“…In the series of materials devoted to the consequences of a dredging campaign in Göteborg harbor, Sweden, to eelpout (Z. viviparous), as a sentinel species, TBARS did not show inter-site differences (Almroth et al, 2005). Similarly, in the liver of labrid fish (Coris julis) despite the variations in the antioxidant enzyme activities, there was no significant difference in TBARS concentrations (Sureda et al, 2006).…”

“…Higher activities of GST, GPx and GR were detected in liver of teleost C. julis from two stations with seagrass Caulerpa species that produce toxic methabolite Caulerpenyne, as compare to fish from the area where Caulerpa species were absent. At that, no statistical difference was found in catalase activity between the groups (Sureda et al, 2006). However, in the case of worsening of environmental conditions caused by dredging of contaminated sediments, high activities of catalase, GR and GPx in red mullet M. barbatus sampled at a disposal site for dredged sediments was demonstrated by Regoli and colleagues (2002).…”

“…They may originate from miscellaneous sources such as chemical and drug manufacture, domestic sewage, polymer and petrochemical-based industries, oil refineries, mining, glass blowing, battery manufacture and many others. Hydrological changes, hydromorphological degradation and invasive species also can contribute to the set of stressing factors (Amado et al, 2006;Sureda et al, 2006;dos Anjos et al, 2011). According to origin, two primary routes of pollution can be selected: (1) point-source pollution and (2) non-point-source pollution.…”

“…Meyer et al (2003) stressed that the study of spot (L. xanthurus) (Roberts et al, 1987) and killifish (larvae of F. heteroclitus) from the same polluted area demonstrated different species-specific sensitivity of Mn-SOD and Cu,Zn-SOD activation. Connecting tissue specificity of enzymes studied in field experiments, the enzymes of liver are considered to be less sensitive to some kinds of pollution than other tissues, because of the best antioxidant adaptation in the liver of fish, since despite the variations in the antioxidant enzyme activities, there was no significant difference in malondialdehyde concentration (Sureda et al, 2006).…”

“…Their presence induces drastic changes in faunistic composition and abundance of the affected systems, and thus they have become a serious problem in the western Mediterranean (Pandolfo and Chemello, 1995;Bellan-Santini et al, 1996;Argyrou et al, 1999;Buia et al, 2001). Caulerpa species produce anti-herbivorous secondary metabolites (Amade and Lemee, 1998;Jung et al, 2002), the main one being caulerpenyne, which negatively affect grazing organisms (Boudouresque et al, 1996;ParentMassin et al, 1996;Amade and Lemee, 1998;Pesando et al, 1998;Sureda et al, 2006;Sureda et al, 2008) and chemically change the environmental conditions of the habitat (Amade and Lemee, 1998;Sureda et al, 2006).…”

SUMMARY: A two-year study focusing on the associated polychaete assemblages revealed that the degradation of the Posidonia oceanica seagrass meadows, together with the colonisation of rhizomes by invasive Caulerpa racemosa in the Balearic Islands, have produced important changes in the ecosystem functioning, and have therefore affected the benthic faunal communities. The highest abundance and number of species occurred in C. racemosa from August to December. The species composition of the polychaete assemblage in C. racemosa is similar to that of P. oceanica but abundances of shared species differ between Caulerpa and Posidonia. Abundance, number of species and diversity were positively correlated with C. racemosa biomass. The spatial complexity provided by the network of C. racemosa fronds and stolons seemed to combine with that of the remaining seagrass mat to support a well developed polychaete assemblage. Although invaded meadows harboured significantly modified polychaete assemblages when compared with living P. oceanica meadows, the main impacts seem to be non-harmful (i.e. increased abundance and number of species) and mainly affect their seasonal patterns, which is a direct consequence of the corresponding biomass seasonality of C. racemosa.Keywords: Posidonia oceanica, Caulerpa racemosa, Polychaeta, species diversity, trophic guilds, taxonomic distinctness, introduced species, Mediterranean. RESUMEN: Cambios en la comunidad de poliquetos asociados a la invasión de Caulerpa raCemosa var. CylindraCea (Chlorophyta: Caulerpales): estructura de comunidad, estrategias tróficas y distinción taxonómica. -En las Islas Baleares, la degradación de las praderas de Posidonia oceanica junto con la colonización de los restos de rizoma por Caulerpa racemosa conllevan importantes cambios en el funcionamiento del ecosistema, los cuales afectan especialmente a las comunidades de invertebrados. El presente estudio muestra que, a lo largo de dos años, las mayores abundancias y diversidades de poliquetos en rizomas invadidos por C. racemosa se han encontrado en agosto y septiembre. La composición específica en dichos rizomas invadidos es muy similar a la propia de las praderas de P. oceanica, si bien algunas de especies coincidentes difieren claramente en abundancia. La biomasa de C. racemosa muestra una correlación positiva con la abundancia, número de especies y diversidad de poliquetos. La complejidad espacial asociada a los frondes y estolones de C. racemosa se combinan con los restos de rizoma, generando un hábitat capaz de mantener una comunidad de poliquetos bien estructurada. Sin embargo, a pesar de las diferencias encontradas entre las respectivas comunidades de poliquetos, el impacto de la invasión parece no ser negativo (e.g. aumentan la abundancia de algunas especies y la diversidad específica) y afecta principalmente a su pauta estacional, siendo consecuencia directa de la estacionalidad del ciclo vegetativo de C. racemosa.

Plastic has become indispensable for human life. When plastic debris is discarded into waterways, these items can interact with organisms. Of particular concern are microscopic plastic particles (microplastics) which are subject to ingestion by several taxa. This review summarizes the results of cutting-edge research about the interactions between a range of aquatic species and microplastics, including effects on biota physiology and secondary ingestion. Uptake pathways via digestive or ventilatory systems are discussed, including (1) the physical penetration of microplastic particles into cellular structures, (2) leaching of chemical additives or adsorbed persistent organic pollutants (POPs), and (3) consequences of bacterial or viral microbiota contamination associated with microplastic ingestion. Following uptake, a number of individual-level effects have been observed, including reduction of feeding activities, reduced growth and reproduction through cellular modifications, and oxidative stress. Microplastic-associated effects on marine biota have become increasingly investigated with growing concerns regarding human health through trophic transfer. We argue that research on the cellular interactions with microplastics provide an understanding of their impact to the organisms' fitness and, therefore, its ability to sustain their functional role in the ecosystem. The review summarizes information from 236 scientific publications. Of those, only 4.6% extrapolate their research of microplastic intake on individual species to the impact on ecosystem functioning. We emphasize the need for risk evaluation from organismal effects to an ecosystem level to effectively evaluate the effect of microplastic pollution on marine environments. Further studies are encouraged to investigate sublethal effects in the context of environmentally relevant microplastic pollution conditions.
