Data from Martorell et al. 2021 Plant soil feedbacks depend on drought stress, functional group and evolutionary relatedness in a semiarid grassland. Ecology.<br><br><br>ERSPhist contains the historic data of each subquadrat<br>ERSPlong contains the longevities of all plants<br><br>IN BOTH FILES:<br>Lugar: name of the site where the experiment was conducted (4 sites)<br>Cuadro: quadrat identifier<br>Cuadrito: Subquadrat identifier.

For istance, Sanpro2013 has the abundances of S. procumbens in 2013.<br>Prof: Soil depth, in cm<br>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.<br><br>IN ESRPlong FILE<br>“long” variables report lingevity in days for each species<br>“cens” variables indicate whether longevity was censored. 1 = censored (beware: many statistical programs use the opposite code)
