摘要
Ants due to their nesting habits are ideal for studying temporal fluctuations in trace metal accumulation changes in morphological traits as well as for assessing evolutionary processes and monitoring environmental Impact of metals derived from human activities Although metal pollution may affect basic ecological traits such as colony size and survival ants can be considered relatively resistant to metal pollution at least partly due to relatively high metal regulation efficiency At both polluted and unpolluted areas the body metal levels in ants vary considerably between species This observation and other experimental data suggest differences in metal regulation physiology however the physiological basis of these differences remains unknown It was shown that metal pollution may suppress the Immune defense systems which in turn could theoretically lead to a higher risk of infections Biodiversity studies are limited however the evidence for a clear negative influence of metal pollution on ant species diver
