Trembling aspen (Populus tremuloides) is abundant in Canada but underutilized in non-structural solid wood products.This study was aimed at evaluating the feasibility of using aspen lumber to produce flooring, moulding, and siding. The shrinkage, surface roughness, and wettability of aspen wood were tested. The surface hardness, screw withdrawal resistance, colour change, and dimensional stability of there products fabricated were examined. The wood yield of each product was analyzed. It was found that aspen showed superior machinability and wettability to silver maple and yellow poplar. Aspen flooring had a Brinell hardness of 13.47 MPa, 60% lower than silver maple. …

Size Of Age-0 Sander Vitreus Pre And Post Dreissena Polymorpha Infestation On Brainerd And Bemidji Area Lakes, Quady Bernu

Journal of Earth and Life Science

Walleye Sander vitreus is the Minnesota state fish and a vital predator fish in lake ecology. Zebra mussels, Dreissena polymorpha were first found in Minnesota inland lakes in the 1980’s. These mussels have had huge impacts on water clarity as well as phytoplankton and zooplankton population levels which affect how age-0 fish feed, especially a low light feeding predator fish like walleye. A study took place on age-0 walleye size and it supported the conclusion that age-0 walleye were negatively impacted by zebra mussels in Minnesota’s large lakes. The goals of this study were to determine how the size of …

Microsatellites Reveal The Population Genetic Structure Of Yellow Perch In Minnesota, Megan Boche

Journal of Earth and Life Science

When analyzing a population’s genetic makeup, looking at variation of individuals and populations is a crucial factor. The management of yellow perch will be aided by this information particularly in regard to stocking or relocation. Microsatellite loci were used to analyze the genetic population structure of yellow perch Perca flavescens within and among 29 sampling areas throughout Minnesota’s basins. Seven microsatellite DNA loci were evaluated, with heterozygosities ranging from 0.41 to 0.78. The Lower Mississippi basin samples showed higher numbers of alleles per locus and greater expected heterozygosities compared to other basins, with Lake Pepin (PEP) exhibiting the highest average …

Homeostatic Influence Of Fig4 Outside Of The Fab1-Vac14-Fig4 Complex In Saccharomyces Cerevisiae, Hannah E. Reeves, Anna King, Imran Khan, Asha Thomas, Corey Chung, Anirudan Sivaprakash, Harrison A. Hall, Cole Mcguire, Victoria Cruz, Alim Habib, Lauren Dotson, Sophia R. Lee, Caroline L. Darbro, Bethany S. Strunk

Biology Faculty Research

The lipid phosphatase Fig4 is conserved in all eukaryotes and is associated with human neurological diseases for which there are currently no specific therapies. Fig4 functions in both the production and turnover of its lipid substrate, PI3,5P2, through participation in the Fab1-Vac14-Fig4 complex with its opposing kinase Fab1. The molecular mechanisms through which Fig4 influences PI3,5P2 production are not fully understood but are believed to require Fig4 binding to the scaffold protein Vac14. We unexpectedly found that multiple Fig4 disease-related mutants that are impaired in binding to the Fab1-Vac14-Fig4 complex dominantly confer tolerance to rapamycin, an inhibitor of the Target …

Developmental Regulation Of Corazonin, Eclosion Hormone, And Bursicon Messages And Rnai Suppression Of Corazonin In Adult Female American Dog Ticks, Dermacentor Variabilis, Anirudh Dhammi, Brooke Bissinger, Loganathan Ponnusamy, Daniel E. Sonenshine, R. Michael Roe

Biological Sciences Faculty Publications

The insect molting process is critical to growth and development and is regulated in part by the neuropeptides corazonin, eclosion hormone, and α and β bursicon. We found messages in a synganglion transcriptome from adult, female American dog ticks, Dermacentor variabilis (that do not molt), with a high similarity to the larval insect neuropeptides that control molting. The phylogenetic analysis of the tick putative neuropeptides compared to other arthropods is discussed in detail. The relative gene expression of these peptides was determined by quantitative PCR during the following adult developmental stages: (i) virgin, unfed 0–24 h after entering the adult …

