Plant Identification For The Rio Grande Delta, William P. Kuvlesky, Jr.

United States Fish and Wildlife Service: Publications

The Rio Grande Delta of Texas is one of the most diverse ecological areas in Texas. The area is favorite among ornithologists due to the presence of many species that winter there or migrate through the area. Similarly, the Delta harbors several rare mammals, reptiles, amphibians, and a host of invertebrates, which are found nowhere else in North America. Most ecologists attribute this unique faunal diversity to the great variety of vegetation that characterizes the Rio Grande Delta. Accurately identifying the vegetation is therefore an important aspect of field research performed in the region.

Gray Wolf Status In North Dakota, Daniel S. Licht, Louis E. Huffman

United States Fish and Wildlife Service: Publications

Recent occurrences and reports of gray wolves (Canis lupus) in North Dakota have generated public interest and created demands on management agencies. We summarized reports of wolves in North Dakota received from the public and government personnel, and evaluated suitability of habitat for wolves. We suggest that in recent years dispersing wolves have sporadically occurred in all quarters of the state except the southwest, and non-dispersing wolves have occurred in the Turtle Mountains region in north-central North Dakota. Habitat data from the 1,500 km² Turtle Mountains physiographic region, bisected by the North Dakota/Manitoba border, suggest the potential …

Evolution Of A Field Biologist, Karen A. Smith

United States Fish and Wildlife Service: Publications

In My Double Life, biologist Frances Hamerstrom reveals her evolution from an affluent childhood in early 1900s Boston to a rugged and spirited field biologist. She writes in first person with short, easy-reading chapters about her life, generally in chronological order from childhood to present. The anecdotes are concise, witty, and spiced with humor in her characteristic, blissful confidence. There are many unique black-and-white photographs reproduced, as well as pen-and-ink illustrations mostly by her artist-daughter, Elva Hamerstrom Paulson. Half of the book's chapters are borrowed from earlier works, in particular her award-winning Strictly for the Chickens (1980). This new …

Pathogenesis Of Bovine Herpesviruses In Vitro, C. C.L. Chase, S. Stone, K. Bialas, C. Carlson, W. Wiese, L. Braun

South Dakota Beef Report, 1996

Bovine herpesviruses cause acute disease in cattle. Bovine herpesvirus 1 (BHV-1 or IBR) is a respiratory virus, while bovine herpesvirus 5 (BHV-5) affects the brain and causes a viral encephalitis. Studies in the laboratory showed no difference in the growth rate of BHV-1 or BHV-5 in blood vessel, brain, or kidney cells. The ability of BHV-1 to cause cells to die is not caused by apoptosis (programmed cell death). Further studies on the pathogenesis of bovine herpesviruses need to be conducted to improve control and prevention measures.

Long-Term Protection From Bovine Viral Diarrhea Virus In Feedlot Cattle, C. C.L. Chase, J. Hanson, R. Fraser, L. Braun, S. Anderson, D.J. Hurley

South Dakota Beef Report, 1996

Bovine viral diarrhea virus (BVDV) causes respiratory and reproductive disease. The duration of immunity of an inactivated vaccine (Virashield 5: Grand Laboratories, Freeman, SD) was measured in two challenge studies. In both studies the vaccinated animals demonstrated fewer clinical signs when challenged with Type II BVDV at 11 or 13 months post vaccination. These results indicate that an inactivated vaccine administered properly can protect animals against disease up to at least a year post vaccination.

The map units were based on field observations and extrapolation from existing surveys.

Wildlife Damage Management (Wdm) In The Northern Utah Adc District, United States Department Of Agriculture, Animal And Plant Health Inspection Service, Animal Damage Control

All U.S. Government Documents (Utah Regional Depository)

Across the United States, wildlife habitat has been substantially changed as human populations expand and land is used for human needs. These human uses and needs often compete with wildlife which increases the potential for conflicting human/wildlife interactions. In addition, segments of the public strive for protection for all wildlife; this protection can create localized conflicts between human and wildlife activities.

Evapotranspiration From A Saltcedar-Dominated Desert Floodplain: A Scaling Approach, S. D. Smith, A. M. Sala, Dale A. Devitt

Life Sciences Faculty Research

The purpose of this study was to investigate evapotranspiration (ET) from a variety of scales (leaf to landscape) in saltcedar-dominated floodplain vegetation along the lower Virgin River of southern Nevada. Leaf-level gas exchange indicated that saltcedar exhibits similar stomatal conductance as the sympatric phreatophytes arrowweed, mesquite, and willow. However, sap flow in saltcedar was higher per unit sapwood area than the other species, suggesting that it maintains higher leaf area per unit sapwood area. At the stand level, saltcedar ET was found to exceed potential ET early in the summer when soils were moist and the water table was near …

Genetic Dissection Of The Morphological Evolution Of Maize, John Doebley

Aliso: A Journal of Systematic and Floristic Botany

Maize (Zea mays ssp. mays) and its wild progenitor, teosinte (Z. mays ssp. parviglumis) differ dramatically in inflorescence and plant architecture despite the fact that their evolutionary divergence occurred within the past 10,000 years or less. To elucidate the genetic control of the morphological differences between maize and teosinte, my colleague and I employed quantitative trait locus mapping with molecular markers. Results indicated that most of the variation in plant and inflorescence morphology between maize and teosinte can be explained by five restricted regions of the genome. In this paper, characterization of three of these regions …

G96-1306 Feeding Dairy Cows To Reduce Nitrogen, Phosphorus, And Potassium Excretion Into The Environment, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses feeding strategies to optimize dairy cow performance while minimizing negative environmental impacts.

