Yellow-Throated Warbler In Scotts Bluff County, Nebraska, Mark A. Brogie, Bill F. Huser, Jerry Probst Dec 2023

Yellow-Throated Warbler In Scotts Bluff County, Nebraska, Mark A. Brogie, Bill F. Huser, Jerry Probst

Nebraska Bird Review

Yellow-throated Warbler (Setophaga dominica) is a rare to uncommon migrant in eastern and central Nebraska. It is possibly a regular breeder locally at sites containing sycamores in several southeastern Nebraska counties bordering the Missouri River. There are few Nebraska reports after July, with more reports November–January than August–October. This species has three previous documented Nebraska Panhandle records, all from May.

1. One photographed 26 May 2009, at Crescent Lake NWR, Garden Co.

2. One seen and “well described” 06 May 1931, at Antioch, Sheridan Co.

Analysis Of Mitochondrial Dna Sequence Data Demonstrates That Monophyly Of Myotis Occultus Is Complicated By Greater Sampling Of Myotis Lucifugus, Jeffrey M. Lorch, Daniel R. Taylor, Antoinette J. Piaggio Dec 2023

Analysis Of Mitochondrial Dna Sequence Data Demonstrates That Monophyly Of Myotis Occultus Is Complicated By Greater Sampling Of Myotis Lucifugus, Jeffrey M. Lorch, Daniel R. Taylor, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Abstract

The validity of Myotis occultus as a species unique from Myotis lucifugus has been a source of debate. Most recently, many authorities treat M. occultus as a distinct species, at least in part because a previous study showed that M. occultus and M. l. carissima (the subspecies that occurs in closest geographic proximity to M. occultus) form separate monophyletic clades based on sequences of two mitochondrial genes (cytochrome-b [cytb] and cytochrome oxidase subunit II [COII]). We re-evaluated the phylogenetic relationship between M. occultus and M. lucifugus based on mitochondrial sequences …

Nou Founding Ornithologist, Hypnotist, Physician: Isador Trostler, Rick Wright

Nebraska Bird Review

Eminent radiologist Benjamin H. Orndoff, eulogizing an esteemed colleague some months after his death, noted that Isador Simon Trostler (1869–1957) “as a lad . . . became interested in ornithology and herpetology, sending accounts of his observations and explorations to natural history magazines up to the late [18]90s.” Understandably more interested in Trostler’s role as a “pioneer in radiology,” Orndoff had no more to say about the natural history pursuits of one of Nebraska’s most notable early ornithologists, one of the founders 125 years ago of the Nebraska Ornithologists’ Union.

Conversely, we birders have known little or nothing of Trostler’s …

Highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b underwent an explosive geographic expansion in 2021 among wild birds and domestic poultry across Asia, Europe, and Africa. By the end of 2021, 2.3.4.4b viruses were detected in North America, signifying further intercontinental spread. Here we show that the western movement of clade 2.3.4.4b was quickly followed by reassortment with viruses circulating in wild birds in North America, resulting in the acquisition of different combinations of ribonucleoprotein genes. These reassortant A(H5N1) viruses are genotypically and phenotypically diverse, with many causing severe disease with dramatic neurologic involvement in mammals. The proclivity of …

The zoonotic origin of the COVID-19 pandemic virus highlights the need to fill the vast gaps in our knowledge of SARS-CoV-2 ecology and evolution in non-human hosts. Here, we detected that SARS-CoV-2 was introduced from humans into white-tailed deer more than 30 times in Ohio, USA during November 2021-March 2022. Subsequently, deer-to-deer transmission persisted for 2–8 months, disseminating across hundreds of kilometers. Newly developed Bayesian phylogenetic methods quantified how SARS-CoV-2 evolution is not only three-times faster in white-tailed deer compared to the rate observed in humans but also driven by different mutational biases and selection pressures. The long-term effect of …

Highly pathogenic avian influenza viruses (HPAIVs) of subtype H5 of the Gs/GD/96 lineage remain a major threat to poultry due to endemicity in wild birds. H5N1 HPAIVs from this lineage were detected in 2021 in the United States (US) and since then have infected many wild and domestic birds. We evaluated the pathobiology of an early US H5N1 HPAIV (clade 2.3.4.4b, 2021) and two H5N8 HPAIVs from previous outbreaks in the US (clade 2.3.4.4c, 2014) and Europe (clade 2.3.4.4b, 2016) in chickens and turkeys. Differences in clinical signs, mean death times (MDTs), and virus transmissibility were found between chickens and …

