Overtraining In Two-Cue Discrimination Learning In Rats, Douglas Neil

University of the Pacific Theses and Dissertations

The present experiment was designed to produce additional experimental evidence on the effects of overtraining on attention in a two-cue discrimination problem. It was the contention of the present study that Sutherland and Holgate's failure to obtain equal mastery of cues was due to insufficient training. If training had been prolonged far enough equal mastery of cues should result. That is, if Ss were overtrained on a two-cue discrimination problem and tested for level of performance on each cue separately at the end of overtraining Ss would perform at near 100% on the test.

New Records Of The Pigmy Shrew Microsorex Hoyi (Baird) In Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The results of extensive trapping (ca. 7000 small mammals from the Alaskan mainland) indicate that the pigmy shrew, Microsorex hoyi (Baird), is a comparatively rare mammal in Alaska. From January, 1949, to the present, my co-workers and I have collected only seven specimens. These few animals considerably extend the known geographic range of M. hoyi in Alaska.

Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent

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

A new fossil sciurid, Citellus kimballensis, is described. This new species was found in the Kimball Formation, uppermost Ogallala (very late Pliocene) at the University of Nebraska State Museum Collecting Locality Cn-1O1, northeast of Sidney, Cheyenne County, Nebraska. Characters of the dentition and skull of C. kimballensis are compared with those of other species of the genus, and with those of Cynomys.

Trans-O-Hydroxycinnamic Acid Glucosylation In Cell-Free Extracts Of Melilotus Alba, A. Kleinhofs, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

The glucosylation of trans-o-hydroxycinnamic acid has been demonstrated in cell-free extracts of MeliIotus alba. The reaction requires UDPG, a sulfhydryl compound, and an active extract from sweet clover leaves. The product of the reaction has been tentatively identified as trans-β-D-glucosyl-o-hydroxycinnamic acid.

A Comparative Osteological Study Of Two Species Of Colubridae: (Pituophis And Thamnophis), Robert E. Bullock, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The complete skeletal anatomy of Pituophis catenifer deserticola Stejneger is described in detail. The osteology of this species is compared with that of Thamnophis radix haydeni Kennicott in the following areas: atlas, axis, first thoracic, other thoracic lumbar, anterior caudal, middle caudal, and posterior caudal vertebrae, as well as the skull and hyoid apparatus.

Many structural similarities exist in these two species of colubrids. The more important structures or aspects in which similarities were observed are: (1) the natural division of the vertebral column into regions and subregions, (2) the gross morphology of the various types of vertebrae, (3) the …

The Effect Of Neurosecretions From The Cerebral Ganglia On Blood Glucose Levels In Lumbricus Terrestris, Joan Vanderpol Craig

Masters Theses

Introduction

The presence of neurosecretory cells in the suprapharyngeal ganglia of Lumbricus terrestris has been well established (B. and E. Scharrer, 1937). Since these cells may well be the only source of hormones in this organism (B. Scharrer, 1959), the question arises as to their role in the animal's regulation of metabolism The particular aspect of this problem investigated here concerns the effect of these neurosecretory substances on the blood glucose levels in L. terrestris.

Preliminary studies by this investigator on glucose levels in earthworms revealed that blood samples of approximately 15 microliters could be obtained from each animal and …

Studies Of Cesium-137 Metabolism By Blatta Orientalis In Various Thermal Environments, Tsin Fu Chuang

Biology ETDs

The effect of temperature on cesium-137 metabolism in the oriental cockroach, Blatta orientalis, was studied. Adult and nymphal animals were fed cesium-137 to investigate the biological half-time, excretion rate, retention curve and distribution of the isotope among body tissues.

Metabolic rate studies at different temperatures showed an exponential relationship between oxygen consumption and temperature. The Q₁₀ was 2.56 for adults and 2.20 for nymphs in the 10 C – 35 C range.

Cesium-137 elimination rate increased as environmental temperature increased. The Q₁₀ for cesium-137 elimination was constant (1.2) over the 15 C – 35 C range and greatly …
