Data from: Weed diversity is driven by complex interplay between multi-scale dispersal and local filtering

The dataset gathers information on the 444 arable fields and associated weed communities studied in the research article Weed diversity is driven by complex interplay between multi-scale dispersal and local filtering by Bourgeois, B., Gaba, S., Plumejeaud, C. and Bretagnolle, V., published in Proceedings of the Royal Society B:Biological Sciences.

Data include:

• FieldID : unique identifier of the sampled field
• Crop Type : type of annual crop cultivated in the sampled field
• Sampling Year : year of weed community survey
• Gamma field : richness of weeds in the entire field
• Gamma field core : richness of weeds in field core
• Alpha field core subplot : mean weed richness of field core subplots
• Beta field core subplot : ratio of the mean weed richness between subplots of the same field core plot over the richness of the field core plot
• Beta field core plot : ratio of the mean weed richness between field core plots over the weed richness of the field core
• Beta field core-field margin : ratio between Gamma field core and Gamma field
• Gamma field margin : richness of weeds in field margin
• Alpha field margin subplot : mean weed richness of field margin subplots
• Beta field margin subplot : ratio of the mean weed richness between subplots of the same field margin plot over the richness of the field margin plot
• Beta field margin plot : ratio of the mean weed richness between field margin plots over the weed richness of the field margin
• Beta field margin-field core : ratio between Gamma field margin and Gamma field
