Fisheries Research Report No. 112 - Final Report, Frdc Project 94/075: Enhancement Of Yabby Production From Western Australian Farm Dams, Fisheries Western Australia, Fisheries Research And Development Corporation

Fisheries Research Reports

Farmers receive higher prices per kilo for large yabbies. Yabby farmers have reported that the majority of yabbies trapped from farm dams are below market size (< 30 g) and therefore of no economic value. In addition, farmers also report that while dams produce large yabbies when first harvested, after a number of years the proportion of large animals gradually decreases.

To identify why yabbies in farm dams stunted and how farmers could increase the size of small yabbies the project had three main experimental areas.

Research station experiments: A field research station consisting of 25 ponds was constructed for running replicated, randomised and reproducible experiments, with controls, in an environment that simulated farm dams. In addition, these ponds were large enough to provide an adequate sample number of yabbies at realistic industry stocking …

Grassland Birds And Habitat Structure In Sandhills Prairie Managed Using Cattle Or Bison Plus Fire, Randall Griebel, Stephen L. Winter, Allen Steuter

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Grassland birds are known to respond to specific changes in habitat structure, such as plant height and density. However, the response of grassland bird communities to management induced changes in the regional habitat mosaic are less well understood. Grazing by ungulates and fire regimes play an important role in defining the habitat mosaic in the Great Plains. We provide information on bird abundance, distribution, and habitat structure from similar sandhill prairie landscapes managed traditionally with grazing by cattle (Bos taurus) and by a dynamic bison (Bos bison)-plus-fire regime. Although the two management regimes are dissimilar, only …

Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan

Biological Sciences Theses & Dissertations

Loblolly pine plantations were examined at different ages to identify small mammal community attributes in relation to the succession of the plant community. Forest floor and understory plant communities were characterized. Small mammals were collected by Fitch (live) traps and pitfall traps in four age classes during five seasons of study. Fitch live traps and pitfall traps were used in conjunction with one another to obtain the most accurate depiction of the small mammal community. Fitch traps accounted for 65 % of small mammal captures and 7 of 9 species captured. Small mammal abundance and biomass declined with increasing stand …

Habituation, Novelty Response, And Object Differentiation In The Weakly Electric Fish, Brachyhypopomus Pinnacaudatus, Gregory J. Scott

Dissertations and Theses

Weakly electric fish use a combination of active electrolocation and passive mechanosensory receptors for object detection and analysis. When tested with repeated presentations of the same moving object, Brachyhypopomus pinnacaudatus showed a gradual habituation of its electric organ pacemaker acceleration response (novelty response) that was unaltered by changes in the replacement electric organ discharge (S1). When tested with objects of differing velocities, the novelty response of the fish was proportional to the change in velocity of object. The responses of fish to objects that presented different mechanosensory profiles, but equal electrosensory profiles, suggest that the fish used the electrosensory system …

A Half-Century Of Winter Bird Surveys At Lincoln And Scottsbluff, Nebraska, Paul A. Johnsgard

Papers in Ornithology

Since 1900, the National Audubon Society has sponsored annual "Christmas bird counts" during the two-week period encompassing Christmas; and as a result, long-term data on winter bird populations have accumulated, especially for some locations. The first two such counts in Nebraska were made in 1909 and in 1912 in Lincoln. Beginning in 1947 and continuing to the present, an unbroken series of counts were made in Lincoln, usually by members of the Uni¬versity Place Bird Club, the Audubon Naturalist's Club, or the Wachiska chapter of the National Audubon Society. For Scottsbluff, an unbroken set of counts extends from 1949 to …

Evolution And Animal Welfare, Marian Stamp Dawkins

Assessment of Animal Welfare Collection

Animal welfare is a topic often thought to reside outside mainstream biology. The complexity of the methods used to assess welfare (such as health, physiology, immunological state, and behavior) require an understanding of a wide range of biological phenomena. Furthermore, the "welfare" of an animal provides a framework in which a diversity of its responses can be understood as fitness-enhancing mechanisms. Different methods for assessing animal welfare are discussed, with particular emphasis on the role of an animal's own choices and reinforcement mechanisms. No part of biology is as yet able to explain consciousness, but by confronting the possibility that …

Whey Protein Edible Film Structures Determined By Atomic Force Microscope, L.E. Lent, L. S. Vanasupa, P. S. Tong

Dairy Science

Atomic force microscopy was used to study edible films produced from whey proteins. The films were imaged under ambient conditions with no special sample preparation. Low resolution imaging of areas from 10 μm to 150 μm on a side was performed in the contact mode. Higher resolution scans of 350 nm to 2,700 nm required use of the noncontact imaging mode. Features about the same size as the primary protein in whey, beta-lactoglobulin (7 nm), were identified in the film samples. Molecular aggregates in the range of 1 μm, reported in other studies using transmission electron microscopy of whey protein …

1998 Midwinter Eagle Survey For Nebraska Including Summary Tables For The 1980-1998 Period From The Nebraska Game And Parks Commission, John J. Dinan

Nebraska Bird Review

Mild temperatures were prevalent in the weeks prior to this year's survey; however, temperatures cold enough to form a thin layer of ice on some reservoirs and lakes occurred between aerial surveys. Three of the aerial surveys were conducted on the 6th and 7th of January and one was conducted on the 13th. The survey route that includes the Platte River from Kearney to Plattsmouth and the Loup River was not surveyed this year because of persistent foggy conditions.

