What's On at UWA

R is a free and extremely powerful language and software environment for statistical computing, data analysis, and graphics. The course is designed for those who have no experience with R, but have a basic understanding of statistics. The course will include: Introduction to R: How to install R on your computer; basic R commands, how to use and understand the R help pages. Data: Reading in data and data manipulation; summarising data; basic statistical analysis and fitting linear models. Graphics and output: Basic plotting commands and how to customise your plots; how to export your plots and output in a user-friendly format. Functions: Writing simple functions and flow control structures.

Heritability is often used by plant breeders and geneticists as a measure of a trial’s precision, or the precision of a series of trials. For computing its main use is the response to selection.

Most formulas proposed for calculating heritability implicitly assume balanced data and independent genotypic effects. While both of these assumptions are often violated in plant breeding trials, equations assuming balanced data are still in common usage.

This talk reviews various approaches to assessing heritability and derived quantities for unbalanced plant breeding trial data. Furthermore, Professor Piepho will also discuss the related problem of assessing predictive accuracy in genomic selection.

The low molecular weight thiol antioxidant, reduced glutathione (GSH) is a multifunctional metabolite in plants. GSH is an important redox gatekeeper that maintains redox homeostasis. It also participates in oxidative signalling pathways that regulate gene expression and determine the outcome of plant responses to stress. GSH is synthesised in chloroplasts, from thence is transported to all the compartments of the cell including the nucleus. Mutants lacking the chloroplast GSH transporters have a low cytosolic GSH poor and have impaired responses to pathogens. Inhibition of glutathione synthesis leads to decreases the redox potential of the cytosol and the nuclei and to marked changes in gene expression. Low GSH availability leads to failure of the apical root meristem because of an arrest of the cell cycle at G1. GSH is recruited and sequestered in the nucleus early in the cell cycle by mechanisms that remain to be identified. Interestingly, mutants in candidates for GSH binding on the nuclear pore complex show very strong repression of photosynthesis, especially under high light. This talk will consider the functions of glutathione in cellular redox homeostasis and possible roles in signalling between the chloroplast and nucleus.

Knowledge about the morphology and chemical composition of heterogeneous materials on a sub-micrometer scale is crucial for the development of new material properties for highly specified applications. However, each analytical measuring technique has limitations, which may be overcome by their combination. Confocal microscopy has been used to reconstruct three-dimensional images of micro-objects by using a spatial pinhole to eliminate out-of focus light in specimens thicker than the focal plane. Raman spectroscopy on the other hand is able to determine the chemical compositions of materials. The confocal Raman microscope combines Raman spectroscopy with high resolution confocal microscopy. The discrimination of out of focus information used in confocal microscopy is particularly beneficial for confocal Raman imaging since it reduces the volume from which the Raman spectrum is collected. Due to the confocal principle, depth information from transparent materials can be easily obtained, leading to full three dimensional chemical reconstructions of the material’s composition. The combination of confocal Raman microscopy with SPM and true surface microscopy permits characterization of materials at submicron resolution, as well as on mm-rough surfaces across large areas. Examples from various fields of applications will be presented.

Multiple environmental changes challenge traditional notions of ecological restoration. One option for the future may be to plant mixtures of native species to achieve desired ecosystem functions such as tightly cycling nutrients, carbon sequestration, resistance against weed invasion and prevention of soil erosion. However, it remains unknown how best to do this.

Are there trade-offs among functions? Do relationships depend on the traits of planted species? In this talk, Mike will present the theoretical and empirical foundations of the Ridgefield Experiment, which aims to shed light on these questions. He will present early results, and a broader meta-analysis of plant species effects on carbon storage led by his colleague Kris Hulvey. He will end by discussing implications for continued provision of ecosystem services into the future, and would be interested to discuss potential hydrological research questions that may be of interest to the Centre.

Bio,

Mike is an ecosystem ecologist interested in how continued system function depends on community composition and environmental change. He joined Richard Hobbs' Ecosystem Restoration and Intervention Ecology Research Group at UWA in April 2010. Together with colleagues, he established the Ridgefield Multiple Ecosystem Services Experiment in August of that year.

