Experimental Manipulation of Canopy Density in a Temperate Seagrass [Amphibolis griffithii (Black) den Hartog] Meadow: Effects on Sediments

Thirty 3 m diameter plots were established in Warnbro Sound, Western Australia in early 1991, within an Amphibolis griffithii meadow, and the shoot densities manipulated to 0, 25, 50, 75 and 100% (control) by pruning. These experimental manipulations were monitored and maintained on a monthly basis until March 1993. The effects of these density changes on sediments were investigated.

1991年初，研究人员于西澳大利亚州沃纳布罗湾（Warnbro Sound）的格里菲思海神草（Amphibolis griffithii）草甸内设置30个直径3米的样地，并通过修剪手段将样地内海草地上茎密度调控至0、25%、50%、75%及100%（对照组）。自实验开展至1993年3月，该密度调控处理均按月开展监测与维持工作。本研究针对上述密度变化对沉积物的影响进行了探究。
