Abstract Changes in temperature and precipitation patterns, along with extreme weather events, have altered natural habitats, contributing to species extinctions ecosystem fragmentation worldwide. Climate change can exacerbate disturbances trigger biological invasions that threaten native species. Here, we used ecological niche models predict the future distribution of five invasive earthworm (Amynthas corticis, Amynthas gracilis, Dichogaster bolaui, Polypheretima elongata, Pontoscolex corethrurus) within Doce River Basin (DRB), Brazil. We also assessed impact Fundão dam collapse on suitability changes using a vegetation index as proxy for forest cover. found that, despite being invasive, most are expected experience contractions suitable climate areas, losses reaching up 66% P. elongata. Only D. bolaui is predicted retain areas across entire study area all scenarios. The results indicated exacerbated reductions forested regions, post-collapse approximately 33% smaller than pre-collapse conditions. Nevertheless, southeastern portion DRB projected conditions species, indicating high potential this region. These findings highlight need targeted management strategies prevent dominance restore buffer against impacts control earthworms. Ecological restoration efforts, alongside integration environmental monitoring modeling, crucial mitigating biodiversity loss enhancing resilience invasion by alien earthworms face change.
