Larger leaves favor photosynthetic production of a sugar-rich fluid to nourish the tree, but if the tree is too tall, the nutrient flow is slowed. Why are the leaves on the tallest trees all about the ...

What limits the height of trees? Is it the fraction of their photosynthetic energy they devote to productive new leaves? Or is it their ability to hoist water hundreds of feet into the air, supplying ...

Trees are tall. Humans, relatively speaking, are not. And we're not the most agile climbers in the animal kingdom, either. But we are crafty, and we can out-think even the most wizened redwood. But ...

The world’s tallest tree is found in northern California – it’s a redwood that stands 379 feet tall. This tree and its relatives are the largest single organisms in the world, but just how big can ...

How tall can a tree grow? Does sunlight or water limit the size and photosynthetic capacity of a leaf? Could constraints on leaf growth really determine the height of a tree? These are all questions ...

Scientists have created the first global map of forest height using satellite data. The map will improve estimates of how much carbon is stored in Earth’s trees and how much carbon dioxide they absorb ...

Forest scientists have used genetic modification to successfully manipulate the growth in height of trees, showing that it's possible to create miniature trees that look similar to normal trees -- but ...
