Evaluating Mountain Lion Diet Before And After A Removal Of Feral Horses In A Semiarid Environment, Peter C. Iacono, Kathryn A. Schoenecker, Kezia R. Manlove, Pat J. Jackson, David C. Stoner

Wildland Resources Faculty Publications

Non-native species can affect ecosystems by influencing native predator-prey dynamics. Therefore, management interventions designed to remove non-natives may inadvertently lead to increased predation on native species. Feral horses are widely distributed throughout the arid parts of western North America. A growing body of research indicates that horses can be an important prey species to mountain lions in ecosystems where they overlap. In December 2020, the Bureau of Land Management removed 455 horses from the Delamar Mountains, Nevada, USA. We leveraged this management intervention to implement a before–after–control–impact study to test hypotheses about predation on horses and native ungulates. We predicted …

Instrumentation Failure In Adult Spinal Deformity Patients, David P Falk, Ravi Agrawal, Bijan Dehghani, Rohit Bhan, Sachin Gupta, Munish C Gupta

2020-Current year OA Pubs

In recent years, advances in the surgical treatment of adult spinal deformity (ASD) have led to improved outcomes. Although these advances have helped drive the development of deformity surgery to meet the rising volume of patients seeking surgical treatment, many challenges have yet to be solved. Instrumentation failure remains one of the most common major complications following deformity surgery, associated with significant morbidity due to elevated re-operation rates among those experiencing mechanical complications. The two most frequently encountered subtypes of instrumentation failure are rod fracture (RF) and proximal junctional kyphosis/proximal junctional failure (PJK/PJF). While RF and PJK/PJF are both modes …

A Non-Randomized Comparison Of Engagement And Outcomes For In-Person Versus Virtual Delivery Of The Partner2lose Weight Management Trial, Heather Johnson

All Publications

Objective: Existing behavioral weight management interventions produce clinically meaningful weight loss. The onset of the COVID-19 pandemic led to the quick transition of such interventions from in-person to virtual platforms. This provided a unique opportunity to compare engagement and outcomes for an in-person versus virtually delivered weight management intervention.

Methods: A non-randomized comparison of engagement and weight outcomes was performed between two cohorts who participated in a weight management intervention in person (N = 97) versus three who participated virtually via videoconference (N = 134). Various metrics of engagement were examined, including group class and individual phone call …

Light plays an essential role in a variety of physiological processes, including vision, mood, and glucose homeostasis. However, the intricate relationship between light and an animal's feeding behavior has remained elusive. Here, we found that light exposure suppresses food intake, whereas darkness amplifies it in male mice. Interestingly, this phenomenon extends its reach to diurnal male Nile grass rats and healthy humans. We further show that lateral habenula (LHb) neurons in mice respond to light exposure, which in turn activates 5-HT neurons in the dorsal Raphe nucleus (DRN). Activation of the LHb→5-HTDRN circuit in mice blunts darkness-induced hyperphagia, while inhibition …

India's Use Of Public-Private Partnerships To Promote Rapid Expansion Of Solar Electricity Facilities, Karen Consalo

Florida Journal of International Law

This Article will explore the use of PPPs to encourage the flow of private capital and expertise toward development of low-carbon, low-pollution, sustainable energy generation in India to achieve the country’s ambitious goal of creating 175 gigawatts of renewably sourced electricity by 2022. The lessons in India’s extensive use of PPPs to achieve such ambitious electricity goals should serve as a model for other governments to engage the private sector to successfully develop solar and other renewable energy projects with limited risk but with significant benefits for their citizens.

Estimation Of Herbage Intake Of High Producing Milking Cows Under Intensive Grazing With A Supplementary Feeding Method In Northern Japan, K Ohiai, K Sudo, T Ikeda, T Honma

IGC Proceedings (1977-2023)

The objective of this study was to estimate the herbage intake and to assess a supplementary feeding method for high producing milk cows under intensive grazing. Eight high producing milking cows were grazed rotationally on perennial ryegrass (Lolium perenne L) dominant mixed pasture and on meadow fescue (Festuca elatior L) dominant mixed pasture, changing rotation period and grazing area ccording to seasonal pasture growth rate. Pasture intakes were estimated to be about 2% of body weight by TDN requirements estimation of animals. A supplementary feeding method is examined to be proper for high producing milking cows under …

Selective Sheep Grazing In An Heterogeneous Wheatgrass Dominated Pasture Related To Stocking Rate, G L. Siffredi, M A. Brizuela, M S. Cid, C Cangiano

IGC Proceedings (1977-2023)

It has been hypothesized that patch and community selection are driven by forage quality and/or quantity. We assess the relationship between vegetation characteristics and community and patch selection by sheep under continuous grazing at different stocking rates in an heterogeneous pasture. Our results suggest that when communities strongly differed in nutritive value sheep recurrently select the higher quality community in spite of its low biomass. However, sheep do not completely exclude the poorer quality community, generating a patchy vegetation pattern.

