Intelligent Approach To Power System Management During Well Drilling In Terms Of Environmental Impact, N N. Makhmudov, K M. Sulitanofu

Technical science and innovation

An autonomous hybrid power system is an intelligent power installation that provides electricity to isolated consumers without being connected to the power grid. The introduction of autonomous hybrid power systems in the oil and gas industry is considered as an option to improve energy and environmental security. As a rule, oil and gas fields are located remotely and off the grid, and therefore electricity is generated using diesel generators. This article discusses the possibility of reducing emissions of pollutants into the atmosphere by using an autonomous hybrid installation as a source of electrical energy.

Jews And Science, Sander L. Gilman

The Jewish Role in American Life: An Annual Review

Jews and Science examines the complicated relationship between Jewish identities and the evolving meanings of science throughout the history of Western academic culture. Jews have been not only the agents for study of things Jewish, but also the subject of examination by “scientists” across a range of disciplines, from biology and bioethics to anthropology and genetics. Even the most recent iteration of Jewish studies as an academic discipline—Israel studies—stresses the global cultural, economic, and social impact of Israeli science and medicine.

The 2022 volume of the Casden Institute’s Jewish Role in American Life series tackles a range of issues that …

Our Natural World, Jennifer Mattei

Biology Faculty Publications

It’s nothing earth-shattering to say our natural world gives us everything we need to survive, from the oxygen we breathe and the clean water we drink to that apple you are enjoying with your lunch today. We all know this. However, we sometimes fail to appreciate and act on the converse—if we fail to maintain a well-functioning and resilient natural world our future is literally at risk.

What’s more, our reliance on nature goes deeper than the base physical essentials of air, water and food that are required for life. Our bodies—physically, mentally and emotionally—are healthier for their interaction with …

Is Wild Rice The Correct Choice For Habitat Restoration In Little Rock Lake, Mn, A Managed Shallow Lake Ecosystem In The Upper Midwest, Mason D. Olinger, Matthew L. Julius, Matthew P. Davis, Tracy E. Ore

Culminating Projects in Biology

In this masters thesis, my work is focused on a lake located north of St. Cloud in Rice, Minnesota called Little Rock Lake. Here, I have exercised the idea of testing a model of wild rice growth in its correct ecological conditions. These conditions were soil type, water depth, day length, and nutrient level. Obtaining growth of wild rice according to these parameters required adjustments to the system’s nutrient imbalance. Little Rock Lake, like any shallow lake, suffers from severe eutrophication in their system which has changed the dynamics of their lake. Overloads of phosphorus in a water body change …

Ecology And Evolution Of Social Information Use, Clare T. M. Doherty

Dartmouth College Ph.D Dissertations

Sociality is a strategy many animals employ to cope with their environments, enabling them to survive and reproduce more successfully than would otherwise be possible. When navigating their environments and making decisions, social individuals often use information provided by conspecifics (in the form of social cues and signals), thereby increasing the scope and reliability of the information they can gather. However, social information use may be influenced by many factors, including key differences in context across the physical and social environment. My thesis asks and answers a series of questions regarding the trade-offs in social information use across different contexts, …

Occurrence Of Kanamycin-Resistant Bacteria Relative To Anthropogenic Pollution Along Richland Creek In Nashville, Tn​, Jolene Ho Mach, Annie Le, Brandon Torres Ramirez

Science University Research Symposium (SURS)

The overuse of antibiotics has caused an increase in antibiotic-resistant (AR) bacteria, which is a serious public health concern. Previous studies showed a significant correlation between anthropogenic pollution and AR bacteria. This project aims to identify AR bacteria in Richland Creek relative to local anthropogenic pollution. Water samples were collected at four locations along Richland Creek in Nashville, Tennessee. Bacteria resistant to the antibiotic kanamycin were isolated from the water samples, identified to genera using DNA barcoding, and compared among the sites. We expect to see a greater abundance and diversity of kanamycin-resistant bacteria closer to the end than near …

The Still Unfathomed Trans+Oceanic, Daze Jefferies

The Goose

For centuries, violence against mermaids has coexisted alongside slippery sexualizations in much of Newfoundland’s folk and popular cultures. This is demonstrated most grievously in colonist Richard Whitbourne’s 1620 text, A Discourse and Discovery of Newfoundland. The fishy reality of simultaneous disposability and desirability also mirrors the life histories of trans women and sex workers in the capital port city of St. John’s. Imagining mermaids as trans and sex-working ancestors in a province that has been structured by ecologies of fish trade, this work of research-creation drifts through precarious survival in the North Atlantic.

