Ecological Correlates Of Protein Polymorphisms In A Desert And Non-Desert Population Of Belonia Saturata (Odonata: Anisoptera), Melissa Jean Hamilton

Theses Digitization Project

Two populations of the Big Red Skimmer Dragonfly, Belonia saturata (Odonata: Amisoptera), were studied to determine the thoracic temperatures maintained during flight, the presence of polymorphic enzyme systems, and to determine the differences in activity of glycerol-3-phosphate dehydrogenase between a desert and non-desert population.

Heat Shock Factor Gains Access To The Yeast Hsc82 Promoter Independently Of Other Sequence-Specific Factors And Antagonizes Nucleosomal Repression Of Basal And Induced Transcription, Alexander M. Erkine, C. C. Adams, T. Diken, D. S. Gross

Scholarship and Professional Work – COPHS

Transcription in eukaryotic cells occurs in the context of chromatin. Binding of sequence-specific regulatory factors must contend with the presence of nucleosomes for establishment of a committed preinitiation complex. Here we demonstrate that the high-affinity binding site for heat shock transcription factor (HSF) is occupied independently of other cis-regulatory elements and is critically required for preventing nucleosomal assembly over the yeast HSC82 core promoter under both noninducing (basal) and inducing conditions. Chromosomal mutation of this sequence, termed HSE1, erases the HSF footprint and abolishes both transcription and in vivo occupancy of the TATA box. Moreover, it dramatically reduces promoter chromatin …

G96-1302 Managing Varroa In The Midwest, Marion D. Ellis, Frederick P. Baxendale

University of Nebraska-Lincoln Extension: Historical Materials

There are important regional differences in varroa population dynamics and control. This NebGuide offers recommendations on varroa management for beekeepers in the Midwest.

Varroa management has become an essential aspect of successful beekeeping since the mite was first discovered in the United States in 1987. Unlike most parasites which coexist with their host, varroa eventually destroy honey bee colonies of European descent. A good understanding of this important bee parasite is essential for successful beekeeping.

Ec96-779 Lagoons For Management Of Livestock Manure, Gerald R. Bodman

University of Nebraska-Lincoln Extension: Historical Materials

A lagoon is a specifically designed manure storage facility. A properly designed lagoon also functions as a treatment system. Manure in any storage facility undergoes some biological decomposition. However, any decomposition of organic matter which occurs in a conventional storage is coincidental and not part of the design procedure or considerations.

The proper design of a lagoon gives special consideration to biological decomposition of organic matter. In fact, the design is intended to promote or enhance the breakdown of organic matter.

This publication discusses the types of lagoons. It covers the design, construction, and guidelines of maintaining a lagoon.

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses recommended practices to manage man-made chemicals in a domestic water supply. Many Nebraskans are concerned about the effects some of the man-made chemicals that have become part of everyday life may have on their water supply. As the name implies, these chemicals do not exist in nature but were made by man. With proper storage and use of these chemicals and with proper well construction, the risks to groundwater from the chemicals are low and the benefits are many. In some areas of the state, however, industrial solvents, manufacturing chemicals, ammunition wastes, pesticides and grain fumigants have …

G96-1298 Milk Urea Nitrogen Testing, Rick J. Grant, Dennis Drudik, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to properly test for MUN and interpret the results.

Milk urea nitrogen (MUN) analyses can be used as a signal, or "red flag", to point out potential problems in your feeding program. In particular, high MUN values reflect excessive dietary crude protein or low rumen degradable nonfiber carbohydrates (NFC). The NFC fraction, usually composed of starch and other sugars, can be low when insufficient grain is fed, or grain is improperly processed. Appropriate MUN testing over a period of several months to fine tune a feeding management program can result in:

1. precisely meeting nutritional requirements, …

Seeing Double: Crystal Structures Of The Type I Tnf Receptor, James H. Naismith, Barbara J. Brandhuber, Tracey Q. Devine, Stephen R. Sprang

Biological Sciences Faculty Publications

The crystal structure of the extracellular domain of the type I tumor necrosis factor receptor (sTNF-R1) has been determined to 2.25 Å at pH 7.5. We have also solved the structure of sTNF-R1 at pH 3.7. sTNF-R1 is an elongated molecule consisting of a linear combination of four cysteine-rich motifs. Interestingly, the crystal structure reveals two distinct dimers of the receptor. One dimer is formed by a parallel arrangement of receptors, the other by an antiparallel arrangement of receptors. In the parallel arrangement of the receptors, the tumor necrosis factor (TNF) binding face of the receptor is completely exposed to …

Scaling Of Muscle Composition, Wing Morphology, And Intermittent Flight Behavior In Woodpeckers, Bret W. Tobalske

Biological Sciences Faculty Publications

Existing theory and empirical evidence suggest that body size should have a profound influence upon the composition of flight muscles and the performance of intermittent flight in birds. I examine the relationships between functional morphology and intermittent flight behavior within a closely-related group of birds using six species of woodpeckers (Picidae): Downy Woodpecker (Picoides pubescens, 27.2 g), Red-naped Sapsucker (Sphyrapicus nuchalis, 47.4 g), Hairy Woodpecker (P. villosus, 70.5 g), Lewis' Woodpecker (Melanerpes lewis, 106.6 g), Northern Flicker (Colaptes auratus, 148.1 g), and Pileated Woodpecker (Dryocopus pileatus, 262.5 g). In woodpeckers with a body mass less than 100 g, the pectoralis …

Predicting Survival Of East Texas Loblolly And Slash Pine Plantations Infected With Fusiform Rust, J. David Lenhart, A. Beth Vaughn, Adams D.E.

