular punctuate structures in hepatoma cells. In SCP-2 overexpressing L-cells ...


Radio Telemetry And Post-Emergent Habitat Selection Of Neonate Box Turtles (Emydidae: Terrapene Carolina) In Central Illinois, Patrick Forsythe, Beth A. Flitz, Stephen J. Mullin Jan 2004

Radio Telemetry And Post-Emergent Habitat Selection Of Neonate Box Turtles (Emydidae: Terrapene Carolina) In Central Illinois, Patrick Forsythe, Beth A. Flitz, Stephen J. Mullin

Faculty Publications

Although factors influencing turtle offspring prior to nest emergence have received considerable attention by researchers (Gutzke and Crews 1988; Janzen et al. 2000; Packard and Packard 1987), the activity of neonates following their emergence from the nest is poorly understood (but see Burger 1976; Butler and Graham 1995; Keller et al. 1997). Previous field research has produced valuable information on several aspects of neonate ecology for several species (Brewster and Brewster 1991; Butler and Sowell 1996; Janzen 1993). However, a thorough understanding of life history patterns for many species is absent, and some existing information is conflicting (e.g., Congdon ...


Evidence Of Red-Cockaded Woodpecker Nestling Displacement By Southern Flying Squirrels., Brent Burt, James R. Mccormick, Richard N. Conner, Daniel Saenz Jan 2004

Evidence Of Red-Cockaded Woodpecker Nestling Displacement By Southern Flying Squirrels., Brent Burt, James R. Mccormick, Richard N. Conner, Daniel Saenz

Faculty Publications

Red-cockaded Woodpeckers are unique among woodpeckers in that they excavate their roost and nest cavities entirely within living pines. Studies show that there is a propensity for squirrels to use unenlarged cavities, none have shown evidence of Red-cockaded Woodpeckers being killed by southern flying squirrels. However, we report an instance of two nestlings found dead at the base of the nest tree and 3 flying squirrels inside the nest cavity.


Batter's Choice: Lessons For Teaching Tactics In A Modified Striking/Fielding Game, Christina Sinclair Jan 2004

Batter's Choice: Lessons For Teaching Tactics In A Modified Striking/Fielding Game, Christina Sinclair

Faculty Publications

When played in their standard form, striking/fielding games are often a favorite among elementary students; yet they allow for only limited participation, which is contradictory to quality physical education. This article presents a sequence of lessons leading to Batter's Choice, a modified striking/fielding game, designed to maximize the attainment of tactical awareness, skill enhancement, and enjoyment by elementary children. Each lesson uses a tactical approach to involve students in solving a tactical problem within a game-like situation and then practicing the skills necessary to solve the problem. The tactical problems prepare students for game situations they will ...


Red-Cockaded Woodpecker Recovery: An Integrated Strategy, D. Craig Rudolph, Richard N. Conner, Jeffrey R. Walters Jan 2004

Red-Cockaded Woodpecker Recovery: An Integrated Strategy, D. Craig Rudolph, Richard N. Conner, Jeffrey R. Walters

Faculty Publications

Populations of the red-cockaded woodpecker (Picoides borealis) have experienced massive declines since European colonization of North America. This is due to extensive habitat loss and alteration. Logging of old-growth pine forests and alteration of the fire regime throughout the historic range of the species were the primary causes of population decline. Listing of the red-cockaded woodpecker under the Endangered Species Act of 1973, as amended, and increased emphasis on management of non-game species have resulted in efforts to recover remnant populations of the red-cockaded woodpecker in many parts of its historic range. Due to extensive research and adaptive management initiatives ...


