Tree Resprout Dynamics Following Fire Depend On Herbivory By Wild Ungulate Herbivores, Eric M. Lamalfa, Duncan M. Kimuyu, Ryan L. Sensenig, Truman P. Young, Corinna Riginos, Kari E. Veblen

Wildland Resources Faculty Publications

1. Savanna tree cover is dynamic due to disturbances such as fire and herbivory. Frequent fires can limit a key demographic transition from sapling to adult height classes in savanna trees. Saplings may be caught in a ‘fire trap’, wherein individuals repeatedly resprout following fire top-kill events. Saplings only rarely escape the cycle by attaining a fire-resistant height (e.g. taller than the minimum scorch height) during fire-free intervals.
2. Large mammalian herbivores also may trap trees in shorter size classes. Browsing herbivores directly limit sapling height, while grazing herbivores such as cattle facilitate sapling growth indirectly via grass removal. Experimental studies investigating …

Efficacy Of A Ml336 Derivative Against Venezuelan And Eastern Equine Encephalitis Viruses, Colleen B. Jonsson, Xufeng Cao, Jasper Lee, Jon D. Gabbard, Yong-Kyu Chu, Elizabeth A. Fitzpatrick, Justin G. Julander, Dong-Hoon Chung, Jennifer Stabenow, Jennifer E. Golden

Animal, Dairy, and Veterinary Science Faculty Publications

Currently, there are no licensed human vaccines or antivirals for treatment of or prevention from infection with encephalitic alphaviruses. Because epidemics are sporadic and unpredictable, and endemic disease is common but rarely diagnosed, it is difficult to identify all populations requiring vaccination; thus, an effective post-exposure treatment method is needed to interrupt ongoing outbreaks. To address this public health need, we have continued development of ML336 to deliver a molecule with prophylactic and therapeutic potential that could be relevant for use in natural epidemics or deliberate release scenario for Venezuelan equine encephalitis virus (VEEV). We report findings from in vitro …

Harnessing Writing In The Wild: Practical Applications Of Affinity Spaces For English Language Instruction, Marta Dominika Halaczkiewicz

Languages, Philosophy, and Communication Studies Faculty Publications

In this article the author explores ways in which affinity spaces (Gee, 2004) can be adapted for English language instruction. Affinity spaces attract participants who enthusiastically share their passions, such as popular culture, video games, or literature. Researchers have found that affinity spaces contribute to improvements in reading (Steinkuehler, Compton‐Lilly, & King, 2010) and writing (Black, 2007) literacy of both native English speakers and English language learners. Previous research has explored applications of these spaces in language instruction, including incorporating topics from popular culture in courses and engaging students in online writing (Sauro & Sundmark, 2016). Other adaptations have used …

Wild Bee Diversity Increases With Local Fire Severity In A Fire‐Prone Landscape, Sara M. Galbraith, James H. Cane, Andrew R. Moldenke, James W. Rivers

All PIRU Publications

As wildfire activity increases in many regions of the world, it is imperative that we understand how key components of fire‐prone ecosystems respond to spatial variation in fire characteristics. Pollinators provide a foundation for ecological communities by assisting in the reproduction of native plants, yet our understanding of how pollinators such as wild bees respond to variation in fire severity is limited, particularly for forest ecosystems. Here, we took advantage of a natural experiment created by a large‐scale, mixed‐severity wildfire to provide the first assessment of how wild bee communities are shaped by fire severity in mixed‐conifer forest. We sampled …

Navigating Award-Winning Nonfiction Children's Literature, Jennifer M. Smith, Marla K. Robertson

Teacher Education and Leadership Faculty Publications

Nonfiction children's literature has changed in recent years, including an increase in organizational, design, and text features. The authors conducted a content analysis of 112 nonfiction award-winning and honor books from 2000 to 2018 to examine how the books have changed over time. The authors discuss the patterns, changes, and complexities found in nonfiction children's literature and provide text sets and guiding questions for classroom instruction and exploration of three features that appear in books in a variety of ways and may be challenging for students: atypical text, graphics with information, and supplemental expository information.

