Delayed Effects Of Sub-Lethal Lampricide, 3-Trifluoromethyl-4-Nitrophenol (Tfm), Exposure On The Metabolic Physiology Of Juvenile Lake Sturgeon (Acipenser Fulvescens), Matthew J. Symbal

All NMU Master's Theses

The lampricide 3-trifluoromethyl-4-nitrophenol (TFM) can be lethal to juvenile lake sturgeon (Acipenser fulvescens) at high concentrations used to control invasive sea lamprey (Petromyzon marinus). Little is known about how TFM would affect juvenile lake sturgeon (age-0) at the sub-lethal concentrations encountered during routine lampricide treatments; specifically, its effects on growth, stress response, and metabolism. Age-0 lake sturgeon were exposed to TFM concentrations at levels 0.0x, 0.5x, and 1.0x the minimum lethal concentration (mlc) of TFM required to kill 99.9% of sea lamprey larvae during a routine stream treatment. The mlc was estimated based on pH and alkalinity …

Effects Of Ocean Warming And Acidification On Fertilization Success And Early Larval Development In The Green Sea Urchin, Lytechinus Variegatus, Brittney L. Lenz Dec 2017

Effects Of Ocean Warming And Acidification On Fertilization Success And Early Larval Development In The Green Sea Urchin, Lytechinus Variegatus, Brittney L. Lenz

HCNSO Student Theses and Dissertations

Climate change is predicted to affect the larval stages of many marine organisms. Ocean warming can reduce larval survival and hasten larval development, whereas ocean acidification can delay larval development. Ocean acidification is especially concerning for marine organisms that develop and grow calcified shells or skeletons in an environment undersaturated with calcium carbonate minerals. This study assessed the effects of ocean warming and acidification on the fertilization and larval development of the green sea urchin, Lytechinus variegatus, a tropical species common in Florida and the Caribbean. After spawning, gametes were fertilized and embryos/larvae were reared at: 1) 28°C and …

How Metamorphosis Is Different In Plethodontids: Larval Life History Perspectives On Life-Cycle Evolution, Christopher K. Beachy, Travis Ryan, Ronald M. Bonett Oct 2017

How Metamorphosis Is Different In Plethodontids: Larval Life History Perspectives On Life-Cycle Evolution, Christopher K. Beachy, Travis Ryan, Ronald M. Bonett

Scholarship and Professional Work - LAS

Plethodontid salamanders exhibit biphasic, larval form paedomorphic, and direct developing life cycles. This diversity of developmental strategies exceeds that of any other family of terrestrial vertebrate. Here we compare patterns of larval development among the three divergent lineages of biphasic plethodontids and other salamanders. We discuss how patterns of life-cycle evolution and larval ecology might have produced a wide array of larval life histories. Compared with many other salamanders, most larval plethodontids have relatively slow growth rates and sometimes exceptionally long larval periods (up to 60 mo). Recent phylogenetic analyses of life-cycle evolution indicate that ancestral plethodontids were likely direct …

Plant responses to the environment are shaped by external stimuli and internal signaling pathways. In both the model plant Arabidopsis thaliana (Arabidopsis) and crop species, circadian clock factors are critical for growth, flowering, and circadian rhythms. Outside of Arabidopsis, however, little is known about the molecular function of clock gene products. Therefore, we sought to compare the function of Brachypodium distachyon (Brachypodium) and Setaria viridis (Setaria) orthologs of EARLY FLOWERING 3, a key clock gene in Arabidopsis. To identify both cycling genes and putative ELF3 functional orthologs in Setaria, a …

Understanding And Optimizing Growth And Development Of California Yellowtail (Seriola Dorsalis) In Aquaculture Using Physiological Tools, Laura Schwebel

Theses

Physical fitness metrics were used to assess the health and development of California Yellowtail, Seriola dorsalis, in an aquaculture environment during two grow-out experiments. The first experiment sought to evaluate the effects of a common aquaculture deformity (an improperly inflated swim bladder) that has been hypothesized to impact energy allocation, growth, and development. Metrics including metabolic rate, critical swimming speed, feed conversion ratio, and growth rate, were monitored over a 32-week period in three groups of California Yellowtail: wild-caught (“wild”), healthy hatchery-reared (“inflated”), and hatchery-reared with uninflated swim bladders (“uninflated”). At the start of the grow-out period, wild fish …

