Distribution Of Sandhill Cranes In The North Platte River Valley: 1980 And 1989, Martin J. Folk, Thomas C. Tacha

Proceedings of the North American Crane Workshop

We observed the abundance, diurnal distribution, and habitat use of sandhill cranes (Grus canadensis) in the North Platte River Valley (NPRV) in 1989 for comparisons to similar data from 1979 to 1980. Sandhill cranes traveled farther from nocturnal roosts to diurnal feeding sites and use of the NPRV was lower in 1989 as compared to 1979~80. Presence of cranes in corn stubble and pasture increased from 1980 to 1989, while presence in alfalfa and palustrine wetlands decreased. Plowing of corn stubble fields and drought conditions in 1989 may have influenced crane distribution, abundance, and habitat use.

Factors Influencing The Future Of Whooping Crane Habitat On The Platte River In Nebraska, Craig A. Faanes

Proceedings of the North American Crane Workshop

Lands along 86 km of the Platte River in Nebraska were designated by the U.s. Department of Interior as critical habitat for the endangered whooping crane (Grus americana) in 1978. The designation established the legal basis for the continued protection of lands critical to the survival and recovery of whooping cranes. Currently there are 14 federal, state, and local water projects planned for the Platte River system. If completed, total withdrawal would be about 80% of the remaining 30% of the original flow. In this paper I summarize those projects and discuss their potential impact on whooping crane habitat. …

Distribution And Status Of Greater Sandhill Cranes In Nevada, Marcus S. Rawling

Proceedings of the North American Crane Workshop

Nesting habitat of the Lower Colorado River Valley Population (LCRVP) of greater sandhill cranes (Grus canadensis tabida) was censused in northeastern Nevada from 1983 through 1986. Ninety-two nesting pairs and 594 cranes were located. Eighty-two percent were observed in central Elko County. Cranes were marked from 2 summer range locations and from the Lund, Nevada traditional spring migration stopover with patagial streamers. Cranes marked on summer range wintered on the lower Colorado River, in the Imperial Valley near Brawley, California and on the Gila River in southwestern Arizona. Cranes marked at the stopover were observed on summer range …

13.2.15. Human Disturbances Of Waterfowl: Causes, Effects, And Management, Carl E. Korschgen, Robert B. Dahlgren

Waterfowl Management Handbook

Human disturbances of waterfowl can be intentional or unintentional. They may result from overt or directed activities or may be ancillary to activities not initially thought to be of concern to birds. Some of these disturbances are manifested by alertness, fright (obvious or unapparent), flight, swimming, disablement, or death. Therefore, persons responsible for waterfowl management areas should be aware of the problems from human disturbance and should design management and facilities that increase public appreciation of waterfowl.

In the last 20 years, the intensity of water-based recreation increased drastically, especially on inland waters. Waterfowl are wary, seeking refuge from all …

Overview Of The Symposium On Walleye Stocks And Stocking, Daryl G. Ellison, William G. Franzin

Nebraska Game and Parks Commission: Staff Research Publications

Rising angler interest in walleye Stizostedion vitreum, a general decline in natural recruitment in some waters, and increasing demands for stocking have produced a need to evaluate stocking strategies. Such evaluations were the subject of the Walleye Stocks and Stocking Symposium summarized herein. Among walleye stocking evaluations reported in the symposium, 32% of fry stockings, 32% of small-fingerling stockings, and 50% of advanced-fingerling stockings were considered successful. Further improvement in stocking success requires research into the factors that affect survival. Matching stocking times and places to appropriate food resources appears to be a key element in successful introductions of …

Nebraska's Vanishing Species, Greg Wingfield

Nebraska Game and Parks Commission: Staff Research Publications

Nebraskans are blessed with a rich heritage - friendly, hard-working people, unique landforms and diverse natural resources, including native species of plants and animals. Unfortunately, an irreplaceable part of this heritage, our threatened and endangered species, is vanishing.
Simply stated, a threatened species is one likely to become endangered. An endangered species is one so rare that it is in danger of becoming extinct. Extinction is the loss of a species from this world.

Textiles And Identity In Prehistoric Southwestern North America, Lynn S. Teague

Textile Society of America: Symposium Proceedings

This study focuses on the place that textiles had in the lives of people in the central Greater Southwest after about A.D.1000, and in particular on the development of two distinctive traditions in cloth that co-existed in the central Southwest during this period. These traditions were the predecessors of two equally distinctive historic textile traditions, those of the puebloan people of the Colorado Plateau and those of the O'Odham in the Sonora Desert of southern and central Arizona.

