Heat tolerance of porcelain crabs. Upper thermal tolerance limits (LT50 (°C)) of congeneric porcelain crabs (genus Petrolisthes) native to eastern Pacific habitats in California, Chile, the northern Gulf of California, and Panama and occurring at different heights along the subtidal-to-intertidal gradient. Each symbol represents a different species of crab. B. Thermal tolerance versus maximal habitat temperature, with a line of unity given to show the proximity of current habitat temperatures to lethal temperatures. Hatched symbol represents P. cinctipes. The R2 value for the regression line for all species is given. Data are from [10].