Evidence Of Multidecadal Recruitment In The Ocean Quahog, Arctica Islandica In The Western Atlantic Ocean, Sara M. Pace

Master's Theses

Ocean quahogs (Arctica islandica) are the longest-lived, non-colonial animals known today, with a maximum life span exceeding 500 years. Limited information is available regarding recruitment, making the sustainable management of this valuable fishery a challenge. The objective of this research was to describe the age structure and growth rates for four populations of ocean quahogs from the mid-Atlantic stock to evaluate long-term recruitment trends. Clams were sectioned for age estimation to develop population age frequencies. Initial colonization began approximately 175-250 years ago depending upon site. All sites experienced an increase in recruitment beginning in the late 1800’s to …

Effects Of Engineered Carbon And Silver Nanoparticles On Plutella Xylostella Consumption, Growth, Pupation, Survival, And Fecundity, Taiaba Afrin

MSU Graduate Theses

Engineered nanoparticles (ENPs) have recently become common in consumer products, and will therefore be entering into both aquatic and terrestrial systems. However, the effects of ENPs on animals is not well characterized. For example, to date there has been no research on the effects of single walled carbon nanotubes (SWCNTs) and silver nanoparticles (AgNPs) (common ENPs) on insects. I examined the effects of pure SWCNTs and AgNPs on consumption, growth, food conversion ratio, pupation, survival, fecundity, and expression of CYP6BG1 using fourth instar of diamondback moth (DBM) larvae with the following concentrations: 8.64, 17.28, 34.56, 69.12 and 138.24 µg/ml SWCNTs; …

Coral Vs. Macroalgae: Relative Susceptibility To Sedimentation And Ocean Warming, Ashton J. Galarno Jul 2017

Coral Vs. Macroalgae: Relative Susceptibility To Sedimentation And Ocean Warming, Ashton J. Galarno

HCNSO Student Theses and Dissertations

Sedimentation and ocean warming are two major anthropogenic stressors that directly affect coral recruitment and recovery. Many coral-dominated reefs have undergone phase shifts becoming macroalgae-dominated because of the coral population’s inability to tolerate these increasing stressors. Predicting these phase shifts requires a determination of the relative susceptibility of coral and macroalgae to these stressors. The objective of this study was to quantitatively assess the synergistic effects of sedimentation and elevated temperature on the survival and growth of Montastraea cavernosa newly settled coral juveniles, and fragments of the macroalgae, Dictyota ciliolata. A crossed experimental design tested the two temperatures and …

Beyond Age And Stage: Consequences Of Individual Variation In Demographic Traits, Erin Elizabeth Feichtinger Jul 2017

Beyond Age And Stage: Consequences Of Individual Variation In Demographic Traits, Erin Elizabeth Feichtinger

USF Tampa Graduate Theses and Dissertations

Within natural populations, individuals vary in their propensity to grow, survive and produce offspring. Additionally, fates of individuals are often correlated and non-independent as a result of shared genes, rearing environment or both. Variation in demographic traits can change population dynamics over time. The effects of variation in individual growth rate on population growth rate, net reproductive rate and generation time are examined, along with quantifying the sources of variation in survival of a long-lived cooperatively breeding bird, the Florida Scrub-Jay (Aphelocoma coerulescens). I built a 2 stage population model with two growth phenotypes, fast and slow, and …

Comparing The Ecological Stoichiometry In Green And Brown Food Webs: A Review And Meta-Analysis Of Freshwater Food Webs, Michelle A. Evans-White, Halvor M. Halvorson Jun 2017

Comparing The Ecological Stoichiometry In Green And Brown Food Webs: A Review And Meta-Analysis Of Freshwater Food Webs, Michelle A. Evans-White, Halvor M. Halvorson

Faculty Publications

The framework of ecological stoichiometry was developed primarily within the context of “green” autotroph-based food webs. While stoichiometric principles also apply in “brown” detritus-based systems, these systems have been historically understudied and differ from green ones in several important aspects including carbon (C) quality and the nutrient [nitrogen (N) and phosphorus (P)] contents of food resources for consumers. In this paper, we review work over the last decade that has advanced the application of ecological stoichiometry from green to brown food webs, focusing on freshwater ecosystems. We first review three focal areas where green and brown food webs differ: (1) …

