“…Several studies have reported the enhancement of antioxidant enzyme activities in polychaetes to cope with metal stress both in laboratory exposures and in the field (e.g. Cd, Cu) (Geracitano et al 2004, FerreiraCravo et al 2007, Sun and Zhou 2008, Douhri and Sayah 2009). This result is confirmed by the statistical analyses, which showed a significant relationship between the Cd concentrations and SOD and CAT activities in polychaete tissues associated with the sites within Cádiz Bay.…”

SUMMARY:The environmental quality of the southwest Iberian coast was assessed in different areas (Ria Formosa Lagoon, Guadiana Estuary and Cádiz Bay) focusing on metal contamination (Cd, Cu, Ni, Pb and Zn) in Nereis diversicolor whole tissues. In addition, associated toxicological effects were assessed using a multibiomarker approach combining several conventional biomarkers. The set of biomarkers selected included antioxidant enzymes (catalase, superoxide dismutase and glutathione peroxidase), metallothionein and lipid peroxidation. N. diversicolor from the Ria Formosa Lagoon, Guadiana River and Cádiz Bay responded differently to metal contamination with different biomarker responses showing a clear site trend, suggesting different sources and/or magnitudes of contamination. Cadmium was a source of oxidative stress in polychaetes, mainly in Cádiz Bay, with a significant influence on antioxidant enzymes and enhancement of lipid peroxidation. The highest MT concentrations were in the Ria Formosa Lagoon and in the Guadiana River, where there was a direct relationship with high nickel concentrations. Biomarker responses of N. diversicolor are useful tools for environmental quality assessment on the southwest Iberian coast, and more specific metal biomarkers should be included in future assessments.Keywords: biomarkers, metals, Nereis diversicolor, antioxidant enzymes, metallothionein, lipid peroxidation, southwest Iberian coast.RESUMEN: Biomarcadores en Nereis diversicolor (Polychaeta: nereididae) como herramientas de gestión de la evaluación del medio amBiente en el suroeste de la Península iBérica. -El estudio de la calidad ambiental de los ecosistemas costeros del SO de la Península Ibérica (Ría Formosa, estuario del Guadiana y bahía de Cádiz) en relación a la contaminación metálica (Cd, Cu, Ni, Pb y Zn) se ha llevado a cabo mediante el análisis del contenido de metales en Nereis diversicolor. Además, los efectos ecotoxicológicos fueron evaluados mediante una aproximación "multibiomarcadores", en donde se combinan varios biomarcadores convencionales. La batería de biomarcadores seleccionadas han sido: las enzimas antioxidantes (catalasa (CAT), superóxido dismutasa (SOD) y glutatión peroxidasa (GPX), metalotioneína (MT) y peroxidación lipídica (LPO). Los ejemplares de N. diversicolor recolectados en las distintas zonas, mostraron una respuesta diferente a la contaminación metálica, lo que sugiere diferentes fuentes y/o magnitud de la contaminación. Los niveles de cadmio estan directamente relacionados con las actividades SOD y CAT y los niveles de LPO. En el caso del níquel, sus niveles se hallaban correlacionados positivamente con los de MT en la Ría Formosa y en el río Guadiana. La integración de las respuesta de los biomarcadores en N. diversicolor ha demostrado ser una herramienta útil para la evaluación de la calidad ambiental de los ecosistemas costeros del SO de la Península Ibérica.

“…Additionally, they found the activity of the antioxidant enzyme glutathione reductase, which acts as a free radical scavenger in the detoxification of contaminants, was reduced in response to elevated copper. Geracitano et al (2003) exposed the nereid L. acuta to elevated levels of copper and found that the enzyme catalase, which is thought to be produced in response to oxidative damage in the cell, increased in activity. Finally, Rhee et al (2007) cloned the gene for the antioxidant enzyme glutathione S-transferase in Neanthes succinea (Family Nereididae), and found the expression of this gene increased significantly in response to elevated copper concentrations.…”

