Abstract Lichens are one of the most responsive components ecosystem to reactive forms nitrogen. In this work, we selected lichen genera Cladonia and Usnea , composed terricolous epiphytic lichens respectively, described as sensitive nitrogen, test effects different doses nitrogen on physiological parameters (photobiont mycobiont vitality, chitin quantification, content stable isotopes analysis...

The chemical structures of the glucans, galactoglucomannans and galactomannoglucans of two species of the Cladonia, section Cocciferae, Cladonia miniata and Cladonia salmonea, were determined and compared. alpha-D-Glucans of the nigeran type were isolated from both species, in common with all Cladonia spp., along with galactoglucomannans containing (1-->6)-linked main-chains of alpha-D-Manp uni...

In traditional medicine, Cladonia lichens are used for several disorders like hypertension, headaches, dizziness, cough, and menstrual disorders. The study aimed to determine the biological activities of 70% methanol extracts nine species from Turkey. chemical composition was analyzed via spectrophotometric chromatographic (HPLC) techniques. DPPH● (1,1-diphenyl-2-picrylhydrazyl) ABTS+● (2,2'-az...

Lichens are obligate symbioses between fungi and green algae or cyanobacteria. Most lichens resynthesize their symbiotic thalli from propagules, but some develop within the structures of already existing lichen symbioses. Diploschistes muscorum starts as a parasite infecting the lichen Cladonia symphycarpa and gradually develops an independent Diploschistes lichen thallus. Here we studied how t...

Abstract • We assess the recovery of microbial networks underneath crust to repeated rainfall. The network fragmentation after second heavy rain was milder than at first one. Cohesive were related high enzyme activity involved in C, N, and P cycles. Loose Ca, K, Mg, NH 4 organic N. dry-crusted soils collapsed rain. Biological soil crusts (BSCs) are an important multi-trophic component arid ecos...

The antioxidative, antimicrobial and antiproliferative potentials of the methanol extracts of the lichen species Parmelia sulcata, Flavoparmelia caperata, Evernia prunastri, Hypogymnia physodes and Cladonia foliacea were evaluated. The total phenolic content of the tested extracts varied from 78.12 to 141.59 mg of gallic acid equivalent (GA)/g of extract and the total flavonoid content from 20....

Green roofs are constructed ecosystems that provide ecosystem services in urban environments. Shallow substrate green roofs subject the vegetation layer to desiccation and other environmental extremes, so researchers have evaluated a variety of stress-tolerant vegetation types for green roof applications. Lichens can be found in most terrestrial habitats.  They are able to survive extremely har...

A total of twenty four lichen species belonging to six families were collected from mountainous region of Nepal. The methanol extracts of each species were tested for antimicrobial and antioxidant activities in vitro. It was found that extracts of twenty one lichen species were active against B. subtilis and seven species were active against S. aureus. Similarly, in DPPH assay, three species Pe...
