Diplodon dunkerianus

Unknown

Overview

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

Diplodon dunkerianus faces severe population declines primarily due to water pollution from agricultural runoff and urban development in its freshwater habitats. Dam construction and river channelization have fragmented populations and altered the natural flow regimes essential for this mussel's reproductive cycle. Sedimentation from deforestation and intensive agriculture has degraded water quality, reducing oxygen levels and burying the substrate where these filter-feeders anchor themselves.

Threat summary

Habitat

This freshwater mussel inhabits clean, well-oxygenated rivers and streams with sandy or gravelly substrates in South America. It requires stable water flow and low sedimentation levels to maintain its filter-feeding lifestyle and successful reproduction.

Frequently asked questions

Why is Diplodon dunkerianus classified as Endangered?
Diplodon dunkerianus is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Diplodon dunkerianus faces severe population declines primarily due to water pollution from agricultural runoff and urban development in its freshwater habitats. Dam construction and river channelization have fragmented populations and altered the natural flow regimes essential for this mussel's reproductive cycle. Sedimentation from deforestation and intensive agriculture has degraded water quality, reducing oxygen levels and burying the substrate where these filter-feeders anchor themselves.
Where does Diplodon dunkerianus live?
Diplodon dunkerianus occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
