The Mammillaria cactus M. guerreronis occurs naturally only in the state of Guerrero in Mexico, and the smallness of its range makes it especially vulnerable to extinction. The traditional single-species approach to conservation emphasizes the need to focus on individual species most at risk, like M. guerreronis, but recently, conservationists have argued that an ecosystem-based approach that incorporates the many interactions between the climate, terrain, and various species of a given geographical area may lead to better outcomes for all the species in a given location. An ecosystem-based approach to the conservation of M. guerreronis could thus __________

identify conservation strategies that may not be exclusively aimed at protecting M. guerreronis but that benefit the species nonetheless.

lead to a better understanding of how the distribution of Mammillaria species throughout Mexico has affected their survival.

be unable to evaluate whether M. guerreronis would be capable of surviving in habitats outside of Guerrero.
