Maternal Lineage And Habitat Use Patterns Explain Variation In The Fecundity Of A Critically Endangered Baleen Whale, Ana L. Bishop, Leah M. Crowe, Philip K. Hamilton, Erin L. Meyer-Gutbrod

Faculty Publications

The critically endangered North Atlantic right whale population (Eubalaena glacialis) has experienced multiple periods of decreased reproduction within its observable history, which have played a role in the overall decline of the species. In addition to this synchronized variation in reproduction across the population, there exists considerable individual variation in fecundity. To determine the impacts of family history and habitat use behavior on these individual variations in fecundity, photo identification data collected during four decades of visual monitoring were used to create a calving index for sexually mature females that could be used to evaluate matrilineal influence on …

Host Gut Resistome In Gulf War Chronic Multisymptom Illness Correlates With Persistent Inflammation, Dipro Bose, Somdatta Chatterjee, Ethan Older, Ratanesh Seth, Patricia Janulewicz, Punnag Saha, Ayan Mondal, Jeffrey M.

Climate change is a pervasive threat to biodiversity. While range shifts are a known consequence of climate warming contributing to regional community change, less is known about how species’ positions shift within their climatic niches. Furthermore, whether the relative importance of different climatic variables prompting such shifts varies with changing climate remains unclear. Here we analysed four decades of data for 1,478 species of birds, mammals, butterflies, moths, plants and phytoplankton along a 1,200 km high latitudinal gradient. The relative importance of climatic drivers varied non-uniformly with progressing climate change. While species turnover among decades was limited, the relative position …

A Century-Long Trajectory Of Phosphorus Loading And Export From Mississippi River Basin To The Gulf Of Mexico: Contributions Of Multiple Environmental Changes, Zihao Bian, Shufen Pan, Zhuonan Wang, Yuanzhi Yao, Rongting Xu, Hao Shi, Latif Kalin, Christopher Anderson, Dubravko Justic, Steven Lohrenz, Hanqin Tian

Faculty Publications

Phosphorus (P) control is critical to mitigating eutrophication in aquatic ecosystems, but the effectiveness of controlling P export from soils has been limited by our poor understanding of P dynamics along the land-ocean aquatic continuum as well as the lack of well-developed process models that effectively couple terrestrial and aquatic biogeochemical P processes. Here, we coupled riverine P biogeochemical processes and water transport with terrestrial processes within the framework of the Dynamic Land Ecosystem Model to assess how multiple environmental changes, including fertilizer and manure P uses, land use, climate, and atmospheric CO2, have affected the long-term dynamics of P …

Victims As Instruments, Rachel J. Wechsler

Faculty Publications

Crime victims are often instrumentalized within the criminal legal process in furtherance of state prosecutorial interests. This is a particularly salient issue concerning victims of gender-based violence (GBV) because victim testimony is typically considered essential for successful prosecution of these types of crimes. Since the U.S. Supreme Court's 2004 decision in Crawford v. Washington, courts require declarants to be available for cross-examination on "testimonial" hearsay evidence. Consequently, criminal legal actors are further incentivized to employ highly coercive practices aimed at securing GBV victims' participation in the criminal legal process as evidentiary tools. These practices include arresting and incarcerating victims through …

Phylogenetic Characterization And Genome Sequence Analysis Of Burkholderia Glumae Strains Isolated In Thailand As The Causal Agent Of Rice Bacterial Panicle Blight, Nootjarin Jungkhun, Antonio Roberto Gomes De Farias, Jutatape Watcharachaiyakup, Nuttima Kositcharoenkul, Jong Hyun Ham, Sujin Patarapuwadol

Faculty Publications

Burkholderia glumae is one of the most critical rice-pathogenic bacteria, and it causes bacterial panicle blight (BPB) in rice plants. In 2017, BPB symptoms were observed from rice fields in Chiang Rai, Northern Thailand. Sixty-one isolates obtained from the symptomatic panicles of rice were initially identified as B. glumae by polymerase chain reaction (PCR) using species-specific primers. Among them, six selected strains isolated from the susceptible japonica rice cultivar DOA2 were characterized in terms of morpho-physiology, pathology, phylogenetics, and genomics. Our genome sequence analysis of the six selected strains revealed the presence of multiple prophages, which may reflect the high …

Influence Of Weather On Gobbling Activity Of Male Wild Turkeys, Patrick H. Wightman, James A. Martin, John C. Kilgo, Emily Rushton, Bret A. Collier, Michael J. Chamberlain

