Climate change is a serious threat, and it is necessary to prepare for the future climate conditions of grazing areas. Dung beetle species can help mitigate global warming by contributing to intense nutrient cycling and reduction in greenhouse gas emissions caused by cattle farming. Additionally, dung beetles increase soil quality through bioturbation and reduce nematodes and hematophagous flies’ abundance in grasslands areas. There are several dung beetle species inhabiting South American pastures, however, the effects of climate change on their spatial distribution are still unknown. Here, we aimed to predict the potential effects of future climate change on the geographical spatial distribution of the four most important (“key”) pastureland dung beetle species that are native to South America. We used niche-based models and future climate simulations to predict species distribution through time. Our findings show radical reduction in the spatial range of dung beetle species, especially in recently opened areas, e.g., the Amazon region. We suggest that the consequences of these species’ spatial retraction will be correlated with ecosystem services depletion under future climate conditions, urgently necessitating pasture restoration and parasite control, as the introduction of new alien species is not encouraged.
