Cool-season grass species (18) and cultivars (85) were evaluated for use in seeded grasslands in the tallgrass prairie and shortgrass steppe ecoregions of the central United States at the test locations of Ithaca and Sidney, NE, respectively. Both native and introduced grasses were evaluated in sward trails. Significant differences existed among species and cultivars for all traits evaluated except for in vitro dry matter digestibility (IVDMD) among cultivars within species at Sidney. The grasses that had the best establishment, persistence, and forage yields in the Ithaca trial were introduced wheatgrass (Thinopyrum) and bromegrass (Bromus) species. At …

Co-Targeting Strategy For Precise, Scarless Gene Editing With Crispr/Cas9 And Donor Ssodns In Chlamydomonas, Soujanya Akella, Xinrong Ma, Romana Bacova, Zachary P. Harmer, Martina Kolackova, Xiaoxue Wen, David A. Wright, Martin H. Spalding, Donald P. Weeks, Heriberto Cerutti

School of Biological Sciences: Faculty Publications

Programmable site-specific nucleases, such as the clustered regularly interspaced short palindromic repeat (CRISPR)/ CRISPR-associated protein 9 (Cas9) ribonucleoproteins (RNPs), have allowed creation of valuable knockout mutations and targeted gene modifications in Chlamydomonas (Chlamydomonas reinhardtii).

However, in walled strains, present methods for editing genes lacking a selectable phenotype involve co-transfection of RNPs and exogenous doublestranded DNA (dsDNA) encoding a selectable marker gene. Repair of the dsDNA breaks induced by the RNPs is usually accompanied by genomic insertion of exogenous dsDNA fragments, hindering the recovery of precise, scarless mutations in target genes of interest. Here, we tested whether co-targeting two …

Targeted Manipulation Of Abundant And Rare Taxa In The Daphnia Magna Microbiota With Antibiotics Impacts Host Fitness Differentially, Reilly O. Cooper, Janna M. Vavra, Clayton E. Cressler

School of Biological Sciences: Faculty Publications

Host-associated microbes contribute to host fitness, but it is unclear whether these contributions are from rare keystone taxa, numerically abundant taxa, or interactions among community members. Experimental perturbation of the microbiota can highlight functionally important taxa; however, this approach is primarily applied in systems with complex communities where the perturbation affects hundreds of taxa, making it difficult to pinpoint contributions of key community members. Here, we use the ecological model organism Daphnia magna to examine the importance of rare and abundant taxa by perturbing its relatively simple microbiota with targeted antibiotics. We used sublethal antibiotic doses to target either rare …

Interactions With Soil Fungi Alter Density Dependence And Neighborhood Effects In A Locally Abundant Dipterocarp Species, R. Max Segnitz, Sabrina E. Russo, Kabir G. Peay

School of Biological Sciences: Faculty Publications

Seedling recruitment can be strongly affected by the composition of nearby plant species. At the neighborhood scale (on the order of tens of meters), adult conspecifics can modify soil chemistry and the presence of host microbes (pathogens and mutualists) across their combined canopy area or rooting zones. At local or small spatial scales (on the order of one to few meters), conspecific seed or seedling density can influence the strength of intraspecific light and resource competition and also modify the density-dependent spread of natural enemies such as pathogens or invertebrate predators. Intrinsic correlation between proximity to adult conspecifics (i.e., recruitment …

Factors Influencing Survival Rates Of Pronghorn Fawns In Idaho, Brett R. Panting, Eric M. Gese, Mary M. Conner, Scott Bergen

United States Department of Agriculture Wildlife Services: Staff Publications

Pronghorn (Antilocapra americana) occur throughout western North America. In Idaho, USA, following intensive hunting to reduce crop depredations in the late 1980s, pronghorn populations have not rebounded to desired levels. Because neonatal survival in ungulates is one factor limiting population growth, we evaluated cause‐specific mortality and the influence of intrinsic and extrinsic factors on survival rates of 217 radio‐collared pronghorn fawns across 3 study areas in Idaho during 2015–2016. For intrinsic variables, we determined the sex and body mass index (BMI) for each fawn. For extrinsic variables, we determined the abundance of predators and alternate prey, estimated the …

Powassan Virus Experimental Infections In Three Wild Mammal Species, Nicole M. Nemeth, J. Jeffrey Root, Airn E. Hartwig, Richard A. Bowen, Angela M. Bosco-Lauth

United States Department of Agriculture Wildlife Services: Staff Publications

Powassan virus (POWV) is a tick-borne virus maintained in sylvatic cycles between mammalian wildlife hosts and ticks (primarily Ixodes spp.). There are two currently recognized lineages, POWV-lineage 1 (POWV-L1) and deer tick virus (DTV; lineage 2), both of which can cause fatal neurologic disease in humans. Increased numbers of human case reports in the northeastern and north central United States in recent years have fueled questions into POWV epidemiology. We inoculated three candidate wildlife POWV reservoir hosts, groundhogs (Marmota monax), striped skunks (Mephitis mephitis), and fox squirrels (Sciurus niger), with either POWV-L1 or DTV. …

Measuring Adrenal And Reproductive Hormones In Hair From Southern Beaufort Sea Polar Bears (Ursus Maritimus), Marilize Van Der Walt, Lorin A. Neuman-Lee, Patricia A. Terletzky, Todd C. Atwood, Eric M. Gese, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

