Abstract. Subbaiyan R, Ganesan A, Dhanuskodi S. 2023. Ecolichenology of Eastern Ghats diversity against climatic fluctuations in Kolli Hills, India. Biodiversitas 24: 625-635. Lichens are major components earthbound and marine environments. A lichen is a symbiotic form algae fungi adapted to survive different altitudes environmental conditions. The morphology divided into three, based on their ...

lichens are composite organisms formed by a fungus and a green alga and / or a blue-green bacterium. they are recognized as being very sensitive to atmospheric pollution and respond to factors that influence human and environmental healths. since 1860, lichen has been identified as a biological indicator to detect air pollution in great britain and europe. lichens have the high sensitivityto ni...

The paper describes two new records of micro-lichens from South Korea. Detailed taxonomic descriptions and comments are presented for both of the studied taxa. The lichen genus Thelotrema is reported for the first time in Korea.

Mushrooms are macrofungi that famous for their nutritional and pharmaceutical values. On the other hand, lichens form of symbiosis representing complex relation between fungi algae. Understanding ability to grow over anything, this review is focusing on endophytic capable growing in association with mushrooms lichens, respectively. Although reports describing these rare, it important highlight ...

There are marked declines in precipitation, mean temperatures and the number of lichen species with increasing latitude in Antarctica. However, it is not known which factors are the predominant controllers of biodiversity changes. Results are presented from over two years of almost continuous monitoring of both microclimate and activity in lichens at Livingston Island, South Shetland Islands, 6...

The increasing demand for forest-derived bio-fuel may decrease the amount of dead wood and hence also the amount of available substrate for saproxylic ( = dead-wood dependent) organisms. Cut stumps constitute a large portion of dead wood in managed boreal forests. The lichen flora of such stumps has received little interest. Therefore, we investigated which lichens that occur on stumps in young...

Chronic diseases such as cancer, diabetes, neurodegenerative and cardiovascular diseases are characterized by an enhanced state of oxidative stress, which may result from the overproduction of reactive species and/or a decrease in antioxidant defenses. The search for new chemical entities with antioxidant profile is still thus an emerging field on ongoing interest. Due to the lack of reviews co...

Air pollution and climate change are threats to maintaining ecological health of protected areas. Protected Area managers require a meaningful way to measure impacts of these threats. Lichens provide a relevant, sensitive and measurable indicator for long-term monitoring. Hundreds of studies have linked lichen communities to air quality, and several long-term lichen monitoring programs in Europ...

Extremes in δ15N values in mangrove tissues and lichens (range =+4 to −22‰) were measured from a mangrove forest ecosystem located on Twin Cays, offshore islands in Belize, Central America. The N isotopic compositions and concentrations of NH+4 /NH3 in porewater, rainwater, and atmospheric ammonia, and the δ15N of lichens, mangrove leaves, roots, stems, and wood were examined to study the bioge...

Although lichens (lichen-forming fungi) play an important role in the ecological integrity of many vulnerable landscapes, only a minority of lichen-forming fungi have been barcoded out of the currently accepted ∼18 000 species. Regular Sanger sequencing can be problematic when analyzing lichens since saprophytic, endophytic, and parasitic fungi live intimately admixed, resulting in low-quality ...
