Of 49 species compared quantitatively, only four species changed significantly over 3 yr, including two southern species (the snail Pseudomelatoma torosa, which increased, and the limpet Fissurella volcano, which decreased), and two cosmopolitan species (the snail Homalopoma luridum, which decreased, and the limpet Lottia asmi, which increased).
