Northern Saw-Whet Owl Autumn Migration In Eastern Nebraska: Results From A Three-Year Banding Study, Stephen J. Brenner, Joel G. Jorgensen Dec 2021

Northern Saw-Whet Owl Autumn Migration In Eastern Nebraska: Results From A Three-Year Banding Study, Stephen J. Brenner, Joel G. Jorgensen

Nebraska Bird Review

Prior to 2019, records of NSWOs in Nebraska during fall were limited. There were fewer than five accepted reports in eastern Nebraska since the 1950s (Silcock and Jorgensen, 2021). The Hitchcock banding station along the Missouri River bluffs in nearby western Iowa has captured, banded, and released 20-50 birds during autumn migration for a number of years (J. Toll, personal communication). Furthermore, a single season banding study in central Nebraska during fall 2004 captured 14 NSWOs (Kim 2005), suggesting the species may migrate annually over much of the state in fall, or at least in more years than previously thought. …

Mute Swan Observation At Gavins Point Dam Area, Cedar/Knox Co., Nebraska, Caleb Strand, Mark A. Brogie

Nebraska Bird Review

The Nebraska Ornithologists’ Union Records Committee (NOURC) considers Mute Swan (Cygnus olor) to be Accidental in Nebraska (NOURC 2017) with only two accepted records. A review of Mute Swan status in the Midwest and Nebraska, how individual records in Nebraska are evaluated to determine wild provenance, and a review of Nebraska reports can be found in “The Mute Swan in Nebraska: History and Current Status” (Brogie et al. 2016).

The following is an account of the third NOURC accepted record for Mute Swan in Nebraska. On 11 June 2021 we observed two sub-adult Mute Swans on Lake Yankton, Cedar County, …


Boxed In: Hinge Closing Performance Of Ornate Box Turtles (Terrapene Ornata), Gina L. Buelow Dec 2021

Boxed In: Hinge Closing Performance Of Ornate Box Turtles (Terrapene Ornata), Gina L. Buelow

Graduate Theses/Dissertations

Turtles are perhaps best known for the bony shells that encase them, a unique morphological trait that provides protection against predators. Many taxa have even evolved the ability to enclose themselves using hinges that can be used to create a seal between the carapace and plastron. I measured the hinge closing force of Ornate Box Turtles (Terrapene ornata) to assess the performance of this unusual yet ecologically important trait. I sampled head-started turtles from Thomson Sand Prairie in the Upper Mississippi River National Wildlife and Fish Refuge and wild turtles collected in northern Oklahoma. To assess the effects of head-starting …


Review Of Nest Records Of Nebraska Birds By Wayne J. Mollhoff, W. Ross Silcock Dec 2021

Review Of Nest Records Of Nebraska Birds By Wayne J. Mollhoff, W. Ross Silcock

Nebraska Bird Review

This book summarizes a lifetime of investigation of Nebraska’s breeding birds by Wayne Mollhoff. Even though I say the book summarizes a lifetime of investigation, I would not be surprised if Wayne resurfaces in a few years with a follow-up of some sort, intrepid investigator that he is. Over the years Wayne has spent innumerable days in the field climbing trees in full forestry gear, wading and kayaking marshes and rivers, hiking over prairies, and bushwhacking through dense forests (there are still a few in Nebraska). But this isn’t the totality of Wayne’s talents; he is a determined researcher with …

Fall Field Report, August-November 2021, W. Ross Silcock

Nebraska Bird Review

INTRODUCTION Recent years have seen increasing reports of birds lingering quite late, and this fall was no exception. Notable groups exhibiting tardy departures were shorebirds and vireos. Tardy shorebirds were record late Solitary Sandpipers, near-record late Dunlin, and late Long-billed Curlew, Ruddy Turnstone, Least and Semipalmated Sandpipers, Long-billed Dowitcher, and Wilson’s Phalarope. Among the vireos, all regular species were at least tardy; record late was a Red-eyed Vireo, a Warbling Vireo was record late for the Panhandle, and a Blue-headed Vireo was second latest on record. Record late was a Barn Swallow, and a Mountain Bluebird was record late in …

