Societal attention toward extinction threats: a comparison between climate change and biological invasions

摘要

Climate change is a more salient threat on Internet than invasive alien species; both threats are also better recognized for threatened species within the country than elsewhere in Europe and in the world. Relative Internet salience of climate change and invasive alien species in relation to threatened species from United Kingdom, France and Germany, as well as to other threatened species of these groups, present elsewhere in Europe and in the world (noted in figure as national, European and global, respectively). Relative Internet salience was expressed as the mean number of webpages retrieved by Internet search within each of the countries for the scientific name of a species and the particular threat, divided by the number of webpages retrieved by searching for the scientific name only.
