Response of estuarine meiofauna assemblage to effects of fertilizer enrichment used in the sugar cane monoculture. Pernambuco, Brazil

摘要: application of inorganic fertilizer was used to simulate environmental eutrophication associated with the sugar cane monoculture. Meiofauna community structure is herein assess this experimental impact. Nine quadrangular areas (4m² each) were randomly defined in midlittoral estuarine area. Three these received a high dose (375 g/m² Nitrogen-Phosphorus-Potassium), three low (187.5 g/m²) and other represented control. The applied every week. Environmental parameters meiofauna sampled using three–to-four week intervals. Six samplings subsequently performed maintaining interval. counted identified major taxonomic groups. varied throughout areas. Control maintained their abundance values during study period, but within enriched decreased greatly. MDS ANOSIM analysis showed significant variation among also along period
