Evaluation Of Instream Flow Methodologies For Fisheries In Nebraska, Phil Hilgert

Nebraska Game and Parks Commission: Publications

Five instream flow methods were applied to a variety of streams within the state of Nebraska. These were (1) the Tennant method, (2) a modification of the Tennant method, (3) IFG1 A, a single cross-section average-parameter method, (4) the Incremental method, using the WSP hydraulic simulation program, and (5) the Incremental method, using the IFG4 hydraulic simulation program.

Each method was applied following standard published procedures, and instream flow recommendations were developed for the streams addressed using each method separately. Evaluation of the methods showed that the modification of the Tennant method overcame some of the deficiencies of the Tennant …

Habitat Use By Nesting And Roosting Bald Eagles In The Pacific Northwest, Robert G. Anthony, Richard L. Knight, George T. Allen, B. Riley Mcclelland, John I. Hodges

United States Fish and Wildlife Service: Publications

The American bald eagle (Haliaeetus leucocephalus) was designated our national symbol in 1782. Since that time, populations of the species have declined due to a combination of factors including habitat loss, shooting, and environmental pollutants. As a result, in 1978 the U.S. Department of Interior officially listed the species as endangered in 43 of the 48 contiguous states and threatened in Oregon, Washington, Michigan, Wisconsin, and Minnesota. The bald eagle is protected under the Endangered Species Act, Migratory Bird Treaty Act, and the Bald and Golden Eagle Protection Act. These pieces of legislation protect the species from direct …

Waterfowl Production At Malheur National Wildlife Refuge, 1942-1980, John E. Cornely

United States Fish and Wildlife Service: Publications

Malheur National Wildlife Refuge (NWR), Harney County, Oregon, is an important breeding area for Pacific Flyway Waterfowl. Trumpeter swans (Olor buccinator), Canada geese (Branta canadensis), and 14 species of ducks nest at Malheur NWR. The refuge is one of the most important redhead (Aythya americana) nesting areas in the western United States. Malheur NWR was established by President Theodore Roosevelt in 1908, primarily as a nesting area for migratory birds. The refuge also serves as an important migration stop for thousands of waterfowl and other migratory birds. Originally the refuge was called Malheur Lake …

Status Of The Habitat Evaluation Procedures, Mel Schamberger, William B. Krohn

United States Fish and Wildlife Service: Publications

The 1970s was a decade of increased awareness of environmental problems, and emphasis was placed on the development of procedures for predicting impacts of proposed developmental activities on natural systems. Impact assessment has evolved from a focus on species numbers, human use, species richness, and related methods to include the investigation of habitat as a supplemental or alternative approach to environmental planning, mitigation, species management, and impact assessment (Schamberger 1979, U.S. Fish and Wildlife Service 1980a, 1980b). The impetus for habitat-based assessment techniques came primarily from two sources: (1) environmental legislation requiring noneconomic project evaluations; and (2) an awareness within …

Influence Of Cooperative Wildlife And Fishery Units On Graduate Education And Professional Employment, Rollin D. Sparrowe

United States Fish and Wildlife Service: Publications

In June 1982, several private conservation organizations will join the Iowa State University, and the Iowa Conservation Commission, in a 50-year celebration of the Cooperative Research Unit concept. The first Cooperative Wildlife Research Unit began there in 1932 in response to a recognized need for trained biologists and scientific information in the field of wildlife conservation. The unique partnership between federal, state, university, and private entities that resulted, evolved into the current nationwide program. There are currently 21 wildlife units, 26 fishery units, and 3 combined fish and wildlife units at 31 universities in 29 states (Figure O. The Fishery …

Aquatic Biota Of Bank Stabilization Structures On The Missouri River, North Dakota, Ralph M. Burress, Douglas A. Krieger, C. H. Pennington

United States Fish and Wildlife Service: Publications

Biological and physical data were collected from nine habitats on the Missouri River near Washburn, North Dakota. Sampling was conducted from mid-July to mid-October 1979 to compare the relative values of the habitats for fish and macroinvertebrates.