Polar bears (Ursus maritimus) use sea ice to access marine mammal prey. In Alaska’s Southern Beaufort Sea, the declining availability of sea ice habitat in summer and fall has reduced opportunities for polar bears to routinely hunt on the ice for seals, their primary prey. This reduced access to prey may result in physiological stress with subsequent potential consequences to reproductive function (physiological changes that accompany reproduction), which can be measured via reproductive hormones. Hormone concentrations in hair can be used as a minimally invasive alternative to serum concentrations, which must come from animal captures. Hair samples also …

Dietary Flexibility Of Wood Storks In Response To Human-Induced Rapid Environmental Change, Betsy A. Evans, Jessica A. Klassen, Dale E. Gawlik

United States Department of Agriculture Wildlife Services: Staff Publications

Human-induced rapid environmental change (HIREC) has altered landscape processes and negatively impacted many species globally. Some of the most dramatic changes have been in wetlands where flows have been disrupted, and new wetlands have been created to retain runoff. In response to disrupted natural wetland conditions, Wood Stork (Mycteria americana) populations in South Florida have significantly declined over the past several decades. Despite the well-documented sensitivity of Wood Storks to natural wetland conditions, Wood Storks are often observed foraging in roadside created wetlands; however, the availability of prey in created wetlands is currently unknown. We sampled natural and created wetlands …

However, diabetes education is not very well-supported in the office setting due to the providers’ limited time per patient. However, with the aid of technology-based intervention, patients can be more supported and educated, leading to better T2DM control.

Aims: The purpose of this scholarly project was to evaluate the effectiveness of diabetes education through tele-coaching in patients with T2DM for improved self-care and clinical outcomes, including hemoglobin A1c (A1c) and body mass index (BMI).

Method: A mixed-method, single …

The Future Of Leadership Training: An Immersive Web-Based Program Enhancing Nurse’S Critical Soft Leadership Skills In New Healthcare Contexts, Nina Vaid Raoji

Yale School of Nursing Digital Theses

As the care of health shifts to a more decentralized model of care, it essential that the role of nursing facilitates new paths to meeting patients and communities where they are in the context of their lives, forging new partnerships outside of the traditional health care setting, and focusing on advocating for collective upstream solutions (Pittman, 2020). However, this shift requires a set of skills that are not a focus of current nurse leadership training. These are Soft Leadership Skills: networking, communication, teamwork, and innovation/creativity, but not in the traditional sense of the terms (Rao, 2017). The goal of this …

Enhancing Harvester Safety And Traditional Food Access Through Participatory Mapping With The Ka’A’Gee Tu First Nation Of Kakisa, Northwest Territories, Neomi Jayaratne

Theses and Dissertations (Comprehensive)

Northern Canada has struggled with various systemic challenges based on Eurocentric ideologies, policies, and practices. A major challenge Indigenous communities face North of the 60^th parallel is their food security and sovereignty. Inuit, First Nation and Métis populations across the North experience 5 to 6 times higher levels of food insecurity compared to the National average (Food Secure Canada, 2020). These communities face concentrated levels of food system issues, which connect to other factors, such as, health and wellness, the supply chain of market foods, governance, a shift away from traditional foods, and the impacts of climate change. Climate …

Sucrose Solution Access Influences Intake Value In Rats, Adam Celejewski

Theses and Dissertations (Comprehensive)

Previous work has shown that non-deprived rats’ intake of a 4% sucrose solution increases over 24 h access periods if it is provided every 3 or 4 days (E3D or E4D) relative to every day (ED; (Eikelboom & Hewitt, 2016)⁠. Once these access-intake differences are established, they can be enduring, even if all rats are shifted to a common access schedule. Do changes in value accompany these access-induced solution intake changes? Three approaches were applied to test for access-induced value changes. First, following extended 24 h E3D (12 exposures) or ED (36 days) access to a flavoured 4% (Experiment 1) …

Characterization Of Micronutrient Dependent Growth By Several Temperate Freshwater Phytoplankton, Purnank Shah

Theses and Dissertations (Comprehensive)

Harmful algal blooms (HABs) are a growing problem in many freshwater waterbodies in Canada and around the world. HABs have wide-ranging impacts to ecosystems and economies. Since the 1970s, the primary focus of policies with respect to curbing HABs has been to lowering the inputs of P into waters. However, reports of HABs continue to increase even with all these P-removing policies in place. Some jurisdictions have chosen to focus on N-removal instead or in conjunction with P-removal to help with HABs. However, because some cyanobacteria have the ability to fix atmospheric N₂,N-removal might only lead to the …

To Like Or To Want? Exploring The Psychobiological Processes Of Human Food Reward, Angela Mastroianni

Theses and Dissertations (Comprehensive)

The Incentive Salience Theory (IST; Berridge and Robinson, 1998; 2016) has shown that wanting (craving) and liking (affective) processes can affect eating behaviour differently in animals. These processes often correlate but can dissociate (change differently) under certain circumstances as they rely on separate neural mechanisms (Berridge, 1996). More recently, work has been testing the IST in people by comparing broad food categories (Finlayson et al. 2007a; 2008). The results have been inconsistent, sparking debate about the theory's value for studying human feeding (Havermans, 2011; 2012).

This dissertation's aim was to explore if IST wanting and liking are independent processes controlling …
