Country characteristics and non-indigenous species

Gren, Ing-Marie; Berglund, Helena; Nilsson, Fredrik


This paper carries out an econometric test of two hypotheses underlying occurrences of non-indigenous species (NIS); openness of the recipient country which allows for international trade acting as a vector of NIS and biota change in recipient countries facilitating establishment of introduced NIS. Both hypotheses for NIS occurrences get support, but in different directions for continental and island countries. Another result is that the impacts of several explanatory variables exhibit a switch in the correlation with NIS at a certain level. It is also shown that the measurement of NIS occurrences in the countries affects the results.
