Population Ecology Of The Queensnake (Regina Septemvittata) In An Urban Creek, 2008 To 2019, Rachel Beiler, R. Elliot Miller, Norman Reichenbach Dec 2021

Population Ecology Of The Queensnake (Regina Septemvittata) In An Urban Creek, 2008 To 2019, Rachel Beiler, R. Elliot Miller, Norman Reichenbach

Faculty Publications and Presentations

Habitat fragmentation is a common result of urbanization and species living in these fragments are at risk of extirpation. We conducted a 12-y (2008–2019) capture-mark-recapture study on snakes living in a 593-m section of Rock Castle Creek flowing through an urban area in central Virginia, USA. Our study site was occupied primarily by Queensnakes (Regina septemvittata). We used data from 168 individual Queensnakes to examine several aspects of their population ecology including survival rates (0.52), reproductive effort (21.3% juvenile to adult ratio), growth rates (68% and 30.6% increase for 1 to 2 y-old and 2 to 3+ y-old snakes, respectively), …

Recent studies observed a correlation between estrogen-related cancers and groundwater atrazine in eastern Nebraska counties. However, the mechanisms of human exposure to atrazine are unclear because low groundwater atrazine concentration was observed in counties with high cancer incidence despite having the highest atrazine usage. We studied groundwater atrazine fate in high atrazine usage Nebraska counties. Data were collected from Quality Assessed Agrichemical Contaminant Nebraska Groundwater, Parameter–Elevation Regressions on Independent Slopes Model (PRISM), and water use databases. Descriptive statistics and cluster analysis were performed. Domestic wells (59%) were the predominant well type. Groundwater atrazine was affected by well depth. Clusters consisting …

Stink Bug (Hemiptera: Heteroptera: Pentatomidae) Ecology In Nebraska Agroecosystems, Blessing Ademokoya Dec 2021

Stink Bug (Hemiptera: Heteroptera: Pentatomidae) Ecology In Nebraska Agroecosystems, Blessing Ademokoya

Department of Entomology: Dissertations, Theses, and Student Research

Stink bugs (Hemiptera: Heteroptera: Pentatomidae) have gained considerable attention in Nebraska in the last decade due to increasing densities of native stink bug and spread of invasive species in the Midwest. Little is known about stink bug dynamics in Nebraska cropping systems. Based on data from a recent field survey, specimens at the University of Nebraska State Museum and the diagnostic lab of the Entomology Department at the University of Nebraska Lincoln, as well as published literature, we present a checklist of 72 species and subspecies of Pentatomidae (55 Pentatominae, 13 Asopinae, 3 Podopinae and 1 Edessinae) that occur in …

There has been a steady rise in the use of dormant propagules to study biotic responses to environmental change over time. This is particularly important for organisms that strongly mediate ecosystem processes, as changes in their traits over time can provide a unique snapshot into the structure and function of ecosystems from decades to millennia in the past. Understanding sources of bias and variation is a challenge in the field of resurrection ecology, including those that arise because often-used measurements like seed germination success are imperfect indicators of propagule viability. Using a Bayesian statistical framework, we evaluated sources of variability …

Data from 790 older school-age (Mage = 10.2 years, SD = 1.2 years) girls (N = 427) and boys from Barranquilla, Colombia (N = 449) and Montréal, Canada (N = 331) were used to replicate findings reported by Valdivia et al. (2005). This prior study revealed contextual variations in the association between two measures of social behavior, specifically aggression and withdrawal, and two measures of effective functioning with peers, specifically sociometric preference and friendship. The Montréal participants were primarily from families with European backgrounds. The ethnicity of the participants from Barranquilla can be described as Latinx/Caribbean. Multilevel analyses provided evidence …

