A compromise to high species diversity in space is to maximize species diversity in time; this is best accomplished by ensuring that a given field is subjected to diverse rotational cro

Traits conferring strong competition such as enhanced rates of allelopathic chemical production or those produced by new plant—microbial interactions formed when exotic plants enter new communities can be negated by biological control mechanisms.

Currently, it is not possible to make generalizations about which mechanism is the most important because of the extreme lack of information for most plant invasions. To understand the nature of the relationship between diversity an
