Abstract Uplifting of a portion of an intertidal rock bench by the “Milrow” underground nuclear test at Amchitka Island, Alaska affected algal abundance, species composition, and zonation. Parts of the populations of 8 species died off, primarily in the Hedophyllum sessile zone, and mostly within the first 6 months after the disturbance. The center of abundance of these species shifted seaward. Fucus distichus, a species of the upper intertidal, appeared in the area and recolonized a portion of the H. sessile zone. The observations indicate that intertidal algal communities at Amchitka Island are very sensitive to positive elevation changes.
