Over a century ago, copper mills on the Keweenaw Peninsula of Lake Superior sluiced 64 million metric tonnes (MMT) of tailings into coastal waters, creating a metal-rich “halo”. Here we show that relatively small discharges can spread widely in time and space. Mass Mill (2.9 MMT) dumping into Lake Superior also illustrates the complexity of interactions with Indigenous Peoples. A combination of aerial photos, LiDAR, and a microscope technique for distinguishing end-member particles traces the migration of tailings. The clay fraction spread rapidly across Keweenaw Bay and curled into terminal L’Anse Bay, within tribal Reservation boundaries. The coarse stamp sand …

School of Biological and Marine Sciences

Degradation of the natural world and associated ecosystem services is attributed to a historical failure to include its ‘value’ in decision-making. Uncertainty in the quantification of the relationship between natural capital ‘assets’ that give rise to critical societal benefits and people is one reason for the omission of these values from natural resource management. As this uncertainty increases in marine systems and further still with distance from the coast, the connection between society and natural capital assets is less likely to be included adequately in decision-making. Natural capital assets of Areas Beyond National Jurisdiction (ABNJ), including those of the deep …

Nebraska Center for Virology: Faculty Publications

SARS-CoV-2 belongs to the family Coronaviridae which includes multiple human pathogens that have an outsized impact on aging populations. As a novel human pathogen, SARS-CoV-2 is undergoing continuous adaptation to this new host species and there is evidence of this throughout the scientific and public literature. However, most investigations of SARS-CoV-2 evolution have focused on largescale collections of data across diverse populations and/or living environments. Here we investigate SARS-CoV-2 evolution in epidemiologically linked individuals within a single outbreak at a skilled nursing facility beginning with initial introduction of the pathogen. The data demonstrate that SARSCoV- 2 was introduced to the …

Pharmacy Faculty Articles and Research

One group of the K+ ion channels, the small-conductance Ca2+-activated potassium channels (KCa2.x, also known as SK channels family), is widely expressed in neurons as well as the heart, endothelial cells, etc. They are named small-conductance Ca2+-activated potassium channels (SK channels) due to their comparatively low single-channel conductance of about ~10 pS. These channels are insensitive to changes in membrane potential and are activated solely by rises in the intracellular Ca2+. According to the phylogenic research done on the KCa2.x channels family, there are three channels' subtypes: KCa2.1, K …

Background Microbes constitute almost the entire biological community in subsurface groundwater and play an important role in ecological evolution and global biogeochemical cycles. Ecological baseline as a fundamental reference with less human interference has been investigated in surface ecosystems such as soils, rivers, and ocean, but the existence of groundwater microbial ecological baseline (GMEB) is still an open question so far. Results Based on high-throughput sequencing information derived from national monitoring of 733 newly constructed wells, we find that bacterial communities in pristine groundwater exhibit a significant lateral diversity gradient and gradually approach the topsoil microbial latitudinal diversity gradient with …


Regional Aquatic Macroinvertebrate Biodiversity, Sally Sir, Kris N. White Ph.D. Jul 2023

Regional Aquatic Macroinvertebrate Biodiversity, Sally Sir, Kris N. White Ph.D.

Georgia Journal of Science

Macroinvertebrates are sensitive to environmental conditions, giving them the ability to be utilized in studies indicating the health of their environment. Additionally, macroinvertebrates are an important food source for vertebrates and invertebrates. Since macroinvertebrates play such significant roles in the ecosystem, it is important to identify and document their presence. In order to begin documenting the macroinvertebrates in central Georgia, aquatic macroinvertebrates were collected from ten sampling sites along a transect of central Georgia. Live specimens were imaged, preserved, identified, and sequenced. COI mitochondrial DNA and 18s nuclear DNA and 3D images of the organisms were made publicly available. The …


Sustainability Of Permanent Grassland On A Low Moor Soil With Different N And K Nutrient Management, K. Orlovius, J. Pickert Jul 2023

Sustainability Of Permanent Grassland On A Low Moor Soil With Different N And K Nutrient Management, K. Orlovius, J. Pickert

IGC Proceedings (1977-2023)

After the reunification of Germany fertilisation with P and K was strongly reduced in the eastern states of Germany due to the poor financial situation of the farms. Particularly on sites with a low nutrient delivery capacity, such a nutrient management strategy implies the risk of decreasing soil fertility. On a low moor soil with permanent grassland a 4 - year trial with different N and K fertilisation was set up to study the development of dry matter production and K concentrations in the grass.

