Body Size of the Monomorphic Ant Lasius niger: Young Colonies along a Metal Pollution Gradient
Table 1
The results of linear regression of statistics describing the body size distribution of Lasius niger workers versus pollution level. Five independent analyses were done. None of the statistics were significantly correlated with the metal pollution gradient.
