Abstract
Four taxonomic benthic biotic indices (AMBI, BENTIX, Engle's and Paul's B-IBIs) were used to analyse benthic assemblages in two transitional water ecosystems: Pialassa Baiona, northern Adriatic Sea, and Varna lake, Black Sea. The environmental quality assessments provided by the different indices is not consistent with the patterns of environmental quality of the investigated sites. Moreover, these indices provide ambiguous information on effects of sea-land gradient and/or anthropogenic disturbance on transitional ecosystems. In transitional waters, ecological classification based on biotic indices requires an adjustment for the reference conditions, environmental features and habitat typologies. © 2007 University of Salento - SIBA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
