Process and seasonal context
- Definition
- Sorting of stream species by climbing ability and barriers along steep Hawaiian streams.
- Drivers
- streamflow; floods; ocean currents; plume cues; barriers
- Inputs
- larvae; juveniles; organic matter; water
- Outputs
- recruitment; dispersal; subsidies; longitudinal zonation
- Spatial scales
- headwater → stream → estuary → ocean
- Temporal scales
- hours → months → generations
- Validity and limits
- Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
