Chroothece rupestris

Local name: geléskorpa

Unknown

Overview

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

Chroothece rupestris faces significant threats from air pollution and acid rain, which alter the chemical composition of its rock substrates and disrupt the delicate pH balance required for survival. Urban development and quarrying activities directly destroy the specific rock face habitats where this cyanobacterium forms its characteristic colonies. Climate change poses additional risks through altered precipitation patterns and temperature fluctuations that affect the moisture regimes essential for this species' photosynthetic processes.

Threat summary

Habitat

Chroothece rupestris inhabits exposed rock faces, cliff surfaces, and stone walls in temperate regions, forming distinctive dark crusts on calcareous and siliceous substrates. This cyanobacterium requires specific moisture conditions and pH levels, typically colonizing north-facing or shaded rock surfaces that maintain consistent humidity levels.
