Polychaete feeding guilds from Georges Bank, USA

Polychaete feeding guilds from Georges Bank, USA 227 62 62 2 3 D. Maurer W. Leathem College of Marine Studies University of Delaware 19958 Lewes DE USA Abstract Based on 408 quantitative samples distributed over two seasons (winter and spring) and 42 stations, from Georges Bank, New England, USA, the feeding guild classification presented by Fauchald and Jumars was examined. Hypotheses involving the association of particular feeding guilds with environmental variables were posed and tested. In this study, herbivore, motile, jawed (HMJ); filtering and surface deposit feeding, sessile or discretely motile, and tentaculate (F-SD-SDT); burrowing, sessile, non-jawed (BSX); surface deposit feeding, motile, non-jawed (SMX); carnivore, motile, jawed (CMJ), and filter feeding, discretely motile, non-jawed (FDT) were the major feeding guilds of polychaetes. There were more significant associations between feeding guilds and depth, dissolved oxygen, and mean phi and gravel than any other environmental variables. Some significant relationships between feeding guilds and depth, fine-grained sediment, nutrition in sediment (carbon, nitrogen, bacterial biomass, and microbial biomass) emerged. Burrowing, motile, non-jawed (BMX), surface deposit feeding, discretely motile, tentaculate (SDT) and FDT increased with depth. BMX, BSX, and FDT increased with carbon, microbial biomass, and nitrogen, respectively. Some preliminary polychaete feeding surfaces were posed. Nantucket Shoals and Georges Bank were characterized by HMJ and F-SD-SDT; Northern Slope by FDT; Southern Slope by FDT and HMJ; Southwestern Slope by HMJ, SMX, BMX; and the Gulf of Maine by F-SD-SDT, SDT and surface deposit feeding, sessile, tentaculate (SST). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Marine Biology Springer Journals
