Impacts Of Environmental Stressors On Mummichog (Fundulus Heteroclitus) Growth And The Gh-Igf1 Pathway Using A Laboratory Bioassay, Olena Kuntyj
Theses and Dissertations (Comprehensive)
Using a flow-through laboratory bioassay, experiments investigated the effects of limited feeding, increased temperature, ammonium chloride (NH4Cl), and 17α-ethinylestradiol (EE2) on juvenile mummichog (Fundulus heteroclitus) growth. Weight measurements were taken every three days as the apical growth endpoint. Gene expression was examined by qPCR for genes in the GH (growth hormone)-IGF1 (insulin-like growth factor 1) pathway, including gh, igf1, and their receptors (ghra, ghrb, igf1ra, igf1rb). In Experiment 1, juvenile mummichog were exposed to excess or limited feed for 21 days. The limited-fed mummichog weighed less, were …
The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro
The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro
All NMU Master's Theses
Burbot (Lota lota) are native fish in Lake Superior and typically spawn during the winter under the ice or by migrating up rivers. The early life history of larval burbot, where they dispurse, how fast they develop, and what their survival rates have not been extensively studied. Asynchronous hatching is a strategy used by other cod species as a bet-hedging strategy to ensure that some larvae are hatched in more advantageous conditions in a varying environment. Asynchronous hatching has been documented in burbot, but the extent of the period and the impacts that asynchrony has on the development of …

