For each paper, 15 categories were used to collect relevant data. See tab: ‘List of papers’ for the included papers, tab: ‘Data’ for the categories from each paper, and tab: ‘Categories’ for the explanation of abbreviations used for each category. The full explanation of each category and methodology of paper selection is provided in Chapter 3 of the thesis: ‘Investigating the role of traits in species in marine and terrestrial ecosystems’. Data collected: January 2021 The following secondary dataset was used to support Chapter 3 of the thesis This secondary data was extracted from two GIS layers which were sourced from the Czech Hydrometeorological Institute (https://www.chmi.cz/). It consists of average rainfall across Czechia between 1986 and 2000 and average temperature across Czechia between 1986 and 2000 Data extracted from GIS layers: April 2021 ALM was supported by the Natural Environment Research Council (Grant number NE/L002531/1) and a School of Biological Sciences Studentship at the University of Southampton.
