Short review: Is bull-kelp kelp? The role of common names in science

摘要

Common names are non-specific by definition, and scientists should naturally avoid placing strict rules on their usage. There are many examples of common names applying to numerous, often only distantly related taxa, yet the term 'kelp' is increasingly being used to refer solely to members of the macroalgal order Laminariales, and some scientists now assert that any other use is incorrect. A brief examination of the word's etymology, however, demonstrates that kelp can with equal validity also refer to non-laminarialean taxa. Many people do still use the word 'kelp' in its broader sense, and these conflicting definitions of the word can lead to confusion and miscommunication between scientists and the general public. This review demonstrates that the definition of 'kelp' should remain relaxed, in accordance with its role as a common name. © 2012 The Royal Society of New Zealand.