The Energy Requirement for Biosynthesis Plays an Important Role in an Organism's Life History, as It Determines Growth Rate, and Tradeoffs with the Investment in Somatic Maintenance. This Energetic Trait is Different between Painted Lady (Vanessa Cardui) and Turkestan Cockroach (Blatta Lateralis) Due to the Different Life Histories. Butterfly Caterpillars (Holometabolous) Grow 30-Fold Faster, and the Energy Cost of Biosynthesis is 20 Times Cheaper, Compared to Cockroach Nymphs (Hemimetabolous). We Hypothesize that Physiologically the Difference in the Energy Cost is Partially Attributed to the Differences in Protein Retention and Turnover Rate: Species with Higher Energy Cost May Have a Lower …
Largemouth Bass In The Upper Mississippi River: An Evaluation Of Management Strategies And Understanding Potential Factors Influencing Dynamic Rate Functions, Kylie Beth Sterling
Largemouth Bass In The Upper Mississippi River: An Evaluation Of Management Strategies And Understanding Potential Factors Influencing Dynamic Rate Functions, Kylie Beth Sterling
MSU Graduate Theses
The Upper Mississippi River (UMR) supports ecologically and economically important commercial and recreational fisheries. One recreational fishery in the UMR is the Largemouth Bass fishery. Recreational fisheries can be effectively managed using information on population dynamics, though little is known about Largemouth Bass population dynamics in large river ecosystems. Therefore, the objectives of this study were to 1) evaluate recruitment, growth, and mortality of three Largemouth Bass populations in the UMR, specifically within Pools 4, 8, and 13, and 2) to use those estimates of recruitment, growth and mortality to inform exploitation models to evaluate best management practices for each …
Corbicula Fluminea Effects On Survival, Growth, And Drift Of Juvenile Lampsilis Siliquoidea In Laboratory Exposures, Allison Nicole Sieja
Corbicula Fluminea Effects On Survival, Growth, And Drift Of Juvenile Lampsilis Siliquoidea In Laboratory Exposures, Allison Nicole Sieja
MSU Graduate Theses
The Asian clam, Corbicula fluminea, is an invasive species that is abundant and often co-occurs with native freshwater mussels. Corbicula is widely suspected of having negative effects on native mussels, but few studies have empirically tested this hypothesis. I used laboratory experiments to evaluate how adult Corbicula affected the survivorship, growth, and drift of juvenile Lampsilis siliquoidea. Survival and growth of newly metamorphosed mussels were tested in downwelling flow-through chambers with glass-bead substrate. Treatments were control (no clams), small adult clams, or large adult clams. After 28 days, large clams slightly but significantly reduced the number of juveniles …
Genes Related To Redox And Cell Curvature Facilitate Interactions Between Caulobacter Strains And Arabidopsis, Louis Berrios, Bert Ely
Genes Related To Redox And Cell Curvature Facilitate Interactions Between Caulobacter Strains And Arabidopsis, Louis Berrios, Bert Ely
Faculty Publications
Bacteria play an integral role in shaping plant growth and development. However, the genetic factors that facilitate plant-bacteria interactions remain largely unknown. Here, we demonstrated the importance of two bacterial genetic factors that facilitate the interactions between plant-growth-promoting (PGP) bacteria in the genus Caulobacter and the host plant Arabidopsis. Using homologous recombination, we disrupted the cytochrome ubiquinol oxidase (cyo) operon in both C. vibrioides CB13 and C. segnis TK0059 by knocking out the expression of cyoB (critical subunit of the cyo operon) and showed that the mutant strains were unable to enhance the growth of …
Pismo Clams (Tivela Stultorum) In Califorina: Population Status, Habitat Associations, Reproduction, And Growth, Alexandria R. Marquardt
Pismo Clams (Tivela Stultorum) In Califorina: Population Status, Habitat Associations, Reproduction, And Growth, Alexandria R. Marquardt
Master's Theses
Marine shellfish play a vital role in intertidal ecosystems and coastal communities, but many of these fisheries are small-scale and lack the necessary monitoring to ensure long-term sustainability. Effective management often requires information on key demographic parameters, such as population status, reproduction and growth. Pismo clams (Tivela stultorum) are a culturally important and iconic species in California, which supported a thriving commercial and recreational fishery throughout much of the 1900’s. However, Pismo clam populations have declined statewide in recent decades and are attributed to human harvest and predation by California sea otters (Enhydra lutris); However, no …
Exposure To Exogenous Egg Cortisol Does Not Rescue Juvenile Chinook Salmon Body Size, Condition, Or Survival From The Effects Of Elevated Water Temperatures, Theresa R. Warriner, Christina A.D. Semeniuk, Trevor E. Pitcher, Oliver P. Love
Exposure To Exogenous Egg Cortisol Does Not Rescue Juvenile Chinook Salmon Body Size, Condition, Or Survival From The Effects Of Elevated Water Temperatures, Theresa R. Warriner, Christina A.D. Semeniuk, Trevor E. Pitcher, Oliver P. Love
Great Lakes Institute for Environmental Research Publications
Climate change is leading to altered temperature regimes which are impacting aquatic life, particularly for ectothermic fish. The impacts of environmental stress can be translated across generations through maternally derived glucocorticoids, leading to altered offspring phenotypes. Although these maternal stress effects are often considered negative, recent studies suggest this maternal stress signal may prepare offspring for a similarly stressful environment (environmental match). We applied the environmental match hypothesis to examine whether a prenatal stress signal can dampen the effects of elevated water temperatures on body size, condition, and survival during early development in Chinook salmon Oncorhynchus tshawytscha from Lake Ontario, …
Dam Effects On Freshwater Mussel Growth And Recruitment In A Midwestern Stream, Taylor Lyndon Fagin
Dam Effects On Freshwater Mussel Growth And Recruitment In A Midwestern Stream, Taylor Lyndon Fagin
Masters Theses
There have been many studies that examine the negative impact of dams on freshwater mussel populations. However, recent studies suggest that some dams may create more suitable growing conditions immediately below some dams. This study’s main objectives were to 1) document where faster growth of mussels is found in relation to the Charleston Dam, 2) determine if sites with faster growth have higher recruitment and 3) investigate which water quality variable(s) could be correlated with faster growth. Live Corbicula sp. were set in cages in multiple sites at varying distances from the dam and shells of two native mussel species …
Pre-Juvenile Naked Goby (Gobiosoma Bosc) Age And Growth, Annamaria Deitz, Juliana Harding
Pre-Juvenile Naked Goby (Gobiosoma Bosc) Age And Growth, Annamaria Deitz, Juliana Harding
Honors Theses
Due to the abundance of larval naked gobies, Gobiosoma bosc, within the estuarine ichthyoplankton, it is important to understand their age and growth. Naked gobies are a largely distributed, both geographically and within an estuary, small, benthic fish species. There are 3 pairs of otoliths, calcium carbonate structures within the ear canal, that detect vibrations and record the age of the fish, both daily and annually. Using laboratory-reared gobies of a known age (Tremont et al. 2015), daily signatures on the sagittal otoliths were first validated to be daily, then a growth curve for the wild caught larvae was …
Growth And Toxicity Of Geographically-Distinct Isolates Of The Fish-Killing Phytoflagellate, Heterosigma Akashiwo, Veerta Singh
Growth And Toxicity Of Geographically-Distinct Isolates Of The Fish-Killing Phytoflagellate, Heterosigma Akashiwo, Veerta Singh
Electronic Thesis and Dissertation Repository
Harmful Algal Blooms (HABs)—an accumulation of toxic phytoplankton—often result from environmental changes reflecting the increasing global human footprint and climate change. One HAB species drawing attention is Heterosigma akashiwo, a fish-killing flagellate that can cause extensive fish loss or be benign, depending on location or environmental conditions. Here, I investigate if this difference in toxicity is regulated by environmental conditions or differences in cellular physiology. Six strains were examined. Three originate from the Salish Sea, where fish-kills are common, and three from Japan, where blooms of Heterosigma are common but fish-kills are rare. By measuring growth and toxicity of cells …
Detrital Nutrient Content And Leaf Species Differenitally Affect Growth And Nutritional Regulation Of Detritivores, Halvor M. Halvorson, Chris L. Fuller, Sally A. Entrekin, J. Thad Scott, Michelle A. Evans-White
Detrital Nutrient Content And Leaf Species Differenitally Affect Growth And Nutritional Regulation Of Detritivores, Halvor M. Halvorson, Chris L. Fuller, Sally A. Entrekin, J. Thad Scott, Michelle A. Evans-White
Faculty Publications
© 2018 The Authors Resource nutrient content and identity are common bottom–up controls on organismal growth and nutritional regulation. One framework to study these factors, ecological stoichiometry theory, predicts that elevated resource nitrogen (N) and phosphorus (P) contents enhance organism growth by alleviating constraints on N and P acquisition. However, the regulatory mechanisms underlying this response – including whether responses depend on resource identity – remain poorly understood. In this study, we tested roles of detrital N and P contents and identity (leaf species) in constraining growth of aquatic invertebrate detritivores. We synthesized results from seven detritivore species fed wide …
Phenotypic Integration Of Behavioural And Physiological Traits Is Related To Variation In Growth Among Stocks Of Chinook Salmon, Mitchel G.E. Dender, Pauline M. Capelle, Oliver P. Love, Daniel D. Heath, Christina A. Semeniuk
Phenotypic Integration Of Behavioural And Physiological Traits Is Related To Variation In Growth Among Stocks Of Chinook Salmon, Mitchel G.E. Dender, Pauline M. Capelle, Oliver P. Love, Daniel D. Heath, Christina A. Semeniuk
Biological Sciences Publications
The selection for a single organismal trait like growth in breeding programs of farmed aquaculture species can counter-intuitively lead to lowered harvestable biomass. We outbred a domesticated aquaculture stock of Chinook salmon (Oncorhynchus tshawytscha) with 7 wild stocks from British Columbia, Canada. We then examined how functionally related traits underlying energy management - diel variation in cortisol; foraging, social, and movement behaviours - predicted stock-level variation in growth during the freshwater life history stage, a performance metric under aquaculture selection. Outbreeding generated significant variation in diel cortisol secretion and behaviours across stocks, and these traits covaried, suggesting tight integration despite …

