A journey southwards to the subantarctic islands

Wednesday 7th of December 2005, 05:20 PM (15 years ago)

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

A talk by Adrienne Markey. The flora of the sub-antarctic islands, and its affinities to the flora of New Zealand has always held the interest of botanists, starting from Joseph Dalton Hooker on the Antarctic voyages of the H.M. Discovery Ships Erebus and Terror (1839 1843), to recent research using molecular markers to track the dispersal and evolution of plants in these regions. So, with great boldness and audacity, I found myself able to also make a direct comparison of these regions. Yes, the origins and evolution of the Sub-Antarctic plants fascinate me, and it offered a chance to collect both Coprosma perpusilla ssp. subantarctica and Nertera depressa from their southernmost distributions and to complement current studies that I and fellow researchers had in progress. This talk will cover a week-long trip with Heritage Expeditions that Alex Fergus and I took part in earlier this year, and will show some of the glamorous megaphyllous herbs as well as a token seabird or two. 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. Followed by BSO End of year Dinner, 7 pm - see more details.

Ghosts of Indian Princes - 4th Annual Geoff Baylis Lecture

Wednesday 26th of October 2005, 05:10 PM (15 years ago)

Contact: Robyn Bridges | robyn.j.bridges@gmail.com | (03) 472 7330 / 021 235 8997

Assoc. Prof. Kevin S. Gould will present the 4th Annual Geoff Baylis Lecture with a talk entitled Ghosts of Indian Princes - The Remarkable Properties of Red Pigmented Plants. The eastern states of North America play host each year to one of natures most spectacular phenomena. From Maine to North Carolina a rich mural of reds, carmines, crimsons, scarlets, and purples accompanies the leaves of deciduous trees as they embark on the processes leading to winter dormancy. New Zealand, too, has its share of vermillion spread across all orders of plants from the liverworts to the angiosperms. Such displays have long been considered an extravagancy without a vital function. In contrast, recent research suggests that the red pigments anthocyanins can in some instances be critical for plant survival. Anthocyanins seem to empower plants to tolerate a diverse assortment of environmental stressors, including exposures to strong light, ultraviolet radiation, drought, cold, fungal infections, and even protection from herbivores. The pigments are, moreover, potent scavengers of free radicals, the reactive atoms and molecules that have the potential to destroy DNA, membranes, and proteins. Red-pigmented plants also hold the potential for the advancement of human health; the consumption of anthocyanin-rich foods is associated with a lower risk of non-infectious diseases, including coronary heart disease, osteoporosis, ischemic stroke, Alzheimers, and certain cancers. These remarkably versatile pigments are evidently natures Swiss army knife.

Leaving the white line: A journey in conserving the rainforests of the Adelbert Mountains, PNG

Wednesday 21st of September 2005, 05:20 PM (15 years ago)

Contact: Robyn Bridges | robyn.j.bridges@gmail.com | (03) 472 7330 / 021 235 8997

Talk by Matt Scott. The Adelbert Range in northern Papua New Guinea, boasts a remarkable biodiversity, hosting up to 57 mammalian species and some 336 avian species. Many of these species, like the Fire-Manned Bower bird, are found nowhere else in the world. However, there has been significant pressure from the government to log these virtually pristine forests as part of a large forestry concession. The Nature Conservancy (TNC) is using innovative solutions to help protect the landscape and biodiversity of this region. I will discuss the project, the people and my personal experience working in the Adelbert Range. 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.

Tunnel Beach

Saturday 23rd of July 2005, 09:00 AM (15 years ago)

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

Half-day visit to the dramatic coastal sandstone cliffs, caves, tunnels and arches just south of Dunedin. It's a short 20 min walk down to the mouth of the tunnel, where a stunning natural arch is still covered in a close mat of coastal turf plants, despite continued grazing and trampling. Look out for; tiny selliera (Selliera radicans), sea primrose (Samolus repens) and tiny button daisy (Leptinella dioica) and their low-growing companions. A hand lens and kneeling pad would be handy. Dress for the weather and wear shoes or boots with a good grip - the drop-offs are sheer! Queries to Allison Knight, 487 8265. Meet at the Botany Car Park for car pooling, or at the Tunnel Beach carpark 20 min later.

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

Led by John Barkla. NZs only inland saline lake, with water half as salty as sea water. Salt-tolerant herbs line the margins of the lake, which occupies a shallow depression in the schist landscape near Middlemarch. Surrounding grasslands and shrublands have not been grazed since 1991 and contain uncommon plants such as the endemic speargrass, Aciphylla subflabellata, while the rock tors harbour an undescribed native forget-me-not. There will be a species list we hope to add to. Its an easy walk, bring your lunch and be prepared for frost. Back mid - late afternoon. Contact John Barkla, 476 3686 (evenings).
