Stygobromus gradyi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Stygobromus gradyi faces significant threats from groundwater contamination and depletion due to agricultural runoff and urban development in its limited range. The species' obligate dependence on pristine groundwater systems makes it extremely vulnerable to pollution from pesticides, fertilizers, and industrial chemicals that can infiltrate aquifer systems. Water table lowering from excessive pumping for irrigation and municipal use directly reduces available habitat for this subterranean amphipod.
Habitat
Stygobromus gradyi inhabits groundwater systems and underground aquifers in limestone karst regions. This obligate stygobiont species is restricted to subterranean freshwater environments with stable temperatures and high water quality.