Low-Cost, Open-Source, And Low-Power: But What To Do With The Data?, Jeffery S. Horsburgh, Juan Caraballo, Maurier Ramírez, Anthony K. Aufdenkampe, David B. Arscott, Sara Geleskie Damiano

Civil and Environmental Engineering Faculty Publications

There are now many ongoing efforts to develop low-cost, open-source, low-power sensors and datalogging solutions for environmental monitoring applications. Many of these have advanced to the point that high quality scientific measurements can be made using relatively inexpensive and increasingly off-the-shelf components. With the development of these innovative systems, however, comes the ability to generate large volumes of high-frequency monitoring data and the challenge of how to log, transmit, store, and share the resulting data. This paper describes a new web application that was designed to enable citizen scientists to stream sensor data from a network of Arduino-based dataloggers to …

The Role Of Disease & Insects In Aspen Ecology, John C. Guyon Ii

Aspen Bibliography

Aspen is a keystone species in montane forests, and enhances a number of key resource values including wildlife habitat, water resources, and fire behavior. Recently, aspen forests have experienced episodes of dieback and decline across western North America (Worrall et al. 2010, Guyon and Hoffman 2011). A large proportion of the dieback and decline has been linked to drought stress or drought-prone locations (Hanna and Kulakowski 2012). However, insects and diseases are commonly found in declining aspen stands, leading to confusion about the role of insects and diseases in aspen ecology. Additionally, aspen has a reputation for being susceptible to …

Mapping Of Dynamic Transcriptome Changes Associated With Silica-Triggered Autoimmune Pathogenesis In The Lupus-Prone Nzbwf1 Mouse, Melissa A. Bates, Abby D. Benninghoff, Kristen N. Gilley, Andrij Holian, Jack R. Harkema, James J. Pestka

Animal, Dairy, and Veterinary Science Faculty Publications

Crystalline silica (cSiO₂) is a widely recognized environmental trigger of autoimmune disease. In the lupus-prone female NZBWF1 mouse, airway exposure to cSiO₂ triggers pulmonary ectopic lymphoid neogenesis, systemic autoantibody elevation, and glomerulonephritis. Here we tested the hypothesis that upregulation of adaptive immune function genes in the lung precedes cSiO₂-triggering of autoimmune disease in this model. The study include three groups of mice, as follows: (1) necropsied 1 d after a single intranasal instillation of 1 mg cSiO₂ or vehicle, (2) necropsied 1 d after four weekly single instillations of 1 mg cSiO₂ or …

Peloton Tracking And Analysis From The 2016 Tour De France, Tadd T. Truscott, Jesse Belden

Browse all Datasets

The work associated with this project is described in a manuscript entitled "How vision governs the collective behavior of cycling pelotons" by Belden et al., along with an electronic supplementary material document. We investigate properties of densely packed groups of bicycle racers, which are known as cycling pelotons. These pelotons exhibit features of collective animal behavior, including emergent behavior from inter-individual interactions. In this data set, we classify global shapes of the peloton, and identify and track individual cyclists to determine the details of network structure. We also investigate motion waves that propagate through the pelotons.

Double-Crested Cormorant Colony Effects On Soil Chemistry, Vegetation Structure And Avian Diversity In A Southeastern Reservoir System, Leah Moran Veum, Brian Dorr, Katie Hanson-Dor, R. J. Moore, Scott A. Rush

Wildlife Damage Management Conference

Ornithogenic material delivered by Double-crested Cormorants (Phalacrocorax auritus) from their nesting colonies have been documented to effect vegetation, soil chemistry and tree and plant health in the northern breeding grounds of Canada and the United States (U.S.). However, little work has been done on impacts to avian communities or in temperate forest ecosystems. We compared soil chemistry, vegetation and tree structure and diversity and effects on avian communities among colony islands, uninhabited islands and abandoned colony islands within Guntersville Reservoir, a temperate forest ecosystem. Concentrations of potassium (K), phosphorus (P) and nitrate (NO₃^-) in soil …

Providing Education To Enhance Wildlife Conservation In South Africa Through The First Wildlife School For Game Rancers - A Grassroots Effort By Government Authorized Conservationists, David L. Bergman, Nico Avenant, Francoais Schutte, Michael J. Bodenchuk

