Abbas A., Guo S.-Y., Ababaikeli G., Abdulla A. & Xahidin H. (2015): Diploschistes xinjiangensis, a new saxicolous lichen from northwest China - Mycotaxon, 129(2): 465-471

Diploschistes xinjiangensis from Xinjiang in northwest China is described as new to science. The species is characterized by the thick bluish gray thallus, asci with eight large ellipsoid ascospores, and the presence of diploschistesic and lecanoric acids. It grows on rock in the semiarid region at elevations of ca. 1700 m. ITS rDNA sequence analyses support the taxonomic distinctness of this species. Key words — Asia, biodiversity, Graphidaceae, Ostropales, taxonomy. Read more...

Abas A., Sulaiman N., Adnan N.R., Aziz S.A. & Nawang W.N.S.W. (2019): Using Lichen (Dirinaria sp.) as Bio-Indicator for Airborne Heavy Metal at Selected Industrial Areas in Malaysia - Environment Asia, 12(3): 85–90

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...

Background: Indoor air quality (IAQ) is a concern in kindergartens as children spend much of their time there. Yet, there is a shortage of biological indicators needed for assessing IAQ. Thus, this study evaluated IAQ using transplanted lichen Usnea misaminensis as a biological indicator. Methods: Lichen samples, collected from Bukit Larut, Perak, Malaysia, were exposed to indoor and outdoor environments in an urban area (Ummi Aiman Kindergarten) and a rural area (Ummi Qaseh Pelangi Kindergarten) … Read more...

Abas A., Awang A. & Aiyub K. (2019): Analysis of heavy metal concentration using transplanted lichen Usnea misaminensis at Kota Kinabalu, Sabah (Malaysia) - Applied Ecology and Environmental Research, 18(1): 1175–1182

Heavy metals were emitted from motor vehicles and industries as part of the effects of rapid urbanization. This study aims to measure the heavy metal concentrations (Cu, Fe, Zn, Pb, Mn, Cr) at Kota Kinabalu, Sabah using transplanted lichen. Samples of Usnea misaminensis were transplanted to the environment of the urban area. The lichen was collected from Mt. Kinabalu Park which is a remote area. Fifteen sampling stations were selected and transplanted lichens were exposed to heavy metals in those … Read more...

Abas A., Asnawi N.H., Aiyub K., Awang A. & Abdullah S.R. (2022): Lichen Biodiversity Index (LBI) for the assessment of air quality in an industrial city in Pahang, Malaysia - Atmosphere, 13(11): 1905 [15 p.]

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...

Abas A., Aiyub K. & Awang A. (2022): Biomonitoring potentially toxic elements (PTEs) using lichen transplant Usnea misaminensis: A case study from Malaysia - Sustainability, 14(12): 7254 [10 p.]

Urban air pollution has been a major concern due to its impact on global public health. Various techniques for monitoring urban air quality have been developed. However, there is currently a dearth of research on how effective bioaccumulators such as lichen are at monitoring urban air pollution. As a result, the purpose of this research is to investigate the use of U. misaminensis as a biological indicator for biomonitoring urban air quality in Malaysia. Three months were spent exposing lichen samples … Read more...

Abas A. (2021): A systematic review on biomonitoring using lichen as the biological indicator: A decade of practices, progress and challenges - Ecological Indicators, 121: 107197 [11 p.]

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...

Abakumov E., Lupachev A. & Andreev M. (2017): Trace element content in soils of the King George and Elephant islands, maritime Antarctica - Chemistry and Ecology, 33(9): 856–868

Trace element concentrations were studied in soils of the King George and Elephant islands in the maritime part of West Antarctica. The lowest concentrations of Cu, Pb, Cd, Zn, Ni and Mn were typical for the pristine soil of Elephant Island. The highest concentrations of these elements were found in the Fildes Peninsula and revealed the influence of human activities in the area of the Bellingshausen station and adjacent waste disposal sites. Ornithogenic soils of the Fildes Peninsula have shown low … Read more...

Ababaikeli G., Abdulla A., Abbas A., Guo S.-Y. & Tumur A. (2018): Diploschistes wui sp. nov., an overlooked saxicolous lichen from Northwestern China - Mycotaxon, 133(1): 141–148

Diploschistes wui is described as a new species, based on three collections from Xinjiang in Northwestern China. It is characterized by a bluish gray and thin thallus, epruinose discs, small, 8-spored asci, and small ascospores. The new lichen resembles D. rampoddensis but is readily distinguished by the absence of surface crystals and pruinose discs. It grows on rocks at elevations above 1800 m. Our ITS rDNA sequence analyses support this species as independent. Key words—biodiversity, central … Read more...
