File List: The datasets named as "data_rumex_XXX.txt/csv" contain the data on Rumex lunaria. The datasets named as "data_urtica_XXX.txt/csv" contain the data on Urtica dioica. The datasets named as "data_salix_XXX.txt/csv" contain the data on Salix helvetica. The datasets named as "data_SPECIES_pop.csv" contain the data on the populations of the species Rumex lunaria, Urtica dioica or Salix helvetica. The datasets named as "data_SPECIES_indiv.txt" contain the data on ~150 individuals of each population referenced in "data_SPECIES_pop.csv" of the species Rumex lunaria, Urtica dioica or Salix helvetica. The datasets named as "data_SPECIES_leaf.txt" contain the data on the leaves of 10 males and 10 females from the individuals of the populations of the species Rumex lunaria, Urtica dioica or Salix helvetica. 2. Relationship between files, if important: the number of the populations refer to the same populations between the files of the same species. For example, the population one for Rumex lunaria refers to the same population one in the following documents "data_SPECIES_pop.csv", "data_SPECIES_indiv.txt" and "data_SPECIES_leaf.txt". 3.
