Anticipating the response of the Brazilian giant earthworm (Rhinodrilus alatus) to climate change: implications for its traditional use

摘要: Our understanding of the impacts ongoing global warming on terrestrial species has increased significantly during last several years, but how climatic change affected, and will affect, distribution earthworms remains largely unknown. We used climate niche modeling to model current giant earthworm Rhinodrilus alatus - an endemic Cerrado Domain in Brazil, which is traditionally harvested commercialized for fishing bait. R. sensitive environmental changes because climate, synergy with soil attributes, determine its annual reproductive cycle distribution. The paleoclimatic reconstructions predict important geographical shifts from LGM (~21,000 yBp) present potential alatus: range expansion, fragmentation, shrinkage core area. Further, 2070 scenarios substantial shrink losses stable areas. results indicate that not only affect extent distribution, also promote significant fragmentation a shift outside currently recognized boundaries. In this context, populations would decline traditional harvesting collapse, requiring immediate implementation management conservation measures economically sustainable alternatives local community.
