    Density and depth variations of Daphnia multilocus genotypes during a summer period in Lake Maarsseveen

    The genotype composition of a Daphnia population complex during a summer period in Lake Maarsseveen (The Netherlands) was determined by allozyme analysis. The depth distribution, diel vertical migration and sever...

    What goes down must come up: symmetry in light-induced migration behaviour of Daphnia

    During a short period of the year, Daphnia may perform a phenotypically induced diel vertical migration. For this to happen, light-induced swimming reactions must be enhanced both at dawn and at dusk. Enhanced sw...

    On the combined analysis of proximate and ultimate aspects in diel vertical migration (DVM) research

    Although evolutionary ecologists agree that proximate and ultimate aspects are two sides of one coin, they are seldom interested in studies on physiological and behavioural mechanisms at the base of ecological...

    Quantitative effects of fish kairomones and successive light stimuli on downward swimming responses of Daphnia

    Swimming in response to light change is considered the proximate mechanism underlying diel vertical migration. This behavioural mechanism is supposed to be tuned to the adaptive needs under natural conditions ...

    Light-induced swimming of Daphnia: can laboratory experiments predict diel vertical migration?

    Vertical displacement velocity of a Daphniagaleata × hyalina clone was quantified inrelation to changes in the relative rate of lightchange. An increase in the latter variable triggers anenhanced swimming resp...

    Metapopulation dynamics of a persisting predator–prey system in the laboratory: time series analysis

    The scarcity of experimental evidence for the persistence of predator–prey systems at the metapopulation level inspired us to develop a simple predator–prey experiment that could be used for testing several th...
