Low worldwide genetic diversity in the basking shark ( Cetorhinus maximus)
The basking shark ( Cetorhinus maximus ) is found in temperate waters throughout the world's oceans, and has been subjected to extensive exploitation in some regions. However, little is known about its current abundance and genetic status. Here, we investigate the diversity of the mitochondrial...
