Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

2025-11-18
Taxon • Level 2 (6 panels)
S. Ekman, Måns Svensson, Martin Westberg

This study employs molecular phylogenetics, species delimitation, and machine learning to examine species boundaries within the lichen genus Arctomia. Key findings reveal the monophyly of Arctomia and identify three distinct species within A. delicatula: A. delicatula s.str., A. acutior, and A. confusa. Machine learning accurately classified species using morphological data despite subtle differences.

Plant–soil feedback (PSF) dynamics, crucial for plant community composition, are influenced by nutrient factors, especially nitrogen (N) and phosphorus (P) levels and ratios. This study explored PSF across six plant species, revealing that nutrient supply and N:P stoichiometry significantly affect PSF, independent of species' natural niches. Such insights are vital for understanding nutrient-driven impacts on ecological balance and human-altered nutrient cycles.

Eisosomes are subcellular structures associated with membrane organization and stability, pertinent to fungal pathogens like Candida albicans. Recent research highlights the protein Ker1's role in this yeast, revealing its necessity for hyphal growth, invasive growth in agar, and resistance to copper and cell wall perturbations, underscoring its potential as a target for antifungal strategies.

This study explores the genetic relationships of Aspergillus fumigatus in hospital settings during the COVID-19 pandemic. It identifies genetic links between clinical and environmental isolates, suggesting potential nosocomial transmission, especially in ICUs. Findings raise concerns over current isolation practices and underscore the need for stringent environmental controls to mitigate CAPA risk.
