Microbial Stoichiometry And Homeostasis Of Nutrient Ratios In Fungi, Desiree Leach
Microbial Stoichiometry And Homeostasis Of Nutrient Ratios In Fungi, Desiree Leach
Honors Theses
Stoichiometry is the ratio of elements in a substance or microbial biomass. This paper investigates microbial stoichiometry and the responses of microbes to dissolved nutrient concentrations and ratios. The current work assesses both autrotrophic and heterotrophic responses to nutrient enrichment: autotrophic and heterotrophic states are defined mainly by ecosystem primary production and respiration. In ecosystems dominated by autotrophic microbes, nutrient enrichment can lead to increased biomass and biomass-specific rates of primary production. Heterotrophic ecosystems rely on subsides of organic carbon from outside the system. Their enrichment with N and/or P can accelerate microbial respiration rates and result in carbon losses …
Growth Rate Of Mugil Cephalus From Two Isolated Ponds In Huntington Beach State Park, South Carolina, Matthew Vincent
Growth Rate Of Mugil Cephalus From Two Isolated Ponds In Huntington Beach State Park, South Carolina, Matthew Vincent
Honors Theses
Measurement of growth of the euryhaline teleost Mugil cephalus is quite common in open ocean settings, but growth rates of M. cephalus in isolated areas is non-existent. Two isolated ponds in Huntington Beach State, Horry County, South Carolina were selected to study the growth rate of M. cephalus; Sandpiper Pond with virtual no hydrologic connection to the ocean and Jetty Pond with adequate hydrologic connection to the ocean were the sites of sample collection. Scales from M. cephalus in both ponds were collected then aged by two readers, where agreeing ages were kept in the dataset. A von Bertalanffy growth …
