Stygobromus hubbsi

Unknown

Overview

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

Stygobromus hubbsi faces significant threats from groundwater contamination and aquifer 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 persist in aquifers for decades. Water table lowering from excessive pumping for irrigation and municipal use directly reduces available habitat, while climate change may alter groundwater recharge patterns in its already restricted distribution.

Threat summary

Habitat

Stygobromus hubbsi inhabits groundwater systems including caves, springs, and interstitial spaces within aquifers in limestone karst terrain. This obligate stygobiont requires pristine, oxygen-rich groundwater with stable temperatures and minimal chemical contamination.
