Editing Zooplankton (section)

===Mesozooplankton===
Mesozooplankton are one of the larger size classes of zooplankton. In most regions, mesozooplankton are dominated by [[copepods]], such as [[Calanus finmarchicus]] and [[Calanus helgolandicus]]. Mesozooplankton are an important prey for fish. 

As plankton are rarely fished, it has been argued that mesoplankton abundance and [[species composition]] can be used to study marine ecosystems' response to climate change. This is because they have life cycles that generally last less than a year, meaning they respond to climate changes between years. Sparse, monthly sampling will still indicate vacillations.<ref>{{Cite journal |last1=Mackas |first1=David L. |last2=Beaugrand |first2=Gregory |date=2010-02-10 |title=Comparisons of zooplankton time series |url=https://www.sciencedirect.com/science/article/pii/S0924796309000852 |journal=Journal of Marine Systems |series=Impact of climate variability on marine ecosystems: A comparative approach |language=en |volume=79 |issue=3 |pages=286–304 |doi=10.1016/j.jmarsys.2008.11.030 |bibcode=2010JMS....79..286M |issn=0924-7963}}</ref>
