# *******************************************************************************************************************************************# MOSCOSA FARM DATASET A 2500 m^2 study plot, located in an Iberian dehesa meadow on granite soils, was surveyed at La Mina in Moscosa Farm, Salamanca, Spain (41º8'21.88''N, 6º6'52.33''W). The presence-absence of plant species was surveyed using a centric systematic area-sample design with n = 196 sample units (1-m^2 quadrats). The first 123 columns in the dataset correspond to a species matrix of n = 196 sample units x p = 123 species, where each element represents the presence (1) / absence (0) of each species. The next two columns in the dataset (X, Y) correspond to the Cartesian coordinates that identify sample units (spatial matrix). The last column is an environmental vector of n = 196 sample units x q = 1 hydrological descriptor (AWTD), where each element is the value of the descriptor at each sampling unit. The additional species list details species names and their taxonomic families, together with their geographic distribution and Raunkiaer life-form. Quantity (units) Description X (m) Cartesian coordinate specifying the central position of n = 196 sample units (1-m^2 quadrats) in the field plot Y (m) Cartesian coordinate specifying the central position of n = 196 sample units (1-m^2 quadrats) in the field plot AWTD (m) (a) Average Water Table Depth at a sample unit over the growing season (a) The origin is taken at the ground surface with a positive downwards direction, hence AWTD values are positive. # *******************************************************************************************************************************************#