Clothing is a basic means of indicating social identity, and in the prehistoric Southwest provides some of our most intriguing evidence of …

Comparison Of Restriction Fragment Length Polymorphisms In Chloroplast Dna Of Five Leafy Spurge (Euphorbia Spp.) Accessions, Scott Nissen, Robert A. Masters, Donald Lee, Martha Rowe

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Chloroplast DNA (cpDNA) restriction fragment length polymorphisms (RFLPs) were analyzed to assess genetic variation and relatedness among selections of North American and Eurasian leafy spurge. Leafy spurge accessions from Nebraska, Montana, Russia, Italy, and Austria were evaluated. Total DNA was extracted from young leaves and digested with the restriction endonuclease, EcoRI. CpDNA fragment patterns were determined by Southern blot analysis using mung bean cpDNA probes. Colinearity between the mung bean and leafy spurge chloroplast genomes was indicated by the observation that common fragments were hybridized by adjacent probes. Minimum estimates of chloroplast genome size for the five leafy spurge …

Toward A Policy Of Destruction: Buffaloes, Law, And The Market, 1803-83, Andrew Isenberg

Great Plains Quarterly (through 2013)

When the United States purchased the Louisiana Territory from France in 1803, it acquired an abundance of natural resources that would help fuel American economic expansion for the rest of the nineteenth century. The fertile soil of the tallgrass prairie would support one of the most productive agricultural regimes in the United States. Lumberers would cut longleaf, shortleaf, loblolly, and slash pine from the west bank of the Mississippi River between New Orleans and St. Louis. Miners would discover deposits of gold and lead in Colorado, Montana, and South Dakota.¹ Yet the most prominent resource of the Louisiana Territory …

Suicide: Unpredictable And Unavoidable—Proposed Guidelines Provide Rational Test For Physician's Liability, Phyllis Coleman, Ronald A. Shellow

Nebraska Law Review

The physician who treats a suicidal patient faces real life-or-death decisions. The primary decision depends on his professional evaluation of the likelihood that his patient will take his own life. If the physician concludes that suicide is imminent, medical ethics and the law require he take steps to protect his patient. Failing to take appropriate protective action exposes the physician to legal liability. The physician owes a duty to his patient, but defining parameters of this duty and methods to satisfy it are not clear. Neither the legal system nor current medical knowledge or practice establishes guidelines to aid the …

Circulating Gonadotrophins During A Period Of Restricted Energy Intake In Relation To Body Condition In Heifers, M. S. Roberson, T. T. Stumpf, M. W. Wolfe, Andrea S. Cupp, N. Kojima, L. A. Werth, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

Beef heifers, 13 months old, were fed to achieve high (7·6 + 0·2 units) or low (3·9 ± 0·1 units) body condition by feeding them one of two diets for 20 weeks. During week 17 of the growth phase, all heifers were ovariectomized. From week 20 to week 27 (restriction phase), all heifers were fed a daily diet containing 0·071 MJ metabolizable energy kg^-1 body weight. At weekly intervals throughout the restriction phase, blood samples were collected at 10-min intervals for 11 h to determine the pattern of secretion of luteinizing hormone (LH), the amount of LH released in …

Modulation Of Luteinizing Hormone And Follicle-Stimulating Hormone In Circulation By Interactions Between Endogenous Opioids And Oestradiol During The Peripubertal Period Of Heifers, M. W. Wolfe, M. S. Roberson, T. T. Stumpf, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

The aim of this study was to determine whether the decline in oestradiol inhibition of circulating luteinizing hormone (LH) and follicle-stimulating hormone (FSH) during the peripubertal period of heifers is associated with a change in opioid modulation of LH and FSH secretion. Opioid inhibition of LH secretion was determined by response to administration of the opioid antagonist naloxone. Prepubertal heifers (403 days old) were left as intact controls, ovariectomized or ovariectomized and chronically administered oestradiol. Control heifers were used to determine time of puberty. Three weeks after ovariectomy, four doses of naloxone (0·13-0·75 mg kg^-1 body weight) or saline …

Steady-State Amounts Of Α- And Luteinizing Hormone (Lh) Β-Subunit Messenger Ribonucleic Acids Are Uncoupled From Pulsatility Of Lh Secretion During Sexual Maturation Of The Heifer, M. S. Roberson, M. W. Wolfe, T. T. Stumpf, D. L. Hamernik, Andrea S. Cupp, L. A. Werth, N. Kojima, Roger J. Kittok, H. E. Grotjan, J. E. Kinder [email protected]