Biology Faculty Publications

Between 2000-2020, more than ten new populations of the invasive American bullfrog (Lithobates catesbeianus) have been reported in the southern cone of South America. We studied the stomach contents of 126 bullfrogs from a population at an early invasion stage in Uruguay (Acegua, Cerro Largo Department). We observed a rich diet, with extensive prey volume range (1 mm3 to more than 7 000 mm(3)); the most frequent items were Hymenoptera (19.6%), Coleoptera (16.4%), Amphipoda (13.3%), Anura (8.9%) and Heteroptera (8.7%). Despite some overlap, differences were observed in volume (chi(2) = 54.6, p <0.001, d.f. = 2) and prey quantity (F = 8.1, p <0.001, d.f. = 79) between males, females, and juveniles. Juveniles showed significantly higher consumption of terrestrial prey by count (82% of their total ingestion) than adults (29% for males and 32% for females) (chi(2) = 28.5, p <0.001, d.f. = 2). Adults, especially females, showed a high frequency of cannibalism (33% of their total ingestion; chi(2) = 20.9, p <0.001, d.f. = 2). Comparing our data with other bullfrog regional studies, we found great plasticity in trophic habits and differences in the incidence of cannibalism (higher incidence in the populations of Acegua, Uruguay, and Buenos Aires, Argentina). These differences could be related to local biodiversity, but also could be affected by the invasion phase. Cannibalism frequency was higher in small bullfrog populations, where it could be favoring the establishment success. This shift in foraging strategies during the invasion process had been insufficiently evaluated in amphibians. Knowing the ecological determinants for the invasion by bullfrogs can be useful to the development of management strategies.

Department of Biochemistry: Faculty Publications

Advances in quantitative biology data collection and analysis across scales (molecular, cellular, organismal, and ecological) have transformed how we understand, categorize, and predict complex biological systems. This surge of quantitative data creates an opportunity to apply, develop, and evaluate mathematical models of biological systems and explore novel methods of analysis. Simultaneously, thanks to increased computational power, mathematicians, engineers, and physical scientists have developed sophisticated models of biological systems at different scales. Novel modeling schemes can offer deeper understanding of principles in biology, but there is still a disconnect between modeling and experimental biology that limits our ability to fully realize …


Knowledge Awareness Of Camouflage Skills In Females With High-Functioning Autism Among Health Care Providers In Miami-Dade County, Florida: A Quality Improvement Project, Tahnee Diaz Rodriguez Dec 2021

Knowledge Awareness Of Camouflage Skills In Females With High-Functioning Autism Among Health Care Providers In Miami-Dade County, Florida: A Quality Improvement Project, Tahnee Diaz Rodriguez

Nicole Wertheim College of Nursing Student Projects

Healthcare providers are more likely to recognize autism in males than females in the United States (U.S.). Females with high-functioning autism are under screened, misdiagnosed, or receive an autism diagnosis at a later age at higher rates than their male counterparts in the U.S. Research indicates that camouflage skills in females with high-functioning autism, as well as knowledge deficits among healthcare providers contribute to the clinical problem. The purpose of this quality improvement project was to increase knowledge awareness of camouflage skills in females with high-functioning autism among healthcare providers in Miami-Dade County, Florida. This project aimed to contribute to …


Deterring Non-Target Birds From Toxic Bait Sites For Wild Pigs, Nathan P. Snow, Joseph M. Halseth, Justin A. Foster, Michael J. Lavelle, Justin W. Fischer, Michael P. Glow, Ingrid A. Messer, Seth M. Cook, Kurt C. Vercauteren Dec 2021

United States Department of Agriculture Wildlife Services: Staff Publications

Toxic baiting of wild pigs (Sus scrofa) is a potential new tool for population control and damage reduction in the US. Field trials testing a prototype toxic bait (HOGGONE 2 containing 5% sodium nitrite [SN]), though, revealed that wild pigs spilled small particles of toxic bait outside of bait stations which subsequently created hazards for non-target species that consumed those particles, primarily passerine birds. To deter non-target birds from consuming particles of spilled bait, we tested four deterrents at mock bait sites (i.e., baited with bird seed) in north-central Colorado, USA during April–May 2020. We found a programable, inflatable deterrent …

Drivers Of Understory Plant Communities In Sierra Nevada Mixed Conifer Forests With Pyrodiversity, Kate Wilkin, Lauren Ponisio, Danny L. Fry, Brandon M. Collins, Tadashi Moody, Scott L. Stephens

