“Individual(s) ….embrace a new paradigm for all sorts of reasons ... . Some of these … lie outside the sphere of science entirely. Others depend upon idiosyncrasies of autobiography….” (Kuhn, 1970, p.l52). I will highlight some “idiosyncrasies of autobiography” that have led to enjoying an academic life – the opportunity to research and teach, to construct and communicate knowledge. I plan to illustrate how psychometrics, a field in which I had the opportunity to ignore or embrace an emergent, non-standard statistical paradigm, has lead beyond mathematical modelling to areas such as the philosophy of science, the sociology of knowledge and academic controversy. I plan to also illustrate the challenges in negotiating the complex world of academic research and communication.

Complex I has several unique features in plants. Most notably, it includes 15 extra subunits, some of which introduce side activities into this respiratory enzyme. For example, subunits resembling an archaebacterial gamma-type carbonic anhydrase form an integral part of complex I in plants. These carbonic anhydrase subunits constitute a spherical extra domain which is attached to the membrane arm of complex I on its matrix exposed side. Furthermore, L-galactono-1,4 dehydrogenase (GLDH), which catalyses the terminal step of ascorbate biosynthesis in plants, is associated with complex I in plants. Novel data on the structure of the NADH dehydrogenase complex and its multiple functions in plant cells will be presented and discussed.

My research shows that the chemical mimicry crucial to sexual deception is responsible for reproductive isolation and potentially even speciation. I also show through mating system analysis and studies of wasp behaviour that this strategy is a superbly adaptive solution to the problem flowers face of simultaneously attracting pollinators before persuading them to leave quickly.

Abstract: The oceans, bounded by the atmosphere, lithosphere and shore, and covering 70% of the Earth's surface remain a poorly understood component of the Earth system. The changing climate, ocean circulation and chemistry, and depletion of ocean life are increasing at an alarming rate, largely a consequence of human activities. It is imperative to improve public understanding of the changes, consequences and possible future options, and to develop responsive informed public policies. A more quantified scientific database is required not achieved from a century of investigations using buoys, battery operated instruments and ship-based investigations. Advent of the first cabled ocean observatories (e.g. in Canada (NEPTUNE Canada, VENUS), US (OOI, MARS), Japan (DONET), China, Taiwan (MACHO), and European Union (EMSO)) demonstrates challenges, benefits, opportunities and added values for ocean science and commercial applications. Introducing abundant power and high bandwidth communications into diverse ocean environments allows: discrimination between short and long-term events, interactive experiments, real-time data/imagery, and complex multidisciplinary teams interrogating vast interoperable databases over decades. Cabled observatories will transform ocean sciences, with a progressive wiring of the oceans. NEPTUNE Canada completed installation of the subsea infrastructure with over 100 instruments in 2009-10, establishing the world's first regional cabled observatory (northeast Pacific; 800km backbone cable, with five nodes on the coast, continental slope, abyssal plain, and ocean-spreading ridge (100-2660m)). Principal scientific themes are: plate tectonic processes and earthquake-tsunami dynamics; seabed fluid fluxes and gas hydrates; ocean/climate dynamics and biotic effects; deep-sea ecosystem dynamics; engineering/computational research. New knowledge, scientific interpretations, and policy applications are addressing: ocean/climate change, ocean acidification, mitigating natural hazards, non-renewable and renewable natural resources. Socio-economic benefits include: resource/hazard/environmental management, sovereignty, security, transportation, data services, and public policy.

South-western Australia was a part of Gondwanaland, and some of the most ancient parts of the Earth’ crust can be found here. Other parts of the landscape originated more recently from calcareous marine deposits [1]. Therefore, the soils of Western Australia are amongst the most heavily leached and nutrient-impoverished in the world. Moreover, the soils on lateritic profiles tightly bind phosphate, so that, phosphorus (P) is also poorly available to plants that are not adapted to these conditions. The old, climatically buffered ancient landscape (OCBIL) of south-western Australia is also one of the world’s hotspots of higher plant species diversity [2]. Therefore, this environment offers a unique opportunity to study plant adaptations to nutrient-poor conditions [3, 4].

