Competitive ability depends on mating system and ploidy level across Capsella species.

There are three datasets corresponding to this article.


1) GreenHouse_2017_data.csv

Competition experiment in green house conditions.
- accession: internal code for the "accession" (seeds from a single individual collected in the field)
- species: Cbp: C. bursa-pastoris, Cg: C. grandiflora, Co: C. orientalis, Cr: C. rubella
- population: population name for Cbp: ASI: Asia, EU: Europe, ME: Middle-east, for other species there is no population attribution so the species code is used
- treatment: competition or alone
- block: block number
- survival: 1: alive, 0: dead
- flowering: 1: flowered, 0: did not flower
- flowernumber: total number of flowers of the individual
- alphaflowernumber: competition index for flower number: number of flowers of the individual divided by the number of flowers of the control individual: same accession in the same block grown alone
- germinationrate: germination rate of the accession measured before the experiment, so the same for all treatments and blocks.
- squarediameter1: product of the largest and smallest diameters of the rosette at time t1
- squarediameter2: product of the largest and smallest diameters of the rosette at time t2
- alphadiameter1: competition index for square diameter 1 (computed as for flower number)
- alphadiameter2: competition index for square diameter 2 (computed as for flower number)
- squaregrowthrate: (squarediameter2 - squarediameter1)/squarediameter1
- alphagrowthrate: competition index for growth rate (computed as for flower number)
