SpatialModelHistogram.csv

Frequency distribution of depth-averaged flow velocities within vegetated and unvegetated cells of the simulated domain (from the spatial model).
FlowVelocity: Simulated flow velocity (m/s)
N. of cells: Number of cells in the simulated arena with a certain flow velocity
CellType Cell type (vegetated/unvegetated)

HomogeneousCoexistenceModel.m

Non-spatial version of the model. The code is used to predict the outcome of interaction between facilitator and beneficiary species under homogeneous conditions and to create the graph in Figure 2D.

Berula_Flevieu.txt

Spatial distribution of Berula erecta vegetation in the Flevieu site. Pixels values are 0 if the species is absent, or they show the value of the blue channel in the RGB image where the species is present.

Callitriche_Flevieu.txt

Spatial distribution of Callitriche platycarpa vegetation in the Flevieu site. Pixels values are 0 if the species is absent, or they show the value of the blue channel in the RGB image where the species is present.

Groenlandia_Serrieres.txt

Spatial distribution of Groenlandia densa vegetation in the Serrieres site. Pixels values are 0 if the species is absent, or they show the value of the blue channel in the RGB image where the species is present.

Callitriche_Serrieres.txt

Spatial distribution of Callitriche platycarpa vegetation in the Serrieres-de-Briord site. Pixels values are 0 if the species is absent, or they show the value of the blue channel in the RGB image where the species is present.

Transplant_N		: Identification code for the transplanted individual

SpacerLength.csv

Data on spacer length (distance between consecutive individuals produced through vegetative reproduction). 
BeneficiarySpecies	: Beneficiary species in the transplantation experiment
Position			: Position of the transplant around the Callitriche patch
SpacerLength		: Distance (in cm) between consecutive individuals in the clone
AverageVelX		: Depth-averaged flow velocity (m/s)

DaughterRametDM.csv

Dry mass of daughter ramets produced by the transplants through vegetative reproduction. 
BeneficiarySpecies	: Beneficiary species in the transplantation experiment
Transplant_N		: Identification code for the transplanted individual
FacilitatorPatch	: Identification code for the facilitator (Callitriche) patch
Position			: Position of the transplant around the Callitriche patch
DaughterRamet_DM	: Daughter ramet dry mass (g)
AverageVelX		: Depth-averaged flow velocity (m s-1)
