Physical stress modifies top-down and bottom-up forcing on plant growth and reproduction in a coastal ecosystem.

abstract：:Interactions between grazers and autotrophs are complex, including both top-down consumptive and bottom-up facilitative effects of grazers. Thus, in addition to consuming autotrophs, herbivores can also enhance autotroph biomass by recycling limiting nutrients, thereby increasing nutrient availability. Here, we evalua...
