Fig 3. The web search interest of vertebrates compared by Class and Extinction risk (IUCN Red List Status).

Fig 3

a) The average monthly web search interest for species with sufficiently high search volume for Google Trends to return data. b) The probability of a species having a sufficiently high search volume for Google Trends to return data. Bars represent means, error bars represent 95% confidence intervals. Graphs are derived from model predictions made using a negative binomial generalised linear model (a) and a binomial generalised linear model (b) where response = Class*Red List Status. Numbers in parenthesis represent the number of species in each Class*Red List Status combination. Numbers in bold define groups of Red List Status within each class that are significantly different at the 95% confidence level. Any two Red List Statuses within a Class that share a digit cannot be considered significantly different. Letters on the x axis of b denote each Red List Status classification (CR = Critically Endangered, EN = Endangered, VU = Vulnerable, NT = Near Threatened, LC = Least Concern, DD = Data Deficient).
