<p>This is the dataset from: Sotomayor DA and Lortie CJ. 2015. Indirect interactions in terrestrial plant communities: emerging patterns and research gaps. Ecosphere 6(6): art103.<br>Methods<br>This dataset corresponds to a systematic review on inidirect interactions in terrestrial plant communities which captured the literature published between 1990 and July 2014 using the ISI Web of Science (WoS), Scopus, and Google Scholar. The following keywords were used: "indirect", "plant", "interaction", "competition", "facilitation". The first three words were used together in combination with the last two words in separate queries (i.e. indirect* plant* interaction* competition OR indirect* plant* interaction* facilitation).<br>The initial serach yielded 490 research articles obtained from the WoS, which were screened in order to assess their relevance. Searches in both Scopus and Google Scholar were conducted to complement the WoS search. The following inclusion criteria were used: (1) studies explicitly dealing with indirect interactions in terrestrial ecosystems (i.e. 3 or more species reported in the interaction); (2) studies describing the results of experiments specifically designed to test effects of indirect interactions versus proposals of indirect interactions in discussion; and (3) primary empirical research reported (i.e., not reviews). Papers complying with these criteria were processed to extract data on (1) type of interaction tested; (2) number of species tested as targets, where target is defined as the species on which measurements of performance were taken; (3) role of the species involved in the interaction considering not only target species, but also species that were removed or mentioned by the authors as members of the interaction; (4) type of experiment and number of field sites; (5) type of ecosystem and geographical location of the study; and (6) type of measurements and statistical analysis performed.</p> <p> </p>
