Interstate Fisheries Management Problems: The Case Of Striped Bass, Richard Randall Schneider

Marine Affairs Theses and Major Papers

The striped bass (Morone saxatilis), or rockfish, fishery has been important both commercially and recreationally for decades along the Atlantic seaboard. In recent years, though, the fishery has undergone a serious decline and, as a result, has elicited considerable public concern. Although specific reasons for the decline have not been pinpointed, it is clear that inconsistent management practices within the range of striped bass have done little to help the fishery's condition. An anadromous species, striped bass spawn in the fresh water reaches of estuaries, after which many of the individuals return to the coastal ocean. In the Atlantic, the …

Bobwhite Thesaurus, Thomas G. Scott

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

The Bobwhite Thesaurus was assembled with the belief that it  would make the voluminous literature more accessible. Publications  on the bobwhite have become so numerous and have been published  in so many different places that today's bobwhite researcher is seldom able to conduct the library search required to unearth all pertinent material. This results in failure to acknowledge and use prior  findings.

An effort has been made to seek out and index all publications  issued prior to 1983 that contain information on the bobwhite. All  publications found have been included irrespective of their apparent  worth excepting anonymous papers. Publications which …

A Phylokaryotypic Evaluation Of The Genus Tursiops (Family Delphinidae), Melissa Kay Estes

Dissertations and Theses

In an attempt to correlate genetic data with possible species delineation, this study investigates the presence of chromosomal variants between the North Atlantic bottle nose dolphin, Tursiops truncatus, and the North Pacific bottle nose dolphin, T. gilli. Blood samples were obtained from oceanaria in the United States. Location of capture was correlated with karyotype to compare chromosome morphology with geographic range.

Control Of Insect Pests In Recent Mammal Collections, S. L. Williams, Hugh H. Genoways, D. A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

A review is made of numerous insecticides to determine their suitability for use in Recent mammal collections. Factors determining their value were based on human safety, ability to protect specimens without adverse effects, and other considerations. The more favorable insecticides to use in mammal collections include Dowfume 75, sulfuryl fluoride. dimethyldiclorovinyl phosphate, paradichlorobenzene, carbon dioxide, and naphthalene. Insecticides that are considered less favor able because of many limitations included aldrin, dieldrin, arsenic, borax, mitin, ethylene oxide, methoxychlor, methyl bromide, and pyrethrum. There are some insecticides that should never be used because of extreme health and/or fire hazards. These include carbon …

Community Ecology, Robert K. Rose, Elmer C. Birney

Biological Sciences Faculty Publications

COMMUNITIES with Microtus tend to be structurally simple, usually grasslands or tundra, and to have no more than two species of Microtus and rarely more than six species of small mammals. Microtus often dominates both numerically and in total small mammal biomass, especially at higher latitudes. The small mammal community is most influenced by Microtus through its fluctuations in density, and thus also in biomass, by its relatively high level of diurnal activity, and by its year-round activity. Other species of small mammals may be adversely affected because Microtus usually is larger and behaviorally dominant and also because the mere …

The Analysis And Use Of Methodologies For The Study Of The Diets Of Long-Eared Owls From Three Environments In North Central Oregon, John M. Barss

Dissertations and Theses

Part I of this study presents a procedure for standardization of pellet analysis methodologies which improves estimation of prey biomass and determines the number of pellets needed to estimate prey diversity indices. The procedure was developed to provide a simple, easily replicated methodology for the study of pellets which also retains maximal data recorded from pellet analysis. A sample size of ten Long-eared Owl pellets was found adequate to calculate diversity indices with no significant loss of accuracy when compared to total pellets recovered from beneath a roosting site. Analysis of the total sample of pellets from a specific roost …

An Exceptional "Fall" Migration Of Shorebirds Along The Big Bend Reach Of The Platte River, Gary R. Lingle, Thomas E. Labedz

Nebraska Bird Review

The Big Bend reach of the Platte River extends about 80 miles from Overton to Chapman, Nebraska. This area is characterized by braided channels with numerous riverine islands bordered by cottonwoods (Populus deltoides) and willows (Salix spp.) along the high banks. Habitat between the high banks consists of open water, barren sandbars and mudflats, herbaceous islands, shrub islands, and floodplain forest.

