Abstract

An enumeration of 105 species of lichens belonging to 48 genera and 21 families recorded in and around Nainital city in the Uttarakhand is provided. The localities around the city centre exhibit scarce growth of lichens as compared to the localities situated in the outskirts. The Snow View and Kilbury localities situated in the outskirts of the city have maximum diversity of lichens represented by 34 and 28 species respectively. The Ayarpatta and D.S.B. campus area in the centre of the city have 19 and 9 species respectively. Among the different trees Quercus supports the maximum growth of lichens. Lichen genera Heterodermia with eight species and Caloplaca and Lecanora with seven species each showed their dominance in the area. Lichen families Parmellaceae with eleven genera Physclaceae with eight genera are the dominant families in the area.

Abstract

The paper enumerates 50 species of lichens belonging to 25 genera and 14 families from Satna and Panna districts in Vindhyanchal Range of Madhya Pradesh. The Satna district is represented by the occurrence of 40 species of lichens belonging to 23 genera under 13 families. The districts showed occurrence of 21 corticolous and 18 saxicolous species, with dominance of crustose lichens represented by 25 species followed by 8 species of squamulose and 7 of foliose lichens. The Panna district showed occurrence of 37 species belonging to 21 genera under 12 families. Both saxicolous and corticolous lichens are represented by 18 species each while a single species is found both on rocks and bark of trees. The crustose lichens dominates the district with 21 species, followed by 8, 6 and 2 species of foliose, squamulose and leprose form respectively. The Mangifera indica trees in dense, moist shady mango orchard exhibit luxuriant growth of lichens under Physciaceae family. Among the saxicolous genera, the crustose and squamulose growth form of the member of lichen families Teloschistaceae and Peltulaceae exhibit their luxuriant growth in the area.

Abstract

Achanakmar Tiger Reserve in Chhattisgarh state is one of the highly potential conservational areas having rich floral and faunal diversity. The present study reveals the occurrence of epiphytic lichen flora of the Tiger Reserve. Arthorniaceae, Chrysothricaceae, Graphidaceae, Lecanoraceae, Parmeliaceae, Pertusaricaeae, Physiciaceae and Ramaliaceae are the most common among different lichen families while Caloplaca, Cryptothecia, Dirinaria, Heterodermia, Lecanora, Lepraria, Parmaotrema and Pertusaria are the dominant lichen genera on trees. The crust forming together with leprose to sub-leprose lichens represents primary colonization of lichens in tropical dry and moist deciduous forests of the region comprising of young tree vegetation. The present study provides valuable information of lichen succession with respect to microclimatic condition.

Abstract

The presence of carotenoids in 10 species of the lichens form India was studied. The investigations revealed the presence of the following carotenoids ; α - carotene, β -carotene, β -cryptoxanthin, lutein, zeaxanthin, β -carotene epoxide, lutein epoxide, antheraxanthin, violaxanthin, neoxanthin, canthaxanthin, astaxanthin, mutatoxanthin, flavochrome, capsochrome and β -apo-10'-carotenal.

The total carotenoid content of the material ranged from 15.0 to 31.6 μg g^-1 dry weight.'

Abstract

An enumeration of the diversity and distribution of lichens in Milam Glacier valley of Pithoragarh district in Uttarakhand is provided. The area shows an occurrence of 232 species of lichens belonging to 36 families and 73 genera. Parmehaceae with 18 genera and 49 species and Physciaceae with 7 genera and 26 species dominate the area. Among different growth forms of lichens, foliose comprises the highest number of 104 species, followed by 87 crustose lichens. The valley exhibits maximum number of bark and rock inhabiting lichens represented by 132 and 123 species respectively.

Abstract

The present study was conducted for documenting the epiphytic lichen diversity in PirPanjal mountain ranges of Inner Himalaya of Jammu and Kashmir State of India. A total of 21 species of epiphytic lichens growing over numerous tree species were collected, identified and documented from the study area. It was further observed that Quercusleuco trichophora appeared to be the most favoured tree species for the epiphytic lichens as nine out of the 21 species were found to be growing on it. Many factors during the course of present study have been identified which have badly impacted the growth of epiphytic lichens in the region. Many of the tree species which form an ideal habitat for these lichens are being exploited for one or the other reason. The loss of tree species, therefore, will lead to the vanishing of many important lichen species from the area. It will ultimately lead to loss of biodiversity in general and epiphytic lichens in particular.
