Monolistra bolei

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Monolistra bolei faces severe threats from groundwater pollution and habitat degradation in its limited cave systems. The species' restricted distribution to specific underground aquatic environments makes it extremely vulnerable to water quality changes from agricultural runoff and urban development. Cave disturbance from human activities and potential hydrological alterations pose additional risks to this endemic isopod's survival.

Threat summary

Habitat

Monolistra bolei inhabits underground aquatic environments, specifically cave systems and subterranean waters in karst landscapes. This endemic isopod is restricted to groundwater-fed cave pools and underground streams with specific water chemistry requirements.
