Lichens are known to be more sensitive indicators of ecosystem functioning and disturbances than any other cryptogams and vascular plant communities. Himalayan habitats, despite their stressed climates, harbor some of the unique biodiversity of the region, vital for overall ecosystem functioning and stability. Lichens, due to their desiccation tolerance, are able to survive in high altitude hab...

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 ...

This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...

This paper presents a system for modeling lichens and simulating their propagation and growth in a virtual scene. Lichens colonize almost every substrate in nature and play an important role in the visual appearance of a natural object. The propagation of lichens over the substrate is performed by an Open Diffusion Limited Aggregation model constrained by the characteristics of the environment....

What are lichens? The term lichen refers to a symbiotic association between a filamentous fungus, the ‘mycobiont’, and at least one photosynthetic organism, the ‘photobiont’, consisting of a micro alga, a cyanobacterium, or both (Figure 1). Although the symbiotic nature of lichens was first revealed in 1867, the development of a lichen thallus is often so integrated (Figure 1D) that they have b...

Lichens are used as effective monitors to detect low-level air pollution which may affect different flora and fauna communities. Epiphytic lichens have been widely recognized as effective eco-friendly bio-monitors for detection of metal deposition on trees, rocks and bare ground. This article is concerned with the use of lichens in bio-monitoring of air pollution, how the lichens do recognize a...

Antioxidant activity of symbiotic organisms known as lichens is an intriguing field of research because of its strong contribution to their ability to withstand extremes of physical and biological stress (e.g. desiccation, temperature, UV radiation and microbial infection). We present a comparative study on the antioxidant activities of 76 Icelandic and 41 Hawaiian lichen samples assessed emplo...
