cylindricum trees. The vertical soil profiles were divided into 10 x 10-cm grid cells and the roots counted were distributed in three diameter classes. We fitted a root distribution model to our dataset. We found that vertical root distribution was shallower in Arenosols than in Ferralsols. ...
Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most
they transformed the wasteland into a soccer field with gates made of fir trees and lines drawn with lime. This marked the beginning of soccer matches being played by village teams in a league format, which was the precursor to the Village Super League in Guizhou.几...
See, without trees the ecosystem will not be suitable for life, affecting already endangered species. We transformed the remains of dead trees in deforested areas and built them into life-size sculptures that represented these threatened species in Colombia.

Early in spring, robins build their nests in trees. Some robins can live up to 12 years. These birds may build 20 or even 30 nests in their lifetime! The nests are made of grass, sticks and mud. The mud puts everything together. ...
A dark-haired African ape that is somewhat smaller than a gorilla, lives mostly in trees, and has a high degree of intelligence. Chimpanzees live in close-knit groups and have elaborate social interactions. They are the closest living relatives of humans. ...
Bamboo, the fast-growing grass plant common to Africa, Asia and Latin America, has been used for thousands of years to build houses, bridges, and scaffolding(脚手架). 1 Yet, despite its excellent mechanical characteristics—bamboo is flexible, durable and has the strength of steel—this plant...
Foliar and litter mineral content of six common and economically useful trees of tropical West Africa along with the associated soils were determined. Individual cations varied considerably, and seasonal changes in leaf as well as soil magnesium, sodium, and potassium conten...
You may also see robins on lawns(草坪) in parks. They are looking for worms(寄生虫). and bugs(小昆虫) to eat there.Early in spring, robins build their nests in trees.Some robins can live up to 12 years old, according to the studies. These birds may build 20 or even 30 nests ...
Conifers grow in all climate zones and on all continents except Antarctica. They all bear their seeds within a cone or a structure superficially resembling a berry (true berries only exist among angiosperms). Most conifers are trees. Conifers appeared in the fossil record about 290 million ...