United States Department of Agriculture Wildlife Services: Staff Publications

The movement ecology of raccoons varies widely across habitats with important implications for the management of zoonotic diseases such as rabies. However, the spatial ecology of raccoons remains poorly understood in many regions of the United States, particularly in the southeast. To better understand the spatial ecology of raccoons in the southeastern US, we investigated the role of sex, season, and habitat on monthly raccoon home range and core area sizes in three common rural habitats (bottomland hardwood, upland pine, and riparian forest) in South Carolina, USA. From 2018–2022, we obtained 264 monthly home ranges from 46 raccoons. Mean monthly …

Investigating the influences of single nucleotide polymorphisms (SNP) associated with conceptus death (CD) on day 16 of pregnancy could distinguish cows who have inferior value for fertility traits. We hypothesized that CD is associated with SNP genotypes that disrupt maternal recognition and lead to early pregnancy loss. RNA sequences from Holstein cow pregnancies (n = 15) with normal conceptuses (Norm) or CD were subjected to SNP discovery via Qiagen CLC Genomics Workbench. Selected SNP were based on previous fertility studies, differentially expressed genes within pregnancy development analyses and proximity to SNP associated with fertility traits in the Cattle QTL …

Skin Lipids Alone Enable Conspecific Tracking In An Invasive Reptile, The Argentine Black And White Tegu Lizard (Salvator Merianae), M. Rockwell Parker, Eric A. Tillman, Lauren A. Nazarian, Megan L. Barlowe, Julianna M. Lincoln, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

Locating potential mates in non-native habitats is one of the most important challenges faced by invasive vertebrate species. The Argentine black and white tegu lizard (Salvator merianae) is a major invasive reptile species in the contiguous United States and is rapidly expanding its range across Florida and the Southeast, in part due to inadequate management strategies and tools. Because a wide array of reptiles, especially squamates (snakes and lizards), have been well-studied for their reliance on chemical cues to locate conspecifics, our project aimed to isolate chemical cues from tegus and assess the ability of adult males and …

Spatial Ecology Of The Texas Alligator Lizard (Gerrhonotus Infernalis) In Blanco County, Texas, Corey M. Fielder, Wade A. Ryberg, Danielle K. Walkup, Jared M. Holmes, Toby J. Hibbitts

Western North American Naturalist

Texas Alligator Lizards (Gerrhonotus infernalis) range from Central Texas into adjacent northeastern Mexico, and published ecological studies on their terrestrial and arboreal movement patterns are lacking. We used radiotelemetry to assess movements, annual home range, and arboreal activity of G. infernalis at Bamberger Ranch Preserve, Blanco County, Texas, to provide baseline ecological data for populations occurring in the northernmost extent of the species’ range. Movement patterns were influenced by temporal (e.g., seasonal) and behavioral cues (e.g., breeding period), but generally no differences were observed between sexes. Annual home range varied, but males averaged larger 95% MCP (minimum convex …

Highly pathogenic avian influenza viruses (HPAIVs) of the A/goose/Guangdong/1/1996 lineage H5 clade 2.3.4.4b continue to have a devastating effect on domestic and wild birds. Full genome sequence analyses using 1369 H5N1 HPAIVs detected in the United States (U.S.) in wild birds, commercial poultry, and backyard flocks from December 2021 to April 2022, showed three phylogenetically distinct H5N1 virus introductions in the U.S. by wild birds. Unreassorted Eurasian genotypes A1 and A2 entered the Northeast Atlantic states, whereas a genetically distinct A3 genotype was detected in Alaska. The A1 genotype spread westward via wild bird migration and reassorted with North American …


Limited Accumulation And Persistence Of An Influenza A Virus In Tadpole Snails (Physa Spp.), Paul T. Oesterle, J. Jeffrey Root, Darcy S.O. Mora, Heather Schneider, Alan B. Franklin, Kathryn P. Huyvaert Oct 2023

Limited Accumulation And Persistence Of An Influenza A Virus In Tadpole Snails (Physa Spp.), Paul T. Oesterle, J. Jeffrey Root, Darcy S.O. Mora, Heather Schneider, Alan B. Franklin, Kathryn P. Huyvaert

