Bacteria in estuarine (Bras d'Or Lake) sediment
The number of bacteria in sediment from an estuarine environment, salinity 20–25‰, in Cape Breton Island, Nova Scotia, was determined by membrane filter counts from 73 fresh (on board ship) and 67 frozen (in laboratory) samples from 20 stations and the results compared. Taylor's model (log vari...
