Life Histories of Aquatic Species

Science Center Objects

Many species exhibit diverse behaviors that translate into different patterns of habitat use and demography. Diversity within species can be related to a complex array of processes, including genetic and maternal influences, and external environmental drivers. Our work addresses life history diversity in salmon and trout, including Pacific salmon, steelhead and rainbow trout, cutthroat trout, and bull trout. We have also begun to study life histories of lesser known species, such as western pearlshell mussels (Margaritifera falcata), which can live for more than 100 years in rivers. Understanding the full range of life histories and how they link to environmental conditions is critical for understanding long-term species persistence and viability.
