Glossoscolex riograndensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Glossoscolex riograndensis faces severe habitat degradation from agricultural expansion and urbanization across its limited range in southern Brazil. The species' specialized soil requirements make it particularly vulnerable to land-use changes that alter soil chemistry and structure. Pollution from agricultural runoff and industrial activities further threatens the earthworm's sensitive ecosystem, while climate change may be shifting suitable habitat conditions beyond the species' adaptive capacity.
Habitat
This large earthworm species inhabits specific soil types in the Atlantic Forest region of Rio Grande do Sul, Brazil, requiring well-drained, organic-rich soils with particular moisture and pH conditions. The species is closely associated with native forest floor ecosystems where it plays a crucial role in soil formation and nutrient cycling.
