Abstract:

Recently, spectral characteristics of lichens are in focus because of increasing number of spectral data applications in remote sensing of treeless polar and alpine regions. Therefore, species-specific spectral reflectance indices are measured in lichen species dominating polar ecosystems. Hydration status of the lichen thalli, as well as the presence of intrathalline secondary metabolites - which are UV-B absorbing compounds - both affects the spectral reflectance curves as well as numeric values of spectral reflectance indices. In the present paper, the reflectance spectra in 380-800 nm was

Abstract:

This study investigated the species composition, diversity, and relative abundance of crustose and Physcia lichens in the montane forest of Mt. Hamiguitan, located in San Isidro, Mati, and Governor Generoso, Davao Oriental. Two sampling sites were established at approximately 1,200 meters above sea level, where lichen specimens were collected along transect lines using handpicking and scraping methods from various substrates such as tree trunks, rocks, decayed logs, and branches. Specimens were identified based on morphological characteristics, documented, and validated by a lichen specialist.

Abstract:

Lichens were recorded on Quercus petraea trunks and twigs near ammonia recording stations in ‘continental’ Norfolk, and ‘oceanic’ Devon in order to test indicator values developed for epiphytic lichens in areas of high atmospheric ammonia in the Netherlands. Lichens on trunks in Norfolk showed a similar correlation of nitrophyte indices with ammonia concentration and bark pH as those in Holland, whereas in Devon there was no correlation with nitrophyte indices on trunks and a negative correlation with acidophyte indices. Results on twigs in both sites suggest that lichens on twigs respond more

Abstract:

The article highlights the principles of sozological analysis of lichens to form lists of threatened species, determination of their conservation status, and subsequent inclusion into regional Red Data Books. The analysis is useful when we lack information on distribution, quantitative indicators, and population structure of species to be protected. The lichen-adapted sozological matrix includes biological, ecological, biogeographical, sozological and economic characters. To approbate the method, we calculated the sozological index for four lichen species included into the new list of protecte

Abstract:

Extremophile organisms can survive under extreme conditions through tolerance mechanisms. Such organisms include lichens, which are symbiotic associations of fungi and algae and/or cyanobacteria. Among other factors, the high stress tolerance of lichens can be attributed to their ability to synthesize a wide range of metabolites, including chemically diverse lipid compounds. Despite their obvious relevance, the biochemical mechanisms of stress tolerance in lichens that are mediated by changes in the lipid profile remain understudied. Peltigerous lichens constitute a separate division of lichen

AbstractThe epigeic lichen biota of ten post-smelting slag dumps were studied to identify the ecological importance of Cladonia species in spontaneous succession within artificial areas. Species diversity, abundance, constancy and cover indices were determined at the initial stages of vegetation establishment. Substrates under lichen vegetation were characterised in terms of the pH, organic C and total N content, C/N ratio and Zn, Pb, Cd and As concentration. Species occurrence and abundance indices were related to habitat type, enabling the ability to identify species-specific responses to en

Abstract:

Lichens are the dominant autotrophs of polar and subpolar ecosystems commonly encrust the rock outcrops. Spectral mixing of lichens and bare rock can shift diagnostic spectral features of materials of interest thus leading to misinterpretation and false positives if mapping is done based on perfect spectral matching methodologies. Therefore, the ability to distinguish the lichen coverage from rock and decomposing a mixed pixel into a collection of pure reflectance spectra, can improve the applicability of hyperspectral methods for mineral exploration. The objective of this study is to propose

Abstract:

Due to the close linking between the biosphere and atmosphere, there are clear impacts of changes in climate, atmospheric deposition of nutrients/pollutants and land use (Global Changes) on the terrestrial biosphere. Lichens, with a direct dependence on atmospheric conditions, are much more affected by their immediate microclimate than by the ecosystem’s prevailing macroclimate. In contrast to higher plants, poikilohydric organisms have different mechanisms of water and CO2 exchange.

The biotic and abiotic stressors that affect the in-vivo production of these metabolites lead to a constant accumulation of various phytochemicals and their derivatives, which can be helpful in designing and developing potential medications in the future.

Abstract The Teloschistaceae is generally recognized as a rather natural unit in the lichenized Ascomycotina. However, the same family has long been known to include an assemblage of rather unnatural genera and, in addition, there are numerous problems concerning delimitation of species among those genera. Problems related particularly to gradual geographical speciation are discussed in three of the most important genera in the Teloschistaceae and illustrated mainly from the African flora in the genera Xanthoria, Teloschistes, and Caloplaca.

Abstract The Bryopsida, or mosses, are a diverse assemblage of species that form the second largest group of green land plants (Vitt 1982). In general, mosses are poikilohydric and drought tolerant (Proctor 1972; Levitt 1980). As a result of these two characteristics, species can maintain active photosynthesis only when water is available. The ability of this group of plants to tolerate frequent dry periods by coming to thermodynamic equilibrium with their surroundings has enabled them to occupy highly stressed habitats.

However the multiple passes of the fuel pebbles through the core have the disadvantage that the pebble’s movement through the fuelling system and the core produces graphite dust. This dust is transported from the core to other parts of the primary circuit and deposits on components. Although previous experiments performed during AVR operation have given some insight into the dust particle size and activity, there is little information on the behaviour of the dust that was deposited in the system.
