Hybridization Between The Rare Gray-Headed Chickadee And The Abundant Boreal Chickadee In The Midst Of Shifting Climate, Matthew R. Armstrong

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

As species respond to changing climate, distributions and abundances may shift and alter species interactions. Hybridization, a relatively widespread phenomenon becoming more common with climate change, can have beneficial and detrimental effects on population growth rates and genetic integrity. Beneficial effects due to the introduction of advantageous alleles and increased genetic diversity may result from hybridization. Species may also accrue fitness costs associated with changing climates if mismatches occur between environmental variables and phenotypes. The gray-headed chickadee, Poecile cinctus lathami, is an extremely rare songbird that has experienced marked declines in recent decades within its restricted distribution in Alaska …

Asynchronous Movement Patterns Between Breeding And Stopover Locations In A Long-Distance Migratory Songbird, Theodore J. Zenzal Jr., Andrea Contina, Hannah B. Vander Zanden, Leanne K. Kuwahara, Daniel C. Allen, Kristen M. Covino

School of Integrative Biological & Chemical Sciences Faculty Publications

The species-specific migratory patterns and strategies of many songbirds remain unknown or understudied, as research in animal ecology is biased toward the breeding period, with the fewest studies on the migratory period across taxa. Identifying large-scale spatiotemporal migratory patterns is challenging, as individuals within a species may vary in their migratory behavior and strategies. The Yellow Warbler (Setophaga petechia) is a Nearctic-Neotropical migrant that is relatively well studied during the breeding season, but its species-wide migratory patterns remain understudied. Our aim in studying Yellow Warbler movement ecology was to characterize temporal migration patterns during fall migration. We sought …

Spring Field Report, March–May 2024, W. Ross Silcock

Nebraska Bird Review

A major concern this spring was the widely lamented shortfall in numbers of migrant warblers and the shortened duration of the migration, with most sightings relatively early. Numbers of migrant warblers east of the 100th meridian were investigated by Joel Jorgensen and Stephen Brenner and the scarcity was indeed found to be supported by eBird data; see the “News and Updates” section in Birds of Nebraska-Online (BONO). At Oliver Reservoir in the Panhandle, however, Steven Mlodinow found that migration was at least normal for a range of common migrants, with some migrants above the levels of the last four years. …

The Early Years Of The Nebraska Ornithologists’ Union: People And Publications, Daniel W. Leger

Nebraska Bird Review

Nebraska once boasted that it had the greatest avian biodiversity of any state. Today, such a claim seems preposterous, but when it was made, back in 1899, it was serious. The antecedents of that claim underlie the objective of this article, namely to describe the early history of the Nebraska Ornithologists’ Union (NOU), its founding members, and its publications, one of which, the Nebraska Bird Review, you are reading today.

. . .

To say that many changes have occurred in ornithology and birding since the NOU started in 1899 would be a severe understatement. Most of these changes have …

Reproductive Success And Post-Fledging Ecology Of The American Robin (Turdus Migratorius) In Suburban Areas Of The Arkansas River Valley, Brandon Maiersperger

ATU Theses and Dissertations 2021 - Present

Study of the nesting and post-fledging periods is necessary to properly evaluate avian reproductive success. Birds breeding in suburban areas are threatened by a high abundance of predators and limited habitat availability. American Robins (Turdus migratorius) are common birds in suburban areas across North America, but their breeding ecology is understudied. The goals of my study were to: assess robin nest survival and its relationships with nest characteristics, evaluate fledgling survival, movement, and behavior, and determine the fledging sex ratio and sex-based plumage characteristics of fledglings. I found that robin daily nest survival (0.920) was lower than previous …

Crossing The Ocean: The Importance Of Gene Flow In Island Evolution, Ethan F. Gyllenhaal

Biology ETDs

Islands have long been a critical arena for the development of ecological and evolutionary theory, particular due to persistent open-water gaps between them. In this dissertation I demonstrates how these caps are permeable, which can be leveraged to understand evolution on islands and more broadly. The first chapter develops this connection between ongoing, overwater gene flow and island biogeographic theory, and tests it on an archipelago species. The second take a three-pronged approach in demonstrating how over-water gene flow can bias phylogenetic inference, and how many phylogeographic metrics in islands are likely shaped by long-term gene flow. The final two …

Eviction-Driven Infanticide And Sexually Selected Adoption And Infanticide In A Neotropical Parrot, Steven R. Beissinger, Karl S. Berg

School of Integrative Biological & Chemical Sciences Faculty Publications

Significance

Infanticide and adoption are puzzling forms of sexual conflict and cooperation, respectively. However, both may be explained by sexual selection, where an individual later reproduces with the parent whose offspring it killed or adopted. While sexually selected infanticide is well known, evidence for sexually selected adoption is anecdotal. Our long-term study of a parrotlet in Venezuela found infanticide attacks were mostly enacted by nonbreeding pairs attempting to evict parents from their nests to usurp the cavity. Infanticide attacks occurred less often at nests where a parent died, and adoption by stepparents was as common as infanticide. Becoming an adoptive …

