Planktonic organisms exhibit diverse morphological, behavioural and life-history responses
to the chemical presence of potential predators. Prey organisms have been found to sense …

Phenotypic plasticity is a key factor for the success of organisms in heterogeneous
environments. Although many forms of phenotypic plasticity can be induced and retracted …

This review focuses on monospecific swarms of four taxonomic groups of small crustaceans:
three groups are marine copepods: oithonids (Oithona and Dioithona), Acartia species and …

Literature on local genetic differentiation in freshwater zooplankton populations is reviewed.
The island-like nature of limnetic habitats creates opportunities for local genetic …

In contrast to the numerous studies that have examined the response of predators to prey
group size, little is known about how prey density affects prey detection and the accuracy of …

We extend our study of single and collective motions of the zooplankton Daphnia both in
experiment and computer simulation. Daphnia, as well as many other prey animals, can be …

Daphnia magna can respond to chemical cues from freshly crushed conspecifics with
various behavioural reactions. A shift in vertical distribution towards the bottom, the …

Using an individual-based age-structured population model (a combination of O'Brien's
apparent-prey-size approach, Eggers's reactive-field-volume model, and Holling's disk …

In aquatic systems, the phytoplankton-zooplankton relation is of major importance because it
is the first step in the pelagic food chain. It is well known that zooplankton feed with a highly …

The behavioural response of the freshwater zooplankter Daphnia to chemicals from its food,
the green alga Scenedesmus, to algal cells, to the green colour from chlorophyll, to …
