Cross-domain structural pattern
Proliferation limitations determine spreading dynamics. Growth arrest causes superlinear spreading at reduced rate. Pressure-limited growth produces linear constant-speed spreading. Nutrient-limited growth exhibits phase transition: superlinear when nutrient supply is high, sublinear when depleted. Nutrient supply and conversion efficiency determine phase boundary. Spreading rate distinguishes dominant limitation type.

Parameter uncertainty propagates through dynamics affecting predictions. Sensitivity analysis reveals which parameters control outcomes versus which have negligible impact.