Prolonged summer flows during 1983 were among the highest recorded this century; in excess of 20,000 cfs (cubic feet per second). Spring 1984 also consisted of high flows resulting in much scouring and shifting of …

Nesting Common Moorhen In Lancaster County, William C. Garthright

Nebraska Bird Review

On 6 July 1984, at 6 PM CDT, I saw a Common Moorhen at the Capitol Beach marsh, in Lincoln. It was about 10 yards to the north when I first saw it, and I could see the red facial shield and red bill with yellow tip, the yellow legs, a thin white horizontal line along the side, and prominent white patches along either side of dark undertail coverts. It acted mildly agitated, and swam away from me but stayed in the vicinity.

At 7 the next morning I waded into the pond at that spot. This time I saw …

1984 Fall Field Day

Nebraska Bird Review

The 1984 Fall Field Day was held (officially) from noon to noon, 6/7 October, at the4-H Camp at Halsey National Forest. The weather was not the best—light rain early Saturday morning, only a couple of short showers in the afternoon, and no rain Sunday, both days dull and gray. But the attendance was good—87 were officially registered—but the added manpower could not make up for the lateness in the season and the poor weather—the tally on or near the Forest was only 81. In addition, 4 species (marked N) not recorded in the Forest were seen by a party that …

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson

Publications (WR)

Several limnological studies have been conducted in Lake Mead during the past decade. The recent studies clearly show that most of Lake Mead is deficient in nutrients, especially phosphorus, and very low in productivity. The reservoir-wide average total phosphorus concentration for 1981 - 1982 was only 9 mg/m³. This is below levels found In most oligotrophic lakes and reservoirs. Algal biomass, as measured by chlorophyll-a, averaged only 1.5 mg/m³. That also places Lake Mead in the oligotrophic range. Transparency, as measured by a Secchi disc, averaged 9-5 m in Lake Mead during 1981-1982. That far exceeds …

Book Review: Mammals Of The Northern Great Plains By J. K. Jones, Jr., D. M. Armstrong, R. S. Hoffmann, And C. Jones, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Mammals of the Northern Great Plains is an attractive clothbound book that comes in a colored dust jacket showing a female pronghorn walking in the snow. The book is produced in a double-column format set in a 47½ by 32½ pica typebed (I personally do not like the unjustified right-hand margins on both columns). The book contains 206 figures most of which are set in a single column. Of the 206 figures, 80 are distribution maps, 104 are photographs mostly of living animals, 20 are drawings used to illustrate keys or points made in the text, and two are maps …

Effect Of Castration On Plasma Luteinizing Hormone Concentrations In Prepubertal Boars, R. J. Kittock, J. E. Kinder, R. K. Johnson

