Regional Impacts
| Ecological Impact | Competition | |
| The native periwinkles L. scutulata, L. plena and L. keenae were absent in the vicinity of introduced L. saxatilis populations in San Francisco Bay (Carlton and Cohen 1993). However, the mechanisms for this apparent exclusion have not been studied, to our knowledge. | ||
