Immune-Endocrine Links To Gregariousness In Wild House Mice, Patricia C. Lopes, Esther H. D. Carlitz, Morgan Kindel, Barbara König

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Social interactions are critically important for survival and impact overall-health, but also impose costs on animals, such as exposure to contagious agents. The immune system can play a critical role in modulating social behavior when animals are sick, as has been demonstrated within the context of “sickness behaviors.” Can immune molecules affect or be affected by social interactions even when animals are not sick, therefore serving a role in mediating pathogen exposure? We tested whether markers of immune function in both the blood and the brain are associated with gregariousness, quantified as number of animals interacted with per day. To …

Evaluation Of Severity And Factors Contributing To Foot Lesions In Endangered Ozark Hellbenders, Cryptobranchus Alleganiensis Bishopi, Rebecca H. Hardman, Kelly J. Irwin, William B. Sutton, Debra L. Miller

Agricultural and Environmental Sciences Faculty Research

Arkansas populations of Ozark Hellbenders, Cryptobranchus alleganiensis bishopi have declined precipitously over the past few decades and are now limited to a single river. Biologists have also observed an increase of distal limb lesions with unidentified etiology and unknown role in morbidity and mortality of the species in this location. We documented lesions and collected associated individual size class data and pathogen samples in Ozark Hellbenders of Arkansas (n = 73) from 2011 to 2014 with the following two objectives: (1) document spatiotemporal patterns and severity of lesions present in this last remaining Arkansas Ozark Hellbender population, and (2) determine …

Value Added Fed And Feeder Cattle Practices: Are They Paying?, Elliott James Dennis

Extension Farm and Ranch Management News

Summary

Some value added management programs clearly pay more than others and some do not pay at all. However, just like with a breeding or forage management strategy where not every year the cow gets bred back or the grass has sufficient protein, a value added program strategies premiums vary year to year. Switching the way cattle are managed and raised, handled, and fed requires planning and an understanding of labor and management capabilities. Not every cattle producer could or even should switch management practices an animal health protocol – even if premiums do exist. Thus, careful planning and consideration …

Bird Community Monitoring At Tallgrass Prairie National Preserve, Kansas, Status Report 2001–2018, David G. Peitz, Kathleen A. Kull

United States National Park Service: Publications

Executive Summary

In 2001, the Heartland I&M Network initiated breeding bird surveys on Tallgrass Prairie National Preserve, Kansas, to assess the ecological integrity of the preserve’s habitat. Birds are an important component of ecosystems and can serve as good indicators of habitat change in an ecosystem. In the 17 years of bird surveys at the preserve (2001 to 2018, excluding 2003), there were 2,089 plot visits and 119 different bird species recorded, 96 of which have the potential to breed within the preserve. These 96 species represent approximately 81% of the total species one would reasonably expect to have breeding …

Individual Variation In Winter Brook Trout (Salvelinus Fontinalis) Movement In A Small Northern Michigan Stream, Benjamin Bejcek

All NMU Master's Theses

Winter is a time of year of low temperatures and limited food availability. Brook trout (Salvelinus fontinalis) survival in winter is dependent on several factors including their condition after spawning in the fall and possibly their behavior in winter. Ice that forms during winter can potentially aid in survival by decreasing predation risk, decreasing stress, and acting as a thermal refuge. The emphasis of this project was to evaluate the relationship between movement patterns of brook trout and winter ice distribution. In the fall of 2017 and again in the fall of 2018, brook trout in a northern Michigan stream …

Migratory Flyways May Affect Population Structure In Double‐Crested Cormorants, Steven J.A. Kimble, Brian S. Dorr, Katie C. Hanson-Dorr, Olin E. Rhodes Jr., Travis L. Devault

United States Department of Agriculture Wildlife Services: Staff Publications

Double‐crested cormorants (Phalacrocorax auritus) recovered from a demographic bottleneck so well that they are now considered a nuisance species at breeding and wintering grounds across the United States and Canada. Management of this species could be improved by refining genetic population boundaries and assigning individuals to their natal population. Further, recent radio‐telemetry data suggest the existence of Interior and Atlantic migratory flyways, which could reduce gene flow and result in substantial genetic isolation. In this study, we used 1,784 individuals collected across the eastern United States, a large panel of microsatellite markers developed for this species, and individuals banded as …

The Effects Of Dietary Linoleic Acid And Hydrophilic Antioxidants On Basal, Peak, And Sustained Metabolism In Flight‐Trained European Starlings, Wales A. Carter, Kristen J. Demoranville, Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Dietary micronutrients have the ability to strongly influence animal physiology and ecology. For songbirds, dietary polyunsaturated fatty acids (PUFAs) and antioxidants are hypothesized to be particularly important micronutrients because of their influence on an individual's capacity for aerobic metabolism and recovery from extended bouts of exercise. However, the influence of specific fatty acids and hydrophilic antioxidants on whole‐animal performance remains largely untested. We used diet manipulations to directly test the effects of dietary PUFA, specifically linoleic acid (18:2n6), and anthocyanins, a hydrophilic antioxidant, on basal metabolic rate (BMR), peak metabolic rate (PMR), and rates of fat catabolism, lean catabolism, and …

