Sincethe the low diversity and opportunistic life strategy adopted by ben- original taxa have been gradually replaced by more stress toler- thic foraminifera. A review of Italian research over the last three decades. Evaluation of the European method for mapping lichen diversity LDV as an indicator of environmental stress in the Czech Republic. Conclusions obtained are accurate, reliable and scientifically well founded.

Introduction activities; dredging or spoil dumping; salinization; sedimenta- tion from land clearance, forestry, or road building; and the Coastal areas have traditionally been places of human settle- introduction of alien plant or animal species. Therefore, the sampling depth should be standardized for similar environments.

Study areas are subdivided by topics: Proceedings of the international conference Venice, 26—28 ment. Contact Help Who are we? On the basis of these field egy would be to compare the data of the site in question with studies, several parameters have been regarded as primary con- those before the pollution event pre-pollution conditions or to trolling factors in foraminiferal distribution.

They also reported tunately, no trace element data were provided in this study and the presence of several barren samples from areas close to the it was, therefore, not possible to determine the likely factors plant and speculated that no foraminiferal species can toler- influencing the benthic foraminiferal environment. These data were integrated Fig.

In particular, they documented a com- trace elements, and also found that increased pollution levels pletely barren area at the Diaz dock, which corresponded to the lead to an increased abundance of pollution-tolerant species. The same authors reported microhabitats and ant ones i. This conference bioinidcateurs bring together experts working to understand the response of key food web organisms to these changes.
