Potential challenges to conservation outcomes caused by language barriers.
Fig 1.
Language diversity among bird distributions.
(a) Number of official languages within the distributions of all bird species (n = 10,863), threatened species (n = 1427) and migratory species (n = 1939). (b) Number of official languages spoken in the distributions of bird species by threat category (as assessed by the International Union for Conservation of Nature). See S2 Fig for data on the most spoken language in each country.
Fig 2.
(a) Relationship between bird species’ distribution range size and the number of official languages within their distribution. International Union for Conservation of Nature (IUCN) threat categories are shown in different colours. Number of official languages spoken within each species’ distribution by (b) migratory status and IUCN threat categories, and by (c) taxonomic order. See S3 Fig for the same figure but based on the most spoken language in each country.
Fig 3.
Species richness of birds associated with each of the top six official languages with the highest number of species.
See https://translatesciences.shinyapps.io/bird_language_diversity/ for the results of other languages. Earth and countries outline were obtained from the Natural Earth public domain map dataset (http://www.naturalearthdata.com/).
Fig 4.
Bivariate maps showing the number of species (species richness) and the mean number of languages within the distribution of species found within each 30km × 30km grid cell for (a) all bird species, (b) threatened bird species, and (c) migratory bird species. The number of languages within each species’ distribution was calculated using the official languages in each country. See S5 Fig for the same figure but using the dataset of the most spoken language in each country. Earth and countries outline were obtained from the Natural Earth public domain map dataset (http://www.naturalearthdata.com/).
