While walking through the Fynbos, have you ever wondered what occurs right under our boots?🌱
Hidden beneath the soil is a silent microscopic society known as Arbuscular Mycorrhizal Fungi (AMF)🧫. They weave together between the roots of flora such as daisies, currants, peas, etc. Together they create a hidden living network and every plant that attaches themself to the AMF is essentially "plugged" into the network which is used as a form of communication between different species!🌐
When tough times strike such as droughts, insect attacks, etc. The network allows the different species to redistribute water and other vital resources in support of their struggling neighbour 💚. Even wilder? At the same time the stress signals received from the struggling neighbour also indicates to the receiving flora that they need to build up their defenses before the threat arrives 💪.
How does the AMF survive attached to the roots? They create a mutualistic relationship 🤝. These fungi are expert phosphorus miners unlocking a scarce nutrient from the ancient fynbos soils and essentially trading it to the plants for carbon-rich sugars and lipids 🌼.
But not all Fynbos species can be "plugged" into this network, certain species like Ericas have evolved alongside their own specialised fungal networks, while other species like Proteas don't rely on Mycorrhizal fungi at all, instead they solely rely on their fine cluster roots 😲.
In the harsh landscapes of Fynbos survival isn't just about competition, it's about connection 👫.
