【 摘 要 】

Two fundamental aspects of lamprey biology were examined to provide tools for population assessment and determination of critical habitat needs of Columbia River Basin lampreys (the Pacific lamprey, Lampetra tridentata, and the western brook lamprey, L. richardsoni). In particular: (1) we examined the usefulness of current diagnostic characteristics in identification of larval lampreys, specifically pigmentation patterns, and collected material for development of meristic and morphometric descriptions of early life stages of lampreys, and (2) we examined the effects of temperature on survival and development of early life stages of Columbia River Basin lampreys.
