Cuatro Ciénegas (Mexico)
威脅瀕危物種: Arundo donax has been a major contributor to the loss of the endemic and threatened Rio Salado darter, Etheostoma segrex (Norris & Minckley 2002), which recent surveys deem to be near extinction (McGaugh, 2006).
降低本地生物多樣性: Because of its ability to inhabit shallow clear-water streams, Arundo donax could put the globally rare and unique stromatolites of the Cuatro Ciénegas ecosystems in jeopardy (McGaugh, 2006).