Growth And Poverty Traps: Examples From Literature, Danielle Chaloux May 2017

Growth And Poverty Traps: Examples From Literature, Danielle Chaloux

Honors Scholar Theses

The writings of Charles Dickens, Emile Zola, Knut Hamsun, and Laura Ingalls Wilder capture humanity on the page. The characters in the works of these authors are confronted by realistic or autobiographical situations and make choices based on history, personal preferences, societal pressures, and economic constraints, just as real-life individuals do. They can thus serve as data for illustrating the implications of economic models, specifically poverty traps. To do so, I will draw from Great Expectations (1861) by Charles Dickens, The Fat and the Thin (1873) by Emile Zola, Hunger (1890) by Knut Hamsun, and The First Four Years (1971) …

Coral-Excavating Sponge Cliona Delitrix: Current Trends Of Space Occupation On High Latitude Coral Reefs, Ari Halperin, Andia Chaves-Fonnegra, David S. Gilliam

Marine & Environmental Sciences Faculty Articles

The recent increase in abundance of coral-excavating sponges is a threat to the health of coral reefs. However, the distribution and growth of these sponges are poorly documented on high latitude reefs where corals live in marginal environmental conditions. In this study, we characterize the current trends of space occupation of Cliona delitrix on high latitude reefs (26°N) in southeast Florida. C. delitrix densities were significantly higher on the deepest habitat of this reef tract (the outer reef) in response to a higher availability of coral substratum. Sponge growth rates increased with depth, and in relation to presence of tunicates …

Intracellular Membrane Organization In Mycobacteria, Jennifer Hayashi Mar 2017

Intracellular Membrane Organization In Mycobacteria, Jennifer Hayashi

Doctoral Dissertations

Mycobacterium is a diverse genus of actinobacteria that includes the causative agents of human tuberculosis and leprosy. Mycobacteria are protected by their unique, multilaminar cell envelope, which grants them intrinsic resistance to environmental challenges such as antibiotics. This essential cellular structure is elongated at the polar ends of cells, but the regulation of cytosolic precursor synthesis and localized envelope synthesis remains unclear. Here, we present the PMf (plasma membrane free of cell wall components), a membrane domain distinct from the bulk plasma membrane of Mycobacterium smegmatis. Proteomic and lipidomic characterization demonstrate that the PMf contains lipidic substrates of cell …

Effects Of A Large-Scale Habitat Enhancement Project On Largemouth Bass Behavior, Feeding, And Growth In Grand Lake, Texas, Chance Kirkeeng Jan 2017

Effects Of A Large-Scale Habitat Enhancement Project On Largemouth Bass Behavior, Feeding, And Growth In Grand Lake, Texas, Chance Kirkeeng

Electronic Theses and Dissertations

The quality of habitat, or the environment suitable for an organism to survive and reproduce, is often described by the type of features present and the quantity and condition of such features. Habitats in many ecosystems are declining and the loss of important habitats likely affects the success of organisms reliant upon those features. Habitats in reservoir ecosystems are especially at risk because of aging processes that are degrading reservoir habitats at faster rates than habitats in other ecosystems. Habitat enhancement projects are one tool used to combat the effects of aging reservoirs but the benefits of these management actions …

Effects Of Wildfires On Rattlesnake (Crotalus Oreganus) Growth And Movement In Washington State, Joseph Chase Jan 2017

Effects Of Wildfires On Rattlesnake (Crotalus Oreganus) Growth And Movement In Washington State, Joseph Chase

All Master's Theses

Fire is a dominant force in the Pacific Northwest that shapes ecosystems and influences wildlife, yet little is known of its effects on local predators. Northern Pacific rattlesnakes (Crotalus oreganus) comprise an excellent model to investigate how fire may influence wildlife because they are important predators that contribute to controlling prey populations, but are also unable to readily escape from wildfires. We developed a novel technique to assess growth rates of rattlesnakes by using digital photography to analyze differences in widths of their rattle segments laid down over time. We compared growth rates of rattlesnakes in habitats that …