Permeability, Underpressures, And Convection In The Oceanic Crust Near The Costa Rica Rift, Eastern Equatorial Pacific, Roger N. Anderson, Mark D. Zoback

United States Geological Survey: Staff Publications

In situ permeability and pore pressures were measured 200 m deep beneath the top of the oceanic crust at DSDP site 504B. These measurements have relevance for the transition from convective to conductive heat flow on the south flank of the Costa Rica Rift. Conventional 'slug' and constant rate injection tests were made below a hydraulic packer set at various depths in the hole. The packer was first set in a massive flow unit 37 m below the sediment-basement interface. The bulk permeability of the 172.5m of pillow basalts and basaltic flows below the packer was found to be about …

Personal Computers And Behavioral Observation: An Introduction, John H. Flowers, Daniel W. Leger

Department of Psychology: Faculty Publications

Some fundamental aspects of observational data are outlined, and some basic issues in implementation of small computers in observational research are discussed.

Some Simple Apple Ii Software For The Collection And Analysis Of Observational Data, John H. Flowers

Department of Psychology: Faculty Publications

Two general-purpose software packages for collecting and analyzing observational data from a variety of settings are discussed. One package is designed for coding mutually exclusive behavioral states using the Apple’s keyboard as an input device. The other is designed to monitor temporally overlapping behaviors, and it makes use of the Apple II’s built-in game-control button inputs to indicate up to three behavioral states that may occur simultaneously.

The Plant Pathogenic Corynebacteria, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

The plant pathogenic corynebacteria are a fascinating group of bacteria that produce effects as diverse as any in the microbial world, ranging from wilts to abnormal growths. Several new pathogens have been discovered since this group was reviewed by Jensen (75), Starr (157), and Lelliott (96). Most subsequent reviews have dealt with taxonomy. The areas covered in this review necessarily reflect my biases and limitations. However, this review attempts to be comprehensive in some areas, and it calls attention to other areas that would benefit from more detailed investigation.

In Search Of A Diversity Ethic For Wildlife Managemen, Fred B. Samson, Fritz L. Knopf

United States Department of Agriculture Wildlife Services: Staff Publications

As the century nears its end and demand for food and competition for land escalate, a most important issue facing conservationists will be the preservation of a mosaic of habitats in which can be preserved a representative cross-section of native species. The need to resolve this issue is emphasized in the Global 2000 Report to the President (Council on Environmental Quality 1980) which predicts that, worldwide, 500,000 to 2 million species will become extinct by the year 2000 and that the rate will increase from one per day in 1980 to one per hour by century's end (Myers 1979). Although …

Uterine Blood Flow And Uterine Arterial, Venous And Luminal Concentrations Of Oestrogens On Days 11, 13 And 15 After Oestrus In Pregnant And Non-Pregnant Sows, S. P. Ford, R. K. Christensen, J. J. Ford

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

Concentrations of oestradiol-17β and oestrone were measured in the uterine arterial and venous blood of anaesthetized sows on Days 11, 13 or 15 of the oestrous cycle or of pregnancy. Uterine arterial blood flow and the amounts of oestradiol-17β and oestrone in uterine flushings were determined in the same animals. In pregnant animals arterial and venous concentrations were significantly different (P < 0·05) for oestradiol-17β on Days 11 and 13 and for oestrone on Day 15. Uterine content of both steroids was consistently greater in pregnant than in non-pregnant animals with a peak on Day 13. Uterine arterial blood flow increased from Day 11 to 13 of pregnancy then declined (P < 0·08)by Day 15; no change in uterine blood flow occurred on the corresponding days of the oestrous cycle.

Androstenedione, Dehydroepiandrosterone And Testosterone In Ovarian Vein Plasma And Androstenedione In Peripheral Arterial Plasma During The Bovine Oestrous Cycle, T. H. Wise, D. Caton, W. W. Thatcher, A. Rami Lehrer, M. J. Fields

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

Catheters were placed in the carotid artery via a facial artery (n = 12) and in the ovarian vein (n = 12), and, in conjunction, electromagnetic flow meters were placed around the ovarian artery (n = 6) in cyclic beef cows. Androstenedione was quantitatively the highest and dehydroepiandrosterone the lowest of the ovarian androgens measured. Ovarian androgens were correlated positively with each other (P < 0·05)but not with ovarian blood flow or day of the cycle. There was a trend for spikes of androgen release (ovarian vein concentration × ovarian blood flow) from the ovary to be greatest during the period of decreasing progesterone and CL regression. However, only with testosterone were spikes of release different (Days -13 to -9 < Days -8 to -4;P < 0·05;Day 0 = oestrus). The dynamic changes in ovarian androgens noted in this study were compatible with the concept of continuous follicular development and atresia throughout the oestrous cycle.

