Functional loss in herbivores drives runaway expansion of weedy algae in a near-future ocean
The ability of a community to absorb environmental change without undergoing structural modification is a hallmark of ecological resistance. The recognition that species interactions can stabilize community processes has led to the idea that the effects of climate change may be less than what most c...

The ability of a community to absorb environmental change without undergoing structural modification is a hallmark of ecological resistance.

Using a six-month mesocosm experiment, we show that increasing per capita herbivory by gastropods absorbs the boosted effects of CO₂ enrichment on algal production in temperate systems of weak to moderate herbivory.