Faculty Publications

Repeated measurement during 1982-1992 of East Texas Pine Plantation Research Project permanent plots in loblolly( Pinus taedaL .) and slash( Pinus elliottii Engelm.) pine plantations throughout East Texas were used to develop equations for predicting the future number of trees per acre. A typical condition of East Texas pine plantations is the incidence of fusiform rust( Cronatrium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme). A regression procedure for fitting nonlinear systems of equations was used to fit survival models that considered the possibility that trees with no rust galls on the stem could either (1) remain uninfected and alive, …

Red-Cockaded Woodpecker Nesting Success, Forest Structure, And Southern Flying Squirrels In Texas, Richard N. Conner, D. Craig Rudolph, Daniel Saenz, Richard R. Schaefer

Faculty Publications

For several decades general opinion has suggested that southern flying squirrels (Gluucomys volans) have a negative effect on Red-cockaded Woodpeckers (Picoides borealis) through competition for cavities and egg/nestling predation. Complete removal of hardwood trees from Red-cockaded Woodpecker cavity tree clusters has occurred on some forests because southern flying squirrel abundance was presumed to be associated with the presence and abundance of hardwood vegetation. In some locations, southern flying squirrels have been captured and either moved or killed in the name of Red-cockaded Woodpecker management. We determined southern flying squirrel occupancy of Red-cockaded Woodpecker cavities in loblolly (Pinus taeda)-shortleaf (P. echinata) …

Red-Cockaded Woodpeckers And Silvicultural Practice: Is Uneven-Aged? Silviculture Preferable To Even-Aged, D. Craig Rudolph, Richard N. Conner

Faculty Publications

The endangered red-cockaded woodpecker (Picoides borealis) has become a high-profile management issue in the southeastern United States. Suitable habitat consists of mature to old pine, or mixed pine-hardwood forest, with minimal hardwood midstory vegetation. Loss of habitat, detrimental silvicultural practices, and changes in the fire regime have resulted in small fragmented populations, most of which have been declining precipitously in recent decades (Costa and Escano 1989, Conner and Rudolph 1989). The current population of l0-12 thousand birds occurs across much of the original range from Virginia and Florida west to Oklahoma and Texas (James 1995). However, populations are restricted to …

Deer Use Of Riparian Zones And Adjacent Pine Plantations In Texas, Micah L. Poteet, Ronald E. Thill, R. Montague Whiting Jr., R. Lee Rayburn

Faculty Publications

The authors monitored white-tailed deer (Odocoileus virginianus) use of riparian zones (RZ’s) and adjacent pine plantations of 3 age classes (young, 1 to 3 years old; intermediate, 5 to 7 years old; and older, 9 to 13 years old) using radio telemetry for 2 years on a 1,300 ha study area near Alto, TX. Riparian zones comprised 22.0 percent of the area; young, intermediate, and older pine plantations comprised 19.1 percent, 45.7 percent, and 13.2 percent, respectively. Based on data from 4 to 9 deer the first year and 12 to 17 deer the second year, home ranges averaged 103, …

The Land Expectation Value Calculated In Timberland Valuation, T. J. Straka, Steven H. Bullard

Faculty Publications

Appraisers often use discounted cash flow (DCF) techniques to value timber and timberland. Land expectation value (LEV) is a standard DCF technique applied to many timberland situations. LEV calculates the value of bare land in perpetual timber production and is often used to value evenaged pine plantations. However, it is also useful in the valuation of immature timber stands and uneven-aged timber stands cut periodically. These models have wide applicability in timberland appraisal situations.

A New Species Of Gall Midge (Diptera: Cecidomyiidae) From Subterranean Stem Galls Of Licania Michauxii (Chrysobalanaceae) In Florida, Raymond Gagne, Kenneth Hibbard

USDA Systematic Entomology Laboratory

A new species of gall midge is described from subterranean stem galls on Licania michauxii Prance from Florida. The gall former is a new species of Lopesia and the first record of this genus in North America. The limits of Lopesia, a genus previously recorded only from South America and Africa, are enlarged to accept the new species. The species is described and illustrated. The pupa of this species is unique in Cecidomyiidae for its large, robust, dorsal abdominal spines that may be used in pushing through sandy soil after leaving the gall.
