Fig. 4From: Does the growing of Bt maize change abundance or ecological function of non-target animals compared to the growing of non-GM maize? A systematic reviewDistribution of non-target invertebrate records in the database (articles, experiments, Bt proteins, countries). A records per article (each bar represents one article), B records per experiment, C Bt protein produced by the studied Bt-maize line grouped by target order (Lepidoptera-active in blue, Coleoptera-active in green, Lepidoptera- and Coleoptera-active in turquoise), and D countries where the experiments were conducted (different colours indicate continents). Within panels (C) and (D), the number of experiments associated with each bar is given. Note the log-scaleBack to article page
