The Endangered California Condor (Gymnogyps Californianus) Population Is Exposed To Local Haemosporidian Parasites, M. Andreína Pacheco, Chris N. Parish, Timothy J. Hauck, Roberto F. Aguilar, Ananias A. Escalante
Harold W. Manter Laboratory of Parasitology: Library Materials
The endangered California Condor (Gymnogyps californianus) is the largest New World Vulture in North America. Despite recovery program success in saving the species from extinction, condors remain compromised by lead poisoning and limited genetic diversity. The latter makes this species especially vulnerable to infectious diseases. Thus, taking advantage of the program of blood lead testing in Arizona, condor blood samples from 2008 to 2018 were screened for haemosporidian parasites using a nested polymerase chain reaction (PCR) protocol that targets the parasite mitochondrial cytochrome b gene. Plasmodium homopolare (Family Plasmodiidae, Order Haemosporida, Phylum Apicomplexa), was detected in condors captured …

Summer Field Report, June-July 2020, W. Ross Silcock
Nebraska Bird Review
Overall, this was a fairly routine summer although birders in Nebraska know that “routine” still holds promise of a few happenings out of the ordinary. The summer season primarily examines new breeding records, range expansions, and changes in numbers, up or down. Mississippi Kites were conspicuous, a pair providing Scottsbluff’s first breeding record, but a repeating pair in Lincoln, Lancaster lost its nest in a windstorm. The first nesting record for Violet-Green Swallow for Sheridan, 7th nesting for White-winged Dove, and 9th for Short-eared Owl were all encouraging, as was an apparent family group of Northern Saw-whet Owls in Sioux. …

Robert Wolcott And The Art Of Nest Records, Thomas E. Labedz
Nebraska Bird Review
The autumn of 1894 was fortuitous for Nebraska ornithology because it is when Robert Henry Wolcott accepted an assistantship at the University of Nebraska, moving to Lincoln from the University of Michigan (Swenk 1935). Wolcott, from that point onward, made significant contributions to our knowledge of Nebraska birds (Bruner et al. 1903, Wolcott 1909, 1919), was a founding member of the Nebraska Ornithologists’ Union (NOU), and was editor for the first three Proceedings of the NOU from 1899-1902. His work expanded beyond local focus and he eventually authored a text on animal biology (Wolcott 1933). The topic of this paper, …

Long‐Distance Natal Dispersal Is Relatively Frequent And Correlated With Environmental Factors In A Widespread Raptor, Hanna M. Mccaslin, T. Trevor Caughlin, Julie A. Heath
Biology Faculty Publications and Presentations
- Dispersal is a critical process influencing population dynamics and responses to global change. Long‐distance dispersal (LDD) can be especially important for gene flow and adaptability, although little is known about the factors influencing LDD because studying large‐scale movements is challenging and LDD tends to be observed less frequently than shorter‐distance dispersal (SDD).
- We sought to understand patterns of natal dispersal at a large scale, specifically aiming to understand the relative frequency of LDD compared to SDD and correlates of dispersal distances.
- We used bird banding and encounter data for American kestrels (Falco sparverius) to investigate the effects of …
Sensory Stressors Impact Species Responses Across Local And Continental Scales,

Sensory Stressors Impact Species Responses Across Local And Continental Scales, Ashley A. Wilson
Master's Theses
Pervasive growth in industrialization and advances in technology now exposes much of the world to anthropogenic night light and noise (ANLN), which pose a global environmental challenge in terrestrial environments. An estimated one-tenth of the planet’s land area experiences artificial light at night — and that rises to 23% if skyglow is included. Moreover, anthropogenic noise is associated with urban development and transportation networks, as the ecological impact of roads alone is estimated to affect one-fifth of the total land cover of the United States and is increasing in space and intensity. Existing research involving impacts of light or noise …

Analyzing The Longevity Of Sperm Within The Female Japanese Quail By Assessing Sperm Penetration Of The Perivitelline Layer Under Optimal And Suboptimal Conditions., Garret G. Ashabranner, Joey L. Bray
Electronic Theses and Dissertations
After mating, birds have the ability to store semen within the female reproductive tract. The sperm storage tubules will store and subsequently release semen to travel up the oviduct. Sperm cells that make the trek up the oviduct have a chance to fertilize the ovum. These sperm cells will bind to the perivitelline layer of the ovum and hydrolyze a hole in the perivitelline layer, where it has the possibility to fertilize the female sex cell. Analyzing the number of penetration points on the perivitelline layer is an effective way to analyze reproductive efficiency. Many environmental factor has its effect …

