- Quote that 87% of non-native terrestrial invertebrates in Europe are
- 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
