Acquisition Of New Function Through Gene Duplication In The Metallocarboxypeptidase Family, Daniel Fajardo, Ritchie Saint Jean, Peter J. Lyons

Faculty Publications

Gene duplication is a key frst step in the process of expanding the functionality of a multigene family. In order to better understand the process of gene duplication and its role in the formation of new enzymes, we investigated recent duplication events in the M14 family of proteolytic enzymes. Within vertebrates, four of 23 M14 genes were frequently found in duplicate form. While AEBP1, CPXM1, and CPZ genes were duplicated once through a large-scale, likely whole-genome duplication event, the CPO gene underwent many duplication events within fsh and Xenopus lineages. Bioinformatic analyses of enzyme specifcity and conservation suggested a greater …

Potential Repercussions Of Offshore Wind Energy Development In The Northeast United States For The Atlantic Surfclam Survey And Population Assessment, Sarah Borsetti, Daphne M. Munroe, Andrew M. Scheld, Eric N. Powell, John M. Klinck, Eileen E. Hofmann

Faculty Publications

The Atlantic surfclam Spisula solidissima fishery, which spans the U.S. Northeast continental shelf, is among the most exposed to offshore wind energy development impacts because of the overlap of fishing grounds with wind energy lease areas, the hydraulic dredges used by the fishing vessels, and the location of vessel home ports relative to the fishing grounds. The Atlantic surfclam federal assessment survey is conducted using a commercial fishing vessel in locations that overlap with the offshore wind energy development. Once wind energy turbines, cables, and scour protection are installed, survey operations within wind energy lease areas may be curtailed or …

Seeing In The Dark: A Review Of The Use Of Side-Scan Sonar To Detect And Study Manatees, With An Emphasis On Latin America, Daniel Gonzalez-Socoloske, León David Olivera-Gómez

Faculty Publications

Manatees are aquatic mammals that live in a variety of environments. Many of those shallow water environments have murky water, making detection using traditional visual surveys very challenging. Side-scan sonar was first proposed as a tool to detect and study manatees in these complicated habitats in 2005. Here, we summarize the use of this tool from 2005 to 2022 by searching the available literature. Our literature search revealed that this tool is being widely used in more than 20 locations and over 15 countries. All three manatee species are being studied with side-scan sonar. It is most useful in murky …

An Examination Of Depression, Anxiety, And Self-Esteem In Collegiate Student-Athletes, Samantha R. Weber, Zachary K. Winkelmann, Eva V. Monsma, Shawn M. Arent, Toni M. Torres-Mcgehee

Faculty Publications

Mental health research exists for student-athletes in the areas of depression, anxiety, and self-esteem prevalence. However, updated prevalence rates and assessment of risks across sports, academic status, and genders are needed. Filling the gaps in research assists in the creation of patient-centered mental health screening and interventions designed for student-athletes. Therefore, the purpose is to examine the prevalence of depression, anxiety, and self-esteem in collegiate student-athletes and differences between sex, academic status, and sport type, and identify associations for risks. Using a cross-sectional design, collegiate student-athletes were surveyed to assess for risks of depression, anxiety, and self-esteem. With the use …

Conservation Easements: A Tool For Preserving Wildlife Habitat On Private Lands, Robin M. Rotman, Sarah A. Brown, Michael A. Powell, Sonja A. Wilhelm Stanis

Faculty Publications

Conservation easements are an essential tool for conserving private lands, and they have great potential for enhancing wildlife habitat and biodiversity. Private land conservation in the United States is likely to increase in the coming years, in light of Executive Order No. 14,008, issued by President Joseph Biden on January 27, 2021, which set a goal of conserving at least 30% of U.S. lands and waters by 2030 (Executive Office of the President 2021). There is, therefore, a need to evaluate the effect of conservation easements on wildlife habitat and biodiversity and to make recommendations for further enhancing the effectiveness …

Survival In Common Snapping Turtles, Chelydra Serpentina (Testudines: Chelydridae), In Western Nebraska, John B. Iverson, Geoffrey R. Smith

Faculty Publications

Annual estimates of survival for Common Snapping Turtles (Chelydra serpentina) in western Nebraska USA were generated from mark-recapture data from nesting females encountered in 2005–2017. Our population models suggested no annual variation in either adult annual survival (0.947 ± 0.017 SE) or annual capture probability (0.294 ± 0.027 SE). However, there was a tendency toward higher survival in larger females. High annual survival (e.g. > 90%) characterises populations of Chelydra from Ontario to Texas.

