Abstract |
Human activities related to the sea have had significant impacts on all ecosystems and are
evident from coastlines and coastal areas to the depths of the oceans. The Marine
Strategy Framework Directive (MSFD) establishes a common approach among the
European Union member states for the prevention, protection, and preservation of the
marine environment from damages caused by human activities, while also allowing for
the use of the marine environment without disrupting the ecosystem itself.
Macrofauna is one of the indicators used by the MSFD to assess the good environmental
status of marine ecosystems. On the other hand, meiofauna is not currently considered in
monitoring programs although it possesses numerous characteristics that make it
potentially more effective than macrofauna. For this project meiofauna samples were
collected from thr deep sea of the Aegean sea and from the open-sea stations network of
the Greek MSFD, aiming to evaluate whether these organisms could serve as a suitable
tool for assessing the environmental status of deep-sea ecosystems in the eastern
Mediterranean.
Our results indicate a dominance of nematodes, particularly the genera Sabatieria and
Syringolaimus. Chlorophyll a and CPE values suggest an oligotrophic ecosystem,
(especially in the southern Aegean region) with reduced food quantity that decreases with
depth. Finally, the ecological status assessment using meiofauna as a tool indicates that
the sampled areas fall into the category of good ecological status. This study suggests that
meiofauna, particularly nematodes, is a useful tool for assessing the ecological status and
could be used as a complementary approach to macrofauna for monitoring the marine
environment under the Marine Strategy Framework Directive. However, further work and
research are required to understand which specific meiofauna characteristics are most
suitable for this purpose.
