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 re-search 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 li-chens 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.
Highlights
Lichens, the product of a symbiotic relationship between a fungus and at least one photosynthetic algae or cyanobacterium, are widely used as bio-indicators of air pollution and environmental change, both at cellular and the population or community level [1]
Due to the unique biology and their sensitivity to pollutants, lichens respond to variations in atmospheric composition and may be a useful measure for monitoring environmental quality
Lichens are responding to global warming and some long-term monitoring programmes
Summary
The product of a symbiotic relationship between a fungus (mycobiont) and at least one photosynthetic algae or cyanobacterium (photobiont), are widely used as bio-indicators of air pollution and environmental change, both at cellular and the population or community level [1]. (2016) Elevated CO2 Effects on Lichen Frequencies and Diversity Distributions in Free-Air CO2 Enrichment (FACE) Station. The inability to regulate water loss limits the possible responses to CO2 as compared to those of vascular plants, the trade-offs related to, for instance, nitrogen allocation occur here just as much. This could be the case for those epiphytes that grow closely attached to canopy soil or directly on living branches. The objectives of this research were to compare the lichen diversity inside and outside Free-Air CO2 Enrichments Station (FACE) and to analyze the distribution of identified lichen species [4] [5]. Three different distances (20 m, 50 m and 80 m approximately) were selected to depict the effects of CO2 on lichen distribution (Figure 1)