Faculty Publications

Gobbling activity of Eastern wild turkeys (Meleagris gallopavo silvestris; hereafter, turkeys) has been widely studied, focusing on drivers of daily variation. Weather variables are widely believed to influence gobbling activity, but results across studies are contradictory and often equivocal, leading to uncertainty in the relative contribution of weather variables to daily fluctuations in gobbling activity. Previous works relied on road-based auditory surveys to collect gobbling data, which limits data consistency, duration, and quantity due to logistical difficulties associated with human observers and restricted sampling frames. Development of new methods using autonomous recording units (ARUs) allows researchers to collect continuous data …

Recursive Movements Of Eastern Wild Turkey Broods In The Southeastern United States, Nicholas W. Bakner, Bradley S. Cohen, Bret A. Collier, Michael J. Chamberlain

Faculty Publications

Productivity of wild turkey (Meleagris gallopavo) populations throughout the southeastern United States has declined over the past several decades. Although population trajectory is driven primarily by annual reproduction, wild turkey managers have little information regarding the behavioral ecology of broods immediately post-hatch. Broods are known to revisit areas within their ranges, but revisitation behavior is poorly understood spatially and temporally. Thus, identifying patterns of visitation and revisitation can increase understanding of brood behavior. We monitored 94 brooding females until brood failure or 28 days after hatch to evaluate movements and to quantify landcover and vegetation density at revisited locations which …

Haxton, William Kelso, Nancy Leonard, Chris Lido, Joseph Margraf, Michael Porter, Casey Pennock, David Propst, Jared Ross, Michelle D. Staudinger, Gary Whelan, Dana M. Infante

Faculty Publications

Aim: Migratory freshwater fishes are those that must access discrete habitats to complete their life cycles. Freshwater fish migrations occur around the world and provide numerous ecosystem services for humans and natural systems; however, many migratory species are in decline globally. A limiting factor to successfully conserve freshwater migratory fishes is that the migratory life histories of many species are unknown or only partially described. To provide researchers with critical and comprehensive information to conserve migratory fishes, we developed the North American Freshwater Migratory Fish Database (NAFMFD). Location: Canada, Mexico and the United States. Taxon: Freshwater fish. Methods: To develop …

Interindividual Variation In Maximum Aerobic Metabolism Varies With Gill Morphology And Myocardial Bioenergetics In Gulf Killifish, Bernard B. Rees, Jessica E. Reemeyer, Brian A. Irving

Faculty Publications

This study asked whether interindividual variation in maximum and standard aerobic metabolic rates of the Gulf killifish, Fundulus grandis, correlates with gill morphology and cardiac mitochondrial bioenergetics, traits reflecting critical steps in the O2 transport cascade from the environment to the tissues. Maximum metabolic rate (MMR) was positively related to body mass, total gill filament length and myocardial oxygen consumption during maximum oxidative phosphorylation (multiple R2=0.836). Standard metabolic rate (SMR) was positively related to body mass, total gill filament length and myocardial oxygen consumption during maximum electron transport system activity (multiple R2=0.717). After controlling for body mass, individuals with longer …

Trauma And Poetry. The Case Of Primo Levi, Ilona Klein

Faculty Publications

Most North American readers have come to know and appreciate Primo Levi by his major works in prose. His The Periodic Table (1984) catapulted Levi onto the American stage of scientific-humanistic authors, having the New York Times named it among the Best Books of the Year in 1985. Instead, American readers will likely stumble upon Levi’s poetry by accident, simply because every now and then one of his poems in translation appears in print somewhere. Compared to Levi’s prose, his poems inevitably evoke a sense of unease, for their tone, their style and their content are so unlike the familiar, …

The Lsu Campus Mounds, With Construction Beginning At ~11,000 Bp, Are The Oldest Known Extant Man-Made Structures In The Americas, Brooks B. Ellwood, Sophie Warny, Rebecca A. Hackworth, Suzanne H. Ellwood, Jonathan H. Tomkin, Samuel J. Bentley, Dewitt H. Braud, Geoffrey C. Clayton

Faculty Publications

Radiocarbon dating of the two LSU Campus Mounds (16EBR6) indicates that the construction of one, Mound B, began at ~11,000 BP, making Mound B the oldest known and intact manmade structure in the Americas. The age analyses preesented here are based on thirty one 14C dates. The older (deeper) parts of both of the LSU Campus Mounds contain many thin, burned ash lenses, suggesting that the Mounds may have been used for ceremonial or cremation purposes. These ash layers are composed mainly of phytoliths, bio-silicate (SiO2) structural compounds in plants that remained after burning of these plants. Analysis of the …

