More than the first page: A note regarding reading the newsletter: I am putting a lot of messages that used to be simply circulated by email into the newsletter. This is an attempt to avoid cluttering up your email boxes: so it is worthwhile reading not just the first page and the jokes but skimming the intermediate information.
Lots and lots of things happening as indicated last newsletter!!

Special Award
50th Anniversary Award for Professor George Knox
On Thursday 9th August, Bill Davison, Dave Schiel and Lyn de Groot attended a special presentation and afternoon tea at the Antarctic Centre to honour Emeritus Professor George Knox’s contribution to Antarctic Research (it being International Polar Year and the 50th anniversary of the NZ Antarctic programme).

Three generations of George’s family were present to hear the addresses by Clive Howard-Williams (Adjunct Professor of Biological Sciences and Gateway Antarctica) and Lou Sanson (CEO of Antarctica New Zealand). Sanson also referred to George’s founding contributions to ecology through his research and leadership roles in INTECOL and the Biomass programme. George was also presented with two paintings by Margaret Elliott*, one depicting “Tent City” at Windless Bight and the other an icy landscape. George’s second edition of the book “Biology of the Southern Oceans” has just been published and featured in the ceremony.

The afternoon was highly successful in that there was recognition of a scientist and his lifetime achievements but also that his family were included in the function.
*Artist in Residence and Gateway tutor in the UC postgraduate course.
[The 50th Anniversary Award would have been presented by the Minister at a formal ceremony in Wellington but George’s ill health prevented him attending.]

Erskine Visitors
Scott Wissinger (28 August - 16 November) is a Professor at Allegheny College, a small, but top-class liberal arts college in Pennsylvania. He has been chairperson of both the Biology and Environmental Science Departments at Allegheny, and has been heavily involved in the administration of the College, including chairing many institutional-level committees. As well as receiving many commendations for his teaching, Scott is also an accomplished researcher. He studies the community ecology of wetland and pond ecosystems. He has received a Presidential Young Investigator from the National Science Foundation and has previously visited New Zealand as a Fulbright Senior Scholar. During his visit he will be helping to teach the Freshwater Ecosystems course.
Ben Sheldon will be visiting the department as an Erskine Fellow from
1 September - 6 October. He is a Professor who heads the Edward Grey Institute for Field Ornithology in the Zoology Department at Oxford, and has published over 80 papers in this field (including many in Nature, PNAS, etc.). He is a leading researcher in Evolutionary Biology and Behavioural Ecology, and in addition to a departmental seminar (date to be advised) he will be running a workshop on this subject at the Edward Percival Field Station in Kaikoura from 7-8 September. The workshop is open to all academics and graduate students. Please contact Jim Briskie for more details.

Addition to the family
Just a quick note to let you know that our little surprise arrived this morning at 11:54. Corey Philippe Tremblay was 7 lb 7 at birth, which is not so little considering the size of the parents... Overall, Cara was simply amazing and everyone at Christchurch and Lincoln hospitals have been fantastic and made this day a memorable one.
All the best,
Cara and Louis

Safe in Peru: Michelle Greenwood
Michelle just gave us a quick call, she’s safe and well, which is great news.
They were having dinner on the deck of a restaurant and basically dived outside as the quake happened. One women was trapped in the building and another guy was injured and lost his fingers by a crushed beam (apparently the dog ate them the next morning). Anyway they are sleeping in tents in the desert for a second night before heading into Ica to try and get a bus north to Lima where they catch a plane to Equador.
She seems quite cheerful considering with her usual sense of humor about it all. Guess they are just going to have to be patient while transport infrastructure comes back on stream over the next few days. Interestingly we probably know more about what has happened than she does. She was still unsure about the level of damage in Ica, even though it is only 5 km down the road. Strange how the world media works…

"Scales of Biology"
Part VII of the thrilling multi-part story on Bacillus thuringiensis
How much cry toxin are we now exposed to from commercial transgenic organisms?
Cry toxin reaches concentrations as high as 115mg/g in corn seed (see previous newsletters). The yield of Cry protein ranges from 1.7 x 10e-7 – 7 x 10e-7mg/spore produced in a fermenter. Fermenter yields could be as much as 10-100 times the yield in nature. But using these conservative figures, the Cry load in soil at the B. thuringiensis detection limit is 1.7 x 10e-4 - 7 x 10e-4mg/g. Although Cry concentrations vary considerably among cultivars, even the commercial corn producing at the low end of the scale (MON810 at 0.19mg/g) would be the equivalent to eating between 150 and 520g/kg body weight of soil (Table). If we assume that the actual Cry load in soil is 10 times less, the average American would have to consume 1.5-6kg/kg body weight of soil a day to match the exposure from MON810. It is obvious from these figures that an average American would have to eat their body weight in soil each day to ingest the same quantities of Cry toxin that they may be exposed to from BT11 corn even using the most conservative assumptions.

and now for something completely different….
Sponges grow in the ocean. That just kills me. I wonder how much deeper the ocean would be if that didn't happen.
All those who believe in psychokinesis raise my hand.
The early bird gets the worm, but the second mouse gets the cheese.
I almost had a psychic girlfriend but she left me before we met.
OK, so what's the speed of dark?
