TL;DR: This study reveals that the photobiont, generally the subsidiary member of the symbiotic lichen association, could exhibit clear preferences for environmental factors that may limit the ecological niches available to lichens and lead to the existence of specific lichen guilds.

TL;DR: A molecular investigation of 41 cultured strains, for which nuclear-encoded ITS rDNA and partial actin I sequences were determined, revealed considerable differences in their evolutionary dynamics as well as sequence variation in Asterochloris.

TL;DR: This study illustrates that successful lithobiontic microbial colonization at the limit for microbial life is the result of a combination of adaptive strategies to avoid excess solar irradiance and extreme evapotranspiration rates, taking advantage of the complex structural and mineralogical characteristics of gypsum deposits—conceptually called “rock's habitable architecture.”

TL;DR: It is suggested that lichen surfaces represent a potential temporary niche for free-living stages of lichen photobionts, which could facilitate the establishment of further lichens in the proximal area.

TL;DR: Cytological, reproductive and morphological variation, investigated by means of landmark-based geometric morphometrics, were in congruence with molecular data, and confirmed the existence of genetically distinct lineages within N. cryptocephala, and revealed a close relationship between N. trivialis and N. cryptotenella.