Comparison Of Microstructure And Tensile Behavior Of Hydroxyapatite-Coated Peek Meshes And Cellulose-Based Fabrics And Mats, Armaghan Naderi, Genevieve Palardy

Faculty Publications

Polymeric biomaterials, such as polyether ether ketone (PEEK) and cellulose, have been explored as scaffolds for bone tissue engineering in the past decade. In this study, microstructure and mechanical behavior of uncoated and hydroxyapatite (HA)-coated polymeric meshes, fabrics, and mats were investigated. Commercially available monofilament PEEK meshes, and cellulose fabrics and mats were selected, then coated with a customized low temperature sol–gel method (≤ 150°C). Adhesive HA coating consisting of HA, β-TCP, and CaO with nanorod structure was derived. After HA coating, porosity of substrates (except filter-paper cellulose mats) decreased by up to 43%, indicating effective coating. Both uncoated and …

Effects Of Bromocriptine On Glucose And Insulin Dynamics In Normal And Insulin Dysregulated Horses, Caroline M.M. Loos, Kristine L. Urschel, Eric S. Vanzant, Erin L. Oberhaus, Adam D. Bohannan, James L. Klotz, Kyle R. Mcleod

Faculty Publications

The objectives of the study were to study the effects of the synthetic ergot alkaloid (EA), bromocriptine, on glucose and lipid metabolism in insulin dysregulated (ID, n = 7) and non-ID (n = 8) mares. Horses were individually housed and fed timothy grass hay and two daily concentrate meals so that the total diet provided 120% of daily DE requirements for maintenance. All horses were given intramuscular bromocriptine injections (0.1 mg/kg BW) every 3 days for 14 days. Before and after 14 days of treatment horses underwent a combined glucose-insulin tolerance test (CGIT) to assess insulin sensitivity and a feed …

The Reproductive Biology Of Small Fishes And The Clutch Concept: Combining Macroscopic And Histological Approaches, David C. Heins, Nancy J. Brown-Peterson

Faculty Publications

Accurate estimates of reproductive parameters important in understanding life history evolution and conservation of small fishes are dependent upon careful assignment of ovarian phases. Proper assignment is based upon the stages of propagule (oocyte) development, oocyte maturation and the location of any clutch or portion thereof within the ovaries. Macroscopic inspection and assignment of ovarian developmental phases have often been used for small freshwater fishes. By contrast, histological methods for assignment of reproductive phases have been developed and are widely used for marine fishes, but they have rarely been used for small freshwater fishes. We review oocyte development, ovum maturation, …

Faculty Publications

The barn swallow (Hirundo rustica) poses a number of fascinating scientific questions, including the taxonomic status of postulated subspecies. Here, we obtained and assessed the sequence variation of 411 complete mitogenomes, mainly from the European H. r. rustica, but other subspecies as well. In almost every case, we observed subspecies-specific haplogroups, which we employed together with estimated radiation times to postulate a model for the geographical and temporal worldwide spread of the species. The female barn swallow carrying the Hirundo rustica ancestral mitogenome left Africa (or its vicinity) around 280 thousand years ago (kya), and her descendants …

Cross-Modal Perception Of Identity By Sound And Taste In Bottlenose Dolphins, Jason N. Bruck, Sam F. Walmsley, Vincent M. Janik

Faculty Publications

While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions. To investigate whether other animals use labels comparably, we studied cross-modal, individual recognition in bottlenose dolphins (Tursiops truncatus) that use signature whistles as labels for conspecifics in their own communication. First, we tested whether dolphins could use gustatory stimuli and found that they could distinguish between water and urine samples, as well as between urine from familiar and unfamiliar individuals. Then, we paired playbacks of signature whistles of known animals with urine samples from either the same …

Recent findings Studies have further validated the use of fluconazole for IC prophylaxis among high-risk patients in the NICU. It remains unclear if prophylaxis leads to resistance development and the ideal dosage regimen is still not clear. Recent studies have been published comparing caspofungin and micafungin to amphotericin B and illustrated similar efficacy outcomes in the NICU. Micafungin now has approval from the United …

Identification Of Micrornas In The Lyme Disease Vector Ixodes Scapularis, Deepak Kumar, Latoyia P. Downs, Monica Embers, Alex Sutton Flynt, Shahid Karim

