Advancing Butterfly Systematics Through Genomic Analysis, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Within the framework of an ongoing comparative genomic study of global butterfly diversity, we construct phylogenetic trees combining all protein-coding genes assembled from the whole genome shotgun data. When viewed in the context of current taxonomy and phenotypic knowledge, the genome-wide phylogeny points to further advances in butterfly systematics, which are presented here. We assign major clades with comparable levels of genetic divergence to the same taxonomic rank and apply criteria involving relative population divergence and gene flow to define species boundaries. As a result, one genus, 13 subgenera, 62 species, and five subspecies are proposed as new (type species …

Modifying The Comb, Rethinking The Install: Integrated Approaches To Honey Bee Colony Establishment And Winter Survival, Shelby A. Kittle

Department of Entomology: Dissertations, Theses, and Student Research

The European, or Western honey bee (Apis mellifera L.) plays a vital role in global ecosystems and agriculture, providing essential pollination services and producing valuable hive products. However, honey bee colony losses have escalated worldwide, but particularly across the United States due to various stressors, including biotic and abiotic factors, mismanagement, and environmental challenges. This thesis investigates key challenges in honey bee management and explores solutions aimed at improving colony health and productivity.

Chapter 1 provides an overview of the beekeeping industry, detailing its economic importance, services, and products, as well as the many challenges faced by beekeepers. It …

Epidemiological Inferences Of The Impacts Of Winter Ticks On Moose Health, Krishna S. Woerheide

Department of Entomology: Dissertations, Theses, and Student Research

The North American Moose (mooz in Anishinaabemowin, Ojibwe language, Alces alces), a culturally significant subsistence species for the Anishinaabe people, faces population decline due to calf predation, pathogen transmission, and parasitism by the winter tick (Dermacentor albipictus), all exacerbated by climate change. This study explores the impact of winter tick infestations on moose health, with a focus on natural mineral seeps as potential transmission hotspots in moose habitats within the Grand Portage Indian Reservation (Gichi Onigaming), on Isle Royale National Park (Minong), and within the 1854 Ceded Territory (greater northeastern Minnesota) - ancestral and present homelands of …

Ediacaran Paleocommunity Structure, Body Size Evolution, And The Rise Of Complex Animals, Matthew Philip Craffey

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The Ediacaran period (635-538ma) is a key interval in the evolution of life as it records the first macroscopic animal communities. Major extinction pulses appear to have altered the composition of the global marine biosphere between each sub-interval of the Ediacaran Period: the Avalon, White Sea, and Nama assemblage Zones. While considerable attention has been paid to the causes of these extinction pulses, less has been afforded to the consequences of Ediacaran biotic turnover for community organization and function. Moreover, it is unclear how body size - the defining trait of macrofauna - affected the transition between animal groups across …

Influence Of Biotic And Abiotic Factors On Decomposition And The Determination Of Time Since Death: Applications Of Forensic Entomology And Taphonomy, John Oladapo Obafunwa

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The determination of the postmortem interval (PMI) is essential for the investigation and successful prosecution of suspected cases of homicide. While the forensic pathologist might be able to draw fairly accurate conclusions during the initial 24–36 hours, beyond this period, the assistance of other experts like forensic entomologists and taphonomists would be required. The present study was designed to observe the postmortem changes in Sus scrofa placed in a cage in Nebraska, located in the American Central Great Plains. The setting is in an open grassland in late spring to early summer. The observed variables with respect to biotic and …

Spatial Ecology And Predator–Prey Interactions Of Mountain Lions In California's San Francisco North Bay, Jacob A. Harvey

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

Understanding spatial ecology and predator-prey interactions are central to wildlife ecology and conservation. We tracked mountain lions with GPS telemetry to evaluate space use, predator-prey interactions, and resource selection in California’s San Francisco North Bay, USA. In Chapter 1, we evaluated the influence of human disturbance on home range size, prey composition, and kill rates on black-tailed deer (Odocoileus hemionus columbianus) across an urban-rural gradient. Both males and females increased home range size with increasing development at low to moderate levels of development, but female home range size stabilized across greater proportions of development while male home range …

Maggot Mass Effect On The Development And Survival Of Forensic Blow Flies, Akomavo Fabrice Gbenonsi

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

Forensic entomology scientists use blow flies' developing patterns to estimate the postmortem interval (PMI). However, larval aggregations produce metabolic heat, resulting in complex microclimates that may change growth timetables. This study investigates how larval density and associated temperature changes affect the development and survival of two forensically essential blow fly species, Lucilia sericata and Calliphora vicina.