Environmental Influence On Stickleback Fish Phenotype, Alaina A. Young

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Abstract

Sticklebacks have grown to be a model organism in the last few decades because they have undergone a rapid adaptive radiation event. Portions of the original marine population have migrated to isolated freshwater ecosystems and their fundamental niche has expanded. Variation among select phenotypic traits is a direct result of selective pressures imposed by new environment types. Lateral plates have been the most widely analyzed trait, it is hypothesized that great variation in plate quantity has resulted from expansion events. Lateral plates are pieces of an exoskeleton in addition to the already established endoskeleton. This study aims to assess …

Niche Overlap In Sympatric Rocio (Teleostei: Cichlidae) Of Guatemala, Cesar Estuardo Fuentes Montejo

College of Science and Health Theses and Dissertations

Rocio is a small genus of Neotropical freshwater fishes that is distributed in Atlantic drainages of northern Middle America. Two species in the genus exhibit sympatry in the Río Dulce basin (in Izabal, Guatemala), where one species is endemic (R. spinosissima), while the other only includes this area as part of a larger geographic range (R. octofasciata). Unfortunately, the ecology of these species has been poorly studied. This study sought to determine the ecological and morphological differences between these two closely related sympatric freshwater fishes. We hypothesized that R. octofasciata would exhibit greater ecological and morphological …

Consequences Of Biofilm Architecture On Vibrio Cholerae Ecology And Life History, Benjamin Ray Wucher

Dartmouth College Ph.D Dissertations

The diversity of microbes and the environments they inhabit are staggering. In many of these environments, bacteria have evolved to form sessile surface attached communities called biofilms. These biofilms have wide reaching impacts from importance in global carbon cycling, to persistent catheter infections, to biofouling and wastewater treatment. While many species of microbes form biofilms to survive in their environment, the architectures of these structures vary widely between organisms. Even though a great deal of work has been done to understand bacterial communities and their functions, little work has examined how the spatial aspects of biofilm architecture can affect the …

A Study Of Red Snapper (Lutjanus Campechanus) Ecology In The Northern Gulf Of Mexico And The Effect Of Variable River Outflow Using Stable Isotope Analysis Of The Food Web And Eye Lenses, Caitlin C. Slife

Dissertations

In the Mississippi Bight and surrounding waters, river outflow impacts the basal resources of the Red Snapper food web, altering carbon sources and impacting prey and predator isotopes. In this study, the impact of riverine outflow on nutrients, particulate organic matter (POM), and physical water parameters on Red Snapper and their food web was analyzed using stable isotope and stomach content analysis over 5 years. The Mississippi, Pearl, Pascagoula, and Mobile rivers were included in the analysis of river impact. The Mississippi and Mobile rivers were found to significantly impact nutrients and POM in the region. River outflow was also …

Characterizing Habitat Suitability For Gulf Sturgeon (Acipenser Oxyrinchus Desotoi) In Southern Louisiana, Jenna N. Brogdon

LSU Master's Theses

A generalized additive modeling (GAM) framework was used to characterize fish-habitat relationships and develop habitat suitability maps to predict spatiotemporal and ontogenetic shifts in Gulf sturgeon distribution within an impacted estuary in the northern Gulf of Mexico, Lake Pontchartrain. Gulf sturgeon (n = 103) were fitted with acoustic transmitters in the Pearl River during the early summer and fall from 2013 to 2018, and an array of acoustic receivers (n = 81) was used to monitor Gulf sturgeon habitat use and movement in the estuary from 2016 to 2019. Daily presence data from the telemetry array were paired with environmental …

Prevalence Of Mortality Among Covid-19 Patients In Kurdistan Region And Various Parts Of The World And The Role Of Ecological And Environmental Factors In Shaping Sars-Cov-2 Virulence, Muayad A. Mahmud

Polytechnic Journal

Evolutionary theories predict that virulence (host death due to a pathogen) positively associates with the pathogen transmission rates to new susceptible hosts. Severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2), the causative agent of coronavirus disease 2019 (covid-19) pandemic, like other RNA viruses, has quite variable genetic content due to its unique nucleus enzymes thus mutations can continuously occur during viral replications. Phenotype variations among new viral progeny can include individuals with different replication rates, infectivity, stability in the abiotic environment, and transmission rate. Here, the rate of transmission to new susceptible hosts may be affected by the pathogen’s vitality …

