File/Folder Details
==========================

Folder: Tree_files
-------------------

Phylogenies inferred from 79 coding DNA sequences (CDS) and four noncoding rRNA genes. Tip labels contain taxon names (as identified by accession provider), NCBI number, project ID number and sequencing ID number.

* 230525_rooted_seedtree_families.tre
-> Phyloalps tree that has been rooted on Ginkgo biloba, and has been subset to include only seed plants and exclude duplicated accessions.

* 230525_rooted_seedtree_branch_x20.tre
-> As above, but branch lengths multiplied by 20 to improve dating outcomes. This is the input phylogeny to the TreePL analysis.

* 230601_treePLV2_final_run1_01.tre
-> Fully dated seed plant tree. This is the output phylogeny from the TreePL analysis.

* 231108_pruned_phyloalps_tree.tre
-> Dated tree used for downstream analyses. This is "230601_treePLV2_final_run1_01.tre" filtered to include only angiosperms and a single accessions per species.

* Bootstraps.zip
-> Zip file containing 100 dated bootstrap phylogenies containing the same accessions as "230601_treePLV2_final_run1_01.tre".

Folder: TreePL
-------------------

* 230525_treepl_opt_V2_final_run1_01.txt
-> The TreePL optimisation file required to date the phylogeny

Folder: Biogeographic_origins
-------------------

Results of a literature search to find the biogeographic origins of all EASI species

* 231206_biogeographic_origins.csv
-> Variables: Tip = Accession name in the phylogeny
Taxon name = Name of the taxon (taxonomy following Euro+Med PlantBase (http://www.europlusmed.org))
Assembly_process = The assembly process generating each sky-island species.
Reference = Reference used to assign biogeographic origin
Biogeographic_origin = The biogeographic origin as found in reference
Broad_biogeo_category = Biogeographic assignation in this manuscript

Folder: Data
-------------------
All data needed to reconstruct assembly processes through time

* 240221_species_classified_by_process.csv
-> This file contains the ancestral and current elevational and geographic distributions of all species in this study.
-> Variables: Tip = Accession name in the phylogeny
EuroMedAcceptedName_formatted = Name of the taxon (taxonomy following Euro+Med PlantBase (http://www.europlusmed.org))
naming_family = Taxon family
Distribution = Distribution across the European Alpine System. EAS = core distribution of the taxon lies within the European Alpine System. Non_EAS = core distribution of the taxon does not lie within the European Alpine System.
Status = Whether we considered the taxon to be a sky-island or non-sky-island taxon. Island = sky-island taxon. Mainland = non-sky-island taxon.
Ancestor_EN = Ancestral distribution across the European Alpine System based on an ancestral state reconstruction. EAS = core distribution of the taxon lies within the European Alpine System. Non_EAS = core distribution of the taxon does not lie within the European Alpine System.
Ancestor_IM = Whether that ancestral state of the is sky-island or non-sky-island based on a ancestral state reconstruction. Island = sky-island taxon. Mainland = non-sky-island taxon.
Clade_name = Identifier to show which species are part of the same sky-island 'clade'.
Notes = References or reasons to overrule reconstructed assembly process of taxon.
Type = The reconstructed assembly process of each taxon.
