Validating Body Condition Indices As Indicators Of Individual Quality: Does Condition Explain Intraspecific Variation In Reproductive Success And Survival Among Crimson Finches (Neochmia Phaeton)?
Body condition is expected to reflect individual quality because high quality individuals should be better at acquiring and using resources, resulting in higher fitness. However, the hypothesis that condition indices are meaningful indicators of individual quality has been questioned. I monitored a …

Effects of Variety, Harvest Moisture and Drying Air Temperature on the Wet Milling Characteristics of Yellow Dent Corn
… moisture and drying air temperature on twelve quality factors related to the millability of corn. A split-split plot experimental design was used to evaluate the effects. Variety was found to significantly influence the measurement of each individual quality factors among the varieties. …

Female Ornamentation in the American Robin
… investment in offspring and variation in female quality are high. I investigated this in the American robin (Turdus migratorius), a socially monogamous species with bi-parental care and variable female ornamentation. Female robins display conspicuous red breast plumage, bright yellow bills, and …

Reproductive Decisions in American Robins (Turdus Migratorius): Relationships Among Paternity Allocation, Parental Care, Plumage Variation, and Mate Choice
… effort has been devoted to examining how individual ecological and evolutionary factors shape breeding decisions in birds, but we are only beginning to address how these factors can interact to shape behavioral outcomes, particularly in species with overlapping broods. In my dissertation, …

The Ethical Justification of Increasing Awareness of Preventive Medicine among Healthcare Professionals, Patients and the General Public in the United States
… high rate of preventable diseases and increase individual quality of life. The first step of reintroducing preventive medicine is to educate the healthcare professionals on the importance of practicing preventive medicine in its combined form. Healthcare professionals are then responsible for …

Simultaneous process control of several independent quality variables
A method for multivariate quality control with the dual objectives of providing a true level of sampling error probabilities for the joint control of several quality variables while also giving problem diagnoses for the quality variables individually. The method is comprised of an afine …

Developing Interpretable Data Mining Frameworks for Addressing Biomedical Challenges in Genomics and Imaging
… Given the impacts of these conditions on individual quality of life and healthcare systems worldwide, it is imperative to develop a comprehensive set of computational methods for studying and detecting these diseases. This dissertation highlights the need for accessible and interpretable …

Corticosterone as a mediator of the tradeoff between survival and reproduction
… corticosterone, however, appears to reflect quality, with greater baseline levels associated with greater survival and reproduction. I then explore the relationship between corticosterone and reproduction at a finer scale, using both correlative and experimental approaches. Individual …

Ecological and molecular basis of differential resource use in populations of burying beetles Nicrophorus vespilloides
… which costly competition can be avoided is via individual specialisation, i.e., the persistence of specialised individuals within a generalist population that utilise a smaller subset of the entire population’s resource base. This could occur through the evolution of genetic morphs that …

Indirect effects of agricultural intensification on tree swallow (Tachycineta bicolor) foraging behaviour, body condition, and physiology
… a higher body condition than did younger individuals and males, respectively. Measures of physiology (i.e. total antioxidant counts and oxidative damage) in both adult and nestling swallows were primarily driven by temporal changes in insect biomass and abundance. Similarly, adult body …

Unravelling the ecological trade-offs in behavioural and physiological sexual traits
… environments throughout their lives. Therefore, individuals that are able to plastically adjust their behaviour to the current environment, are able to maximise their fitness. These behavioural adjustments are particularly important where there are trade-offs between investment in different …
