The presence of adult barnacles, however, did not protect developing recruits from canopy whiplash effects. By understanding the contrasting influences that intertidal algal canopies have on understory abiotic conditions and barnacle recruitment,
our ability to predict net canopy effects depending on the relative degree of physiological (e.g., high vs. low intertidal
zone) and physical (e.g., sheltered vs. exposed shores) stresses should increase
