Ultramafic specialist lichens persist through flexible symbioses structured by climate-driven filtering and modulated by substrate effects

Miroslav Caboň, Marek Slovák, Marek Svitok, Jana Steinová et autres

Ultramafic substrates impose severe edaphic stress characterised by metal toxicity, nutrient imbalance, and extreme microclimatic conditions, creating spatially fragmented habitats that can shape evolutionary and ecological dynamics of associated organisms. Together with climatic variation, such factors may also influence the structure of …

Unravelling the Secret of Phantom Phenotypes in Macrolichens: Insights From Cladonia bellidiflora Complex

Eliška Konečná, Jana Steinová, Ivana Černajová, Felix Grewe

Lichens are unique among symbiotic organisms because their distinctive features develop only through interactions between the partners and differ from the appearance of each partner when grown separately in culture. Traditionally, lichen phenotype has been assumed to be determined by the mycobiont; …

Oribatid mites like lichens—feeding preferences among three Cladonia species with different chemistry

Věra Vtípilová, Tobias Pfingstl, Heda Ghlimová, Jan Mourek et autres

Lichens in general and members of the genus Cladonia in particular are known for their repertoire of chemical substances. These substances have been attributed various roles, including a role in the defence against herbivores. Unsurprisingly, Cladonia species share habitats with many small …

Dismantling of the Mock-Up Josef in situ experiment after 10 years of operation – a comprehensive analysis of the bentonite barrier

Radek Vašíček, Šárka Šachlová, Jana Steinová, Kateřina Černá et autres

Abstract The Josef Mock-Up experiment, conducted in the Josef Underground Laboratory, simulated the vertical disposal of a spent nuclear fuel container surrounded by compacted, artificially Na₂CO₃-activated Czech bentonite (“Bentonite 75”) under repository-relevant conditions. This approx. 50% scale model (height 2.2 m, diameter …

Oribatid mite fauna of three members of the lichen genus Cladonia in Europe – observations on species richness, endophagous juveniles and their morphology

Tobias Pfingstl, Věra Vtípilová, Heda Ghlimová, Jan Mourek et autres

Lichen - mite interactions have generally been acknowledged for a long time and yet, despite their ubiquity they are rarely studied in detail. Oribatid mites occur on and in various lichens and prior research has shown that mites use them as shelter …

Cladonia rubrotincta , a new species distinct from C. norvegica

Věra Vtípilová, Einar Timdal, Eva Stodůlková, Jaroslav Semerád et autres

Abstract Cladonia norvegica was originally described from Norway based on different morphological and chemical characters distinguishing the species from C. coniocraea. Shortly after its description, material containing red spots on the thallus was reported from different parts of the world, but the …

The curious case of Cladonia luteoalba: no support for its distinction

Ivana Černajová, Jana Steinová, Zuzana Škvorová, Pavel Škaloud

Abstract Cladonia luteoalba shows a specific pattern in chemical variability. Its chemotype coincides with that of the associated Cladonia thalli. This has led to the formation of various hypotheses, but its true nature has never been clarified. We collected C. luteoalba in …
