Overview

Theoretical analysis reveals that positive pairwise interactions do not guarantee positive net effects in multispecies guilds, suggesting that lower-quality mutualists can disrupt partner populations.

Key Points

To shift the conceptual focus from strictly pairwise mutualisms to multispecies guilds and assess how intraguild competition and partner quality variation shape population dynamics.
Synthesized ecological evidence on diffuse mutualisms and molecular findings demonstrating cryptic diversity within mutualist partnerships.
Developed path analytic models to evaluate population dynamics and net interaction outcomes in mutualisms comprising more than two species.
Demonstrated that positive pairwise interactions between mutualists do not necessarily translate into positive net interactions within multispecies assemblages.
Showed that intraguild competition for partners or external resources allows lower-quality mutualists to depress partner populations by displacing more beneficial mutualists.
