To get insights into the effect of phylogenetic distance on the priority effect of species arriving in different order, we conducted a multispecies greenhouse experiment.
We created 10 species “triplets” representing a gradient of phylogenetic distance between early-arriving species (early species) and late-arriving species (late species) from 5 to 270 Myr of evolutionary history. Each triplet consisted of a native late species, a native early species, and an exotic early species, allowing us to create one sympatric and one allopatric early-late species pair per triplet. Each species appears only in one single triplet, resulting in 30 species in total. All sympatric and allopatric species pairs grew with four replicates, each in different greenhouse cabins.
Early species were sown in 10l boxes and cut after two (first harvest) and four (second harvest) months. After the second harvest, late species were sown into the early species populations as well as into empty control boxes (100 seeds/box). Every week, emerging and dying seedlings were counted and reduced to six seedlings per box. Three months after sowing the late species, all late species individuals were counted, and dry aboveground biomass of the adult plants was harvested (final harvest).
The data are provided in the file “Priority effects and phylogenetic distance.csv”. All the metadata, including the variable names, a short description, the type and unit as well as some additional information are provided in the file “Metadata.csv”. Unless otherwise specified in “Metadata.csv”, NA was used to indicate data that could not be measured.
All csv files are encoded as UTF-8. |