Microplastic Quantification On The Effect Of Endoparasite Communities In Florida Seabirds, Sarah N. Prieto

All HCAS Student Capstones, Theses, and Dissertations

Microplastics are being studied in a variety of different projects to better understand their impact and threat to wildlife species. Although there is an understanding that microplastics are affecting our wildlife, there are still questions about how coastal seabirds come to ingest them and how the ingestion is altering critical biological processes, such as that for endoparasite communities. This project aims to determine a better understanding of two main objectives: assessment of the presence of secondary ingestion of microplastics in coastal seabirds due to the fish species they prey on and relationship between microplastics and endoparasite communities' structure and state …

Evaluation Of Interior Least Tern (Sterna Antillarum Anthalassos) Colony Success Rate And Distance Upstream On The Arkansas River, Coley Turner, Nathan Mansor, Shelby Hunter

ATU Scholars Symposium

The previously endangered Interior Least Terns (or LETEs) are currently being monitored to ensure their populations are increasing. The purpose of this study was to provide current data to inform management decisions that must be made during their migration season. Sandbars where LETEs colonized were assigned a number corresponding to river mile. Fledglings per Breeding pair Rate (FBR) was calculated by dividing peak fledgling count by half of the adult count. A total of 798 adult LETEs and 228 fledglings were observed on sandbars. A colony was considered ‘failed’ if it had an FBR of 0, and ‘successful’ for anything …

Changes In Animal Vocalizations In Response To A Total Solar Eclipse, Colton W. Morris

ATU Scholars Symposium

My proposed research project will study the changes in animal vocalizations in response to the total solar eclipse that will take place in Russellville, Arkansas, on April 8, 2024. I will use audio recordings before, during, and after the eclipse to quantify changes in animal vocalizations. Most recordings will be in the range of normal hearing, and will primarily detect birds, frogs, and insects. Additionally, I will deploy one ultrasonic recorder capable of detecting bats. From these recordings I will be able to quantify overall and species-specific call rates. Audio recordings will be paired with continuous measurements of light intensity …

Socioecological Assessment Of Birds In Ngezi-Vumawimbi Nature Forest Reserve, Eli Taub

Independent Study Project (ISP) Collection

Effective management of natural resources requires consideration of the environment through both a physical and a sociological lens. In this study, the birds in Ngezi-Vumawimbi Nature Forest Reserve were examined through both a biological mist-net survey and a socioecological series of interviews with people living in the surrounding villages. The mist-net survey compared the understory species in undisturbed and disturbed area of the forest, as well as analyzing birds caught for biologically meaningful information on subspecies and sexual dimorphism. While the mist-net survey was largely unsuccessful, highlighting the need for alternative bird capture methods in Ngezi, it found a decrease …

Avian Diversity And Abundance Among Agricultural Land, Forested Land, And Their Ecotone In Guadalupe, Cerro Punta, Chiriquí Province, Republic Of Panamá., Stella Rae Kinard

Independent Study Project (ISP) Collection

As the human population increases, finding the balance between modifying land use for resources and protecting areas to preserve species that are threatened by anthropogenic disturbance is an ever growing problem. Guadalupe is a town in the Western Highlands of Panamá that struggles in this balance as its primary income source is agriculture, but it is located on the border of two protected areas, Parque Nacional La Amistad and Parque Nacional Volcán Barú. By understanding the unique ways in which avifauna utilize distinct vegetative landscapes, recommendations can be made for management styles of farms in Guadalupe to implement practices that …

Influences Of Sex, Morph, And Weather On Roosting Distributions In Overwintering White-Throated Sparrows (_Zonotrichia Albicollis_), Rebecca Stephens

Honors Theses

Habitat choice influences survival by affecting access to resources, shelter from predators, mating opportunities, and numerous other costs and benefits. As such, habitat conservation is crucial, especially for migratory songbirds which are declining primarily due to habitat destruction. White-throated Sparrows (Zonotrichia albicollis) are a well-studied migratory songbird, but little is known about their roosting behaviors or how those behaviors are affected by sex, color morph, or weather. To determine this, we tracked White-throated Sparrows to their roosts, determined core home ranges, and analyzed the average distances of roost sites to the home range centroids according to these factors. …

Demographic Consequences Of Off-River Nesting For Piping Plover (Charadrius Melodus) And Interior Least Tern (Sternula Antillarum Athalassos) In The Lower Platte River System, Nebraska, Elsa M. Forsberg

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

Piping plovers (Charadrius melodus; hereafter, plovers) and interior least terns (Sternula antillarum athalassos; hereafter, terns) are two avian species that nest along the Lower Platte River system (LPRS) in Nebraska. In the LPRS, river sandbars provide natural nesting habitat, but off-river sites provide substantial nesting habitat especially when sandbar habitat is scarce. Although presumed to be important for the persistence of plovers and terns, off-river habitat is not self-sustaining and predicted to decline. Understanding the vital rates of plovers and terns in the LPRS will inform the role of off- river sites in the future conservation …
