Abstract: The quantitative and qualitative contents of
a zooplankton sample are influenced by two
kinds of variables: (1) natural variables such as
temperature of the water, currents, latitudinal
and seasonal variations in sunlight intensity,
water transparency, amount of food or nutrients,
oxygen content of the water, which may
modify or maintain the horizontal and vertical
distribution of species and condition their breeding
and growth cycles; (2) artificial variables
associated with (a) the method used to present
the data, (b) the method used to take aliquots
and count the plankton, and (c) the collecting
method-type of net, depth of tow, hour of day
of sampling.