Wildlife Damage Management Conference

The establishment of the game ranching industry in South Africa has resulted in the conversion of 20 million hectares of marginal agricultural land to an economically viable and conservation oriented industry. The single biggest driving factor in the growth of the game ranching industry in South Africa was the promulgation of the Game Theft Act 105 of 1991 which conferred private ownership of game. Due to the Act, wildlife became economically viable and were managed according to the creation of this new market. The growth in game animals has reached its highest point since 1850 with over 20 million animals. …

Feral Horses Disrupt Greater Sage-Grouse Lekking Activity In The Great Basin, Peter S. Coates, Diana A. Munoz

Wildlife Damage Management Conference

Greater sage-grouse (Centrocercus urophasianus; hereafter, sage grouse) and feral horses (Equus ferus caballus) co-occur within Great Basin sagebrush ecosystems of western North America. In recent decades, sage-grouse populations have declined substantially while concomitantly feral horse populations have increased drastically. Although multiple studies have reported feral horses adversely impacting native ungulate species, direct interactions between feral horses and sage-grouse have not been documented previously. We compiled sage-grouse lek count data and associated ungulate observations from 2010 and 2013-2018. We used Bayesian multinomial logistic models to examine the response of breeding male sage-grouse to presence of native (i.e. …

Are Mountain Lions Really Eating Feral Horses?, Pat Jackson

Wildlife Damage Management Conference

In May 2018, the New York Times published an article titled, “Let Mountain Lions Eat Horses.” The article implies mountain lions (Puma concolor) either currently do or could limit feral horse (Equus caballus) populations across the Intermountain West. This claim, among others in the article, is not well documented in existing literature. As of March 1, 2018, the Bureau of Land Management estimated feral horse and burro populations in the western United States numbered almost 82,000 animals. I will briefly cover the evolution, extinction, and the reintroduction of feral horses to North America, their ecological effects, …

Feral Swine Disease Surveillance – National Targets And Pilot Projects, Vienna R. Brown, Rachel M. Maison, Thomas Gidlewski

Wildlife Damage Management Conference

The National Feral Swine Damage Management Program (NFSP) in collaboration with the National Wildlife Disease Program (NWDP) and USDA APHIS Veterinary Services works to identify the diseases of national concern in feral swine. The current national disease surveillance program includes classical swine fever (CSF), swine brucellosis (SB), and pseudorabies (PRV). CSF is a foreign animal disease and feral swine samples collected and tested serve as part of Veterinary Services surveillance stream for this pathogen. Both SB and PRV have been eradicated from U.S. commercial swine operations; however, as they are endemic diseases in feral swine populations, monitoring of feral swine …

Identifying The Next Conflict Wildlife Species, Angeline Scotten

Wildlife Damage Management Conference

The Florida Fish and Wildlife Conservation Commission (FWC) has recognized that wildlife conflict is of increasing concern among Floridians. Calls to the FWC regarding questions and apprehension of a multitude of species has increased dramatically over the state in the past decade; so much so that the agency has dedicated staff in each regional office to triage these issues. Historically, the agency had collected data reflecting the amount of complaints regarding species such as alligators and bears; complaints on other species received limited documentation, until recently. In April 2015, the agency implemented a new tracking system called the Wildlife Incident …

The National Feral Swine Program, National Strategy – The First Five Years, Michael C. Marlow, Vienna R. Brown, Dale L. Nolte

Wildlife Damage Management Conference

In 2014, through Congressional direction, the Animal Plant Health Inspection Service (APHIS) National Feral Swine Damage Management Program was created. While feral swine damage management was certainly not new to APHIS Wildlife Services, this mandate enabled a programmatic and unified approach in combating the destructive forces of feral swine throughout the United States and its territories. Recognizing the variance in environmental conditions and regulatory processes throughout the states, APHIS’ strategy is to provide resources and expertise at a national level, while allowing flexibility to manage operational activities from a local or state perspective. Having completed the first five years of …

You Are The Speaker: Considerations Of The Art And Science Of An Effective Presentation, George R. Gallagher

Wildlife Damage Management Conference

Effective communication is often stated as a key component to success in many aspects related to wildlife damage management. The objective of this presentation is to provide considerations of the components that can lead to an efficient and effective delivery of the desired messages. Clearly accepting the constraints of the presentation related to the audience and time available is the first step. Understanding that most effective presentations rarely have more than three “take-home messages” can be critical. Those messages must be clearly defined and refined.Observing and accounting for typical physical and environmental conditions that influence audio-visual technology should be considered. …

