In Buenos Aires province, the river Samborombón, which is typical of the plain, was sampled monthly during 1986-1987 in research carried out both on its physico-chemical characteristics and the communities present - plankton, phytobenthos, zoobenthos -. In this paper the structure and function of phytoplankton and benthic algal communities in the different sections of the river are compared. Both communities have definite limits as their components are not shared and show different strategies. Likewise, the environmental conditions along the river are variable, leading to differences in the planktonic and benthic algae at the locations studied.
Résumé
Dans la province de Buenos Aires, la rivière Samborombón, rivière typique de plaine, a été étudiée de mars 1986 à février 1987 dans le cadre d'une recherche relative aux caractéristiques physico-chimiques et aux communautés du plancton, du phytobenthos et du zoobenthos. Dans ce travail, la structure et la fonction du phytoplancton et du phytobenthos sont comparées dans diverses sections de la rivière. Les communautés ont des limites définies parce que leurs composantes sont différentes et montrent des stratégies contraires. Les caractéristiques du milieu sont variables tout au long de la rivière et déterminent des variations locales.
