Morphology and Identification

Riccia collata Na-Thalang is a thallose liverwort, meaning it grows in a flat, ribbon-like form without distinct stems or leaves. Its thallus is typically green, forming rosettes or mats on the ground or other substrates. One of its distinguishing features is the presence of

, which refers to the raised, elongated ridges or folds on the thallus surface. These ridges aid in water conduction and gas exchange, allowing the moss to thrive in diverse environments.

Global Distribution and Habitat

This remarkable moss has a widespread distribution, found on various continents, including Asia, Europe, and North America. It thrives in a range of habitats, from moist soil and rocks to disturbed areas like lawns, gardens, and even cracks in sidewalks. Riccia collata Na-Thalang is well-adapted to both natural and human-influenced environments, making it a resilient and versatile species.

Ecological Roles and Adaptations

Despite its small size, Riccia collata Na-Thalang plays vital roles in the ecosystems it inhabits. As a pioneer species, it helps stabilize and enrich soil, creating favorable conditions for other plants to establish themselves. Additionally, this moss serves as a food source and microhabitat for various invertebrates, contributing to biodiversity.
One of the remarkable adaptations of Riccia collata Na-Thalang is its ability to survive desiccation (drying out) and rapidly rehydrate when moisture becomes available. This trait, known as poikilohydry, allows the moss to thrive in environments with intermittent water availability, making it a true survivor.

Case Studies/Examples

In a recent study conducted in a urban park, researchers found that Riccia collata Na-Thalang played a crucial role in stabilizing soil and preventing erosion on disturbed slopes. Its presence also facilitated the establishment of other plant species, contributing to the overall ecosystem recovery.
