The study investigated the history of alpine and subalpine plants in south-central Tasmania over the past 15,000 years. By analysing fossil plant remains from Lake Dobson in Mount Field National Park researchers have uncovered evidence suggesting that the modern configuration of the vegetation near the treeline was reached c. 6000 years ago. These findings emphasise the individualistic plant responses and strategies during a time of significant environmental transformation, allowing us to understand how fast plant species can respond to such changes.

Invasive species are mostly controlled by herbicides that may result in non-target effects on essential soil fungi. Diverse fungal communities were obtained from a native tree and invasive grass species for herbicide testing. Herbicides containing pelargonic acid decreased species richness and Shannon diversity and fluazifop-p-butyl herbicides increased the relative abundance of pathogenic fungi.
