Melanorivulus ubirajarai

Unknown

Overview

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

Melanorivulus ubirajarai faces severe pressure from agricultural expansion and cattle ranching activities that degrade and fragment its freshwater habitats in Brazil's Cerrado region. Urban development and water extraction for irrigation further reduce available breeding sites, while pollution from agricultural runoff degrades water quality in remaining streams and pools.

Threat summary

Habitat
