all introductions (solid bars) or only those leading to successful establishment (open bars)

Within the 12 regions examined, eight have received introductions representa-
tive of all six major pathways, two have five pathways represented, and only two
have as few as four pathways (Fig. 2.29). For most regions, introductions are domi-
nated by only one or two pathways, but pathway importance varies between
regions. Single pathways accounting for >50% of all introductions within a recipi-
ent region include the pet trade in Europe, North America, the Atlantic Islands,
South America, and Asia, and cargo in Australia and the Pacific Islands (Fig. 2.29).
