Assessment Of Fawn Breeding In A South Carolina Deer Herd, Olin E. Rhodes Jr., James M. Novak, Michael H. Smith, Paul E. Johns

Faculty Research & Creative Activity

Annual variation in breeding success among female white-tailed deer (Odocoileus virginianus) fawns on the Savannah River Plant (1967 to 1985) was determined from direct counts of pregnancy in spring-collected fawn females and evidence of lactation and measurements of udder thickness in fall-harvested 1. 5-yearolds. Percent lactation in 1.5-year-old females collected during September and October gave the best estimate of fawn breeding in the previous year. The overall mean fawn breeding estimate from September and October was 41 % , and the yearly variation in fawn breeding was significant. An estimate of the average yearly contribution to recruitment was 43 fetuses …

Differentiation Of Murine Erythroleukemic Cells During Exposure To Microwave Radiation, Roger F. Brown, S. V. Marshall

Biological Sciences Faculty Research & Creative Works

Cultures of murine erythroleukemic cells undergoing erythroid differentiation in response to induction by hexamethylene bisacetamide (HMBA) were exposed to 1180-MHz microwave (MW) radiation for 48 h while maintained at 37.4°C by variable-temperature air flow. Exposures at 1180 MHz were at 5.5, 11, and 22 mW/cm2 with a normalized specific absorption rate of 3.32 W/kg per mW/cm2. HMBA-induced control cells were incubated in a 37.4°C water bath. Mean cell doubling time was 16.5 h in both the irradiated cultures and the control cultures. About 65% of the cells of irradiated cultures and control cultures were benzidine-positive differentiated cells. Both the irradiated …

An Annotated List Of The Butterflies Of Kansas, Charles A. Ely, Marvin D. Schwilling, Marvin E. Rolfs

Fort Hays Studies Series

This provisional list summarizes the information currently available on the distribution of the butterflies of Kansas. Presently, this information is widely scattered in the literature and numerous collections and is not readily available to many interested parties. The accompanying maps also demonstrate the many gaps in our present information and will hopefully stimulate further collecting and the production of a more complete list in the near future. This paper is based primarily on collections made by the authors during an intensive statewide survey begun in 1979. It is organized around the "county record," usually a voucher specimen housed at Fort …

Repair-Deficient Xeroderma Pigmentosum Cells Made Uv Light Resistant By Fusion With X-Ray-Inactivated Chinese Hamster Cells, Deneb Karentz, James E. Cleaver

Biology Faculty Publications

Xeroderma pigmentosum (XP) is an autosomal recessive human disease, characterized by an extreme sensitivity to sunlight, caused by the inability of cells to repair UV light-induced damage to DNA. Cell fusion was used to transfer fragments of Chinese hamster ovary (CHO) chromosomes into XP cells. The hybrid cells exhibited UV resistance and DNA repair characteristics comparable to those expressed by CHO cells, and their DNA had greater homology with CHO DNA than did the DNA from XP cells. Control experiments consisted of fusion of irradiated and unirradiated XP cells and repeated exposure of unfused XP cells to UV doses used …

Evolution Of Feeding And Case-Making Behavior In Trichoptera, John S. Weaver Iii, John C. Morse

Publications

A phylogeny of the families of Trichoptera is reviewed to provide a basis for understanding the probable evolution of feeding tactics and case or retreat constructions by larvae. At lease 48 hierarchically inclusive homologues are known, mostly from larval, pupal, and adult morphology. Their resulting phylogeny indicates that Rhyacophilidae, Hydrobiosidae, Glossosomatidae, and Hydroptilidae are more closely related to Philopotamidae, Hydropsychidae, and their allies than to Limnephilidae, Leptoceridae, and their allies. This phylogeny implies that the ancestral caddisfly larva was probably a tube-dwelling detritivore, inhabiting humus and detrial mats near the shores of lentic or lotic-depositional habitats. This ancestor evolved into …

A New Braconid Genus (Hymenoptera) Parasitizing Webspinners (Embiidina) In Trinidad, Scott Shaw, Janice Edgerly-Rooks

