Making management decisions in the face of uncertainty: a case study using the Burdekin catchment in the Great Barrier Reef

Modelling and monitoring pollutants entering into the Great Barrier Reef (GBR) lagoon remain important priorities for the Australian and Queensland governments. Uncertainty analysis of pollutant load delivery to the GBR would: (1) inform decision makers on their ability to meet environmental targets; (2) identify whether additional measurements are required to make confident decisions; and (3) determine whether investments into remediation activities are actually making a difference to water quality and the health of the GBR. Using a case study from the Upper Burdekin catchment where sediment concentrations are the focus, herein we explore and demonstrate different ways of communicating uncertainty to a decision maker. In particular, we show how exceedance probabilities can identify hot spots for future monitoring or remediation activities and how they can be used to inform target setting activities. We provide recommendations for water quality specialists that allow them to make more informed and scientifically defensible decisions that consider uncertainty in both the monitoring and modelling data, as well as allowing the calculation of exceedances from a threshold

Physiological functions of malate shuttles in plants and algae

International audienceThe malate shuttle, as a valve for photosynthetic electron dissipation, has been proposed for >50 years, but only recently has this function been clearly demonstrated. The plastidial NAD-MDH is essential for embryogenesis and chloroplast development. This role is not due to its enzymatic activity but rather to its ability to stabilize a large AAA-ATPase complex at the inner envelope. The plNAD-MDH is therefore a moonlighting protein. The malate shuttle connects fatty acid biosynthesis in the chloroplast to mitochondrial reactive oxygen species (ROS) production and to programmed cell death in plants. The malate shuttle connects fatty acid catabolism in the peroxisome to photosynthesis and chloroplast metabolism in algae. Expression of malate shuttle components is responsive to CO2 levels. The latest results indicate its critical role in plant photorespiration and points to a possible role in the algal CO2-concentrating mechanism

Revealing beliefs: using ensemble ecosystem modelling to extrapolate expert beliefs to novel ecological scenarios

Ecosystem-based management requires predictive models of ecosystem dynamics. There are typically insufficient empirical data available to parameterise these complex models, and so decision-makers commonly rely on beliefs elicited from experts. However, such expert beliefs are necessarily limited because (i) only a small proportion of ecosystem components and dynamics have been observed; (ii) uncertainty about ecosystem dynamics can result in contradictory expert judgements and (iii) elicitation time and resources are limited. We use an ensemble of dynamic ecosystem models to extrapolate a limited set of stated expert beliefs into a wider range of revealed beliefs about how the ecosystem will respond to perturbations and management. Importantly, the method captures the expert uncertainty and propagates it through to predictions. We demonstrate this process and its potential value by applying it to the conservation of the threatened malleefowl (Leipoa ocellata) in the Murray mallee ecosystems of southern Australia. In two workshops, we asked experts to construct a qualitative ecosystem interaction network and to describe their beliefs about how the ecosystem will respond to particular perturbations. We used this information to constrain an ensemble of 10 community models, leaving a subset that could reproduce stated expert beliefs. We then interrogated this ensemble of models to reveal experts’ implicit beliefs about management scenarios that were not a part of the initial elicitation exercises. Our method uses straightforward questions to efficiently elicit expert beliefs, and then applies a flexible modelling approach to reveal those experts’ beliefs about the dynamics of the entire ecosystem. It allows rapid planning of ecosystem-based management informed by expert judgement, and provides a basis for value-of-information analyses and adaptive management
