Effects Of Tissue Nitrogen And Media Nitrate On Trace Metal Uptake And Trophic Transfer By Ulva Spp., Sonya Meenakshi Sankaran
Effects Of Tissue Nitrogen And Media Nitrate On Trace Metal Uptake And Trophic Transfer By Ulva Spp., Sonya Meenakshi Sankaran
Master's Theses
A general survey of trace metal content in Ulva spp. (Linnaeus) around Moss Landing, California was carried out. The next objective was to evaluate whether tissue nitrogen or media nitrate affects metal uptake (As, Pb, Mn, Zn) by Ulva spp. under eutrophic conditions. Additionally, the role of metal burden in the invertebrate Idotea resecata as a function of metal content in its diet was examined. Mean trace metal concentrations in Ulva differed significantly among sites in Moss Landing, California. Laboratory measurements using samples from 15 sites along the central California coast revealed a significant positive correlation between Ulva spp. tissue …
