A new study explores the coevolving web of life as a network, revealing counterintuitive results on direct and indirect effects within large webs of interacting species. The findings suggest that strong coevolutionary selection between partners increases the importance of indirect effects on overall evolution.
Researchers found that indirect effects of coevolution have a greater impact on complex biological communities than direct interactions. This is particularly concerning for species-rich networks, which are slow to adapt to rapid environmental changes and may face higher extinction risks.
