Abstract. Ice-nucleating particles (INPs) facilitate the heterogeneous freezing of cloud droplets and thus modify cloud properties. Hence, it is important to understand the sources of INPs. During the HyICE-2018 campaign, which took place in the boreal forest of Hyytiälä, substantial concentrations of airborne heat-sensitive biological INPs were observed, despite many potential biological sources of INPs being snow-covered. A potential source of INPs that were not covered in snow was lichens that grow on trees; hence, we investigated these lichens as a potential source of biological INPs in th

Lichens are mutually symbiotic systems consisting of fungal and algal symbionts. While diverse lichen-forming fungal species are known, limited species of algae form lichens. Plasticity in the combination of fungal and algal species with different eco-physiological properties may contribute to the worldwide distribution of lichens, even in extreme habitats. Lichens have been studied systematically for more than 200 years; however, plasticity in fungal–algal/cyanobacterial symbiotic combinations is still unclear.

Lichenicolous fungi colonize lichens to form a variety of biotrophic associations, and while some 300 genera and 1000 species have been recognized, almost nothing is known about their biology. The lichenicolous habit is an unusual one because lichens produce a variety of antibiotic secondary metabolites that are assumed to protect them from parasitic attack. This may explain why lichens are rarely parasitized in nature while nonlichen-forming Ascomycetes are frequently and extensively parasitized.

Many species, mainly those able to produce an oxalate at the thallus-substratum interface, can alter the surface, affecting it chemically. The oxalate remains a noticeable increase even after the lichen has faded, and it makes a major contribution to the structure and composition of the thallus itself. These sever

Lichens, which are fungi that form mutualistic relationships with algae or cyanobacteria, also serve as habitats for a variety of microbial communities. Recently, the diversity of fungi associated with lichens has garnered considerable research attention. However, despite such advances, the mycobiome of lichens and its variations remain inadequately explored in many areas. Over a six-week period in spring, three saxicolous lichen species from the genera Dermatocarpon and Umbilicaria were randomly sampled at two locations in a low mountain range in Bavaria, Germany. The mycobiomes associated wi

Lichens are organism resulting from symbiosis of algae and fungi. These organisms are often used for monitoring of air quality as bio-indicators. This relates to its ability to respond to the presence of pollutants in the air. Sensitive lichens type, will not be found in locations with polluted air conditions. On the other hand, in locations with polluted environmental conditions, the type of lichen commonly found is tolerant lichen.

Abstract:A study of the diversity and distribution of lichens at 10 sites within the Mehao Wildlife Sanctuary in Arunachal Pradesh, India, revealed 177 species, belonging to 71 genera and 35 families. The Sanctuary exhibited almost all the habit and habitat groups of lichens within its climatically heterogenous and altitudinally (400–2700 m) varied landscape. Among the different habitat groups, obligately corticolous lichens were dominant (133 species), followed by facultatively corticolous lichens (occurring on both rock and bark; 25 species), saxicolous lichens (17 species) and terricolous l

Abstract. Forty years ago, lichens were identified as extraordinary biological ice nucleators (INs) that enable ice formation at temperatures close to 0 ∘C. By employing INs, lichens thrive in freezing environments that surpass the physiological limits of other vegetation, thus making them the majority of vegetative biomass in northern ecosystems. Aerosolized lichen INs might further impact cloud glaciation and have the potential to alter atmospheric processes in a warming Arctic. Despite the ecological importance and formidable ice nucleation activities, the abundance, diversity, sources, and

We examined the use and richness of lichens consumed by C. cyphergaster during both the dry and rainy seasons in a semiarid environment in northeastern Brazil by monitoring the foraging of five termite colonies for ten consecutive days during each period. Twenty-nine species of corticolous lichens were consumed by C. cyphergaster, with seasonal variations in the richness of their ingestion.

In this research, sequencing of 16S rRNA was used to investigate the bacterial communities associated with lichens of two growth forms (foliose and crustose). Results showed that Pseudomonadota, Actinomycetota and Acidobacteriota were dominant phyla in both types of lichens, while Acetobacterales and Hyphomicrobiales were the dominant orders.

AbstractLichens respond sensitively to ambient nitrogen levels. Global change, which includes the increase of nitrogen-polluted environments, causes the decline of species sensitive to eutrophication, whereas some species tolerant of high nitrogen levels increase. Lichens produce hundreds of carbon-based secondary substances (so-called lichen substances), most of which are unique to the lichen symbiosis. In the present paper, correlative patterns between the eutrophication tolerance of lichen species and their secondary chemistry are analyzed using two data sets, one classifying the eutrophica

Collembola are terrestrial arthropods that prefer humid environments, probably because their relatively thin chitinous carapace is vulnerable to dehydration. They feed primarily on algae, but certain Collembola may feed on lichens (Leinaas & Somme 1984). They are often found in lichen samples, but the lichens involved do not generally appear to be damaged. Microclimatic conditions within lichens may favour occupation by Collembola as the humidity in the interior of foliose lichen thalli may be relatively high compared to that of the surroundings (Prinzig & Wirtz 1997).

The impact of lichens on the conservation of monuments, such as the World Heritage Site (WHS) of Cappadocian churches, presents a multifaceted challenge for conservators. Previous studies have shown that lichens can both induce deterioration processes of stone through their penetration into the substrate and chemical interactions as well as provide bioprotection, forming encrustations including calcium oxalate layers, which help mitigating the effects of weathering, reducing water penetration and eolian erosion.
