Elevation and land use/ land cover (LULC) plays an important role in the diversity of lichens in the Himalayas. The elevation gradients and LULC can be remotely assessed using remote sensing (RS) and geographical information systems (GIS). The current study was done in the Chopta-Tungnath landscape in the Kedarnath wildlife sanctuary, western Himal...

The lichens along with their natural substratum colonize a variety of man-made substratum. After about half a century of lichenological research in India, there has been no record of lichen colonization on the man-made artificial substratum. The authors here for the first time report colonization of five species of lichens on three samples from two...

Lichen survey in Jammu and Kashmir State was initiated during the early 1930s, but detailed explorations started in 1949. The present chapter reports occurrence of 424 species of lichens in the State, belonging to 126 genera in 38 families; these represent ˃ 18% of total lichen species reported so far from India. Parmeliaceae is the largest family...

Blue-green algae containing cyanolichens are a mutualistic association of a dominant fungus and blue-green algae, either as primary photobiont (bipartite cyanolichen) or as secondary cephalodiate photobiont along with a green alga (tripartite cyanolichen). Cyanolichens as a photobiont functional group are known as one of the most sensitive lichen g...

The high altitude Himalayan habitats are distinguished by highly stressful environmental conditions for organisms. Lichens are fungal and algal/ cyanobacterial symbioses resulting in the production of specific metabolites and are among the dominating organisms in the higher elevations of Himalaya. Through their morphological and chemical adaptation...

The antioxidative, cardioprotective, and anticancer potential of extracts of the edible lichens Everniastrum cirrhatum and Parmotrema reticulatum were evaluated. Acetone extracts of P. reticulatum exhibited nitric oxide scavenging and anti-lipid peroxidation in the range of 35.0–97.0%. IC50 values of extracts for angiotensin-converting enzyme and H...

The use of bioindicator communities (lichen) to assess the environmental status of an area is a well-proved strategy to monitor any habitat without any logistic and instrumental facilities. In the present study, 13 bioindicator communities of lichen have been used to assess the environmental status of holy pilgrimage (Badrinath), western Himalaya,...

Twenty-eight new records of lichenized fungi have been reported from the community forest of Dadeldhura situated in Mahakali zone of far west Nepal. The species diversity is distributed in 13 families (Acarosporaceae, Arthoniaceae, Caliciaceae, Chrysothrichaceae, Cladoniaceae, Collemataceae, Graphidaceae, Lecanoraceae, Parmeliaceae, Physciaceae, Py...

Context: Lichens are source of natural bioactive compounds which are traditionally used to cure a variety of ailments. Objective: The objective of this study is to assess free radical scavenging, prolyl endopeptidase inhibitory (PEPI), and antimicrobial potential of a high altitude lichen species Cetrelia olivetorum (Nyl.) W. L. Culb. & C. F. Cu...

Elevation confers limitations on distribution of organisms through correlated variations in temperature, moisture, radiations and precipitation. The elevation gradients of terricolous lichen species richness in Garhwal, western Himalaya were assessed using generalized additive models, in order to compare distribution patterns of different growth-fo...
Conference Paper
Full-text available
The study recorded three terricolous lichen species belonging to three genera and five families. Fruticose lichen Stereocaulon foliolosum was dominant species, present in 3 of the four sampling sites; covering an altitudinal range of 3026- 3789 m followed by two foliose species Umbilicaria indica and Cetrelia pseudolivetorum, present only at lower...

Elevation linked climatic factors such as temperature, moisture, radiation and precipitation delimit the distribution of organisms. Effect of elevation was studied on lichen diversity in seven spatially separated sites of Zanskar valley, in Ladakh region of Indian Himalayan state of Jammu and Kashmir. The study revealed presence of 24 species, of l...

Morphological growth forms confer ecological adaptability to lichens species and are indicators of habitat conditions and various climatic as well as zooanthropogenic pressures. Lichens samples from six sites in two locations of Badrinath valley were studied in order to assess the influence of macro-scale environmental variables (i.e. altitude, rel...

The study aims to understand the effect of usnic acid and standardized extract of Cladonia furcata on gastroesophageal reflux disease (GERD) in rats. The hydro-ethanolic extract of C. furcata in doses of 50, 100 and 200 mg/kg were administered orally twice daily at 10:00 and 16:00 h, respectively, for 5 days and usnic acid (100 mg/kg) and omeprazol...

Indian lichenological studies have elucidated terricolous lichen genera in various enumerations and taxonomic records but have never taken them as a functional group. Poor understanding of terricolous lichens in India can be attributed to absence of proper curation of specimens, less understood habitat distribution of terricolous lichens and extrem...

Lichens the symbiotic association of a fungi and algae are dominant vegetation in the temperate-alpine habitats of Himalayas. Among the various lichen functional groups, the lichen habitat subset-soil inhabiting terricolous lichens are the dominant lichens beyond tree lines in alpine habitats of Himalaya. The Himalayan terrestrial alpine habitats a...

Lichens, a mutualistic association of fungi and algae (green and/ or blue green) are among the most sensitive indicators of habitat heterogeneity in Himalayas as lichen growth forms are very responsive to change in substratum level micro-scale variables and macroscale environmental variables. Eastern Himalayas in India has a more complex geographic...

The symbiotic association of fungi and algae/cyanobacteria, known as lichen, is one of the most successful associations in nature. Dominated by ascomycetous mycobiont majority (85 %) of lichens have green algae as their photobionts, rest (15 %) have cyanobacteria as their primary or secondary photobionts. Cyanolichens, owing to their ability to fix...