Comparison Of Yield, Forage Quality And Persistence Of 11 Grasses Grown With Irrigation In A Semi-Arid Climate, D E. Glover, G A. Kielly, R H. Cohen, P G. Jefferson

IGC Proceedings (1977-2023)

Nutritive quality of many grass species used for forage in the Northern Great Plains of Canada and the United States is not well documented, especially at different maturity stages. This study compared agronomic and forage quality characteristics of eleven grasses common to Saskatchewan. Botanical separation and quality analysis was undertaken at three growth stages. Meadow Brome (Bromus riparius), Russian Wildrye (Psathyrostachys juceus) and Altai Wildrye (Elymus angustus) were shown to have high leaf to stem ratios which corresponded with high protein levels. Separations showed persistence of Reed Canarygrass (Phalaris arudinaceus), Creeping Foxtail …

Trace Mineral Status Of Beef Cattle Grazing Semiarid Rangelands Of North Mexico, J R. Kawas, G T. Armienta, E Olivares, O Torress, J J. Kawas, F Garza

IGC Proceedings (1977-2023)

Trace mineral concentrations of soil, forage and serum of range cattle of the northeast Mexico state of Nuevo Leon were determined in both wet and dry seasons of 1992. For each season, collections were made at twenty-four ranches within eleven counties of three regions. A total of 220 soil, 680 forage and 220 blood samples were collected and analyzed. No differences (P<0.05) between regions were obtained for Zinc (28.0 to 34.9 ppm) or Copper (4.4 to 5.4 ppm). Molybdenum concentrations were greater in the northern (2.1 ppm) than in the central (1.6 ppm) or southern (1.5 ppm) regions. Considering the critical levels in forages for Zinc (30 ppm) and Copper (10 ppm) reported by the National Research Council (1984), Zinc concentrations may be marginally deficient, whereas Copper concentrations were deficient in all three regions, in both seasons, and in grasses and woody species.

IGC Proceedings (1977-2023)

The effects on the net profit and total milk production were compared using two levels of grain supplementation and forage-only feeding in a program of seasonal dairying in South Louisiana using management intensive grazing. Treatments were 8 kg grain, 4 kg grain, and 0 grain supplementation. Annual ryegrass (Lolium multiflorium) and clovers (Trifolium incarnatum, and T. Alexandrinum) were grazed intensively with 51 multiparous Jersey and Holstein cows in mid-lactation in 1993-1995. Milk production, milk fat, milk protein, and blood urea nitrogen were measured. Milk and protein models were all highly significant for all classes. Daily milk …

Influence Of Sheep And Goats On The Natural Succession, H D. Matthes, S Demise, M Schubert, H Mohring

IGC Proceedings (1977-2023)

A study was conducted to examine the effect of extensively-grazed pasture on the botanical composition. The trails were carried out in the year 1992 to 1995. For the study different breeds of sheep with the stocking rate of 30 sheep with their lambs / 2.6 ha were used. For the mixed-grazing a ratio of 20 sheep and 10 goats with their lambs / 2.6 ha were used. It is not possible to control all problem species with the help of sheepgrazing only. In contrast to that, it was concluded that goats grazed off all problem species quite effectively. Botanical composition …

Student Exposure To Andhii Improves Confidence With Applying The Nutrition Care Process, Casey Colin, Tad Campbell, Michel Harris, Avalon Mustafa, Lindsay Woodcock

Journal of Dietetic Education

The objective of this study was to explore if using ANDHII improves NCP confidence and documentation quality. This quasi-experimental trial was conducted with n = 43 undergraduate dietetic students. NCP confidence was measured before and after a traditional case study, and after an ANDHII case study. Documentation quality was measured using a validated quality audit tool. Confidence increased from time 1 to time 2 (p = 0.008), and from time 2 to time 3 (p = 0.003). Documentation quality was higher for the ANDHII documentation compared to the non-ANDHII documentation (p < 0.001) but lower when compared to the traditional ADIME (p = 0.03). Familiarizing students with ANDHII improved NCP confidence. Opportunities exist to improve ANDHII functionality and positively impact documentation quality.