Identification Of Pharmacophore Modifications That Enhance Bmp-Receptor Agonism, An Investigation To Understand The Development Of Potential Therapeutic Interventions, Maleka T. Stewart

Theses and Dissertations

Bone morphogenetic proteins (BMPs) are the largest subfamily of the Transforming Growth Factor (TGF)-ß superfamily. BMPs are renowned for their pivotal role in cellular functions such as cell growth, apoptosis, and differentiation. Yet, BMPs have also been attributed to the maintenance of adult tissue homeostasis. BMPs elicit physiological function at the cell membrane via a heterotetrameric complex composed of two Type I and two Type II serine-threonine kinase BMP receptors. Activation of BMP transmembrane receptors results in activation of either canonical (Smad-dependent) and/or non-canonical (Smad-independent) signaling. Given the physiological importance of this intricate communication between receptor activation and induction of …

Correction On The Status Of Nematodes Pavidus Horn, 1886 (Coleoptera: Eucnemidae: Dromaeolinae: Dromaeolini), With Redescriptions Of Two Species From The Southeastern United States And The Caribbean, Robert L. Otto

Insecta Mundi

The status of Nematodes pavidus Horn (Coleoptera: Eucnemidae), in relation to Nematodes punctatus LeConte and Nematodes teres Horn is being questioned after Muona (2000) revised the family in the Nearctic region. Investigations into the status of N. pavidus included explorations of the histories among these three species and examining images of the types through the Museum of Comparative Zoology’s website. It has been confirmed that Muona erred by synonymizing N. pavidus with N. teres before transferring both N. punctatus and N. teres to Dromaeolus Kiesenwetter. A correction has been made by transferring N. pavidus …

Three New Species Of Lepidocyrtus Bourlet (Collembola: Entomobryidae) From Florida, Usa, And Descriptive Notes On Lepidocyrtus Floridensis Snider, Felipe N. Soto-Adames, Emily Jenks, Kathryn M. Daly

Insecta Mundi

Abstract

In North America, the genus Lepidocyrtus Bourlet (Collembola: Entomobryidae) is represented by 18 species, but only three (L. floridensis Snider, L. millsi Snider, and L. pallidus Reuter) have been reported from Florida. We investigated species diversity in leaf litter samples from counties in the north-central and southern part of the state, as the reportedly low species diversity in Florida may be due to under-sampling. As a result, in this contribution we describe three species of Lepidocyrtus new to science: L. bobwoodruffi Soto-Adames, Jenks and Daly, new species, L. brambilae Soto-Adames, Jenks and …

Macroinvertebrate Community Dynamics In A Recovering, Hypersaline Estuary, Catherine M. Eckert, Claudia A. Tamez, Erin E. Easton, David W. Hicks

Gulf and Caribbean Research

The Bahia Grande is a 6,500—acre tidal basin located at the southernmost tip of Texas. Tidal flow into this coastal estuary was cut off in the 1930s, causing the basin to dry up for ~70 y. A pilot channel connecting the Bahia Grande to tidal waters was constructed in 2005, allowing flooding of the basin to occur. Throughout the period reported herein (2005–2019), the system remained characterized by persistent spatial and temporal episodes of extreme hypersalinity (>70)—a critical factor influencing estuarine community composition and driving key ecological processes. With additional rehabilitation actions forthcoming, characterization of the estuary is essential …

Lack Of Consistent Diurnal Trends In Acoustic Metrics From Restored Coral Reefs, Jeremy Velázquez-Alvarado, Valentina Pérez-García, Javier S. Tellechea, Joni T. Backstrom, Alex Mercado-Molina

