Extirpation of prairie canines can also add to regional and native biodiversity decline, increased seed depredation, plus the institution and spread of invasive shrubs.[23] Burrowing rodents could eat the fruiting bodies of fungi and distribute spores via their feces, therefore allowing for the fungi to disperse and kind symbiotic relationships Together with the roots of crops (which commonly are not able to prosper with no them).
