Background and aims Although fine roots play a key role in belowground carbon and nutrient cycling, our understanding of species-specific differences in their phenology, morphology, and turnover remains limited – especially across contrasting tree functional types such as evergreen conifers and deciduous broadleaved species. Improved insight into fine root dynamics is essential for understanding how different forest types shap...

Single‐cell sequencing (SCS) technology has revolutionized the study of cellular heterogeneity by enabling the exploration of biological processes at high resolution. While traditionally applied to mammalian models, recent advancements have extended SCS to ecologically and evolutionarily crucial lower vertebrates (particularly fish) and diverse invertebrates (including Urochordata, Echinodermata, Arthropoda, Mollusca, and Coel...