Hassan, Zephania Irura, Clas Ahlm, Magnus Evander

All Peer-Reviewed Publications

Introduction Multiple outbreaks of Rift Valley Fever (RVF) with devastating effects have occurred in East Africa. These outbreaks cause disease in both livestock and humans and affect poor households most severely. Communities living in areas practicing nomadic livestock movement may be at higher risk of infection. This study sought to i) determine the human exposure to Rift Valley fever virus (RVFV) in populations living within nomadic animal movement routes in Kenya; and ii) identify risk factors for RVFV infection in these communities. Methods A cross-sectional descriptive study design was used. Samples were collected from the year 2014 to 2015 in …

Efficiency Of Using Electric Toothbrush As An Alternative To A Tuning Fork For Artificial Buzz Pollination Is Independent Of Instrument Buzzing Frequency, Mandeep Tayal, Jesus Chavana, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Background: Breeding programs and research activities where artificial buzz-pollinations are required to have primarily relied upon using tuning forks, and bumble bees. However, these methods can be expensive, unreliable, and inefficient. To find an alternative, we tested the efficiency of pollen collection using electric toothbrushes and compared it with tuning forks at three vibration frequencies—low, medium, and high and two extraction times at 3 s and 16 s- from two buzz—pollinated species (Solanum lycopersicum and Solanum elaeagnifolium).

Results: Our results show that species, and extraction time significantly influenced pollen extraction, while there were no significant differences for the different vibration …

Effects Of Deepwater Horizon Oil On Feather Structure And Thermoregulation In Gulls: Does Rehabilitation Work?, Katherine Horak, Nicole L. Barrett, Jeremy W. Ellis, Emma M. Campbell, Nicholas G. Dannemiller, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

Impacts of large-scale oil spills on avian species are far-reaching.While media attention often focuses on lethal impacts, sub-lethal effects and the impacts of rehabilitation receive less attention. The objective of our study was to characterize effects of moderate external oiling and subsequent rehabilitation on feather structure and thermoregulation in gulls. We captured 30 wild ring-billed gulls (Larus delawarensis) and randomly assigned each individual to an experimental group: 1) controls, 2) rehabilitated birds (externally oiled, rehabilitated by washing), or 3) oiled birds (externally oiled, not rehabilitated). We externally oiled birds with weathered MC252 Deepwater Horizon oil (water for controls) …

Transcriptome Analyses Of Liver In Newly-Hatched Chicks During The Metabolic Perturbation Of Fasting And Re-Feeding Reveals Thrspa As The Key Lipogenic Transcription Factor, Larry A. Cogburn, Nares Trakooljul, Xiaofei Wang, Laura E. Ellestad, Tom E. Porter

Biology Faculty Research

Background

The fasting-refeeding perturbation has been used extensively to reveal specific genes and metabolic pathways that control energy metabolism in the chicken. Most global transcriptional scans of the fasting-refeeding response in liver have focused on juvenile chickens that were 1, 2 or 4 weeks old. The present study was aimed at the immediate post-hatch period, in which newly-hatched chicks were subjected to fasting for 4, 24 or 48 h, then refed for 4, 24 or 48 h, and compared with a fully-fed control group at each age (D1-D4).

Results

Guinea Pig Transferrin Receptor 1 Mediates Cellular Entry Of Junín Virus And Other Pathogenic New World Arenaviruses, Brady T. Hickerson, Jonna B. Westover, Zhongde Wang, Young-Min Lee, Brian B. Gowen

Animal, Dairy, and Veterinary Science Faculty Publications

Several clade B New World arenaviruses (NWAs) can cause severe and often fatal hemorrhagic fever, for which preventive and therapeutic measures are severely limited. These NWAs use human transferrin receptor 1 (hTfR1) as a host cell receptor for virus entry. The most prevalent of the pathogenic NWAs is Junín virus (JUNV), the etiological agent of Argentine hemorrhagic fever. Small animal models of JUNV infection are limited because most laboratory rodent species are refractory to disease. Only guinea pigs are known to develop disease following JUNV infection, but the underlying mechanisms are not well characterized. In the present study, we demonstrate …

Oyster Mushroom (Pleurotus Ostreatus) Stipe Peptides As In-Vitro Radical Scavenging, Ferrous Iron Chelating, & Ferric Reducing Antioxidant Compounds, Suraj Meharwade

Food Science (MS) Theses

Ferrous iron chelating, ABTS radical scavenging, and ferric reducing antioxidant activity of mushroom stipe peptides obtained using Protamex® and V8 protease has not been investigated. Additionally, the effects of peptides on protein carbonyl formation during myofibrillar oxidation is unknown. Oxidation of lysine, arginine, and proline in myofibrillar protein from red meat results in reduced meat quality owing to changes in water composition. Therefore, the objective of this study was to compare the antioxidant performance of <1 kDa and 1-3 kDa mushroom peptides obtained by Protamex®-V8 hydrolysis against mushroom hydrolysate, mushroom protein, and mushroom stipe for radical scavenging, ferrous chelating, and ferric reducing activity, as well as their effects on protein carbonyl formation within a protein oxidation system. <1 kDa peptides exhibited significantly higher (p < 0.05) in-vitro ferrous iron chelating activity and ABTS radical scavenging activity as compared to mushroom stipe and 1-3 kDa peptides. Whereas, 1-3 kDa peptides demonstrated significantly …

