Calcareous and siliceous species on calcareous and siliceous soils over four years of reciprocal transplant experiments

This dataset is a collection of data from 4-year experiments conducted in
the Gironde department in southwestern France. It contains “Block, Year,
Soil type, neighboring, Species and Origin” as explanatory categorical
variables and “Target survival” as binomial response variable. These data
were analyzed in order to characterize and assess how the effect of
species stress tolerance and community competitive effects lead to
differences in species composition between calcareous and siliceous plant
communities. The year, rock and origin variables and their interactions as
fixed factors, were used to assess the effect of abiotic conditions of the
soil type and year quality, on the survival of target species from
calcareous and siliceous soils growing without neighbors, using a general
linear mixed-effects model with a logit link function for binomial
distribution. The survival with and without neighbours was also used to
calculate two indices to characterize the intensity (RII) and the
importance (Iimp) of plant-plant interactions. RII and Iimp were then
analyzed separately using linear mixed-effects models with “Year quality”,
“Soil type”, “Origin” and their interactions as fixed factors and “Year
nested within Blocks” as a random factor. All data were stored using
Microsoft Excel and all the statistical analyses were done using R
software (R Core Team 2016).
