Drack J. M. E., Vázquez D. P., Morphological response of a cactus to cement dust pollution, Ecotoxicology and Environmental Safety, 2018, 148:571-577, doi: 10.1016/j.ecoenv.2017.10.046
The study of the response of Tephrocactus aoracanthus to cement dust combines field observations, transplanting between sites and controlled dust application. It compares spines, segment diameter and fresh and dry mass. The individual experimental setups yielded different responses in morphological traits.
