In recent years, phytoplankton phenology has been proposed as an indicator to monitor systematically the state of the pelagic ecosystem and to detect changes triggered by perturbation of the environmental conditions. Here we describe the phenology of phytoplankton growth for the world ocean using remote...

[典例呈现]Phytoplankton live at the ocean surface, where theypull carbon dioxide(二氧化碳) into the ocean while giv-ing off oxygen. When these organisms die, they bury car-bon in the deep occan, an important process that helps toregulate the global climate. But phytoplankton are vul-nerable...
This migratory behaviour relaxes the boundaries between the fluid dynamic niches of motile and non-motile phytoplankton, and highlights that rapid responses to hydrodynamic cues are important survival strategies for phytoplankton in the ocean.

If ocean productivity were changing, these biological processes could have a significant influence on anthropogenic CO 2 levels by drawing down the CO 2 concentration in surface waters and increasing the concentration gradient across the air–sea interface 1,3,4 . The question of productivity changes...

Trypsin is best known as a digestive enzyme in animals, but remains unexplored in phytoplankton, the major primary producers in the ocean. Here we report the prevalence of trypsin genes in global ocean phytoplankton and significant influences of environm
