Abstract Climate-driven shifts in herbivores, temperature and nutrient runoff threaten coastal ecosystem resilience. However, our understanding of ecological resilience, particularly for foundation species, remains limited due to a rarity field experiments that are conducted across appropriate spatial temporal scales investigate multiple stressors. This study aimed evaluate the resilience widespread tropical marine plant (turtlegrass) disturbances its geographic range how this is impacted by environmental gradients (a)biotic factors. We assessed (i.e. recovery) turtlegrass simulated disturbance (complete above- belowground biomass removal) over year. Contrary temperate studies, higher generally enhanced seagrass recovery. While nutrients light availability had minimal impact, combined high levels herbivore grazing (meso megaherbivore) reduced aboveground Our results suggest some especially cooler subtropical waters, may initially increase with warming.

ABSTRACT Climate‐driven shifts in herbivores, temperature, and nutrient runoff threaten coastal ecosystem resilience. However, ecological resilience, particularly for foundation species, remains poorly understood due to the scarcity of field experiments conducted across appropriate spatial temporal scales that investigate multiple stressors. This study evaluates resilience a widespread tropical marine plant (turtlegrass) disturbances its geographic range examines how environmental gradients (a)biotic factors influence recovery. We assessed turtlegrass by following recovery rates year after simulated pulse disturbance (complete above‐ belowground biomass removal). Contrary studies temperate areas, higher temperature generally enhanced seagrass While nutrients had minimal individual effects, they reduced aboveground when combined with high levels herbivore grazing (meso megaherbivore). Belowground was also affected (megaherbivores only). Light availability effects. Our results suggest some cooler subtropical waters, may initially benefit from warming. continuing supply changes pressure ultimately serve compromise
