Size Matters: Linkage Between Bromeliad Traits And The Spider Communities They Host In A Disturbed Habitat, Alesandra Fairchild

Ecuador: Comparative Ecology and Conservation

Bromeliads are a plant group that have been praised for their ability to create unique microhabitats, hosting an abundant and diverse faunal community due to their unique structural characteristics. Unfortunately, as deforestation rates rise, this plant group is at risk of decreasing in both abundance and diversity, which puts their associated organisms at risk of losing essential habitat (e.g. spiders). In this study, the effect of bromeliad structural characteristics and forest disturbance was assessed in a mature and secondary forest by classifying bromeliad abundance by forest type, characterizing forest structure, and by analyzing spider abundance and diversity based on these …

Community Partnerships To Address Social Determinants Of Health Among Older Adults, Cory Bolkan, Raven Weaver, Cheryl Eschbach, Erik Geissal, Breanne Wise-Swanson

Journal of Human Sciences and Extension

Focusing on social determinants of health (SDOH) among older adults is key to addressing health disparities, maintaining independence in their homes/communities, improving health outcomes, and avoiding high-cost institutional care. While primary care settings are equipped to meet older adults’ physical health needs, the network of Area Agencies on Aging (AAA) is designed to meet social needs (e.g., transportation, nutrition, caregiver support). Yet, cross-sector community partnerships between AAAs and primary care are rare. This article shares an evaluation of one such partnership, where SDOH screenings were routinely implemented in primary care, yielding social prescribing and direct referral to AAA’s support services. …

Effects Of Provisioning On Two Species Of Rock-Wallaby (Petrogale Mareeba And Petrogale Assimilis) In North Queensland, Australia, Eve Oliker

Australia: Rainforest, Reef, and Cultural Ecology

Provisioning, the act of providing food, water, or shelter to wild animals, can lead to habituation, resulting in changes in behavior, abundance, and distribution (Newsome & Rodger, 2008). In North Queensland, a colony of Mareeba rock-wallaby (Petrogale mareeba) at Granite Gorge has been provisioned for over 45 years, mainly through direct hand-feeding, while a group of allied rock-wallaby (Petrogale assimilis) in Magnetic Island has experienced shorter and less consistent provisioning. This study investigated whether long-term provisioning causes more severe behavioral changes, higher aggression, and larger aggregation sizes. Approximately one week was spent observing each population. Scan sampling was utilized to …

Bone Mineral Density Of Willow Ptarmigan (Lagopus Lagopus) As A Potential Taphonomic Factor In Skeletal Part Attrition, Frank J. Dirrigl Jr., Samuel R. Buchanan

School of Integrative Biological & Chemical Sciences Faculty Publications

Agents of taphonomy can bias skeletal parts and the frequency of bones in archaeological sites. An important factor to consider is the possible effect of bone density-mediated attrition on archaeornithological assemblages. We scanned willow ptarmigan (Lagopus lagopus) specimens using a Lunar iDXA and an enCcore small animal body add-on to develop a rank-order scheme based on the volumetric bone mineral density (vBMD) of skeletal parts. Our results identified the tibiotarsus and femur to be the least dense bones, while carpometacarpus, 3rd digit, and coracoid were the densest. This novel scheme allowed us to evaluate a sample of 22 …

Hooks For Four-Dimensional Ecology Education (4dee) Teaching With Differing Audiences Of Nonmajors, Sara E. Scanga, Vikki L. Rodgers, Loren B. Byrne, Justin R. St. Juliana, Jon M. Honea, Erica S. Tietjen, George Middendorf

Arts & Sciences Faculty Publications

Nonmajors (i.e., undergraduate students not majoring in the natural sciences) constitute a majority of United States college graduates and are a large potential audience for courses with ecology content. However, nonmajors may be unmotivated to learn about ecology because they perceive it to be uninteresting and irrelevant to their everyday lives or career goals. Although the Four-Dimensional Ecology Education (4DEE) framework can be adapted for nonmajors courses as a starting point to improve student engagement, we suggest that nonmajors ecology instructors also use ecology hooks as effective gateways to 4DEE that will motivate and deepen student learning. Selecting and developing …

Adipokines Mediate Fat-To-Ovary Communication To Regulate Oogenesis, Adipocyte Size, And Lipid Storage In Drosophila Melanogaster, Chad Herbert Simmons

Theses and Dissertations

Humans have complex signaling pathways that allow them to store and expend energy based on nutritional quality and availability. Inter-organ signaling is used to communicate nutrient availability between organs based on nutritional needs and the rate of cellular division. Our main overarching question is to investigate how fat-derived signals affect adipocyte morphology and the maintenance of stem cells in the ovary. While signaling pathways, like insulin and mTOR, and some adipokines that are involved in inter-organ nutrient sensing have been identified, the exact nutrient reliant mechanisms of stem cell maintenance are not completely understood. Using Drosophila melanogaster as a model, …

Children’s Nutrition Research Center Staff Publications

Aim: To assess the risk for impaired insulin homeostasis as a function of menopause-related factors and gut microbiota dysbiosis in non-diabetic, post-menopausal women.

Materials and methods: Baseline data (n = 175 women) from the Microbiome and Insulin Longitudinal Evaluation Study (MILES) were used, including insulin and dysglycaemia indices calculated from a 2-h oral glucose tolerance test, untargeted peripheral metabolomics, targeted peripheral short chain fatty-acid levels and faecal bacterial microbiota surveyed by whole-metagenomic sequencing.

Results: After adjustment for covariates, menopause age < 50 years and use of hormone replacement therapy (HRT) were associated with lower Matsuda et al. insulin sensitivity index levels (β = -0.232, confidence interval (CI) = [-0.450, -0.014] and β = -0.275, CI = [-0.444, -0.107], respectively) but not pre-menopausal gynaecologic surgery. Pre-menopausal gynaecologic surgery was significantly associated with faecal microbiota beta diversity driven by a relative increase in diabetogenic Ruminococcus gnavus and Clostridium species and a decrease in protective Alistipes species and Akkermansia muciniphila relative abundances. A reduction in two glycerophospholipids in the plasmalogen class significantly statistically mediated an inverse association between gynaecologic surgery before menopause and insulin sensitivity.

Conclusions: Menopause age and history of HRT are more strongly associated with insulin resistance than gynaecologic surgery before menopause. However, …