Faculty Publications

MicroRNAs (miRNAs) are a class of small non-coding RNAs involved in many biological processes, including the immune pathways that control bacterial, parasitic, and viral infections. Pathogens probably modify host miRNAs to facilitate successful infection, so they might be useful targets for vaccination strategies. There are few data on differentially expressed miRNAs in the black-legged tick Ixodes scapularis after infection with Borrelia burgdorferi, the causative agent of Lyme disease in the United States. Small RNA sequencing and qRT-PCR analysis were used to identify and validate differentially expressed I. scapularis salivary miRNAs. Small RNA-seq yielded 133,465,828 (≥18 nucleotides) and 163,852,135 (≥18 …

Branching Off: New Insight Into Lysosomes As Tubular Organelles, K A. Bohnert, A E. Johnson

Faculty Publications

Lysosomes are acidic, membrane-bound organelles that play essential roles in cellular quality control, metabolism, and signaling. The lysosomes of a cell are commonly depicted as vesicular organelles. Yet, lysosomes in fact show a high degree of ultrastructural heterogeneity. In some biological contexts, lysosome membranes naturally transform into tubular, non-vesicular morphologies. Though the purpose and regulation of tubular lysosomes has been historically understudied, emerging evidence suggests that tubular lysosomes may carry out unique activities, both degradative and non-degradative, that are critical to cell behavior, function, and viability. Here, we discuss recent advances in understanding the biological significance of tubular lysosomes in …

Oxen: Status, Uses And Practices In The U.S.A., Encouraging A Historic Tradition To Thrive, Andrew B. Conroy

Faculty Publications

Oxen in the United States of America have played an important role throughout its history. Unlike other countries,oxen were never completely given up for horses, mules, or tractors. Instead, the culture of keeping oxen has been maintained by a small group of teamsters in the North- eastern states collectively called New England. Their continued presence has been largely due to agricultural fairs and exhibitions where they have been used in competition for the last 200 years. Ox teamsters were sur- veyed in 2021via social media using Qualtrics. The 423 ox teamsters responding owned 1791 oxen in 39 states, with the …

Zoos and natural history museums are both collections-based institutions with important missions in biodiversity research and education. Animals in zoos are a repository and living record of the world's biodiversity, whereas natural history museums are a permanent historical record of snapshots of biodiversity in time. Surprisingly, despite significant overlap in institutional missions, formal partnerships between these institution types are infrequent. Life history information, pedigrees, and medical records maintained at zoos should be seen as complementary to historical records of morphology, genetics, and distribution kept at museums. Through examining both institution types, we synthesize the benefits and challenges of cross-institutional exchanges …

Value-Added Utilization Of Wheat Straw: From Cellulose And Cellulose Nanofiber To All-Cellulose Nanocomposite Film, Hongxia Bian, Yanyan Yang, Peng Tu, Jonathan Y. Chen

Faculty Publications

To accelerate the high value-added usage of agricultural residue, cellulose and cellulose nanofibers (CNFs) were extracted from wheat straw and then formed into all-cellulose nanocomposite films. The acid–alkali method (AM) and the extraction method (EM) were respectively adopted to prepare wheat straw cellulose (WSC), and the TEMPO oxidation method was used to extract CNFs. The nanocomposite films were fabricated by dissolving WSC and adding different CNF contents of 0.0, 0.5, 1.5, and 3.0%. There was a better miscibility for the all-cellulose nanocomposite film prepared by EM (Composite-E) compared to that for the all-cellulose nanocomposite film prepared by AM (Composite-A). Composite-E …

Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series data from across the globe and makes these data freely available to the community. MASTREE+ includes 73,828 georeferenced observations of annual reproduction (e.g. seed and fruit counts) in perennial plant populations worldwide. These observations consist of 5971 population-level time-series from 974 species in 66 countries. The mean and median time-series length is …

Land Rich, Cash Poor: Hispanic Subsistence Agri-Culture On Acequia Farms Of Northern New Mexico, 1880-1950s, José A. Rivera Ph.D.

Faculty Publications

Acequia-based agriculture in Hispanic northern New Mexico originated with the arrival of settlers from the central valley of Mexico in the late sixteenth century and later following the Camino Real into the upper Río Grande and its tributaries. The high desert environment required irrigation for food production and survival. Land parcels in the rural villages of northern New Mexico were small, and crop yields were limited to home consumption on a subsistence basis, an economy that lasted well into the territorial period and statehood of New Mexico. Despite a wage economy introduced with the arrival of the railroad around 1880 …