Economic Analysis Of Pruning And Low-Density Management Compared To Traditional Management Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad Jan 2004

Economic Analysis Of Pruning And Low-Density Management Compared To Traditional Management Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad

Faculty Publications

Economic analyses were conducted to compare traditional loblolly pine (Pinus taeda L.) timber management to low-density management combined with pruning in East Texas. Soil expectation values were used to determine the financially optimal thinning and final harvesting schedules (including rotation length, and the timing, frequency and intensity of thinning). Two stumpage price assumptions were made: market price and premium price for pruned, clear sawlogs. Five site indices (50 to 90) and six real alternative rates of return (ARR) (2.5 to 15.0%) were employed. Results indicate that if the market price of sawtimber is $450/mbf, traditional management is ...

Daily Movements Of Female White-Tailed Deer Relative To Parturition And Breeding, Christopher E. Comer Jan 2004

Daily Movements Of Female White-Tailed Deer Relative To Parturition And Breeding, Christopher E. Comer

Faculty Publications

To assess how white-tailed deer (Odocoileus virginianus) herd demographics influence reproductive behaviors, we examined 24-h diel movements of female whitetailed deer relative to parturition and breeding in a low-density population with a near even sex ratio at the Savannah River Site (SRS), South Carolina. We conducted a series of intensive, 24-h radio-tracking periods of 13 females during spring and fall 2002. We compared daily range (ha), rate of travel (m/h), and distance between extreme daily locations (m), among the periods of pre-parturition and post-parturition and pre-, peak-, and post-rut. From pre-parturition to post-parturition, we observed decreases in diel range ...


Physiological And Growth Responses Of Midrotation Loblolly Pine To Treatments Of Fire, Herbicide, And Fertilizer, Emily J. Goodwin, Lisa M. Marino, Hans H. Williams, Brian P. Oswald, Kenneth W. Farrish Jan 2004

Physiological And Growth Responses Of Midrotation Loblolly Pine To Treatments Of Fire, Herbicide, And Fertilizer, Emily J. Goodwin, Lisa M. Marino, Hans H. Williams, Brian P. Oswald, Kenneth W. Farrish

Faculty Publications

The objectives of this study were to examine the effects of fertilizer and understory vegetation control (herbicide and prescribed fire) on mature tree physiology and to link observed physiological responses with tree growth. Photosynthetic rate (photosynthesis), transpiration, stomatal conductance, stem diameter, and crown area were measured in two midrotation loblolly pine plantations in East Texas. Rates of photosynthesis, E and gs for the midsummer measurements were significantly reduced by fertilizer treatments on both sites. Drought in east Texas during the last 3 years may have influenced this result. Trees receiving fire at the site with a comparatively more dense live ...


Nantucket Pine Tip Moth Control And Loblolly Pine Growth In Intensive Pine Culture: Two-Year Results, David Kulhavy, Jimmie L. Yeiser, L. Allen Smith Jan 2004

Nantucket Pine Tip Moth Control And Loblolly Pine Growth In Intensive Pine Culture: Two-Year Results, David Kulhavy, Jimmie L. Yeiser, L. Allen Smith

Faculty Publications

The Nantucket pine tip moth, Rhyacionia frustrana (Comstock) (NPTM), is an important pine regeneration insect in the Eastern and Southern United States (Berisford 1987). Larval feeding in meristematic tissue of young pines causes significant damage, particularly in areas where forest regeneration favors its proliferation (Yates and others 1981). Southeastern industrial forestry currently emphasizes establishment of large, homogeneous pine plantations to maximize production of wood and fiber. This forest management practice also creates optimal conditions for phytophagous insects, whose sole or primary hosts are pine trees. Increased damage by NPTM following vegetation control treatments may include improved suitability of pine tissue ...

Oustar: A Premixed Blend Of Velpar Df+Oust Xp For Herbaceous Weed Control And Enhanced Loblolly Pine Seedling Performance, Jimmie L. Yeiser, Andrew W. Ezell

Faculty Publications

Six tests were established comparing the herbaceous weed control (HWC) and resultant loblolly pine (Pinus taeda L.) seedling performance from treatments of Oustar (0, 10, 13, 16, 19 ounces product acre-1), and industry standards (Velpar L+Oust 32+2; Arsenal+Oust 4+2 both in ounces product acre-1). Sites were prepared prior to planting with: burn only, chemical only, mechanical only, or mechanical and chemical methods. Oustar (13 ounces) and industry standards provided similar weed control and seedling performance. The low rate (10 ounces) of Oustar applied to sandy loam soils receiving chemical preparation and plowing prior to planting provided ...


