Predicting the causes and consequences of plant invasions. Invasive plants are one of the most costly and significant environmental threats in Australia. To deal with this threat we need to understand how and why certain plant species are able to invade into and dominate native communities. The aim of this project is to uncover the rules that govern this environmental threat. The project endeavours to use theory to predict the outcomes that would be observed given different underlying rules, and ....Predicting the causes and consequences of plant invasions. Invasive plants are one of the most costly and significant environmental threats in Australia. To deal with this threat we need to understand how and why certain plant species are able to invade into and dominate native communities. The aim of this project is to uncover the rules that govern this environmental threat. The project endeavours to use theory to predict the outcomes that would be observed given different underlying rules, and then test these predictions with field experiments. By uncovering the rules that govern invasions, this project could provide fundamental knowledge to assist in managing the environmental threat posed by new and emerging weeds.Read moreRead less
Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use a ....Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use and numerical modelling, to assess resilience of ephemeral streams to changes in flows resulting from mining activities and climate-related shifts in recharge. Expected outcomes of the project include providing appropriate context for evaluating and adapting management to conserve scarce water resources. This project should significantly contribute to the sustainable management of both mineral and groundwater resources.Read moreRead less
