LANGUAGE ENDANGERMENT: USING ANALYTICAL METHODS FROM CONSERVATION BIOLOGY TO ILLUMINATE LOSS OF LINGUISTIC DIVERSITY

Language endangerment: Using analytical methods from conservation biology to illuminate loss of linguistic diversity

Language diversity is under threat, with between a third to a half of all languages considered endangered, and predicted rates of loss equivalent to one language per month for the rest of the century.Rather than reviewing the extensive body of linguistic research on endangered languages, this review focuses specifically on the interdisciplinary tra
