  • Dunedin (2010)
    BIODIVERSITY: 2010 and beyond NEW ZEALAND ECOLOGICAL SOCIETY CONFERENCE 22–25 November 2010 University of Otago, Dunedin Programme and Abstracts http://www.nzes.org.nz/ Miss E. L. Hellaby Indigenous Grasslands Research Trust Welcome and conference overview Welcome to ‗Biodiversity: 2010 and beyond‘, the 2010 annual conference of the New Zealand Ecological Society. The theme of this year‘s conference recognises and celebrates 2010 as the United Nations International Year of Biodiversity. To acknowledge this, we present ten symposia examining a range of topics related to biodiversity. There are nine plenary speakers, from Canada, the United Kingdom, the USA, and New Zealand, and more than 90 contributed oral and poster presentations. The subjects covered are diverse and we are sure you will find many to interest you. We extend a particular welcome to the students presenting many papers throughout the conference, and to our overseas guests. In addition to discussing organisms and ecosystems, several symposia explicitly consider biodiversity in relation to human populations – cultural perspectives, production lands, and urban environments. Others examine aspects of managing and protecting biodiversity – assessment, prioritisation and reporting, and reintroduction and pest management. Two special forums are offered: a workshop as part of the ‗Cultural perspectives‘ symposium, and a discussion panel as part of the ‗Production lands‘ symposium. These meetings are described later in this Programme. A successful conference depends on voluntary efforts by a great many people. We particularly thank the organising team, symposium convenors, and field trip organisers. Many people have helped in other ways, most notably the student volunteers who will assist to make things run smoothly.

Cycles of Climate Fluctuation Scientists understand that Cycles of Climate Fluctuation are a natural and on‐going part of Earth’s Climate Systems. However, since the early 1970’s scientists have been concerned at the effect of increased greenhouse gases in the atmosphere resulting from Human activities. These increased greenhouse gases are raising temperatures and destabilising the Earth’s climate systems. They are changing the natural climate cycles. Natural Climate Cycles are an important part of the Earth’s systems that cause changes in the physical (abiotic) environment, and through these changes, impact on the biotic environment within ecosystems. These environmental changes may alter selection pressures that could result in changes to the distribution patterns of species. Allan Wilson Centre Post Doctoral Fellow Ceridwen Fraser has recently completed her PhD, which saw her spend three years unravelling a story of the impact of climate cycles that is hidden in the DNA of Southern Bull Kelp (Durvillaea antarctica). Using modern biotechnologies to analyse DNA from Bull Kelp samples collected from the coastline of New Zealand, Southern Chile and Sub‐Antarctic Islands, Ceridwen has discovered evidence that in the last ice age the sea ice was more extensive than previously thought, and that this has Fig 1.

How Antarctic terrestrial species might have survived these glaciations has been a topic of intense interest, yet many questions remain unanswered, particularly for Antarctica’s invertebrate fauna.

    ANU COLLEGE OF MEDICINE, BIOLOGY & ENVIRONMENT ________________________________________________________________________________________________________________________________ Dr Ceridwen Fraser The Fenner School of Environment and Society Australian National University Building No. 141, Canberra, ACT 2601, Australia [email protected] 23 March 2015 To Whom it May Concern: I would like to apply for an Antarctic Science Bursary to support field work on Deception Island with the Spanish Polar Programme in the coming summer season (2015-2016). The following pages comprise, in order: - Description of my current research project - Description of my proposed research project (to be supported by the Bursary) - Budget and budget justification - Emails from the Spanish Polar Programme regarding my participation - A brief curriculum vitae - A copy of my collecting permit for the Deception Island work The application form, with the relevant sections completed by my supervisor, is included separately. Please note: I received my PhD in December 2009, and am therefore just over five years post-PhD. I recently asked Prof David Walton how ‘early career’ is defined for these Antarctic Science Bursaries. He told me that there are no strict limits, and that I would probably be considered early career by the Board. Thank you in advance for considering my application. Yours Sincerely, Ceridwen Fraser CURRENT PROJECT Current Project: Volcanoes as safe-havens for Antarctic species during ice ages I currently have Australian Research Council (DECRA: Discovery Early Career Research Award) funding to research the role of volcanoes in maintaining biodiversity through past ice ages in Antarctica. Description of existing project: Antarctica was heavily glaciated at the peak of the last Ice Age (~18,000 years ago)1, yet biological evidence indicates that most Antarctic terrestrial species have existed on the continent for millions of years2-4.

Email: [email protected] Pleistocene glacial–interglacial cycles would have resulted in drastic changes in the structure of sub-Antarctic littoral ecosystems. Genetic data indicate that the large kelps that dominate intertidal and shallow subtidal sub-Antarctic shores today (such as Macrocystis pyrifera and Durvillaea antarctica) were extirpated from these high latitude regions by sea ice scour during glacial maxima. These macroalgae, and their associated faunal communities, were able to return to the sub-Antarctic islands during interglacial periods by drifting at sea in the path of the Antarctic Circumpolar Current. During glacial maxima, sub-Antarctic littoral communities would have been severely reduced, comprising mainly ice-scour hardy taxa such as small and/or seasonal macroalgae, and mobile molluscs.
