Beitrag Zur Kenntnis Der Mit Tetralonia Verwandten Bienen Aus Sudamerika., A. W. Bertoni, C. Schrottky

Ba

Unter dem Sammelnamen TetraZonia sind in den letzten Jahren eine Menge neuer Arten aus Südamerika beschrieben worden, ohne daß deren Verwandtschaft angegeben wäre, oder aber, wo die neuen Arten auf verschiedene Gattungen verteilt wurden, ist dies einzig auf die Zahl der Palpenglieder hin erfolgt, ein Verfahren, das niemals gebilligt werden kann, weil eine auf nur ein Organ begründete Einteilung notwendigerweise mangelhaft sein muß. Es ist daher wohl zu entschuldigen , wenn mehrere Bearbeiter den in dieser Gruppe aufgestellten neuen Gattungen überhaupt keine Beachtung schenkten. Indessen sind die Schwierigkeiten, sich in der wachsenden Zahl der „Tetralonia"-Arten zurechtzufinden, immer größer geworden, so …

Fearsome Creatures Of The Lumberwoods: With A Few Desert And Mountain Beasts, William T. Cox, Coert Du Bois

Nebraskiana Publications: Resources and Materials on the 37th State

Every lumber region has its lore. Thrilling tales of adventure are told in camp wherever the logger has entered the wilderness. The lumber jack is an imaginative being, and a story loses none of its interest as it is carried and repeated from one camp to another. Stories which I know to have originated on the Penobscot and the Kennebec are told, somewhat strengthened and improved, in the redwood camps of Humboldt Bay. Yarns originating among the river drivers of the Ottawa, the St. Croix, and the upper Mississippi are respun to groups of listening loggers on Vancouver Island. But …

Organization And Polarity Of Protoplasm, John P. Munson

All Faculty Scholarship for the College of the Sciences

In higher forms of life, we usually concede the presence of an organ specialized for the performance of a function. In these higher forms coordination of organs, which entails a regular sequence in their functions, is readily made out; and it seems a mere platitude to say, of these, that organization determines the functions of the organism. To what extent can functions exist in the absence of organization; does the one precede the other; or have function and organization developed simultaneously, out of matter devoid of both structure and function? In my studies on the cell, I have kept these …

The Inheritance Of Sizes And Shapes In Plants, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Some years ago Lock reported a cross of a tall race of maize with a shorter race which produced an intermediate height in F₁ and exhibited no segregation in F₂ when crossed back with one of the parents. Castle's results with rabbits are very similar to those of Lock with maize. Castle summarizes his results in part as follows:

A cross between rabbits differing in ear-length produces offspring with ears of intermediate length, varying about the mean of the parental ear-lengths. . . . A study of the offspring of the primary cross-breds shows the blend of the …

Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia

Bulletins 1 - 2999

Many settlers, new to this State, find some difficulty in distinguishing those vegetable pests which are classed as noxious weeds, the eradication of which is made compulsory under the Noxious Weeds Act of 1904.

In order to facilitate the ready recognition of the plants which are the least familiar, the Department of Agriculture has prepared this Bulletin, giving illustrations of the several varieties which have been gazetted as noxious. these are: - Stinkwort, Bathurst Burr, Noogoorn Burr, Nut Bramble, Spanish Radish, Prickly Pear, Apple of Sodom, sweet Briar, Wild Bramble, Star Thistle (purple), Double Gee and Water hyacinth.

Bulletin No. 106 - A Study Of The Production And Movement Of Nitric Nitrogen In An Irrigated Soil, Robert Stewart, J. E. Greaves

UAES Bulletins

The problem of maintaining the nitrogen content in our agricultural soils is one of vital importance to the development of a permanent system of agriculture. Any investigation, therefore, which tends to throw any light on the conditions which are necessary for maintaining the maximum supply of nitrogen in our soils needs no apology for its institution.

Bulletin No. 107 - Improvement Of Utah Horses, John T. Caine Iii, H. J. Frederick

UAES Bulletins

Horse breeding in Utah, with some exceptions, has been carried on in a hap-hazard manner, and unsound horses of doubtful breeding have been purchased at high prices and have proven of little value. Where good blood has been introduced the temporary improvement has been marked, but as this work has not been followed up with care, results have not been lasting.

In spite of bad breeding, however, the standard of Utah horses has been advancing so that in western markets they command high pries. The climate, soil, feed and general conditions throughout the state make it an ideal place for …

Bouwstoffen Voor De Hymenopteren-Fauna Van Belgie, Joseph Bequaert

Ba

In mijne beide vorige mededeelingen over de belgische Hymenoptera, gaf ik een zeer beknopt overzicht der genera van de meeste onzer inheemsche Aculeata en drukte tevens de hoop uit later een volledig overzicht der Belgische soorten uit deze groep in het licht te geven. Op een volledige naamlijst onzer vliesvleugelige insecten zal men ongetwijfeld nog lange jaren wachten, te meer daar zulk werk niet door een enkel onderzoeker kan opgemaakt worden, maar de vereenigde krachten van velen zal vereischen.

Bulletin No. 105 - Factors Influencing Evaporation And Transpiration, John A. Widtsoe

UAES Bulletins

The irrigation investigations conducted by the Utah Experiment Station, some of the results of which form this *report, were undertaken for the purpose of adding to our knowledge of the natural laws upon which the art of irrigation may be safely built. The work has had for its dirrect object the study of the mutual relations of plants, soils and water, as these relations may indicate the most economic use of water for plant production. In pursuit of the investigations it became necessary not only to follow the movement of water in soils under irrigation conditions, but to determine also …
