  • Establishment and Persistence of Dense Stands of the Introduced Kelp Undaria Pinnatifida"
    "Establishment and persistence of dense stands of the introduced kelp Undaria pinnatifida" by Joseph Peter Valentine BSc(Hons), University of Tasmania Submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy University of Tasmania (April, 2003) II Statement of Originality This thesis contains no material that has been accepted for a degree or diploma by the University or any other institution. To the best of my knowledge and belief, this thesis contains no material previously published or written by another person, except where due acknowledgement is made in the text. Joseph Peter Valentine Statement of Authority of Access This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968. Joseph Peter Valentine DI Acknowledgements To begin I would like to thank my supervisor, Craig Johnson for his encouragement and support over the duration of the project. Your efforts to secure funds made this work possible and for that I am very grateful. Your help and advice on experimental design and analysis was also appreciated, as was your understanding during some challenging times. An intensive diving project such as this one cannot be completed successfully (and safely) without a reliable diving buddy. This work could not have been conducted without the help of my fellow PhD student and friend Hugh Pederson. Hugh's assistance and advice above and below the water, particularly on all things mechanical was invaluable. I also appreciate Hugh's understanding in accommodating field schedules to meet the needs of both of our projects. It was not all hard work though- a tough day of Undaria surveying around Maria Island was often rounded out by fine cuisine, with 'Peanut butter chicken' a favourite.

This area is home to approximately 200 different species of macroalgae, representing the three major phyla of the green algae (Chlorophyta), brown algae (Ochrophyta) and the red algae (Rhodophyta), respectively. Over almost 50 years, the species of macroalgae associated and occurring within this area have resulted in the identification of a number of different types of secondary metabolites including terpenoids, sterols/steroids, phenolic acids, phenols, lipids/polyenes, pheromones, xanthophylls and phloroglucinols. Many of these compounds have subsequently displayed a variety of bioactivities. A systematic description of the compound classes and their associated bioactivities from marine macroalgae found within this region is presented.

  • Habitat-Forming Intertidal Algae Across Wave-Exposures
    HABITAT-FORMING INTERTIDAL ALGAE ACROSS WAVE­ EXPOSURES: AN EXPERIMENTAL EVALUATION OF PLANT AND HERBIVORE INTERACTIONS A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at the University of Canterbury ,New Zealand By David Ian Taylor UNIVERSITY OF CANTERBURY 2002 Abstract Ecological factors influencing the distribution, survival and growth across wave exposures of different life stages of some intertidal habitat-forming fucoid algae in southern New Zealand and Oregon were examined. Transect and quadrat sampling in southern New Zealand showed changes in patterns of habitat-forming intertidal algae across wave-exposures. Biomass and species richness across exposures varied greatly and was concentrated in the lower tidal zone. On wave-exposed platforms lower tidal zone biomass was often dominated by the bull kelp Durvillaea antarctica, mussels Perna canaliculus or suites of red algae (Gigartina species). Biomass in the lower tidal zones at moderately exposed platforms was dominated by perennial brown algae like Cystophora torulosa, C. scalaris and was dominated by the fucoid alga Hormosira banksii and the blue mussel Mytilus galloprovincialis at sheltered sites. Invertebrate herbivore abundance and biomass were similar across exposures but the greatest species richness was found in the upper tidal zones. Predator abundance was greatest at sheltered and exposed sites that were dominated by filter-feeder habitats. Settlement experiments compared the relative ability of Hormosira banksii, Cystophora torulosa and Durvillaea antarctica, to remain attached when exposed to a low energy wave after post-settlement attachment times of 1, 6 and 12 hours. Results showed the exposed shore species D. antarctica had better attachment capabilities than C.

  • Beautiful Browns
    stunningabout this guide | about seaweeds | species pages | icons | glossary seaweedsbeautiful brownsa guide to the large brown seaweeds of New Zealand Version 1, 2016 Kate Neill Wendy Nelson with Michelle Kelly & Blayne Herr 1 about this guide | about seaweeds | species pages | icons | glossary about this guide Seaweeds or marine macroalgae occur around the world and are found from the high shore to depths of around 200 m in some places. They are the marine equivalent of land plants and they vary in size from small filament- like species to huge kelps. Large brown algae are common and obvious on most parts of New Zealand’s coastline and we hope this guide will help you identify them in the field. This first part of STUNNING SEAWEEDS is a fully illustrated working e-guide to the most commonly encountered large seaweeds, the BEAUTIFUL BROWNS. It is designed for New Zealanders like you who live near the sea, dive and snorkel, explore our coasts, make a living from it, and for those who educate and are charged with kaitiakitanga, conservation and management of our marine realm. It is one in a series of e-guides on New Zealand marine seaweeds and invertebrates that NIWA’s Coasts and Oceans group is presently developing. The e-guide starts with a simple introduction to seaweeds, followed by a morphology (shape) index, species index, detailed individual species pages, and finally, icon explanations and a glossary of terms. As new species are discovered and described, new species pages will be added and an updated version of this e-guide will be made available.
