The general perception of the Australian Outback as being a bland, empty void couldn't be further from the truth. "Some plants form symbiotic root relations with fungi and some with bacteria, while capture and digest insects for the nutrients that they contain. Moreover, another broad group of species exude organic compounds that increase nutrient availability," said Dr. Graham Zemunik. "The Australian kwongan is one of Earth's plant diversity hotspots, just like tropical rainforests." The research team is in fact supporting an initiative to have the kwongan recognized as a UNESCO World Heritage site for this reason.
The findings, like the kwongan as a whole, are of global importance. "Ecosystems all around the world are being altered at an alarming rate. In order to protect biodiversity as best as we possibly can, we need to understand how these systems work. To achieve that goal, our study shows that it's important to go beyond what's immediately visible to study what nature has hidden below ground," Dr. Zemunik said.
