This thesis is an investigation of the natural products deriving from marine
algae and cyanobacteria and has resulted in the discovery of eleven new secondary
metabolites. The structure elucidations of these new molecules were performed
using a...

Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species...
