esults of this study will convey a revision of the taxonomic status of this species<br />

listed in Annex I of the EC Birds Directive, which is expected to result in the<br />

recognition of two distinct species with an increased vulnerable status, requiring<br />

immediate conservation measures.<br />

Regarding cetaceans, a database of the present populations of the different<br />

species will be compiled and the consequence of the increasing touristic<br />

pressure due to whale watching for the populations will be monitored. This is a<br />

recent activity in the Azores, but a large expansion is expected since it is the<br />

region in the North Atlantic with the highest diversity of cetaceans. A special<br />

importance is given to the resi<strong>de</strong>nt groups of Tursiops truncatus (species<br />

inclu<strong>de</strong>d in Annex II of the EC Habitats Directive). The data collected will be used<br />

in calculating the capacity load for the whale watching and in elaborating and<br />

implementing a complex of management measures, which could lead to the<br />

proposal of new protection areas.<br />

Concerning marine turtles, the present project will seek to supervise tagging,<br />

access the impacts of acci<strong>de</strong>ntal capture of turtles by the fishing fleet and study<br />

the distribution of the populations. The results of these studies will help in<br />

adopting practical measures for protecting the different species of turtles,<br />

especially the loggerhead (Caretta caretta), a priority species of the “Habitats<br />

Directive”, which has its nursery ground around the Azores on its migratory route<br />

in the North Atlantic.<br />

VENTOX – Deep-Sea hydrothermal vents: a natural pollution laboratory.<br />

UE – EVK3-CT1999-00003<br />

The VENTOX project is inten<strong>de</strong>d to un<strong>de</strong>rpin this important European<br />

en<strong>de</strong>avour by providing innovative insights into the long-term (i.e. evolutionary)<br />

adaptations of a unique group of organisms, the <strong>de</strong>ep-sea hydrothermal fauna<br />

(and associated microbes), which are unique amongst life on earth in having<br />

been exposed to high levels of environmental contamination (low pH, high CO 2,<br />

poisonous sulphi<strong>de</strong>s, heavy metals and hazardous radionucli<strong>de</strong>s) throughout<br />

their evolutionary history. Furthermore, vent species have shallow-water<br />

relatives that are important both in terms of biodiversity (community structure)<br />

and commercial exploitation (e.g. shellfish). The evolutionary adaptations and<br />

responses of vent species to their highly toxic and hostile environment are<br />

therefore extremely relevant to our un<strong>de</strong>rstanding of the short and long-term<br />

consequences of contaminant exposure in shallow-water marine ecosystems.<br />

The contaminant history of the <strong>de</strong>ep-sea vent fauna extends back to at least the<br />

Mesozoic (further in the case of vent bacteria); by comparison, anthropogenic<br />

pollution is only a very recent phenomenon (covering the past 100 years).<br />

Without such a long-term, evolutionary perspective on contaminant impact in<br />

marine ecosystems, it is not possible to consi<strong>de</strong>r the <strong>de</strong>velopment of truly viable<br />

long-term management strategies.<br />

The primary objective of this RTD proposal is to carry out innovative research<br />

into the specialised adaptations and processes found in representatives of the<br />
