Effects of early-life diet on Nucella canaliculata drilling phenotype quantified in the laboratory after rearing on different prey treatments

Abstract:

The growing field of eco-evolutionary dynamics has highlighted the importance of reciprocal feedbacks between evolutionary and ecological processes. We tested whether selection could act on existing within-population variation in a predatory trait in the marine dogwhelk, Nucella canaliculata. We reared newly hatched dogwhelks on four prey treatments (thin-shelled Mytilus trossulus, two treatments of M. californianus from two populations known to differ in adult shell thickness, and acorn barnacles). To quantify dogwhelk phenotype, we tested the surviving adult dogwhelks on their ability to drill mid-sized (5-7cm long) M. californianus. We found evidence that dogwhelk phenotype varied among the early-life diet treatments.

Methods & Sampling

Adult dogwhelks were scored for their ability to drill mid-sized (5 to 7 centimeters long) Mytilus californianus mussels during a 100-day laboratory experiment. 12 adult dogwhelks from 18 Bodega Marine Reserve families (dogwhelks that hatched from the same egg capsule cluster were considered a 'family' of snails) and from 4 Soberanes Point families were scored. Dogwhelks were held in individual containers with flowing seawater. Checks were performed routinely every 3 weeks to assess dogwhelk drilling. If a mussel was drilled, it was recorded and replaced with another mussel. Two metrics for dogwhelk drilling were quantified – a binary trait if a dogwhelk was able to drill at least one mussel during the course of the experiment, and the total number of mussels drilled per snail. The experiment was performed in two rounds due to space limitations.

BCO-DMO Processing

- Imported original file "Effects of early-life diet on Nucella canaliculata drilling phenotype.xlsx" into the BCO-DMO system.
- Flagged "NA" as a missing data value (missing data are empty/blank in the final CSV file).
- Added columns for site Latitude and Longitude.
- Renamed fields/columns to comply with BCO-DMO naming conventions.
- Saved the final file as "918460_v1_Nucella_canaliculata_drilling_phenotype.csv".