Faculty Research, Scholarly, and Creative Activity

Background: Fire suppression in western North America increased and homogenized overstory cover in conifer forests, which likely affected understory plant communities. We sought to characterize understory plant communities and their drivers using plot-based observations from two contemporary reference sites in the Sierra Nevada, USA. These sites had long-established natural fire programs, which have resulted in restored natural fire regimes. In this study, we investigated how pyrodiversity—the diversity of fire size, severity, season, and frequency—and other environment factors influenced species composition and cover of forest understory plant communities. Results: Understory plant communities were influenced by a combination of environmental, plot-scale recent …

Background: Transcriptomic data has demonstrated utility to advance the study of physiological diversity and organisms’ responses to environmental stressors. However, a lack of genomic resources and challenges associated with collecting high-quality RNA can limit its application for many wild populations. Minimally invasive blood sampling combined with de novo transcriptomic approaches has great potential to alleviate these barriers. Here, we advance these goals for marine turtles by generating high quality de novo blood transcriptome assemblies to characterize functional diversity and compare global transcriptional profiles between tissues, species, and foraging aggregations. Results: We generated high quality blood transcriptome assemblies for hawksbill (Eretmochelys …

Global Distribution And Richness Of Armillaria And Related Species Inferred From Public Databases And Amplicon Sequencing Datasets, Rachel A. Koch, Joshua Herr Nov 2021

Global Distribution And Richness Of Armillaria And Related Species Inferred From Public Databases And Amplicon Sequencing Datasets, Rachel A. Koch, Joshua Herr

Department of Plant Pathology: Faculty Publications

Armillaria is a globally distributed fungal genus most notably composed of economically important plant pathogens that are found predominantly in forest and agronomic systems. The genus sensulato has more recently received attention for its role in woody plant decomposition and in mycorrhizal symbiosis with specific plants. Previous phylogenetic analyses suggest that around 50 species are recognized globally. Despite this previous work, no studies have analyzed the global species richness and distribution of the genus using data derived from fungal community sequencing datasets or barcoding initiatives. To assess the global diversity and species richness of Armillaria, we mined publicly available sequencing …

Abortion is a common but controversial phenomenon globally. The discourse on the legality of abortion remains intricate, leaving a substantial number of women restricted from accessing safe abortion. There are evidence of an association between restrictive abortion laws, unsafe abortions, and maternal mortality in low-and middle-income countries (LMICs). We explore how restrictive abortion laws violate women’s right to health and bodily integrity. We used Carol Bacchi’s policy framework to analyze how restrictive abortion laws have been discursively framed (problematization); the assumptions that underpinned the representation; the consequences of the representation; what was left unproblematic; how the representation could be questioned, …

All Faculty

West African crocodylians are among the most threatened and least studied crocodylian species globally. Assessing population status and establishing a basis for population monitoring is the highest priority action for this region. Monitoring of crocodiles is influenced by many factors that affect detectability, including environmental variables and individual- or population-level wariness. We investigated how these factors affect detectability and counts of the critically endangered Mecistops cataphractus and the newly recognized Crocodylus suchus. We implemented 195 repetitive surveys at 38 sites across Côte d’Ivoire between 2014 and 2019. We used an occupancy-based approach and a count-based GLMM analysis to determine the …

The Influence Of Maternal Glucocorticoids On Offspring Phenotype In High-And Low-Risk Environments, Kirsty J. Macleod, Tracy Langkilde, Cameron P. Venable, David C. Ensminger, Michael J. Sheriff Nov 2021

The Influence Of Maternal Glucocorticoids On Offspring Phenotype In High-And Low-Risk Environments, Kirsty J. Macleod, Tracy Langkilde, Cameron P. Venable, David C. Ensminger, Michael J. Sheriff

Faculty Research, Scholarly, and Creative Activity

Elevated maternal glucocorticoid levels during gestation can lead to phenotypic changes in offspring via maternal effects. Although such effects have traditionally been considered maladaptive, maternally derived glucocorticoids may adaptively prepare offspring for their future environment depending upon the correlation between maternal and offspring environments. Nevertheless, relatively few studies test the effects of prenatal glucocorticoid exposure across multiple environments. We tested the potential for ecologically relevant increases in maternal glucocorticoids in the eastern fence lizard (Sceloporus undulatus) to induce adaptive phenotypic changes in offspring exposed to high or low densities of an invasive fire ant predator. Maternal treatment had limited effects …

