The Romney Marsh, J A. Mallett
The Romney Marsh, J A. Mallett
Journal of the Department of Agriculture, Western Australia, Series 4
THE Romney Marsh, sometimes known as the Kent, is the most popular of the British longwoel sheep breeds used in Western Australia.
Rams of this breed are widely used for mating with Merino ewes, the crossbred female progeny of the matings being in demand for subsequent mating with Downs-type rams to produce export Iambs.

Malaysian Parasites Xxxv-Xlix, W. W. Macdonald
Malaysian Parasites Xxxv-Xlix, W. W. Macdonald
Harold W. Manter Laboratory of Parasitology: Faculty Publications
This is the third Study of the series from this Institute on the external and internal parasites and the biting insects of the Malaysian region. The earlier two volumes were planned and edited by Dr. J.R. Audy, and on his departure from Malaya in the middle of 1959 Mr. W. W. Macdonald continued the work which had been begun and collated and edited the papers in this present Study.
In the two previous volumes (Study No. 26, 1954 and No. 28, 1957) the emphasis was on the taxonomy of Trombiculid mites. In the present volume the emphasis has changed, and …

Notes On Scottsbluff, Nebraska, Tornadoes, 27 June 1955, Robert G. Beebe
National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials
Some general characteristics of thirteen tornadoes that occurred on the afternoon of June 27, 1955 in Scottsbluff County, Nebraska, are related. Two of these caused widespread attention due to their size and their proximity to the cities of Scottsbluff and Mitchell, Nebraska. These two were photographed extensively by residents near their paths. The experience of two men directly beneath one of the two large tornadoes is related.
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Field Techniques For Sexing And Aging Game Animals, Donald R. Thompson
Nebraska Game and Parks Commission: Publications
The purpose of this booklet is to provide a ready field reference for identification, sexing and aging of common game species. It has purposely been kept in simplified form, presenting only those techniques which can commonly be applied in the field and avoiding those which would require special equipment and skills. Untrained personnel should be given demonstrations of the techniques, and thereafter this reference should serve as a reminder. It is not expected that the reference could successfully be used without such demonstration. Certain of the techniques such as cloaca! examination of waterfowl may require considerable practice by the individual. …

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard
Nebraska Game and Parks Commission: Publications
IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

A List Of Cestode Parasites From California Mammals, Marietta Voge
A List Of Cestode Parasites From California Mammals, Marietta Voge
Harold W. Manter Laboratory of Parasitology: Faculty Publications
This report brings together information on the occurrence and distribution of cestode parasites in California mammals. The original information reported herein, was obtained by students, myself, and other staff members of this university. Although the host-parasite list which follows is far from complete, the dearth of knowledge about the helminth fauna in California seems to justify the publication of relatively few data, in the hope that other workers will be able to use this list as a starting point and add to it.
With few exceptions, the common names of the hosts, as given in the host list, were obtained …
Factors Affecting The California Quail Populations In Uintah County, Utah, R. Lynn Nielson
Factors Affecting The California Quail Populations In Uintah County, Utah, R. Lynn Nielson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The California Quail is native to the coastal and semi-arid regions of California extending north into Oregon. Two subspecies are commonly recognized. the California Quail (Lophortyx californica brunnescens Ridgway), and the Valley Quail (Lophortyx californica californica Shaw). The two forms are very similar in coloration and habits and, for the purpose of this study, no effort is made to distinguish the two.
Life History Of The Utah Sculpin Cottus Bairdi Semiscaber (Cope) In Logan River, Utah, William M. Zarbook
Life History Of The Utah Sculpin Cottus Bairdi Semiscaber (Cope) In Logan River, Utah, William M. Zarbook
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The study of the Utah sculpin in Logan River was based on 801 specimens collected during 1949 to March 1951. Numbers of fish examined for various catagories of the study wares length-frequency, 495; aging by vertebrae, 407; length-weight relationship, 601; and food habits, 275.
Fish were collected by use of an electric shocking machine generating 600 watts and 220 volts. Numbers of fish occurred as high as 150 per tenth mile of stream. Preferred habitats occurred in areas of coarse gravel and small rocks.
Vertebrae dissected from the fish were used in age determination. Length-frequency proved to be a general …
Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent
Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent
Papers in Ornithology
An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …

