Habitat And Time Utilization Of A Pair Of Nesting Sharp-Shinned Hawks (Accipiter Striatus Velox) : A Telemetry Study, Joseph Belnap Platt

Theses and Dissertations

Telemetric observations were conducted on a pair of Sharp-Shinned Hawks (Accipiter striatus velox) nesting in Spanish Fork Canyon, Utah in 1972. The movements of both adults were monitored from the time their eggs hatched in late June until they left the study area in early August, fourty-two days later. A transmitter was also attached to one of the young at the time of fledging. The adult's main hunting area was a single plant community located 1600 meters from the nest. The male performed the majority of the foraging while the female spent the greatest part of her time at the …

Effects Of A Nuclear Detonation On Arthropods At The Nevada Test Site, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

Fifty-three arthropod species were studied in an area affected by an underground nuclear detonation. These were represented by 10 species of ants, 17 beetles, 5 orthopterans, 4 scorpions, 6 solpugids, and 11 spiders (Table 16). Relative populations were determined prior to the detonation and at three periods after the detonation–(1) one and two months after (August and September 1962), (2) 11 months after (June 1963), and (3) 13 months after (August 1963). One and two months after the detonation, the number of species was reduced from the expected by 48 percent, by 52 percent after 11 months, and by 66 …

An Ecological Survey Of The Algae Of Huntington Canyon, Utah, Lorin E. Squires, Samuel R. Rushforth, Carol J. Endsley

Brigham Young University Science Bulletin, Biological Series

A quantitative and ecological study of the algae of Huntington Canyon, Emery County, Utah, was conducted from March 1971 to April 1972.

Mule Deer Use Patterns As Related To Pinyon-Juniper Conversion In Utah, Ted L. Terrel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Objectives were (1) to evaluate the seasonal and daily use by mule deer (Odocoileus hemionus) of adjoining converted and natural pinyon pine-Utah juniper woodland (P-J) winter range, and (2) to determine the major factors influencing mule deer use of converted P-J range to provide criteria for deer management. The study was conducted on 3 sites in central, eastern, and southeastern Utah between 1969-72. Data for 1969-72 on physiographic, climatic, and vegetational attributes of the three Utah study areas were related to data from approximately 10,000 deer observations, 5,000 0.01-acre pellet-group count plots, feeding observations of 1,100 deer, 220 …

Vector Preference Among Varieties Of Lycopersicon Peruvianum And L. Esculentum As Related To Curly Top Virus Resistance, Stanford A. Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tests substantiating vector nonpreference as a factor in the ability of certain tomato varieties to escape curly top virus (CTV) infection were conducted and evaluated. Nonpreference is not an effective mode of resistance to CTV in tomatoes under field conditions since leafhoppers feed on and may infect plants before expressing a preference.

Preference of viruliferous leafhoppers was observed on plants of seven tomato varieties arranged both randomly and homogeneously in caged flats. Through observation of curly top symptom development, relative resistance due to vector nonpreference was calculated for each variety.

Up to 23 per cent of the fairly high resistance …

The environmental factors examined were geology, physiography, soils, climate, hydrology, and vegetation. …

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%. …

An Examination Of Legislation For The Protection Of The Wetlands Of The Atlantic And Gulf Coast States, Anthony J. Haueisen

Gulf and Caribbean Research

The most useful aquatic areas in the world are in serious danger of destruction. The estuaries, where fresh water, land and sea meet in a dynamic and highly productive zone, are today gravely threatened through unwise and unplanned excessive use of their valuable but finite capacities. Estuaries include the coastal zone which is affected by both the run-off of fresh water from the land and the salt water from the sea. This zone includes tidal rivers, marshes, bays and river mouths. The value of these estuarine regions has been well established by biologists. However, this value is fully appreciated by …

The Role Of Nematodes In A South Dakota Grassland Ecosystem, James D. Smolik

Electronic Theses and Dissertations

In an attempt to elucidate the role of nematodes in a grassland ecosystem nematode taxa, number and biomass data was gathered over a three year period at the Cottonwood International Biological Program Grassland Biome site in western South Dakota. The effects of grazing intensity, sampling date and sampling depth were studied. Nematicide treatment of range grasses in field and greenhouse studies was also used to evaluate the role of nematodes. Biomass data was used to estimate the intake of plant feeding nematodes. Results obtained demonstrate that soil inhabiting nematodes constitute a significant proportion of the consumer biomass at the Cotton[1]wood …

