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...

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...

Abas A. (2021): Monitoring physiological and chemical response of lichen in free air CO2 enrichment (FACE) station, IOP Conference Series: Earth and Environmental Science, 842: 012031

The elevation of CO2 will bring forth several effects on the plant's growth especially the physiological traits and chemical responses. However, there is lacking knowledge on how the elevation on CO2 will affect lichen physiology and chemical response. Therefore, this study aims to study the physiological changes in lichen in FACE Station and to analyze the chemical profile changes of lichen in FACE Station. This study has been conducted in FACE Station at Jengka, Pahang. A total of 20 sampling trees … 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...

Abas A. & Din L. (2021): Diversity, composition and distribution of lichens along elevational gradients in the tropical mountain forest of Gunung Nuang, Selangor, Malaysia, eco.mont, 13(1): 4-11

This study aims to explore how lichen diversity, composition and distribution vary with altitude, and environmental factors (temperature and relative humidity). The study was conducted in the forest of Gunung Nuang, Selangor at five sites (at different altitudes) which were chosen as sampling stations. Forty-four lichen species were identified. Their diversity, composition and distribution correlated significantly with the forest’s altitude and environmental factors, increasing at higher altitudes. … Read more...

Abas A. & Din L. (2021): The diversity of lichens along elevational gradients in the tropical montane Forest of Selangor, Malaysia, Sains Malaysiana, 50(5): 1199-1209

This study aims to explore how lichen diversity, composition, and distribution vary with altitude, and environmental factors (temperature and relative humidity). The study was conducted in the forest of Gunung Bunga Buah, Selangor at five sites (different altitudes). Forty-four lichen species were identified. Their diversity, composition, and distribution correlated significantly with the altitude and environmental factors, increasing diversity at higher altitudes. Graphidaceae and Physciaceae species … 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., 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., 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...
