Various methods have been developed to monitor environmental quality, including biomonitoring using lichen. In this paper, a total of 143 previous studies from the last decade were analyzed to gain insight into current practices, progress, and challenges. Content analysis was employed to systematically characterize and classify the existing biomonitoring using lichen studies into several groups based on research area and scope. Various aspects of current biomonitoring applications using lichen … Read more... 

Lichen is a well-documented useful biological indicator for monitoring air pollution using various methods such as the biodiversity of lichens. However, the use of lichen biodiversity to estimate air pollution levels in industrial areas, particularly in Malaysia, is still weak, and the determinants of its diversity are unknown. As a result, the purpose of this research is to analyse air pollution in Malaysia’s industrial urban area using the lichen biodiversity index and its determining factor. … Read more... 

A total of 12 species of lichens was recorded from the coastal areas of Teluk Nipah, Pulau Pangkor, Perak. The species are Buellia curatellae Malme, Dirinaria confluens (Fr.) D.D.

In Malaysia, air pollution still measured using instrumental approach. Hence, this study used lichen as biological indicator to assess air pollution. Study has been conducted in four different locations which are Rumah Tumbuhan, UKM (Control station), Section 51 Industrial Area, Petaling Jaya, Spring Crest Industrial Area, Batu Caves and Nilai Industrial Area, Negeri Sembilan. This study used lichen Dirinaria sp.; an endemic species of tropical country; as the biological indicator. Heavy metal concentrations … Read more... 

Floristic study on lichens from Khanas natural reserve and Bayinbulak grassland was carried out. Lichen genus Xylographa (Fr.) Fr. was found as new recorded genus to China, one species, Xylographa parallela (Ach.) Fr. was found in this genus. The description of the genus and species including its anatomy, chemistry, and ecology with photographs is presented in this paper. Keywords： Khanas Bayinbulak grassland Lichen New record Xylographa paralela. [in Chinese with English abstract; … Read more...
