The last annotated checklist of marine polychaetes in Greece was published 2001. Since then, global taxonomic progress, combined with many new species records for Greece, required a thorough review the taxonomic, nomenclatural and biogeographic status national list. This revises all extant polychaete reported from Greek Exclusive Economic Zone since 1832. work undertaken as part efforts on compiling inventory (Greek Taxon Information System initiative) framework LifeWatchGreece Research...

A methodology is presented to assess the environmental status sensu Marine Strategy Water Framework Directive (MSFD) based on data obtained from monitoring of water quality in Hellenic coastal waters within (WFD). An adapted decision tree used for integrating results WFD Basque country was applied. Modifications lie evaluation physicochemical a eutrophication index developed Eastern Mediterranean waters. Results hydromorphological, and biological elements are presented. The chemical...

The ecosystem approach to fisheries management needs information of not just where bottom trawlers operate but also on their impact the seabed, which is highly relevant EU Marine Strategy Framework Directive (MSFD) Descriptor D6, seafloor integrity. In this study, we assess benthic trawling in Eastern Mediterranean areas primarily fished by Greek fleet. Seabed habitat sensitivity was modelled using macrofaunal longevity and biomass relationship based data from more than 800 locations,...

This study reports four alien polychaete species new to the marine fauna of Greece. These are -Pseudopolydora paucibranchiata (family Spionidae),Paraprionospio coora Spionidae), Marphysa disjuncta Eunicidae), and Chaetozone corona(family Cirratulidae). Another Chaetozone, though not an one, gibber is reported here from Greek waters. All them have been currently coasts Turkey (Aegean or Levantine Seas).

The diversity and distribution of polychaetes in the coastal area EEZ Republic Cyprus is presented based on both literature records new data acquired a wide range environmental monitoring programmes research projects. A total 585 polychaete species belonging to 49 families were reported waters; among them, 205 (34%) recorded only, 149 (26%) our own data, 231 spp. (40%) from data. 51 identified as non-indigenous; 32 confirmed alien species, 4 considered cryptogenic, 15 questionable there...

Abstract Many indicators have been developed to assess the state of benthic communities and identify seabed habitats most at risk from bottom trawling disturbance. However, large variety their development application under specific geographic areas management contexts has made it difficult evaluate wider utility. We compared complementarity/uniqueness, sensitivity, selectivity 18 pressure trawling. Seventeen common datasets with broad regional representation covering a range gradients...

Marphysa is one of the largest genera in family Eunicidae, containing 76 valid species. However, among them there are only five species that share diagnostic characters having composite falcigers inferior setae and branchiae confined anterior body. These relatively rare less described while their original descriptions differentiation mainly based on features believed to be age-specific today. In this study, type-materials M. adenensis, purcellana gemmata have been re-examined re-described...

Abstract Marine mussels are ubiquitous and their tough byssal threads allow for the formation of expansive, age‐aggregated mats known as mussel matrices which can host marine invertebrates algal macro‐benthic communities playing an important role in food‐web dynamics. Yet, despite significant implications biodiversity intertidal ecosystem functioning, size, individual morphology community arrangement determining structure associated has never been investigated.

The Messinia region, located in the South – West of Peloponnese, Greece, is an ecologically valuable area comprising several important coastal habitats (including lagoons, seagrass meadows, and Mediterranean rhodolith beds) eliciting its inclusion Natura 2000 network. Land-based anthropogenic pressures are likely to influence ecological status this zone. Here we identify those regional use physico-chemical elements ecosystem, macrofauna communities assess level environmental degradation...
