The distribution of polychaetes associated with an offshore gas platform built on a muddy-sandy bottom in the northern Adriatic Sea was investigated with emphasis on their feeding structure. Polychaete species were collected at different distances from the rig using a Van Veen grab. Assessment of the polychaete community and trophic groups for impacts related to the presence of the platform dem...

A two-factor classification system for types of reproductive modes within the Polychaeta is described. The classification is based on the type ofIarval development and the fate of the female gametes (free-spawned or brooded in a variety of ways). A compilation ofinformation from the literature allowed the classification of 306 species. The Orders Phyllodocida and Spionida show the greatest dive...

The study of ecosystem functioning - the role which organisms play in an ecosystem - is becoming increasingly important in marine ecological research. The functional structure of a community can be represented by a set of functional traits assigned to behavioural, reproductive and morphological characteristics. The collection of these traits from the literature is however a laborious and time-c...

resection is the most common treatment choice for sigmoid volvulus, a common complication in our region. a new minimally invasive technique for sigmoid resection with local anesthesia was done in this study. this method is invented to avoid general on regional anesthesia in high-risk patients. nineteen patients were evaluated and then 14 were enrolled in this study. sigmoidectomy with a left lo...

Anthropogenic plastic pollution is a global problem. In the marine environment, one of its less studied effects is the transport of attached biota, which might lead to introductions of non-native species in new areas or aid in habitat expansions of invasive species. The goal of the present work was to assess if the material composition of beached anthropogenic litter is indicative of the raftin...

Terebelliformia comprises a large group of sedentary polychaetes which live from the intertidal to deep sea. The majority in tubes and are selective deposit feeders. This study synthesises current knowledge this group, including their distribution, different biogeographic regions. We highlight new methodologies being used describe them resolution species complexes occurring group. main aim revi...

A large number of suspension-feeding aquatic animals (e.g. bivalves, polychaetes, ascidians, bryozoans, crustaceans, sponges, echinoderms, cnidarians) have specialized in grazing on not only the 2 to 200 μm phytoplankton but frequently also the 0.5 to 2 μm free-living bacteria, or they have specialized in capturing larger prey, e.g. zooplankton organisms. We review the different particle captur...

Background The last annotated checklist of marine polychaetes in Greece was published in 2001. Since then, global taxonomic progress, combined with many new species records for Greece, required a thorough review of the taxonomic, nomenclatural and biogeographic status of the national species list. This checklist revises the status of all extant polychaete species reported from the Greek Exclusi...
