The math that describes the branching pattern of trees in nature also holds for trees depicted in art—and may even underlie our ability to recognize artworks as depictions of trees. Trees are loosely ...

Leonardo da Vinci’s sketch of a tree illustrates the principle that combined thickness is preserved at different stages of ramification. The math that describes the branching pattern of trees in ...

The reason why so many tree species can coexist in species-rich forests has long been a subject of debate in ecology. This question is key to understanding the mechanisms governing the dynamics and ...

Researchers have found almost identical patterns of tree diversity across the world's tropical forests. The study of over one million trees across 1,568 locations found that just 2.2% of tree species ...

Trees can be identified in winter by observing their needles, bark, branching patterns, and buds. Distinctive bark, such as ...
