Dataset for "Limited contamination by trace metals in city colonies of the ant Temnothorax nylanderi"

This file contains the data used for the article "Limited contamination by trace metals in city colonies of the ant Temnothorax nylanderi". In this study we assessed whether city colonies of the ant Temnothorax nylanderi differed form forest colonies in their trace metal contamination, and we tested whether larger colonies tolerate better pollution with a lower level of contamination. We collected ant colonies and soil from five city parks in Paris and five forests around Paris, and we measured the concentration of five trace metals (cadmium, copper, iron, lead and zinc).
