摘要: Macquarie Island, in the sub-Antarctic, is location of one four permanently staffed bases operated by Australian Antarctic Division. As part a wider programme investigating effects human presence on and sub-Antarctic ecosystems, this study evaluated impact small sewage outfall at Island epifauna living within turfs intertidal red alga Chaetangium fastigiatum. Sampling was conducted during early December (austral summer) both 1996 1997 six sites, two sites each three adjacent bays. The site closest to 3 m from point discharge. Data analyses population community levels failed demonstrate significant effect outfall. Small scale spatial patterns, probably related wave exposure, inter-annual variation recruitment, are suggested as main causes patterns epifaunal dominance study.
