Symbiotic Versatility in Action: Trebouxia Diversity Expands the Niche of the Lichen Xanthoria parietina.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Xanthoria parietina is one of the most widespread and ecologically versatile lichens, yet the diversity of its fungal and algal symbionts and their contribution to its broad ecological niche remain poorly understood. Genetic diversity and phylogenies of both lichen symbionts were inferred from nrITS data. Mycobiont-phycobiont interaction networks were constructed, and ecological niches of associated Trebouxia species were modelled using 19 bioclimatic variables. Phylogenetic analyses revealed high diversity within Xanthoria parietina and clarified the placement of poorly studied species within the genus Xanthoria (e.g., X. monofoliosa and X. aureola s. lat.), and revealed a novel lineage (Xanthoria sp. 'hydra'). All the photobionts belonged to Trebouxia clade A; comprising nine Trebouxia species-level lineages, including the newineage Trebouxia sp. A56. Trebouxia decolorans (A33) was the most frequent photobiont and exhibited the broadest climatic niche, whereas T. solaris (A35) and T. tabarcae (A48) occupied narrower iches. Species-distribution models predicted widespread suitability for T. decolorans across Europe and coastal-Mediterranean suitability for T. tabarcae. Xanthoria parietina displays remarkable symbiont flexibility in associating with multiple Trebouxia lineages within clade A. This flexibility likely broadens its ecological niche and enhances its ability to thrive across heterogeneous Mediterranean environments.
