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 …
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 …
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 Low Concentrations Of Carbon Nanotubes On Growth And Gas Exchange In Arabidopsis Thaliana, Rajeeva Voleti
Effects Of Low Concentrations Of Carbon Nanotubes On Growth And Gas Exchange In Arabidopsis Thaliana, Rajeeva Voleti
MSU Graduate Theses
The effect of pure single-walled carbon nanotubes (SWCNTs) on plant growth and gas exchange was investigated in Arabidopsis thaliana. To date there has been no research on the effects of SWCNTs on whole plant physiology. A. thaliana seeds were directly grown in growth medium containing SWCNTs concentrations of 24.93micrograms/ml and 53.55 micrograms/ml. control plants were grown in media containing distilled water. I determined growth by measuring dry mass of plants. I determined gas exchange by measuring photosynthetic rates, stomatal conductance, transpiration rates, and water use efficiency. I also examined the following physiological mechanisms that would limit plant growth: ATP and …
Growth And Population Assessment Of Spotted Bass (Micropterus Punctulatus) In Beaver, Table Rock, And Bull Shoals Lakes, Northern Arkansas-Southern Missouri, Jeremy Troy Risley
Growth And Population Assessment Of Spotted Bass (Micropterus Punctulatus) In Beaver, Table Rock, And Bull Shoals Lakes, Northern Arkansas-Southern Missouri, Jeremy Troy Risley
MSU Graduate Theses
Little research has been conducted on spotted bass, Micropterus punctulatus, even though it is a popular recreational fish. Most previous research was on young-of-the-year fish and interactions among other species in reservoirs, with little research on adult spotted base in the Ozarks region or other regions of the United States. The objective of this study was to compare the growth and population characteristics of spotted bass within and among Beaver, Bull Shoals and Table Rock Lacks. Growth, abundance, and conditions within and among reservoirs were similar. However, spotted bass in Beaver Lake did not reach as great lengths as those …
