Objective(s): To study the freezing tolerant larvae of Gynaephora groenlandica (the arctic woolly-bear caterpillars) to examine other potential adaptations that may be crucial in mediating freezing tolerance but have eluded previous detection in other systems using other experimental techniques;

Project Description: Arctic arthropod communities are extremely sensitive to changes in their physical environment and their composition reflects trace elements in the atmosphere or minor fluctuations in termperature. This project is part of a larger, long-term project involving a survey of arctic arthropods which will ultimately provide a monitoring system for global climatic changes and indicate levels of pollutants.
