Overview

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

Gammarus hyalelloides faces severe threats from water pollution and habitat degradation in its limited freshwater range. Agricultural runoff containing pesticides and fertilizers has contaminated many of the small streams and springs where this amphipod occurs. Urban development and water extraction for human use have further reduced available habitat, while climate change threatens to alter the specific water temperature and chemistry conditions this species requires.

Threat summary

Habitat

This freshwater amphipod inhabits small streams, springs, and shallow groundwater systems with specific water chemistry requirements. It typically occurs in cool, well-oxygenated waters with stable temperatures and low pollution levels.
