"A new theory of plant evolution suggests that the 400 million-year drive of flora across the globe may not have been propelled by the above-ground traits we can see easily, but by underground adaptations that allowed plants to become more efficient and independent.

As plant species spread north and south from their nutrient-rich tropical beginnings, the fine tips of their roots became narrower and more widespread to help them explore increasingly poor soil for vital nutrients, according to a Feb. 21 study in the journal Nature led by researchers from Princeton University and the Chinese Academy of Sciences (CAS) in Beijing. In addition, as plants spread into unpredictable environments such as arid deserts they grew less dependent on the symbiotic fungi -- or mycorrhiza -- that colonize roots and help host plants obtain the essential plant nutrients nitrogen and phosphorous.

The findings reconsider how plants adapted to new environments as they evolved, said corresponding author Lars Hedin, the George M. Moffett Professor of Biology and chair and professor of ecology and evolutionary biology and the Princeton Environmental Institute. Scientists have in the past focused on above-ground characteristics, primarily leaf traits and the efficiency with which plants absorb sunlight for photosynthesis, he said.

Instead, Hedin said, he and his colleagues have found for the first time that root diameter and reliance on fungi -- or the lack thereof -- are the traits that most consistently characterize the plant community across entire biomes, which are large distinct communities of animals and plants such as a desert, temperate forest or savanna.

"These are the secret strategies that plants have used over time to take over the world," Hedin said. "Our goal was to unlock the understanding of those strategies, and our findings offer a new global theory for plant evolution. Hidden underground there has been a tremendous game of survival-of-the-fittest and we are fortunate to have the first-ever view of the science of that game".

Wallagunda River Falls
Mist streams across the first plunge of this highland waterfall.
As promised, the ebook version of Wild Waterfalls of South Eastern Australia, is FREE on Amazon starting right now for the next five days. Head over to https://www.amazon.com/dp/B079VRXB9T. Enjoy, and thanks for the support!

The river drops 330m (1080’) in four plunges to the Kangaroo River. See the lookout top-left of the fall, for scale.

The Governors of the Australian Colonies took a keen interest in locating east coast waterfalls, using them as part justification for pushing rail and carriage ways into the wilderness. This plunge was named after Somerset Lowry-Corry, the Irish 4th Earl Belmore by an expedition in 1870). Belmore lent support to the introduction of legislation for financial probity and free education and helped diffuse a (disorganized) Fenian uprising in the southern districts after the assassination of Prince Albert in Sydney. While the name of the falls recalls a thoughtful colonial leader, i prefer using the ancient First People's name for the river as it plunges into the Barrengarry Valley.
