Thermal tolerance patterns of a carabid beetle sampled along invasion and altitudinal gradients at a sub-Antarctic island
Insects sampled along the invasion gradient were not characterized by an increased thermal tolerance.
Significant differences in the ability to recover from thermal stress were found among populations.
Cold tolerance was not always the highest in organisms sampled at higher altitude.
Insects with relatively high cold tolerance were often relatively sensitive to heat exposure and vice versa.
Insects could recover from short exposure to −5 °C and 35 °C, but few could recover from short exposure to −8 °C or 38 °C.
