Stygobromus hadenoecus

Unknown

Overview

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

Stygobromus hadenoecus faces severe threats from groundwater contamination and aquifer depletion due to agricultural runoff and urban development in its limited Kentucky range. The species' obligate cave-dwelling nature makes it extremely vulnerable to water quality changes, as pollutants can persist in the isolated groundwater systems for decades. Climate change poses additional risks through altered precipitation patterns that could affect groundwater recharge rates and cave hydrology.

Threat summary

Habitat

This obligate cave-dwelling amphipod inhabits groundwater-fed pools and streams within limestone cave systems in Kentucky. The species requires stable, cool water temperatures and high water quality typical of pristine karst aquifer environments.
