The Breeding Biology Of The Western Tanager (Piranga Ludoviciana), Gary G. Benson Jan 1971

The Breeding Biology Of The Western Tanager (Piranga Ludoviciana), Gary G. Benson

All Master's Theses

In 1969 a two-year study was undertaken in an effort to enlarge our knowledge of the life history of the western tanager (Piranga ludoviciana). Bent (1958) summarizes the literature on the western tanager, and a review of his work clearly shows an almost total absence of detailed information on the species' life history. To obtain this information, observations were conducted from 1 May through 29 July 1969. A few observations were made during the 1968 breeding season.


Once A Day Calf Feeding, R A. Bettenay Jan 1971

Once A Day Calf Feeding, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

Trials at Wokalup Research Station in 1970 proved that calves could be successfully reared with once a day liquid milk feeding, providing a high protein meal was continually available.

This trial was carried out to see if the high protein meal was essential for the success of the once a day feeding system.


Wildlife Hazards From 1080 Baiting, A R. Tomlinson, C. D. Gooding Jan 1971

Wildlife Hazards From 1080 Baiting, A R. Tomlinson, C. D. Gooding

Journal of the Department of Agriculture, Western Australia, Series 4

ONE-SHOT oat baiting with sodium fluoroacetate (1080) is a relatively safe method of trail baiting rabbits.

The hazard to wildlife is small and every effort is made to further reduce the hazard by selective application of the poison.

Journal of the Department of Agriculture, Western Australia, Series 4

A short article outlining methods to control flystrike.


Flystrike Control Programmes, H E. Fels Jan 1971

Flystrike Control Programmes, H E. Fels

Journal of the Department of Agriculture, Western Australia, Series 4

THE various flystrike control methods all avoid susceptible patches of skin on the sheep.

To avoid work—

• choose methods that give the most control for the least effort, and

• combine these methods into a system that works well.


How To Control Flystrike In Sheep, H E. Fels Jan 1971

How To Control Flystrike In Sheep, H E. Fels

Journal of the Department of Agriculture, Western Australia, Series 4

FLYSTRIKE affects incomes and efficiency because a large part of the work done on sheep farms is to prevent or treat it, and because it kills sheep and reduces the amount and quality of production.


Prevent Worms In Cattle, G C De Chaneet Jan 1971

Prevent Worms In Cattle, G C De Chaneet

Journal of the Department of Agriculture, Western Australia, Series 4

PARASITIC gastro enteritis, caused by roundworms, is a common cause of economic loss in calves, yearlings and occasionally cows in south-western Australia. Losses could be prevented if stock owners realised the full effects of these parasites, and understood the causes of worm infestation.


Bacula Of Some Neotropical Bats, Randall E. Brown, Hugh H. Genoways, J. Knox Jones Jr. Jan 1971

Bacula Of Some Neotropical Bats, Randall E. Brown, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Neotropical bats representing 56 species of five families were examined for presence or absence of a baculum. Members of the families Noctilionidae and Phyllostomatidae (sensu lato) have no os penis, but the bone was found in all species studied of Emballonuridae, Natalidae, and Vespertilionidae. The bacula of seven emballonurids, one natalid, and seven vespertilionids are briefly described and figured.


Observations On Sound Production In The Anatidae, Paul A. Johnsgard Jan 1971

Observations On Sound Production In The Anatidae, Paul A. Johnsgard

Paul Johnsgard Collection

It has been known for a long time that, among non-passerine birds, the Anatidae are remarkable for the diversity of specializations in the trachea and syrinx, associated with sound production. It has also been recognised that these variations have taxonomic significance (Heinroth 1911; Johnsgard 1961), but virtually no attempts have been made to correlate the complex tracheal structures with the sounds produced. Yet the group offers many fascinating problems such as the adaptive significance of the looping of the trachea, either outside the body cavity as in the Magpie Goose Anseranas semipalmata, or inside the sternum as in the …


Morphology Of The Spores Of Myxosoma Cerebralis (Hofer, 1903) And M. Cartilaginis (Hoffman, Putz, And Dunbar, 1965)*, Glenn L. Hoffman, Jiří Lom Jan 1971

Morphology Of The Spores Of Myxosoma Cerebralis (Hofer, 1903) And M. Cartilaginis (Hoffman, Putz, And Dunbar, 1965)*, Glenn L. Hoffman, Jiří Lom

United States Fish and Wildlife Service: Publications

The spore of Myxosoma cerebralis is redescribed and compared with that of a close relative, M. cartilaginis. M. cerebralis is smaller, with greater variability in size and shape. It possesses a mucous envelope whereas M. cartilaginis does not. The surface architecture of M. cerebralis, as seen with the scanning electron microscope, differs in possessing a conspicuous circumsutural groove, prominent polar filament pores, and a mucous envelope.