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

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 …

Towards A More Comprehensive Understanding Of Wild Pig (Sus Scrofa) Impacts On Agricultural Producers: Insights From A Texas Case Study, Keith M. Carlisle, Nicole Didero, Sophie Mckee, Julie Elser, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

This research investigates the impacts of invasive wild pigs (Sus scrofa Linneaus) on agricultural producers in Texas, with the aim of identifying and describing all categories of wild pig impacts and quantifying the extent of producers’ over- or underestimation of their total wild pig-related costs in 2018, as compared to calculations based upon data subsequently provided by the producers about individual wild pig-related costs and losses. Based on interviews with 23 producers in 16 Texas counties, we identified more than 20 discrete categories of negative impacts and negligible positive impacts associated with wild pigs. Among them were categories that have …

Landscape Transformations Produce Favorable Roosting Conditions For Turkey Vultures And Black Vultures, Jacob E. Hill, Kenneth F. Kellner, Bryan M. Kluever, Michael L. Avery, John S. Humphrey, Eric A. Tillman, Travis L. Devault, Jerrold L. Belant

United States Department of Agriculture Wildlife Services: Staff Publications

Recent increases in turkey vulture (Cathartes aura) and black vulture (Coragyps atratus) populations in North America have been attributed in part to their success adapting to human-modified landscapes. However, the capacity for such landscapes to generate favorable roosting conditions for these species has not been thoroughly investigated. We assessed the role of anthropogenic and natural landscape elements on roosting habitat selection of 11 black and 7 turkey vultures in coastal South Carolina, USA using a GPS satellite transmitter dataset derived from previous research. Our dataset spanned 2006–2012 and contained data from 7916 nights of roosting. Landscape …

Reproductive Success Of Captive-Reared Allegheny Woodrats (Neotoma Magister) Released Into Genetically Depauperate Populations, Miracle M. Davis, Timothy J. Smyser, Scott A. Johnson, Joseph Duchamp, Jeffery L. Larkin, Robert K. Swihart, Jacqueline M. Doyle

United States Department of Agriculture Wildlife Services: Staff Publications

Habitat fragmentation and degradation have led to a proliferation of small and isolated populations that are vulnerable to genetic erosion. Reduction in habitat and concomitant declines in population connectivity can expediate the collapse of species that exist as natural metapopulations. In recent years, Allegheny woodrats (Neotoma magister) have experienced local extirpations and declines in genetic diversity across their range due to disease-related mortality, reduced food availability, and disruption of connectivity among subpopulations. In response, we developed a captive-breeding program to facilitate genetic management of isolated woodrat populations in Indiana. Between 2010 and 2012, 27 captive-reared individuals were released to four …


Economic Estimates Of Wild Hog (Sus Scrofa) Damage And Control Among Young Forest Plantations In Alabama, Micah Fern, Rebecca Barlow, Chris Slootmaker, John Kush, Stephanie Shwiff, Larry Teeter, Jim Armstrong Dec 2021

Economic Estimates Of Wild Hog (Sus Scrofa) Damage And Control Among Young Forest Plantations In Alabama, Micah Fern, Rebecca Barlow, Chris Slootmaker, John Kush, Stephanie Shwiff, Larry Teeter, Jim Armstrong

United States Department of Agriculture Wildlife Services: Staff Publications

Operating as ecological engineers, the increased distribution and abundance of wild hogs (Sus scrofa) has caused considerable socio-economic impacts. The international scope of economic research providing wild hog damage estimates are often confined to agricultural crops, while damage estimates among forest plantations are lacking. In Alabama, private landowners hold the majority of timberland acreage and are less equipped to absorb financial losses from wild hog damage than their industrial counterparts. A survey was conducted to estimate the economic impact of wild hogs, namely costs of damage and control, to privately owned forestlands. The survey was distributed in the …


