Trophic complementarity drives the biodiversityecosystem
... By changing a21 and c22 between 0 and 1, we can vary the values of qC and qP independently. The system is then analysed to see if the conditions for coexistence of the two consumers and transgressive overyielding are satisfied. We find that both resource-use and predation complementarity are importa ...

A metaanalysis of biotic resistance to exotic plant invasions

Although resistance is a well-accepted phenomenon, less clear are the processes that contribute most to it, and whether those processes are strong enough to completely repel invaders ...
