| 1d. Early life history and recruitment dynamics |
| Variation in recruitment and eventual population dynamics are closely associated with growth and mortality of marine and freshwater animals in the early life history stages. Key factors determining growth and mortality may be water temperature, food availability, predator abundance, and the interactions among these environmental factors. Atmospheric and oceanic regime shift may change ecosystem framework from a stable state to an alternate state in a catastrophic manner. Crucial stage of recruitment determination may shift from an early life history (e.g. larval) stage to another (e.g. juvenile) stage, and from one factor (e.g. food) to another (e.g. predation) with the regime shift. In this sub-session, observed and theoretical papers on recruitment dynamics and their underlying ecological processes of aquatic animals will be presented and discussed. |
