Building Heat-Resilient Caribbean Reefs: Integrating Thermal Thresholds And Coral Colonies Selection In Restoration, Macarena Blanco Pimentel, Johanna Calle-Triviño, Daniel J. Barshis, Sancia E. T. Van Der Meij, Megan K. Morikawa

Biological Sciences Faculty Publications

Caribbean reefs face increasingly frequent and intense bleaching events, adding to the numerous other threats impacting these ecosystems. Addressing these challenges requires global action to reduce climate drivers, along with local efforts like reef restoration. Active restoration using thermotolerant coral colonies offers a potential strategy to alleviate these impacts; however, gaps remain in identifying context-specific temperature thresholds to guide colony selection and standardize thermotolerance assessment methods. This study addressed these gaps in two phases. First, by determining practical thresholds to differentiate species responses to heat stress; and second, by developing a framework to identify and prioritize resilient colonies for restoration. …

First Reference Genomes For Two Mesophotic Reef Building Coral Species: Leptoseris Cf. Scabra And Montipora Cf. Grisea, Veronica Z. Radice, Johanna C. Gijsbers, Silvia Vimercati, Daniel J. Barshis

Biological Sciences Faculty Publications

Coral mortality is occurring worldwide at an alarming rate. Despite the immense and underestimated biodiversity of reef-building corals, very few genomes are available. Further, almost all genomic resources originate from shallow water corals even though photosynthetic, symbiotic corals occur at mesophotic depths deeper than 30 m and even >100 m. We present annotated, de novo genomes for two mesophotic, scleractinian (reef-building) corals Montipora cf. grisea and Leptoseris cf. scabra from American Sāmoa, the latter being the first genome for the widespread genus Leptoseris. We used PacBio continuous long reads and Omni-C data to assemble chromosome-level reference genomes. For Montipora …

Validating A Novel Capability Of Assessing Pathways Of Animal Water Gain And Loss, Zachary T. Steele, Karen Caceres, Zachary A. David, Lisa M. Shollenberger, Alexander R. Gerson, Seth D. Newsome, John P. Whiteman

Biological Sciences Faculty Publications

Understanding variations in the routes by which wild animals gain and lose water is challenging, and common methods require longitudinal sampling, which can be prohibitive. However, a new approach uses Δ′¹⁷O_BW (Δ′¹⁷O of animal body water), calculated from measurements of δ′¹⁷O and δ′¹⁸O in a single sample, as a natural tracer of water flux. Δ′¹⁷O_BW is promising, but its relationship to organismal variables such as metabolic rate and water intake have not been validated. Here, we continuously measured oxygen influxes and effluxes of captive deer mice (Peromyscus maniculatus), and manipulated their water intake and metabolic rate. We used …

The feeding ecology of wildlife populations has important implications for individual health, population productivity and distribution patterns. For ursids (bears), food resources and feeding behaviour primarily affect population dynamics via effects on cub production and survival. Much of what is known about the feeding ecology of bears is based on analyses of tissues collected from capture-based research efforts, harvested animals or non-invasive approaches. However, inference about diet from hair has been limited by a lack of quantitative data on the timing of the moult and hair growth rates. We conducted a study to develop and test two methods of quantifying …

Future-Oriented Coastal Protection: The Utility Of Living Shorelines Under Changing Climatic Conditions, Gabriella R. Dipetto, Donna Marie Bilkovic, Taylor M. Sloey, Erik S. Yando, Erik L. Walters

Biological Sciences Faculty Publications

An accumulation of novel nature-based shoreline management techniques have developed over the past two decades out of the continued need to protect waterfront land combined with an awareness of the relationship between healthy coastal ecosystems and human societies. Shoreline protection strategies such as living shorelines incorporate these nature-based approaches to simultaneously enhance ecosystem functioning while providing shoreline stabilization benefits. The continued role of these approaches into the future, however, will be challenged by a rapidly changing coastal environment. While living shorelines have received global attention and integration into climate policy and governance frameworks, the ability of shoreline systems to withstand …

Oxidation Camouflages Terrestrial Organic Matter To Appear Marine-Like, Aleksandar I. Goranov, Susan J. Carter, Ann Pearson, Patrick G. Hatcher

