說明
The experiment was designed to study long-term changes in communities strucutre in response to global change (climatic change) and local anthropogenis pressures (e.g. eutrophication). Fine sand macrobenthic communities are monitored two to five times a year at the "Pierre Noire" site. The different parameters wich are measured are (1) total and specific abundances, (2) specific richness

取樣方法
Macrofauna is sampled using a Smith McIntyre grab covering a surface of 0.1 m2. Ten replicates are collected at each sampling date.

方法步驟描述:
- After collection, the sediment was sieved (1 mm circular mesh) and the retained material is fixed with 10 % neutralized formalin prior to analysis in the lab. In the laboratory, organisms are sorted, identified to species level and stored in a 70% ethanol solution.
