Occupancy Analysis And Density Estimation Of Kori Bustards (Ardeotis Kori) And Helmeted Guineafowl (Numida Meleagris) For Use In Landscape Conservation Planning In The Northern Tuli Game Reserve, Botswana, Kathryn R. Mccollum

School of Natural Resources: Dissertations, Theses, and Student Research

For understudied species, more informed conservation planning and decision-making on both the local and landscape levels may be attained through the use of occupancy and abundance estimations. Here, we focus on two iconic bird species in eastern Botswana, kori bustards (Ardeotis kori) and helmeted guineafowl (Numida meleagris). The overall goal of this project was to better understand the hierarchy of factors that influence occupancy (ψ) and density of kori bustard and helmeted guineafowl populations within the Northern Tuli Game Reserve and how these factors may interact to affect landscape conservation and usage. We performed distance sampling …

Next-Generation Mrna Sequencing Reveals Pyroptosis-Induced Cd4+ T Cell Death In Early Simian Immunodeficiency Virus-Infected Lymphoid Tissues, Wuxun Lu, Andrew J. Demers, Fangrui Ma, Guobin Kang, Zhe Yuan, Yanmin Wan, Yue Li, Jiangqing Xu, Mark Lewis, Qingsheng Li

Nebraska Center for Biotechnology: Faculty and Staff Publications

Lymphoid tissues (LTs) are the principal sites where human immunodeficiency virus type 1 (HIV-1) replicates and virus-host interactions take place, resulting in immunopathology in the form of inflammation, immune activation, and CD4+ T cell death. The HIV-1 pathogenesis in LTs has been extensively studied; however, our understanding of the virus-host interactions in the very early stages of infection remains incomplete. We investigated virus-host interactions in the rectal draining lymph nodes (dLNs) of rhesus macaques at different times after intrarectal inoculation (days postinoculation [dpi]) with simian immunodeficiency virus (SIV). At 3 dpi, 103 differentially expressed genes (DEGs) were detected using next-generation …


Prescribed Fire Monitoring Report, Tallgrass Prairie National Preserve 2014 (Iqcs Fire Number 285382, 285383, 266782, 285677), Sherry A. Leis, Sarah E. Hinman Sep 2015

United States National Park Service: Publications

Introduction

In 2014, the preserve’s federal and NGO partners conducted prescribed fires during March, April, and October that encompassed 8129.8 acres of Tallgrass Prairie National Preserve (TAPR). This was a unique burn year in that prescribed burns occurred in the spring, the traditional burn season, and the fall. Fall burns were conducted to support needed archaeological surveys as part of the environmental compliance for a symphony event scheduled for June 2015 at the preserve. Burns at TAPR were coordinated with local US Fish and Wildlife Service (USFWS), The Nature Conservancy (TNC), and various units of the National Park Service.

Paleoepidemiology Of Intestinal Parasites And Lice In Pre-Columbian South America *, Adauto Araujo, Karl J. Reinhard, Daniela Leles, Luciana Sianto, Alena Iniguez, Martin Fugassa, Berrnardo Arriaza, Nancy Orellana, Luiz Fernando Ferreira

Karl Reinhard Publications

Some human parasites originated in prehominid ancestors in Africa. Nematode species, such as Enterobius vermicularis (pinworm), hookworms and Trichuris trichiura are shared by humans and other close phylogenetic primates (Pan and Gorilla), showing that they infected a common ancestor to this group. When humans migrated from Africa to other continents they carried these parasites wherever climate conditions allowed parasite transmission from host to host. Other parasites, however, were acquired throughout human biological and social evolutive history when new territories were occupied. Paleoparasitology data is a valuable source to recover emergence and disappearance of parasite infections through analysis of archaeological remains. …


Diet And Parasitism At Dust Devil Cave, Karl J. Reinhard, J Richard Ambler, Magdalene Mcguffie Aug 2015

Diet And Parasitism At Dust Devil Cave, Karl J. Reinhard, J Richard Ambler, Magdalene Mcguffie

Karl Reinhard Publications

Human parasitism has obvious relationships to group size and composition, mobility, subsistence patterns, and rates of culture change. At their best, human endoparasites may be annoying; at their worst, some can cause death. Thus, an overall view of the parasite load of a prehistoric population can yield insights useful in interpreting past lifeways. With these thoughts in mind, we undertook a study of Desha Complex (6800-4800 B .C.) human feces recovered from Dust Devil Cave in southern Utah.


