The paper introduces FennoTraits, a dataset of plant functional traits and community composition from northern European flora, highlighting trait patterns and species distribution across seven study areas.

The paper introduces Hubbell regression to estimate biodiversity descriptors and finds actual evapotranspiration is the largest predictor of arthropod diversity, with human activity reducing insect richness in tropical and dry zones.

NordicTraits provides a comprehensive, imputed functional trait dataset for vascular plants in Nordic countries, enabling ecological research on plant strategies and environmental responses.

This paper presents a high-resolution microclimate dataset for a sub-Arctic biodiversity hotspot in Finland, generated using Random Forest models from 430 measurement locations.
