Bovine Mammary Gland Biopsy Techniques, Veridiana L. Daley, Charles Dye, Sophie H. Bogers, R. Michael Akers, Francisco C. Rodriguez, John P. Cant, John Doelman, Peter Yoder, Karan Kumar, Dane Webster, Mark D. Hanigan

Animal and Food Sciences Faculty Publications

Bovine mammary gland biopsies allow researchers to collect tissue samples to study cell biology including gene expression, histological analysis, signaling pathways, and protein translation. This article describes two techniques for biopsy of the bovine mammary gland (MG). Three healthy Holstein dairy cows were the subjects. Before biopsies, cows were milked and subsequently restrained in a cattle chute. An analgesic (flunixin meglumine, 1.1 to 2.2 mg/kg of body weight) was administered via jugular intravenous [IV] injection 15-20 min prior to biopsy. For standing sedation, xylazine hydrochloride (0.01-0.05 mg/kg of body weight) was injected via the coccygeal vessels 5-10 min before the …

Using Clay Models To Measure Seasonal Predation On Eastern Red-Backed Salamanders, Emma Perry

Honors Program Theses and Projects

One of the many gaps we have in our knowledge of salamanders is that of predation. Most studies suggest that salamanders are eaten mainly by birds and snakes, but there are still several unanswered questions: What other types of animals tend to prey on salamanders? Is there any difference in predator type during different times of the year? In order to answer these questions, I studied predation on one particular species of salamander, Plethodon cinereus (eastern red-backed salamander). Models of the two primary color morphs of P. cinereus (striped and unstriped) were created using impressionable clay to determine types and …

The Impact Of Online Homework, Time On Homework, Gender, And Metacognition In Improving Student Achievement In Undergraduate Biology Courses, Donald Bishop Cook Jr

Doctoral Dissertations and Projects

This study sought to address a gap in the literature to determine whether a relationship exists between use of online homework and student achievement in undergraduate biology courses. Previous studies have examined other STEM courses, but few have considered biology. The purpose of the study was to determine whether homework grades in online homework systems can predict student achievement in introductory undergraduate biology courses. This study utilized a correlational analysis by multiple regression using archival data to determine whether final course grades in undergraduate biology courses can be predicted by grades on online homework, time spent on online homework, gender, …

Sex Determination By Morphological Measurements Of Young Rockhopper Penguins (Eudyptes Chrysocome) During The Crèche Phase, Virginia Morandini, Miguel Ferrer, Lynelle Perry, Marc Bechard

Raptor Research Center Publications and Presentations

To provide an easy and reliable work tool to identify the sex of Rockhopper Penguin (Eudyptes chrysocome) chicks, we weighed and measured 95 nestlings in the crèche phase during 24-31 January 2017 on the Falkland Islands, Argentina. Sex was subsequently determined using DNA analyses of blood from the same individuals. Significant differences were found in bill length (exposed culmen), bill depth and width, flipper length, and diagonal tarsus, but stepwise discriminant analysis showed bill length to be the best predictor for sex determination. Our model correctly classified 82.7% of males and 90.2% of females (overall correct classification 86.2%). …

Midguts, Microbes, And Mosquitoes: An Analysis Of The Microbiomes Of Aedes Aegypti And Aedes Albopictus, Flor Alicia Martinez

Theses and Dissertations

Experiment 1: Mosquito microbiomes are influenced by the environment and diets of mosquitoes. There is great variability within and among mosquito populations with few microbe inhabitants being well established among mosquitoes of similar species and environments. By understanding the potential variation in midgut microbiomes in lab and wild populations, we may assess the effect that microbiomes have on vector competency.

Experiment 2: Mosquito midgut microbes are essential for development and may influence the vector competency. Native and non-native strains of the midgut inhabitant, Cedecea, were introduced to laboratory colonies of Aedes aegypti and Aedes albopictus mosquitoes to help elucidate …

Molecular Fossils From Phytoplankton Reveal Secular Pco2 Trend Over The Phanerozoic, Caitlyn R. Witkowski, Johan W. H. Weijers, Brian S. Blais, Stefan Schouten, Jaap S. Sinninghe Damsté

Science and Technology Department Faculty Journal Articles

Past changes in the atmospheric concentration of carbon dioxide (PCO2) have had a major impact on earth system dynamics; yet, reconstructing secular trends of past PCO2 remains a prevalent challenge in paleoclimate studies. The current long-term PCO2reconstructions rely largely on the compilation of many different proxies, often with discrepancies among proxies, particularly for periods older than 100 million years (Ma). Here, we reconstructed Phanerozoic PCO2 from a single proxy: the stable carbon isotopic fractionation associated with photosynthesis (Ɛp) that increases as PCO2 increases. This concept has been widely applied to alkenones, but here, we …

Phylogenetics: A Catalyst For A Biophilic Revolution?, Holli N. Watne

Summit to Salish Sea: Inquiries and Essays

A biology framework in Environmental Education can inspire biophilia, the love for the complex array of lifeforms on this planet, in students. In this paper, a simple, multi-scaled phylogenetic tree is presented to express such a framework. When viewing life from a framework such as a phylogenetic tree, the human species is seen as just one part of something vastly complex. This view is contrasted to another framework, more anthropocentric in nature, that seems to be more typical in the developed world. Challenging students to view the role of humanity from a biocentric, rather than anthropocentric, framework can lead to …

Illuminating Endocrine Evolution: The Power And Potential Of Large-Scale Comparative Analyses, Maren N. Vitousek, Michele A. Johnson, Jerry F. Husak

Biology Faculty Research

Hormones are central mediators of genotype–phenotype and organism–environment interactions. Despite these important functions, the role of selection in shaping hormonal mediators of phenotype remains poorly understood. Thanks to decades of work by endocrinologists, circulating hormone levels have been measured in a diversity of organisms. Variation in other endocrine traits and mediators (e.g., receptor expression and binding globulins), and the hormonal response to standardized challenges (e.g., restraint, pharmacological challenges) are also increasingly measured in both captive and free-living populations. Large-scale comparative analyses of the multitude of available endocrine data represent a particularly promising approach to addressing the function and evolution of …
