| Summary: | Marine benthic communities, including meiofauna, have commonly been used as a focus of monitoring programs and of research into the effects of human activities in the marine environment. In Antarctica, benthic communities have been shown to be good indicators of human impacts, however, there is very limited information on Antarctic meiofaunal communities and how they may respond to anthropogenic disturbances. The main types of contamination present in marine sediments around Antarctic stations are metals and hydrocarbons. A survey of sediment meiofaunal communities was done at Casey Station, Antarctica, with sampling at a range of spatial scales, from 10 meters to kilometers, to determine the spatial patterns of community composition and abundance. This included a comparison of control and disturbed areas (adjacent to old waste disposal sites). An MDS of all 47 samples supported by one way ANOSIM (Global R= 0.955, P< 0.001) showed the variation within locations was less than the variation between ... |
