(Altieri, 1999). Intentionally mixing plant species will create
new habitats for associated species, mainly when the structure
of the system is modified (introduction of trees, for instance).
In sole crop systems, the mutually beneficial functions and
natural subsidies that lend stability and sustainability to natural
systems are usually destroyed and require energy subsidies.
According to Hobbs andMorton (1999), the stability and
sustainability of managed systems could be increased by replacing
external energy subsidies with the mutually beneficial
functions found in nature through biodiversity. Hence, multispecies
systems might or might not improve productivity, but
might improve sustainability by improving the ability to resist
or rebound in the face of disruptive effects, i.e. resilience
