CRCritically Endangered

Hypsolebias gilbertobrasili

Unknown

Overview

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

Hypsolebias gilbertobrasili faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted range within Brazil's Cerrado savanna. The species' dependence on temporary pools and seasonal wetlands makes it particularly vulnerable to hydrological changes from dam construction and water extraction. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate timing of breeding cycles tied to seasonal flooding.
