Coping with cold: natural solutions: symposium and annual general meeting of society for low temperature biology.

The Symposium explored the diversity of adaptations to cold in a wide range of organisms from microbes to vertebrate animals and highlighted the characteristics of the many and varied adaptations to cold at ecological, physiological, biochemical and molecular levels. Emphasis was placed on the environmental context to aid understanding of the cryobiology. Discussion of the various strategies involved in nature focussed on the potential to apply particular features of natural systems for Man's benefit. A summary of the oral and poster presentations made at the Symposium is given below followed by selected abstracts and three papers arising from the meeting

DSC studies of freezing in terrestrial enchytraeids (Annelida: oligochaeta).

Specimens of six enchytraeid species from a wide range of terrestrial habitats were cooled to -25 degree C and rewarmed at 1 degree C/min and their cryobiological features measured by DSC. All were freezing intolerant, supercooling on average to c.-9 degree C. The quantity of frozen (osmotically active) water, calculated from the melt endotherm, varied considerably from 17 to 62% depending on the species and formed three groups. It is suggested that variation in the amount of water frozen in the worms reflects the acclimatisation of these species to the environmental conditions of their habitats.