Gulf and Caribbean Research

Once vibrant ecosystems, coral reefs are degrading at unprecedented rates due to natural and human—induced disturbances, necessitating immediate restoration and conservation efforts. Evaluating the success of these projects often involves assessing changes in reef biodiversity. Bioacoustics has emerged as a promising, non—invasive method for such evaluations, though its efficacy remains debated. This study aimed to determine whether the diurnal soundscapes of restored coral reefs are consistent across different time frames (months) and spatial scales (reefs), which is crucial for developing reliable monitoring tools for reef health. To achieve this, 2 commonly used acoustic indices, the Acoustic Complexity Index (ACI) and …

Elucidating The Genetic Regulation Of Zebrafish Type Ii Collagen Alpha 1 B, Angelina Renee Carcione

Dissertations

Type II collagens (Col2) are essential proteins providing flexibility and structure to vertebrate animals. During development type II collagens play a vital role in the formation of many structures, such as the cartilage of the skeleton, the notochord, the retina and many other tissues. Conserved throughout vertebrates, cartilage is composed of two main cell types: chondrocytes, which make up the bulk of the structure, and perichondral cells, which form the epithelial layer that surrounds chondrocytes and is essential for bone growth and joint protection. While much is known about the expression and regulation of type II collagens in chondrocytes, specifically …

Body Size Distributions Of Riverine Freshwater Plankton Communities, Staci Ann Reynolds

Dissertations and Theses

The individual size distribution (ISD) is an individual based model that estimates the relative abundance of individual body sizes in a community. ISD’s slope or lambda (λ) gives insight into the communities’ food web and energy transfer. Climate change is expected to shift mean body sizes and λ as it increases individuals’ energy demands. Alterations in food webs and spatial distribution throughout the middle Missouri River basin may also have an impact on these communities λ. In a mesocosm experiment and field study, planktonic communities were sampled and had body sizes measured. Generalized linear mixed models were fit to calculate …

Snake Venoms As Models For Understanding The Origins And Evolution Of Gene Regulatory Networks, Siddharth S. Gopalan

Biology Dissertations - Archive

Understanding the relationship between genotype and phenotype is a fundamental goal of biology. However, the vastly complex nature of eukaryotic gene regulation can make deriving precise relationships between genotype and phenotype challenging. The gene regulatory architecture of snake venom systems provide an opportunity to study this problem in a phenotypic system with immense variation in phenotypes and the underlying genetics. Using a set of integrated functional genomic approaches with snake venoms as a central model, in this dissertation, I provide several examples of the regulatory mechanisms by which diversity in phenotypes arises. Specifically, I identify how gene expression heterogeneity between …

Genetic Analysis Of Methionine Restriction-Associated Mitochondrial Unfolded Protein Response Signaling., Josh D. Dodge

Biology Dissertations - Archive

The lifespan of an organism is dictated by various genetic and environmental factors. One such determinant is the health of mitochondria which are organelles that mediate various critical cell functions including a significant role in generating the vast supply of cellular energy. Indeed, the gradual decline of mitochondrial function is believed to be a hallmark and possible cause of aging. Paradoxically, mild mitochondrial dysfunction early in life extends lifespan in various model organisms. Cells use diverse approaches to promote mitochondrial homeostasis, including the transcriptional reprogramming of cells by mitochondrial unfolded protein response (UPRmt) to mitigate mitochondrial stress. Consistently, UPRmt activation …

Utilizing Β-Gal To Visualize Selective Transport Of The Ssa4 Gene In S.Cerevisiae, Ian M. Staertow, Rebecca L. Adams Phd

Science University Research Symposium (SURS)

In eukaryotic cells such as Saccharomyces cerevisiae, protein synthesis begins with the transport of mRNA from the nucleus to the cytoplasm. In order for mRNA to leave the nucleus, it must first bind to specific transport proteins which can then facilitate transport via the nuclear pore complex (NPC), a selectively permeable membrane within the cell's nuclear envelope. Under environmental stress, such as heat shock, S. cerevisiae cells modulate transport rates. In this case, in heat stress or “heat shock” most mRNA transcripts will remain in the nucleus. The SSA4 transcript encodes for a chaperone protein which facilitates the subsequent export …
