Methods & Sampling

Individual Dendropoma (now Ceraesignum) maximum were collected haphazardly from seven sites in April and September 2008. Snails were removed with their shells in tact using a chisel and hammer. At the lab, snails were removed from the shell. Females were determine by the presence of a mantle slit and appearance of gonads. Length of capsules were measured in April to the nearest 0.01mm. The number of larvae in an egg capsule was determined by a subset of the capsules in a female. Weights that are the same are from the same female. Missing female weights are because those females were not weighed.

Instruments

Measuring Tape

Supplied Name: length was determined

Supplied Description:

In the lab the diameter of the opening of the shell was measured in samples from April.

Instrument Type

Generic Name: Measuring Tape

Generic Description:

A tape measure or measuring tape is a flexible ruler. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common tool for measuring distance or length.

scale

Supplied Name: balance

Supplied Description:

Snails were removed from the shell, and sex, length and wet mass were determined.
