Effects of common seagrass restoration methods on ecosystem structure in subtropical seagrass meadows.

摘要: Seagrass meadows near population centers are subject to frequent disturbance from vessel groundings. Common seagrass restoration methods include filling excavations and applying fertilizer encourage recruitment. We sampled macrophytes, soil structure, macroinvertebrate infauna at unrestored recently restored grounding disturbances evaluate the effects of these on ecosystem structure. After a year observations comparing filled sites both undisturbed reference disturbed sites, had low organic matter content, nutrient pools, primary producer abundance. Adding source increased porewater pools in meadows, but not sites. Environmental predictors infaunal community structure across treatments included texture pools. At one time scale, studied did result convergence between Particularly conditions may combine constrain rapid development associated infauna. Our study is important for understanding early recovery trajectories following using methods.
