Notes On The Vertebrate-Collection In The Department Of Biology, Southern Methodist University, William B. Stallcup

Journal of the Graduate Research Center

Several years ago, it became obvious that any sort of work with vertebrates undertaken at Southern Methodist University would require some sort of permanent collections serving as a basis for study. It was apparent, also, that collections of this sort would be useful in other ways to the community in general: to groups interested in nature study and conservation, to Scout groups, and to other educational organizations. The Dallas Museum of Natural History is an excellent museum from the standpoint of display of larger mammals and birds in their natural habitats, and it also houses a fine study-collection of birds …

Avoid Losses From Poison Plants, Robert Dunlop Royce

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

E VERY country in the world has its poisonous plant problems, but in Western Australia we have more than our share.

Farmers in "Poison" districts can avoid serious stock losses if they can recognise dangerous poison plants, and have a knowledge of how the concentrations of toxic substances in these plants change with the seasons.

In this article, R. D. Royce, Officer in Charge of the Botany Branch, outlines the principles involved.

Influence Of Logging On Douglas Fir Beetle Populations, R R. Lejeune, L H. Mcmullen, M D. Atkins

The Bark Beetles, Fuels, and Fire Bibliography

All species of bark beetles of economic importance prefer to attack freshly-killed host material. Logging slash, wind-throw, and fire-killed timber provide ideal breeding grounds for bark beetles. A few species, mostly in the Dendroctonus group, are able to kill living trees. When beetles in the group, raised in preferred host material, cannot find any or enough freshly-killed trees, logs, or slash to enter, they may attack living trees. In the interior of British Columbia, infestations of the Douglas fir beetle can often be traced to logging disturbance.

Bee Farming : Maintaining Productive Stock, R S. Coleman

EVERY bee hive must be a productive unit, headed by a young vigorous queen, to to make sure of the greatest possible return from capital invested in the commercial apiary.

Potassium Deficiency In Medium Rainfall Areas, William John Toms

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

IT is well known that potassic fertilisers must be used for the successful growth of subterranean clover (Trifolium subterraneum L.) on many soils in the higher rainfall districts of Western Australia.

Recent investigations have shown that some soils in medium rainfall districts are also too low in potassium to grow healthy subterranean clover pastures.

Correspondence About "Evolutionary Relationships Among The North American Mallards", Allan R. Phillips, Paul A. Johnsgard

Papers in Ornithology

The confusing leading article of the 1961 Auk calls for comment. Despite his title, "Evolutionary Relationships among the North American Mallards," the author discusses primarily geographic distributions, population sizes, egg-white proteins( !), and certain behavioral patterns. Maps are based on ". . . the literature, personal communications, and the major United States collections," " . and from additional sight and specimen records available to me"; yet only two museums other than Cornell University are mentioned in the acknowledgments. These maps show many records of platyrhynchos far to the south; sometimes (Figure 1) the reader must search hard for any hint …

Incubation, R V. Vagg

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

TH E artificial incubation of eggs is not a recent innovation. For many centuries, some species of birds—our mallee-hen being a typical example—have hatched out their eggs by the heat generated in mounds of decaying vegetation.Furthermore, they have shown considerable skill in maintaining the mounds at uniform temperatures throughout the hatching period.

A number of reptiles employ similar methods to hatch their eggs, although in these instances there does not seem to be the same need for carefully-controlled temperatures

The Social System Of The Dakota Indians, Vernon D. Malan

SDSU Extension Circulars

This study deals with the culture of the Dakota Indian as a basis for devising more effective Extension educational programs that are adapted to their values, attitudes, behavior patterns, and beliefs. Extension experience indicates a need for similar studies in other countries. The same teaching methods and motivational appeals to adapt new practices, accept new ideas and ways of living that have proven so effective in bringing about change in the dominant Anglo-Saxon rural population have been less successful among the Indian people even though significant progress is being made . This poses the question "Why?" Undoubtedly, there are many …

Broom Millet In The Market Garden, James P. Fallon

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

WHEN we think of broom millet we usually regard it as a crop for growing either under flood irrigation or in summer moist swamps for the sole purpose of producing straw for brooms.

However, the particular characteristics of the broom millet plant make it adaptable for use in the market garden as an excellent windbreak and rotation crop.

