The independent and interactive effects of snail grazing and nutrient enrichment on structuring periphyton communities
Full text linkWe investigated the independent and interactive effects of nutrient enrichment and snail grazing on structuring periphyton communities in a northern temperate lake. Nutrient releasing substrates and grazer enclosures were used to simultaneously manipulate nutrient availability and herbivory. Periphyton was allowed 18 days to accrue before grazers ( Elimia livescens = Goniobasis livescens ) were introduced.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42878/1/10750_2004_Article_BF00006063.pd