History And Evaluation Of The Mcintire-Stennis Cooperative Forestry Research Program, D. H. Thompson, Steven H. Bullard Jan 2004

History And Evaluation Of The Mcintire-Stennis Cooperative Forestry Research Program, D. H. Thompson, Steven H. Bullard

Faculty Publications

On October 10, 1962, President John Kennedy signed PL 87-788 (Appendix A) now known as the McIntire-Stennis Cooperative Forestry Research Program. After 40 years, this formula-based cooperative program continues to provide the base support for much of the forestry research conducted at 65 public forestry institutions. While still important, the proportion of McIntire-Stennis research sponsored over this time period has decreased. Other funding sources, such as competitive grants through the Cooperative State Research, Education, and Extension Service and other government agencies along with special grants appropriated by Congress, now finance a higher proportion of forestry research as shown in Figure ...


How Are Investment Returns Affected By Competition Control And Southern Oak Seedling Survival?, D. L. Grebner, A. W. Ezall, D. A. Gaddis, Steven H. Bullard Jan 2004

How Are Investment Returns Affected By Competition Control And Southern Oak Seedling Survival?, D. L. Grebner, A. W. Ezall, D. A. Gaddis, Steven H. Bullard

Faculty Publications

Increasing numbers of landowners are establishing hardwood plantations to satisfy their management objectives. Despite a dearth of research on competition control and its effects on initial hardwood plantation survival and investment returns, this study examines alternative competition control regimes for southern oak establishment. The analysis includes estimates of land expectation value for comparing alternatives. Our results suggest that greater returns can be achieved for southern oaks during both good and bad rainfall years, using methods that maximize survival through competition control.

Comparison Between Regenerators And Non-Regenerators In Mississippi: A Discriminant Analysis, Kathryn G. Arano, Ian A. Munn, John E. Gunter, Steven H. Bullard, Max L. Doolittle Jan 2004

Comparison Between Regenerators And Non-Regenerators In Mississippi: A Discriminant Analysis, Kathryn G. Arano, Ian A. Munn, John E. Gunter, Steven H. Bullard, Max L. Doolittle

Faculty Publications

Nonindustrial private forestland (NIPF) landowners in Mississippi who recently harvested timber were surveyed to examine their regeneration behavior. Differences between regenerators and nonregenerators were investigated by looking at the different factors affecting reforestation decisions. A discriminant analysis was used to identify factors that were useful in differentiating between regenerators and nonregenerators. Ownership size; sociodemographic characteristics such as income, education, place of residence, and age; awareness of existing government incentive/assistance programs; and participation in educational programs were significant variables in differentiating between regenerators and nonregenerators. Landowners who own larger timberlands had a higher propensity to engage in regeneration activities after ...


Improving Southern Oak Seedling Survival Can Boost After-Tax Investment Returns, Donald L. Grebner, Deborah A. Gaddis, Andrew W. Ezell, Steven H. Bullard Jan 2004

Improving Southern Oak Seedling Survival Can Boost After-Tax Investment Returns, Donald L. Grebner, Deborah A. Gaddis, Andrew W. Ezell, Steven H. Bullard

Faculty Publications

Private forest landowners have many reasons for managing their timberlands- from intensive timber production to wildlife habitat to family recreation. An exciting forestry development is the establishment of oak plantations on agricultural land. Both state and federal governmental assistance programs can provide part of the initial investment involved in forest establishment costs. Unfortunately, there are few existing studies to help landowners decide if the investment will be profitable.
