Document Summary
Glacier lily flowering plants seem to do best where the soil surface is very rocky. Life history: iteroparous, long resource accumulation phase in an underground corm. What factors about soil may influence on success of seeds. Deeper soil areas will contain more moisture compared to the rocky. Buried in organic soil made it, others not. Results of experiment suggest the opposite of what we saw: should find more plants away from thin soil around rock outcrops. How to quantify gopher activity leave cores of soil in the spring. Few seeds that reach moist, deep-soil area are more likely to survive and produce seedlings. Most seeds are produced in rocky areas and fall there but most die. But seedlings that get established in deep-soil have a risk to be under predation of gopher. Desiccation due to abiotic conditions and stress, cant happen a lot, because flowers are there. Why no elaisome dispersal is a disadvantage.
