Ma. Leibold et Ct. West, EXPERIMENTAL METHODS FOR MEASURING THE EFFECT OF LIGHT ACCLIMATION ONVERTICAL MIGRATION BY DAPHNIA IN THE FIELD, Limnology and oceanography, 38(3), 1993, pp. 638-643
A new method is developed and tested for measuring vertical migration
behavior by zooplankton in the field by means of acrylic columns with
conical traps. Migration behavior in columns by different species and
by different individuals of the same species is similar to migration b
ehavior in the lake. We further show that acclimation to light intensi
ty can be a factor in determining the amplitude of vertical migration
in Daphnia pulicaria.