A Test Of The Sexually Selected Egg Color Hypothesis In Eastern Bluebirds (Sialia Sialis), Annabelle Mckie-Voerste
Student Theses and Dissertations
The broad array of colors represented in avian eggshells has promoted extensive investigations into its evolutionary significance. Although many hypotheses exist that explain conspicuous egg colors, including egg recognition against brood parasitism, protection from UV rays, and thermoregulation, they fail to adequately explain the adaptive function of vivid blue eggs. The Sexually Selected Egg Color Hypothesis (SSECH) states that blue-green eggshell coloration is a post-mating, sexually selected signal that conveys female quality, and male birds that observe more pigmented eggs would increase their care accordingly, resulting in higher quality chicks. Using a population of eastern bluebirds (Sialia sialis) in northeast …

Exploring The Effects Of Geographic And Landscape Variation On Avian Communities And Species, Joseph Youtz
Student Theses and Dissertations
Ongoing and intensive anthropogenic change has modified the globe across multiple scales, yet the influence of these modifications on wildlife communities and individuals remain region and species specific. Here I explored the influence of a biogeographical pattern as it relates to climate and geography, and the effects of historic habitat loss and fragmentation on a diverse avian community. I first explored the adherence to Bergmann’s rule within a migratory songbird, the Prothonotary Warbler (Protonotaria citrea), across all life stages and time. The pattern was present from the young nestling stage through adulthood, although contemporary eggs followed a reverse relationship with …

Cerulean Warbler Habitat Selection, Breeding Biology, Survival, And Space Use In The Ozark Region, Jacob Louis Wessels
Student Theses and Dissertations
For many declining migratory birds, gaps in information on their ecology can impede conservation efforts. Cerulean Warblers (Setophaga cerulea; hereinafter ceruleans) are one such rapidly declining species and have regional ecological variation, so more comprehensive information may benefit their effective conservation. We studied ceruleans in the Ozark region of Arkansas to increase the scientific knowledge of this species in an understudied region that likely supports a ‘natural population’ of ceruleans. We assessed habitat selection, breeding biology, survival, and space use of ceruleans. Consistent with other regions, ceruleans at our study sites selected areas with large trees across spatial scales. Males …

Effects Of Management Efforts On Fledging Success Of Endangered Interior Least Terns (Sternula Antillarum Athalassos) On The Mcclellan-Kerr Arkansas River Navigation System In Arkansas, Trevor N. Jensen
Theses and Dissertations from 2020
The Interior Least Tern (Sternula antillarum athalassos) is an endangered shorebird that primarily nests in colonies on barren riverine sandbars on many major river systems throughout the central United States. Water resource development projects such as damming and channelization have altered the natural flow regimes of these systems leading to a decrease in sandbar quality and quantity, and as a result this species is dependent on management to ensure their recovery. Managers within Arkansas have been applying a variety of management approaches to improve sandbar nesting habitat and success of this population intermittently since 2002, with increased intensity since 2015. …

Prevalence Of Anticoagulant Rodenticides In Ferruginous Hawk Nestlings And Evaluation Of A Novel Method To Rapidly Assess Exposure, Ariana Joyce Dickson
Boise State University Theses and Dissertations
Anticoagulant rodenticides (ARs) are compounds commonly used to control rodent pests by inhibiting an enzyme critical for synthesis of clotting factors in their blood. Secondary and tertiary poisoning of non-target species frequently occur, especially of predators that consume rodents, including many species of raptors. Although raptor exposure to ARs has been documented on at least three continents, patterns, pathways and the sub-lethal effects of exposure are not well studied. This has created a substantial need to monitor the effects of ARs in free-living populations. I evaluated the prevalence of secondary, non-target exposure to anticoagulant rodenticides experienced by a predatory raptor, …

Movements Of White-Headed And White-Backed Vultures, Teague K. Scott
Boise State University Theses and Dissertations
Vultures are the only obligate vertebrate scavengers, and as such provide crucial services as keystone species and support the health and function of ecosystems in which they live. African vultures are a diverse group, with nine species found throughout Sub-Saharan Africa, many with overlapping distributions. Unfortunately, African vultures are faced with numerous threats throughout their range that have led to significant population declines, some greater than 90%, in only three generations. Four of these species are currently listed as critically endangered, and three as endangered.
Despite the significant perils faced by African vultures, there are still significant knowledge gaps and, …

Snowy Plover Activity In The Central Platte River Valley In May 2019, Bethany L. Ostrom, Andrew J. Caven, Jenna M. Malzahn, Alyx Vogel
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
During five of eight site visits between 14 and 27 May 2019 we detected up to four Snowy Plovers (Charadrius nivosus nivosus) in the Central Platte River Valley (CPRV) near Mormon Island, Hall County, Nebraska, and recorded their behavior using an instantaneous scan sampling approach. We recorded loafing (47%), foraging (43%), mating (4%), flying (4%), and external threat (1%) related behavior. Most notably, we documented a copulation event on 23 May. During the 10-day span from 14 to 23 May when Snowy Plovers were detected, river stage and discharge were near median levels, but from 23 to 27 …
