A tree is a hierarchical data type that represents a set of connected nodes with a parent-child relationship. Learn about the types, applications, terminology and examples of trees in computer science.
Pando is a quaking aspen tree located in Fishlake National Forest, Utah, with an estimated 47,000 stems connected by a single root system. It is the largest tree by weight and landmass, and the largest known aspen clone, but its future is uncertain due to drought, grazing and fire suppression.
An arborescence is a directed rooted tree in which all edges are oriented away from the root. Learn more about the properties, types and applications of trees and arborescences in graph theory.
Trees with a single root may be viewed as rooted trees in the sense of graph theory in one of two ways: either as a tree (graph theory) or as a trivially perfect graph. In the first case, the graph is the undirected Hasse diagram of the partially ordered set, and in the second case, the graph is simply the underlying (undirected) graph of the ...
Moringa oleifera is a fast-growing, drought-resistant tree native to the Indian subcontinent, also known as drumstick tree, horseradish tree, or malunggay. It is cultivated for its seed pods and leaves, used as vegetables and herbal medicine, and can purify water.
The tree of life is a metaphor and research tool to explore the evolution and relationships of organisms. Learn about its history, from ancient diagrams to modern databases, and its applications in biology and paleontology.
Fungal diseases such as laminated root rot and shoestring root-rot can cause significant damage, and in plantation settings dominated by Douglas-fir monocultures may cause extreme damage to vast swathes of trees. [13] Interplanting with resistant or nonhost species such as western redcedar and beaked hazelnut [38] can reduce this risk.
Learn about the underground network of fungal hyphae that connects plants in forests and other ecosystems. Find out how mycorrhizal networks influence nutrient exchange, plant-plant interactions, and evolution.
