On The Movements Of Petals, Esther Pearl Hensel
On The Movements Of Petals, Esther Pearl Hensel
University Studies (University of Nebraska) (1888–1984)
The following paper has to do with an investigation of the physical causes· which bring about opening and closing movements, periodic or otherwise, of certain flowers. With that end in view, seven different species of flowering plants have been experimented upon directly, a much larger number being simply observed with respect to the nature, time, etc., of their anthotropic movements. Movement consists in the corolla taking upon itself either the open or closed position for certain periods of the day or night; for example, the morning glory (Ipomoea purpurea) opens early in the morning (from 4:00 to 5 …

Plant Migration Studies, Charles E. Bessey
University Studies (University of Nebraska) (1888–1984)
It is a familiar fact that new species appear from time to time among the native plants of a region. Such newcomers turn out on examination to be new only in the sense that they have not previously lived in the region, and in every instance these new plants are found to have come from other regions where they had existed for a longer or shorter period of time. In some cases the new species remain for a time and then disappear, or at least become inconspicuous, but more commonly they crowd in among the former plants and become permanent …

The Relation Of Leaf Structure To Physical Factors, Edith Schwartz Clements
The Relation Of Leaf Structure To Physical Factors, Edith Schwartz Clements
School of Biological Sciences: Faculty Publications
The leaf, as the seat of important physiological functions of the plant, and because of its modification by external factors, has long been a fruitful subject for investigation. As a rule, however, investigators have confined themselves solely to the histology and morphology of the leaf, independent of its relations to physical factors. Where the latter have been considered at all, it has been in a more or less general way, or undue importance has been assigned to one or another of the physical factors, and others have been ignored entirely. In no case have they been carefully measured. The aim …

Les Hymenopteres don’t il est question dans cette etude appartiennent au genre Vespa, lequel fait partie de la famille des Vespides. Ceux-ci terminent un des rameaux de l’arbre philogenetique des Hymenopteres, don’t le tronc est forme par ces insectes don’t les larves purvoient ells-memes a leur nourriture et vivent de matieres vegetales. Au fur et a mesure que l’on s’eleve de la souche aux rameaux, on reconnait que l’instinct s’est modifie avec la maniere de vivre.

A Preliminary Review Of The Birds Of Nebraska With Synopses, Lawrence Bruner, Robert H. Wolcott, Myron H. Swenk
Papers in Ornithology
In 1896, Prof. Bruner published his list entitled "Some Notes on Nebraska Birds." As a working basis for the study of the ornithology of the state it has proven invaluable and it has also been greatly in demand by people not ornithologists, who desired to "know something about our birds." That edition was exhausted some time ago and its author has been frequently urged to publish another. However, the organization of the Nebraska Ornithologists' Union and the development of ornithology in the University has led to such a rapid increase in our knowledge in the past five years that it …

Die Kirby'sche Art ist von den Autoren, Smith folgend, stets fur O. fulviventris Panz. gehalten worden. Diese Art wurde aber in England nie gefangen, kann also den englischen Forschern nicht vorgelegen haben. Kirby, dem die Beschreibung Panzer's sicher bekannt gewesen ist - er fuhrt seinen Namen oft an -, vergleicht seine O. leaiana nicht einmal mit O. fulviventris Pz., was er sicher gethan hatte, wenn ihm beide identisch erschienen waren. Durch die Freundlichkeit Mr. Morice erhielt ich von der Osmia fulviventris K., Sm., Saund. (nec Panz.) ein Parchen, welches ganz mit O. solskyi Mor. ubereinstimmt. -Dieser Name ist also zu …
