Weed or feed? New pasture plants intensify invasive species risk
To meet increasing demands for livestock production, agribusinesses around the world are breeding new varieties of pasture plants. Unfortunately, many of the plant characteristics promoted for use in pasture – higher growth rates, greater resistance to disease, higher tolerance of environmental … Continue reading
Managing the Murray’s water to combat invasive species
About this time last year, I wrote an article for H2O Thinking, a water management magazine published by eWater (until recently the eWater CRC). While the turnaround time is nothing to envy, the piece found its place on the web earlier this week. In … Continue reading
Project kick-off: propagule pressure, functional traits, resource availability and plant invasion
As mentioned in a previous post, I was lucky enough to be awarded one of the inaugural ARC Discovery Early Career Researcher Awards (DECRA) late last year. I officially started my DECRA research in April, so I thought it was … Continue reading

New paper: The intermediate disturbance hypothesis and plant invasions: implications for species richness and management
Jan 2012 – Some colleagues and I have recently written a paper that examines the relationship between the intermediate disturbance hypothesis (IDH) and alien plant invasions. Published in Perspectives in Plant Ecology, Evolution and Systematics, the paper is structured around … Continue reading
Newsletter article: Causes, impacts and ways to manage exotic plant invasion along the River Murray