To address large-scale questions in evolutionary biology, the compilation of data from a variety of sources is often required. This is a major challenge in the development of databases in organismal biology. Here, we describe the procedure we used to reconstruct the phylogeny of the 474 species represented in HormoneBase, including fish, amphibians, mammals, birds, and reptiles. We also provide the methodology used to compile vertebrate environmental, life history, and metabolic rate data for use in conjunction with the HormoneBase database to test hypotheses of the evolution of steroid hormone traits. We then report a series of analyses using these …
Increasing Alligator Snapping Turtle Head-Starting Success Through Housing Enrichment And Inoculation Of Hatchlings With Digestive Microbiota, Kristen Erin Sardina
Increasing Alligator Snapping Turtle Head-Starting Success Through Housing Enrichment And Inoculation Of Hatchlings With Digestive Microbiota, Kristen Erin Sardina
MSU Graduate Theses
Due to historic overharvest and habitat degradation, the alligator snapping turtle (Macrochelys temminckii) has experienced population declines throughout its range. Tishomingo National Fish Hatchery in southern Oklahoma began a captive head-start program for this species in 2000 and has since released over 1,400 turtles in the region. However, there has been a recurring trend of turtles growing faster after release than while in captivity. My research sought to investigate this pattern by determining: 1) the influence of housing enrichment and housing density on juvenile growth rates and stress in indoor enclosures, and 2) the effects of supplementing hatchlings …
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
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 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; …
Effects Of Wildfires On Rattlesnake (Crotalus Oreganus) Growth And Movement In Washington State, Joseph Chase
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 …
Birth Mass Is The Key To Understanding The Negative Correlation Between Lifespan And Body Size In Dogs, Rong Fan, Gayla R. Olbricht, Xavior Baker, Chen Hou
Birth Mass Is The Key To Understanding The Negative Correlation Between Lifespan And Body Size In Dogs, Rong Fan, Gayla R. Olbricht, Xavior Baker, Chen Hou
Mathematics and Statistics Faculty Research & Creative Works
Larger dog breeds live shorter than the smaller ones, opposite of the mass-lifespan relationship observed across mammalian species. Here we use data from 90 dog breeds and a theoretical model based on the first principles of energy conservation and life history tradeoffs to explain the negative correlation between longevity and body size in dogs. We found that the birth/adult mass ratio of dogs scales negatively with adult size, which is different than the weak interspecific scaling in mammals. Using the model, we show that this ratio, as an index of energy required for growth, is the key to understanding why …