Before And After The Storm: Interactions Between Tree-Fall Canopy Gaps, Plant Phenology, And Frugivorous Lemurs In Masoala National Park, Madagascar, Monica Sue Mogilewsky

Dissertations and Theses

Madagascar is one of Earth's top biodiversity hotspots, with 80% of life on the island considered endemic. Among the endemic species are lemurs, a diverse group of non-human primates. Unfortunately, Madagascar's diversity, including lemurs, is threatened by habitat degradation and loss. Despite intense anthropogenic pressure over the past 50 years, scientists have not detected any lemur extinctions during this period. Some researchers have proposed that lemurs' adaptations to natural disturbances have provided these taxa resiliency against anthropogenic disturbances. Certainly, Madagascar experiences an extreme disturbance regime: the island experiences an average of over three cyclones a year. These cyclones create numerous, …

Optimal Bait Density For Delivery Of Acute Toxicants To Vertebrate Pests, Kim M. Pepin, Nathan P. Snow, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Oral baiting is a fundamental method for delivering toxicants to pest species. Planning baiting strategies is challenging because bait-consumption rates depend on dynamic processes including space use and demographics of the target species. To determine cost-effective strategies for optimizing baiting, we developed a spatially explicit model of population dynamics using field-based measures of wild-pig (Sus scrofa) space use, bait consumption, and mortality probabilities. The most cost-effective baiting strategy depended strongly on the population reduction objective and initial density. A wide range of baiting strategies were cost-effective when the objective was 80% population reduction. In contrast, only a narrow range of …

Brodifacoum Residues In Fish Three Years After An Island-Wide Rat Eradication Attempt In The Tropical Pacific, Shane R. Siers, Aaron B. Shiels, Steven F. Volker, Kristen Rex, William C. Pitt

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive rats are known to threaten natural resources and human health and safety. Island-wide rat eradication attempts have been increasing in number and scale during the past several decades, as has the frequency of eradication success. The most common method to remove all rats from an island is to broadcast anticoagulant rodenticide bait into every rat’s home range on the island. Broadcast of toxicants can put humans and other nontarget species in marine and terrestrial environments at risk of exposure. The persistence of anticoagulant residues is somewhat unknown, particularly in marine environments. Three years after ~ 18,000 kg of 25 …

Seafood mislabeling has numerous consequences, including economic deception and food safety risks. The focus of this study was to investigate fish species labeling, use of acceptable market names, and Country of Origin Labeling (COOL) compliance for fresh fish fillets sold at grocery store seafood counters in Southern California. A total of 120 fillets representing 16 different categories of fish were collected from 30 Perishable Agricultural Commodities Act (PACA)-listed grocery stores. Each sample underwent DNA barcoding to identify the species. Acceptable market names were confirmed using the FDA Seafood List. Samples were determined to be compliant with COOL if both …

Sex Ratio Is Variable And Increasingly Male Biased At Two Colonies Of Magellanic Penguins, Natasha J. Gownaris, Pablo García Borboroglu, P. Dee Boersma

Environmental Studies Faculty Publications

Sex ratios are commonly skewed and variable in wild populations, but few studies track temporal trends in this demographic parameter. We examined variation in the operational sex ratio at two protected and declining breeding colonies of Magellanic Penguins (Spheniscus magellanicus) in Chubut, Argentina. Penguins from the two colonies, separated by 105 km, migrate north in the non‐breeding season and have overlapping distributions at sea. Conditions during the non‐breeding season can impact long‐term trends in operational sex ratio (i.e., through sex‐specific survival) and interannual variation in operational sex ratio (i.e., through sex‐specific breeding decisions). We found an increasingly male‐biased …

Predicting Changes In Bee Assemblages Following State Transitions At North American Dryland Ecotones, Melanie R. Kazenel, Karen W. Wright, Julieta Bettinelli, Terry L. Griswold, Kenneth D. Whitney, Jennifer A. Rudgers

All PIRU Publications

Drylands worldwide are experiencing ecosystem state transitions: the expansion of some ecosystem types at the expense of others. Bees in drylands are particularly abundant and diverse, with potential for large compositional differences and seasonal turnover across ecotones. To better understand how future ecosystem state transitions may influence bees, we compared bee assemblages and their seasonality among sites at the Sevilleta National Wildlife Refuge (NM, USA) that represent three dryland ecosystem types (and two ecotones) of the southwestern U.S. (Plains grassland, Chihuahuan Desert grassland, and Chihuahuan Desert shrubland). Using passive traps, we caught bees during two-week intervals from March–October, 2002–2014. The …
