Abstract In this paper the spatial variation of zooplanktonic groups(cladocerans, rotifers, nauplii and adults of copepods) in the Broareservoir was studied using geostatistical tools. The variation inthe density of cladocerans and nauplii and adults of copepods isstructured along the geographic space in the form of gradients, whichimplies the rejection of the hypothesis of spatial homogeneity andrandomness. In other words, the variation in the density of thesegroups is not distributed randomly over the geographic space. Thepatterns of spatial variation observed can be attributed to differentfactors (advection, behavioral mechanisms and limnological factors).The last conclusion is congruent with the multiple forces hypothesis(Pinel-Alloul, 1995; Pinel-Alloul et al., 1995). Implications tosampling methodology are also discussed.
