PLSC 213 Lecture Notes - Lecture 19: Ruderal Species, Secondary Succession, Species Pool
Document Summary
Processes that produce these assemblages termed assembly rules . In a community with lots of open space and open ground there will be a lot of species growth that come from the seed bank that grow fast. Can also be viewed as ecological lters that eliminate species from the regional species pool that cannot survive at the site. Progressive change in the dominant species in a community. Once dominant species do not regain dominance unless community resort by disturbance. More nutrients in the system is within the plant biomass rather then within in the soil. A tropical forest has all nutrients in the plant tissue. Ruderal species will outcompete the other species. Primary: succession on raw soil parent material. Secondary: succession on existing soil and generally some in situ surviving propagules. Plant existing that survived the disturbance, can often be very fast.