Biology

Early in 1984, while conducting field studies on embiid behavior in the Arima valley of northern Trinidad, the junior author ob- served a braconid wasp ovipositing into the silk webs of an embiid, Clothoda urichi (Saussure) [Clothodidae]. The wasp and a paralyzed embiid were collected, and another wasp was successfully reared from that host. Specimens were sent to the senior author, then stationed at the National Museum of Natural History (USNM), who determined it to be a new braconid genus. A search of the USNM collection yielded no comparable specimens; however, during a subsequent search of the Museum of Comparative …

Schistosomiasis A Public Health Concern, Greg Maciel

Whittier Scholars Program

This project is a research paper on the parasitic disease, schistosomiasis. Schistosomiasis can cause illness, disability, and in some cases, death. Schistosomiasis survives in climates that range from tropical to temperate. The disease is most prevalent in underdeveloped areas where sanitation is poor. These underdeveloped areas have little money for treatment and controls. And because the disease prevents people from working, the economy of these infected areas can suffer. Without eradication efforts, schistosomiasis can be spread to the whole population. In trying to control schistosomiasis people are looking for the most thorough and least expensive methods. This paper will be …

Diphtheria, Pertussis, Tetanus Vaccine: Mandatory Child Immunization And Public Policy, Lynette Dockstader-Smiley

Whittier Scholars Program

Through the use of public policy analysis, this project examines mandatory vaccination policy in the United States, and particularly in California. The project also addresses social issues surrounding the vaccine for Diphtheria, Pertussis, and Tetanus (DPT), with an emphasis on the responsibilities of physicians and patients. The roles of policy makers and organizations are examined, as well as the issues that arise when too much control of public health is given to one group. The project concludes with an analysis of what the public does to encourage changes in public health policy.

Human And Natural Causes Of Marine Turtle Clutch And Hatchling Mortality And Their Relationship To Hatchling Production On An Important Florida Nesting Beach, Blair E. Witherington

Retrospective Theses and Dissertations

Populations of Western Atlantic loggerheads (Caretta caretta) and Florida green turtles (Chelonia mydas) have been in historical decline. The identification and protection of beaches that are major producers of loggerhead and green turtle hatchlings are vital to the preservation of these species.

A study assessing loggerhead and green turtle hatchling production was initiated at a 21 km stretch of beach in south Brevard County, Florida (Melbourne Beach) during the 1985 nesting season. Nesting densities were assessed from a season-long (10 May – 12 September) census in which every nest was counted and identified to species. An analysis of average reproductive …

Comparative Reproductive Success Of Yellow-Shafted, Red-Shafted, And Hybrid Flickers Across A Hybrid Zone, William S. Moore, Walter D. Koenig

Biological Sciences Faculty Research Publications

Alternative hypotheses of hybrid zones make specific predictions about reproductive components of fitness in the hybrids. The dynamic-equilibrium and reinforcement hypotheses are premised on reduced hybrid fitness, which should be apparent as reduced clutch or brood size or as increased embryonic mortality. The hybrid-superiority and introgression hypotheses predict normal clutch and brood size and embryonic mortality.

Reproductive success was measured at four study sites on a transect across the hybrid zone between the Yellow- (Colaptes auratus auratus) and Red-shafted (C. a. cafer) subspecies of the Northern Flicker. Two additional clutch size samples representing pure Yellow- and …

Florida Macrolichens As Potential Bioindicators Of Environmental Quality: A Baseline Study, Harry V. Neal

Retrospective Theses and Dissertations

Lichens have been used extensively and with considerable success as bioindicators of atmospheric pollution in North America and Europe for more than thirty years. Little research has followed in tropical and subtropical regions where population growth is rapid and environmental pressures unprecedented. However, taxa used as bioindicators in other studies and/or taxa having this potential, occur naturally in Central Florida. A new potential major source of pollution, the coal-fired Curtis H. Stanton Energy Center, is about to begin operation providing the opportunity to determine the extent of impact. Therefore, lichen monitoring sites have been established and the collection of baseline …