Active transportation (AT) is widely viewed as an important target for increasing participation in aerobic physical activity and improving health, while simultaneously addressing pollution and climate change through reductions in motor vehicular emissions. In recent years, progress in increasing AT has stalled in some countries and, furthermore, the coronavirus (COVID-19) pandemic has created new AT opportunities while also exposing the barriers and health inequities related to AT for some populations. This paper describes the results of the December 2019 Conference on Health and Active Transportation (CHAT) which brought together leaders from the transportation and health disciplines. Attendees charted a course …

Hyperspectral Reflectance-Based Phenotyping For Quantitative Genetics In Crops: Progress And Challenges, Marcin Grzybowski, Kuwan K. Wijewardane, Abbas Atefi, Yufeng Ge, James C. Schnable

Center for Plant Science Innovation: Faculty and Staff Publications

Many biochemical and physiological properties of plants that are of interest to breeders and geneticists have extremely low throughput and/or can only be measured destructively. This has limited the use of information on natural variation in nutrient and metabolite abundance, as well as photosynthetic capacity in quantitative genetic contexts where it is necessary to collect data from hundreds or thousands of plants. A number of recent studies have demonstrated the potential to estimate many of these traits from hyperspectral reflectance data, primarily in ecophysiological contexts. Here, we summarize recent advances in the use of hyperspectral reflectance data for plant phenotyping, …

Long-distance migrants are under strong selection to arrive on their breeding grounds at a time that maximizes fitness. Many arctic birds start nesting shortly after snow recedes from their breeding sites and timing of snowmelt can vary substantially over the breeding range of widespread species. We tested the hypothesis that migration schedules of individuals co-occurring at the same non-breeding areas are adapted to average local environmental conditions encountered at their specific and distant Arctic breeding locations. We predicted that timing of breeding site availability (measured here as the average snow-free date) should explain individual variation in departure time from shared …

Agrichemicals, chemicals used to maximize crop and animal production, can lead to water quality concerns when these chemicals run off into surface and groundwater after precipitation events. In Nebraska, one such chemical is atrazine, a suspected carcinogen. This study evaluated the association between atrazine in surface and groundwater, in relation to the incidence of pediatric cancer in Nebraska watersheds over 30 years (1 January 1987 to 31 December 2016). The watersheds were grouped into four categories based on the average atrazine concentration over the study period, using quantile classification. The associations between atrazine (ground/surface) and pediatric cancer after adjusting for …


Diversifying Bioenergy Crops Increases Yield And Yield Stability By Reducing Weed Abundance, Jacob M. Jungers, Yi Yang, Christopher W. Fernandez, Forest Isbell, Clarence Lehman, Don Wyse, Craig Sheaffer Oct 2021

Diversifying Bioenergy Crops Increases Yield And Yield Stability By Reducing Weed Abundance, Jacob M. Jungers, Yi Yang, Christopher W. Fernandez, Forest Isbell, Clarence Lehman, Don Wyse, Craig Sheaffer

Dartmouth Scholarship

Relationships between species diversity, productivity, temporal stability of productivity, and plant invasion have been well documented in grasslands, and these relationships could translate to improved agricultural sustainability. However, few studies have explored these relationships in agricultural contexts where fertility and weeds are managed. Using 7 years of biomass yield and species composition data from 12 species mixture treatments varying in native species diversity, we found that species richness increased yield and interannual yield stability by reducing weed abundance. Stability was driven by yield as opposed to temporal variability of yield. Nitrogen fertilization increased yield but at the expense of yield …


On The State Of Dance Philosophy, Curtis L. Carter Oct 2021

On The State Of Dance Philosophy, Curtis L. Carter

Philosophy Faculty Research and Publications

What are Eric Mullis’s contributions to a pragmatist philosophy of dance? First, the work brings attention to aspects of dance in regional and religious contexts and to a selection of religious dance practices (Pentecostal and Quaker) not typically addressed in the literature of dance philosophy, thus adding to the current scope of dance studies. This book’s main strength with respect to pragmatist philosophies is its efforts to apply existing theories of pragmatism (James and Dewey, with commentary on Shusterman’s neopragmatist somaesthetics) to aspects of dance in a particular regional setting. This task is accomplished with three aspects of the research: …
