a Abbreviations: VMM, virus-mediated mortality; GMM, grazing-mediated mortality; SS, standing stock; and BP, bacterial production. b VMM, viral production/burst size of 41 according to Brum and Colleagues [32]; GMM, (specific grazing rate/net growth rate) × net bacterial production. VMM of bacterial standing stock = (VMM/SS) × 100. GMM of bacterial SS = (GMM/SS) × 100. VMM of total available bacteria = [VMM/(SS + BP)] × 100. GMM of total available bacteria = [GMM/(SS + BP)] × 100. Bacterial production virally lysed or grazed = [(VMM + GMM)/BP] × 100. c Bacterial carbon conversion factor of 12.4 fg C cell−1 reported by Fukuda and colleagues [28].