Temperatures recorded during the 1998 survey were variable, ranging from 5 to 40 degrees F. The Niobrara River was 50 to …

Bald Eagle Counts At Two Facilities Owned And Operated By The Central Nebraska Public Power And Irrigation District, Mark M. Peyton, Rodger Knaggs

Nebraska Bird Review

Since 1988 the Central Nebraska Public Power and Irrigation District (Central) has provided, free to the public, a bald eagle viewing facility in its Johnson #2 Hydroelectric Plant south of Lexington, Dawson County, and since 1990 a facility near the outlet of the Kingsley Hydroelectric Plant at Lake Ogallala in Keith County.

Central provides binoculars and viewing scopes at both locations as well as personnel to answer questions and provide assistance. These individuals also conducted daily eagle surveys at the facilities.

Summer Field Report, June-July, 1998, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

First, some housekeeping is in order. . . . You will also notice the new order of species (AGAIN!!), reflecting the latest American Ornithologists' Union Checklist, published this spring. The most noticeable change concerns the placement of shrikes and vireos between flycatchers and corvids; but the order of species within some genera also differs, especially among the waterfowl, where, for instance, swans now follow the geese.

And now let's turn to the birds! As in most summers, many species went about their business in routine fashion, hence the notation "Routine Reports" for many.

We encourage observers to note and to …

Book Review: Baby Bird Portraits By George Miksch Sutton: Watercoiors In The Field Museum By Johnsgard, P. A. (1998), John J. Janovy Jr.

Nebraska Bird Review

George M. Sutton's baby bird portraits are his most captivating works. The subjects are isolated against a stark, raw-paper background, and they stare out at the viewer with eyes typically naive but alert. Sutton's artistic mastery of the foot is integral to the underlying biology in these pictures: sturdy and sure against the table for a ruffed grouse, curled inward and near useless for a gallinule on dry land, and almost casually clutching a twig, the hallux resting loosely, for a newly fledged grosbeak. The match between these pictures and Paul Johnsgard's text is perfect. In his first two paragraphs, …

The Mortenson Ranch: Cattle And Trees At Home On The Range. A Restoration Guidebook, Susan E. Boettcher, W. Carter Johnson, Scott Kronberg, F. Robert Gartner, Clarence Todd, Jeff Mortenson, Scott Fausti

Natural Resource Management Faculty Publications

Early agriculture on western rangeland met with little success and resulted in serious consequences including soil erosion, loss of native woodlands and wildlife, and economic ruin. The Mortenson family in Stanley County, South Dakota, has been engaged in restoring degraded rangeland on their ranch for more than 50 years. Their primary goal has been to return the land to its condition prior to white settlement while maintaining a profitable cattle ranching operation. In recent years the ranch has served as a model of successful ranching based on a conservation ethic. This guidebook summarizes the restoration techniques and grazing regime used …

Bats Of The Antillean Island Of Grenada: A New Zoogeographic Perspective, Hugh H. Genoways, Carleton J. Phillips, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

The island of Grenada is the southernmost of the Lesser Antilles, lying 130 km north of Trinidad and 135 km north of the Venezuelan mainland. It measures 34 km north to south and 19 km east to west and has an area of 312 square km. Grenada and the Grenadines northward to Bequia stand on the large submarine Grenada Bank. At 183 m depth, the bank is 179 km long. The Grenadines cover the bank to its northern end, but the bank extends for 39 km south of Grenada with no islands. During the last Ice Age, Grenada and the …

The Effect Of Calf Morbidity On Feedlot Performance And Profitability, Jessica Gentry

Masters Theses & Specialist Projects

Two "Value-Added Calf (VAC) Programs were evaluated relative to feedlot performance and profitability. Two hundred seventy-three head of feeder calves were included in this study. Ninety-five Certified: Preconditioned for Health (CPH), ninety KCA Gold Tag and eighty-eight "Sale Barn" cattle were fed at Horton's Research Feedyard in Fort Lupton, Colorado. No background information regarding the health status of the Sale Barn cattle was known. Cattle were purchased in December 1997 and were entered in the Rocky Mountain Ranch-to-Rail program on January 6, 1998. The cattle were checked daily for illness and taken to a hospital pen for treatment if symptoms …

Radiocarbon From Nuclear Testing Applied To Age Validation Of Black Drum, Pogonias Cromis, Steven E. Campana, Cynthia M. Jones

OES Faculty Publications

Radiocarbon ((14)C) in the world's oceans increased sharply between 1950 and 1970 as a result of the atmospheric testing of nuclear weapons. Through comparison with the (14)C time series reconstructed from atmospheric measurements and marine carbonates, Kalish, in 1993, used the (14)C concentration measured in fish otolith cores as a means of confirming the annulus-based age estimates for some South Pacific fish species. Here we report the pre-and postbomb (14)C chronology of North Atlantic adult black drum (Pogonias cronis), assumed to be between 15 and 42 yr of age on the basis of otolith annulus counts. According to …

Review Of A Guide To The Nests, Eggs, And Nestlings Of North American Birds, Paul A. Johnsgard

Papers in Ornithology

In 1978, during a visit to England, I purchased a copy of the first edition of this book, then called a field guide. It was written by Colin Harrison, published by Collins, and produced in standard field guide size. It never was effectively distributed in North America, which was unfortunate, because it was far better than the guide to bird nests by Hal Harrison in the well-known Peterson field guide series. Not only did it illustrate the eggs of about 550 species, in color and life size, but it also offered nestling paintings of nearly 150 species, plus numerous line …

Gap Analysis Of The Vegetation Of The Intermountain Semi-Desert Ecoregion, David M. Stoms, Frank W. Davis, Kenneth L. Driese, Kelly M. Cassidy, Michael P. Murray
