Warm adaptation

Paleotemperature might be reconstructed in ancient sediments through biomarker signals if cold-adapted and warm-adapted organisms produced distinctive lipids. The best-known example of such a signal is the long-chain ketones produced by haptophytes that carry patterns of unsaturation determined by sea-surface temperature (Brassell et al., 1986). 

It is not known whether such natural cryoprotectants occur widely distributed among animal species. However, a relevant experiment was conducted with brain slices, from warm-adapted and hibernating hamsters, before and after freezing (92). Tissue slices from the hibernating hamster exhibited higher than normal oxygen consumption rates after freezing. This result did not occur with slices from the warm-adapted...