Effects Of Mass Death On Community Structure And Ecosystem Function, Abby Kimpton Jones

Theses and Dissertations

Death and decomposition are natural processes that are generally well-understood. However, large events of death, such as mass mortality events (MMEs) are increasing in frequency and their impacts on the ecosystem are largely unknown. These events may have both bottom-up effects from increased nutrient input as well as top-down effects from loss of an ecological functional group by the affected population. Different functional MMEs may result in different top-down effects, creating cascading effects. In Chapter 1, I test the hypothesis that scavenger and herbivore simulated MMEs generate novel bottom-up and top-down effects. Results indicate that MMEs have a significant effect …

Quantifying Aboveground Biomass In A Tropical Forest Using A Lidar Waveform Weighted Allometric Model, Alejandro Rojas

Theses and Dissertations

Our knowledge of the distribution and amount of terrestrial above ground biomass (AGB) has increased using lidar technology. Recent advancements in satellite lidar has enabled global mapping of forest biomass and structure. However, there are large biases in satellite lidar estimates which impacts our understanding of carbon dynamics, particularly in tropical forests.

Ni-Meister et al. (2022) developed a lidar full waveform weighted height-based allometric model which produced very good results in temperate deciduous/conifer forest in the continental US. The purpose of this study was to evaluate this biomass model in an African tropical forest using the Land Vegetation and Ice …

18s-Nemabase: Curated 18s Rrna Database Of Nematode Sequences, Kaitlin Gattoni, Eli M. S. Gendron, Rebeca Sandoval- Ruiz, Abigail Borgemeier, J. Parr Mcqueen, Rachel M. Shepherd, Dieter Slos, Tom Powers, Dorota L. Porazinska

Department of Plant Pathology: Faculty Publications

Nematodes are the most abundant and diverse animals on the planet but lack representation in biodiversity research. This presents a problem for studying nematode diversity, particularly when molecular tools (i.e., barcoding and metabarcoding) rely on well-populated and curated reference databases, which are absent for nematodes. To improve molecular identification and the assessment of nematode diversity, we created and curated an 18S rRNA database specific to nematodes (18S-NemaBase) using sequences sourced from the most recent publicly available 18S rRNA SILVA v138 database. As part of the curation process, taxonomic strings were standardized to contain a fixed number of taxonomic ranks relevant …

Competing Behaviors Of Thermoregulation And Ambush Foraging In The Timber Rattlesnake (Crotalus Horridus Horridus): A Mechanistic Assessment Of Thermal Conduction, Larry K. Kamees

Graduate Theses and Dissertations

The interaction between the biophysical environment and ectotherm morphology elicits behaviors designed to maintain internal body temperature (Tb) within a range that promotes physiological functions. The short-term requirements of mass (energy requirements) and heat balance are subject to tradeoffs imposed by the organisms current physiological (heat and mass budgets) and environmental (biophysical, demographic, social, and predation) constraints and available resources. In temperate forests, extreme temperatures are common in summer even with intermittent sun exposure due to dense canopy cover. In Spring and Fall, temperatures can range from below freezing to 35 ℃ in 24 hrs. An ambush predator like the …

Writing An Existential Novel: An Environmental And Philosophical Exploration, Julia Whinston

Honors College

Halfway Through the Wood is a creative project guided by the question, does nature have intrinsic ethical, philosophical, and/or spiritual value, or do we project it there? As a subsidiary question, is our relationship with nature akin to our relationship with ourselves? The novel begins with a “man versus nature” conflict, exploring human relationships to land, then moves on to a conversation about self, which ultimately leads to an incredulous/existential discourse about interconnectedness. The novel explores the implications of experiencing grief alongside natural systems, and concludes that enmeshing oneself within a natural system is vital for discovering meaning after experiencing …

Classifying The 2022 Status Of Tsuga Canadensis (Eastern Hemlock) Along The Kentucky Portion Of The Pine Mountain Wildlands Corridor., Grace M. Embree