Agave Chewing And Dental Wear: Evidence From Quids, Emily E. Hammerl, Melissa A. Baier, Karl Reinhard Jul 2015

Agave Chewing And Dental Wear: Evidence From Quids, Emily E. Hammerl, Melissa A. Baier, Karl Reinhard

Karl Reinhard Publications

Agave quid chewing is examined as a potential contributing behavior to hunter-gatherer dental wear. It has previously been hypothesized that the contribution of Agave quid chewing to dental wear would be observed in communities wherever phytolith-rich desert succulents were part of subsistence. Previous analysis of coprolites from a prehistoric agricultural site, La Cueva de los Muertos Chiquitos in Durango, Mexico, showed that Agave was a consistent part of a diverse diet. Therefore, quids recovered at this site ought to be useful materials to test the hypothesis that dental wear was related to desert succulent consumption. The quids recovered from the …

Predictors Of Preschool Children's Body Mass Index: Breastfeeding Duration, Child Eating Behaviors, And Parental Feeding Practices, Amy J. Encinger

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The current study examined how breastfeeding duration, child eating behaviors (Satiety and Food Responsiveness), and parental feeding practices (Environment and Parental Control over Food) are related to body mass index (BMI) among preschool-aged children. Participants were 224 primary caregivers (M age = 30.36; 90% mothers) of preschool-aged children (M age = 4.22 years, 55% male) from three Midwestern preschools serving low-income children. Mediated multiple regression analyses examined the effects of the various child eating behaviors and parental feeding practices as mediators of the relation between breastfeeding duration and child BMI. Three main findings emerged. There was a significant …


Container Vegetable Gardening, Terri James, David Lott Jul 2015

Container Vegetable Gardening, Terri James, David Lott

Nebraska Extension: Faculty and Staff Publications

If well-managed, vegetables grown in containers can provide high-quality produce in a small space.

Container vegetable gardening is a wonderful option for people who have limited space, impaired physical mobility, or conditions that interfere with in-ground gardening, such as poor garden soil. It also can help avoid problems with soilborne diseases and nematode pests that can exist in the soil in traditional, in-ground gardens. People who do not have access to a garden space, or simply do not want to grow a full-scale garden, may choose container vegetable gardening to provide them with enjoyment and produce. Containers are available in …


Embracing Multiple Definitions Of Learning, Andrew B. Barron, Eileen A. Hebets, Thomas A. Cleland, Courtney L. Fitzpatrick, Mark E. Hauber, Jeffrey R. Stevens Jul 2015

Embracing Multiple Definitions Of Learning, Andrew B. Barron, Eileen A. Hebets, Thomas A. Cleland, Courtney L. Fitzpatrick, Mark E. Hauber, Jeffrey R. Stevens

Eileen Hebets Publications

Definitions of learning vary widely across disciplines, driven largely by different approaches used to assess its occurrence. These definitions can be better reconciled with each other if each is recognized as coherent with a common conceptualization of learning, while appreciating the practical utility of different learning definitions in different contexts.

