Insect Pests And Predators In Relation To Alfalfa Seed Setting In Southern Alberta And The Effects On These Insects Of Three Chlorinated Hydrocarbons, Gordon A. Hobbs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa-insect investigations, because of necessity, had been neglected in the province of Alberta during the war years. Work was resumed on this project in the spring of 1946 by the writer.

So much progress has been made in the field of insect pest control since the advent of war-born chlorinated hydrocarbons, that it was thought advisable to design an experiment which would test under Alberta conditions the results obtained in Utah where most of this type of research had been previously carried out, and would thus serve to bring investigations in this part of Canada up to date.

Aspen Defiberization And Refining Of Product, Robert Craig Jr.

Aspen Bibliography

Because of the great demand for wood fiber and because there is an abundance of aspen available¹/ for this purpose, its conversion into a usable fiberized material offers possibilities. It also affords an outlet for low-quality bolts developed in any aspen logging operation or from land of poor quality.

The Vetches And Pea Vines (Vicia And Lathyrus) Of Texas, Lloyd H. Shinners

Field and Laboratory

In technical keys, the genus Lathyrus . is characterized as having a squarely truncate stamen tube and styles hairy near the apex on the inner side only, while Vicia has an obliquely truncate stamen tube and styles hairy on the back or all around. These differences are neither well-marked nor easy to see, especially in most Texas species, which have very small flowers. For convenience the species of both genera are here treated together in a single key.

Field and Laboratory

The present Texas Academy of Science is the third of the name: (I) "Academy of Science of Texas", founded at Austin on October 27, 1880 by S. B. Buckley and Dr. F. L. Yoakum, moved to Palestine (1882), moribund for several years, and "died" about 1886, when Yoakum moved to Tyler.' (II) "Texas Academy of Science," founded at Austin on January 8, 1892, by Edgar Everhart, G. B. Halstead, A. Macfarlane, F. W. Simonds, and T. U. Taylor; published twelve volumes of transactions (1892-1912) and then sus­ pended. (Ill) "Texas Academy of Science" (the present one), was "reorganized" in 1928, …

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

The collecting of vetebrate fossils from deposits of Blancan age in Kansas, Nebraska, and Texas during the past twelve years has revealed many interesting forms. Some species have been found to have wide geographic distribution. A large sciurid related to the woodchucks has been recognized from both Kansas and Nebraska and is here described as a new genus and species.

Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent

Papers in Ornithology

An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …

A Study Of The Littoral Marine Isopod Crustacea Of The Dillon Beach Area, Robert James Menzies

University of the Pacific Theses and Dissertations

The primary purpose of this study was to provide accurate diagnoses of the littoral marine isopod crustacea in the Dillon Beach area. Such a purpose involved a much more complete study of the anatomy of the species represented in the fauna than was heretofore performed. Certain anatomical structures deemed by earlier writers as specifically diagnostic are demonstrated to be unreliable and in a great many instances other structures previously neither described or figured by American writers are considered of paramount importance in species identification. The number and magnitude of the changes proposed in this paper as illustrated in outline form …

A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley

Papers in Ornithology

The bird navigation theory as presented implies an organ or organs in the bird's physiology which are sensitive to the effect of its motion through the vertical component of the earth's magnetic field and to the effort exerted to overcome the coriolis force, due to the earth's rotation. Both these influences involve a set of lines which together form a navigational gridwork. By correlating its instantaneous land speed with the two above effects, a bird can fly to its home which is a unique point in this gridwork, or to related companion points existing in the gridwork at positions other …

The Digenetic Trematodes Of Marine Fishes Of Tortugas, Florida, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

189 species of digenetic trematodes are reported from teleost fishes of the region of Tortugas, Florida. Among these are recognized: 44 new species, 9 new genera, 44 new combinations, 14 new synonyms, and 51 new host records. Several genera and species are considered synonyms of those previously named.

Of 237 species (approximately 2,039 specimens) of teleost fishes examined, 182 species or 76.8% were parasitized by adult, digenetic trematodes. Most of the host species harbored from one to three species of trematodes; 79 (or 43.4% of the 182) had a single species of trematode. Two fishes, however, were each susceptible to …

A Study Of The Pattern Of Scale Development In Salmo Clarkii Spilurus Cope, Josephine Hawrylko

Biology ETDs

One of the phases of fish investigation is to determine the pattern of scale development is fishes. The problem deals with a study of the gross development of scales and their distribution over the body in Salmo clarkii spilurus Cope, Rio Grande Cut-throat trout. "This trout is known only from the upper Rio Grande basin and southward into the mountains of Chihuahua." The Cut-throat trout is a member of the Family Salmonidae and often goes under such common names as black spotted trout, mountain trout, New Mexico native trout, red-throat trout and various other titles.

(2) If splenectomized animals can form antibodies, and to what degree.

Effects On Different Intensities Of Utilization Upon The Underground Parts Of Short Grasses In West Central Kansas, Farrel Branson

Master's Theses or Doctor of Nursing Practice

Work on root systems of forage plants has indicated that a knowledge of root relationships is fully as important in determining the actual conditions of ranges or pastures as is knowledge of the effects of grazing upon aboveground portions of plants. This is especially true in arid or semiarid regions since plants of these areas are frequently subjected to long periods of drought, high temperatures, and high wind velocities. Some xeric plants have a thickened cuticular layer, stomates that open only at night, and other mechanisms that prevent loss of water that is absorbed by the roots. However, in plants …

A Descriptive Analysis Of The Musculature And Osseous Systems Of The Kangaroo Rat, Dipodomys Ordii, Virgil Mathis

Master's Theses or Doctor of Nursing Practice

The kangaroo rats constitute the only genus, Dipodomys, of the subfamily Heteromyinae, now extant . There is fossil evidence of two other genera which are now extinct. The kangaroo rat, Dipodomys ordii richardsoni, is one of the common rodents of western Kansas . According to Hibbard (3, p. 76), "Its range extends northeastward along the Kansas river into Riley County." These animals are easily distinguished from other rodents by their long tail, long hind legs and feet, small hands, fur lined external cheek pouches, and their saltating method of locomotion. These rodents are seldom seen by the casual observer, being …
