The accompanying datafile "Figueiredo_EcologyLetters_SiderophoresDriveBacterialInvasions_Data" contains all the data used in Figueiredo ART, Özkaya Ö, Kümmerli R, and Kramer J (2021) Siderophores drive invasion dynamics in bacterial communities through their dual role as public good versus public bad, published in Ecology Letters This file provides an overview on the data and how they link to the above-mentioned paper Sheet: GRO_ResidentsInvader Data on the growth and pyoverdine production of residents and invader in monoculture [Fig. 1] habitat origin of resident (soil or pond) community ID of community from which focal resident originated condition level of iron-availability (CAAM = iron-limited;
