Lesioning Of The Nucleus Of The Hippocampal Commissure Followed By Food Deprivation Stress In Birds Demonstrates Simultaneous Involvement In Both The Hypothalamo-Pituitary-Adrenal Axis And The Hypothalamo-Pituitary-Thyroid Axis, Michael Thomas Kidd Jr.

Graduate Theses and Dissertations

The hypothalamo-pituitary-adrenal (HPA) axis is the regulatory system for the neuroendocrine stress response within vertebrates. Within the HPA axis corticotropin releasing hormone (CRH) is a major regulator and driving hormone. A structure named the nucleus of the hippocampal commissure (NHpC) has been found to contain CRH neurons and also these neurons respond to early food deprivation stress significantly prior to the paraventricular nucleus (PVN), the major driving nucleus of the classic neuroendocrine HPA axis. The objective of this study was to perform a knock down of the NHpC via electrolytic lesioning, thus eliminating a significant portion of its population of …

The Rise And Fall Of Kin Structure In The Neotropical, Family-Living Buff-Breasted Wren (Cantorchilus Leucotis) In Gamboa, Panama, Sarah C. Alessi

Masters Theses

Family-living species provide an exciting model to examine how natal dispersal and kin structure influence genetic structuring within local populations. Juvenile buff-breasted wrens (Cantorchilus leucotis) of both sexes delay dispersal and exhibit short-distance natal dispersal, which should lead to kin-structured populations in which relatives of both sexes occupy neighboring territories. Blood samples collected from juvenile and adult wrens in Gamboa, Panama were analyzed using microsatellite markers to determine whether related individuals are spatially clustered on neighboring territories, spatial clusters of relatives change over time, and if kin structure is sex-specific. Global and local spatial autocorrelation analyses detected genetic …

The Feasibility Of Avian Karyotypes In Taxonomy, Gerald Francis Shields

All Master's Theses

The purpose of this paper is twofold: first, to evaluate the usefulness of various karyotypic procedures using domesticated and passerine birds and second, to comment on the validity of the application of karyotypic data to taxonomy.

Annotated Checklist Of The Birds Of San Joaquin County, California, James Leroy Tate Jr.

University of the Pacific Theses and Dissertations

Evaluation of many records is the only way valid judgments can be made on abundance and status. The necessity of obtaining exact dates, localities, numbers, and special weather conditions cannot be overemphasized. For this reason, records in supplement to this list are freely solicited.

The present checklist includes all species and subspecies for which specimens exist. In some instances sight records have been adequate reason for including a species on the list when no specimen existed. Sight records for species which are difficult to identify have been admitted upon careful editing. The author has followed the policy outlined by Griscom …
