Investigating Meter Scale Topographic Variation As A Factor Of Monterey Pine (Pinus Radiata) Growing Conditions At Kenneth Norris Rancho Marino Reserve, Cambria, Ca, William J. Meyst
Natural Resources Management and Environmental Sciences
Endemic Monterey pine (Pinus radiata) is limited to three locations in California due to its unique ecological requirements. This project was conducted to investigate spatial growth patterns ofMonterey pine over complex ground surfaces. The coastal hills of Rancho Marino Reserve, Cambria, were surveyed using four 150-m transects to quantify and record ground surface features and growing conditions ofMonterey pine. Changes in elevation of each transect were measured using an Abney level. Linear ground surfaces were found at 86% (344 of 400) of survey nodes. Convex ground surfaces were found at 10.5% of survey nodes (42 of 400). Of …
Photosynthetic Thermal Tolerance And Recovery To Short Duration Temperature Stress In Desert And Montane Plants: A Comparative Study, David William Gallagher
Photosynthetic Thermal Tolerance And Recovery To Short Duration Temperature Stress In Desert And Montane Plants: A Comparative Study, David William Gallagher
Master's Theses
- Climate change models predict an increase in frequency and amplitude of extreme weather events, including heat waves. To better predict how the composition and distribution of plant assemblages might respond to these changes in temperature, it is important to understand how species currently respond to these extremes. Photosynthetic thermal tolerance (T25)and photosynthetic recovery (RT25) were quantified in 27 species. We also studied the relationships between T25, RT25 and leaf mass per area (LMA). Leaf temperature was also monitored in the field.
- Leaves used in this study were collected from two distinct …
Optimization Of Growth Parameters For Algal Regrowth Potential Experiments, Chadwick D. Boggess
Optimization Of Growth Parameters For Algal Regrowth Potential Experiments, Chadwick D. Boggess
Master's Theses
Water cost is one of the key deterrents in making algal biofuels a feasible alternative to traditional petroleum fuels. Research into recycling of algal media was conducted in a laboratory setting at the California Polytechnic State University in San Luis Obispo. A growth assay was created to allow for algal cultures, specifically Ward’s Chlorella sp., to proliferate in sealed culture vessels. Bold’s Basal Medium (BBM) was selected as the media due to its extensive use with freshwater algal strains. However, this medium can limit algal growth through nutrient limitation and it became necessary to augment the original recipe. 50mM …
Investigation Of Chromosome Size Effect On The Rate Of Crossovers In The Meiotic Yeast Saccharomyces Cerevisiae, Lanie Maria Galland
Investigation Of Chromosome Size Effect On The Rate Of Crossovers In The Meiotic Yeast Saccharomyces Cerevisiae, Lanie Maria Galland
Master's Theses
Meiosis is a specialized type of cell division characterized by a single round of DNA replication and two rounds of chromosome segregation, ultimately resulting in four haploid cells. During meiosis I, chromosomes align and reciprocal recombination results in the formation of a crossover, creating the tension required to properly segregate homologs during the first round of meiosis.
Two mechanisms involved in regulating the occurrence of crossing over are assurance and interference. Crossover assurance describes the phenomenon that at least one crossover will form between each pair of homologous chromosomes during prophase I. Crossover interference, on the other hand, describes the …
The Role Of Sirtuin Inhibitors On The Proteomic Responses Of The Mussels Mytilus Galloprovincialis And Mytilus Trossulus To Menadione Induced Oxidative Stress, Hayley C. Chilton
The Role Of Sirtuin Inhibitors On The Proteomic Responses Of The Mussels Mytilus Galloprovincialis And Mytilus Trossulus To Menadione Induced Oxidative Stress, Hayley C. Chilton
Master's Theses
Global climate change imposes physiological constraints on marine ecosystems that can alter the distribution of intertidal organisms. In one such instance, the native cold-adapted mussel Mytilus trossulus is being replaced along its southern range by the invasive warm-adapted Mytilus galloprovincialis. These blue mussels occur throughout rocky intertidal zones where they are subjected to greatly varying environmental conditions known to induce oxidative stress. We hypothesize that while under acute stress, related Mytilus congeners undergo a shift in redox potential from NADH-fueled respiratory pathways to pathways producing NADPH as a way to decrease the production of reactive oxygen species (ROS) and …

The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez
The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez
Animal Science
Understanding the efficiency and digestibility of dietary nutrients in dairy heifers is essential for minimizing costs and environmental impacts of the dairy industry. The objective of this study was to interpret the effects of manipulating rumen-degradable protein (RDP) in a precision feeding system. Eight Holstein ruminally cannulated heifers (14.6 ± 0.1 mo of age, and 386 ± 9.1 kg of weight) were randomly assigned to 2 forage levels: HC (25% forage) and LC (75% forage) and to a degradable protein sequence [0% degradable protein from urea U, 100% casein C (no urea treatment U0); 33% U, 67% C …

Central Coast Groundfish Species And Fillet Identification Manual, Robbie Milla
Central Coast Groundfish Species And Fillet Identification Manual, Robbie Milla
Agricultural Education and Communication
The purpose of this project was to create a manual that would aid fishermen and fish consumers in the successful identification of various groundfish species and their fillets. The manual was crafted with quality photographs to give the viewer a vivid depiction of the targeted groundfish species. The images were taken to specifically target the identification characteristics of each fish species. It was the hope of the author to educate anyone who was interested in the groundfish fishery. The manual includes: basic groundfish regulations, groundfish species identification, and groundfish fillet identification.
