Holoscolex dossantosi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Holoscolex dossantosi faces severe threats from agricultural expansion and urbanization within its limited range in southeastern Brazil. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as earthworm populations require continuous soil connectivity for dispersal and genetic exchange. Intensive farming practices, including heavy pesticide use and soil compaction from machinery, directly degrade the soil ecosystems this endemic earthworm depends upon for survival.
Habitat
This endemic earthworm inhabits the rich, organic soils of Atlantic Forest remnants and adjacent agricultural areas in southeastern Brazil. The species requires well-drained, humus-rich soils with stable moisture levels and minimal chemical contamination.
