Elevated CO 2 Effects on Lichen Frequencies and Diversity Distributions in Free-Air CO 2 Enrichment (FACE) Station

Abstract

Carbon dioxides (CO2) concentration has become much higher every year and this has already become the global issue. Lichen is a symbiotic organism that is best known as the air pollution indicator. Based on its frequency and diversity distribution, the level of pollution that has been made can be determined. This research was conducted in UKM Fernarium Free Air Carbon Dioxides Enrichment Station (FACE Station) with lichen frequencies and diversities observed and analyzed statistically and graphically. Seven species of lichens were found at the sampling locations. Findings showed that there was significant relationship in lichen frequency and diversity distribution under elevated CO2 inside FACE Station with its surrounding.
