Twenty-One Years Of Say's Phoebes, Doris Gates Mar 1980

Twenty-One Years Of Say's Phoebes, Doris Gates

Nebraska Bird Review

Mr. and Mrs. Carl Lindeken live 10.5 miles northeast of Chadron, Nebraska, in a home with a big picture window over the kitchen sink, a window that faces the Sheridan Gates, a formation which is in Sheridan County across the Dawes County line. Outside the window is a small platform on which Say's Phoebes have nested for many years.

The first year the Lindekens were aware of Say's Phoebes was in 1958 when a pair nested in the garage, a building which is attached to the house. The birds were "messy" but they were allowed to remain through the summer. …


Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service Mar 1980

Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service

Publications (WR)

The U.S. Water and Power Resources Service is considering reregulating Lake Mohave water levels to increase the net power benefit from Hoover Dam. Reregulation will not increase the generation capacity of the Hoover powerplant but it will enable the plant operation to be increased when the energy has greater monetary value. Energy generated at different times of the year has different market value, the highest being in January-March and July- September. By generating more power during these periods more net monetary benefit can be derived from Hoover Dam. The total volume of water released from Hoover Dam over an annual …

Observations Of Late Fall Migratory Sandhill Cranes, Platte River, Nebraska, John G. Aronson Mar 1980

Observations Of Late Fall Migratory Sandhill Cranes, Platte River, Nebraska, John G. Aronson

Nebraska Bird Review

Observations of migratory Sandhill Cranes (Grus canadensis) were made on the Platte River near Kearney, Nebraska. On 26 November 1978, night roosting in the Platte River occurred on thin ice (less than 2 cm) in open areas which were protected by riparian vegetation from cold north winds (35-40 km/hr-NNW, -10°C). Roosting Cranes were spaced very closely (less than 0.5 m) during evening and early morning hours, with increased spacing (about 1.0 m) occurring during late morning. A diagram of the roost area was prepared. The roost was located near the northern river bank in a river stretch characterized …

A Ground Dove At Desoto Nwr, Loren Padelford, Babs Padelford

Nebraska Bird Review

A Ground Dove was sighted at DeSoto National Wildlife Refuge on 18 November 1979, for about ten minutes around 11 AM, in the hedgerows opposite the entrance to the nature trail, south of the swimming beach.

It was a small dove, only slightly longer but chunkier than Tree Sparrows sitting in the same small tree. There was gray scalloping on the head and breast, the eye was dark, the beak light colored at the base, with the rest appearing dark. The wing was grayish with black speckling from shoulder to tip. We noticed a short tail when the bird was …

Notes On The Natural History Of Bats From Badlands National Monument, South Dakota, John P. Farney, J. Knox Jones Jr. Mar 1980

Notes On The Natural History Of Bats From Badlands National Monument, South Dakota, John P. Farney, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Little has been published on the mammalian fauna of Badlands National Monument, a unique ecological area that encompasses parts of Jackson and Pennington counties in South Dakota. By way of example, although five species of bats are herein recorded from the Monument, only one has been reported previously - see Jones and Choate (1978), who listed two specimens of Myotis thysanodes pahasapensis from the Cliff Shelf area. Jones and Genoways (1976b), however, did report several other species from badland areas not far distant from the boundary of the Monument.

In 1970, under sponsorship of the Badlands Natural History Association and …

Genetic And Economic Implications Of Fetal Effects On The Dam, L. Dale Van Vleck, L. P. Johnson Jan 1980

Genetic And Economic Implications Of Fetal Effects On The Dam, L. Dale Van Vleck, L. P. Johnson

Department of Animal Science: Faculty Publications

The genetic model for fetal effect on production of the dam is described, and studies on genetic and economic implications are reviewed. The effect on production from the sire of the cow has 1.58 to 3.02 times as much economic value as the effect from the sire of the fetus. The use of mate records in evaluating a sire in addition to daughter records could increase economic gain from selection by 1 to 2% depending on the variation from sire of fetus. Mate records alone do not appear valuable for sire selection. About 1% of the variation in milk yield …


A Post-Impoundment Investigation Of The Beech Fork Drainage Basin, Twelvepole Creek, Wayne And Cabell Counties, West Virginia, Donald Borda Jan 1980

A Post-Impoundment Investigation Of The Beech Fork Drainage Basin, Twelvepole Creek, Wayne And Cabell Counties, West Virginia, Donald Borda

Theses, Dissertations and Capstones

Fish populations were collected at six stations by means of electrofishing to determine the composition after impoundment. A total of 748 fishes weighing about 9 pounds (4 kg) were collected. Seven families representing 31 species were collected and categorized as game, forage and rough fishes. Game fishes made up 9.1 percent of the total number and 22.3 percent of the total weight; forage fishes 83.0 percent by number and 29.7 percent by weight. The average standing crop was 15 pounds per acre.

