Melanorivulus karaja

Unknown

Overview

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

Melanorivulus karaja faces significant pressure from agricultural expansion and cattle ranching activities that degrade its freshwater habitats in the Brazilian Cerrado. Urban development and water extraction for irrigation further fragment and pollute the small streams and seasonal pools this species depends on. Climate change poses an additional threat through altered precipitation patterns that could dry up critical breeding habitats during reproductive seasons.

Threat summary

Habitat
