Trip led by Mike Thorsen, DoC. Times to be confirmed. Akatore is a remnant of diverse coastal shrubland at the mouth of Akatore Creek 45 minutes south of Dunedin. Some special features of this site include the diversity of shrub species and threatened species such as Coprosma obconica, Olearia fragrantissima, and Carex littorosa with the possibility of our discovering other threatened species. We'll also visit the adjacent coast where the threatened cress Lepidium tenuicaule is present as well as Myosotis pygmaea.

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.

Seacliff Scenic Reserve comprises three discrete indigenous forest remnants near the Truby King Reserve. One of these, Guilds Hill, has a distinctive coastal forest element that includes the uncommon fragrant tree daisy, fierce lancewood and at least two species of mistletoe, one of which is hemi-parasitic on the other! The hill top provides a great view to the south and a lunch spot. Prior to its reservation the forest had a checkered history and suffered a partial forest collapse. A number of serious weedy lianes and shrubs have subsequently established and some grazing still occurs. Come along and give your views on management options. Leave Botany carpark at 9.30 am Sunday and return early to mid afternoon. Bring lunch and be prepared for untracked walking and muddy conditions.

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.

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.

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.