This study examined how larval density and associated thermal profiles affect the development of both blow fly species. Using a split-plot design, we tested four larval densities at 25°C and 30°C, with temperature gradients measured via thermocouple at four mass positions three times …

Walleye And Sauger Movement And Entrainment In Lewis And Clark Lake, William Joseph Radigan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Walleye Sander vitreus and Sauger Sander canadensis are both socioeconomically important sportfish species in Lewis and Clark Lake, an interjurisdictionally managed mainstem Missouri River reservoir fishery. Since 2011, adult catch per unit effort (CPUE) of both Walleye and Sauger has remained at approximately 50% of pre-2011 levels. A presumed reason for the suppressed CPUE of adult Walleye and Sauger is substantial entrainment of larval and adult fish resulting from the reservoir’s high turnover rate (7.2 d). Acoustic telemetry was used to quantify adult movement and entrainment and ichthyoplankton trawls were used to assess larval entrainment. Relative importance of factors driving …

Landscape Effects On The Beneficial Arthropod Community In Agriculturally Dominated Environments, Hannah E. Stowe

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ecosystem services in agriculturally dominated regions rely, at least in part, on arthropods. Environment and biodiversity influence beneficial arthropods in population size, community structure, diversity, and ecosystem service provisioning. Predation is among the most important services provided by arthropods in agroecosystems. Understanding what alters predation and predator activity can support the successful application of biological control and, more broadly, integrated pest management. Land use and edge adjacency, field characteristics, landscape, seasonality, and diel period all alter predatory behavior. Crop fields dominate Nebraska agroecosystems, although interspersed perennial grasslands persist through the Conservation Reserve Program (CRP). Such grasslands supply crucial resources and …

Stereotypic Behaviors And Physiological Indicators Of Stress Occur In Horses With Restricted Durations Of Turnout, Elizabeth E. Rodgers

Department of Animal Science: Dissertations, Theses, and Student Research

The confinement of horses to stalls with limited or no turnout time restricts their natural roaming behaviors, which potentially increases stress and behavioral stereotypies. This study investigated the impact of turnout duration on behavioral and physiological stress indicators in healthy horses. Adult horses (n = 11) were enrolled in a 3 treatment (0-, 15-, and 60-minute turnout/day) Latin square design, including 3 12 d experimental periods over 6 weeks. Horses were acclimated to turnout (24.38 x 64.01m indoor arena) and stalls (2.74 x 4.87m - 3.66 x 3.66m) stalls prior to data collection on day 1. Experienced handlers managed …

Restoring Exotic Cool-Season Grass Dominated Landscapes With Clethodim And Glyphosate, Eleanor J. Muzzy, Joshua D. Wiese, Abraham J. Kanz

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A major threat to grasslands around the world is the spread of exotic cool-season grasses (ECSG). ECSG dominate vegetative communities and degrade critical habitats. One of the most common methods to treat ECSG is herbicide. To compare how the widely-used, non-specific herbicide glyphosate compared to the grass-specific herbicide clethodim, we conducted a fall spray in November 2023 at two different sites located in the Central Platte River Valley of Nebraska. The following June, we used a modified Daubenmire frame sampling method to gather data on relative cover, species richness, and community composition. After analysis, glyphosate appeared to be more effective …

2024–2025 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

For the second year in a row, all twenty CBCs [Christmas Bird Counts] were run during the 2024–2025 season. The weather was generally cooperative, although five circles reported fog and two others had rain. Branched Oak-Seward was postponed a week due to icy conditions on the originally scheduled day. The average high temperature for all circles on count day was 41 and the average low temperature was 22. Because December had remained relatively mild, there was a good deal of open water, which encouraged many species of water birds to remain. Consequently, most of the circles reported species totals higher …

Winter Field Report, December 2024–February 2025, W. Ross Silcock

Nebraska Bird Review

Since I started a few years ago to compare each season’s reports with the status of each species as presented in BONO (Species Accounts – Birds of Nebraska – Online), I had expected that “Routine reports” would apply to an increasing number of species as the BONO database firmed up, but this hasn’t happened. My comments from last winter continue to be valid this winter, now for the third winter in a row: As was the case for winter 2022–2023, the big general story was the large number of reports of tardy fall migrants and unexpectedly northerly occurrences in mid-winter… …

