Fig. 5: Invasive spread of marbled crayfish on Madagascar.
From: Clonal genome evolution and rapid invasive spread of the marbled crayfish
a, Representative genotyping results of 24 animals collected on four distinct collection sites. The heatmap indicates sequence similarities with the marbled crayfish reference sequence. P. fallax and P. alleni were included as controls. Cyt b, cytochrome b; SNPs, single-nucleotide polymorphisms. b, Marbled crayfish by-catch in a traditional fishing tool or 'tandroho'. c, Distribution of marbled crayfish on Madagascar (as of March 2017) in major biogeographical zones55, as indicated. Red dots indicate discovery sites where the presence of marbled crayfish was confirmed by DNA sequencing. White dots indicate sites where no marbled crayfish were found. The small central yellow circle indicates the distribution range reported for the year 2007 (ref. 9).