Benthic invertebrates were collected at six stations by means of a bottom dredge. A total of 1535 specimens …

Nesting Ecology Of The Red-Winged Blackbird In North Central Minnesota, Daniel W. Moulton Jan 1980

Nesting Ecology Of The Red-Winged Blackbird In North Central Minnesota, Daniel W. Moulton

Journal of the Minnesota Academy of Science

Reproductive success of a Red-winged Blackbird population nesting in marsh-like habitat In north central Minnesota was estimated. Territorial defense by males began in late April, and nest initiation occurred from mid-May through about mid-July. Nest-starts appeared to be divided into two categories: initial attempts which occurred in late May with a high degree of synchrony, and renesting attempts which occurred from about June 4-July 8, The nesting season lasted only about two months. A minimum of 20 percent of marked females renested on the study area, and others may have renested elsewhere. Three of the six females that renested switched …


Age Study Of Minnesota Red Fox Using Cementum Annulae Counts And Tooth X-Rays, Dennis E. Simon, Merrill J. Frydendall Jan 1980

Age Study Of Minnesota Red Fox Using Cementum Annulae Counts And Tooth X-Rays, Dennis E. Simon, Merrill J. Frydendall

Journal of the Minnesota Academy of Science

A prerequisite to the proper management of an animal species is understanding of its population dynamics. Attempting this, the age structure of 297 red fox trapped or shot in southern Minnesota was investigated, using the techniques of tooth sectioning and x-ray. Results from two seasons (1977 and 1978) were similar, with 76.8 percent of the harvested population being juveniles (78.4 percent, 1977 and 74.6 percent, 1978), whereas only 0 .6 percent of the total were in the 4½ year old class. The percentage of juveniles corresponds closely to the numbers predicted by a Department of Natural Resources model developed by …


The Malaysian Fishing Gears And Methods, Mohamed Ibrahim Bin Haji Mohamed Jan 1980

The Malaysian Fishing Gears And Methods, Mohamed Ibrahim Bin Haji Mohamed

Marine Affairs Theses and Major Papers

There are more than 40 types of fishing gears operated in Malaysia. These gears are classified locally into 11 gear groups based on their principles of operation. These gears have never been fully documented. This investigation attempts to document all the commercially important fishing gears in the country, the technical specifications, methods of operation, identify spacial differences in gears, operation and review the share/lay system operated in the industry.


The Feasibility Of Increased Utilization Of The Georges Bank Herring Stock, Carder Starr Jan 1980

The Feasibility Of Increased Utilization Of The Georges Bank Herring Stock, Carder Starr

Marine Affairs Theses and Major Papers

The United States has embarked upon a new era of commercial fisheries management and development with the enactment of the Fishery Conservation and Management Act of 1976 (FCMA). The primary objectives of the FCMA are "to take immediate action to conserve and manage the fishery resources found off the coasts of the U.S." and "to encourage the development of fisheries which are currently underutilized...by the U.S. fishing industry...." One of these underutilized stocks is the Georges Bank herring stock. This study hopes to show that the operation of a fish-processing vessel can be a feasible enterprise with good returns to …


The Impact Of Extended Jurisdiction To 200 Nautical Miles On The Development And Management Of Fisheries In Western Samoa, Fili Suafoa Jan 1980

The Impact Of Extended Jurisdiction To 200 Nautical Miles On The Development And Management Of Fisheries In Western Samoa, Fili Suafoa

Marine Affairs Theses and Major Papers

The consequences of the inevitable acceptance of extended jurisdiction and its impact on the development and management of fisheries in Western Samoa are considered within the framework of the principles outlined at the United Nations Third Conference of the Law of the Sea - Revised Informal Composite Negotiating Text for the Eighth Session 1979. It is pointed out that with the passage of the 200-mile exclusive economic zone, Western Samoa not only has the opportunity to benefit from the harvesting of fish under its jurisdiction, but also must accept the responsibility of ensuring that the resource is rationally managed, and …


The Feasibility Of Processing Fish Aboard The F/V Friesland, Thomas Dykstra Jan 1980

The Feasibility Of Processing Fish Aboard The F/V Friesland, Thomas Dykstra

Marine Affairs Theses and Major Papers

Many social, economic and regulatory changes have been occurring in the New England fishing industry over the past few years. These changes demand responses from the individual industry participants. The purpose of this paper is to look at the feasibility of processing onboard the F/V Friesland, as an individual response, in an effort to increase the ex-vessel price of fish resulting in the maintenance of a gross stock and a life style. The F/V Friesland, built in 1978, is an 87 foot stern trawler which participates in the mixed species groundfshery of New England out of the port of Pt. …


Fisheries Report No 39 - The Wildlife Of The Proposed Toolonga Nature Reserve, Shark Bay Shire, Western Australia, A. A. Burbidge, P. J. Fuller, K. Cashin Jan 1980

Fisheries Report No 39 - The Wildlife Of The Proposed Toolonga Nature Reserve, Shark Bay Shire, Western Australia, A. A. Burbidge, P. J. Fuller, K. Cashin

Fisheries Research Reports

Following a Cabinet endorsed recommendation by the Environmental Protection Authority in 1975, an area of vacant Crown Zand (the Toolonga Area) was examined during April and September, 1978.