A Study Of The Geographical And Ecological Distribution Of The Buffy Plains Pocket Mouse (Perognathus Flavescens Flavescens), With Description Of A New Subspecies From Nebraska, Myron H. Swenk
University of Nebraska State Museum: Mammalogy Papers
The Buffy Plains Pocket-mouse (Perognathus flavescens flavescens) is a typical mammal of the Sandhill Region of Nebraska. Its home, like that of other species of pocket-mice, is a series of burrows in the ground, consisting of several entrance holes leading to the main 'burrow, in which is located the nest and the food storage chambers. In the Nebraska sandhills its burrows and nests are commonly placed beneath clumps of Spanish Bayonet or Prickly Pear Cactus, and the entrance holes usually are so distributed as to open from under the plant in all directions.
The writer had hoped to …
A Study Of Subspecific Variation In The Yellow Pocket-Gopher (Geomys Lutescens) In Nebraska, And Of The Geographical And Ecological Distribution Of The Variants, Myron H. Swenk
University of Nebraska State Museum: Mammalogy Papers
The Yellow Pocket-Gopher (Geomys lutescens) was described by Merriam (14) in 1890, as a paler and smaller subspecies of Geomys bursarius, based on "numerous specimens received from the Sand Hills of western Nebraska", and especially upon an adult Cjl type specimen (No. 23595, U. S. N. M.) collected in the sandhills along Birdwood Creek, Lincoln County, Nebraska, May 27, 1889, by A. B. Baker. Although even as late as 1931 Scheffer (17) classified Geomys lutescens as a subspecies of G. bursarius, it is without doubt specifically distinct from G. bursarius. In all of its variations …

