Faculty, Staff and Student Publications

Experiencing homelessness in infancy has been linked to negative physical and mental health outcomes. Parental well-being and the parent-infant relationship can also be negatively impacted by experiencing homelessness. While numerous parent-based infant mental health programs have been identified by a recent review, the goal of this study was to further determine the extent to which these existing programs were developed and/or examined with at-risk populations such as families experiencing homelessness. Out of 60 programs identified by Hare et al., in press, only three had been implemented specifically in shelter settings with infants 0-12 months (Parent-Infant Psychotherapy, New Beginnings, and My …

The Effects Of Aerobic Exercise To Improve Depression In Overweight Adults, Curtis Lura

Master of Science in Nursing Family Nurse Practitioner

Overweight/obese adults are at an increased risk for both physical and mental comorbidities (CDC, 2019). Depression is a common comorbidity in those that are obese (CDC, 2019) and the standard of care currently to treat depression may increase the risk of physical comorbidities because weight gain is a common side effect of antidepressants (Hall-Flavin, 2018). The aim of this capstone research paper is to present evidence that an aerobic exercise regimen can be a valid treatment option for depression.

The Nature And Extent Of Algal Symbiosis In Three North American Ranids, Zachary T. Vegso

Cal Poly Humboldt theses and projects

The symbiotic relationship between the chlamydomonad green alga Oophila amblystomatis and embryos of certain amphibian species is often presumed to be mutualistic. However, the existence of a mutualism has only been experimentally tested and established in two closely related ambystomatid salamanders. These experiments showed a positive correlation between intracapsular algal density and embryonic growth, survival, hatching synchrony, and hatchling body size. Oophila has been documented within egg capsules of a growing number of amphibian species, including several frogs in the family Ranidae. However, the nature and extent of this relationship remains unclear. Ranid eggs are better oxygenated than ambystomatid eggs, …

Scale And Habitat Effects On Measurement Of Streptomyces Biogeography And Biodiversity, Terilyn A. Stoflet

Cal Poly Humboldt theses and projects

Bacteria in the genus Streptomyces are detected in most soils around the world, as well as on and in seeds, plants, animals, insects and the wind. Currently, more than 700 valid species of Streptomyces have been identified worldwide. Streptomyces produce the majority of antibiotics, antivirals and antifungals, as well as important agricultural bioactive molecules due to their unique genetic capabilities. Their distinct genetic abilities allow them to produce an unlimited amount of biosynthetic gene clusters, or BGC’s. Although many compounds come from Streptomyces, scientists have not discovered the biogeographic patterns of this genus. The biogeography of Streptomyces is a …

This study examines the intersectionality of athletic and ethnic identities and their influence on food choices among college-aged active individuals. Using the Multigroup Ethnic Identity Measure (MEIM), Athletic Identity Measurement Scale (AIMS), and Athlete Food Choice Questionnaire (AFCQ), this research explores how these identities impact nutritional attributes, usual eating practices, and performance-related food choices in a sample of 109 participants (58% female, mean age = 25.02 years) from diverse ethnic backgrounds. The hypothesis that a salient athletic identity combined with a salient ethnic identity would predict food choices prioritizing nutritional attributes was supported, suggesting that individuals with both identities salient …

Simulated Effects Of Postpartum Depression On Maternal-Infant Bonding: Mediated By Reward-Related Responses To Infant Facial Cuteness, Caitlin Harp

Cal Poly Humboldt theses and projects

Infant cuteness (facial cuteness in particular) is linked to evolutionary adaptations to motivate caretaking and protective behaviors (Kringelbach et al., 2008). Previous neuroimaging work has demonstrated that infant cuteness activates reward-related regions in the brain (Glocker et al., 2009) and behavioral work suggests that the reward value of cuteness is linked to maternal tendencies (Hahn et al., 2015). It is estimated that 15% of new mothers experience postpartum depression (PPD) (Wisner et al., 2013), which impacts the mesolimbic system and is linked to anhedonia (i.e., reduced ability to experience pleasure). Based on the above literature, this study used a simulated …

Barn Owls Exert Top-Down Effects On The Abundance And Behavior Of Rodent Pests, Katherine C. Larson

Cal Poly Humboldt theses and projects

Predators can exert top-down effects on their prey by direct consumption, by imposing risk of predation, or a combination of both. However, empirical evidence for these effects is mixed and inconsistent. Barn owls in agriculture present a system with attributes that should, according to theory, lead to strong top-down effects, but research is limited and the distinction between effects on prey abundance and behavior remains unresolved. Understanding the top-down effect of predators on pests is a cornerstone of integrated pest management and important where barn owls may contribute to the control of rodents on farms. Vegetation can mediate the top-down …
