Here are links to a video of a presentation that I gave at the Eco Antarctica Symposium - "INTERDISCIPLINARY PATHWAYS TO ANTARCTICA" on 9 August 2016 at the Leon Kane-Maguire Theatre, Innovation Campus, University of Wollongong.

 

The video is available in HD from my multimedia page

and also on Youtube, where you can find some of my other media presentations.

I recently returned from this year’s ICPR conference held in Maastricht in the Netherlands. The photosynthesis congress is held every four years and hosts researchers involved in all aspects of photosynthesis research. In what was the largest poster room I have ever seen, I was lucky enough to present a poster on understanding the regulation of photosynthesis during sun-flecks. I was also lucky enough to present two talks on solar induced fluorescence (SIF) at both the main conference and a satellite meeting held in Essex the week prior.

Many ecological questions require information on species' optima in relation to environmental gradients. These attributes can be important in determining which species will coexistence and how this may vary with climate changes. However, existing methods do not quantify the uncertainty in the attributes or they rely on assumptions about the shape of species' responses to the environmental gradient. To remedy this, Mick Ashcroft and the team recently developed a model to quantify the uncertainty in the attributes of species response curves and allow them to be tested for differences without making assumptions about the shape of the responses.

The 3 minute thesis competition is where students have to explain their project in 3 minutes with just one slide and no props.  It is a national competition and starts off with Faculty heats. Rhys Wyber's very short talk was called "LIFTing photosynthesis to new heights" and he won against stiff competition across the SMAH Faculty. We look forward to similar success in the university finals.  Go Rhys!

On Wednesday we celebrated four graduands.  Dr Mel Waterman and Dr Johanna Turnbull were awarded their PhDs. Professor Bob Furbank became Dr Dr Bob. He was awarded an Honorary Doctor of Science.  In his inspiring graduation speech he told the graduands how important it was to try and work in an area which you love. I certainly agree with that sentiment.  He also talked about the important part played by mentors, peers and of course serendipity. 

We had a very interesting meeting yesterday to discuss connections between the work Rhys Wyber and Barry are doing at the leaf level, Zbynek at the canopy level and satellite measurements. The question is how can we bridge the gap between these scales to help inform measurements of global productivity and carbon dioxide in the atmosphere.  

It has been a busy month. PhD Student Beat Keller visited us from Germany bringing the new Forschungszentrum Jülich LIFT for Rhys to try out. Then we got new stronger light emitting diodes (LEDs) for our instrument so Rhys and Beat installed these. We can know measure fluoresence over bigger areas of canopy.  So Rhys is pretty happy. You can see them working in the dark here.

Just over 10 years ago, Sharon and I got within 12 nautical miles of Mawson station when we came to Antarctica to collect moss samples as part of my PhD project. At the time the sea ice was too thick and we had to turn back, but we already had enough samples from Casey and Davis so it wasn’t a big deal.

Ex Lab member Dr Laurence Clarke has been on the Kerguelen (k)-Axis Marine Science Voyage aboard the Aurora Australis for about 6 weeks now. He was collecting samples to barcode marine life and wrote a guest blog about his research here.

There is also a news feature on the Australian Antarctic Division web site.

Recent PhD graduate Dr Jessica Bramley-Alves has written an article for the Guardian Higher Education section Why I love my PhD.  Like Laurence she worked in Antarctica. She writes “My PhD takes me to one of the last truly wild places on earth. I thought a PhD wouldn’t suit me or I’d find the lab work tedious. But it’s actually been a great adventure”
