Abstract

The focus of this study was to gain further understanding on the thermodynamic behaviour of the dew and non-dew harvesting spines of cacti. Four species of cacti were chosen, three that were known to harvest dew on their spines and one that does not. The temperature gradient of the spines of the mos...
