Hypsolebias macaubensis

Unknown

Overview

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

Hypsolebias macaubensis faces severe threats from habitat degradation in its restricted range within the Cerrado savanna of Brazil. Agricultural expansion and cattle ranching have significantly altered the seasonal wetland systems this killifish depends upon for breeding. Water pollution from agricultural runoff and altered hydrological patterns due to land conversion pose additional pressures on the remaining populations.

Threat summary

Habitat

This annual killifish inhabits temporary pools and seasonal wetlands within the Cerrado savanna ecosystem of central Brazil. The species depends on ephemeral water bodies that fill during the rainy season and dry completely during drought periods, requiring specialized adaptations for survival in these highly variable aquatic environments.