Additional Geographic Records Of Dekay’S Brownsnake (Storeria Dekayi) In Nebraska, Including A Late Seasonal Observation And Likely Range Expansion, Lauren Bahe, Dan D. Fogell, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Dekay’s Brownsnake (Storeria dekayi) occurs across much of eastern North America, inhabiting diverse environments such as marshes, woodlands, woodland edges, and urban areas. In Nebraska, recent studies documented its presence beyond the extreme southeastern region of the state, indicating a potential range expansion to the west and north. Our study continues to update its distribution with four additional county records. Two counties, Franklin and Harlan, represent the farthest west observations for Dekay’s Brownsnake in the state, further indicating a likely westward expansion. An observation from 6 December 2023 also represents the latest seasonal observation in the state. Despite …

Exploring The Pathogen Profiles Of Ancient Feces, Drew Capone, David Holcomb, Amanda Lai, Karl Reinhard, Joe Brown

Karl Reinhard Publications

Analysis of ancient desiccated feces – termed paleofeces or coprolites – can unlock insights into the lives of ancient people. We collected desiccated feces from caves in the Rio Zape Valley in Mexico (725-920 CE). First, we extracted DNA with methods previously optimized for paleofeces. Then, we applied highly sensitive modern molecular tools (i.e., PCR pre-amplification followed by multi-parallel qPCR) to assess the presence of 30 enteric pathogens. We detected ≥1 pathogen associated gene in each of the ten samples and a mean of 3.9 pathogens per sample. The targets detected included Blastocystis spp. (n=7), atypical enteropathogenic E. coli (n=7), …

Correction On The Status Of Nematodes Pavidus Horn, 1886 (Coleoptera: Eucnemidae: Dromaeolinae: Dromaeolini), With Redescriptions Of Two Species From The Southeastern United States And The Caribbean, Robert L. Otto

Insecta Mundi

The status of Nematodes pavidus Horn (Coleoptera: Eucnemidae), in relation to Nematodes punctatus LeConte and Nematodes teres Horn is being questioned after Muona (2000) revised the family in the Nearctic region. Investigations into the status of N. pavidus included explorations of the histories among these three species and examining images of the types through the Museum of Comparative Zoology’s website. It has been confirmed that Muona erred by synonymizing N. pavidus with N. teres before transferring both N. punctatus and N. teres to Dromaeolus Kiesenwetter. A correction has been made by transferring N. pavidus …

Three New Species Of Lepidocyrtus Bourlet (Collembola: Entomobryidae) From Florida, Usa, And Descriptive Notes On Lepidocyrtus Floridensis Snider, Felipe N. Soto-Adames, Emily Jenks, Kathryn M. Daly

Insecta Mundi

Abstract

In North America, the genus Lepidocyrtus Bourlet (Collembola: Entomobryidae) is represented by 18 species, but only three (L. floridensis Snider, L. millsi Snider, and L. pallidus Reuter) have been reported from Florida. We investigated species diversity in leaf litter samples from counties in the north-central and southern part of the state, as the reportedly low species diversity in Florida may be due to under-sampling. As a result, in this contribution we describe three species of Lepidocyrtus new to science: L. bobwoodruffi Soto-Adames, Jenks and Daly, new species, L. brambilae Soto-Adames, Jenks and …

However, coupled with geographic site locations, they reveal important habitat information. The various site locations are specifically defined as part of the Eastern Temperate Forests Level I Ecoregion of North America, numerous Level III Ecoregions of the Continental United States, several United States Forest Type Groups, and natural habitat designation of mesic open woodland.

A Taxonomic Note On Lecanium Vaccinii Macrocarpum Nomen Dubium Status, Rhys J. L. Campo, Barbara D. Denno, Douglass R. Miller

Insecta Mundi

Lecanium vaccinii macrocarpum Goethe, 1884 (Hemiptera: Coccidae) is a subspecies of which the original description is inconsistent with its current taxonomic placement, and its recorded synonymy with other species is questionable. The original type material is likely lost or destroyed. For these reasons, L. vaccinii macrocarpum is proposed to be treated as nomen dubium.