Department of Animal Science: Faculty Publications

Mean concentrations and the occurrence of pulsatile release of luteinizing hormone (LH) were determined in 14-wk-old crossbred boars (50.5 ± 1.5 kg) after bilateral or unilateral castration at 10 wk of age. Blood was collected at 10-min intervals for 5 h. Then gonadotropin releasing hormone (GnRH; 40 / μg) was given and sampling was continued at 5-min intervals for 1 h. Compared with intact boars, bilateral castration increased (P<.001) mean LH (982 ± 56 vs 389 ± 56 pg/ml), pulsatile releases of LH (7.0 ± .6 vs 2.0 ± .6 pulses/5 h) and LH pulse amplitude (617 ± 29 vs 360 ± 58 pg/ml). Unilaterally castrated boars did not differ from intact boars in any of the above measures of LH secretion. Testis weight increased more between 10 and 14 wk of age in the unilateral castrates than in the intact boars (432 ± 42 vs 245 ± 34%; P<.05). Thus, compensatory hypertrophy occurred within 4 wk of castration. Plasma testosterone was lower for bilateral castrates than for intact animals (.1 ± .8 vs 3.6 ± .9 ng/ml; P<.05) while unilateral castrates (3.8 -+ 1.0 ng/ml) and intact boars did not differ. Plasma estradiol concentrations in bilateral and unilateral castrates were not different from levels found in intact boars (1.8 ± 1.8, 8.8 ± 2.1 and 6.0 ± 1.8 pg/ml, respectively). While mean LH after GnRH was higher in bilateral and unilateral castrates than in intact boars (2,588 ± 147 and 2,693 ± 164 vs 1,928 ± 147 pg/ml; P<.01), castration did not affect the highest LH level after GnRH, time of highest level, magnitude of LH change or rate of LH response during the first 15 rain after GnRH. The rate of change of LH from 0 min to time of maximum LH of the bilateral castrates tended to be greater than that in intact boars (b=202 vs 94; P<.10). These data indicate that the negative feedback of gonadal steroids affects LH secretion.

Isolation Of Lactoferrin And Its Concentration In Sows’ Colostrum And Milk During A 21-Day Lactation, J. I. Elliot, B. Senft, G. Ernhardt, D. Fraser

Nutrition Collection

Levels of lactoferrin, an Fe-binding protein with bacteriostatic properties, were determined in the colostrum and milk of Yorkshire sows during a 21-d lactation. Lactoferrin levels averaged 1,100 to 1,300 μg/ml near the time of farrowing, then declined sharply during the first week of lactation. Concentration of lactoferrin showed considerable variation among sows, but not among teat positions (anterior to posterior). A method for isolating high purity swine lactoferrin is described.

Molecular Genetic Characterization Of The Rd-114 Gene Family Of Endogenous Feline Retroviral Sequences, Roger H. Reeves, Stephen J. O'Brien

Biology Faculty Articles

RD-114 is a replication-competent, xenotropic retrovirus which is homologous to a family of moderately repetitive DNA sequences present at ca. 20 copies in the normal cellular genome of domestic cats. To examine the extent and character of genomic divergence of the RD-114 gene family as well as to assess their positional association within the cat genome, we have prepared a series of molecular clones of endogenous RD-114 DNA segments from a genomic library of cat cellular DNA. Their restriction endonuclease maps were compared with each other as well as to that of the prototype-inducible RD-114 which was molecularly cloned from …

Body Size And Food Size In Freshwater Zooplankton, Kenneth Bogdan, John Gilbert

Dartmouth Scholarship

We used double-label liquid scintilation techniques to measure the efficiencies with which eight different sized zooplankton species ingested four celtypes relative to a standard celtype(Chlamydomonas). Efficiency ratios (ERs:clearancerateonceltypeX . clearancerateonChlam- ydomonas) on the three ultraplankton (<5 Iam in diameter) cels (a coccoid bacterium and the algae Synechococcus and Nannochloris) varied greatly among zooplankton species but were not correlated with zooplankton bodylength. Variation in ERs on a muchlarger(17x 14 um) algalcel(Cryptomonas)was only partly explained by zooplankton body length.

Demographic Analysis And Microhabitat Relationships Of A Small Mammal Community In Clearings Of The Great Dismal Swamp, Jean Ferguson Stankavich

Biological Sciences Theses & Dissertations

Small mammals were trapped for 14 months on two grids located within a powerline right-of-way in the Great Dismal Swamp National Wildlife Refuge. During 12,354 trap nights, individuals of 10 different species were captured. They included, from highest to lowest density, Reithrodontomys humulis, Ochrotomys nuttalli, Peromyscus leucopus, Blarina brevicauda, Synaptomys cooperi, Microtus pennsylvanicus, Microtus pinetorum, Sigmodon hispidus, Mus musculus and Oryzomys palustris. The demography (densities, reproduction, home range and dispersal) of each species was analyzed when possible. Most of the species were present in relatively low densities, with a number being captured only during the latter months of the study. …