A Study Of Local Size Variations In The Prairie Pocket-Gopher (Geomys Bursarius), With Description Of A New Subspecies From Nebraska, Myron H. Swenk
University of Nebraska State Museum: Mammalogy Papers
Beginning in the fall of 1913, the writer has continuously been interested in accumulating accurate body measurements, taken in the flesh, of Nebraska pocket-gophers. As a result quite an assemblage of such data has been secured. In the case of Geomys bursarius, the bulk of these data relates to specimens trapped in the vicinity of Lincoln, Lancaster County, involving to date 48 adult and 38 immature males and 50 adult and 65 immature females. Recently these measurements have been tabulated and compared with such measurements of the species as have been recorded in the literature from other parts of …
A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel
A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel
Master's Theses or Doctor of Nursing Practice
During the past 7 years the Great Plains Region, with its "dust bowl", has been the scene of unparalleled activity in the fields of range management and erosion control. The people of this short grass area are extremely conscious of the need for a sound, practical program of conservation that will revegetate the wasted pasture and cultivated land, which will aid materially in preserving the eroding soil. Many problems have arisen as the program of conserving the soil and the vegetation has progressed.
A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter
A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter
Master's Theses or Doctor of Nursing Practice
This particular study has been restricted to certain mammals in western Kansas, including some on which there is little information, and others which observers would be most likely to notice in everyday life. For several years the writer has been vitally interested in the animal life in Kansas. Therefore, when the need for a study of western Kansas mammals was presented to him in the summer of 1936, the problem of this study was selected. It is hoped that this report will suggest to ecologists, historians, and others, further studies, including reasons for the changes here-in shown. What have been …
A Study Of The Structure Of Hair As A Means Of Mammal Identification, Earl R. Oyer
A Study Of The Structure Of Hair As A Means Of Mammal Identification, Earl R. Oyer
Master's Theses or Doctor of Nursing Practice
The hair of small and medium sized mammals is often found in the stomachs, feces and pellets of predators , for example in the stomachs and feces of coyotes and in the pellets regurgitated by hawks and owls. These pellets produced by hawks and owls and the feces of mammalian predators are the undigested residue of what these animals have eaten. If the hair from these sources can be identified, then much desirable information concerning the food of predators can be obtained. The purpose of this study has been to determine whether or not such identification is possible.
Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd
Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd
Master's Theses or Doctor of Nursing Practice
There has developed a need for a practical means of artificially breaking the rest period and of stimulating the growth of grasses so that sods can be procured early in the fall before freezing weather, brought into the greenhouse, and forced early to make an abundant vegetative growth. This need suggested the study of which this paper is the report, namely to discover whether or not the rest period of native grasses can be broken by treatment with potassium thiocyanate and their growth stimulated by artificial light supplemental to winter daylight.
The Flora Of The Tasco Lake Region, Sheridan County, Kansas, Raymond W. Darland
The Flora Of The Tasco Lake Region, Sheridan County, Kansas, Raymond W. Darland
Master's Theses or Doctor of Nursing Practice
It has been customary in writing theses dealing with taxonomic problems to collect data from an entire county. Having had occasion to collect botanical specimens from the Tasco Lake for work in biology at the Sheridan High School, the wealth of plant life to be found here became apparent. The area ranges from xerophytic forms on the uplands to the hydrophytic forms in the lake and marshes. Many of the latter have never been reported from Western Kansas. Collections in preserving fluid were made of the water forms found and specimens of the landforms were mounted on regulation-sized sheets properly …
Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan
Notes On The Distribution Of Amphibia And Reptilia Of Ellis County, Kansas, Lawrence A. Brennan
Master's Theses or Doctor of Nursing Practice
Comparatively little has been done concerning the listing or recording of the Amphibia and Reptilia of Ellis County, Kansas. What records there are of the species are for the most part unpublished. Early papers dealing with Kansas herpetology are few in number. Little has been done in Ellis and the surrounding counties, so there seems to be a need for such an ecological study as has been carried out in this paper “Notes on the Distribution of Amphibia and Reptilia of Ellis County, Kansas . " The objectives kept in mind in preparing this report have been to attempt to …

A Taxonomical, Morphological And Distributional Study Of The Utah Cyprinidae /|Cby Sheldon Phipps Hayes, Sheldon Phipps Hayes
Theses and Dissertations
The hydrography of Utah may be thought of as being roughly divided into two large general drainage areas--, the Colorado River draining the eastern halt and southern portion ot the state and the Bonneville Drainage encompassing the remaining part of it. Earlier workers have listed eight genera and fourteen species of minnows occuring in Utah. Of these this report includes seven genera and ten species found within the borders of our state.
An Analysis Of The Habitat Distribution Of The Vertebrate Fauna Of A Stream- Bank Association In Western Kansas, Olive Falls
An Analysis Of The Habitat Distribution Of The Vertebrate Fauna Of A Stream- Bank Association In Western Kansas, Olive Falls
Master's Theses or Doctor of Nursing Practice
This present paper is chiefly concerned with the distribution of animals. The environmental and faunal conditions of Western Kansas have not been studied, and they are rapidly changing, due to human occupancy of the region. Therefore, a major object of this report is to put on record information in regard to the present vertebrate animal life in Western Kansas. Profound changes in the native conditions have already been recognized; for example, many animals have become extinct, and others are gradually vanishing. It is in the hope of contributing something of the facts of the status of the species in this …

A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward
A New Method For The Quantitative Determination Of Plankton Hauls, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
Only two methods of estimating the quantity of plankton obtained in a haul of the vertical net are known to me. These two may be called the volumetric and the gravimetric. Both have been used by observers in various parts of the world, but so far as I know have never been comparatively tested in order to ascertain the relative value of results obtained by the two. The experience of the past year has shown some disadvantages in the first method, while the second has certain evident objections which rendered its employment in this case out of the question. In …