The geology, soils and vegetation of the area are described and annotated lists of mammals, birds, amphibians and reptiles are presented. A small part of the area lies in the South West Botanical Province (Irwin District) but most is in the Eremaean Botanical Province (Carnarvon District). The vertebrate fauna is a mixture of south-western, Shark Bay and arid zone species, but the last predominate.

The Toolonga Area provides an opportunity to protect …


Amputation Of Vibrissae In Show Dogs, Thomas E. Mcgill Jan 1980

Amputation Of Vibrissae In Show Dogs, Thomas E. Mcgill

Veterinary Science and Medicine Collection

Dogs of many different breeds competing in the show-ring are routinely subjected to amputation of the vibrissae, organs that are commonly and incorrectly called "whiskers." This procedure is thought to give the animal's head a cleaner look, which in turn supposedly increases its chances of winning. There are several tricks involved in "whisker trimming" since the animals can retract each vibrissae at least one-quarter inch. Furthermore, they often object strenuously to the operation.


Stress: What Is It And How Can It Be Quantified?, T. H. Friend Jan 1980

Stress: What Is It And How Can It Be Quantified?, T. H. Friend

Sentience Collection

An animal may be considered to be in a state of stress if abnormal behavior or extreme adjustments in its behavior or physiology are necessary in order to cope with adverse aspects of its environment. Methods used to determine if an animal is stressed can be either behavioral or physiological. Behavioral methods may be highly erroneous due to their subjective nature since alterations in behavior do not necessarily prove that an animal is stressed. There is no single measure of stress that can be used in all situations at this time. Every measure must be critically evaluated to ensure that …


Nongame Birds Of The Rocky Mountain Spruce- Fir Forests And Their Management, Kimberly G. Smith Jan 1980

Nongame Birds Of The Rocky Mountain Spruce- Fir Forests And Their Management, Kimberly G. Smith

T.W. "Doc" Daniel Experimental Forest

Spruce-fir forests in the Rocky Mountains consist mainly of Engelmann spruce and subalpine fir. The breeding avifaunas in these forests show remarkable consistency in composition along a latitudinal gradient from Montana to Arizona and New Mexico, and with avian communities in the Hudsonian life zone in Washington, Oregon, and California. Woodpeckers, corvids, and seed-eating finches are the most common components. Only the Golden Eagle and a few other raptors are threatened or endangered. Few species winter in these high mountain forests. The distribution of many species is controlled primarily by the vegetation physiognomy, a variable under the control of the …


Population Regulation In Wolves, Jane M. Packard, L. David Mech Jan 1980

Population Regulation In Wolves, Jane M. Packard, L. David Mech

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

The possibility of social regulation of wolf populations has been discussed in the literature for several years. Some of the first ecological studies of wolves indicated that their populations did not increase as rapidly as was theoretically possible, and that they reached a saturation point apparently not set by food. Subsequent captive studies demonstrated the existence of social mechanisms possibly capable of regulating population growth. However, the importance of these factors in wild populations has not been established. This paper has four objectives: (1) to evaluate the existing concept of "intrinsic limitation," (2) to propose that wolf population dynamics may …

Varieties Of Cheese, T A. Morris Jan 1980

Varieties Of Cheese, T A. Morris

Bulletins 4000 -

While Cheddar cheese is by far the main type as far as English speaking countries are concerned, it is only one of a large number of varieties of cheese which are becoming more universal in production and consumption. In other than English speaking countries Cheddar cheese is almost unknown and yet the consumption of cheese in some of these countries is very much greater. The naming of cheese types has usually been a result of the use of the name of the place where the cheese was first made. Thus cheeses of similar type but produced in a different locality …


The Relationship Of Food Conversion Efficiency And Growth Potential In Juvenile Mosquitofish, Gambusia Affinis, Joseph J. Cech Jr., Michael J. Massingill, Wayne A. Wurtsbaugh Jan 1980

The Relationship Of Food Conversion Efficiency And Growth Potential In Juvenile Mosquitofish, Gambusia Affinis, Joseph J. Cech Jr., Michael J. Massingill, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

New information concerning respiratory metabolic rates of juvenile mosquitofish (i = 915 mg 02 kg-1 h-1 at 20° C) was applied to existing data on mosquitofish respiration and combined with findings on growth and food consumption rates to determine percentages of net ingested energy used for growth and respiration over a 10- 35° C temperature range. The energy percentage used by mosquitofish for respiration was minimized at 25-30° C while that used for growth (= food conversion efficiency) was maximized at the same temperature. A calculated growth potential index, derived from an overall energy balance equation, was also maximized at …