Dataset For Effects Of Single-Session Practice Structure On Motor Skill Acquisition And Alpha And Beta Eeg Oscillations, Audrey Porter, Ronald V. Croce, Wayne Smith

Faculty Publications

Although it is known that practicing a motor skill updates the associated internal model, it is still unclear as to how cortical oscillations linked with the motor skill change under differing practice schedules. The current study investigated α- and β-power changes associated with motor skill acquisition. Firstly, we investigated the behavioral effects of practice on motor learning and retention during repetitive (RP) and variable (VP) practice schedules on an anticipation timing task. Secondly, we investigated changes in cortical α (10-13 HZ) and β (15-30 Hz) event-related synchronization and dyssynchronization (ERS/ERD) under RP and VP during early (EP) and late …

A Tree-Ring Record Of Historical Fire Activity In A Piedmont Longleaf Pine (Pinus Palustris Mill.) Woodland In North Carolina, Usa, Monica T. Rother, Thomas W. Patterson, Paul A. Knapp, Tyler J. Mitchell, Nell Allen

Faculty Publications

CO₂ capture from industrial point source waste streams represents an important need for achieving the global goal of carbon-neutrality. Compared with conventional liquid sorbents, solid sorbents can exhibit several distinct advantages, including enhanced lifetime and reduced energy consumption for sorbent regeneration. Considering that reducing CO₂ emission is a great challenge, reaching approximately 37 billion metric tons just in 2021, ideal sorbent solutions should not only exhibit a high capture performance but also enable large scale manufacturing using low-cost precursors and simple processes. In this work, we demonstrate the use of a commodity polymer, polystyrene-block-polyisoprene-block-polystyrene …

Insectdisease: Programmatic Access To The Ecological Database Of The World’S Insect Pathogens, Tad Dallas, Colin J. Carlson, Patrick R. Stephens, Sadie J. Ryan, David W. Onstad

Faculty Publications

Curated databases of species interactions are instrumental to exploring and understanding the spatial distribution of species and their biotic interactions. In the process of conducting such projects, data development and curation efforts may give rise to a data product with utility beyond the scope of the original work, but which becomes inaccessible over time. Data describing insect host–pathogen interactions are fairly rare, and should thus be preserved and curated with appropriate metadata. Here, we introduce the insectDisease R package, a mechanism for curating, updating and distributing data from the Ecological Database of the World's Insect Pathogens, a database of insect …

Epidemic Time Series Similarity Is Related To Geographic Distance And Age Structure, Tad Dallas, Grant Foster, Robert L. Richards, Bret D. Elderd

Faculty Publications

Objective

More similar locations may have similar infectious disease dynamics. There is clear overlap in putative causes for epidemic similarity, such as geographic distance, age structure, and population size. We compare the effects of these potential drivers on epidemic similarity compared to a baseline assumption that differences in the basic reproductive number (R₀) will translate to differences in epidemic trajectories.

Methods

Using COVID-19 case counts from United States counties, we explore the importance of geographic distance, population size differences, and age structure dissimilarity on resulting epidemic similarity.

Results

We find clear effects of geographic space, age structure, …

A Molecular Chemodosimeter To Probe “Closed Shell” Ions In Kidney Cells, Rashid Mia

Faculty Publications

Two quinidine-functionalized coumarin molecular probes have been synthesized and have been found to bind metal cations (Cd2+, Co2+, Cu2+, Fe2+, Hg2+, Ni2+, and Zn2+) with high affinity in organic–aqueous media (DMSO–HEPES). The chemodosimeters coordinate with the Zn2+ ions in a two-to-one ratio (molecular probe : Zn2+) with a log β of 10.0 M−2. Upon the addition of the closed-shell metal ions studied, a fluorescence turn-on via an excimer formation is seen at 542 nm due to the quinaldine moiety adopting a syn arrangement when coordinated to the metal Zn2+ ions. Confocal microscopy monitored free Zn2+ ions in the Human Embryonic …

