Picoplankton, the Glossary
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.[1]

Abundance (ecology)
In ecology, local abundance is the relative representation of a species in a particular ecosystem.
See Picoplankton and Abundance (ecology)
Bacterioplankton
Bacterioplankton refers to the bacterial component of the plankton that drifts in the water column. Picoplankton and Bacterioplankton are aquatic ecology, biological oceanography and Planktology.
See Picoplankton and Bacterioplankton
Biomass (ecology)
Biomass is the mass of living biological organisms in a given area or ecosystem at a given time.
See Picoplankton and Biomass (ecology)
Carbon cycle
The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth.
See Picoplankton and Carbon cycle
Cell (biology)
The cell is the basic structural and functional unit of all forms of life.
See Picoplankton and Cell (biology)
Ciliate
The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella.
Copepod
Copepods (meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat.
Flagellate
A flagellate is a cell or organism with one or more whip-like appendages called flagella.
See Picoplankton and Flagellate
Flow cytometry
Flow cytometry (FC) is a technique used to detect and measure the physical and chemical characteristics of a population of cells or particles.
See Picoplankton and Flow cytometry
Fluorescence microscope
A fluorescence microscope is an optical microscope that uses fluorescence instead of, or in addition to, scattering, reflection, and attenuation or absorption, to study the properties of organic or inorganic substances.
See Picoplankton and Fluorescence microscope
Heterotroph
A heterotroph is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter.
See Picoplankton and Heterotroph
International System of Units
The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement.
See Picoplankton and International System of Units
Lake ecosystem
A lake ecosystem or lacustrine ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (non-living) physical and chemical interactions. Picoplankton and lake ecosystem are aquatic ecology.
See Picoplankton and Lake ecosystem
Lysis
Lysis is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, "lytic") mechanisms that compromise its integrity.
Marine ecosystem
Marine ecosystems are the largest of Earth's aquatic ecosystems and exist in waters that have a high salt content. Picoplankton and Marine ecosystem are aquatic ecology and biological oceanography.
See Picoplankton and Marine ecosystem
Marine microorganisms
Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. Picoplankton and marine microorganisms are biological oceanography and Planktology.
See Picoplankton and Marine microorganisms
Metric prefix
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit.
See Picoplankton and Metric prefix
Microbial loop
The microbial loop describes a trophic pathway where, in aquatic systems, dissolved organic carbon (DOC) is returned to higher trophic levels via its incorporation into bacterial biomass, and then coupled with the classic food chain formed by phytoplankton-zooplankton-nekton.
See Picoplankton and Microbial loop
Mixotroph
A mixotroph is an organism that can use a mix of different sources of energy and carbon, instead of having a single trophic mode on the continuum from complete autotrophy at one end to heterotrophy at the other.
See Picoplankton and Mixotroph
Oligotroph
An oligotroph is an organism that can live in an environment that offers very low levels of nutrients. Picoplankton and oligotroph are aquatic ecology.
See Picoplankton and Oligotroph
Photic zone
The photic zone (or euphotic zone, epipelagic zone, or sunlight zone) is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. Picoplankton and photic zone are aquatic ecology.
See Picoplankton and Photic zone
Photopigment
Photopigments are unstable pigments that undergo a chemical change when they absorb light.
See Picoplankton and Photopigment
Photosynthesis
Photosynthesis is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
See Picoplankton and Photosynthesis
Phytoplankton
Phytoplankton are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. Picoplankton and Phytoplankton are aquatic ecology, biological oceanography and Planktology.
See Picoplankton and Phytoplankton
Picocyanobacteria
Picocyanobacteria are cyanobacteria that are part of the picoplankton, which is the fraction of plankton composed by cells between 0.2 and 2 μm. Picoplankton and Picocyanobacteria are aquatic ecology, biological oceanography and Planktology.
See Picoplankton and Picocyanobacteria
Picoeukaryote
Picoeukaryotes are picoplanktonic eukaryotic organisms 3.0 μm or less in size. Picoplankton and Picoeukaryote are aquatic ecology, biological oceanography and Planktology.
See Picoplankton and Picoeukaryote
Picozoa
Picozoa, Picobiliphyta, Picobiliphytes, or Biliphytes are protists of a phylum of marine unicellular heterotrophic eukaryotes with a size of less than about 3 micrometers.
Plankton
Plankton are the diverse collection of organisms that drift in water (or air) but are unable to actively propel themselves against currents (or wind). Picoplankton and Plankton are aquatic ecology, biological oceanography and Planktology.
Primary production
In ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide.
See Picoplankton and Primary production
Protozoa
Protozoa (protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris.
Rotifer
The rotifers (from the Latin rota, "wheel", and -fer, "bearing"), commonly called wheel animals or wheel animalcules, make up a phylum (Rotifera) of microscopic and near-microscopic pseudocoelomate animals.
Trophic level
The trophic level of an organism is the position it occupies in a food web.
See Picoplankton and Trophic level
Zooplankton
Zooplankton are the animal (or heterotrophic) component of the planktonic community (the "zoo-" prefix comes from), having to consume other organisms to thrive. Picoplankton and Zooplankton are biological oceanography and Planktology.