Background Recent evidence implicates inflammation as a key driver in delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage (SAH). Inducible nitric oxide synthase (iNOS) is one of the known major mediators of inflammation. We previously showed that an inhalational anesthetic, isoflurane, provides strong protection against delayed cerebral ischemia after SAH. Our current study aims to define the role of iNOS in isoflurane conditioning-induced protection against delayed cerebral ischemia in a mouse model of SAH. Methods and Results The experiments used 10- to 14-week-old male wild-type (C57BL/6) and iNOS global knockout mice. Anesthetic conditioning was initiated 1 hour after SAH with isoflurane …

Testing The Urban Dulling Hypothesis In An Iridescent Passerine Bird, Joanna Gresham Jul 2023

Testing The Urban Dulling Hypothesis In An Iridescent Passerine Bird, Joanna Gresham

Master of Science in Integrative Biology Theses

Urbanization has brought grave consequences that lead to declines in many species; however, some species thrive in urban ecosystems. This allows us the opportunity to study evolution in real time, as species adapt and change in a new setting. Novel urban ecosystems have led to phenotypic divergence between urban and rural populations. There is a rich body of literature on how songbirds are affected by urbanization, however divergent signaling behaviors are less well understood. Urban color homogenization is well-documented in carotenoid-colored species. However, iridescent plumage is understudied in general, and little is understood about how environmental changes shape iridescent plumage. …

School of Biological Sciences: Faculty Publications

The number of tRNAs encoded in plant mitochondrial genomes varies considerably. Ongoing loss of bacterial-like mitochondrial tRNA genes in many lineages necessitates the import of nuclear-encoded counterparts that share little sequence similarity. Because tRNAs are involved in highly specific molecular interactions, this replacement process raises questions about the identity and trafficking of enzymes necessary for the maturation and function of newly imported tRNAs. In particular, the aminoacyl-tRNA synthetases (aaRSs) that charge tRNAs are usually divided into distinct classes that specialize on either organellar (mitochondrial and plastid) or nuclear-encoded (cytosolic) tRNAs. Here, we investigate the evolution of aaRS subcellular localization in …

Calcium Carbonate As A Potential Intervention To Prevent Labor Dystocia: Narrative Review Of The Literature, Sabahat Raees, Marie Forgie, Rita Mitchell, Emily Malloy

Journal of Patient-Centered Research and Reviews

Anecdotally, there are attestations from clinicians of calcium carbonate being used successfully for laboring people experiencing labor dystocia. The goal of this narrative review was to provide a synopsis of pertinent literature on calcium use in obstetrics to explore the potential benefit of calcium carbonate as a simple and low-cost intervention for prevention or treatment of labor dystocia. To answer how calcium and carbonate physiologically contribute to myometrium contractility, we conducted a literature search of English-language peer-reviewed articles, with no year limitation, consisting of the keywords “calcium,” “calcium carbonate,” “calcium gluconate,” “pregnancy,” “hemorrhage,” and variations of “smooth muscle contractility” and …

Age-related macular degeneration (AMD) is a leading cause of blindness in older adults. Investigating shared genetic components between metabolites and AMD can enhance our understanding of its pathogenesis. We conduct metabolite genome-wide association studies (mGWASs) using multi-ethnic genetic and metabolomic data from up to 28,000 participants. With bidirectional Mendelian randomization analysis involving 16,144 advanced AMD cases and 17,832 controls, we identify 108 putatively causal relationships between plasma metabolites and advanced AMD. These metabolites are enriched in glycerophospholipid metabolism, lysophospholipid, triradylcglycerol, and long chain polyunsaturated fatty acid pathways. Bayesian genetic colocalization analysis and a customized metabolome-wide association approach prioritize putative causal …

Defeat, Entrapment, And Suicide Desire: Analyzing The Role Of Mindfulness Using Ecological Momentary Assessment., Emma H. Moscardini Jul 2023

Defeat, Entrapment, And Suicide Desire: Analyzing The Role Of Mindfulness Using Ecological Momentary Assessment., Emma H. Moscardini

LSU Doctoral Dissertations

Extant literature has indicated that the experience of defeat confers risk for experiencing conceptions of entrapment, which in turns increases one’s risk of experiencing suicidal ideation. In addition, certain cognitive processes are hypothesized to increase or decrease the likelihood of feelings of entrapment emerging when one feels defeated. One such cognitive process is mindfulness, defined as present moment awareness with an orientation of openness and acceptance. Better understanding the interplay of defeat, entrapment, mindfulness, and suicidal thinking will contribute to intervention strategies aimed at reducing the severity of suicidal thinking; however, said research should be conducted with consideration that one’s …

Background PacBio high fidelity (HiFi) sequencing reads are both long (15–20 kb) and highly accurate (> Q20). Because of these properties, they have revolutionised genome assembly leading to more accurate and contiguous genomes. In eukaryotes the mitochondrial genome is sequenced alongside the nuclear genome often at very high coverage. A dedicated tool for mitochondrial genome assembly using HiFi reads is still missing. Results MitoHiFi was developed within the Darwin Tree of Life Project to assemble mitochondrial genomes from the HiFi reads generated for target species. The input for MitoHiFi is either the raw reads or the assembled contigs, and the …

School of Biological and Marine Sciences

Subterranean life is associated with strong adaptive constraints, leading to the frequent occurrence of morphologically cryptic lineages. This is true of most small mammals, including moles (Eulipotyphla: Talpidae), where a number of species have been recognized recently, particularly following the application of molecular genetics. Here, we use mitochondrial and nuclear DNA sequence data and geometric morphometrics to explore the systematics and evolution of some of the least-known Western Palaearctic moles: the Talpa davidiana group of Eastern Anatolia/Iran. We show that T. davidiana includes four taxa, two of which we describe herein: T. hakkariensis sp. nov., T. davidiana davidiana, T. davidiana …
