Floral Vasculature As A Potential Taxonomic Character In Dalea (Leguminosae), Eugene R. Brady, Don K. Wemple, Nels R. Lersten

Proceedings of the Iowa Academy of Science

Flowers from 15 species of the genus Dalea (Leguminosae) were cleared and stained. Complete isolation of the xylem of the gynoecium, androecium and corolla from the pedicel xylem was found except in two species. The most obvious feature was the "discontinuity plate" formed by the merger of the xylem of the gynoecial traces in a characteristic mass of tracheoidal cells near the base of the flower. Variation in the floral vascular pattern appears to have taxonomic implications.

Life History Of The Northern Common Shiner, Notropis Cornutus Frontalis, In Boone County, Lowa, Everett Fee

Proceedings of the Iowa Academy of Science

The northern common shiner, Notropis cornutus frontalis, was omnivorous in its feeding, but the type of food utilized was greatly influenced by water levels. Reproduction was later in Squaw Creek than in the Des Moines River. Males had consistently higher condition factors than females. Fish grew faster in Squaw Creek than in the Des Moines River but failed to reach the length of the Des Moines River fish in their first year because of a later spawning period. Myxosporidians, nematodes, tapeworms, and copepods parasitized this species.

Spring Wood Duck Population Of Mississippi River Pool 10, Dale Hein

Proceedings of the Iowa Academy of Science

The wood duck (Aix sponsa L.) populations of Mississippi River Pool 10 were studied during the springs of 1960-1964. The major nesting areas were found along the lower 3 miles of tributary valleys and on oak-covered bluffs. Only 35% of the pairs associated with Pool 10 nested in the 50 square miles of bottomlands. Distribution of pairs among habitat types was similar for 480 pairs in 1962 as was true for 530 pairs in 1963. Morning and evening flight counts and pair counts on sample transects were used to estimate numbers. Migration, sex ratios, nesting activities, local movements and …

Some Chemical Characteristics Of Iowa Lakes And Reservoirs, Roger W. Bachmann

Proceedings of the Iowa Academy of Science

Chemical analyses were made of the surface waters of 61 Iowa lakes and reservoirs during the summer of 1964. With the exception of one bog lake, they all had typical hard waters of the bicarbonate type. Their average composition was similar to the 10-year average compositions of the Iowa and Cedar rivers. There was a tendency for the lakes lying within the Wisconsin glacial drift sheet to have higher values for all parameters measured, although the differences were not considered biologically significant.

The Effect Of Family Size, Sex Of Siblings And Ordinal Position On Personality Characteristics, Brian Kruger, W.G. Fruehling

Proceedings of the Iowa Academy of Science

This study was designed to analyze data available at Wartburg College with respect to the effects of family variables upon MMPI scores with the purpose of suggesting hypotheses which may be tested in future investigations. The subjects were Wartburg College freshmen entering in the fall of the school years 1963 and 1964. A 5% coefficient of risk was adopted. AxB factorial designs were employed in the analysis of the data. No significant results were obtained for the female subjects on any of the MMPI scales. Four hypotheses were indicated: (a) Males from large families tend to be more introverted than …

Life History And Ecology Of Western Blacknose Dace, Boone County, Iowa, 1963-1964, Richard L. Noble

Proceedings of the Iowa Academy of Science

A life history and ecology study of the western blacknose dace, Rhinichthys atratulus meleagris (Agassiz), was made on Elkhorn and Pease creeks, Boone County, Iowa. Total length equals 1.23 standard length; live length equals 1.03 preserved length; and live weight equals 0.90 preserved weight. Dace reached maturity at age II. Spawning occurred from early May through July over gravel. Number of eggs increased with length of females. Scale formation proceeded forward from the caudal peduncle at 16-20 mm standard length. Scale growth was not directly proportional to body growth. Annuli formed between March and May. Fish which lacked scales until …

An Investigation Of College Success Of Odebolt-Arthur High School Graduates, Odebolt, Iowa, Donna Yvonne Hunter

Dissertations and Theses @ UNI

Throughout the nat1on there is a rapid increase in college and university enrollments. With this ever-increasing enrollment high school students find it necessary to make earlier decisions concerning their future. Such decisions usually bring forth the question, "Will I be able to succeed in college?" Such a question places much responsibility upon the high school counselor to provide students, as well as parents, with objective information concerning this transition from high school to college. Therefore, high school counselors are in need of more valid methods of making recommendations as to possible success in colleges and universities.

Spawning Periodicity Of The River Carpsucker, Carpiodes Carpio, David J. Behmer

Proceedings of the Iowa Academy of Science

The sex ratio of river carpsuckers collected from the Des Moines River differed significantly from 1:1, females being most abundant. Spawning had already begun in early June and some fish were found ripe as late as August. No carpsuckers younger than age IV were found mature. All ripening carpsucker ovaries contained a group of eggs that seemed to be degenerating. It is not certain if carpsuckers spawn more than once in a season.

The Status Of Oak Wilt In Lowa, Harold S. Mcnabb Jr.

Proceedings of the Iowa Academy of Science

This paper is intended to review critically and briefly the research being conducted on the oak wilt disease caused by the fungus, Endoconidiophora fagacearum Bretz. Although conditions and work in Iowa will be referred to constantly throughout the course of this review, much of the material will be applicable to the other oak wilt areas of this country. Many old time woodsmen maintain the presence in oak stands at the turn of the century of what we now call oak wilt; but the first definite occurrence of this disease is indicated by photographs taken in the McGregor area in 1932 …
