Peixe-anual
Austrolebias varzeae
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Austrolebias varzeae faces severe habitat degradation from agricultural expansion and urban development across its limited range in southern Brazil's coastal plains. The species' dependence on temporary wetlands makes it particularly vulnerable to hydrological changes from drainage projects and altered precipitation patterns. Water pollution from agricultural runoff and urban waste further compromises the quality of remaining breeding pools.
Habitat
This annual killifish inhabits temporary freshwater pools, seasonal wetlands, and shallow marshes in the coastal lowlands of Rio Grande do Sul, Brazil. The species requires ephemeral water bodies that fill during rainy seasons and dry completely during drought periods, allowing eggs to survive in dried sediment.
