Gammarus acherondytes

Unknown

Overview

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

Gammarus acherondytes faces severe threats from groundwater pollution and aquifer depletion due to agricultural runoff and urban development in its limited range. The species' restriction to specific cave and groundwater systems makes it extremely vulnerable to water quality changes and hydrological disruption. Climate change poses additional risks through altered precipitation patterns that could affect groundwater recharge rates and cave hydrology.

Threat summary

Habitat

This amphipod is endemic to subterranean freshwater environments, specifically cave streams and groundwater systems in karst regions. It inhabits the phreatic zone of limestone caves where it depends on stable water chemistry and consistent flow patterns.

Frequently asked questions

Why is Gammarus acherondytes classified as Endangered?
Gammarus acherondytes is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Gammarus acherondytes faces severe threats from groundwater pollution and aquifer depletion due to agricultural runoff and urban development in its limited range. The species' restriction to specific cave and groundwater systems makes it extremely vulnerable to water quality changes and hydrological disruption. Climate change poses additional risks through altered precipitation patterns that could affect groundwater recharge rates and cave hydrology.
Where does Gammarus acherondytes live?
Gammarus acherondytes occurs in Canada, and United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Gammarus acherondytes?
The main threats to Gammarus acherondytes are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
