Tintinnid species-specific assemblages show a coherent distributional pattern and well defined environment-related trends; most clearly differentiated preferences are exhibited by Laackmanniella prolongata (closely associated with ice-covered areas), Cymatocylis affinis/convallaria (oligotrophic open-ocean waters), and Codonellopsis balechi (coastal regions).
Patterns in tintinnid species composition and abundance in relation to hydrological conditions of the southwestern Atlantic during austral spring

Tintinnid abundances and species structure reflected the degree of variability in the hydrological conditions of the southwestern Atlantic between 1994 and 1995 and was reflected in a quite similar tintinnid community structure during these 2 years.

Comparisons with similar Weddell andWeddell-Scotia data retrieved in February-March 1987 and November 1988-December 1989 are highly coherent in terms of microplankton abundances, their geographic and vertical distribution patterns, and the specific make-up and distribution of tintinnid assemblages.
