The Lichens in Bario Highlands: Their Natural Occurrence and Secondary Etabolites (original) (raw)

The lichens in Bario highlands: their natural occurrence and secondary metabolites

1998

A total of 36 lichen specimens from 13 genera was collected from the heath forest of Barb Highlands. Thirty-five specimens were identified to species level and one to generic level. Of the species identified, seven represented new records for the island of Borneo. One species, Parmotrema acrotrychum was previously known only from Papua New Guinea and Queensland, Australia and this study had significantly extended its distribution range to the western region. Three Asia-Australia species Parmotrema subcoral linum, Physcidia cylindrophora and Relicina sublanea were also discovered in this study

Additional lichen records from New Zealand 50

2017

Thirteen lichen species from 7 genera have been identified from Bario. The major metabolites present in these species were determined by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). Introduction Bario lies 1200 metres above sea level, on a plateau in the Kelabit Highlands, southeast of Miri in the Fourth Division of Sarawak. It is bordered by the Tamabu Range in the west and the Apo Duet Mountains to the east. It has a mild and cool climate, with temperatures of 18-22°C and an annual rainfall of about 2213 mm. Knowledge of the lichen flora of Malaysia, especially of Sabah and Sarawak, has made great progress during recent years. Din et at. (1997) recently presented a comprehensive account of the lichen flora of Malaysia, summarizing the results of many research efforts undertaken by scientists at several collecting localities in Peninsula Malaysia, Sabah and Sarawak. In May 1995, a scientific expedition was carried out in Bario, Sarawak. The gen...

Rapid assessment of lichen diversity in Baliem Valley, Jayawijaya, Papua, Indonesia

Biodiversitas, 2020

Suharno, Chrystomo LY, Sujarta P, Tanjung RHR. 2020. Rapid assessment of lichen diversity in Baliem Valley, Jayawijaya, Papua, Indonesia. Biodiversitas 21: 2403-2409. Lichen is a form of mutualistic symbiosis between phycobiont and mycobiont. Lichens play an important role in environment, either to maintain the biological diversity and the function of ecosystems. This study is aimed to determine the diversity of species of lichens in the Baliem Valley region, Jayawijaya, Papua. The method used was explorative surveys in several villages in Jayawijaya District. Species identification was based on morphological characteristics. The results showed that there were 37 species of lichen belong to 24 genera and 11 families on several habitats on altitude ranging from 1655 to 2179 m asl with temperatures between 18-26°C. The dominant species were from the families of Parmeliaceae, Cladoniaceae, and Teloschistaceae. The results indicate that the Baliem Valley region rich in lichen diversity ...

Distribution of Lichen Flora at Different Altitudes of Gunung Machincang, Langkawi Islands, Malaysia

Sains Malaysiana, 2011

Lichen samples were collected from Gunung Machincang, Langkawi Islands based on an alternation of altitudes, which are 0, 300 and above 600 m. Morphological identification resulted in 15 genera of microlichens (crustose) and five genera of macrolichens (foliose) and they fall under 14 families. As the altitude increases, the number of foliose type of lichen also increased. The common microlichens obtained were from the Family of Graphidaceae and can be found from the sea level right up to the peak of Gunung Machincang. The most common crustose lichens found were Heterodermia sp., while Eugenia sp. is the most common tree habitat for lichens in Gunung Machincang, Langkawi Islands. This study represents the first record of lichens in Gunung Machincang, Langkawi Islands, Malaysia.

A New Species and New Records from the Tasmanian Lichen Flora

Muelleria: An Australian Journal of Botany

Tasmanian lichen flora. Muelleria 7(4): 507-517 (1992).-A new lichen from Tasmania and South Australia, Neofuscelia subloxodeUa Elix & Kantvilas, is described. Twenty-three additional lichen taxa are reported from Tasmania for the first time, and notes on their distinguishing features, distribution and ecology are provided. The new combination, Parmelina pseudorelicina (Jatta) Kantvilas & Elix, is proposed.

New taxa and new records from the Tasmanian lichen flora

Papers and Proceedings of the Royal Society of Tasmania, 1995

Three new lichens from Tasmania, Cladonia sulcata var. de p leta Elix & Kancvilas, Parmelia tarkinemis Elix & Kancvilas and Xanthoparmelia jarmaniae Elix & Kancvilas arc described. Eleven additional taxa are reported from Tasmania for the fi rst time, and notes on their distinguishing features, distribution and ecology are provided.

Lichens Diversity of Kabawetan District Kepahyang, Regency Bengkulu Province

2021

Organisms formed as a mutualism symbiotic between fungi as mycobiont and algae as photobiont, Lichens, recently has been world-wide explored due to its uniq characteristcs and its highly beneficial especially in using this creatures as herbal medicine, environmental bioindicator. About 100.000 Lichens species grown around the world. However, in Indonesia Lichens has not well known as well as well explored yet, it has not been known by most people even though it's grown all over the region. In Kabawetan District, Kepahyang Region; one of a highland region of Bengkulu Province, Lichens can be found everywhere; they have grown as an epiphyte at various substrates; trees barks, stones, fences, etc. The purpose of this research was to study the diversity of lichens and their substrates at Kabawetan District Kepahyang Regency Bengkulu Province. Lichens investigation has been conducted on May – November 2019. Samples were collected from the villages of Kabawetan District. Samples then ...
