So I’m trying out these practice question for my upcoming test but can’t figure out the answer and can’t find the answers anywhere in the textbook.
What types of natural disturbance play a role in affecting species richness in plant
communities?  Does human caused disturbance mimic ‘natural’ disturbance?
2. What kinds of dispersal traits influence whether a species can colonize a plant
community?
3. Given the effects of disturbance on species richness in this old field community, how
should one manage a forest to maintain native species richness?
4. Can you predict the habitat (or niche) requirements are of exotic species based on
where you found them relative to native old field species?  How do the life history traits
(mode of reproduction, growth rate, amount of offspring produced, seed size) of exotic
species differ from that of native species
