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
Given the increasing pressure from extreme events due to climate change, the planting of new trees has become a priority in the political agendas of cities. However, the rush to plant trees often fails to account for the reduced performance and lifespan of trees in heavily urbanized areas and...

We observed substantial variation in soil chemical properties at the scale of individual trees and specific genotypes. While correlations among elements were observed both within and among sample types (soil, stem, root), above-belowground correlations were generally poor. ...
Critical coastal events, happening once a century in recent times, to occur every year on average. The news has been packed in recent months with severe climate and weather events—record-high temperatures from the Pacific Northwest to Sicily, flooding in Germany and the eastern United States, ...
Nests in old raptor nests, in tree cavities, and on top of broken off trees. Watches from a perch before flying down to catch small animals on the ground, at night. The Spotted Owl is a rare resident of mature forest, mostly in parts of the western and southwestern USA, even in Color...
Where is the plant growing? Is it planted in the sun when it should be in the shade? Are tree or shrub roots competing for moisture? Has compost or mulch been added? On shrubs and trees, think about where the roots are. The plant is probably not getting adequate water if it is only...

The records are from trees, ice, sediment, corals, speleothems, documentary evidence, and other archives. They range in length from 50 to 2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial. Nearly half of the proxy time series are ...
They forage on and near the ground, but males sing from a prominent perch. This beautiful bird occurs in pairs and nests in bushes and low trees. It is common in the eastern and southwestern USA, making it one of the most common birds of Arkansas. They are also present in southern ...
