| Notes | This book chapter discusses some freshwater crayfish that are common in coastal streams. It goes extensively into the biogeography of signal crayfish and events that influenced their distribution, including volcanism, glaciation, glacial-era floods, and stream captures. The fossil record is considered. The Columbia River signal crayfish (P leniusculus trowbridgii) is the subspecies found in most Oregon coastal streams. |