Polychaetes are usually the most abundant taxon in benthic communities and have been most often utilized as indicator species of environmental conditions. This review finds that, while the use of indicator species for a particular pollutant is not simple, polychaetes can provide a useful means of assessing the effects of poor environmental conditions. Polychaetes may be used as sensitive monitors of water quality especially in terms of the effects of pollutants on life history characteristics. They may also be utilized as general indicators of community diversity but those species indicative of lower diversity may differ geographically and temporally. While sewage is often a mixture of high organic material and other pollutants such as heavy metals and pesticides, high organic situations associated with aquaculture facilities indicates that members of the Capitella capitata species complex and the dorvilleid genus Ophryotrocha are often dominant. Some species of polychaetes are able to live in sediments very high in trace metal content and body burden of these metals often does not reflect sediment concentrations due to regulation by these species. Many species seem relatively resistant to organic contaminants and pesticides and the effects of these pollutants on life history characteristics of these species may provide a more sensitive assay method. Recent studies using biomarkers in polychaetes to indicate general heavy metal or pesticide contamination has shown some success. Polychaete species known to occur in appreciable densities in the Gulf of Nicoya, Costa Rica, and which have been most often used as indicator species of pollution, are listed as potential taxa for environmental monitoring in this tropical estuary. Rev. Biol. Trop. 56 (Suppl. 4): 11-38. Epub 2009 June 30.Key words: polychaete, indicator species, marine pollution, community diversity, heavy metals, pesticides, organics, biomarkers, tropical, Costa Rica.The polychaetes have long been an obvious choice to act as representative species in the analysis of the health of benthic communities as they are usually the most abundant taxon taken in benthic samples, both in terms of the number of species and numerical abundance. Additionally, unlike nektonic or reptant organism, the polychaetes usually live within the sediments or attached to hard surfaces and, while their larvae may be capable of long distance transport, the adults are relatively inert. This relative immobility ensures chronic exposure to any toxic materials in the environment rather than the episodic exposures of a more vagile organism. Any long-term changes in the wellbeing of the benthos should be reflected in the polychaete community .The life history characteristics of polychaetes also make them good candidates to act as indicator species. The epibenthic filter feeders maximize their exposure to any harmful materials within the water column as they process relatively large amounts of water during feeding. Deposit feeding and interstitial species, which are in intimate c...

“…relating to the external shape, physiological or behavioural character) variations of adaptive value to individuals. Morphological changes with adaptive value have been found in several species of polychaetes, particularly in the Nereididae (Geracitano et al, 2004a). Ecophenotypic factors refer to morphological changes resulting from environmental changes, such as contamination or changes in the concentration of an abiotic factor, and they can also generate genetic alterations (Backmann et al, 1995;Geracitano et al, 2002Geracitano et al, , 2004bBocchetti et al, 2004;Ferreira-Cravo et al, 2009;Mouneyrac et al, 2010;Ahrens et al, 2013).…”

The examination of a large number of specimens in the context of taxonomic and ecological studies may lead to the discovery of morphological anomalies. The aim of this study was to describe the morphological anomalies observed in some individuals of Perinereis anderssoni and Perinereis ponteni collected in various regions of the Brazilian coast. A total of 290 specimens were analysed from along the northern and southern Brazilian coast, and 21 of these presented morphological anomalies, such as variations in the number of tentacular cirri and eyes, completely or basally fused antennae, chaetigers with three parapodia, and others. Perinereis anderssoni presented the highest number of anomalous individuals, and the most frequent morphological anomaly was the presence of a single antenna and nine tentacular cirri. Anomalous individuals of P. ponteni with seven tentacular cirri were also commonly collected. Ilha do Mel (PR) was the area with the highest percentage of individuals with anomalies (12.96%), followed by Martim de Sá (SP) (10.31%), São Francisco do Conde (BA) (8.33%), Tambaba (PB) (5.55%) and Itaipu (RJ) (1.92%). Most of the sampling locations have a history of contamination by a diverse array of pollutants. We provide background information for the morphological changes observed in two species that occur along the Brazilian coast, but additional studies are needed to confirm the real cause of these anomalies and their effect on the population structure of these ecologically important species.
