Cedar Creek Natural History Area, 1963, William H. Marshall Jan 1964

Cedar Creek Natural History Area, 1963, William H. Marshall

Journal of the Minnesota Academy of Science

This paper is to inform members of the Minnesota Academy of Science and other citizens of the state as to the present status of the Cedar Creek Natural History Area. It is necessary for several reasons: first, as an opportunity to fully acquaint you with the contributions of the late Dr. Arthur N. Wilcox and Dean T. H. Fenske, and second, because we are entering a new phase in the evolution of the project.


Populations Of Peritrichs On The Pond Snail, Physa Gyrina Say, Peter Moyle Jan 1964

Populations Of Peritrichs On The Pond Snail, Physa Gyrina Say, Peter Moyle

Journal of the Minnesota Academy of Science

There are many obscure niches in a, pond that make fascinating ecological studies. The shell of a pond snail such as Physa gyrina Say, is one of these. In this study alone, 18 species of attached animals and plants were found growing on P; gyrina shells. About half of these species occurred on the shells in large numbers and completed a large part of their life cycle there. On P. gyrina, the most abundant animals included three species of protowans and a tendipedid larva. The protozoan species, Epistylus niagarae Stokes, Opercularia ramosa Stokes, and V orticella campanula Ehrenberg all belong …


The American Eagles And Their Economic Status, E. R. Kalmbach, Ralph H. Imler, Lee W. Arnold Jan 1964

The American Eagles And Their Economic Status, E. R. Kalmbach, Ralph H. Imler, Lee W. Arnold

United States Fish and Wildlife Service: Publications

For centuries eagles have captured the fancy of man the world over. Because of its extensive range in the northern hemisphere, the golden eagle is the most widely known of this group of birds. Its use in falconry was the sport of kings. The frequency of its appearance in royal coats of arms indicated its importance. It is the national emblem of Germany and Mexico.

In North America the bald eagle as well as the golden eagle represents this group of powerful birds of prey. The bald eagle is strictly an American species, and the founders of the United States …


Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons Jan 1964

Weaning Lambs Under Pastoral Conditions, H Suijdendorp, L. Parsons

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

IN the summer rainfall region of the pastoral areas lambs are too often born too late to ensure their survival.

In good seasons with a fair measure of winter rain more late lambs will survive, but losses are still serious. The only solution to this problem is to make sure lambs drop in May-June.

But the presence of late and often unmarked lambs at mating time is a disturbing influence, which makes it hard to advance the established mating pattern.


Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen Jan 1964

Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen

Fisheries Research Reports

As regards both catch and value, the Shark Bay snapper fishery is the second most important scale fishery in Western Australia. Until 195%, the fishing was done solely by means of hard-lines operated from beats drifting over the snapper patches. In 1959 traps were first used with great success and in 196) this method of fishing was again the principal technique.

Prior to the 1960 season there were several suggestions that the use of traps would have a deleterious effect on the fishery. On October 19, 1959, the Western Australian League of the Professional Fishermen's Association wrote to the Fisheries …

One Shot Baiting, C D. Gooding, L. A. Harrison Jan 1964

One Shot Baiting, C D. Gooding, L. A. Harrison

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

THE Agriculture Protection Board introduced the first of its contract poisoning schemes in 1955 in the lower South-West when three units undertook the first "1080" poisoning for farmers in Western Australia.

The originators of one-shot baiting describe this new technique and explain how it should be used for best results on the farm.


Attack The Rabbit At Home : Destroy Warrens And Harbourage, J S. Crawford Jan 1964

Attack The Rabbit At Home : Destroy Warrens And Harbourage, J S. Crawford

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

Effective rabbit destruction often calls for a carefully worked out control programme consisting of poisoning, fumigating and warren and harbourage destruction.

Possibly the most effective means of not only controlling rabbits but ultimately eradicating them from holdings is the destruction of warrens and harbourage.


The Fox : Status And Control, C D. Gooding Jan 1964

The Fox : Status And Control, C D. Gooding

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

NOBODY knows for certain and it is possible that the damage done by foxes is sometimes over-rated, but the fact remains that foxes are reputed to be a real problem to some farmers at lambing time.


