Speciation In The Genus Sceloporus Sceloporus (Sauria, Iguanidae) As Determined By Cranial Osteology And Other Characters, Kenneth Rex Larsen May 1973

Speciation In The Genus Sceloporus Sceloporus (Sauria, Iguanidae) As Determined By Cranial Osteology And Other Characters, Kenneth Rex Larsen

Theses and Dissertations

Numerical statistical methods were used to analyse the species in the genus Sceloporus using cranial osteology, external meristic and numeric characters, karyology, display behavior and geographic distribution. A new phylogeny for the genus is proposed with three main branches or Groups: Group I, a primitive group, evolved from Uta, Urosaurus and Sator in Miocene times. This Group speciated from gadoviae in the south to merriami in the north and contains 7 species in 3 species groups. Group II arose from Group I and evolved from centrally located pictus in all directions throughout Mexico. It contains approximately 19 species in 5 …

Introductory Remarks, Leo Schelbert

Swiss American Historical Society Newsletter

It is a great pleasure to present in this newsletter Part Two of Professor Heinz K. Meier's absorbing sketch of the history of the Swiss American Historical Society. He shows ppw many minds tried their best in making the organization relevant, and their efforts remain an inspiration to those engaged in carrying on what they had so enthusiastically begun. Success based on competence and unity of purpose does not come easily as Professor Meier's story clearly shows, but the perspective of time reveals past crises as seemingly unavoidable growth pains and selfless respect for the work of others as perhaps …

Short Reviews And Notices, Leo Schelbert

Swiss American Historical Society Newsletter

The family of Hans Ulrich Baggens toss of Rafz, Switzerland, arrived in Pennsylvania in 1743. Two m9re immigrations of Baggenstoss families from Rafz followed - one settled in Minnesota (1879); the other in Tennessee (1895). All appear related to the same Swiss ancestry. The earliest record of the name is found in 1401.

History Of The Swiss American Historical Society, Heinz K. Meier May 1973

History Of The Swiss American Historical Society, Heinz K. Meier

Swiss American Historical Society Newsletter

The decade of the 1930's was a difficult time for most Americans with the depression blighting untold families and individuals. The Swiss Americans, like other ethnic groups, had an additional cause for concern inasmuch as the decade was characterized by isolationism in foreign relations and a wave of nativism at home. The introduction of immigration quotas in the 1920's indicated that the United States prepared itself to put obstacles in the way of free access to the country. Due to the depression the quotas were not even used up by most European countries. The "distant magnet" had lost much of …

Growth And Development Of The Western Harvest Mouse, Reithrodontomys Megalotis Megalotis, Gary H. Richins Apr 1973

Growth And Development Of The Western Harvest Mouse, Reithrodontomys Megalotis Megalotis, Gary H. Richins

Theses and Dissertations

Growth rates, gestation period, litter size, reproductive age, sex ratios, and development were studied on 198 litters of Reithrodontomys megalotis megalotis. Growth was characterized by several standard skull and body measurements, and was partitioned into four phases of 1-3, 4-12, 13-22, and 23-70 days. Growth was best described by measurements of tail length, ear length, and dried eye lens weight. Reproductive activity began as early as 38 days for females and 59 days for males. Gestation period was 22 days and mean litter size was 3.83 (range 1-7). Sex ratio was 53.49% males to 46.51% females. Reproductive efficiency was 53.53%. …

The Effects Of Penicillin Upon The Fission Rate Of Dugesia Dorotocephala., John J. Fahsbender Apr 1973

The Effects Of Penicillin Upon The Fission Rate Of Dugesia Dorotocephala., John J. Fahsbender

Theses and Dissertations

Planaria (class Turbellaria) are the highest life forms which exhibit fission (Hyman, 1951). The laboratory planarian, Dugesia, lives in lakes, ponds, streams and springs, where it occupies bottom habitats. Fissioning is an asexual mode of reproduction. The fission plane is usually transverse, forming behind the pharynx, and separation appears to be dependent upon locomotion (Curtis, 1902). The posterior half of the worm adheres to the substratum while the anterior half continues to move forward until the worm snaps in two. Each half then regenerates the missing parts, forming two new smaller worms.

Development Of Standard Procedures For Determination Of [Delta]G° (K), [Delta]H° And [Delta]S° Values Via Potentiometric And Calorimetric Titration Techniques, Jack Hugh Ruckman Apr 1973

Development Of Standard Procedures For Determination Of [Delta]G° (K), [Delta]H° And [Delta]S° Values Via Potentiometric And Calorimetric Titration Techniques, Jack Hugh Ruckman

Theses and Dissertations

Standard computer techniques were developed for computation of ΔG° values from potentiometric titration data and ΔH° values from calorimetric titration data. The procedures developed can be used for any systems having the general equations HA = W^+ + A^- ; H_2A = 2H^+ + A^2- ; and H_3A = 3H^+ + A^3-, where the proton ionizations may be consecutive or simultaneous. The thermodynamic values ΔG°(K), ΔH° and ΔS° were determined for the ionization of protons from the protonated compounds methionine (-NH_3^+ group only), phosphoethanalomine and phosphoserine. The compounds studied were selected because they contain one, two and three ionizable protons …

The Effects Of Thiamin Deficiency And Thiamin Antagonists On Cardiac Function In The Rat, D. James B. Sutherland Apr 1973

The Effects Of Thiamin Deficiency And Thiamin Antagonists On Cardiac Function In The Rat, D. James B. Sutherland

Theses and Dissertations

A study was made to determine what biochemical changes were involved in the slowing of the rat heart rate during thiamin deprivation, pyrithiamin or oxythiamin treatment. The appearance of bradycardia during progressive thiamin deficiency was shown to be related to the reduction in myocardial enzymatic activity of pyruvate (PDH) and 2-ketoglutarate (2-KGDH) dehydrogenase, and not due to inanition alone since pair-fed control rats did not show bradycardia until the agonal stage. Bradycardia was not the result of reduced energy since CP, ATP, ADP, and AMP levels remained normal even though PDH and 2-KGDH activity dropped to 20% of normal by …

Little Drum Mountains, An Early Tertiary Shoshonitic Volcanic Center In Millard County, Utah, Stephen H. Leedom Apr 1973

Little Drum Mountains, An Early Tertiary Shoshonitic Volcanic Center In Millard County, Utah, Stephen H. Leedom

Theses and Dissertations

The Little Drum Mountains represent a deeply eroded Eocene-Oligocene volcano, consisting of a vent complex which erupted mafic flows and flow breccias, accompanied by lahars. Flows are dominated by members of the shoshonite suite and contain up to 3.95 percent K2O, mainly occult in K-rich glass, with K2O/Na2O ratios greater than 1.0. In a few interbedded flows, apparently of the calc-alkaline series, pyroxene with varying amounts of plagioclase in a fine-grained groundmass of plagioclase, mafic minerals, and interstitial glass. An ash-flow tuff of the Oligocene Needles Range Formation unconformably overlies the volcanic sequence. Contemporaneous …
