Distribution and species-specific egg production of Pseudocalanus in the Gulf of Alaska
Pseudocalanus species are important contributors to the secondary production of the northern hemisphere mid- to high-latitude oceans. In the coastal Gulf of Alaska, Pseudocalanus are present year round and are represented by three species. In 2001, Pseudocalanus mimus was the dominant Pseudocalanus...
