Associated publication: Barouillet et al. Paleoreconstructions of ciliate communities reveal long-term ecological changes in temperate lakes This table contains information about the ecology of ciliates used in our study. Each raw correspond to a unique taxonomic entry obtained from our metabarcoding dataset. The association of each taxonomical entry to their functional traits was done through an exhaustive literature review, the list of reference can be found in the second page of the excel document. The foraging traits categories created were inspired from a combination of several previously published categories based on the feeding ecology of ciliates developed by Weisse (2017), Foissner and Berger (1996), Foissner et al. (2008) and Beaver and Crisman (1989). References: Weisse, T. Functional diversity of aquatic ciliates. European Journal of Protistology 61, 331–358 (2017) Foissner, W. & Berger, H.
