| Research Abstract |
This study examined "population units" with long-term data on salmonid fish, considering population dynamics, genetic structure, and life history variation. Microsatellite DNA analysis indicated genetic homogeneity for stream groups within 5-10km. However, demographic independency was suggested even among genetically non-divergent groups. In addition, despite significant variations in life history traits among streams, no geographic cluster was observed. This study suggested that population units can vary depending on the entities we focus.