Food Habits Of The Red Fox In Nebraska, Douglas G. Powell, Ronald M. Case

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Food habits of red foxes (Vulpes vulpes) in Nebraska were deter· mined by analysis of 234 fox stomachs obtained from fur dealers during October 1978 through February 1979. Mammals were found most frequently (84%) and constituted the majority (77.4%) of the volume of food items. Cottontails (Sylvilagus floridanus) and jack· rabbits (Lepus sp.) were the most important items consumed based on frequency of occurrence (45.8%) and volume (49.2%). Remains of birds were difficult to identify, but ring-necked pheasants (Phasianus colchicus) occurred in 6.9% of the stomachs and comprised 8.4% of the volume of items …

A Fossil Snake (Elaphe Vulpina) From A Pliocene Ash Bed In Nebraska, J. Alan Holman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A fossil snake from the San tee local fauna was collected in August 1979 by J. Alan Holman, Raymond A. Holman, and Michael R. Voorhies. The Santee local fauna (University of Nebraska State Museum Locality Kx-111) is exposed in a road cut on the south side of the Lewis and Clark Reservoir of the Missouri River, 17.7 km ENE of the junction of the Niobrara and Missouri rivers, Knox County, Nebraska, at Latitude 42° 49' N, 97° 50' W. The matrix of this locality consists of an ash that fell on the area about 4.5 m.y.B.P. during the latter part …

A Cancer Of Environmental And Occupational Etiology And A Thigh Tumor Described By Sir Percivall Pott In The Eighteenth Century, Anne J. Krush

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Percivall Pott was born in London, England 26 December 1713. His father died when he was four, leaving Mrs. Pott with Percivall and a daughter by a previous marriage. Pott's education was thereafter financed by one of Mrs. Pott's cousins, Dr. Wilco x, Bishop of Roches· ter. Although Pott became proficient in classical literature, and although Dr. Wilcox hoped that he would choose a career in theology, he chose a career in surgery instead and was bound as an apprentice to Dr. Nourse, a surgeon at St. Bartholomew's Hospital in 1729. He spent 58 years at this hospital, resigning from …

The Improbability Of Inductive Logic, Edward F. Becker

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

In some arguments, premises and conclusions are so related that if the former are true, so, necessarily, are the latter. Arguments having this property are said to be valid; those which lack it are said to be invalid. Some invalid arguments are worthless, but others are not. Among the latter are many arguments used by scientists, such as the arguments by which laws are inferred from their instances. These arguments, one wants to say, do not guarantee the truth of their conclusions, but they nevertheless make them more probable. Though not valid, they are inductively strong. Thus there arises the …

Solitude And Communion In Miau, Eva Margarita Nieto

Spanish Language and Literature Papers

Miau continues to be a challenging work because of the complexity of its problems and techniques. The symbolic title has been studied as a key to the metaphoric tension of both structure and characterization within the novel; Don Ramón de Villaamil's deplorable economic situation reveals the narrator's and the author's critical perception of the false and hypocritical urban society that surrounds him. Above all, his suicide, constructed as it is within a quasi-heretical (certainly not orthodox) interpretation of the mandate of the Almighty, has both fascinated and puzzled critics.² Yet all of these problems, character dehumanization and animalization, the …

Book Review: Estimating The Size Of Animal Populations, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The array of methods available to estimate animal populations is as bewildering as its literature is overwhelming. Consequently, a short book that promises to "outline the procedures involved" and give "a concise account of the theory" is warmly welcomed. This book offers all of that in a short text designed for both undergraduate and graduate students.

Book Review: Populist Systems: A General Introduction, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The profession of wildlife management has had an incomplete evolution into wildlife ecology if we are to believe that names of university departments accurately reflect current status. This transition implies less emphasis on doing and greater emphasis on understanding. I term the evolution incomplete because wildlife biologists have not fully embraced all the tools of ecology. One such tool is population ecology. Certainly we have studied wildlife population dynamics, but often with a narrow focus, viewing as unique a particular group of animals in a certain area at some specified time. Less often have we endeavored to draw together our …

Resource Management Thrusts And Opportunities: Fish And Wildlife-A Fuller Dimension To Improved Resource Management, John B. Crowell, Jr.

