Abstract
In a recent paper, Clarke & Warwick (1998; Oecologia 113: 278-289) developed a method of quantifying the complementarity of species assemblages, and demonstrated that in some marine benthic communities the redundancy in community composition was remarkably high. The concept of structural and functional redundancy was tested using macrobenthic species abundance data from different environments, the Valli di Comacchio and the Sacca di Goro, 2 northern Adriatic eutrophic lagoons. Samples were collected at approximately seasonal intervals: the Comacchio data set spanned from November 1996 to January 2000, while the Goro data set from January 1993 to December 1998. The level of structural redundancy in such habitats was quite low, while functional redundancy seemed higher. These findings are probably of great importance for the conservation and management of such habitatsI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
