  • Quote that 87% of non-native terrestrial invertebrates in Europe are insects
    • whilst true, given that 80% of invertebrates are insects, it\’s not surprising!
    • it certainly helps their story though
  • essentially a literature review
    • each study was classified by reproducibility — as in, enough good information to calculate costs
    • as opposed to quality, as they say there\’s no objective, standard methodology for this
    • this is a good reason to develop this!
  • they discuss that regional relative costs are most likely a function of research effort, as opposed to actual differences in cost
  • the costs are most likely gross underestimates
    • due to limited studies and poor coverage in under-developed countries
  • total cost estimate of USD\$70 billion/year
