Sunto
The different tolerance for high temperature (30°) among the young of two geographical races (Holland and Southern Italy) of Asellus aquaticus (L.) (Crust. Isop.) is evaluated. The young of the southern population exhibit a lower mortality rate than those of the northern population, which died before the 60th day of the experiment. The southern animals also exhibit an inverse relationship between mortality rate and body-size. In fact the survival rate of the young is greater than that of the adults.