Reducing N, P and K Excretion--The Challenge

Increasingly, our society demands livestock production systems that not only produce economic, high-quality food products, but also minimize negative environmental impacts. Feeding management has improved continuously and helps explain increases in milk production averages. The future challenge for dairy producers and nutritionists will be to properly formulate rations for high production levels while simultaneously minimizing the environmental impact of excessive N, P and K excretion in the urine and manure. A realistic approach will be to keep formulation …

Assessment Of The Suitability For Agriculture Of The North-West Packsaddle Area Kununurra, N Schoknecht

Resource management technical reports

A brief assessment of the suitablility for agriculture of about 260 ha in the North-west Packsaddle area was conducted in early September 1993. Nine map units based on soil and landform were identified, and their suitability for broadscale flood irrigated agriculture and spray or trickle irrigated horticulture assessed. The map units are based on field observations and extrapolation from existing surveys. The map was prepared at a scale of 1:20,000 and is only accurate at that scale.

Postnatal Development Of The Neural Retina In A South American Opossum: Monodelphis Domestica, Tracy L. Soltesz

Theses, Dissertations and Capstones

Postnatal retinal development was studied in a marsupial opossum, Monodelphis domestica using light microscopy and 3H-thymidine autoradiography. For the light microscopic study, opossum neonates at 1, 3, 7, 14, 21, 25 and 28 days of age were euthanized, fixed and processed into paraffin sections for hematoxylin and eosin staining. The distinct ganglion cell layer, first observed on postnatal day (P) 7, was separated from the outer neuroblasts by the inner plexiform layer. The neuroblast layer was divided into inner and outer nuclear layers on P25 by the presumptive outer plexiform layer, indicated by discrete intercellular spaces located between the nuclear …

G96-1276 Creep Feeding Growing Horses, Kathleen P. Anderson, Pete G. Gibbs

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the benefits and implications of creep feeding horses during the growing period of development.

Creep feeding, providing a place where foals can eat without interference from the mare and other horses, should be used if foals are to grow at optimum rates. Creep feeders are used to provide a nutritionally balanced, digestible concentrate to young nursing foals before weaning. The practice of creep feeding serves to supply nutrients beyond what a foal receives from mare's milk. And, creep feeding minimizes foals' intake of broodmare feed which often lacks the concentrated amounts of protein and minerals relative to …

G96-1277 Pine Moths, Mark O. Harrell, Frederick P. Baxendale, J. Ackland Jones

University of Nebraska-Lincoln Extension: Historical Materials

Pine moths can seriously damage pine trees. This NebGuide helps you recognize damage and symptoms, identify the pest, and choose a control.

Pine moths are serious pests of pines in Nebraska. Larvae (caterpillars) damage trees by tunneling just beneath the bark of the trunk and branches (Figure 1), most commonly on the trunk just below a branch. The tunnels they make can girdle the trunk or branches or physically weaken them so they are easily broken by wind or snow (Figure 2). Heavily infested trees are often deformed and are sometimes killed.

G96-1280 Drinking Water: Iron And Manganese, David L. Varner, Sharon Skipton, Delynn Hay, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses recommended practices to manage iron and manganese in a domestic water supply. Iron and manganese are non-hazardous elements that can be a nuisance in a water supply. Iron and manganese are chemically similar and cause similar problems. Iron is the most frequent of the two contaminants in water supplies; manganese is typically found in iron-bearing water.

Infection And Fungal Development Of Tubakia Dryina On Sweet Gum (Liquidambar Styraciflua), Josephine Taylor, Shane Clark

Faculty Publications

Infection and fungal development of Tubakia dryina were investigated on leaves of sweet gum using a combination of microscopic techniques. Conidia of T. dryina adhered to the leaf surface and formed septate germ tubes. Germ tubes terminated in small appressoria that formed directly over epidermal cells. Intra- and intercellular hyphae ramified extensively throughout the leaf tissue. Host cells associated with the infection site became necrotic and collapsed, resulting in macroscopic disease symptoms.

Dietary Overview Of Hemidactylus Turcicus With Possible Implications Of Food Partitioning, Daniel Saenz

Faculty Publications

A stomach content analysis was conducted on Hemidactylus turcicus, the Mediterranean gecko, from 19 April 1990 to 15 October 1990, on the campus of Stephen F. Austin State University, Nacogdoches, Texas. Geckos (N = 167) were placed into four size groups based on snout-vent-length (5 29 mm, 30-39 mm, 40-49 mm, and z 50 mm) and three microhabitat groups based on perch height (those occupying perch sites < 1.52 m, 2 1.52 m to 5 3.05 m, and > 3.05 m). Stomach contents were analyzed and sex, size, and microhabitat groups were compared using Schoener's percent overlap index. Volumetrically, the most important prey items taken were Orthoptera, Lepidoptera, and Isopoda. Geckos of …

Douglas-Fir Beetle, Richard F. Schmitz, Kenneth E. Gibson

The Bark Beetles, Fuels, and Fire Bibliography

The Douglas-fir beetle (Dendroctonus pseudotsuqae Hopk.) infests and kills Douglas-fir throughout most of its range in western United States British Columbia and Mexico. Occasionally western larch trees are infested when growing among Douglas-fir under attack. Attacks in standing larch are always unsuccessful, while those in freshly felled larch are usually successful and brood emergence is equivalent to that in Douglas-fir. Douglas-fir beetles normally kill small groups of trees, but during outbreaks 100 tree groups are not uncommon (fig. 1). Losses can be devastating during periodic outbreaks, such as four that occurred in western Oregon and Washington from 1950 through 1969, …
