Results of the short term experiments for the Pyrenean ( T. fonti ) and coastal ( T. ferreri ) species of Troglocharinus. A) Example graph of the lower thermal limit (LTL) experiment. The arrow marks the point at which the specimen froze (i.e. the supercooling point), with the sudden liberation of latent (or crystallization) heat, considered to be the LTL. B) Upper thermal limit (UTL). C) LTL. Columns, average temperature at which specimens died, with standard deviation.
