An Assessment Of The Nebraska City Power Station Impingement Effects Relative To The Fishery Dynamics Of The Missouri River, J. Patrick Rhone, I. Cherko, L. G. Harrow, Allen B. Schlesinger

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Pursuant to National Pollutant Discharge Elimination System (NPDES) Permit No. NE 0111635, the Omaha Public Power District conducted an environmental monitoring program at the Nebraska City station. This study was undertaken to assess the effects of the station's cooling-water intake structure upon the aquatic biota of the Missouri River as required by Section 316(b) of the Federal Water Pollution Control Act. It included a study of fishes impinged on the intake structure's six traveling screens. From 29 May 1979 to 31 May 1982, daily fish impingement sampling occurred at 1200 and 2400 ± 2 hr. One of the traveling screens, …

A Bryological Survey Of The Southern Panhandle Of Nebraska, Linda L. Spessard

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Moss collections made in Arthur, Banner, Cheyenne, Deuel, Garden, Grant, Keith, Kimball, Morrill, and Scotts Bluff counties of Nebraska during the summer of 1981 comprised 19 species. The number of moss species now known in the southern Panhandle of Nebraska is 34 in addition to three liverworts.

Inclusive Fitness And The Practice Of Polyandry Among The Skidi Pawnee, Thomas E. Mcginnis

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The ethnohistorical record of the practice of polyandry among the Skidi Pawnee of the 19th century is examined from the perspective of the inclusive fitness model. The practice of temporary polyandry may have allowed males to maximize their inclusive fitness by insuring high paternity certainty. Younger brothers and nephews may have guarded the wives of older male relatives to prevent the wives from bearing children of unrelated males.

An Analysis Of Vegetation And Flora Of Field-Edges And Roadsides Of Agricultural Land In Eastern Nebraska, James E. Ducey, Catherine Wiederspan

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Five hundred sixty-seven hectares of agricultural cropland in east-central Nebraska were sampled during a vegetative analysis and botanical survey in the summer of 1979. One hundred eighteen species of plants in 39 families were recorded. The number of species recorded in the various edge-areas sampled ranged from six to 34. The differences noted were that species composition varied and some plants were present in small numbers in some areas and absent or undetected in others. Differences could be attributed to variations in slope, soil characteristics, and management of the areas sampled.

Trox Hamatus Robinson (Troginae) Using A Canthon (Scarabaeinae) Brood Ball And New Records Of North American Trox (Coleoptera: Scarabaeidae), Brett C. Ratcliffe

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Trox hamatus Robinson was observed feeding on an abandoned Canthon brood ball in southeastern Nebraska. Although some Aphodiinae and Scarabaeinae have been reported feeding on or stealing other scarabaeine dung balls, this represents the first reported observation of this behavior for a member of the Troginae. It is suggested that the brood ball was opportunistically used by the Trox, and the event is rare. In addition, new state records are provided for Trox aequalis Say, T. atrox LeConte, T. laticollis LeConte, and T. tesselatus (LeConte).

Nullisomic Tetrahymena. Ii. A Set Of Nullisomics Define The Germinal Chromosomes, E. Virginia Merriam

Biology Faculty Works

Crosses of a diploid Tetrahymena thermophila to a strain with a haploid germinal nucleus result in chromosome loss during meiosis in the haploid. The resulting monosomics can be made nullisomic by a special cross that induces homozygosis of a meiotic product of the germinal nucleus, but retention of the parental somatic nucleus. The creation and testing of single nullisomics for three of the five chromosome pairs and a triple nullisomic missing another pair is presented. Taken together, these strains make possible a series of crosses in which all but one of the chromosomes is missing in one parent. This set …

Protein Contributions Of The Male Accessory Organs To The Composition Of Human Seminal Plasma As Determined By High Resolution Two-Dimensional Electrophoresis, Edward E. Gaunt

Theses and Dissertations in Biomedical Sciences

Human Seminal Plasma was evaluated using a High Resolution Two-Dimensional Electrophoresis technique adapted by this laboratory. Seminal plasma from healthy volunteers with recently proven fertility were characterized using this technique to establish "normal" protein distribution patterns in the two-dimensional polyacrylamide gel slab. In addition, time studies were performed on selected specimens to determine the effects of liquefaction on seminal plasma protein composition within the first several hours after collection. Split ejaculates were collected for identification and elaboration of accessory organ components in the whole seminal plasma specimen. A more direct approach to accessory organ component analysis involved electrophoresis of semen …

Residue Trials, Herbicide Incorporation And Leaching Of Chlorsulfuron, T Piper

Experimental Summaries - Plant Research

Residue Trials: Breakdown rates have been established for trifluralin at Wongan Hills and Avondale over the past two seasons. The decay curve follows a hyperbolic curve rather than the expected exponential curve with constant half life, probably due to the considerable loss of chemical by volatalization in the first few days, before biological decomposition takes over as the main breakdown factor.

b) Herbicide Incorporation. Du Pont Zl96 fluorescent orange powder at 30 g/m2 could be readily seen when illuminated by 400 yw/cm2 of 365 nm UV radiation, and was successfully photographed on Ektachrome 400 ASA film with a 4 sec. …

