2. Inventory data which may be appropriate for developing
relationships, develop testable hypotheses, and analyze data.
3. Select relationships which suggest potential limiting
conditions(i.e., significant changes in dependent variable as a
function of independent variable; Fig. 1).
4. Identify data needs (fill gaps with professional judgment until
empirical relationships can be developed).
a. List data needs for important variables and life history phases.
b. Propose hypotheses relating life stage response to variables.
c. Test hypotheses, develop relationships.
III. Develop, verify, and validate relationships and methods for quantifying
species response to flow alterations. Focus on limiting variables and
limiting life stages; document assumptions.
A. Life stage response vs. flow (Fig. 2A).
6. Life stage response vs. variable (Fig. 26).
C. Variable vs. flow (Fig. 2C).
