Daphnia jollyi

Unknown

Overview

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

Daphnia jollyi faces severe threats from habitat degradation in its limited freshwater environments, particularly through water pollution and eutrophication that alter the delicate chemical balance required for its survival. Urban development and agricultural runoff in its restricted range have led to increased sedimentation and nutrient loading, creating conditions unsuitable for this specialized microcrustacean. Climate change poses additional risks through altered precipitation patterns and temperature fluctuations that can disrupt the species' reproductive cycles and food web dynamics.
