Sphagnum moss carbon sequestration research
Overview
An international research study published in the journal New Phytologist has identified the mechanisms by which Sphagnum mosses in peatlands facilitate carbon sequestration in water-saturated environments.
Researchers analyzed 20 Sphagnum species and four laboratory-grown clones, establishing a link between the chemical properties of cellular surfaces and photosynthetic performance. The findings indicate that species possessing a higher concentration of reactive chemical groups on their cell surfaces demonstrate greater CO2 assimilation.
While photosynthesis was maintained across all studied species under water-saturated conditions, responses varied significantly based on specific species and pH levels. For example, Sphagnum palustre L. exhibited a particularly stable response across a wide pH range. The study highlights the importance of these mosses, noting that while peatlands cover only 3% of the Earth's surface, they store nearly one-third of the planet's soil carbon.
