Network representation of the 6,901 trees of the forest of life. The 102 NUTs are shown as red circles in the middle. The NUTs are connected to trees with similar topologies: trees with at least 50% of similarity with at least one NUT (P-value < 0.05) are shown as purple circles and connected to the NUTs. The rest of the trees are shown as green circles.
