摘要: Four replicate outdoor microecosystems were constructed, utilizing “ sodded” Spartina alterniflora salt marsh plots (with attendant fauna and flora) contained within polyvinylchloride (PVC) metabolism chambers which open to the atmosphere. This study was designed demonstrate replicability of microecosystem units observe how closely structural functional processes “tracked” those natural site. paper describes an approach design provides a rationale for measuring selected community structure units. Each unit consisted 6 m2 with substrate intact depth 18 cm provided flow‐through sea water system simulate following characteristics tides at site: (1) sheet flow, (2) real time synchrony tides, (3) inundation, (4) duration inundation. In addition, each had flow measureme...
