Effects of intra-population variation in dogwhelk drilling on the abundance and size of Mytilus californianus mussels

Abstract:

Few eco-evolutionary studies have analyzed the impacts that evolutionary processes have on community dynamics in a natural field setting. We studied the effects of intra-population variation in predation in a marine dogwhelk (Nucella canaliculata) on mussel bed succession. We outplanted dogwhelks that were reared on four early-life diet treatments and showed evidence of differential mortality and variation in drilling capacity in the lab to experimental field cages and followed the trajectory of succession over the course of a year. At the end of the experiment, the organisms within the cages were collected and the mussels (Mytilus californianus) were measured. Mussels represent the end stage of succession, thus we studied whether variation in drilling traits would impact the size and structure of the mussel bed.

Methods & Sampling

Dogwhelks (Nucella canaliculata) were reared in the laboratory on four early-life diet treatments for the first 3 months of life. In July of 2021, adult dogwhelks were outplanted to field cages (stainless steel mesh cages with removable lids that were bolted to the substrate) at Bodega Marine Reserve. The plots within the cages when the dogwhelks were outplanted were at a mid-successional stage, containing a mix of acorn barnacles, gooseneck barnacles, and a few small mussels. The cages were in a block design with five cages placed near each other. The dogwhelks outplanted to a given block were from the same family (dogwhelks from the same egg capsule cluster were referred to as a family of snails) with each cage getting dogwhelks that were reared on one of the four early life diet treatments, plus one cage was a reference cage that did not get any dogwhelks. The dogwhelks remained in the cages for the next year until August 2022 when the dogwhelks and all of the mussels within the cages were collected and brought back to the laboratory. The organisms were sorted, the number of mussels present in each cage was counted, and their lengths (along the anterior to posterior axis) were measured. Very small mussels (<10 millimeters) were excluded, as these mussels were difficult to evaluate accurately.

Block	Block number. Plots were in a block design such that 5 plots were near each other. Each block contained snails from the same family or egg capsule cluster, with each cage randomly assigned to contain snails from one of the four early-life diet treatments, plus a reference cage with no dogwhelks.