Learning is a major focus of research in psychology, neuro- science, behavioral ecology, evolutionary theory, and computer science, as well as in many other disciplines. Despite its conceptual prevalence, definitions of learning differ enormously both within and between these disciplines, and new definitions continue to be proposed [1]. Ongoing disputes …


How Access To Plant & Animal Books Affects Participation In Conservation Activities, Dustin Ingram, Hassnaa Ingram May 2015

How Access To Plant & Animal Books Affects Participation In Conservation Activities, Dustin Ingram, Hassnaa Ingram

Library Philosophy and Practice (e-journal)

Abstract

Public libraries are an important resource for communities. Access to plant and animal books impacts a communities’ ability to learn about their environment. In this study, the number of plant and animal books available to people through local libraries in northern Kentucky, and neighboring counties in Ohio and Indiana were counted and a survey assessing one’s preferences and likeliness to participate in conservation activities was distributed to local residents. Based on the collected data, a statistically significant relationship (p < 0.05) was found between access to plant and animal books available at local libraries and the likelihood of people to participate in conservation activities. Further analysis was performed between the total number of shelved plant and animal books at local libraries, the total number of shelved juvenile plant and animal books and the shelved adult plant and animal books, and the total number of plant and animal books in libraries compared to the local household income and number of households near a library. This study found that people that read books about plants and animals were more likely to participate in conservation activities associated with their book preference. This study also found that people living in low-income communities with fewer households are less likely to participate in plant and animal conservation, as compared to higher-income communities with a higher number of households. Additionally, this study found that lower income areas have fewer plant and animal books on the library shelves than higher income areas. Consequently, study results suggest that if more plant and animal books were made available to low-income areas and areas of biological importance through libraries, people may be more likely to conserve the wildlife around them.


Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie May 2015

Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie

School of Natural Resources: Dissertations, Theses, and Student Research

Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered the wetland landscape in both …


An Exploratory High-Density Eeg Investigation Of The Misinformation Effect: Attentional And Recollective Differences Between True And False Perceptual Memories, John E. Kiat, Robert F. Belli May 2015

An Exploratory High-Density Eeg Investigation Of The Misinformation Effect: Attentional And Recollective Differences Between True And False Perceptual Memories, John E. Kiat, Robert F. Belli

Department of Psychology: Faculty Publications

The misinformation effect, a phenomenon in which eyewitness memories are altered via exposure to post-event misinformation, is one of the most important paradigms used to investigate the reconstructive nature of human memory. The aim of this study was to use the misinformation effect paradigm to investigate differences in attentional and recollective processing between true and false event memories. Nineteen participants completed a variant of the misinformation paradigm in which recognition responses to true and misinformation based event details embedded within a narrative context, were investigated using high-density (256-channel) EEG with a 1-day delay between event exposure and test. Source monitoring …

Piecemeal Reform Of Trade And Environmental Policy When Consumption Also Pollutes, Mark R. Metcalfe, John C. Beghin Jan 2015

Piecemeal Reform Of Trade And Environmental Policy When Consumption Also Pollutes, Mark R. Metcalfe, John C. Beghin

Department of Agricultural Economics: Faculty Publications

We incorporate endogenous (price-responsive) consumption pollution into a dual trade model to assess welfare effects of coordinated trade and environmental piecemeal reform in a small, open and distorted economy. Pollution is generated by production and consumption. Producers control the level of pollution and face incentives to abate both types of pollution. We identify sufficient conditions for welfare-improving reforms of trade and environmental policies. An additional domestic environmental policy instrument must be imposed on exportables because of their supply response to foreign environmental taxes.


Yellowstone Wolf (Canis Lupus) Density Predicted By Elk (Cervus Elaphus) Biomass, L. David Mech, Shannon M. Barber-Meyer Jan 2015

Yellowstone Wolf (Canis Lupus) Density Predicted By Elk (Cervus Elaphus) Biomass, L. David Mech, Shannon M. Barber-Meyer

USGS Northern Prairie Wildlife Research Center

The Northern Range (NR) of Yellowstone National Park (YNP) hosts a higher prey biomass density in the form of elk (Cervus elaphus L., 1758) than any other system of gray wolves (Canis lupus L., 1758) and prey reported. Therefore, it is important to determine whether that wolf–prey system fits a long-standing model relating wolf density to prey biomass. Using data from 2005 to 2012 after elk population fluctuations dampened 10 years subsequent to wolf reintroduction, we found that NR prey biomass predicted wolf density. This finding and the trajectory of the regression extend the validity of the model …


