Wednesday 11th of October 2006, 05:20 PM (14 years ago)

Contact: Allison Knight | alli_knight@hotmail.com | 027 487 8265

A talk by Hugh Wilson, 5th Geoff Baylis Lecturer. Banks Peninsula is a unique part of NZ. It has suffered massive changes to its flora and fauna because of two waves of human settlement, Polynesian and European. Hugh will look at Banks Peninsula in pre-human times, at what happened as humans impacted on it, what it is like now and what it might be like in 100 years time. Hugh is guardian of more than 1000 hectares, 1%, of Banks Peninsula. He manages Hinewai Reserve under a policy of minimum interference and is documenting the reappearance of native vegetation. NOTE SPECIAL VENUE, Castle 1 Lecture Theatre, Otago University.

Co-evolution on the Galapagos Islands

Wednesday 27th of September 2006, 05:20 PM (14 years ago)

Contact: Allison Knight | alli_knight@hotmail.com | 027 487 8265

A talk by Drs Allison and John Knight. The Galapagos Islands rose steaming from the equatorial Pacific Ocean over the last 10 million years. Their sterile volcanic slopes were gradually populated by a limited range of plants and animals, mainly those that could cross the 1000 km gap from the nearest land. As Darwin found, the fascinating thing is that on each island a different combination of plants, pollinators, herbivores and frugivores has evolved together. Humans and grazing mammals arrived late on the scene; there are other parallels with New Zealand. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel.

Living in a high CO2 world: Impacts of global climate change on aquatic ecosystems

Thursday 14th of September 2006, 06:00 PM (14 years ago)

Contact: Trish Fleming | trish.fleming@botany.otago.ac.nz | (03) 479 7577

The John Smaillie Tennant Lecture 2006. A talk by Professor John Beardall, School of Biological Sciences, Monash University, Australia. This is a public lecture presented by the Division of Sciences and the Department of Botany. Professor Beardall began as a microbiologist, completing his BSc from Queen Elizabeth College at the University of London in 1973. He moved across town to University College for his PhD, where he developed a lifelong interest in photosynthetic organisms, doing some pioneering work on the pathways of carbon assimilation and adaptation to low light by microalgae. He graduated in 1976 and held postdoctoral appointments in Wales and Scotland before moving to Australia in 1982. He has broad interests ranging from the molecular mechanisms of photosynthesis and membrane transport to the primary productivity of oceans, but his interests in carbon have led him inexorably towards trying to understand the consequences, for aquatic systems, of the current crisis of anthropogenically-induced climate change. Note special venue: At the Union Street Lecture Theatre (corner of Union and Great King Streets). All BSO members, staff, students, and interested members of the general public are welcome to attend. Light refreshments will be served in the Botany Department Staff Room at 5:30 p.m.

A talk by Pascale Michel. This informal talk presents the ecological uniqueness of two main national parks in South America: Parque Nacional da Serra do Cipó (Minas Gerais, Brazil) and Parque Nacional Nahuel Huapi (San Carlos de Bariloche, Argentina). Serra de Cipó NP was created in 1984 to preserve a rich endemic flora, specific to dry high-altitude plateaux, and in particular the canela-de-ema (Vellozia pirestana) and a rare orchid (Constantia cipoensis). Nahuel Huapi NP comprises a large diversity of habitats expanding from Andean mountain beech forests to Patagonian steppes, and is home to humming birds and chinchillas.

A talk by Dr David Orlovich. Fungi are nature's recyclers. They form the connections between between plants and soil, algae and rocks, toxic wastes and the atmosphere, even life and death! In New Zealand, fungi support the beech forests of Fiordland, the high country tussock grasslands and our agricultural pastures through symbiotic mycorrhizal associations. I will give an overview of research on fungi in New Zealand, illustrate the beauty of many species found in New Zealand, and emphasise the importance of societies like the BSO in furthering research on New Zealand fungi. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open.

Field trip to Nenthorn, inland from Palmerston, with John Barkla

Saturday 29th of April 2006, 08:30 AM (14 years ago)

Contact: John Barkla | mjbarkla@xtra.co.nz | (03) 476 3686

The DOC reserve at Nenthorn/Macraes is best known as a site for rare skink conservation but there is also great botanical diversity, including over 25 threatened plants. It's a landscape of rolling tussockland dotted with lichen encrusted schist rock outcrops, shallow ephemeral wetlands, and the odd deep gully with shrubby remnants. We'll seek out some of the less familiar species and should encounter coral broom, wetland herbs such as Gratiola nana and Tetrachondra hamiltonii, and the rare grass Simplicia laxa. Leave Botany carpark at 8.30 am Saturday and return late afternoon. Bring lunch and be prepared for cool changeable weather conditions. This mileage for this trip is expected to be about 100 km. Students are encouraged to apply for the student subsidy for this trip.

Fish, frustules, fungi, flowers and foliage

Wednesday 15th of March 2006, 05:20 PM (15 years ago)

Contact: Allison Knight | alli_knight@hotmail.com | 027 487 8265

A talk by Jennifer Bannister. An investigation into the biota of an Early Miocene maar lake and its surrounding forest. About 20 million years ago a volcanic eruption near Middlemarch, formed a crater in the schist that filled with water. This type of lake is known as a maar. Sediment gradually built up on the lake floor, mainly the valves (frustules) of diatoms, where over time a finely varved diatomite formed. A forest grew up around the lake and leaves, flowers and fruits fell or were blown into the lake, sank on to the sediment and were preserved. We are trying to identify the leaves from their cuticles to build up a picture of the type of vegetation that grew there. We already have a pollen list although this is incomplete. At the Zoology Benham Building, 346 Great King Street, behind the Zoology car park by the Captain Cook Hotel. Use the main entrance of the Benham Building to get in and go to the Benham Seminar Room, Rm. 215, 2nd floor. Please be prompt as we have to hold the door open, and seats fill fast.
