Heart rate and hemocyte number as stress indicators in disturbed hibernating vineyard snails, Helix pomatia

Furthermore, the assays demonstrate an increasing linear relation between rising temperature and frequency of heart pulsations (y = 1.01x − 2.1); but the results do not indicate a correlation between heartbeat frequency and the number of cells in circulation. Consequently, neither temperature nor heart frequency seems to influence the number of circulating cells in hibernating H. pomatia.
