Temporal variation in vitamin B12 concentration and their impact on phytoplankton composition of surface waters of a coastal ocean off Japan (Ariake Sea)
Most phytoplankton, including harmful algal bloom (HAB)-forming species, have an absolute requirement for vitamin B 12 (cobalamin). However, the...

Long-term variability in larval recruitment rates of a callianassid shrimp population on an intertidal sandflat in an estuary-to-coastal ocean interface area in relation to river discharge and shelf water movement, western Kyushu, Japan
Food availability is believed to affect macro-invertebrate larval survival at sea, which was poorly demonstrated. On the coast immediately outside an...
