ERSPhist.csv

Data from Martorell et al. 2021 Plant soil feedbacks depend on drought stress, functional group and evolutionary relatedness in a semiarid grassland. Ecology.

ERSPhist contains the historic data of each subquadrat
ERSPlong contains the longevities of all plants

IN BOTH FILES:
Lugar: name of the site where the experiment was conducted (4 sites)
Cuadro: quadrat identifier
Cuadrito: Subquadrat identifier. Letter and number corresponds to coordinates in a 10 x 10 lattice

Other variable names contain the name of the species involved:
Ariads: Aristida adscensionis
Boucho: Bouteloua chondrosioides
Bouhir: Bouteloua hirsuta
Crudiv: Crusea diversifolia
Digbic: Digitaria bicornis
Hetpin: Heterosperma pinnatum
Hilcen: Hilaria cenchroides
Mickun: Microchloa kunthii
Muhpha: Muhlenbergia phalaroides
Planiv: Plantago nivea
Sanpro: Sanvitalia procumbens
Steeph: Stevia ephemera
Tagmic: Tagetes micrantha
Thyaur: Thymophylla aurantiaca
Tricor: Tridax coronopifolia
Tripur: Tripogandra purpurascens
Trispi: Tripogon spicatus

IN ERSPhist FILE
variables with numbersd: indicate the abundance of different species in different years. For istance, Sanpro2013 has the abundances of S. procumbens in 2013.
Prof: Soil depth, in cm
TRAT: Treatment. cont=Control; este= sterilized using heat. Data from this treatment were not used in the analyses. Its goal was to eliminate soil biota to have an idea on PSF mechanisms, but soil analyses revealesd that heating cause the mobilization of huge amunts of phosphorus, one of the most limiting nutrients at the study site. This makes it imposible to interpret the results of this treatment.

IN ESRPlong FILE
“long” variables report lingevity in days for each species
“cens” variables indicate whether longevity was censored. 1 = censored (beware: many statistical programs use the opposite code)