United States Department of Agriculture Wildlife Services: Staff Publications

Waterfowl infected with avian influenza A viruses (IAVs) shed infectious virus into aquatic environments, providing a mechanism for transmission among waterfowl, while also exposing the entire aquatic ecosystem to the virus. Aquatic invertebrates such as freshwater snails are likely exposed to IAVs in the water column and sediment. Freshwater snails comprise a significant portion of some waterfowl species’ diets, so this trophic interaction may serve as a novel route of IAV transmission. In these experiments, tadpole snails (Physa spp.) were exposed to a low-pathogenicity IAV (H3N8) to determine whether snails can accumulate the virus and, if so, how long virus …

Effects Of Fire On Kangaroo Rats In The San Joaquin Desert Of California, David J. Germano, Lawrence R. Saslaw, Brian L. Cypher, Linda Spiegel

Western North American Naturalist

Fire can alter ecological communities, particularly those that are not fire-adapted, such as desert communities. We examined the effects of fire on rodent communities in the San Joaquin Desert of central California. Of particular interest were the effects on kangaroo rats (Dipodomys spp.) including 2 rare species, the giant kangaroo rat (D. ingens) and the short-nosed kangaroo rat (D. nitratoides brevinasus). Lightning caused multiple fires in arid scrub habitat in western Kern County in 1993. We trapped rodents at 7 sites along paired transects, with one transect in a burned area and one in a …

Nebraska Bird Review

On the morning of October 7, 2023, I observed Nebraska’s second Limpkin (Aramus guarauna) at Crystal Cove Park in South Sioux City, and the bird was subsequently seen by several other observers throughout that afternoon. Photo and video records were obtained (https://ebird.org/checklist/S151656716). The summer and fall of 2023 brought fourteen sightings to Iowa, though it is impossible to determine how many birds were involved (eBird, 2023). One of those sightings occurred in the northwestern part of the state at Bacon Creek Park in Sioux City when a single Limpkin was independently reported by two observers on …


Expanding The Role Of The Temporal Dimension In Ecological Niche Models: A Study On Mexican Montane Small Mammals, Gonzalo E. Pinilla Buitrago Sep 2023

Expanding The Role Of The Temporal Dimension In Ecological Niche Models: A Study On Mexican Montane Small Mammals, Gonzalo E. Pinilla Buitrago

Dissertations, Theses, and Capstone Projects

Ecological niche models (ENMs) are commonly used to estimate the potential geographic distributions of species and have various uses, such as predicting invasive species' potential distribution, assessing vulnerability to climate change, or estimating paleodistributions. However, ENM developments have primarily focused on solving spatially related issues, underemphasizing the temporal dimensionality of occurrence and environmental data collected over the last century. One limitation of ENMs is the common practice of using recent environmental averages that fail to capture the gradual environmental change over the time span of the occurrence records and can hide trends in environmental variables, a critical piece of information …

Clade 2.3.4.4b highly pathogenic avian influenza (HPAI) A(H5N1) viruses that are responsible for devastating outbreaks in birds and mammals pose a potential threat to public health. Here, we evaluated their susceptibility to influenza antivirals. Of 1,015 sequences of HPAI A(H5N1) viruses collected in the United States during 2022, eight viruses (∼0.8%) had a molecular marker of drug resistance to an FDA-approved antiviral: three adamantane-resistant (M2-V27A), four oseltamivir-resistant (NA-H275Y), and one baloxavir-resistant (PA-I38T). Additionally, 31 viruses contained mutations that may reduce susceptibility to inhibitors of neuraminidase (NA) (n = 20) or cap-dependent endonuclease (CEN) (n = 11). A panel of 22 …


Go Big Or Go Home: Divergence In Morphology And Behavior Between Island And Islet Populations Of The San Cristóbal Lava Lizard (Microlophus Bivittatus), Emilio J. Mancero Aug 2023

Go Big Or Go Home: Divergence In Morphology And Behavior Between Island And Islet Populations Of The San Cristóbal Lava Lizard (Microlophus Bivittatus), Emilio J. Mancero

Masters Theses

Rapid divergence in body size is a well-documented phenomenon among island species, associated with macroevolutionary processes of diversification and adaptive radiation. The effect of insularity in determining larger body size as an optimal phenotype is primarily attributed to lower predation and greater intraspecific competition on islands. Our study examined interpopulation variation in morphology, social behavior and predator avoidance in Galápagos lava lizards endemic to San Cristóbal island (Microlophus bivittatus), and the nearby islet Isla Lobos. Islet populations have fewer competitors than those on the island, where native and introduced predators are abundant. We simulated interactions with predators and …
