Effects Of Varying The Opportunity To Attack During A Fixed-Time Schedule, Phillip G. Muller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three White King pigeons were exposed to a fixed-time 120-second food delivery schedule and a live target pigeon. In order to evaluate whether induced aggression can take place in time periods other than immediately after food delivery, the target bird could be attacked (l) throughout the interfood interval; (2) after fixed post-food times had elapsed, or (3) after random post-food times had elapsed. When target availability was continuous or limited to random 30-second periods of the interfood interval, attacking was greatest after food delivery and decreased thereafter. Attacking did not predominate in any 15-second target access period occurring 15, 45, …

The Effects Of Artificial Destratification On Water Quality In Hyrum Reservoir, John W. Gill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hyrum Reservoir, Utah, was studied for one year during an artificial destratification project. Previously Drury et al. (1975) had studied Hyrum Reservoir for one year of stratified and one year of destratified conditions. The redistribution of dissolved oxygen to the hypolimnion significantly changed conditions for chemical and biological activities in the lower depths of the reservoir. The Aphanizomenon bloom increased with each year of destratification. The reservoir was changed by destratification so as to be suitable habitat for trout on a year round basis. Aerobic conditions prevented iron from being released from the sediment into the aqueous phase. In summary …

An Electron Microscopic Examination Of Spermiogenesis In The Recessive Sex-Linked Male-Sterile Mutant, Ms(1)10s Of Drosophila Melanogaster, Lizabeth A. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Electron microscopy of the testes of mutant ms(1)10S of Drosophila melanogaster is characterized by three major defects in the tail region of the developing spermatid. One is the apparent lack of paracrystalline body formation. The second is the loss of the primary derivative as development proceeds, and the third is the breakup and incorporation of the plasma membrane and periaxonemal sheath into membranous whorls. The mutant shows different patterns of axonemal breakup depending on the stage of differentiation in which degeneration begins. Degeneration continues until only cellular debris, scattered axonemal profiles and membranous whorls are all that are seen …

Nutrient Losses From Timber Harvesting In A Larch/Douglas-Fir Forest, United States Department Of Agriculture, Forest Service

Forestry

Nutrient levels as a result of experimental clearcutting, shelterwood cutting, and group selection cutting--each with three levels of harvesting intensity--were studied in a larch-fir forest in northwest Montana, experimentally logged with a skyline system. None of the treatments altered nutrient levels in an intermittent stream, nor were excessive amounts of nutrients lost in soil below the root zone. Under conditions on this site, skyline logging did not result in surface erosion or nutrient losses that would affect forest management.

Studies On Viruses In Water, Rex S. Spendlove, Bill B. Barnett, Dennis B. George, Dennis J. Adams, Stanley F. Hayes, Ronald B. Dean, David Ridinger, Darwin L. Sorensen

Reports

A new procedure for the detection of viral antigens in fecal material was developed. The test is performed by first diluting a fecal sample with phosphate buffered saline to give a liquid consistency. The pH is then adjusted to 8.5-9.0 and the solids are allowed to settle for five minutes. Supernatant fluid from above the fecal sediment is placed on the upper surface of a well of an inverted Immulon microtiter plate and incubated for one hour at 37 degrees C to allow virus to adsorb to the plastic. The Immulon plate is then washed three times with a Tween …

A Forest Kingdom Unlike Any Other, Kurt F. Ruppel

Undergraduate Honors Capstone Projects

Olympic National Park (ONP), a natural area 15% larger than Rhode Island, located on the Olympic Peninsula in northwestern Washington State, is a land of diverse contrasts and impressive beauty. It is also a land rich in natural resources (e.g. timber, water power, and recreational potential) that are strongly coveted by man. This dichotomy has led to a number of conflicts during the past hundred years over the policies directing the control, management, and use of this area. It is the purpose of this paper to examine the factors that have shaped that policy and to follow the changes that …

Erosion Control During Highway Construction: Volume 1, Calvin G. Clyde, C. Earl Israelsen, Paul E. Packer

Reports

Summary: Highway constuction as we know it today is a high-risk activity with respect to engendering soil erosion. In earlier days of road building, when rights-of-way were generally narrow and excavations mostly shollow, erosion was rarely a serious problem. Only occasionally was it considered necessary to design and apply specific measures for erosion control. With the advent of the superhighway involving far greater widths of right-of-way, and much deeper disturbance of the natural ground to affort the horizontal and vertical highway geometry necessary for high-speed travel, came a several fold increase in erosion potential and a direct need for specific …

Modeling The Performance Of The Intermittent Sand Filter, P. A. Cowan, E. J. Middlebrooks

Reports

Several models were developed to predict the efficiency of the intermittent sand filter (ISF) in removing algae from wastewater stabilization pond effluent; volatile suspended solids (VSS) was the analytical technique used to identify algal concentrations. The first (ISF model) and second (modified ISF model) models consisted of two distinct portions: a surface algal layer (SAL) component and a sand phase component. In the ISF model, the sand phase component was described in terms of 20 empirical sand filter efficiency terms (20 ^ coefficients); in the modified ISF model, a functional relationship between ^ and filter depth was developed. The modified …

Synchronous Flocking In Dunlins (Calidris Alpina): The Chorus Girl Hypothesis, Wayne K. Potts

Biology

The Chorus Girl Hypothesis (CGH) is presented to explain the rapid transfer of information through a flock during synchronous maneuvers. The primary feature of the hypothesis is that flock members receive information concerning the maneuver in advance of the leading edge of the maneuver wave. This advance warning allows flock members to time their own execution of the maneuver to coincide with the arrival of the maneuver wave, essentially eliminating the relatively large time lags that would be associated with a neighbor-to-neighbor transfer of information. Predictions from the CGH and the alternative Quick Reaction Hypothesis are tested. Observations suggest 11 …

Toxicity Of Carbofuran, Landrin, Croneton, And Aminocarb In Relation To Age, Sex, And Pretreatment With Piperonyl Butoxide Of Alfalfa Leafcutting Bees, Megachile Pacifica, Hani J. Al-Attar

Biology

For both sexes of leafcutter bee, the susceptibility of carbofuran, croneton and aminocarb insecticides was found to be age-dependent. The bees became more susceptible to the insecticides as the adults aged. The LD50 values for carbofuran toxicity to 1- and 4-day old male and female bees were 1.02, 0.5 (males), 1.6 and 0.78 (females) μ g/g respectively; for aminocarb 1.5, 1.3 (males) 1.9 and 1.5 (females) μ g/g; for croneton 31.02, 23.8 (males), 52.14 and 28 (females) μ g/g, and landrin to 1-day old female bees, 29.3 μ g/g. One- and four-day old males or females were susceptible to carbofuran …

The Floral Biology Of Acer Grandidentatum Nutt., Virginia L. Klomps

Biology

The floral biology of Acer grandidentatum Nutt. was studied on flowers from excised branches in the greenhouse and on trees in the field. Studies on Flowering Time Sequence both in the greenhouse and in the field showed that two types of flowers occur, male flowers with stamens only, and functionally female flowers which bear stamens that do not release pollen. Morphological development of both male and female flowers was found to follow a distinct pattern of development which is described. Results showed that A. grandidentatum is dichogamous, male and female flowers reaching and completing anthesis at different times, and that …