Effects Of Common Ravens On Greater Sage-Grouse In The Great Basin, Region, Usa, Peter S. Coates, Shawn T. O'Neil, Joseph L. Atkinson, Brianne E. Brussee, Pat J. Jackson, David J. Delehanty

Wildlife Damage Management Conference

Anthropogenic modification to ecosystems can result in the redistribution of species at higher trophic levels. Humans have re-organized predator-prey dynamics, namely by removing top predators and subsidizing more generalist mesocarnivore species. As a result, some mid-level predator species have increased in abundance and distribution, often to the detriment of lower-level species that are not adapted to increased predation rates. One example of a native avian predator that has experienced population increase following increased anthropogenic subsidization is the common raven (Corvus corax; hereafter, raven).The raven is an ubiquitous predator within sagebrush ecosystems in the western U.S.,and may contribute to …

Efficacy Of An Avian Repellent Applied Using Drop Nozzle-Equipped Ground Rigs In Reducing Blackbird Damage To Sunflower, Page E. Klug, Michael H. Ostlie, Scott J. Werner

Wildlife Damage Management Conference

In North Dakota large flocks of blackbirds feed on ripening crops, after breeding and prior to migration, resulting in an annual damage estimate averaging $3.5 million for sunflower. Since the repellent needs to be ingested to be effective, one obstacle is applying sufficient repellent directly to the sunflower face. Thus, we tested efficacy of an anthraquinone-based repellent when applied via drop-nozzle to sunflower using enclosed blackbirds in a semi-natural field setting. We used a ground-rig equipped with 360 Undercover^® drop nozzle sprayers to apply 20 gal/ac of solution to sunflower plots with a product application rate of 1.0 gal/ac …

Comparison Of Three Drug Combinations For Raccoon Immobilization, Shylo R. Johnson, Christine K. Ellis, Chad K. Wickham, Molly R. Selleck, Pauline Nol, Amy T. Gilbert

Wildlife Damage Management Conference

Raccoons (Proycon lotor) are regularly handled for damage management and research objectives. Safe handling of these animals in the field requires drug combinations that provide effective and predictable results with high safety margins for both the animal and personnel handling the animal, but also have a low probability of abuse. United States Drug Enforcement Administration scheduling relates to the probability of a drug being abused; class I drugs are associated with the greatest potential for abuse. We compared three drug combinations: butorphanol-azaperone-medetomidine (BAM; class IV), nalbuphine-azaperone-medetomidine (NAM; unscheduled), and ketamine-xylazine (KX; class III). Through a dose titration process, …

Using Unmanned Aerial Vehicles For Bird Harassment On Fish Ponds, Ciera A. Rhoades, Peter J. Allen, D. Tommy King

Wildlife Damage Management Conference

The effects of aquaculture decline on piscivorous birds in the Mississippi Delta concern catfish farmers, with possible increases in fish loss and disease transmission. Piscivorous birds quickly habituate to most current methods of harassment (loud noises and visual disturbances) leading to increased depredation and disease. Our study was designed to test the efficacy of using unmanned aerial vehicles (UAVs) to effectively control piscivorous birds at fish farms. We hypothesized that a UAV would be more efficient at reducing the number of fish-eating birds on fish ponds than current forms of harassment. We conducted pre-treatment bird surveys, harassment observations, and post-treatment …

Kaput® Feral Hog Bait Containing 0.005% Warfarin: An Overview Of Its Usefulness Against Feral Hogs And Safety To Wildlife And Humans, Richard M. Poche', David M. Poche', Gregory A. Franckwoiak, Tyler Clark, Larisa Polyakova, Batchimeg Tseveenjav

Wildlife Damage Management Conference

Warfarin has been approved for use in the United States as a rodenticide since 1948. The United States Environmental Protection approved Kaput^® Feral Hog Bait (0.005% warfarin) for use as a toxicant to control wild pigs in 2017. The level of warfarin is 80% less than in commercial rodenticide formulations. Since 1994 we have conducted wildlife safety studies examining the potential effects of warfarin on non-target mammals and birds. Over a 25-year period, non-target toxicity research was completed with European ferrets, pied magpies, mallard ducks, bobwhite quail, Norway rats, house mice, and American alligator to assess primary and secondary …