Sex And Nest Type Influence Avian Blood Parasite Prevalence In A High-Elevation Bird Community, Marina D. Rodriguez, Paul F. Doherty, Antoinette J. Piaggio, Kathryn P. Huyvaert Dec 2021

Sex And Nest Type Influence Avian Blood Parasite Prevalence In A High-Elevation Bird Community, Marina D. Rodriguez, Paul F. Doherty, Antoinette J. Piaggio, Kathryn P. Huyvaert

United States Department of Agriculture Wildlife Services: Staff Publications

Background: The prevalence of avian haemosporidian parasites and the factors influencing infection in the Colorado Rocky Mountains are largely unknown. With climate change expected to promote the expansion of vector and avian blood parasite distributions, baseline knowledge and continued monitoring of the prevalence and diversity of these parasites is needed.

Methods: Using an occupancy modeling framework, we conducted a survey of haemosporidian parasite species infecting an avian community in the Colorado Rocky Mountains in order to estimate the prevalence and diversity of blood parasites and to investigate species-level and individual-level characteristics that may influence infection.

Results: We estimated the prevalence …

Responses Of Turkey Vultures To Unmanned Aircraft Systems Vary By Platform, Morgan B. Pfeiffer, Bradley F. Blackwell, Thomas W. Seamans, Bruce N. Buckingham, Joshua L. Hoblet, Patrice E. Baumhardt

United States Department of Agriculture Wildlife Services: Staff Publications

A challenge that conservation practitioners face is manipulating behavior of nuisance species. The turkey vulture (Cathartes aura) can cause substantial damage to aircraft if struck. The goal of this study was to assess vulture responses to unmanned aircraft systems (UAS) for use as a possible dispersal tool. Our treatments included three platforms (fixed-wing, multirotor, and a predator-like ornithopter [powered by flapping flight]) and two approach types (30 m overhead or targeted towards a vulture) in an operational context. We evaluated perceived risk as probability of reaction, reaction time, flight-initiation distance (FID), vulture remaining index, and latency to return. …

Potential Use For Serosurveillance Of Feral Swine To Map Risk For Anthrax Exposure, Texas, Usa, Rachel M. Maison, Courtney F. Pierce, Izabela K. Ragan, Vienna R. Brown, Michael J. Bodenchuk, Richard A. Bowen, Angela M. Bosco-Lauth

United States Department of Agriculture Wildlife Services: Staff Publications

Anthrax is a disease of concern in many mammals, including humans. Management primarily consists of prevention through vaccination and tracking clinical-level observations because environmental isolation is laborious and bacterial distribution across large geographic areas diffi cult to confi rm. Feral swine (Sus scrofa) are an invasive species with an extensive range in the southern United States that rarely succumbs to anthrax. We present evidence that feral swine might serve as biosentinels based on comparative seroprevalence in swine from historically defi ned anthrax-endemic and non–anthraxendemic regions of Texas. Overall seropositivity was 43.7% (n = 478), and logistic regression revealed county endemicity …


Amphibians And Reptiles As Prey Of Heteroctenus Junceus (Scorpiones: Buthidae), With A Summary Of Vertebrate Predation By Scorpions In The West Indies, Tomás M. Rodríguez-Cabrera,, Ernesto Morell Savall, Rolando Teruel Nov 2021

Amphibians And Reptiles As Prey Of Heteroctenus Junceus (Scorpiones: Buthidae), With A Summary Of Vertebrate Predation By Scorpions In The West Indies, Tomás M. Rodríguez-Cabrera,, Ernesto Morell Savall, Rolando Teruel