A Limnological Study Of Shadow Lake, A Subalpine Lake At Mount Rainer National Park, Washington, Timothy J. Hall

All Master's Theses

This paper presents a general limnological survey of a subalpine lake ecosystem. Physical, chemical and biological parameters were considered. Chemical and physical factors were dominated by the influence of snow-ice cover and high amounts of solar radiation. Abiotic factors result in a small phytoplankton standing crop and limitation of activity by photosynthetic organisms to the short summer season. Zooplankton and benthic communities are simplified in species composition and population size in response to the small primary producer population.

A Study Of The Phylogenetic Relationships Of Agropyron Scribneri, Agropyron Trachycaulum, And Sitanion Hystrix, C. Lorenzo Pope

Theses and Dissertations

Agropyron scribneri Vasey (spreading wheatgrass) is endemic to the Rocky Mountains of the Intermountain West. Each distinct population is widely separeated by valley and desert floors. It is morphologically similar to the hybrid between Agropyron trachycaulum (Link) Malte and Sitanion hystrix between Agropyron trachycaulum (Link) Malte and Sitanion hystrix (Nutt.) J. G. Smith as well as the hybrid, A. trachycaulum x A. scribneri. It appears that A. scribneri may have originated de novo from hybidization products of A. trachycaulum and S. hystrix. Agropyron scribneri appears to be morphologically similar to the population of S. hysterix with which it is associated. …

Comparative Ecological, Morphological, And Behavioral Studies Of The Southern Blacknose Dace, Rhinichthys Atratulus Obtustjs Agassiz, And The Eastern Blacknose Dace, Bhinichtbis Atbatulus Atra'fulus (Hermann), In High And Low Altitude Streams In West Virginia And Virginia, Michael L. Little

Theses, Dissertations and Capstones

Comparative ecological, aorphological, and behavioral studies of the southern blaeknose dace, Rhiniohthys atratulus obtusus Agassiz, and the eastern blaokaose dace, B.hiniohtpys atratulus atratulus (Heraann), were made in high and low altitude streaas in West Virginia and Virginia. Statistical comparisons of the morphology of a. a.atratulus and R-.a.-obtusus showed no reliable body character that differentiated the two subspecies. Statistical tests indicated an intergrading population in Gandy Creek, a tributary of the Cheat River, in West Virginia. This was further substantiated by collecting males of the atratulus phenotype along with males of the native obtusus phenotype in adjacent sections of Gandy Creek. …

Reproductive Wastage In Sheep On Clover Areas, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia's 67 per cent lambing for 1970 compares poorly with that of other Australian States, and other countries. From the 12.3 million ewes mated in this State's agricultural areas in 1970, only 8.2 million lambs were marked.

This low 77.7 per cent conception rate sparked the present series of reproductive wastage investigations by the Department's Sheep and Wool Branch.

This report describes the first year's results of the project in W.A.'s "clover disease" areas.

Bionomics Of Mallophaga Of Sharp-Tailed Grouse In South Dakota, Major L. Boddicker

Electronic Theses and Dissertations

The ecologies of chewing lice (Insecta:Mallophaga) which parasitize sharp-tailed grouse, Pedioecetes phasianellus, were studied in southwestern South Dakota from 1964 to 1967. Five hundred twenty-eight hens, cocks and chicks were collected and examined for louse damage. Louse populations were monitored each month from December, 1964, to September, 1967. Five louse species which infested grouse in the study area were Goniodes nebraskensis Carriker, Amyrsidea megalosoma Overgaard, Lagopoecus perplexus Kellogg and Chapman, Goniocotes chrysocephalus and Lipeurus maculosis Clay. Goniodes nebraskensis fed on feather parts and skin debris and was found to have seasonally fluctuating populations. Cocks carried peak populations of 250 lice/host …