Chemistry & Biochemistry Faculty Publications

The export of terrestrial organic matter (TOM) to the ocean has been traditionally viewed to be minimal or only of significance in near-coastal continental margins. The broadly accepted explanation for the widespread loss of terrestrial lignin biomarkers and apparent disappearance of the <-25‰ stable carbon isotopic signature (δ¹³C) of TOM is that TOM is almost fully degraded before reaching the open ocean. Oceanic carbon (δ¹³C value ≥ -22‰) is therefore thought to be derived primarily from algae. However, an alternative explanation for the different molecular and δ¹³C signatures in terrestrial and marine environments may be that oxidative processing transforms TOM to appear marine-like. To test this hypothesis, we subjected eight TOM samples to a strong oxidation gradient. At carbon losses typical of TOM degradation during transport and sedimentation (above 60%), the differentiators of provenance disappeared, leaving a residue that was marine-like both chemically (aliphatic- and nitrogen-rich) and isotopically (δ¹³C enrichment of 4 to 9‰). This challenges the validity of conventional two-endmember mixing models, suggesting that a much larger fraction than previously estimated of the organic matter found in the ocean may originate from terrestrial sources, impacting global models of carbon cycling and sequestration.

Amphiphilic Tripodal Metalloligands: Synthesis, Coordination Chemistry And Preliminary Catalysis, Austin W. Medley, Paul D. Miller, Craig A. Bayse, Robert D. Pike, Trandon A. Bender

Chemistry & Biochemistry Faculty Publications

Triscatecholate binding has been widely studied in the context of biological systems, supramolecular chemistry, and weak aggregate interactions. However, the utilization of the triscatecholate binding motif for the preparation of metalloligands remains unexplored. Herein, we report the synthesis, structural characterization, and functional studies of a triscatecholate ligand with an appended pyridyl residue as a candidate for such applications. Our findings reveal that the selective formation of cis-triscatecholate-based metalloligands is influenced by electronic effects on the catecholate anions, enabling the targeted synthesis of Al(III), Ga(III), and In(III) triscatecholate metalloligands capable of binding Zn(II) and Ru(II) at the appended pyridyl moiety for …

[Review Of The Book America's Black Capital: How African Americans Remade Atlanta In The Shadow Of The Confederacy, By J. O. G. Ogbar]., Marvin T. Chiles

History Faculty Publications

[Introduction] Since the mid-twentieth century, Atlanta has occupied a special place in American culture. From entertainment to industry to politics, Atlanta is one of the few places in America where what happens locally matters nationally. As a results, Atlanta has occupied an outsized space in African American, civil rights, and southern historical literature, leading to its own subgenre that can be called Atlanta studies. The historiography, including notable volumes such as Ronald H. Bayor's Race and the Shaping of Twentieth-Century Atlanta (Chapel Hill, 1996), Kevin M. Krusc's White Flight: Atlanta and the Making of Modern Conservatism (Princeton, 2005), Tomiko Brown-Nagin's …

[Review Of The Book Closed Seasons: The Transformation Of Hunting In The Modern South, By J. Brock]., Tracy L. Barnett

History Faculty Publications

[Introduction] The hunt has long occupied a central place in southern lore and literature. For generations, fathers and grandfathers initiated their sons into its rituals, teaching them to steady a rifle, bait a hook, and cast a line. In the twentieth century, William Faulkner and other writers elevated this long-held tradition into mythology, evoking both the exhilaration of the chase and the gothic romance of Mississippi’s pine forests. And, today, around 5.3 million southerners (of all races and genders) hold hunting licenses and organize their calendars around the season’s rhythms and associated social gatherings. Focusing on the Deep South states …

A Forgotten Piece Of History: The Story Of The First Municipal Council Of Colombo, Sri Lanka, Chandra Richard De Silva

Constitutionalism And Peacemaking: Comparative Perspectives, Ruti G. Teitel

Articles & Chapters

This chapter addresses the relationship of constitutionalism in periods of political transition. Comparative analysis of a number of case studies points to a dynamic relationship whereby constitutional change can lead political change; whereas, in others, political transformation precedes constitutional change and involves institutions of constitutional interpretation. Constitutional courts have played important interpretive roles in this project, often supporting transitional projects of peacemaking and transformative politics with enduring constitutional values. Moreover, these constitutional moments are tied to distinctive understandings of peace and transitional justice.