Vitamins And Their Relationship To Animal Health, J Shilkin

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

NUTRITIONAL problems are assuming more and more importance in stock as the years progress and while much stress is sometimes placed on the role of vitamins in nutrition, one should not lose sight of the fact that they are only part of a balanced ration which should include other constituents, such as proteins, carbohydrates and fats in suitable proportions.

Healthy Pastures, F E. Ryan

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

IN sweeping away forests to make room for pastures we have taken on the responsibility of maintaining these areas in a condition suitable for the growth of pasture plants.

This is done by a choice of suitable species, fertilising, cultivating, drainage, control of grazing and by weed and insect control.

Hoary Cress (Cardaria Draba (L.) Desv.), G R W Meadly

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

HOARY CRESS, known also as Hoary Pepperwort or White Weed, is a perennial plant native to t h e Mediterranean region and Western Asia.

It has spread as a weed to northern Europe including Britain, as well as to other temperate countries among which are North America, New Zealand and Australia.

Plants And Asthma, Robert Dunlop Royce

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

ASTHMA is defined in the dictionary as being a disease characterised by recurring attacks of difficulty in breathing, and the causes are stated to include the inhalation of dust, or the odour of plants, flowers or animals.

Hay fever is a similar condition and this too, is caused by plants, usually at the time of flowering, when large quantities of pollen are produced.

Strawberry Culture, K T. Whitely

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

WHETHER fresh or preserved, the strawberry finds universal favour and is regarded more or less as a luxury.

For the grower it offers the quickest cash return of all fruits, cropping in the first year. It is, therefore, very useful to a man trying to establish a fruit growing property with limited capital.

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

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

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.

Common Bean Mosaic, W P. Cass Smith

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

COMMON bean mosaic is a widespread disease which attacks both dwarf and pole bean varieties.

The disease is caused by an infective principle or virus which spreads throughout the sap of affected plants, and causes both delayed maturity and drastic reduction in yield.

Banana Cultivation At Carnarvon, J A F Lawson

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

THE banana is claimed by some authorities to be the first fruit ever used by man. Indeed, it is so widely scattered throughout the tropical countries of the world that it is very difficult to name its centre of origin.

For centuries it has been regarded as one of the most useful fruits for treating patients with digestive ailments, and over the last few decades it has been recommended by doctors, particularly for infants.

Although the protein content of bananas is low, the sugars of the ripened fruit are present in a most useful form, and the vitamin content, by …

Relationships Of Some Families Of The Suborder Passeres (Songbirds) As Indicated By Comparisons Of Tissue Proteins, William B. Stallcup

Journal of the Graduate Research Center

Ornithologists agree that any classification of birds that attempts to reflect relationship and phylogeny presents many uncertainties. This is particularly true in regard to the Order Passeriformes, which includes more living species than all other orders combined, and of which but few fossil forms are known. Within this order the greatest taxonomic problem is posed by those species assigned to the Suborder Passeres (Oscines), the true songbirds. Opinions vary widely as to the relationships of the families in this suborder and, therefore, schemes of classification. This is because these birds form a morphologically homogeneous group, and because their slight anatomical …

The Natural History Of Necturus, Iv. Reproduction, Joseph P. Harris Jr.

Journal of the Graduate Research Center

Information on the life cycle of Necturus has accumulated slowly. Naturalists long were uncertain as to whether they had adult animals, since Mitchill's (1822) mistaken idea that they get to be two feet long was widely current. Lacepede (1807) believed that mudpuppies might be larval, and their adults unknown; Say (1818) that the mud puppy was the larva of the hellbender. Barton (1807) confused the mudpuppy and the hellbender. Gray (1857) was "... inclined for the present to consider the Proteus of the Lakes as a distinct kind of Batrachian, which is arrested in its development, and never reaches the …

Pollination Studies With Native Minnesota Pyrola And Moneses Species, Lawrence C.W. Jensen

Journal of the Minnesota Academy of Science

The closely related ericaceous ericaceous genera, Pyrola L. and Monese Salisb. ex. Gray, are common throughout the world in coniferous woods of north temperate areas. Characteristically they are small herbaceous plants with basal evergreen leaves and decorative inflorescences of green, white or pink flowers appearing in the early summer. In Minnesota there are five species of Pyrola-P. asarifolia Michx., P. elliptica Nutt., P. rotundifolia L., P. secunda L., and P. virens Schweigger. There is also the one species of Moneses, M. uniffora (L.) Gray. All these occur together in abundant quantities and bloom at approximately the same time. Consequently they …
