Data and code from: The overlooked link between different resource partitioning strategies and plant species richness in tropical alpine ecosystems

Species co-existence is based on resource partitioning and modulates biodiversity patterns across climates, latitudes, and altitudes. Resource partitioning can occur via niche size or separation in the geographic range or ecological niche. While resource partitioning promotes biodiversity, the impact of different partitioning strategies on species richness remains largely unexplored. Study locations: two ecosystems with similar climates and ages, the species-rich tropical alpine ecosystem in the South American Andes and the more species-poor tropical alpine ecosystem in the eastern African mountains. Study time period: present-day distribution and climatic conditions, integrating phylogenetic information extending back to the last 7 million years maximum. Major taxa studied: Six lineages from the Asterales; three in each ecosystem, respectively. We test whether geographic range and climatic niche partitioning strategies may explain differences in species richness between the two ecosyst..., , , # Data and code from: The overlooked link between different resource partitioning strategies and plant species richness in tropical alpine ecosystems

#### Data

We studied six Asterales lineages in the tropical alpine ecosystems of South America and East Africa, i.e., Loricaria, Senecio, and Oritrophium in South America and Dendrosenecio, Helichrysum, and Lobelia in East Africa. We compiled occurrence information from herbaria and supplemented it with GBIF data ([https://doi.org/10.15468/dd.8cpqns](https://doi.org/10.15468/dd.8cpqns)). The table contains all columns as provided by GBIF (simple format; [https://techdocs.gbif.org/en/data-use/download-formats#simple](https://techdocs.gbif.org/en/data-use/download-formats#simple)), for the occurrence data from herbaria, some column information was not available and is coded as NA (not available).

Phylogenetic data for each lineage are based on Compositae1061 loci (Mandel et al., 2014); newly sequenced material is available under Bioprojec...,
