This study shows that interspecies interaction strength determines whether communities or species are the units of selection during microbial coalescence.

The paper shows that complex ecosystems become unstable when resource consumption deviates from niche ranges, leading to alternative states and species extinction.

The paper shows that invasion success and impacts in microbial communities depend on dynamics, interaction strength, and diversity, with more fluctuating and diverse communities being more invasible and having larger ecological effects.

The paper shows that ecosystem stability depends on diversity differences between trophic levels rather than absolute diversity, with stability increasing as diversity differences grow.
