Factors affecting bacterial biomass and growth in the Duplin River estuary and coastal Atlantic Ocean.
Provedor de dados: 5
Autores: Fallon, R; Newell, S; Sherr, B; Sheer, E.
Bacterial numbers and growth rates were measured in coastal, planktonic systems of the Western Atlantic ocean. Seasonal responses in growth rates of the bacterial assemblage were present at some sites, but these may be related to seasonal changes in substrate supply rather than to changes in temperature. Bacterial growth rates tended to decline with increasing distance from shore. There was evidence for predator-prey population cycles in the bacteria and &lt; 17 mu m protozoa in the Duplin River Estuary which may indicate that the bacterial assemblage serves as prey for protozoan populations. In summer, a significant negative correlation between mu (instantaneous growth rate) and cell numbers in the bacterial assemblage indicated that substrate limitation...
