Pteropoda, Cladocera, and Chaetognatha associations as hydrological indicators in the southern Brazilian Shelf Asociaciones de Pteropoda, Cladocera y Chaetognatha como indicadores hidrológicos de la plataforma del extremo sur de Brasil
Associations of pteropod, cladoceran, and chaetognath species were analyzed for the southern coast of Brazil in order to present a biological diagnosis of the oceanographic conditions in winter and summer. The density data from the different species were analyzed using nodal and ordination cluster t...

Associations of pteropod, cladoceran, and chaetognath species were analyzed for the southern coast of Brazil in order to present a biological diagnosis of the oceanographic conditions in winter and summer.
