Fig. 6 — a Share of intercontinental trade of live poultry by exporting continents or country from 1962 to 2019. Export between 1962 and 1985 is based on the trade data of live fowls at in Observatory of Economic Complexity database. Export between 1986 and 2019 is based on the trade of live chickens (Gallus domesticus) and guinea fowls (Numida meleagris) according to the Food and Agriculture Organization of the United Nations. b Cumulative intercontinental export of live poultry originated from Europe and the US between 1962 and 2019. Forty-six importers represented by isolates in the phylogenetic analysis (Fig. 4) are shown. Cumulative trade volumes between $24 million (Belgium) and $754 million (China mainland) are designated with pie charts showing the comparisons between total import values from Europe and from the US. The sizes of the pie charts are proportional to the volumes of trade.
