The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Life history strategies of three species of Cystophora (Phaeophyta, Fucales) from a shallow subtidal community in South AustraliaHotchkiss, Sarah L. (Sarah Lynn) January 1999 (has links) (PDF)
Bibliography: p. 125-138. A number of life history traits were quantified for three species of Cystophora. The composition and dynamics of the community were monitored and related to temporal changes in the patterns of growth and reproduction of each species, and also to patterns of recruitment and early community development.

The uptake of arsenicals by the marine algae Isochrysis galbana and Dunaliella tertiolectaTsang, Angela Ka Yen January 1990 (has links)
Two marine algae, Isochrysis galbana and Dunaliella tertiolecta, were grown in the presence of arsenate, arsenite, monomethylarsonate (MMA), and dimethylarsinate (DMA). Cell growth was monitored by using in vivo fluorescence and cell density measurements. The effects of different levels of arsenicals on the arsenic uptake were examined using Hydride Generation Atomic Absorption (HGAA) Spectrometry and Graphite Furnace Atomic Absorption (GFAA) Spectrometry. The spin-echo ¹H NMR spectra of these algae are reported.
Significant arsenic uptake and incorporation occurred when both algae were subjected to elevated levels of arsenicals. I. galbana was most affected by arsenite at the range of concentrations tested (2 - 8 ppm). Total incorporation is also the highest in this medium. The alga seems to be able to adapt to high arsenate concentrations.
D. tertiolecta was most affected by elevated levels of arsenate (10.7 ppm). Water soluble extracts of algal cells grown in this medium contain at least four arsenicals which possibly include arsenate and arsenite.
Growth of both algae was not affected by DMA at the levels examined. Growth enhancement is observed in all MMA treated cultures. Arsenic speciation of the residual media showed that both algae can reduce arsenate to arsenite. / Science, Faculty of / Chemistry, Department of / Graduate