A relatively large proportion of species from the P-poor environments in Western Australia cannot produce an association with mycorrhizal fungi, but, instead, produce cluster roots or dauciform roots [5, 6]. These specialised roots are an adaptation both in structure and in functioning; they release large amounts of exudates, in particular carboxylates [7]. Cluster-root-bearing Proteaceae in Western Australia occur on the most P-impoverished soils, whereas the mycorrhizal Myrtaceae tend to inhabit the less P-impoverished soils in this region [8].

The functioning of cluster roots in Proteaceae and Fabaceae has received considerable attention. Dauciform roots in Cyperaceae have been explored less [9, 10], but they appear to function in a similar manner [11]. The growth of specialised cluster or dauciform roots in species of the Cyperaceae, Fabaceae and Proteaceae is stimulated when plants are grown at a very low P supply, and suppressed when leaf P concentrations increase [5, 7]. These specialised roots are all short-lived structures, and they release large amounts of carboxylates during an ‘exudative burst’ at rates that are considerably faster than reported for non-specialised roots of a wide range of species. The carboxylate release plays a pivotal role in mobilisation of P from P-sorbing soil [5].

Because the world P reserves are being depleted whilst vast amounts of P are stored in fertilised soils, there is a growing need for crops with a high efficiency of P acquisition. Some Australian native species have traits that would be highly desirable for future crops. The possibilities of introducing P-acquisition efficient species in new cropping and pasture systems are currently being explored [12, 13]. In addition, possible strategies to introduce traits associated with a high P-use efficiency into future crop species are considered promising.

High P-use efficiency in Proteaceae includes a highly efficient and proficient mobilisation of P from senescing leaves [14]. In addition, many species operate at extremely low leaf P concentrations exhibiting rates of photosynthesis similar to crop plant; expressed per unit leaf P, their rates of photosynthesis are extraordinarily high [4, 14]. I will explore what traits these species have that allow them to exhibit high rates of photosynthesis at very low leaf P concentrations.

Biography

I was born on a farm in the Netherlands in 1950 and completed my undergraduate degree in biology (1976), with a bachelor’s degree in biochemistry, followed by research projects in plant physiology and microbiology. I finished my PhD degree (1979) at the University of Groningen in the Netherlands, working on (cyanide-resistant) plant respiration and effects of flooding. My PhD supervisors were Dr Rinie Hofstra, and Professors Pieter Kuiper and Rienk Brouwer.

After completion of my PhD, I did postdoctoral work at the University of Western Australia, with Professor John Pate, Melbourne University, with Dr Michael Dalling, and the Research School of Biological Science at the Australian National University, with Professor Barry Osmond, working on various aspects of the metabolism and transport of carbon and nitrogen in wheat, white lupins, and a range of other species. After two years as a postdoctoral fellow back in Groningen, I was offered the chair in Ecophysiology at Utrecht University (in 1985).

While in Utrecht, I continued work on plant respiration and started a new program on the physiological basis of variation in plant growth rate and productivity. Twenty eight fascinating theses have come to fruition under my supervision during that great time.

My teaching activities in ecophysiology have led to the completion of a textbook, Plant Physiological Ecology, Springer, New York, just before I moved to UWA. The textbook was translated in both Chinese and Persian. The second, completely revised edition of this book appeared in 2008.

For three years, after my move to UWA, I maintained a fractional appointment at Utrecht University, to promote exchange of students between Utrecht University and UWA and to build collaborative research programs.

PS* This seminar is free and open to the public & no RSVP required.

Society for Ecological Restoration Australasia (SERA) meetings aim to provide an essential international forum for scientists and practitioners who look to restoration as a means to conserve the planet's dwindling biodiversity and failing ecosystems. These meetings provide a critical platform to assist us in defining the principles of restoration, understanding goals and milestones, debating what ecosystem functions to measure and closing the gap between the science of restoration ecology and the practice of ecological restoration.

The inaugural conference of the Society for Ecological Restoration Australasia (SERA) will be held in Perth, Western Australia, on 28-30 November 2012. For land managers, scientists and practitioners who work in biodiversity restoration, this SERA meeting will provide a critical international forum at a time of significance for the region's species, ecosystems and landscapes.

The course is designed for people with knowledge of basic statistics who want to learn more about designing and analysing experiments.
