Photosynthetic picoplankton - Wikipedia
Photosynthetic picoplankton or picophytoplankton is the fraction of the photosynthetic phytoplankton of cell sizes between 0.2 and 2 μm (i.e. picoplankton). It is especially important in the central oligotrophic regions of the world oceans that have very low concentration of nutrients .
Picophytoplankton - an overview | ScienceDirect Topics
Picophytoplankton generally dominate primary production in offshore, oligotrophic systems, and can also be important in coastal systems on a seasonal basis. For instance, picoplankton averaged 71% of photosynthetic biomass and 56% of primary production during four Atlantic Ocean cruises (50° N–50° S) crossing coastal, upwelling, and central ...
超微型浮游植物（Picophytoplankton）: 沿海海洋变化的先兆
超微型浮游植物，原绿球藻和聚球藻，是小型（直径<2微米）的光合蓝藻细菌，为世界上的开放海洋贡献了大部分初级生产力（Worden等人，2004）。 这两个属都生活在特定的生态位。 原绿球藻生长在营养成分少，光照充足，温暖的热带水域，对沿海水域不耐受。 相反，聚球藻分布在亚热带地区，在营养丰富浊度较高的上升流地区或沿海地区最丰富。 由于其体积很小，超微型浮游植物的表面积与体积之比很大，这使得它们与周围的海水有着密切的接触。 这就使得细胞能够快速 …

Picoplankton - Wikipedia
Picoplankton is the fraction of plankton composed by cells between 0.2 and 2 μm that can be either prokaryotic and eukaryotic phototrophs and heterotrophs: They are prevalent amongst microbial plankton communities of both freshwater and marine ecosystems.

Picoplankton (<2mm) are the largest component of the phytoplankton biomass and primary production, contributing 39%–82% of total chlorophyll in the oceanic Coral Sea (Furnas & Mitchell, 1996).

The picophytoplankton comprises small (size range: 0.2 µm to 2 µm) prokaryotic picocyanobacteria and eukaryotic phototrophs. They are distributed worldwide and are ubiquitous in all types of lakes and ocean, of varying trophic state (Stockner & Antia, 1986).
