Title Fig.2. Oyster larval settlement rates on adult oysters in an open estuary, field experiment.
Downloaded 40 times
Description Data collected in the field, in an experiment established in an estuary. Excel software was used to create the data file. A)Monospecific Bags: data represent the rate of larval settlement on 9 of each adult oyster: conspecific Sydney rock oysters and native Pacific oysters, deployed in single-species mesh bags. Status indicates oysters that were deployed live or dead. B) Mixed basket: 20 of each Sydney rock oyster and Pacific, live and dead (total 80 oysters) were deployed in one basket. Summary indicates means and standard errors of the means of raw data.

Title Fig.3. Larval settlement rates in response to densities of adult oyster substrate.
Downloaded 35 times
Description Data collected in a controlled laboratory experiment, in 8 L replicate buckets. Excel software used to create the data. The number of Sydney rock oyster larvae settled per adult oyster is recorded. Adult oysters used as substrate were either A) Live or B) Dead. Two species of oyster were used; Sydney rock oyster and Pacific oyster. Oysters were placed in buckets in three densities; 1 oyster, 2 oysters and 3 oysters. Summary indicates the mean, and standard error of the mean.

Title Fig.4. Larval settlement rates on adult oysters restricted from feeding.
Downloaded 33 times
Description This data was collected in a controlled laboratory experiment, using 8 L replicate buckets. Excel software was used to create this data. The number of larvae settled on individual adult oysters is recorded. Adult oyster substrates were one of two species: conspecific Sydney rock oysters or non native Pacific oysters. Adult oyster were restricted from feeding by banding closed, left to feed normally with no band, or left to feed with a loose band to test effects of the band on larval settlement (band control). Data is summarised as means and standard error of the mean for each treatment.