Frequency Distribution Patterns And Partitioning Of Copper, Iron And Zinc In Selected Tissues Of The Black Mullet (Mugil Cephalus), Charles J. Venuto, John H. Trefry

Ocean Engineering and Marine Sciences Faculty Publications

Copper, iron and zinc concentrations were determined for muscle, gill and liver tissue from 45 black mullet (Mugil cephalus) collected in Turkey Creek, an embayment of the Indian River Lagoon, Florida. In the liver, Fe concentrations (2420+ 1040 jig/g, dry wt) were higher than for Cu (510 ± 350 fig/g) and Zn (330 ± 120ng/g). Gill tissue iron levels (380 ± 140/xg/g) were greater than those for Zn (96 ± 26 jtg/g) and Cu (6.3 ± 4.4 fig/g). Muscle tissue concentrations were lowest with Fe values (19 ± 15/tg/g) greater than thosefor Zn (13.5 ± 4.9 fig/g) and Cu (1.1 …

Of the 26 known species of the genus, 11 have been recorded from Nearctic rodents (Rausch and Rausch, 1973). In North America, Heligmosomoides spp. have been recorded not only from voles, but also from cricetids and murids. Heligmosomoides spp. characteristically inhabit the small intestine or cecum of their host, where they usually are found …

Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil

Avian Cognition Papers

The development of optimization theory has made important contributions to the study of animal behavior. But the optimization approach needs to be integrated with other methods of ethology and psychology. For example, the ability to learn is an important component of efficient foraging behavior in many species, and the psychology of animal learning could contribute substantially to testing and extending the predictions of optimal foraging theory.

The Transmission Of Learned Behavior: An Observational Study Of Father-Child Interactions During Fishing, Judy Diamond, Alan B. Bond

Papers in Behavior in Biological Sciences

Mechanisms of transmission of learned behavior were described in terms of the behavioral interactions between fathers and their children as they fished from a pier on Maryland’s Eastern Shore. Verbal and nonverbal behaviors were analyzed using hierarchical cluster analysis and the patterns of association in the behavioral repertoire were described in detail. Groupings of associated behaviors ranged from clusters suggestive of modeling or simple showing to complex combinations of behaviors involved in teaching. There were indications that the transmission behaviors varied with the content of the transmitted information and the role of the performer. Role differentiation in the transmission behaviors …

Visual Search And Selection Of Natural Stimuli In The Pigeon: The Attention Threshold Hypothesis, Alan B. Bond

Papers in Behavior in Biological Sciences

During visual search for samples of varying proportions of familiar, natural food grains displayed against a complex gravel background, pigeons exhibited “matching selection,” a tendency to overselect the more common grain. The matching selection effect was decreased at low levels of stimulus/background contrast and reversed when the grains were highly conspicuous. The results were consistent with the hypothesis that stimulus detectability should be enhanced by recent experience with a particular grain type, but they showed no convincing indications of a corresponding effect on the response criterion. An explanatory model, termed the attention threshold hypothesis, argues that the mean latency of …

Nickel: A Micronutrient Element For Hydrogen-Dependent Growth Of Rhizobium Japonicum And For Expression Of Urease Activity In Soybean Leaves, Robert V. Klucas, F. Joe Hanus, Sterling A. Russell, Harold J. Evans

Department of Biochemistry: Faculty Publications

Soybean plants and Rhizobium japonicum 122 DES, a hydrogen uptake-positive strain, were cultured in media purified to remove Ni. Supplemental Ni had no significant effect on the dry matter or total N content of plants. However, the addition of Ni to both nitrate-grown and symbiotically grown plants resulted in a 7- to 10-fold increase in urease activity (urea amidohydrolase, EC 3.5.1.5) in leaves and significantly increased the hydrogenase activity (EC 1.18.3.1) in isolated nodule bacteroids. When cultured under chemolithotrophic conditions, free-living R. japonicum required Ni for growth and for the expression of hydrogenase activity. Hydrogenase activity was minimal or not …

Reversible Dark-Induced Senescence Of Soybean Root Nodules, N. E. Pfeiffer, Nasir S.A. Malik, Fred W. Wagner

Department of Biochemistry: Faculty Publications

Nodule senescence was induced in intact soybean Glycine max. (L.) Merr., cv Woodworth plants by an 8-day dark treatment. Dark-induced senescence resulted in the complete loss of acetylene reduction activity, a 67% loss of total soluble protein, and an almost complete loss in total leghemoglobin of nodule extracts. Isoelectric focusing gels demonstrated a preferential loss of certain proteins, which was correlated with an increase in endoprotease specific activity toward azocasein. Nodules were completely green after the 8-day dark treatment. If plants were returned to a normal photoperiod after 8 days in the dark, nodules recovered from the dark treatment in …

Proteolytic Activity In Soybean Root Nodules: Activity In Host Cell Cytosol And Bacteroids Throughout Physiological Development And Senescence, Nancy E. Pfeiffer, Cecilia M. Torres, Fred W. Wagner

