Abstract1. Species distribution models (SDMs) are used for understanding where species live or could potentially live and are a key resource for ecological research and conservation decision-making. However, current SDM methods often perform poorly for rare or inadequately sampled species, which includes most species on earth as well as most of those of the greatest conservation concern. 2.

This paper reports on data from field experiments on fire history and climate impacts on high-elevation Puna grasslands in the eastern Peruvian Andes conducted between 2018 and 2020. It contains data on plant community, vegetation structure, plant functional traits, biomass, ecosystem fluxes, and climate data collected in one or several campaigns between March 2018 and March 2020.

AbstractTrees are pivotal to global biodiversity and nature’s contributions to people, yet accelerating global changes threaten global tree diversity, making accurate species extinction risk assessments necessary. To identify species that require expert-based re-evaluation, we assess exposure to change in six anthropogenic threats over the last two decades for 32,090 tree species. We estimated that over half (54.2%) of the assessed species have been exposed to increasing threats.

Deviations of phylogenetic and functional beta-diversity and associated factorsNull model analyses showed that deviations of the observed phylogenetic and functional turnover and nestedness from random expectations based on observed taxonomic beta-diversity and site-specific regional species pools were not evenly distributed across space (Fig. 4).
