Further Studies In The Ecotone Between Prairie And Woodland, R. J. Pool, J. E. Weaver, F. C. Jean
Further Studies In The Ecotone Between Prairie And Woodland, R. J. Pool, J. E. Weaver, F. C. Jean
University Studies (University of Nebraska) (1888–1984)
A series of intensive investigations of the ecological features of the tension zone between prairie and woodland in the Mississippi valley was begun by Weaver and Thiel in 1915. These studies were continued for two seasons in Minnesota and were also extended to the prairies of eastern Nebraska in 1916. These investigations represent the first attempt to attack the prairie-forest problem on a comprehensive scale by means of the quantitative methods of modern ecology. Some of the results secured from these studies have been published as the first paper of a series planned to deal with critical investigations in the …

Upon the completion of a series of investigations in southeastern Washington and adjacent Idaho, in which there was found to be a direct relation between the available water content of the soil and the evaporating power of the air as succession progressed from grassland through scrub to forest, the senior writer moved to Minneapolis, Minnesota. Here such excellent conditions of prairie invaded by scrub and followed by forest offered themselves for study that the services of the junior author were enlisted and an analysis of the situation attempted. Later this study was supplemented by similar work carried on at Lincoln, …

Plant Studies In Lyon County, Iowa, D. H. Boot
Proceedings of the Iowa Academy of Science
The subject of this paper is one of a series of ecological studies carried on by the author during the last few years, and is a study of a part of the region, consisting chiefly of high prairie, in the northwestern part of the state, the tract considered covering a part of the southwest corner of Lyon County, which is the northwesternmost county in Iowa.

Weed Survey Of Story County, Iowa, L. H. Pammel, Charlotte M. King
Weed Survey Of Story County, Iowa, L. H. Pammel, Charlotte M. King
Proceedings of the Iowa Academy of Science
The matter of the distribution of weeds is one of interest, not only to the phytogeographer, but to the farmer and horticulturist as well. Our alien flora, though Iowa is not an old state, is a large one. In 1879 Dr. Gray prepared a list of the predominant weeds of Eastern North America. In a discussion of weed migration in The Weed Flora of Iowa, I made a comparison of weeds and alien plants in Iowa. In counting the weeds of Iowa I find that 172 of that list occur in Iowa. This list can be augmented by the addition …

Twenty-Five Years Of Botany In Iowa, Thomas H. Macbride
Twenty-Five Years Of Botany In Iowa, Thomas H. Macbride
Proceedings of the Iowa Academy of Science
To tell of Botany in Iowa for twenty-five years, even as presented in the work of members of this Academy, is a task far more difficult than would at first appear. Shall I present a list of all Iowa botany papers for a quarter of a century; such list would mean much indeed, and such list so far as attainable may be found as an appendix to the present paper. But the slightest reflection suggests that such list, long or short, is, as a matter of fact, no measure whatever of either the industry or the achievements of those who …

An Ecological Study Of A Prairie Province In Central Iowa, Ada Hayden
Proceedings of the Iowa Academy of Science
This virgin prairie area is mostly of the kame hill, saucer type. One portion of the territory is probably the pre-Wisconsin bed of the Des Moines River whose course was changed by the ice sheet. The region examined in detail is one mile in radius and bordered by a woodland adjacent to Skunk River.

Floristic Notes From An Illinois Esker, Bruce Fink
Floristic Notes From An Illinois Esker, Bruce Fink
Proceedings of the Iowa Academy of Science
Kaneville is a village in Kane County, Illinois, and is situated about fourteen miles from Aurora, Illinois, west by a few degrees north. At Kaneville, the present writer passed several years of his boyhood and early youth, and here it was that he took his first lessons in natural science, learning the names and habits of a considerable number of birds and plants and gaining some inklings of the interesting mysteries of geological science.
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 …