Department of Biochemistry: Faculty Publications

Root nodules were harvested from chamber-grown soybean (Glycine max L. Merril cv Woodworth) plants throughout development. Apparent nitrogenase activity (acetylene reduction) peaked before seeds began to develop, but a significant amount of activity remained as the seeds matured. Nodule senescence was defined as the period in which residual nitrogenase activity was lost. During this time, soluble protein and leghemoglobin levels in the host cell cytosol decreased, and proteolytic activity against azocasein increased. Degradative changes were not detected in bacteroids during nodule senescence. Total soluble bacteroid protein per gram of nodule remained constant, and an increase in proteolytic activity in …

Seed Predation And Seedling Mortality In The Recruitment Of A Shrub, Haplopappus Venetus (Asteraceae), Along A Climatic Gradient, Svata M. Louda

Svata M. Louda Publications

Haplopappus ventus is a characteristic shrub of the coastal sage scrub of southern California. Its relative frequency decreases rapidly and significantly from the coast to the central valleys of southern California. Insect damage to developing flowers and seeds is high (35-61%). Experimental exclusion of predispersal flower and seed predators caused a significant increase in the number of viable seeds released because of: (1) a decrease in insect-caused abortion of flower heads ( 11%), (2) an increase in pollination success (19%). and (3) a decrease in damage to developing seeds (104%). A significant and proportionate increase in the number of seedlings …

Gastrointestinal Helminths Of The Cougar, Felis Concolor L., In Northeastern Oregon, Robert L. Rausch, C. Maser, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

(larvae) (ca. 2%). In addition, undeveloped cestodes of the genus Taenia in 26 animals had lost rostellar hooks and could not be identified. Host-records, prevalence, and biological characteristics of some of the helminths are …

An Rna Virus In Autographa Californica Nuclear Polyhedrosis Virus Preparations: Gross Pathology And Infectivity, P. V. Vail, Thomas Jack Morris, S. S. Collier

School of Biological Sciences: Faculty Publications

The pathology and infectivity of an RNA virus infectious to Trichoplusia ni larvae was investigated. The enzyme-linked immunosorbent assay (ELISA) and weight depression were used as criteria for virus concentration in larval homogenates and live larvae, respectively. Infected larvae were severely stunted, weighing as little as 13 times less than uninfected individuals of the same age , yet appeared normal morphologically. The virus was found to cause only slight mortality at high concentrations. Infected larvae displayed the pathological stunting response down to a dose of 0.1 ng of virus. Larvae infected with doses 100 times lower did not show the …

Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

For the purposes of this book, the Northern Great Plains are defined as the states of Nebraska, North Dakota, and South Dakota. As a physiographic concept, the northern part of the great interior grasslands of North America is, of course, much broader in geographic extent than the Dakotas and Nebraska, but the three states lie in the heart of the region, and thus the title for this work seems appropriate. Our expectations in writing Mammals of the Northern Great Plains were to provide a comprehensive, yet semitechnical, treatmeat of free-living mammals that would prove useful to specialist and nonspecialist alike. …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This communication reports the smallest verified egg-carrying specimen of Callinectes sapidus. With a carapace 20 mm long by 47 mm wide, the female measures considerably less than most other mature individuals, but about the same as an average-sized individual infected with an adult specimen of the rhizocephalan Loxothylacus texanus.

Phytoplankton Studies Within The Virginia Barrier Islands. Iii. Phytoplankton Composition In A Saline Pond On Smith Island, Harold G. Marshall

Biological Sciences Faculty Publications

The phytoplankton that characterized the Smith Island pond was diverse, with several species of diatoms, dinoflagellates and blue-green algae dominant throughout the year. A total of 146 spp. were noted, predominantly composed of ultra and nanoplankters, that includes representatives from coastal waters. The island ponds are considered eutrophic habitats whose composition is influenced by overwash conditions and in turn introduce populations to surrounding pools and water channels.

Use Of Hydroelectric Dams To Control Evaporation And Salinity In The Colorado River System, Larry J. Paulson

Publications (WR)

The main stem reservoirs on the Colorado River comprise one of the largest and most heavily used freshwater bodies in the nation. These reservoirs (Lake Powell, Lake Mead, Lake Mohave and Lake Havasu) can store up to 53,590,400 acre-feet of water at their maximum capacities. Nonetheless, local water shortages still exist in some areas of the Colorado River Basin. There is also concern that salt concentrations are approaching levels that could severely affect municipal and agricultural uses. Water shortages will become even more acute as demands for water increase with continued urban and agricultural development in the basin. Water conservation …

Historical Patterns Of Phytoplankton Productivity In Lake Mead, Richard T. Prentki, Larry J. Paulson

Publications (WR)

Lake Mead was impounded in 1935 by the construction of Hoover Dam. The Colorado River was unregulated prior to then and therefore was subjected to extreme variations in flows and suspended sediment loads. Hoover Dam stabilized flows and reduced suspended sediment loads downstream, but Lake Mead still received silt-laden inflows from the upper Colorado River Basin. The Colorado River contributed 97% of the suspended sediment inputs to Lake Mead, and up to 140 x 1O⁶ metric tons (t) entered the reservoir in years of high runoff. Most of the sediments were deposited in the river channel and formed an …
