Case Study- Environmental change leads to changes in a species Possums and sodium fluoroacetate resistance Possums‚ from populations with exposure to this vegetation‚ are particularly tolerant to fluoroacetate. However‚ the level of tolerance varies among the different populations of each species‚ depending on the degree to which the toxic plants were present in their microhabitat. The brush-tailed possum (T. vulpecula) from Western Australia was found to be nearly 150 times more resistant