Department of Animal Science: Faculty Publications

Our primary objective for this study was to determine whether steady-state amounts of α - and LH β-subunit mRNAs in the anterior pituitary are altered during sexual maturation in the bovine female. A secondary objective was to determine whether 17β-estradiol (E₂) alters amounts of LH subunit mRNAs before onset of puberty. Heifers (7 mo old) were assigned to one of three treatments: 1) ovariectomized (OVX, n = 16); 2) OVX and administered E₂ (OVXE, n = 16); or 3) ovary-intact (INTACT, n = 20). Pituitaries were collected at an estimated 120 days before onset of puberty (prepuberty) …

G92-1084 Culture Of Cole Crops, Laurie Hodges, R.E. Neild

University of Nebraska-Lincoln Extension: Historical Materials

How to grow successfully broccoli, brussels sprouts, cabbage, cauliflower, and kohlrabi.

Cole crops, which include broccoli, brussels sprouts, cabbage, cauliflower, and kohlrabi, can be successfully grown on most soils if drainage is good and the crop is supplied with adequate water and nutrients, particularly nitrogen. Light-textured soils usually produce earlier crops but heavier soils hold more moisture and tend to produce crops that hold quality longer at maturity.

Cole crops have shallow root systems. Inadequate moisture may cause small cauliflower heads to form prematurely. Rainfall or irrigation following a prolonged dry spell may cause splitting of cabbage and kohlrabi. Supplemental …

G92-1104 Getting Started In Beekeeping, Marion D. Ellis, Frederick P. Baxendale

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on beginning beekeeping in Nebraska.

Beekeeping in Nebraska

There are approximately 700 beekeepers in Nebraska operating about 115,000 colonies of bees. Annual honey production in the state ranges from 5 to 11 million pounds depending on weather conditions and available flora. The honey from each area is a unique blend of nectars from the available flora. In a good area under favorable conditions, a properly managed colony can produce 100 pounds or more of honey. The six-year average (1986-1991) for honey production per colony in Nebraska is 75 pounds.

Of far greater importance is the role …

G92-1099 Estimating Effective Rainfall, Joel E. Cahoon, C. Dean Yonts, Steven R. Melvin

University of Nebraska-Lincoln Extension: Historical Materials

How irrigators can estimate effective rainfall, and use that estimate to schedule irrigations properly. Scheduling irrigation based on crop demand (see NebGuide G85-753 Irrigation Scheduling Using Crop Water Use Data, on the checkbook method) requires an estimate of effective precipitation or rainfall. Effective rainfall estimates are also important for planning cropping sequences in both dryland and irrigationd crop production. Effective rainfall is the amount of rainfall stored in the crop root zone. Rainfall that runs off the soil surface or passes through the root zone does not contribute to crop growth and yield. There are two steps to estimating effective …

G92-1110 The Thirteen-Lined Ground Squirrel: Controlling Damage, Dallas R. Virchow, Scott E. Hygnstrom

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the physical characteristics, habits and management of the thirteen-lined ground squirrel.

Description

Thirteen-lined ground squirrels (Spermophilus tridecemlineatus) are common throughout the Great Plains. They have many common names such as "thirteen-liner" or "striped gopher." "Gopher" is a misnomer because true (pocket) gophers (Geomys bursarius and Thomomys talpoides) belong to another family of rodents.

13.2.7. Identifying The Factors That Limit Duck Production, James K. Ringelman

Waterfowl Management Handbook

Low duck populations in the late 1980’s and early 1990’s prompted unprecedented action from the natural resources community. Agencies and private organizations that were traditionally involved with waterfowl management redoubled their efforts, in the process forming partnerships with groups that were relatively new to the waterfowl management arena. Many resource managers who have had relatively little experience with waterfowl habitat management now find themselves expected to manage duck populations for increased production. Decades of waterfowl research and management experience have provided them with many potential management tools. Unfortunately, the absence of general guidelines for directing waterfowl management actions has put …

13.2.14. Management Of Habitat For Breeding And Migrating Shorebirds In The Midwest, Jan Eldridge

Waterfowl Management Handbook

Shorebirds have always relied on the extensive network of natural wetlands from Texas to North Dakota. This network has now been fractured by wetland drainage and agriculture to the point where suitable wetlands are absent in much of the Midwest. Habitat loss and the resulting risk of population decline highlight the importance of management of shorebirds on refuges, hunting clubs, and preserves for both breeding and migrating species.

Because shorebirds, like waterfowl, depend on wetlands throughout the year, the loss of natural wetlands in the Midwest poses a real threat. Unfortunately, shorebirds are slow to recover from population declines caused …