Euscorpius

Vertebrate predation by scorpions has been scarcely documented in the literature. Contrary to large scorpions of the genera Centruroides, Hadrurus, Opistophthalmus, and Pandinurus from North America and Africa, which are capable of subduing even small rodents and bats, West Indian scorpions of the genera Centruroides, Heteroctenus, and Tityus seem to limit their prey to amphibians and reptiles. Herein we present new cases of a frog (Osteopilus septentrionalis; Hylidae) and three lizards (Anolis allisoni, A. ophiolepis, and A. sagrei; Dactyloidae) preyed upon by Heteroctenus junceus (Herbst, 1800), at the time we summarize all cases of vertebrate …


How Do Genetic Relatedness And Spatial Proximity Shape African Swine Fever Infections In Wild Boar?, Tomasz Podgórski, Kim M. Pepin, Anna Radko, Angelika Podbielska, Magdalena Łyjak, Grzegorz Woźniakowski, Tomasz Borowik Nov 2021

How Do Genetic Relatedness And Spatial Proximity Shape African Swine Fever Infections In Wild Boar?, Tomasz Podgórski, Kim M. Pepin, Anna Radko, Angelika Podbielska, Magdalena Łyjak, Grzegorz Woźniakowski, Tomasz Borowik

United States Department of Agriculture Wildlife Services: Staff Publications

The importance of social and spatial structuring of wildlife populations for disease spread, though widely recognized, is still poorly understood in many host-pathogen systems. In particular, system-specific kin relationships among hosts can create contact heterogeneities and differential disease transmission rates. Here, we investigate how distance-dependent infection risk is influenced by genetic relatedness in a novel host-pathogen system: wild boar (Sus scrofa) and African swine fever (ASF).We hypothesized that infection risk would correlate positively with proximity and relatedness to ASF-infected individuals but expected those relationships to weaken with the distance between individuals due to decay in contact rates and …

How biotic and abiotic factors act together to shape biological diversity is a major question in evolutionary biology. The recent availability of large datasets and development of new methodological approaches provide new tools to evaluate the predicted effects of ecological interactions and geography on lineage diversification and phenotypic evolution. Here, we use a near complete phylogenomic-scale phylogeny and a comprehensive morphological dataset comprising more than a thousand specimens to assess the role of biotic and abiotic processes in the diversification of monitor lizards (Varanidae). This charismatic group of lizards shows striking variation in species richness among its clades and multiple …

The First Troglobitic Scorpions From Hispaniola, Greater Antilles: Two New Species Of Cazierius Francke, 1978 (Scorpiones: Diplocentridae), Rolando Teruel, Solanlly Carrero Jiménez, Gabriel De Los Santos

Euscorpius

Two new species of the Greater Antillean endemic scorpion genus Cazierius Francke, 1978, are herein described from the island of Hispaniola. They were found inside isolate limestone caves in the Dominican Republic and are fully troglomorphic, thus, apparently being strict troglobites that represent the first ever documented for this genus. The present additions raise the number of Hispaniolan species of both Cazierius and the family Diplocentridae Karsch, 1880, to five and ten, respectively.


Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt Nov 2021

Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt

Biology ETDs

Comparative phylogeography has historically been defined as the study of how genetic variation of co-distributed species has been shaped by biogeographical history. This is a mature field of study out of which several techniques have been developed directed at identifying the role ecology and geography in diversification patterns across time. I employ the tools developed in classical comparative phylogeography across multiple taxonomic scales and across regions that historically have been understudied. My first two chapters study the complex history of host-switching, codiversification, and reassortment of hantaviruses in their mammal hosts across North America. By taking a host-centric comparative phylogeographic approach …


The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel Nov 2021

The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel

Euscorpius

The Mexican scorpion Centruroides hoffmanni Armas, 1996 was described on the basis of a supposed adult female (actually a juvenile) from La Gloria, Arriaga Municipality, southwest of the Chiapas State. In its redescription, this species was also recorded from the southeastern of Oaxaca State. Nevertheless, in the recent revision of the “thorellii” species-group of the genus Centruroides Marx, 1890, a new species from Chiapas was misidentified as C. hoffmanni and, also, an erroneous new diagnosis was given for C. hoffmanni. In the present contribution, this new species is named Centruroides concordia sp. n., and the correct identity of C. …

