| Abstract | Individual heterogeneity can significantly affect population dynamics and management responses. For instance, variation in individual responses to environmental variability can reduce risk of extirpation of populations, as the portfolio effect dampens temporal variability in abundance. Moreover, differences in habitat use may cause individuals to respond differently to habitat management and climate variability. To explore the role of individual heterogeneity in population trajectories, population models need to incorporate individual-level variation. Integrated population modeling (IPM) is a population modeling approach that offers several advantages for sharing information and propagating uncertainty across datasets, and incorporating characteristics of individual heterogeneity. In this study, we developed an IPM for an endangered population of Chinook salmon (Oncorhynchus tshawytscha) in Washington State that accounts for individual heterogeneity in juvenile life history, spawning l |
