Overview

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

Stygobromus pecki faces severe threats from groundwater contamination and habitat degradation within its extremely limited cave system range. Urban development and agricultural runoff in the surrounding watershed directly impact the delicate groundwater chemistry essential for this obligate cave amphipod's survival. The species' restriction to specific cave environments makes it particularly vulnerable to any changes in water quality or flow patterns.

Threat summary

Habitat

This obligate cave-dwelling amphipod inhabits groundwater systems and underground streams within limestone cave networks. The species requires pristine, oxygen-rich groundwater with stable temperatures and specific chemical conditions found only in undisturbed karst aquifer systems.