Trophic Ecology And Habitat Use Of Atlantic Tarpon (Megalops Atlanticus ), Benjamin Neal Kurth
USF Tampa Graduate Theses and Dissertations
Fish can have complex life histories and use multiple habitats and resources throughout their life span. Consequently, their life histories are often poorly understood. The Atlantic Tarpon, Megalops atlanticus, is a large, typically migratory, elopomorph fish that is both ecologically and economically important. Atlantic Tarpon are under threat due to regional exploitation, loss of natal and juvenile habitat, poor water management, and offshore impacts. In addition, little is known about its lifelong habitat and resource use. In Chapter 1, I used stable isotope analysis of eye lens δ13C and δ15N values to explore patterns in …

Effects Of Parasitism And Mite Control Methods On European Starling Development, Aderinsola Oluwasikemi Odetunde
Theses and Dissertations
Certain developmental stressors can lead to developmental trade-offs in young organisms. Hematophagous ectoparasites are a common stressor experienced by European starlings, and we wished to explore what aspects of an ectoparasite infestation drove trade-offs. The first part of this study was to test the hypothesis that blood loss was the sole mediator of trade-offs due to hematophagous ectoparasite infestation. We used nestlings that were exposed to mites in the nests, nestlings in mite-reduced nests experiencing supplementary blood loss, and nestlings in mite reduced nests with no supplementary blood loss. We also used a new heat treatment to reduce mites in …

Evaluating Foraging Habits, And Estimating Prey Consumption, And Growth Of Brook Trout In A Coolwater Michigan Stream, Graeme R. Zaparzynski
Masters Theses
Brook trout (Salvelinus fontinalis) are a cold water ectotherm whose native distribution includes most of eastern Canada, the upper Midwestern United States, and the eastern and mid- Atlantic United States as far south as Georgia. The native range of brook trout in the United States has been reduced as a result of interspecific interactions with introduced species, and anthropogenic land use changes that drive water temperature changes in many of their native watersheds. Anthropogenic land-use changes tend to increase thermal regimes of aquatic systems, affecting brook trout physiology and limiting them to colder, headwater reaches. The threat of …

Comparison Of Commercial Gecko Food On Growth Of Rhacodactylus Geckos, Kaitlin Leigh Richard
Honors Projects
Available food sources can provide a different effect on the growth rates of Rhacodactylus auriculatus. In this study three food sources were compared, Repashy MRP, Pangea super foods, and GeckoPro New Caledonian blend. These are composed of similar nutrients but tend to have some points where they vary. Thirty-six gargoyle geckos were put through a trial over a 14 week period to determine which commercially available food source provides the best nutrients for growth, as measured by weight gain. Three groups of twelve were chosen based on a variety of ages and sizes to be given three different foods …

Thermal performance curves are keys components of population ecology. We performed this study to determine the effects of aphids on duckweed age-structured models across temperature. Results show a depression in birth rates and maturation of rates of duckweed in the presence of aphids. Regression analysis shows that this depression in maturation and birth is directly proportional to aphid growth rates across temperatures. This hints of the idea of modeling duckweed and aphid growth via nested thermal performance curves.

Papers in Herpetology
The state of Florida, USA, has more introduced herpetofauna than any other governmental region on Earth. Four species of nonnative crocodilians have been introduced to Florida (all since 1960), one of which is established. Between 2000–2014 we field-collected three nonnative crocodilians in Miami-Dade County, Florida, and one in Hendry County, Florida. We used DNA barcoding and molecular phylogenetics to determine species identification and native range origin. Also, we described diet, movement, and growth for one crocodile. Our molecular analyses illustrated that two of the crocodiles we collected are most closely related to Nile Crocodiles (Crocodylus niloticus) from South Africa, suggesting …

Turkish Journal of Biology
Increased fragility of long bones and delay in fracture healing in adults as well as skeletal development disorders in children are thought to be associated with endochondral ossification problems. The extracellular matrix (ECM) of cartilage is absorbed during endochondral ossification. During the recovery process from damage, chondrocytes undergo hypertrophy and increase their cell volume; on the other hand, it is also necessary to digest the ECM elements around the cells. Recent research on the proteolytic enzymes in ECM assumed to be responsible for the digestion is connected to proteinases digesting type II collagen and aggrecan. ADAMTS1, 4, and 5 are …

An Investigation Of Juvenile Alewife (Alosa Pseudoharengus) Habitat Use And Growth Using Natural Markers, Gregory Norman Labonte Ms
All Student Scholarship
This research attempts to connect patterns in growth and migration of an anadromous species. The goal of this research was to understand habitat movements and growth of juvenile alewives (Alosa pseudoharengus) in the Penobscot Estuary and Bay through the use of otolith microchemistry, otolith growth increments, and a laboratory stable isotope turnover study. Understanding the connection between growth and movement of juvenile alewives may lead to more accurate and sophisticated conservation and restoration methods for anadromous species.