Evaluation Of A Formula That Categorizes Female Gray Wolf Breeding Status By Nipple Size, Shannon M. Barber-Meyer, L. David Mech Jan 2015

Evaluation Of A Formula That Categorizes Female Gray Wolf Breeding Status By Nipple Size, Shannon M. Barber-Meyer, L. David Mech

USGS Northern Prairie Wildlife Research Center

The proportion by age class of wild Canis lupus (Gray Wolf) females that reproduce in any given year remains unclear; thus, we evaluated the applicability to our long-term (1972–2013) data set of the Mech et al. (1993) formula that categorizes female Gray Wolf breeding status by nipple size and time of year. We used the formula to classify Gray Wolves from 68 capture events into 4 categories (yearling, adult non-breeder, former breeder, current breeder). To address issues with small sample size and variance, we created an ambiguity index to allow some Gray Wolves to be classed into 2 categories. We …

Repeated Effects Of The Neurotensin Receptor Agonist Pd149163 In Three Animal Tests Of Antipsychotic Activity: Assessing For Tolerance And Cross-Tolerance To Clozapine, Shinnyi Chou, Collin Davis, Sean Jones, Ming Li Jan 2015

Repeated Effects Of The Neurotensin Receptor Agonist Pd149163 In Three Animal Tests Of Antipsychotic Activity: Assessing For Tolerance And Cross-Tolerance To Clozapine, Shinnyi Chou, Collin Davis, Sean Jones, Ming Li

Department of Psychology: Faculty Publications

Neurotensin is an endogenous neuropeptide closely associated with the mesolimbic dopaminergic system and shown to possess antipsychotic-like effects. In particular, acute neurotensin receptor activation can inhibit conditioned avoidance response (CAR), attenuate phencyclidine (PCP)-induced prepulse inhibition (PPI) disruptions, and reverse PCP-induced hyperlocomotion. However, few studies have examined the long term effects of repeated neurotensin receptor activation and results are inconsistent. Since clinical administration of antipsychotic therapy often requires a prolonged treatment schedule, here we assessed the effects of repeated activation of neurotensin receptors using an NTS1 receptor selective agonist, PD149163, in 3 behavioral tests of antipsychotic activity. We also investigated whether …


Gray Wolf (Canis Lupus) Dyad Monthly Association Rates By Demographic Group, Shannon M. Barber-Meyer, L. David Mech Jan 2015

Gray Wolf (Canis Lupus) Dyad Monthly Association Rates By Demographic Group, Shannon M. Barber-Meyer, L. David Mech

USGS Northern Prairie Wildlife Research Center

Preliminary data from GPS-collared wolves (Canis lupus) in the Superior National Forest of northeastern Minnesota indicated wolves had low association rates with packmates during summer. However, aerial-telemetry locations of very high frequency (VHF)-radioed wolves in this same area showed high associations among packmates during winter. We analyzed aerial-telemetry-location data from VHF-collared wolves in several packs (n=18 dyads) in this same area from 1994-2012 by month, and found lowest association rates occurred during June. While other studies have found low association among wolf packmates during summer, information on differences in association patterns depending on the wolf associates’ demographics is …


White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer Jan 2015

White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer

USGS Northern Prairie Wildlife Research Center

Little is known about how often various prey animals are at risk of predation by Gray Wolves (Canis lupus). We used a system to monitor the presence during the day of two radio-collared Gray Wolves within 2 km of a radio-collared White-tailed Deer (Odocoileus virginianus) with a fawn or fawns in August 2013 in the Superior National Forest of northeastern Minnesota. We concluded that the fawn or fawns were at risk of predation by at least one wolf at least daily.
