Radioisotope Feces Tagging As A Population Estimator Of Black Bear (Ursus Americanus) Density In The Great Smoky Mountains National Park, Daniel Calhoun Eagar Jun 1977

Radioisotope Feces Tagging As A Population Estimator Of Black Bear (Ursus Americanus) Density In The Great Smoky Mountains National Park, Daniel Calhoun Eagar

Masters Theses

The black bear (Ursus americanus) population in the Great Smoky Mountains National Park (GSMNP or Park) is an important renewable natural resource to the Southern Appalachian region. It is valuable as an attraction to Park visitors who annually spend millions of dollars in areas surrounding the Park; it is valuable as a yardstick against which to compare exploited bear populations in adjacent areas, and, perhaps most importantly, it is valuable as a symbol of Eastern wilderness which is being rapidly diminished by human exploitation of he environment. In order to effectively manage this resource, it is necessary to …


Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri Jan 1977

Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri

Masters Theses

Hepatozoon and microfilariae are described from the blood of fox and gray squirrels captured in Coles and Lake Counties in Illinois during 1976 and 1977. The hepatozoon species is identified as Hepatozoon griseisciuri on the basis of parasite morphology and hosts. A higher rate of infection (35.7% : 11.1%) was observed in gray squirrels than in fox squirrels and more adults were infected than juveniles. No microfilariae were found in gray squirrels but fox squirrels had a 57.1% infection rate with no difference based on age. The observed microfilariae are similar to that described by Davidson from Maryland gray squirrels …


The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace Jan 1977

The Effects Of Superovulation On The Reproductive Cycle Of Mature Female Mus Musculus, David F. Grace

Masters Theses

A total of 38 Mus musculus were used to compare superovulation to normal ovulation in three different areas of the reproductive cycle. The areas studied include the fertilization and abortion rates, alternation of ovarian function, and normalization of estrus cycling. No statistically significant differences were noted between the two groups in either fertility rates or abortion rates. A distinct difference was noted in alternation of ovarian function. Normally ovulating mice showed a distinct right or left preference in the number of ova ovulated from each ovary. Animals showing a left preference exhibited approximately a 2:1 ratio and animals with a …

A Cytogenetic Study Of Xx/Xy Chimerism And Other Anomalies Of Bos Taurus In A Sampled Dairy Herd, Ferne M. Rogers Jan 1977

A Cytogenetic Study Of Xx/Xy Chimerism And Other Anomalies Of Bos Taurus In A Sampled Dairy Herd, Ferne M. Rogers

Masters Theses

The establishment of normal chromosomal patterns for a wide range of plants and animals has led to the recognition of abnormalities as well as their relationship to phenotypic irregularities. Research dealing with the expression of human karyotype is of prime interest; but, closely rivaling that is the genetic study of domestic animals which are of economic importance to man.

One observed anomaly which has come under scrutiny by cytogeneticists is that of the female member of a heterogeneous bovine twin pair, the freemartin. This is a sterile animal with internal morphology showing varying degrees of intersex. Cytogenetic studies reveal XX/XY …

Production And Utilization Of Sunflower Food Plots At Shelbyville Wildlife Management Area, Illinois, Duane T. Dust Jan 1977

Production And Utilization Of Sunflower Food Plots At Shelbyville Wildlife Management Area, Illinois, Duane T. Dust

Masters Theses

Three sunflower (Helianthus annuus) fields from 3.2 ha to 1.0 ha in size, planted on the Shelbyville Wildlife Management Area, Illinois were analyzed for seed production and utilization by birds. Seed in heads and on the ground were sampled and species and numbers of birds in the fields were censused at two week intervals from September, 1976 to February, 1977. Decline in seed availability was most rapid in the smallest field and least rapid in the largest field. Fields and portions of fields adjacent to wooded cover were also utilized more rapidly. American goldfinch (Spinus tristis) …