Rickettsia Parkeri Infection Modulates The Sialome And Ovariome Of The Gulf Coast Tick, Amblyomma Maculatum, Melina Garcia Guizzo, Khemraj Budachetri, Abdulsalam Adegoke, Jose M.C. Ribeiro, Shahid Karim

Faculty Publications

The Gulf Coast tick, Amblyomma maculatum, is a vector of several tick-borne pathogens, including Rickettsia parkeri. The ability of R. parkeri to persist within the tick population through transovarial and transstadial transmission, without apparently harming the ticks, contributes to the pathogen’s perpetuation in the tick population. Previous studies have shown that the R. parkeri load in A. maculatum is regulated by the tick tissues’ oxidant/antioxidant balance and the non-pathogenic tick microbiome. To obtain further insights into the interaction between tick and pathogen, we performed a bulk RNA-Seq for differential transcriptomic analysis of ovaries and salivary …

Background

Excessive gestational weight gain has increased over time and is resistant to intervention, especially in women living with overweight or obesity. This study described the process evaluation methods and findings from a behavioral lifestyle intervention for African American and white women living with overweight and obesity that spanned pregnancy (≤ 16 weeks gestation) through 6 months postpartum.

Methods

The Health in Pregnancy and Postpartum (HIPP) study tested a theory-based behavioral intervention (vs. standard care) to help women (N = 219; 44% African American, 29.1 ± 4.8 years) living with overweight or obesity meet weight gain guidelines in pregnancy and …

A Latitudinal Signal In The Relationship Between Species Geographic Range Size And Climatic Niche Area, Tad Dallas, Andrew Kramer

Faculty Publications

Species with broader niches may have the opportunity to occupy larger geographic areas, assuming no limitations on dispersal and a relatively homogeneous environmental space. Here, we use data on a large set of mammal (n = 1225), bird (n = 1829) and tree (n = 341) species to examine the 1) relationship between geographic range size and climatic niche area, 2) influence of species traits on species departures from this relationship and 3) sensitivity of these relationships to how species range size and climatic niche area are estimated. We find positive geographic range size–climatic niche area relationships for all taxa, …

Direct Measurement Of Stokes–Einstein Diffusion Of Cowpea Mosaic Virus With 19 Μs-Resolved Xpcs, Kacper Switalski, Jingyu Fang, Luxi Li, Miaoqi Chu, Erik Sarnello, Pete Jemian, Tao Li, Qian Wang, Qingteng Zhang

Faculty Publications

Brownian motion of Cowpea mosaic virus (CPMV) in water was measured using small-angle X-ray photon correlation spectroscopy (SA-XPCS) at 19.2 mu s time resolution. It was found that the decorrelation time tau(Q) = 1/DQ(2) up to Q = 0.091 nm(-1). The hydrodynamic radius R-H determined from XPCS using Stokes-Einstein diffusion D = kT/(6 pi eta R-H) is 43% larger than the geometric radius R-0 determined from SAXS in the 0.007 M K3PO4 buffer solution, whereas it is 80% larger for CPMV in 0.5 M NaCl and 104% larger in 0.5 M (NH4)(2)SO4, a possible effect of aggregation as well as …

Muscular Strength And Carotid Intima-Media Thickness In Physically Fit Young Adults: The Chief Atherosclerosis Study, Gen-Min Lin, Kun-Zhe Tsai, Yun-Chen Chang, Wei-Chun Huang, Xuemei Sui M.D., M.P.H., Ph.D., Carl J. Lavie

Faculty Publications

Background: Greater muscular strength (MusS) has been found to have an inverse association with subclinical atherosclerosis in children, as well as with mortality from cardiovascular diseases (CVDs) in middle-aged and elderly individuals. However, the association of the degree of MusS with atherosclerosis may differ by sex and has not been clarified in young adults. Methods and Results: A total of 1021 Taiwanese military personnel, aged 18–40 years, participated in annual health examinations in 2018–2020. MusS was separately assessed by 2-min push-up and 2-min sit-up numbers. Subclinical atherosclerosis was measured by the left carotid bulb intima–media thickness (cIMT) using high-resolution ultrasonography. …