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

It has been a little more than a year since President Reagan was inaugurated, and a little less time than that since I was confirmed and sworn in as assistant secretary of agriculture. We have moved to establish and implement some changed emphases in our resource management programs. So, by now there should be little mistake about our intent to improve natural resource management on the national forests. We intend to increase the productivity of these resources without corresponding increases in federal appropriations. We intend to generate increased receipts to the U.S. Treasury by emphasizing revenue-producing activities such as timber …

Livestock And Riparian-Fishery Interactions: What Are The Facts?, William S. Platts

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The riparian environment has become a key consideration in the planning and management of the public lands. This highly productive habitat receives many uses, some of which conflict with one another. Because there are conflicts that need immediate attention, range and fishery managers are making complicated, hurried decisions, often without the benefit of adequate knowledge or experience. In addition, interpretations emerging from riparian studies are often confusing and contradictory, inhibiting the manager's decision-making abilities.
Leopold (1974) stated that fish and wildlife habitat in western rangeland has experienced and is experiencing a steady deterioration under livestock grazing. The same year, Heady …

Habitat Classification-Assessments For Wildlife And Fish, Hal Salwasser, William B. Krohn

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Comprehensive planning and management of natural resources require the assessment of existing and future conditions offish and wildlife. Fish and wildlife, hereafter referred to as wildlife resources, can be inventoried and assessed either in terms of animals or habitats. Both approaches are useful given certain management objectives. For example, population inventories in concert with other data, are often used to assess the impacts of hunting. In contrast, habitat inventories are used to evaluate the impacts of grazing, or other land and water uses, on wildlife resources. Our objective is not to compare or contrast the two approaches, but to focus …

Needs For And Approaches To Wildlife Habitat Assessment, Jack Ward Thomas

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

For many years prior to 1969, wildlife was essentially defined, in the practice of governmental bodies, as those species hunted for sport, trapped for furs, controlled to accomplish human objectives, or of particular aesthetic value. Governmental management of these species was based on funding obtained from or supported largely by clearly identified constituencies.
Universities evolved specialized programs in wildlife biology and management to produce the knowledge and trained professionals to meet these needs. Many such programs were oriented to training in zoology which emphasized the animal and populations while paying less attention to habitat.
As a result, most wildlife research …

Response Strategies In The Radial Arm Maze: Running Around In Circles, Sonja I. Yoerg, Alan C. Kamil

Papers in Behavior in Biological Sciences

The effects of the size of the central arena on the use of response strategies by rats on an eight~arm elevated maze were examined. The size of the central arena had no effect on accuracy, but the use of adjacent arms increased significantly with a larger central arena, regardless of the size of arena to which rats were first exposed. These results are interpreted in terms of foraging efficiency.

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf

Avian Cognition Papers

An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.

Teton Wildlife: Observations By A Naturalist, Paul A. Johnsgard

Papers in Ornithology

The diversity of wildlife in Grand Teton National Park and its environs draws millions to the valley of Jackson Hole every year, but few are the visitors who are able to observe individual species over the course of several seasons. Paul Johnsgard, a noted naturalist who has written many books on the waterfowl of the world, here integrates his own observations with those who have studied Teton wildlife in the past. The result is a compassionate, simple reconstruction of the lives of a few individuals from spring through early autumn.

Etho-Ecological Apects Of Hybridization In The Tetraonidae, Paul A. Johnsgard

Paul Johnsgard Collection

A review of records of intrafamilial hybridization in the Tetraonidae indicates that at least half of the potential natural hybrid combinations that could occur in this family on the basis of known distribution patterns actually have been reported at least once. These include 15 interspecific hybridization combinations that involve 12 species and all of the genera currently recognized by taxonomists. The three most commonly reported hybrid combinations all involve lek-forming species of grouse as parental types, while the remaining 12 combinations are all considerably rarer and involve lek-forming parental species in 7 cases, promiscuous but solitary species in 6 cases, …
