In biology, phylogenetic trees represent the evolutionary history and diversification of species—the "family tree" of Life. Phylogenetic trees not only describe the evolution of a group of organisms ...

A study is reframing a fundamental question in plant evolution: What made trees possible? Researchers from Cal Poly Humboldt, ...

Once you look at trees through the eyes of a dendrochronologist, you never quite see the leafy wonders the same way again. Peel away the hard, rough bark and there is a living document, history ...

What makes a tree a tree? Or rather, why can we recognize trees in even quite abstract depictions when they are so varied in nature? Researchers have found a clue in the branches, and used math to ...

Tornadoes, hurricanes, and other extreme windstorm events cause millions of dollars in structural damage and related losses each year. They can also significantly damage ecosystems systems, driving ...

Researchers used more than 1,400 climate-sensitive tree-ring chronologies from multiple tree species across North America to reconstruct the Palmer drought severity index (PDSI), a widely used soil ...
