As part of our new Discovery Project investigating the impacts of past conditions on growth responses to elevated CO2, we are delighted to announce two new PhD positions, one based here in Hobart and one based at the University of New South Wales in Sydney. More details are available here and here.
We are delighted to have received TWO new Australian Research Council grants to further our research. We received an ARC Discovery Project grant to continue work in TasFACE2, specifically to investigate how PAST conditions influence CURRENT responses to elevated CO2. This work will be done with our collaborators Dr Martin De Kauwe, an ecological modeller from the University of New South Wales, and Prof. Kiona Ogle, an expert in stochastic modelling from Northern Arizona University.
The second grant is a very large infrastructure grant that we have received with many colleagues from across southeastern Australia, including from the Australian National University, University of New South Wales, University of Canberra and La Trobe University. This infrastructure grant will be used to install an array of climatic sensors and experimental manipulations across the mountain areas of Australia, including in Tasmania. Very exciting is the news that we will be installing an eddy-covariance flux tower at our site at Silver Plains.
Mark recently attended an international workshop in Copenhagen, where representatives of all eleven Warming and Removal in Mountains (WaRM) experiments met for the first time. This workshop, held at the Centre for Macroecology, Evolution and Climate (CMEC) at the University of Copenhagen and hosted by Nate Sanders and Aimee Classen, identified areas for collaboration and planned joint analyses for publication. This was an extremely productive workshop and members of the group, including the Tasmanian ones, are working together already on publications and joint analyses.

It is time to announce the birth of a new free air carbon dioxide enrichment (FACE) experiment. There are only a handful of these in the world and we are pleased to announce that TasFACE2 – the Tasmanian watering-FACE experiment – is now operational. This has been an enormous amount of effort (I keep forgetting how difficult it is setting up a whole new manipulative field experiment – no matter how many times I do it…) but we are sure the rewards will flow now. For full details of TasFACE2 please read here…

Well, it is teaching in full-swing at the moment so Mark is busy with second and third year plant science classes. Meagan is setting up the new ryegrass-watering FACE experiment. Rose has been sorting data from elevated carbon dioxide experiments from across the world for a new data synthesis. PhD student Adam McKiernan is in the final throes of completing his PhD thesis, which is due to be submitted next week! So it’s all go around here after a hectic summer of field work setting up the Warming-Species Removal experiments.
This summer we established a completely new experiment, the Warming-Species Removal experiment. You can read all about the experiment on our “Experiments” page. Below are some photos of the set-up and sites.