Can Gpa And Degree Type Predict Success On The Entry-Level Registration Examination For Dietitians?, Sunitha Zechariah, Jennifer Doley, Nicole Moore, Raymond Chong

Journal of Dietetic Education

Purpose: Although program directors consider several measures when assessing dietetic program applicants, grade point average (GPA) is often the most highly weighted. However, its ability to predict success in the entry-level registration examination for dietitians (RD exam) is unknown. Our objective was to determine how well GPA predicted first-time success in the RD exam. Methods: We conducted a retrospective review of the associations among academic variables: pre-admission GPA (Overall- GPA), didactic program in dietetics GPA (DPD-GPA), and the type of degree (bachelor's versus master’s) with first-time RD exam scores across seven cohorts from three DI programs (N = 408). Results: …

Registered Dietitian Nutritionists’ Knowledge, Confidence, And Experiences With Treating Trafficked Individuals: A Call For Interprofessional Continuing Education, Christen C. Cooper, Lydia Mcroberts

Journal of Dietetic Education

Background: Victims of human trafficking (HT) frequently face malnutrition, dehydration, low food security, and infections. When identified, victims of HT are normally treated with interprofessional team (IPT) care that often excludes Registered Dietitian Nutritionists (RDNs). Although RDNs are trained to treat these conditions, they may lack knowledge, confidence, and skills, for working with this population, as well as the opportunities to work on such IPTs. To date, no study has explored RDNs’ knowledge of or work with individuals who are trafficked. Objective: To explore RDNs’: HT knowledge, confidence in the ability to work with victims of HT, and barriers to …

Learning At Diabetes Camp: Experiential And Interprofessional Opportunities For Dietetics Students, Mallory Mount, Mary Kathryn Gould

Journal of Dietetic Education

Diabetes camp is helpful in providing hands-on learning experiences and interprofessional learning opportunities through immersive experiences. Currently, there is little research comparing the changes in knowledge and perception during experiential learning in dietetics students at a residential diabetes camp. This longitudinal qualitative case study explored the knowledge, perceptions, confidence, and empathy gained by four dietetics students during experiential learning at the camp. Qualitative research methods (interviews, observations, "photovoice," journals, and focus groups) were used to explore and understand participants’ experiences of hands-on involvement with type one diabetes, and what they learned at camp that cannot be learned in a classroom. …

Barriers To Implementation Of Practice Guidelines In Heart Failure, Mary Geisenhof

DNP Projects

In 2022, the most recent guidelines for care of the patient with heart failure (HF) were released by the American Heart Association (AHA), the American College of Cardiology (ACC), and the Heart Failure Society of America (HFSA). In summary, this group did not recommend fluid restriction for patients with heart failure, unless they are in the end stages of heart failure, and only if fluid restriction may be beneficial (Heidenreich et al., 2022). Despite this recommendation, some providers and nurses continue to restrict fluids. The aim of this DNP project, therefore, was to analyze barriers to implementation of best practices …

Addressing The Importance Of Counseling For Adolescents Experiencing Homelessness Participating In Homeless Assistance Programs, Justin Corey Singleton

Electronic Theses and Dissertations Archive

The number of youths experiencing homelessness has increased significantly over the years. The mental health of youth experiencing homelessness is of great concern due to the high disparity rates of depression, anxiety, and substance use disorders in comparison to their peers that have a home. A positive support factor can help youth by interceding during a time of need. Identifying that support can be challenging for youth as their cognitive functioning is often deregulated due to untreated mental illnesses. Concepts from the Ecobiodevelopmental Theory address the importance of counseling services assisting youth with establishing healthy and supportive outcomes by identifying …

The Role Of Biological Plasticity In Model-Based Translational Research, Jessica A. Bolker

Faculty Publications

Reports of low replicability and translatability of biomedical research have called the value of animal models into question. The problems are real, but abandoning animal research is not the solution. Rather, improving the translatability of model-based research requires attention to relevant differences between humans and models, and to attributes of the models themselves that are essential to both robust science and effective translation. One is biological plasticity, the responsiveness of individual organisms to complex and variable environments. Though under-represented in model systems (for both historical and practical reasons), plasticity is central to human biology. While there are good reasons to …

Hyaluronan Mediates Cold-Induced Adipose Tissue Beiging, Xi Chen, Yifan Wang, Huiqiao Li, Yanru Deng, Charlise Giang, Anying Song, Yu'e Liu, Qiong A Wang, Yi Zhu

Faculty, Staff and Students Publications

Adipose tissue beiging refers to the process by which beige adipocytes emerge in classical white adipose tissue depots. Beige adipocytes dissipate chemical energy and secrete adipokines, such as classical brown adipocytes, to improve systemic metabolism, which is beneficial for people with obesity and metabolic diseases. Cold exposure and β3-adrenergic receptor (AR) agonist treatment are two commonly used stimuli for increasing beige adipocytes in mice; however, their underlying biological processes are different. Transcriptional analysis of inguinal white adipose tissue (iWAT) has revealed that changes in extracellular matrix (ECM) pathway genes are specific to cold exposure. Hyaluronic acid (HA), a non-sulfated linear …
