Document Summary

Explain the main life history trait that differentiates stress-tolerant plants and ruderals and affects their fitness (limit:4-5 sentences): Focus your answer on the main life history trait. Less energy directed towards seed production because seeds have hard time germinating in stressful conditions. Enhance fitness, reproduce as much as you can. The main difference in the proportion of energy devoted to reproduction. Stress-tolerant plants live in growth limiting environments, so they increase their fitness by reducing the amount of energy used for seed production; seeds are energeticllay costly and are likely o have low survival in a stressful habitat. Rudereals are adapted to disturbance, thus mature plants cannot depend on long term survival.