Cetacean Acousticwelfare In Wild And Managed-Care Settings: Gaps And Opportunities, Paige E. Stevens, Heather Hill, Jason N. Bruck

Faculty Publications

Cetaceans are potentially at risk of poor welfare due to the animals’ natural reliance on sound and the persistent nature of anthropogenic noise, especially in the wild. Industrial, commercial, and recreational human activity has expanded across the seas, resulting in a propagation of sound with varying frequency characteristics. In many countries, current regulations are based on the potential to induce hearing loss; however, a more nuanced approach is needed when shaping regulations, due to other non-hearing loss effects including activation of the stress response, acoustic masking, frequency shifts, alterations in behavior, and decreased foraging. Cetaceans in managedcare settings share the …

Rooting Out Genetic Structure Of Invasive Wild Pigs In Texas, Anna M. Mangan, Antoinette J. Piaggio, Michael J. Bodenchuk, Courtney F. Pierce, Timothy J. Smyser

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive wild pigs (Sus scrofa), also called feral swine or wild hogs, are recognized as among the most destructive invasive species in the world. Throughout the United States, invasive wild pigs have expanded rapidly over the past 40 years with populations now established in 38 states. Of the estimated 6.9 million wild pigs distributed throughout the United States, Texas supports approximately 40% of the population and similarly bears disproportionate ecological and economic costs. Genetic analyses are an effective tool for understanding invasion pathways and tracking dispersal of invasive species such as wild pigs and have been used recently …


Wildlife Responses To Livestock Guard Dogs And Domestic Sheep On Open Range, Daniel Kinka, Jeffrey T. Schultz, Julie K. Young Nov 2021

Wildlife Responses To Livestock Guard Dogs And Domestic Sheep On Open Range, Daniel Kinka, Jeffrey T. Schultz, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

Domestic sheep (Ovis aries) are an attractant to carnivores; however, sheep are often accompanied by humans and livestock guardian dogs (LGDs; Canis familiaris), which defend sheep from depredation. Sheep also compete directly with wildlife for grazing resources. Although practiced for millennia in much of the world outside North America, the effect that transhumance has on wildlife is poorly understood. To test the effect of sheep bands (sheep, humans, and LGDs) on wildlife, we modeled the detection probability of wild mammals relative to the presence of sheep bands in the Northwestern United States. Sheep band presence was associated …

During 2019–2020, the Virgin Islands Department of Health investigated potential animal reservoirs of Leptospira spp., the bacteria that cause leptospirosis. In this cross-sectional study, we investigated Leptospira spp. exposure and carriage in the small Indian mongoose (Urva auropunctata, syn: Herpestes auropunctatus), an invasive animal species. This study was conducted across the three main islands of the U.S. Virgin Islands (USVI), which are St. Croix, St. Thomas, and St. John. We used the microscopic agglutination test (MAT), fluorescent antibody test (FAT), real-time polymerase chain reaction (lipl32 rt-PCR), and bacterial culture to evaluate serum and kidney specimens and compared the …


Importance Of Woodland Patches As Hibernacula For Gartersnakes In A Prairie River Floodplain Of Central Nebraska, Tony Bridger, Keith Geluso Oct 2021

Importance Of Woodland Patches As Hibernacula For Gartersnakes In A Prairie River Floodplain Of Central Nebraska, Tony Bridger, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Gartersnakes are common inhabitants along prairie rivers in the Great Plains, but little information is known about hibernacula among diverse floodplain habitats. We radio-tracked Common Gartersnakes (Thamnophis sirtalis) and Plains Gartersnakes (Thamnophis radix) to hibernacula on islands in a braided river system subject to frequent environmental changes along the Platte River in central Nebraska. We further examined capture rates of gartersnakes in floodplain woodland patches from June to November to examine seasonal use of this habitat. In early and mid-September, movements of snakes with transmitters were in grasslands. From late September to mid-October, the farthest movements …