Pillon, Tim Moore, Daiane Hemerich, Marilyn C. Cornelis, Eugenia Mazzaferro, Siacia Broos, Tarunveer S. Ahluwalia, Traci M. Bartz, Amy R. Bentley, Lawrence F. Bielak, Mike Chong, Audrey Y. Chu, Diane Berry, Rajkumar Dorajoo, Nicole D. Dueker, Elisa Kasbohm, Bjarke Feenstra, Mary F. Feitosa, Mark A. Sarzynski Ph.D., Faha, Facsm, Et. Al.

Faculty Publications

Although physical activity and sedentary behavior are moderately heritable, little is known about the mechanisms that influence these traits. Combining data for up to 703,901 individuals from 51 studies in a multi-ancestry meta-analysis of genome-wide association studies yields 99 loci that associate with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), leisure screen time (LST) and/or sedentary behavior at work. Loci associated with LST are enriched for genes whose expression in skeletal muscle is altered by resistance training. A missense variant in ACTN3 makes the alpha-actinin-3 filaments more flexible, resulting in lower maximal force in isolated type IIA muscle …

Trade-Offs Between Risks Of Predation And Starvation In Larvae Make The Shelf Break An Optimal Spawning Location For Atlantic Bluefin Tuna, Taylor A. Shropshire, Steven L. Morey, Eric P. Chassignet, Mandy Karnauskas, Victoria J. Coles, Estrella Malca, Raúl Laiz-Carrión, Øyvind Fiksen, Patricia Reglero, Akihiro Shiroza, José M. Quintanilla Hervas, Trika Gerard, John T. Lamkin, Michael R. Stukel

Faculty Publications

Atlantic bluefin tuna (ABT) (Thunnus thynnus) travel long distances to spawn in oligotrophic regions of the Gulf of Mexico (GoM) which suggests these regions offer some unique benefit to offspring survival. To better understand how larval survival varies within the GoM a spatially explicit, Lagrangian, individual-based model was developed that simulates dispersal and mortality of ABT early life stages within realistic predator and prey fields during the spawning periods from 1993 to 2012. The model estimates that starvation is the largest cumulative source of mortality associated with an early critical period. However, elevated predation on older larvae is …

Estimating R0 From Early Exponential Growth: Parallels Between 1918 Influenza And 2020 Sars-Cov-2 Pandemics, Grant Foster, Bret D. Elderd, Robert L. Richards, Tad Dallas

Faculty Publications

The large spatial scale, geographical overlap, and similarities in transmission mode between the 1918 H1N1 influenza and 2020 SARS-CoV-2 pandemics together provide a novel opportunity to investigate relationships between transmission of two different diseases in the same location. To this end, we use initial exponential growth rates in a Bayesian hierarchical framework to estimate the basic reproductive number, R₀, of both disease outbreaks in a common set of 43 cities in the United States. By leveraging multiple epidemic time series across a large spatial area, we are able to better characterize the variation in R₀ across the …

The Marine Gastropod Conomurex Luhuanus (Strombidae) Has High-Resolution Spatial Vision And Eyes With Complex Retinas, Allison R. Irwin, Suzanne T. Williams, Daniel Isaac Speiser, Nicholas W. Roberts

Faculty Publications

All species within the conch snail family Strombidae possess large camera-type eyes that are surprisingly well-developed compared with those found in most other gastropods. Although these eyes are known to be structurally complex, very little research on their visual function has been conducted. Here, we use isoluminant expanding visual stimuli to measure the spatial resolution and contrast sensitivity of a strombid, Conomurex luhuanus. Using these stimuli, we show that this species responds to objects as small as 1.06 deg in its visual field. We also show that C. luhuanus responds to Michelson contrasts of 0.07, a low contrast sensitivity …

