Hypsolebias trilineatus

Unknown

Overview

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

Hypsolebias trilineatus faces severe habitat degradation from agricultural expansion and cattle ranching in Brazil's Cerrado savanna. The species' dependence on seasonal temporary pools makes it extremely vulnerable to hydrological changes from land conversion and climate variability. Water pollution from agricultural runoff and livestock activities further compromises the quality of its breeding habitats.