Dingo Control : Organised Ground Baiting Drives At Mating Time, C D. Gooding, J. J. Freeth Jan 1964

Dingo Control : Organised Ground Baiting Drives At Mating Time, C D. Gooding, J. J. Freeth

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

DINGOES in Western Australia, like all "creatures of nature", have a well defined seasonal pattern of behaviour.

This is influenced somewhat by weather variations, but even in remote areas where violent fluctuations in rainfall occur from year to year, the dingo still breeds at roughly the same time.

The numbers of pups born and the numbers which survive each year varies a lot, but life goes on at roughly the same tempo under most seasonal conditions.

An Assessment Of Cattle Husbandry Problems In Western Australia, W J O Wilkie

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

THE science of animal husbandry deals with all those things which affect the welfare and productivity of our domestic animals.

The relative emphasis placed on welfare and productivity depends on whether the animals are kept as pets or for profit.

Geographic Distribution Of Some Species Of Trichodinids (Ciliata: Peritricha) Parasitic On Fishes, Glenn L. Hoffman, Jiří Lom Jan 1964

Geographic Distribution Of Some Species Of Trichodinids (Ciliata: Peritricha) Parasitic On Fishes, Glenn L. Hoffman, Jiří Lom

United States Fish and Wildlife Service: Publications

North American Trichodina from Carassius auratus, Lepomis cyanellus, L. macrochirus, Micropterus salmoides, and Rhinichthys atratulus have been studied by the silver-impregnation method and compared with European species. T. reticulata Hirschmann and Partsch, 1955, and T. (Foliella) subtilis Lorn, 1959, originally described from European goldfish, are herein recorded from North America also. T. fultoni Davis, 1947, from Lepomis cyanellus, Micropterus salmoides, and Rhinichthys atratulus is redescribed, and T. domerguei f. magna Lorn, 1961, described from European tench and gudgeon, is considered a synonym. A Trichodina sp. from the gills of Lepomis macrochirus is described; it is almost identical with …


Annotated Checklist Of The Birds Of San Joaquin County, California, James Leroy Tate Jr. Jan 1964

Annotated Checklist Of The Birds Of San Joaquin County, California, James Leroy Tate Jr.

University of the Pacific Theses and Dissertations

Evaluation of many records is the only way valid judgments can be made on abundance and status. The necessity of obtaining exact dates, localities, numbers, and special weather conditions cannot be overemphasized. For this reason, records in supplement to this list are freely solicited.

The present checklist includes all species and subspecies for which specimens exist. In some instances sight records have been adequate reason for including a species on the list when no specimen existed. Sight records for species which are difficult to identify have been admitted upon careful editing. The author has followed the policy outlined by Griscom …


Mites On Kangaroo Rats At The Nevada Test Site, Morris A. Goates Oct 1963

Mites On Kangaroo Rats At The Nevada Test Site, Morris A. Goates

Brigham Young University Science Bulletin, Biological Series

A systematic study of parasitic mites on kangaroo rats of two species at the Nevada Test Site was conducted from August 1959 to December 1961. The intent was to determine the kinds, numbers, seasonal occurrences and ecological relationships of mites in nuclear disturbed and contiguous undisturbed areas. A total of 1,256 rats from nine plant communities was examined.

The 6,208 mites collected represented 16 species including four undescribed. Fourteen were found on both kinds of rats. Considerably more rats were infested with chiggers than with mesostigmatids. Each species of mite occurred alone on its host at least 20% of the …

Solpugida Of The Nevada Test Site, Martin Hammond Muma Aug 1963

Solpugida Of The Nevada Test Site, Martin Hammond Muma

Brigham Young University Science Bulletin, Biological Series

Study of nearly 1,000 specimens of solpugids collected in 1960, 1961, and 1962 from Mercury, Nevada, resulted in the identification and placement of 395 adults in 28 species. Eight new species are described and figured. Two new synonymies, resulting from proper association of males and females, are cited. Study of the seasonal distribution and relative abundance of the sexes of 12 common species has prompted general and specific deductions concerning the essentially unknown biology of North American solpugids. Systematic collection data furnished ecological information concerning the 12 common species.