Some Biological Aspects Of Lizard Eimerians, With A Description Of Eimeria Poinsettis N. Sp. From Sceloporus Poinsetti, David A, Colwell Jan 1971

Some Biological Aspects Of Lizard Eimerians, With A Description Of Eimeria Poinsettis N. Sp. From Sceloporus Poinsetti, David A, Colwell

All Master's Theses

A previously described eimerian, Eimeria sceloporis, from the northwestern fence lizard, Sceloporus occidentalis occidentalis, was observed for oocyst production, incidence and intensity of infection in both juvenile and adult lizards. In order to test the species specificity of Eimeria ahtanumensis, an attempted transmission was made to Sceloporus poinsetti, Sceloporus jarrovi, Sceloporus undulatus and Sceloporus occidentalis. During the winter of 1970-1971 fecal samples were collected from Sceloporus poinsetti to determine possible coccidial infections. The lizards were collected in September of 1970 in Hidulgo County, New Mexico and the ensuing investigation showed that nine of the thirteen adults were passing an intestinal …

Nutrition Studies Of The Brindled Madtom, Noturus Miurus Jordan, Based On Stomach Content Analysis, Randall Stephen Madding

Masters Theses

Brindled madtoms and small channel catfish (140 mm or less) were examined to determine their food habits and the possibility of competition for food organisms between the two species when collected from the same area.

Two hundred twenty-three brindled madtoms were collected from Polecat Creek (study area I) 3 miles southwest of Ashmore, Coles County, Illinois. The study in Polecat Creek was conducted from July 10, 1967 to June 5, 1968, collections being made approximately every month. Two hundred forty-five brindled madtoms and 140 channel catfish were collected from the Embarras River (study area II) 2 miles south of Charleston, …


Reproductive Cycle Of The Male Snapping Turtle, Chelydra Serpentina Serpentina (Linné), Harold Edward Benny Jan 1971

Reproductive Cycle Of The Male Snapping Turtle, Chelydra Serpentina Serpentina (Linné), Harold Edward Benny

Masters Theses

Thirty-seven male Chelydra s. serpentina were collected from Illinois, Louisiana, Mississippi, Tennessee, and Wisconsin during months of activity from May, 1969 to June 1971. Carapace length for each specimen was measured, and testes and epididymides were dissected out, weighed, measured, fixed, and preserved in Baker's neutral formalin within seven days of capture. Paraffin sections were stained with hematoxylin and eosin. Frozen sections were stained with Sudan IV.

The spermatogenic cycle was similar to those of other Chelonians and reptiles exhibiting post-nuptial spermatogenesis. In Illinois spermatocytogenesis begins in late March or early April. Meiosis is evident throughout May and early June. …


Trap Manifested Behavior Trap Reflected Density Trap Reflected Distribution And Foods Consumed By Raccoons (Procyon Lotor L.) In Two Natural Areas Of Virginia, Elton L. Winslow Jan 1971

Trap Manifested Behavior Trap Reflected Density Trap Reflected Distribution And Foods Consumed By Raccoons (Procyon Lotor L.) In Two Natural Areas Of Virginia, Elton L. Winslow

Biological Sciences Theses & Dissertations

A study was undertaken comparing populations of raccoons (Procyon lotor L.) in two natural areas of Virginia, one in the Piedmont physiographic province at Montpelier and the other in the coastal plain at Newport News. Comparisons were made with respect to differences in: (1) capture and recapture success, (2) relative trap reflected density, (3) trap reflected distribution with respect to aquatic habitat, and (4) in food consumption. Comparison of capture data indicated that capture success per 100 trap nights was much higher at Newport News (1.58) than at Montpelier (.76). However a similar comparison of recapture success per …

A Comparative Study Of The Head And Thoracic Osteology And Myology Of The Skinks Eumeces Gilberti Van Denburgh And Eumeces Skiltonianus (Baird And Girard), David F. Nash, Wilmer W. Tanner Dec 1970

A Comparative Study Of The Head And Thoracic Osteology And Myology Of The Skinks Eumeces Gilberti Van Denburgh And Eumeces Skiltonianus (Baird And Girard), David F. Nash, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The differences observed from the osteology and myology are few and subtle.

Neither species is consistent in having all of the anatomical characters equal. E. skiltonianus, however, is more variable than gilberti. This species: 1. exhibits a wider range of variation in the number of slips of the intermandibularis anterior; 2. has two distinct bundles of the depressor mandibularis; and 3. has variation in the anterior suture pattern of the frontal, nasal, prefrontal and maxilla elements. E. gilberti on the other hand has: 1. only one distinct bundle of the depressor mandibularis; 2. a frequent reduction of the relative size …

Additional Notes An Some Mammals From Eastern Nebraska, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Field studies concerned primarily with distribution of the short-tailed shrew, Blarina brevicauda, in eastern Nebraska have resulted in noteworthy records of several other species of small mammals. These field studies, which were supported by a grant from the Kansas Academy of Science, entailed extensive trapping of prairie habitats in Cass County, approximately 15 miles west of the Missouri River. In addition to the species discussed below, specimens of Reithrodontomys megalotis, Peromyscus maniculatus, P. leucopus, and Mus musculus were obtained at several localities. All catalogue numbers in the following accounts refer to specimens deposited in the Museum of Natural …

Roasted Soybeans For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Richard Berns Nov 1970

Roasted Soybeans For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Richard Berns

South Dakota Swine Field Day Proceedings and Research Reports, 1970

Soybeans contain about 18% fat. In the past it has been economical to process the soybeans into soybean meal. Soybean meal is the major protein supplement fed to swine. The recent development of new equipment to cook soybeans on the farm has resulted in a renewed interest in the use of cooked soybeans in swine rations. The objectives of the study reported here were to compare the performance of pigs fed whole soybean meal and to study the effects of whole soybeans on the carcasses produced.
