Notodiaptomus dubius

Unknown

Overview

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

Notodiaptomus dubius faces severe pressure from agricultural expansion and urban development that degrades and fragments its freshwater habitat. Water pollution from agricultural runoff, particularly pesticides and fertilizers, directly impacts this planktonic copepod's survival and reproduction. Climate change-induced alterations to precipitation patterns and temperature regimes further threaten the delicate aquatic ecosystems this species depends upon.

Threat summary

Habitat

Notodiaptomus dubius inhabits freshwater lakes, ponds, and slow-moving rivers in South America, particularly in temperate and subtropical regions. This planktonic copepod thrives in well-oxygenated waters with moderate nutrient levels and stable temperature regimes.
