The Ecology Of Translocated Greater Sage-Grouse In Strawberry Valley, Utah, Rick Joseph Baxter

Theses and Dissertations

Manuscript No. 1 Translocations of greater sage-grouse (Centrocercus urophasianus) have been attempted in 7 states and one Canadian province with very little success. To recover a small remnant population and test the efficacy of sage-grouse translocations, we captured and transported 137 adult female sage-grouse from 2 source populations to a release site in Strawberry Valley, Utah during March-April 2003-2005. The resident population of sage-grouse in Strawberry Valley was approximately 150 breeding birds prior to the release. We radiomarked each female and documented survival, movements, reproductive effort, flocking with resident grouse, and lek attendance. We used Program MARK to calculate annual …

Adaptation To Deep-Sea Hydrothermal Vents: Some Molecular And Developmental Aspects, Florence Pradillon, Françoise Gaill

Journal of Marine Science and Technology

Alvinella pompejana is a polychaetous annelid inhabiting the surface of deep sea hydrothermal chimneys along the ridge of the east part of the Pacific ocean. The main characteristic of this emblematic species is its habitat, which is very aggressive considering its temperature. The exceptional thermotolerance of this species (up to 80°C) has been the subject of much controversy. This review is focused on the thermal adaptation of this worm regarding molecular data relative to its extracellular matrix and life history traits.

Utilization Of Dried Distillers Grains For Developing Beef Heifers, J. L. Martin, Andrea S. Cupp, Richard J. Rasby, Z. C. Hall, Richard N. Funston

Department of Animal Science: Faculty Publications

A 2-yr study was conducted at 2 locations to determine if supplementing beef heifers with dried distillers grains (DDG) as an energy source affected growth or reproduction. Spring-born crossbred heifers (n = 316) were blocked by age or sire and age and assigned randomly to DDG or control (dried corn gluten feed, whole corn germ, urea) supplement. Heifers received prairie hay in amounts sufficient for ad libitum intake and 0.59% of BW DDG or 0.78% of BW control supplement (DM basis). Supplements were formulated to be isocaloric, but protein degradability differed. Supplemental undegradable intake protein intake from DDG averaged 267 …

Investigating The Role Of Transcription Factor Ap-2�� In Reproduction, Anne Rachelle Howlett

Undergraduate Honors Capstone Projects

The proper formation of gametes is critical for the propagation of species and for the fertility of the individual. The molecular pathways involved in gamete formation remains elusive, therefore, identification of genes involved is an important prerequisite to further our understanding of reproduction. This research will improve infertility treatments and prevention methods in animals and humans. We created mutants that lacked AP-2�� transcription factor after the mouse had entered meiosis and initiated folliculogenesis. The AP-2�� mutants were still fertile and phenotypically similar to normal mice that expressed AP-2�� transcription factor. We also produced mutants that lacked AP-2�� transcription factor during …

Adding To The Reproductive Biology Of The Parthenogenetic Oribatid Mite, Archegozetes Longisetosus (Acari, Oribatida, Trhypochthoniidae), Michael Heethoff, Michael Laumann, Paavo Bergmann

Turkish Journal of Zoology

The oribatid mite, Archegozetes longisetosus, serves as a chelicerate model organism due to its relatively short life cycle and ease of laboratory culturing. It is a parthenogenetic species and all cultures recently used in different laboratories are descendants of a single female collected in 1993. While aspects of its developmental and functional biology have been published, knowledge of its reproductive rate and reproductive system is meager, and data on its life history are contradictory. Herein, we present the gross morphology of the reproductive system as obtained by SEM techniques and X-ray synchrotron microtomography, a new tool for studying mite anatomy. …
