Data from: Genetic variation in blue whales in the eastern Pacific: implication for taxonomy and use of common wintering grounds
Many aspects of blue whale biology are poorly understood. Some of the gaps in our knowledge, such as those regarding their basic taxonomy and seasonal movements, directly affect our ability to monitor and manage blue whale populations. As a step towards filling in some of these gaps, microsatellite...
