Systematic Status Of The Mastiff Bat, Eumops Perotis Renatae Pirlot, 1965, James D. Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The mastiff bat, Eumops perotis renatae, described by Pirlot in 1966 and later elevated to specific status by the same author is herein regarded as junior synonym of Eumops perotis perotis (Schinz, 1821). Earlier reports of large Eumops from South America are reviewed in light of the present understanding of the relationship between Eumops perotis and E. trurnbulli.

Cultural Manipulation For Higher Yields, William Duncan

Department of Agronomy and Horticulture: Faculty Publications

By cultural manipulation we will mean, in a broad sense, everything a farmer might do to increase crop yields per hectare, after he decides what to plant and buys the seed. With this restriction we leave out the agricultural economist and the plant breeder. When we limit our interest to yields per hectare we introduce an element of area. This will include the crop canopy above the surface and the root system below it. Cultural manipulation also includes what the farmer might do to make best use of water, carbon dioxide, nitrogen, and essential mineral nutrients whether they occur naturally …

Development, Differentiation, And Yield, John Heslop-Harrison

Department of Agronomy and Horticulture: Faculty Publications

The task of reviewing some of the ways development and differentiation may act as determinants of economic yield would be much simpler had knowledge advanced to a point where the basic principles concerned in the control of these processes in eukaryotic organisms were clear. Unfortunately, this stage has not yet been reached. There is no shortage of schemes and hypotheses to set beside a mountain of observational and experimental data, but the unifying thread which might allow us to pick out the significant and reject the irrelevant in any particular context is still lacking. What is incontestable is that development …

Aortic Cannulation As An Experimental Tool In ¹³⁷Cs Metabolic Studies, Lyman B. Spaulding

Biology ETDs

Tissue accumulations of cesium-137 by the white laboratory rat, Rattus norvegicus, were studied by varying the length of time between isotope introduction and sacrifice, the temperature of the animal, and the route of administration of the radioisotope. Most tissues from animals in the normothermic and hypothermic condition accumulated their major ¹³⁷Cs component within the first minute of isotope introduction. The temperature of the animal (18 C) was observed to influence tissue accumulation. Hypothermia limited uptake of radiocesium by peripheral tissues but enhanced uptake by internal tissues. Route of administration (i.a. and i.p.) differences were observed for only the heart …

Enzyme Histochemistry Of The Human Carotid Body, Gerald Fine, Pablo Enriquez, Azorides R. Morales

Henry Ford Hospital Medical Journal

Histochemical enzymatic survey of 25 "normal" human carotid bodies removed at autopsy from patients three days to 83 years of age revealed a variety of oxidative and hydrolytic enzymes in the lobular and interlobular cells. The intensity of the reactions was greater in the lobular cells. Acid phosphatase was the only enzyme that was limited to the cells comprising the lobules.

Distribution Of The Porcupine, Erethizon Dorsatum, In Mexico, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The first Recent record of the porcupine, Erethizon dorsatum, from Mexico comprised fragmentary remains associated with human occupancy from a cave east of Cuatro Cienegas, Coahuila (Gilmore, 1947: 158-159). Later, Benson (1953 : 511-512) reported two specimens from western Sonora from < the lower flood plain of the Rio Sonora, close to the Gulf of California >> (one from 6 miles N Puerto Kino and the other from Rancho Santa Ana, about 45 miles W Hermosillo), and Dickerman (1962: 108) recorded the species from Hda. Las Margaritas in northern Coahuila. No additional reports of Recent porcupines from Mexico have come to our attention, and four specimens of Erethizon dorsatum couesi Mearns, 1897, in the Museum …

Tetracycline-Based Measurements Of The Bone Dynamics In The Rib Of A Girl With Hyperphosphatasia, S. Jett, H. M. Frost

Henry Ford Hospital Medical Journal

Tetracycline-based quantitative histological analysis was made of a rib biopsy taken from a girl afflicted with hyperphosphatasia. The study revealed essentially normal bone dynamics on trabeculae, but greatly increased turnover in the compacta, which was largely composed of woven bone. Since both bone resorption and lamellar bone formation could be unequivocally demonstrated on periosteal, Haversian, and cortical-endosteal surfaces, it is suggested that the direct cause of the cell behavioral abnormality responsible for this disease may arise locally within the bone, but external to the bone cells. Because of its familial nature, however, the ultimate cause probably represents an inborn intracellular …

Some Observations On Maccoa Duck Behaviour, Paul A. Johnsgard

Paul Johnsgard Collection

The recent comprehensive review of Maccoa Duck Oxyura maccoa biology by Clark (1964) has provlded the first detailed summary of the species' reproductive behaviour patterns and other aspects of breeding in this little-studied stiff-tail. It has been evident that the evolutionary relationships of the Maccoa Duck to the other southern hemisphere stiff-tails and the northern species of Oxyura are still uncertain at best, as evidenced by the varied taxonomic treatment that the Maccoa has received from Delacour and Mayr (1945), who regarded it as a race of O. australis, from Boetticher (1952), who consldered it as a race of O. …

Mourning Dove Status Report, 1967, James L. Ruos, Duncan Mcdonald

United States Fish and Wildlife Service: Publications

Nationwide dove population indexes in the 1967 Mourning Dove Status Report were obtained by essentially the same data gathering and analyzing procedures as in 1966. A refinement was made in the base year index, using the mean of the 1966 and 1967 readings as the base for all States. There was a slight adjustment in physiographic region boundaries.

An Ecotypic Differentiation Of Human And Bovine Fecal Streptococci, With Application To Human Pollution In The Yakima River, Harlen Harvey Johnson

Ecological Determination Of The Hour Of Nest Opening By An Ant, A. Dwight Smith

Loma Linda University Electronic Theses, Dissertations & Projects

The timing of daily opening of the nest entrance by the red harvester ant Popnomyrmex californicus was studied during all four seasons. Multiple regression analysis of several , environmental variables shows that the variation from day to day in mean opening time can be attributed to temperature differences, with the time that a given temperature was reached being the most important single variable for the autumn days studied. An equation incorporating this and the minimum temperature was sufficient to specify the mean opening time to within a few minutes. For the spring days, it was necessary to combine sunrise time …

Notes On Bats From The Mexican State Of Zacatecas, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Much of the Mexican state of Zacatecas lies in the area ascribed to the Mexican Plateau. Along the western border and in the southwest, however, the state encompasses a portion of the Sierra Madre Occidental, and perhaps more importantly, from a zoogeographic view, the Rio Juchipila, a major tributary of the Rio Grande de Santiago, drains the southern "panhandle." The valley of the Juchipila supports tropical vegetation as perhaps do the valleys of several other smaller tributaries of the Rio Grande that barely reach the southern part of the state. The setting of southern Zacatecas suggests, therefore, considerable faunal diversity.