The Effect Of Need For Closure, Gender Essentialism, And Contact On Transphobia, Jacob E. Vargas

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Using a motivated social cognition framework, this study explores whether there is an indirect effect of need for closure on transphobia via gender essentialism and whether this relationship is moderated by transgender contact. Data were collected from an undergraduate sample of 405 cisgender participants (n_men = 159, n_women = 246). A simple mediation and a moderated mediation were used to examine the hypothesized relationships, controlling for participant gender. Results reinforced the positive correlation between gender essentialism and transphobia and the negative correlation between transgender contact and transphobia. However, the mediation and moderation hypotheses were not supported. Need …

Experimental Evaluation Of Corrosion Of Strands And Wires To Estimate Corrosion Rate In Grout And Concrete, Dipendra Shrestha

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

Premature failure of prestressed and post-tensioned concrete structures is frequently caused by undetected corrosion of prestressing steel. Although extensive research has addressed corrosion rates in conventionally reinforced concrete, the interpretation of non-destructive parameters, such as half-cell potential (HCP) and concrete/grout resistivity, for estimating corrosion rates in prestressing steel are not adequately investigated.

This research experimentally evaluates chloride-induced corrosion of prestressing steels to establish material-specific relationships between in-situ measurable parameters and corrosion rate. Thirty-six macrocell specimens incorporating plain wires, indented wires, and seven-wire strands in structural concrete and commercial post-tensioning grout- half with pre-formed surface cracks, were subjected to accelerated cyclic …

Examining Trauma And Substance Use Co-Morbidity In African Americans, Breanne Maray Sande Russell

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

Childhood maltreatment (CM) is a profound public health crisis that significantly elevates the risk for substance use disorders (SUDs), including alcohol and opioid misuse. Adolescents exposed to CM are especially vulnerable, often turning to substances as maladaptive coping mechanisms during critical developmental periods. African American youth bear this disproportionate burden, yet research addressing their unique experiences remains strikingly limited. Furthermore, while the co-occurrence of trauma-related disorders and substance use is well documented, racial and ethnic minority groups continue to be underrepresented in this literature. Emotion regulation difficulties are increasingly recognized as a mechanism linking PTSD symptoms with substance use, yet …

Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson

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

This dissertation investigates how echo chambers emerge on social media by shifting the lens from aggregate patterns of information exposure to moment-by-moment, individual level interaction decisions between peers. I theorize that selective exposure online is not only about what content people consume or avoid, but also about selective social exposure—accepting, rejecting, or sharing with the sources of that content—guided by sociopolitical identity, ideological distance (ID), and discrete emotions. To test this, I employ two survey experiments using real tweets varying in ideological extremity and measure user’s likelihood to Block, Follow, Retweet, or reply, alongside self-reported emotional reactions and ID between …

Robust Quantification Of Cortical Hemodynamic Response To Tactile Stimulation: A Comprehensive Fnirs Methodology To Mitigate Physiological Confounds, Mohsen Hozan

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

This dissertation establishes a quantitative framework for studying somatosensory processing using functional Near-Infrared Spectroscopy (fNIRS), with a focus on applications in neurorehabilitation. The central aim is to investigate how the brain's hemodynamic response is modulated by the velocity of patterned tactile stimulation. While fNIRS is a promising neuroimaging tool, its data quality is often compromised by physiological noise and motion artifacts, challenging the reliability of its findings and hindering the development of effective, quantifiable neurotherapeutics.

Two preliminary investigations informed the final experimental design. The first pilot study confirmed that pneumotactile stimulation of the hand, during both passive (somatosensory) and active …

Metamorphosis And Fairy Tale Tropes In Christa Wolf’S Patterns Of Childhood, B. E. Lara

Master's Theses and Doctoral Dissertations

This study is a sociohistorical analysis of East German writer Christa Wolf’s use of fairy tale tropes in her novel Patterns of Childhood, first published in German in 1976 in East Germany as Kindheitsmuster. Wolf uses fairy tale tropes to explore themes that she could not write about openly under East German censorship, which prohibited East German authors from exposing their culpability for prior acts committed under the Nazi Regime. Furthermore, Wolf introduces metamorphosis to explore the intrinsic evil and subsequent guilt of her child protagonist, and she uses the child’s capacity for evil to illustrate the German people’s similar …
