Plankton
Biology; Marine biology
Pelagic organisms that float through the water column, not attached to any substrate and unable to move against the currents and tides. Plankton can be further divided into phytoplankton and ...
Logistic population growth
Biology; Marine biology
Population growth that is modulated by the population size relative to carrying capacity. Population growth declines as population approaches carrying capacity, and is negative when population size ...
Global warming
Biology; Marine biology
Predicted increase in the earth's oceanic and atmospheric temperature, owing to additions of carbon dioxide to the atmosphere, as a result of human activities.
Mixoplankton
Biology; Marine biology
Planktonic organisms that can be classified at several trophic levels. For example, some ciliates can be photosynthetic but also can ingest other plankton and are heterotrophic.
Detritus
Biology; Marine biology
Particulate material that enters into a marine or aquatic system. If derived from decaying organic matter it is organic detritus. See also detrivore.
Directional selection
Biology; Marine biology
Preferential change in a population, favouring the increase in frequency of one allele over another.
Megaplankton
Biology; Marine biology
Planktonic organisms that are greater than or equal to 2000 micrometres in size.
