Hypsolebias notatus

Unknown

Overview

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

Hypsolebias notatus faces severe threats from habitat destruction as its temporary pool habitats in the Brazilian Cerrado are converted to agriculture and urban development. The species' dependence on seasonal rainfall patterns makes it particularly vulnerable to climate change-induced alterations in precipitation cycles. Water pollution from agricultural runoff and cattle ranching activities further degrades the quality of remaining breeding pools.

Threat summary