Prior to his move west, he looked at modelled grassland response to environmental change in Tasmania, and for his PhD, back at Imperial College London in the UK, the response of phosphorus to increases in nitrogen supply in a coupled plant-soil analytical model. Throughout his work, he aims to build and test theory through experimentation, with the aim of improving management and restoration of ecosystems into the future.

Science and Faith seem to be arguing a lot lately, so is their long term marriage over? The accusations are not pretty, not even true. Can we afford for them to split? Taking a leaf out of "Life of Brian", this talk will present the key players and principles of faith which pioneered modern science up to today. WXED is a series of data-rich multimedia presentations on the theme "What's Christianity(WX) Ever Done(ED) for Us?"

Crop rotation, where a legume, pasture, fallow or oilseed is grown after a cereal crop to manage soil borne disease and on occasions fix nitrogen, is one of the oldest technologies in agriculture.  However, we are still researching the concept because plant breeding helps some crops resist certain diseases, weed management practices evolve, and fertiliser can provide a comparatively cheap source of nutrition.   Farmers reacted to these changes by growing fewer break crops, but may now need to embrace seemingly unprofitable options like fallow on their farms.  Here we demonstrate how the Land Use Sequence Optimiser (LUSO) can generate optimum land use strategies for various biotic stresses and land use options. We compare the performance of optimal sequences to those local agronomists recommend, and then explore how variable the optimal and recommended sequences are by drawing predicted crop yields from simulated distributions generated by a crop model.  When challenged with variable seasons, the optimal sequence is often suboptimal and often the crop sequence has little bearing on the financial outcome. In other situations, the crop sequence choice will heavily influence the financial outcome for the farmer.  I will discuss the deterministic and stochastic versions of LUSO, and the implications of the above findings.

Roger Lawes is a Senior Research Scientist at CSIRO who works across a range of projects in farming systems.  He has research interests in crop modelling, plant breeding, farming systems modelling, agronomy and applied statistics.  Prior to joining CSIRO 12 years ago he completed a PhD at the University of Queensland.

Scientists have wondered for some time whether plants, like animals, can truly learn from the past and adjust their future behavior appropriately. We adopted the same approach used in studies of animal learning and memory and put the sensitive plant Mimosa to the test.

We found that plants too can learn, and rapidly, when circumstances demand it, but most importantly they remember what has been learnt for several weeks (at the very least). These findings demonstrate that memory is not property special to organisms with a nervous system, inviting us to re-examine the fundamental mechanisms shaping behavior across living systems.

The Art of Zhen Shan Ren (Truthfulness, Compassion, Forbearance) takes viewers through the story of Falun Dafa - from its introduction to the public in 1992, through the beauty and enlightenment of the practice, to the unjust and unrelenting persecution, moving forward through the peaceful resistance of Falun Dafa practitioners worldwide who seek to bring an end to the persecution, then through themes of karmic retribution, salvation and grace, and finishing with a moment of choice.

Storytelling has long been one of fine art's greatest joys, and this Exhibition's ability to cross cultural, lingual and ethnic barriers is highlighted each time it is shown.

Inspired by tradition and divinity, the artists paint - often collaboratively - stories either experienced by themselves or shared by fellow Falun Dafa practitioners worldwide. Realist oil painting, or Neo-Renaissance, was chosen as the style for its narrative capabilities, accessibility and, above all, its purity.

The Exhibition aims to educate and draw focus to an unjust persecution - to record a moment in time when the universal principles of Truth, Compassion, Forbearance are openly opposed. It also highlights the danger of becoming involved in the persecution through state-run ventures such as forced labour and forced organ harvesting of Falun Dafa practitioners. Outlasting these sombre themes, however, is a steady message of hope and fulfilment, as the enduring courage and belief of practitioners bring positive change in numerous dark settings.

A central hope of founding artist Professor Zhang's mission is to promote, through fine art, the understanding that freedom of belief is a fundamental human right, and to raise awareness.