Faculty Publications

Before Perseverance, Jezero crater's floor was variably hypothesized to have a lacustrine, lava, volcanic airfall, or aeolian origin. SuperCam observations in the first 286 Mars days on Mars revealed a volcanic and intrusive terrain with compositional and density stratification.The dominant lithology along the traverse is basaltic, with plagioclase enrichment in stratigraphically higher locations. Stratigraphically lower, layered rocks are richer in normative pyroxene. The lowest observed unit has the highest inferred density and is olivine-rich with coarse (1.5 millimeters) euhedral, relatively unweathered grains, suggesting a cumulate origin. This is the first martian cumulate and shows similarities to martian meteorites, which also …

Drift Macroalgal Distribution In Northern Gulf Of Mexico Seagrass Meadows, Kelly M. Correia, Scott B. Alford, Benjamin A. Belgrad, Kelly M. Darnell, M. Zachary Darnell, Bradley T. Furman, Margaret O. Hall, Christian T. Hayes, Charles W. Martin, Ashley M. Mcdonald, Delbert L. Smee

Faculty Publications

Drift macroalgae, often found in clumps or mats adjacent to or within seagrass beds, can increase the value of seagrass beds as habitat for nekton via added food resources and structural complexity. But, as algal biomass increases, it can also decrease light availability, inhibit faunal movements, smother benthic communities, and contribute to hypoxia, all of which can reduce nekton abundance. We quantified the abundance and distribution of drift macroalgae within seagrass meadows dominated by turtle grass Thalassia testudinum across the northern Gulf of Mexico and compared seagrass characteristics to macroalgal biomass and distribution. Drift macroalgae were most abundant in areas …

Snapping Shrimp Have Helmets That Protect Their Brains By Dampening Shock Waves, Alexandra C.N. Kingston, Sarah A. Woodin, David S. Wethey, Daniel Isaac Speiser

Faculty Publications

Shock waves are supersonic high-amplitude pressure waves that cause barotrauma when they transfer kinetic energy to the tissues of animals.1, 2, 3, 4 Snapping shrimp (Alpheidae) produce shock waves and are exposed to them frequently, so we asked if these animals have evolved mechanisms of physical protection against them. Snapping shrimp generate shock waves by closing their snapping claws rapidly enough to form cavitation bubbles that release energy as an audible “snap” and a shock wave when they collapse.5, 6, 7, 8 We tested if snapping shrimp are protected from shock waves by a helmet-like extension of their exoskeleton termed …

Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack

Faculty Publications

Cross-modal approaches to the study of sensory perception, social recognition, cognition, and mental representation have proved fruitful in humans as well as in a variety of other species including toothed whales in revealing equivalencies that suggest that different sensory stimuli associated with objects or individuals may effectively evoke mental representations that are, respectively, object based or individual based. Building on established findings of structural equivalence in the form of spontaneous recognition of complex shapes across the modalities of echolocation and vision and behavior favoring identity echoic–visual cross-modal relationships over associative echoic–visual cross-modal relationships, examinations of transitive inference equivalencies from initially …

Optimising Predictive Models To Prioritise Viral Discovery In Zoonotic Reservoirs, Daniel J. Becker, Gregory F. Albery, Anna R. Sjodin, Timothée Poisot, Laura M. Bergner, Binqi Chen, Lily E. Cohen, Tad Dallas, Evan A. Eskew, Anna C. Fagre, Maxwell J. Farrell, Sarah Guth, Barbara A. Han, Nancy B. Simmons, Michiel Stock, Emma C. Teeling, Colin J. Carlson

Faculty Publications

Despite the global investment in One Health disease surveillance, it remains difficult and costly to identify and monitor the wildlife reservoirs of novel zoonotic viruses. Statistical models can guide sampling target prioritisation, but the predictions from any given model might be highly uncertain; moreover, systematic model validation is rare, and the drivers of model performance are consequently under-documented. Here, we use the bat hosts of betacoronaviruses as a case study for the data-driven process of comparing and validating predictive models of probable reservoir hosts. In early 2020, we generated an ensemble of eight statistical models that predicted host–virus associations and …
