Abstract Abstract We studied the growth andsurvival of Spectacled Eider (Somateriafischeri) ducklings to30 days of age along the lower KashunukRiver on the Yukon-Kuskokwim Delta from 1995 to2000. We replicated this study at a second site,Kigigak Island, in 1999 and 2000. Age-adjustedestimates of duckling mass and survival at30 days posthatching were highly variable.Duckling survival was consistently higher onKigigak Island in 1999 and 2000, averaging67%, while survival on the Kashunuk Riveraveraged 45% during the same time period.Duckling survival was negatively related tohatching date. At the Kashunuk River site our datasupported models that indicated age-adjusted massvaried with habitat type and declined with hatchingdate. Ducklings from Kashunuk River were heavier in1999, while ducklings from Kigigak Island wereheavier in 2000. However, we found a positivecorrelation between 30-day duckling survival andage-adjusted mass, suggesting a localizedenvironmental effect on both parameters. Weconclude that predation may be the proximatemechanism of mortality, but habitat conditions arelikely the ultimate factors influencing ducklingsurvival. Geographic variation in rates of ducklingsurvival and apparent growth suggest that spatialheterogeneity in population vital rates isoccurring at multiple levels.

A study was made of the growth of rhizobia outside the host plant in three high humus mixtures and a mineral soil. Rhizobia grew better in pure cultures than in an unsterile base. Incubation in Erlenmeyer flasks gave, as a rule, higher counts than in paper cartons. Addition of a mixture of sucrose, calcium carbonate, sodium chloride, dipotassium phosphate, and magnesium sulphate led to increased numbers of rhizobia in pure culture in all bases used, and produced increased numbers in the unsterilized mineral soil also. Addition of this mixture to the unsterile high humus bases increased the total numbers of bacteria, but not the number of rhizobia. When the bases were sterilized, the highest counts of rhizobia were obtained in the high humus bases. When sterilization was not carried out, the greatest numbers of rhizobia occurred in the mineral soil. In tightly stoppered flasks that did not permit aeration, the rhizobia appeared to die out completely when stored for more than a few days, whereas in loosely stoppered flasks the counts remained at a high level until the base became desiccated.
