The Desert in Bottles: The Culturable Microbiome of the Atacama Desert's Grit Crust

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
The grit crust represents a unique biocrust type of the coastal Atacama Desert. Cyanobacteria, green algae and free‐living fungi were isolated along a fog gradient. Phylogenetic relationships indicated novel taxa and framed an indigenous microbiome. Microclimate and soil data support functional groups related to sites.

A thinner jacket for frosty and windy climates? Global patterns in leaf cuticle thickness and its environmental associations

open access: yesNew Phytologist, Volume 248, Issue 1, Page 107-124, October 2025.
Summary Plant cuticles protect the interior tissues from ambient hazards, including desiccation, UV light, physical wear, herbivores and pathogens. Consequently, cuticle properties are shaped by evolutionary selection. We compiled a global dataset of leaf cuticle thickness (CT) and accompanying leaf traits for 1212 species, mostly angiosperms, from 293
