Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests. [PDF]

open access: yesNew Phytol
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...
