On the species-pool hypothesis and on the quasi-neutral concept of plant community diversity


5. Conclusions

5.1. According to the results from studying a broad variety of Estonian herbaceous communities (4.11) the question in 1.14 should be answered as:selection from a regional species pool into an actual species pool and selection from actual species pool into a microsite are mostlyrandom and neutral processesand they are not directed significantly by interspecific competition.

5.2. Yet, the formation of a diversity pattern should be called aquasi-neutral process,mainly because the exclusion of species from communities due to asymmetric light competition is common during succession (when taller species outcompete shorter ones).
