Myriocolea irrorata

Unknown

Overview

Colura irrorata is a species of liverwort in family Lejeuneaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss. The species was previously known as Myriocolea irrorata, but was transferred to Colura in 2012 following a phylogenetic analysis of nuclear and plastid molecular markers and a reinterpretation of morphological characters.

Myriocolea irrorata faces severe threats from habitat destruction due to deforestation and agricultural expansion within its extremely limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human activities. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this species requires for survival.

Threat summary

Habitat

Myriocolea irrorata inhabits specialized microhabitats within tropical forest ecosystems, typically found in areas with specific moisture and substrate requirements. The species appears to be restricted to very localized conditions that support its particular ecological needs.

Frequently asked questions

Why is Myriocolea irrorata classified as Critically Endangered?
Myriocolea irrorata is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Myriocolea irrorata faces severe threats from habitat destruction due to deforestation and agricultural expansion within its extremely limited range. The species' restricted distribution makes it particularly vulnerable to localized environmental changes and human activities. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this species requires for survival.
Where does Myriocolea irrorata live?
Myriocolea irrorata occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
