Forests and Their Canopies: Achievements and Horizons in Canopy Science [PDF]

Trends in Ecology & Evolution, 2017
Forest canopies are dynamic interfaces between organisms and atmosphere, providing buffered microclimates and complex microhabitats. Canopies form vertically stratified ecosystems interconnected with other strata. Some forest biodiversity patterns and food webs have been documented and measurements of ecophysiology and biogeochemical cycling have ...
