Hypsolebias radiseriatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hypsolebias radiseriatus faces severe threats from habitat destruction as its temporary pool environments are drained for agricultural expansion 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 domestic waste further degrades the quality of remaining breeding pools, while the introduction of non-native fish species poses additional predation pressure on this endemic killifish.
Habitat
This endemic killifish inhabits temporary pools and seasonal wetlands in the Brazilian Cerrado savanna, particularly in areas with sandy soils that retain water during the rainy season. The species requires shallow, ephemeral water bodies that form during seasonal flooding and gradually dry out, completing its entire life cycle within these brief aquatic windows.
