A pair of biologists, one with West Liberty University, the other with Arizona State University, both in the U.S., has found evidence that challenges theories surrounding bright coloration always functioning as an adapted ...
Fine roots (≤2 mm in diameter), the main conduit for resource uptake in the plant-soil continuum, are one of the most metabolically active organs of trees. Due to the difficulty of directly observing root dynamics, quantifying ...

A phylogenetic tree or evolutionary tree is a tree showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor. In a phylogenetic tree, each node with descendants represents the most recent common ancestor of the descendants, and the edge lengths in some trees correspond to time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units (HTUs) as they cannot be directly observed.