Electronic Theses and Dissertations

The invasion of the Hemlock Woolly Adelgid (HWA) (Adelges tsugae) has posed a continual threat in the United States to the Eastern Hemlock (Tsuga canadensis) trees since the 1950s. HWA feed on eastern hemlock needles, reducing the amount of healthy photosynthesizing vegetative area. The use of satellite imagery has been instrumental in identifying areas of eastern hemlock presence. Satellite platforms like Landsat and AVIRIS are commonly used for identification, classification, and mapping of eastern hemlock. Sentinel-2 imagery was released in 2015 for free access. It has a finer spatial grain of with the majority of the …

Regional-Scale Climate-Induced Variation In Ant Physiology And Morphology, Daniel E. Murphy

Biology Theses

The biology of ectotherms such as insects is influenced by ambient thermal conditions. Ants are a ubiquitous and ecologically important group of insects and are well-established as bioindicators of thermal conditions. Ants are sensitive to the thermal extremes that vary with latitude, elevation, and land use, and these thermal gradients influence their spatial and temporal distributions. As a result, ants have evolved physiological and morphological thermal adaptations in response to the thermal environment of their habitats. These adaptations include increased physiological and morphological tolerance for temperature extremes. In Western New York (WNY), temperatures are temporally and spatially heterogeneous, changing with …

Assessing The Effects Of Elevation On The Peaks Of Otter Salamander (Plethodon Hubrichti) Using Body Condition Index, Norman Reichenbach, Timothy R. Brophy, Hannah Suber, Elisabeth Russell, Hannah Kinsley, Liam Cusack, Cetia Dawson, Savannah Dunn, Olivia De Araujo

Faculty Publications and Presentations

The Peaks of Otter Salamander (Plethodon hubrichti; POS) is a montane species found at elevations above 442 m within a 117 km2 area of the Blue Ridge Mountains in central Virginia. In allopatric areas (areas without the Eastern Red-backed Salamander, P. cinereus, a known competitor), POS body condition was hypothesized to decline both above and below some optimal elevation. Decreased condition at lower elevations would most likely be due to increased temperatures and lower relative humidities, which may adversely affect the ability of salamanders to forage effectively on vegetation due to desiccation risk. Decreased condition at elevations above …

Nature, Data, And Power: How Hegemonies Shaped This Special Section, A. Kamath, B. Velocci, A. Wesner, N. Chen, Vincent A. Formica, B. Subramaniam, M. Rebolleda-Gómez

Biology Faculty Works

Systems of oppression—racism, colonialism, misogyny, cissexism, ableism, heteronormativity, and more—have long shaped the content and practice of science. But opportunities to reckon with these influences are rarely found within academic science, even though such critiques are well developed in the social sciences and humanities. In this special section, we attempt to bring cross-disciplinary conversations among ecology, evolution, behavior, and genetics on the one hand and critical perspectives from the social sciences and humanities on the other into the pages—and in front of the readers—of a scientific journal. In this introduction to the special section, we recount and reflect on the …

Disturbance Ecology Of The Sonadora River Rock Pool Insect Assemblage At Luquillo Experimental Forest, Puerto Rico, Patrick Gilkey

Master's Theses

Freshwater rock pools can serve as habitat for aquatic insects. Flash-flooding can have profound effects on insect communities in streams and rivers, but these effects have not been studied on freshwater rock pools. The goal of this thesis was to describe ecological patterns of the Sonadora River rock pool insect community at the Luquillo Experiment Forrest, Puerto Rico, specifically in response to intense flash-flooding, and then perform experiments to elucidate possible processes to explain those patterns. The rock pools contained primarily three taxa of Dipteran (true-fly) larvae, in order of decreasing abundance, 1) a newly discovered species of ceratopogonid (biting …

Distribution And Ecological Function Of Pacific Lamprey In The San Luis Obispo Creek Watershed, Parker Kalan

Master's Theses

Pacific lamprey (Entosphenus tridentatus) is an endemic species to coastal watersheds along the Pacific Rim in North America and Asia. The species' geographic distribution is retracting and has not been mapped precisely, and the ability for the species to provide ecosystem services, such as water filtration, for supporting watershed management has not been tested. The San Luis Obispo Creek watershed, California, USA is at the southern end of Pacific lamprey’s retracting distribution, and the San Luis Obispo watershed is impacted by degraded water quality, making investigation of Pacific lamprey in the San Luis Obispo Creek watershed of direct …
